    Full Text Available The environmental movement is affecting all industries, but the textile and automotive industries are two of the few that are constantly being criticized. The automotive industry is the subject of much research, it is the largest manufacturing activity, there is a complex supply chain, is resource intensive and emits various hazardous gases and waste products. The article reviews the current state of automotive industry regarding the textile application. Automotive textiles have been classified as belonging to a category called “Mobiltech” which is one of the main streams of technical textiles. The term means all type of textile components e.g. fibers, filaments, yarns and the fabric used in automobiles. They are classed as technical textile because of the very high performance specifications and special properties required, different from those used in clothing and other applications. The performance of the automotive textiles depends on the fibre properties, fabric structures and various finishes used in the manufacturing processes. After a short presentation of used fibres in car interiors, with advantages and disadvantages it is presented the sustainable textile solutions for the automotive industry. The paper focuses in particular of the use of recycling of textile waste to highlight how the processes of recycled textiles and sustainable textiles production are linked in the automotive sector. A case study with Ford Motor Company outlines and examines their design, development and manufacture process for automotive textiles for car seat coverings and interiors

    Full Text Available The textile industry plays a pivotal role in Pakistan’s economy. The industry‘s share for overall manufacturing activity is 46%; in the export sector it is 68%; in value addition it is 9% of GDP and in providing employment it is 38%, in addition to the foreign exchange earnings, investment and contribution to the value added industry. In spite of this major contribution, the textile industry is at a severe risk due to hefty increases in energy costs. Keeping in view of these challenges in order to technically support the textile industry, energy audit of a textile mill ihas been carried out and areas of energy wastage are identified with an estimated cost saving of almost Rs. 6.8 million. Finally recommendations are given for cost effective measures for efficient energy usage, estimation of implementation costs and payback periods.KEYWORDS:   energy; audit; loss; consumption; economy

    This paper presents results from a case-control study carried out in the county of Mataro, Spain. The study was designed to investigate the possible causes of an unusually high mortality rate from bladder cancer in Mataro county as compared to Spain as a whole, and this report focuses on occupational exposures. The study is based on 57 cases who were hospitalized for or died from bladder cancer between 1978 and 1981. Two controls per case were matched for sex, age, residence, and date of either hospitalization or death. Information was collected on smoking, coffee drinking, and occupation. Occupational histories were then evaluated and coded blind by a group of occupational health physicians. Analyses were carried out by means of conditional logistic regression. Among a group of common occupational sectors, an increased risk for past employment in the textile industry (OR = 2.2; p = .038) was found. Further analyses indicated that the risk is particularly elevated (OR = 4.41; 95% confidence limits; 1.15-16.84) for subjects who worked in dyeing or printing and who were most probably exposed to azo-dyes. Exposure in the textile industry may be responsible for 16% of the bladder cancers in the Mataro area. A list of dyes commonly used in the Mataro textile industries was compiled and cross-checked with lists of substances tested or evaluated for carcinogenesis.

The research is qualitative in nature and structure by means of a single case study. The multiple sources of evidence were: content analysis of the company's website, interviews (with management and employees of the operational area and direct observation. From the information obtained, it was possible to do triangulation of data and infer that the company has no defined concepts and practices of sustainability. Moreover, it might be found that it faces some barriers that hinder the promotion of sustainable development in its entirety, as the lack of knowledge (design and sustainable practices, lack of strategic planning and business management.

    Full Text Available This article explores corporate governance issues like ownership structure, gender diversity accountability, risk management and internal audit at managerial level of a textile company listed on the Bucharest stock exchange. For this reason, secondary data was used as information collection tool. Results of the study underline the conclusion that, corporate governance is being implemented in companies belonging to the textile industry of Romania although correlated with some weaknesses. Analyzed documents confirm that the chosen textile company is trying to implement various accepted corporate governance policies, to stay competitive. The manufacturing processes were constantly improved involving a variety of techniques, with the purpose for diminishing environmental negative impact by eliminating waste. The board of directors as well as the top-management has a good understanding of the responsibilities for each member in order to ensure good corporate governance. The lack of a trade union could be the causative factor of wage inequality and loss of a stronger worker voice. Although the result of external constraints, we identified a process for constant enhancement of corporate governance in the company. The implementation of the code of corporate governance contributed to improvement in performance especially share value. Future research directions aimed extending the sample by selecting several other companies from different industries, for comparison.

    Full Text Available One of the main problems faced by large retailers is related to the lack of supply in display racks, the so called stock-out points. Studies have been made since the sixties, which show that progress related to this subject is limited. Stock-out levels are around 8.3%. Furthermore, literature on the subject is insufficient, as very few studies have been dedicated to investigating the causes of stock-out. The present study aims to collect stock-out data from a large textile retailer for a product category and elaborate a tree of stock-out causes. Qualitative and quantitative methods were used in this research, through software and interviews, in order to generate and refine our results. From this approach, it was possible to identify that 38% of the causes of stock-outs are within the store, that is, the product is not available in the sales area, but in the back end.

    Environmental concerns associated with textile processing had placed the textile sector in a Southern State of India under serious threat of survival. The textile industries were closed under the orders of the Statutory Board for reason of inadequate compliance to environmental discharge norms of the State for the protection of the drinking water source of the State capital. In compliance with the direction of the Board for zero effluent discharge, advanced treatment process have been implemented for recovery of boiler feed quality water with recourse to effluent recycling/reuse. The paper describes to a case study on the adequacy assessment of the full scale effluent treatment plant comprising chemical, biological and filtration processes in a small scale textile industry. In addition, implementation of measures for discernable improvement in the performance of the existing units through effective operation & maintenance, and application of membrane separation processes leading to zero effluent discharge is also highlighted.

    2013-09-01

    Full Text Available This article reports a case study research of a textile module at the year-long module based course in arts and handicrafts at the Teacher Education at Nesna University College. The textile modules main focus is to give the students practical aesthetic experience as well as basic knowledge and skills of textiles and their qualities. The module has been regularly assessed by teachers and students, revised and developed, and offered for several years. Assessments show that students appreciate the module and its focus on basic knowledge and skills in textile. However, as an arts and handicrafts teacher at the college level, I’ve observed that students basic skills are underdeveloped, and some have unrealistic insight, demands and expectations about how much knowledge and experience a thirty five hour course in textiles will give. Some students with little or no textile experience have problems with interpreting and understanding the written task and also “getting started”. Detailed explanations concerning the content seem to confuse rather than enlighten, and students’ fear of failing gives me as a teacher several thoughts about cause and effect. In this case study a qualitative survey of a textile module’s schedule, student’s questions and desires for explanations, their written tasks, products and assessments are being used to enlighten and understand the problem. The results show that a detailed explanation of a practical aesthetic assignment does not contribute to increased understanding with some students, whereas a confrontation of the practical process will.

    The textile industry is a favor to the Tunisian economy by offering several job positions. However, it's not environmentally friendly. In fact, textile industries discharge high volumes of wastewater which contain several toxic pollutants such as dyes, fixator, and whiteness. In our study, Pseudomonas peli, isolated and characterized from Oued Hamdoun (center of Tunisia), was found able to decolorize textile effluent about 81 % after 24 h shaking incubation. On the other hand, the in vitro antiproliferative effects of the untreated and treated effluent was evaluated by their potential cytotoxic activity using the MTT colorimetric method against three human cancer cell lines (A549, lung cell carcinoma; HT29, colon adenocarcinoma; and MCF7, breast adenocarcinoma). Results showed that intact textile effluent and its content azo dyes didn't inhibit the proliferation of all tested cell lines. However, the cytotoxic effect was remarkable when we tested effluent obtained after treatment by P. peli in a dose-dependent manner. This activity was attributed to the presence, in our treated effluent, of some azo products of dyes which are responsible for inhibition of human cell lines proliferation. Thus, the use of this strain for testing on the industrial scale seems impossible and disadvantageous.

    A process integration study has been made in the wool company `DROBE`, located in Kaunas, Lithuania. The study is limited to the finishing workshop because this workshop is by far the largest consumer of thermal energy at the factory. Theoretical and practical heat exchanger networks are generated, and several possibilities of waste heat utilisation have been evaluated. By local optimisation of two machines with the largest energy consumption in the finishing workshop it will be possible to save 11.1% of thermal energy equivalent to about 1,560 MWh/year. With the current expenses for production of thermal energy this amounts to 125,000 Lt/year. (1 kWh = 0.08 Lt). (au)

    The decolouration and mineralization of reactive dye C.I. Reactive Black 5, a well-known representative of non-biodegradable azo dyes, by means of ultrasonic irradiation at 20, 279 and 817 kHz has been investigated with emphasis on the effect of various parameters on decolouration and degradation efficiency. Characterization of the used ultrasound systems was performed using calorimetric measurements and oxidative species monitoring using Fricke and iodine dosimeter. Experiments were carried out with low frequency probe type, and a high-frequency plate type transducer at 50, 100 and 150 W of acoustic power and within the 5-300 mg/L initial dye concentration range. Decolouration, as well as radical production, increased with increasing frequency, acoustic power, and irradiation time. Any increase in initial dye concentration results in decreased decolouration rates. Sonochemical decolouration was substantially depressed by the addition of 2-methyl-2-propanol as a radical scavenger, which suggests radical-induced reactions in the solution. Acute toxicity to marine bacteria Vibrio fischeri was tested before and after ultrasound irradiation. Under the conditions employed in this study, no toxic compounds were detected after 6 h of irradiation. Mineralization of the dye was followed by TOC measurements. Relatively low degradation efficiency (50% after 6 h of treatment) indicates that ultrasound is rather inefficient in overall degradation, when used alone.

    2005-01-01

    In recent years, supply chain management (SCM) has been in popularity as a new management philosophy for all industries, including textile and apparel industries. The textile-apparel supply chain is relatively complex because it encompasses many participants such as yam manufacturers, fabric manufacturers, garment manufacturers and retailers. Although many scholars are engaged in researching SCM in textile and apparel industries, a systematic classification of textile-apparel chain does not exist. The paper proposes three types of textile-apparel chain,nominated vertical integration chain, traditional sourcing chain and 3P-hub (third party as the hub) chain. Different coordinators exist in different types of chain. Three Hong Kong headquartered companies, Esquel Group, TAL Apparel Ltd., and Li & Fung (Trading) Ltd. are used as cases responding to each type of the structures respectively.

    In the present study the feasibility of the use of a bacterial batch sequential anaerobic-aerobic process, in which activated sludge was used in both parts of the process, for pretreatment of wastewater generated by a textile dyeing factory has been considered. Activated sludge used in the process was obtained from a municipal wastewater treatment plant and adapted to real dyeing wastewater using either an anaerobic-only or an anaerobic-aerobic process over a period of 90 days. The use of activated sludge adapted using the anaerobic-aerobic process resulted in a higher overall decolorization efficiency compared to that achieved with activated sludge adapted using the anaerobic-only cycles. Anaerobic and aerobic periods of around 34 and 22 hours respectively resulted in an effluent with chemical oxygen demand (COD) and color content which met the standards for discharge into the centralized wastewater treatment plant of the industrial estate in which the dyeing factory was situated. Neutralization of the real dyeing wastewater and addition of carbon source to it, both of which results in significant increase in the cost of the bacterial treatment process, was not found to be necessary to achieve the required discharge standards.

    Full Text Available The rapid development of China’s textile industry has led to consumption and pollution of large volumes of water. Therefore, the textile industry has been the focus of water conservation and waste reduction in China’s 13th Five-Year Plan (2016–2020. The premise of sustainable development is to achieve decoupling of economic growth from water consumption and wastewater discharge. In this work, changes in the blue water footprint, grey water footprint, and the total water footprint of the textile industry from 2001 to 2014 were calculated. The relationship between water footprint and economic growth was then examined using the Tapio decoupling model. Furthermore, factors influencing water footprint were determined through logarithmic mean Divisia index (LMDI method. Results show that the water footprint of China’s textile industry has strongly decoupled for five years (2003, 2006, 2008, 2011, and 2013 and weakly decoupled for four years (2005, 2007, 2009, and 2010. A decoupling trend occurred during 2001–2014, but a steady stage of decoupling had not been achieved yet. Based on the decomposition analysis, the total water footprint mainly increased along with the production scale. On the contrary, technical level is the most important factor in inhibiting the water footprint. In addition, the effect of industrial structure adjustment is relatively weak.

    2015-01-01

    Steel cable was chosen for the lower end of the drogue and main parachute risers on NASA's Orion Multi Purpose Crew Vehicle Parachute Assembly System (CPAS) to protect the risers from extreme temperatures and abrasion should they contact the crew module during deployment, as was done for Apollo. Due to the weight and deployment complexity inherent in steel, there was significant interest in the possibility of substituting textile for steel for the drogue and main parachute risers. However, textile risers could be damaged when subjected to high temperature and abrasion. Investigations were consequently performed by a subset of the authors to determine whether sacrificial, non-load-bearing textile riser covers could be developed to mitigate the thermal and abrasion concerns. Multiple material combinations were tested, resulting in a cover design capable of protecting the riser against severe riser/crew module contact interactions. A feasibility study was then conducted to evaluate the performance of the textile drogue riser cover in relevant abrasive environments. This paper describes the testing performed and documents the results of this feasibility study.

    2015-05-01

    Full Text Available In this paper we have analysed the current state of reporting CSR activity of companies activating in the textiles and apparel industry. Noticing that the number of companies that invest in CSR programs is increasing on a world-wide level and in the last years even in Romania, we wanted to analyse the situation of the companies from a field of activity less involved in CSR programs. The importance of CSR programs has increased more and more in recent times, from a reputation point of view but mostly of reasons of a stronger involvement of companies in the communities where they are present, but also in educating their own employees which become more motivated if they can participate in various actions undertaken through CSR programs. The implementation of such programs adds value to the businesses developed by the company, taking into account that more segments of consumers have expressed their availability to buy products made by companies that promote such programs. The visibility of CSR projects is made by presenting the programs that the company promotes in sustainability reports, by using means and indicators defined under the Global Reporting Initiative. Following the study we have made, we found out that although world-wide the number of companies that have CSR programs and make sustainability reports is increasing, the number of companies in the textiles and apparel industry that make such reports is very small.

    Full Text Available Designing of lifting, pushing and pulling activities based on the physical and physiological capabilities of the operators is essential. The purpose of this study is to analyze manual material handling (MMH working posture of the operators using 3D Static Strength Prediction Program (3DSSPP software and to identify major areas causing long last injury of operators. The research has investigated the fit between the demands of tasks and the capabilities of operators. At the existing situations, the actual capabilities of operators have been computed with the help of 3DSSPP software and compared with NIOSH standards. Accordingly, operators' working posture is at an unacceptable position that exposes them for musculoskeletal disorders. Then, after the improvement of the design of MMH device (cart's roller, the result showed that the forces required by the operators to push and pull the sliver cans have been reduced from 931.77 Newton to 194.23 Newton. Furthermore, improvement of MMH cart's roller has reduced the awkward posture of operators and the risk of musculoskeletal disorders. The improved manual material handling design also saves about 1828.40 ETB per month for the company.

    Institute of Scientific and Technical Information of China (English)

    2005-01-01

    Water hyacinth (Eichhornia crassipes (Mart.) Solms) is a prolific free floating aquatic macrohpyte found in tropical and subtropical parts of the earth. The effects of pollutants from textile wastewater on the anatomy of the plant were studied. Water hyacinth exhibits hydrophytic adaptations which include reduced epidermis cells lacking cuticle in most cases, presence of large air spaces (7~50 μm), reduced vascular tissue and absorbing structures. Textile waste significantly affected the size of root cells.The presence of raphide crystals was noted in parenchyma cells of various organs in treated plants.

    Eleven years experience of textile finish resin patch testing of suspected textile dermatitis patients revealed 15 cases of allergic textile dermatitis among 428 patients tested. Ten of the 15 patients had a relevant positive patch test to one or more of a limited series of textile finishes; 1...... was negative and 4 were not tested with textile finishes. All 15 patients were formaldehyde sensitive. No unexpected, relevant, positive textile finish resin patch test was found. In this study a negative patch test to formaldehyde virtually excluded allergic contact dermatitis from textile finishes....

  17. Evaluation of Barriers of Corporate Social Responsibility Using an Analytical Hierarchy Process under a Fuzzy Environment—A Textile Case

    2015-03-01

    Full Text Available The ventilating crisis of Corporate Social Responsibility (CSR issues in the textiles industry resulted in the engagement of many researchers in the analysis of CSR and its related factors throughout the globe. Some researchers in developed nations extend their policies beyond the boundary of CSR in the textiles industry, but some developing contexts are still limited to this boundary, including India, due to facts that have not yet been revealed. Hence, to fill this gap, this study reveals the factors that are resisting the implementation of CSR in the textiles industry with the assistance of a proposed model, and this model is validated with a case industry situated in southern India. Common barriers are collected through various reliable means, and among those common barriers, the essential barrier was identified with the assistance of the case industrial manager through an Analytical Hierarchy Process (AHP under a fuzzy environment. The results show that financial constraints comprise the main barrier to the implementation of CSR in the Indian textiles industry, which is then further validated with feedback from case industry managers. This study offers both societal and scientific insights, identifies limitations, and provides an approach that may be extended in the future once additional factors are implemented.

    2017-02-17

    This paper describes the use of atomic force microscopy (AFM) to investigate the interactions between explosives crystals and different surfaces. Crystals of TNT, PETN and RDX were mounted onto tipless AFM cantilevers and repeatedly brought into contact with a range of surfaces (n=15), including textile and non-textile surfaces. The adhesion force during each contact was measured, and the results are presented in this work. The results suggest that explosives crystals display a higher adhesion to smoother, non-textile surfaces, particularly glass. This finding may be of use for forensic explosives investigators when deciding the best types of debris to target for explosives recovery.

    2011-10-01

    The textile sludge is an inevitable solid waste from the textile wastewater process and is categorised under toxic substances by statutory authorities. In this study, an attempt has been made to encapsulate and solidify heavy metals and dyes present in textile sludge using polypropylene and Portland cement. Sludge samples (2 Nos.) were characterized for pH (8.5, 9.5), moisture content (1.5%, 1.96%) and chlorides (245mg/L, 425.4mg/L). Sludge samples were encapsulated into polypropylene with calcium carbonate (additive) and solidified with cement at four different proportions (20, 30, 40, 50%) of sludge. Encapsulated and solidified cubes were made and then tested for compressive strength. Maximum compressive strength of cubes (size, 7.06cm) containing sludge (50%) for encapsulation (16.72 N/mm2) and solidification (18.84 N/mm2) was more than that of standard M15 mortar cubes. The leachability of copper, nickel and chromium has been effectively reduced from 0.58 mg/L, 0.53 mg/L and 0.07 mg/L to 0.28mg/L, 0.26mg/L and BDL respectively in encapsulated products and to 0.24mg/L, BDL and BDL respectively in solidified products. This study has shown that the solidification process is slightly more effective than encapsulation process. Both the products were recommended for use in the construction of non-load bearing walls.

    Increasing customer demand for durable and functional apparel manufactured in a sustainable manner has created an opportunity for nanomaterials to be integrated into textile substrates. Nanomoieties can induce stain repellence, wrinkle-freeness, static elimination, and electrical conductivity to fibers without compromising their comfort and flexibility. Nanomaterials also offer a wider application potential to create connected garments that can sense and respond to external stimuli via electrical, color, or physiological signals. This review discusses electronic and photonic nanotechnologies that are integrated with textiles and shows their applications in displays, sensing, and drug release within the context of performance, durability, and connectivity. Risk factors including nanotoxicity, nanomaterial release during washing, and environmental impact of nanotextiles based on life cycle assessments have been evaluated. This review also provides an analysis of nanotechnology consolidation in the textiles market to evaluate global trends and patent coverage, supplemented by case studies of commercial products. Perceived limitations of nanotechnology in the textile industry and future directions are identified.

    Pathak, Vinayak V; Kothari, Richa; Chopra, A K; Singh, D P

    2015-11-01

    Potential of Chlorella pyrenoidosa was experimentally investigated for phycoremediation and dye removal from textile wastewater (TWW) in batch cultures. Growth of alga was observed at various concentration of textile wastewater (25%, 50%, 75% and 100%) and was found in a range of 8.1-14 μg ml(-1) day(-1). Growth study revealed that alga potentially grows up to 75% concentrated textile wastewater and reduces phosphate, nitrate and BOD by 87%, 82% and 63% respectively. Methylene blue dye (MB) removal was also observed by using dry and wet algal biomass harvested after phycoremediation. Adsorption isotherms (Langmuir and Freundlich) and kinetic models (pseudo first and second order) were applied on adsorption process. Dry algal biomass (DAB) was found more efficient biosorbent with large surface area and showed high binding affinity for MB dye in compare to wet algal biomass (WAB). The RL value for both biosorbent showed feasible adsorption process as the obtained value was between 0 and 1. Pseudo second order kinetic model with high degree of correlation coefficient and low sum of error squares (SSE %) value was found more suitable for representation of adsorption process in case of both biosorbents, however pseudo first order also showed high degree of correlation for both biosorbents.

    Previous studies have suggested increased risks of colorectal cancers among textile industry workers, potentially related to synthetic fibers. To investigate risks of colon and rectum cancers in relation to these and other textile industry exposures, we conducted a case-cohort study nested within a cohort study of female employees from the Shanghai Textile Industry Bureau (STIB). Cox proportional hazard regression modeling was used to estimate hazard ratios (HR) for colon and rectum cancers associated with duration of employment (e.g., 0, >0 to or =20 years) in various jobs classified according to process type and exposures to specific agents. Our findings indicate that certain long term exposures may pose increased risk of colorectal cancers, especially dyes and dye intermediates with colon cancer (> or =20 years exposure versus never, HR=3.9; 95% CI: 1.4-10.6), and maintenance occupation (HR = 2.3; 95% CI: 1.0-5.7) and metals exposure (HR = 2.0; 95% CI: 1.1-3.6) with rectum cancer. A decreased risk of rectum cancer was associated with exposure to natural fibers such as cotton (HR = 0.7; 95% CI: 0.5-0.9), and a trend of decreasing rectum cancer incidence was observed by category of cumulative quantitative cotton dust or endotoxin exposures, when exposures were lagged by 20 years.

    2016-06-01

    Full Text Available This paper discusses the presence of materials, technical and technological knowledge originating in the African culture in surface and textile construction work through the analysis of geometric patterns and their compositions derived, present in work with the quilt technique. This relationship is discussed from the perspective of geometry and the textile surface design showing how reflection on the ethnic and cultural diversity can contribute to the affirmation and appreciation of certain crops and their knowledge that, in many instances, are rootless and wrongly attributed the European and euro descendants cultures. This paper seeks to highlight the African origin of some geometric patterns lavishly designed in textile surfaces, often played, taught and disseminated without their proper provenances are granted. This reflection will demonstrate the contributions of African culture and African descent in the textile surface design, legitimizing the systematization of knowledge and African knowledge that can be understood through the study of its artifacts.

  12. Energy-Efficiency Improvement Opportunities for the Textile Industry

    Energy Technology Data Exchange (ETDEWEB)

    China Energy Group; Hasanbeigi, Ali

    2010-09-29

    The textile industry is one of the most complicated manufacturing industries because it is a fragmented and heterogeneous sector dominated by small and medium enterprises (SMEs). Energy is one of the main cost factors in the textile industry. Especially in times of high energy price volatility, improving energy efficiency should be a primary concern for textile plants. There are various energy-efficiency opportunities that exist in every textile plant, many of which are cost-effective. However, even cost-effective options often are not implemented in textile plants mostly because of limited information on how to implement energy-efficiency measures, especially given the fact that a majority of textile plants are categorized as SMEs and hence they have limited resources to acquire this information. Know-how on energy-efficiency technologies and practices should, therefore, be prepared and disseminated to textile plants. This guidebook provides information on energy-efficiency technologies and measures applicable to the textile industry. The guidebook includes case studies from textile plants around the world and includes energy savings and cost information when available. First, the guidebook gives a brief overview of the textile industry around the world, with an explanation of major textile processes. An analysis of the type and the share of energy used in different textile processes is also included in the guidebook. Subsequently, energy-efficiency improvement opportunities available within some of the major textile sub-sectors are given with a brief explanation of each measure. The conclusion includes a short section dedicated to highlighting a few emerging technologies in the textile industry as well as the potential for the use of renewable energy in the textile industry.

    In this paper we explore textile design activities and textile design management from an industrial network perspective. The textile industry is probably one of the most globalized manufacturing industries in the world and thus one of the most dispersed industries on the globe. Most studies...... on design management are framed inside the organisational context of the firm. In this study the role and practice of textile design is addressed in perspective of the global textile production network. The empirical data stems from six case studies exploring how different types of enterprises are organised...... in larger networks of suppliers, customers and other relations. Comparing the organisational networks we discuss how design activities unfold under different organisational settings. We also demonstrate that it is crucial for the companies who rely on external production facilities to have a strong design...

  14. Production and validation of model iron-tannate dyed textiles for use as historic textile substitutes in stabilisation treatment studies

    Directory of Open Access Journals (Sweden)

    Wilson Helen

    2012-05-01

    Full Text Available Abstract Background For millennia, iron-tannate dyes have been used to colour ceremonial and domestic objects shades of black, grey, or brown. Surviving iron-tannate dyed objects are part of our cultural heritage but their existence is threatened by the dye itself which can accelerate oxidation and acid hydrolysis of the substrate. This causes many iron-tannate dyed textiles to discolour and decrease in tensile strength and flexibility at a faster rate than equivalent undyed textiles. The current lack of suitable stabilisation treatments means that many historic iron-tannate dyed objects are rapidly crumbling to dust with the knowledge and value they hold being lost forever. This paper describes the production, characterisation, and validation of model iron-tannate dyed textiles as substitutes for historic iron-tannate dyed textiles in the development of stabilisation treatments. Spectrophotometry, surface pH, tensile testing, SEM-EDX, and XRF have been used to characterise the model textiles. Results On application to textiles, the model dyes imparted mid to dark blue-grey colouration, an immediate tensile strength loss of the textiles and an increase in surface acidity. The dyes introduced significant quantities of iron into the textiles which was distributed in the exterior and interior of the cotton, abaca, and silk fibres but only in the exterior of the wool fibres. As seen with historic iron-tannate dyed objects, the dyed cotton, abaca, and silk textiles lost tensile strength faster and more significantly than undyed equivalents during accelerated thermal ageing and all of the dyed model textiles, most notably the cotton, discoloured more than the undyed equivalents on ageing. Conclusions The abaca, cotton, and silk model textiles are judged to be suitable for use as substitutes for cultural heritage materials in the testing of stabilisation treatments.

    Fungal deterioration is one of the highest risk factors for damage of historical textile objects in Egypt. This paper represents both a study case about the fungal microflora deteriorating historical textiles in the Egyptian Museum and the Coptic museum in Cairo, and evaluation of the efficacy of several combinations of polymers with fungicides for the reinforcement of textiles and their prevention against fungal deterioration. Both cotton swab technique and biodeteriorated textile part technique were used for isolation of fungi from historical textile objects. The plate method with the manual key was used for identification of fungi. The results show that the most dominant fungi isolated from the tested textile samples belong to Alternaria, Aspergillus, Chaetomium, Penicillium and Trichoderma species. Microbiological testing was used for evaluating the usefulness of the suggested conservation materials (polymers combined with fungicides) in prevention of the fungal deterioration of ancient Egyptian textiles. Textile samples were treated with 4 selected polymers combined with two selected fungicides. Untreated and treated textile samples were deteriorated by 3 selected active fungal strains isolated from ancient Egyptian textiles. This study reports that most of the tested polymers combined with the tested fungicides prevented the fungal deterioration of textiles. Treatment of ancient textiles by suggested polymers combined with the suggested fungicides not only reinforces these textiles, but also prevents fungal deterioration and increases the durability of these textiles. The tested polymers without fungicides reduce the fungal deterioration of textiles but do not prevent it completely.

    2010-01-01

    Full Text Available Abstract Introduction Stasilon® is a novel hemostatic woven textile composed of allergen-free fibers of continuous filament fiberglass and bamboo yarn. The development of this product resulted from controlled in vitro thrombogenic analysis of an array of potentially hemostatic textile materials and it has been cleared for both external and internal use by the United States Food and Drug Administration for the arrest of hemorrhage. The goal of the study was to assess the hemostatic and adhesive properties of Stasilon® in the setting of life-threatening refractory hemorrhage. Case presentation A 39-year-old Caucasian man presented with severe necrotic pancreatitis that failed multiple aggressive attempts to control associated bleeding with electrocautery, suture ligation, and sequential anatomic packing with cotton-based sponges. Subsequent retroperitoneal packing with Stasilon® produced a non-adherent wound-dressing interface and resulted in the achievement of persistent hemostasis in the operative field. Conclusion In our patient, Stasilon® was demonstrated to be effective in the arrest of refractory hemorrhage.

  19. Textile Electrodes for EEG Recording — A Pilot Study

    2012-12-01

    Full Text Available The overall aim of our research is to develop a monitoring system for neonatal intensive care units. Long-term EEG monitoring in newborns require that the electrodes don’t harm the sensitive skin of the baby, an especially relevant feature for premature babies. Our approach to EEG monitoring is based on several electrodes distributed over the head of the baby, and since the weight of the head always will be on some of them, any type of hard electrode will inevitably cause a pressure-point that can irritate the skin. Therefore, we propose the use of soft conductive textiles as EEG electrodes, primarily for neonates, but also for other kinds of unobtrusive long-term monitoring. In this paper we have tested two types of textile electrodes on five healthy adults and compared them to standard high quality electrodes. The acquired signals were compared with respect to morphology, frequency distribution, spectral coherence, correlation and power line interference sensitivity, and the signals were found to be similar in most respects. The good measurement performance exhibited by the textile electrodes indicates that they are feasible candidates for EEG recording, opening the door for long-term EEG monitoring applications.

  20. A Study of Thermistor Performance within a Textile Structure

    Directory of Open Access Journals (Sweden)

    Theodore Hughes-Riley

    2017-08-01

    Full Text Available Textiles provide an ideal structure for embedding sensors for medical devices. Skin temperature measurement is one area in which a sensor textile could be particularly beneficial; pathological skin is normally very sensitive, making the comfort of anything placed on that skin paramount. Skin temperature is an important parameter to measure for a number of medical applications, including for the early detection of diabetic foot ulcer formation. To this end an electronic temperature-sensor yarn was developed by embedding a commercially available thermistor chip into the fibres of a yarn, which can be used to produce a textile or a garment. As part of this process a resin was used to encapsulate the thermistor. This protects the thermistor from mechanical and chemical stresses, and also allows the sensing yarn to be washed. Building off preliminary work, the behaviour and performance of an encapsulated thermistor has been characterised to determine the effect of encapsulation on the step response time and absolute temperature measurements. Over the temperature range of interest only a minimal effect was observed, with step response times varying between 0.01–0.35 s. A general solution is presented for the heat transfer coefficient compared to size of the micro-pod formed by the encapsulation of the thermistor. Finally, a prototype temperature-sensing sock was produced using a network of sensing yarns as a demonstrator of a system that could warn of impending ulcer formation in diabetic patients.

  2. Clusters and local development: the case of the textile district of Atuntaqui

    Directory of Open Access Journals (Sweden)

    César Paredes

    2013-09-01

    Full Text Available Atuntaqui is heralded as a local economic development success story. The author scrutinizes the experience of the textile industrial district in Atuntaqui in the province of Imbabura, and concludes that the district actually represents a case of overspecialization, given a lack of economic diversification. Moreover the author notes that the municipality has an urban bias, pointing out the need for a broader ¨territorial¨ approach to local and regional development planning that factors in issues like water scarcity, rural poverty and exploitation of female labour, as opposed to the current myopic view that ignores rural urban linkages. In the article the success story of Atuntaqui is downplayed, stating that donors exaggerated the economic impact of the textile cluster.Atuntaqui is viewed as a model by neighboring cities as a result of its recent economic dynamism. Local policy makers need to look deeper into these efforts, and also take into account negative externalities, concluding that clusters are not a panacea for quick industrial development.

    Treatment of textile dye wastewater was carried using Pleurotus floridanus in a batch reactor. Response surface methodology (RSM) was used to optimize the process parameters like pH, temperature, agitation speed and dye wastewater concentration for the decolorization of textile dye wastewater. The optimum conditions for the maximum decolorization was: pH 6.6, temperature 28.8 °C, agitation speed 183 rpm and dye wastewater concentration 1:2. From the results it was found that, the linear effect of agitation speed and initial textile dye wastewater concentration were more significant than other factors for the textile dye wastewater treatment. At these optimized conditions, the maximum decolorization and COD reduction was found to be 71.2 and 80.5 %, respectively. Kinetics of textile dye degradation process was studied by various models like first order, diffusional and Singh model. From the results it was found that the degradation follows first order model with R 2 value of 0.9550.

    2016-05-01

    Full Text Available Flame retardants (FRs have been around us for decades to increase the chances of survival against fire or flame by limiting its propagation. The FR textiles, irrespective of their atmospheric presence are used in baby clothing, pushchairs, car seats, etc. The overall FR market in Asia, Europe, and the United States in 2007 was around 1.8 million metric tonnes. It is estimated that the worldwide consumption of FRs will reach 2.8 million tonnes in 2018. Unfortunately, a sustainable approach for textile waste, especially in the case of FR textiles, is absent. Incineration and landfill of FR textiles are hindered by various toxic outcomes. To address the need for sustainable methods of discarding FR textiles, the mechanical recycling of cotton curtains was evaluated.

    Full Text Available Allergic contact dermatitis to textile dyes is considered to be a rare phenomenon. A recent review reported a prevalence of contact allergy to disperse dyes between 0.4 and 6.7%. The relevance of positive patch testing was not reported in all studies. Textile dye allergy is easily overlooked and is furthermore challenging to investigate as textile dyes are not labelled on clothing. In this report, we present a case of allergic contact dermatitis to a textile necklace. The patch test showed strong reactions to the necklace and the azo dyes Disperse Orange 1 and Disperse Yellow 3. Despite the European legislation and the reduced use of disperse dyes in Third World countries, disperse azo dyes still induce new cases of allergic contact dermatitis.

    Full Text Available This experimental investigation studies the benefits of reinforcing the various sub grade soils in flexible pavement. Three types of soils A, B and C and a particular type of Jute geo textile material were selected for the study. Fundamental properties of soils like specific gravity, liquid limit, plastic limit and optimum moisture content were determined on unreinforced soils; California Bearing Ratio (CBR test and Unconfined Compression (UCC Strength test were also conducted on unreinforced and reinforced soils. The optimum quantity of jute geo textile was arrived based on the results from CBR test, other parameters such as modulus of elasticity and failure stress were ascertained from the results of UCC test. Using the optimum geo textile content, the thickness of pavement required over the three types of sub grade soils with and without reinforcement was determined based on the guidelines specified in IRC 37-2001. A comparative analysis was carried out to identify the economy in the material due to the effect of reinforcing the soils with jute geo textile. Subsequently cost benefit analysis of reinforced and unreinforced pavement was also done to ascertain the economic viability of fibre material. From the result analysis it was observed there is a significant material save of about 25% per every km of pavement

    2009-10-15

    The influence of several factors in the simultaneous photocatalytic degradation of three textile dyes - Acid Red 97, Acid Orange 61 and Acid Brown 425 - has been studied using a fractional factorial design 2(5-1). The considered factors were: the initial concentration of each dye, the catalyst concentration (TiO(2)) and pH. First, we developed a rapid analytical methodology based on recording UV-visible spectra during the degradation process and a data treatment using multivariate curve resolution with alternating least squares (MCR-ALS), which enabled the three dyes to be quantified simultaneously despite the overlap of their spectra. The kinetic constant of degradation for each dye in all the experiments was evaluated. In all cases the degradation followed a first order kinetics. For a significance level of 5%, the most important factor in the photodegradation of each dye is the concentration of Acid Red 97, the degradation is more effective at higher pHs and, in the studied range, the concentration of the catalyst is not important.

    Full Text Available This paper discusses industrial heritage, i.e. the society‘s relationship with the rem-nants of defunct industrial infrastructure. We demonstrate the issues involved on the example of Brno, one of the key economic centers of the Czech lands. Brno owes this status to its early industrialization, especially the textile industry which dominated its economic landscape from the late 1700s. Early 1990s saw the total collapse of the industry which resulted, inter alia, in the city‘s landscape being dotted by abandoned, defunct and derelict industrial buildings and building complexes. Those are now viewed as impediments to city‘s development and the city is looking for new ways to utilize them. These effort have been somewhat successful, for example in revitalizing a number of brownfields, but a large-scale solutions is still a desidera-tum. As a result, a number of building with great historical and cultural value have been torn down, including the industrial site of Vlněna, one of the icons of the textile industry in Brno, which was demolished in 2016. A unique opportunity to preserve, transform and revitalize this unique complex of buildings with immense historical value was wasted and thus a significant part of the industrial identity of Brno was irrevocably lost.

    Full Text Available Nanomaterial and its application in textiles are emerging as vast and diverse field due to enhanced functionalized characteristics. This study emphasizes the fabrication of tungsten trioxide nanostructured rods and analyzes its electrostatic and ultraviolet resistance properties. These nanorods are synthesized by hydrothermal method. Through hydrothermal method rod like nanostructures were grown on polyester fabric as it withstands curing temperature easily. The growth mechanism of the film is investigated. Electrostatic analysis of treated polyester fabric was failed but the analysis of seeded solution revealed that it has tunable transmittance modulation under different voltages and repetitive cyclic between the clear and blue states. Ultraviolet resistance of 100% seeded polyester fabric was higher than untreated fabric with respect to increasing concentration of nanorods. Results show that although the seeded solution is perfect, the conductivity of tungsten trioxide cannot be achieved on textiles.

    In this study, the residual strength of sisal textile reinforced vinyl ester resin is studied using specimens with a central hole. Two kinds of chemicals, silane and permanganate, are used to treat sisal fibre surfaces. The effects of fibre surface treatments on the residual strength of sisal fibre reinforced composites with different central hole sizes are analysed. Optical microscopy (OM) surveys provide sound evidence for the relationship between residual strength properties and fracture morphologies of sisal textile reinforced vinyl ester.Several theoretical models used to predict the residual strength of laminated composites are briefly reviewed. Point stress criterion (PSC) and average stress criterion (ASC) models are used to analyze the mechanical properties of sisal textile reinforced polymers with a central hole in this research. Material constant, characteristic length (do or lc), is obtained and used to analyze the mechanical behavior of the composites. The residual strength of the composites predicted by PSC and ASC models is in good agreement with the experimental results..

    The biosorption of orange solimax TGL 182% (OS-TGL) textile dye onto new and low cost biossorbent (malt bagasse) in aqueous solutions was investigated. The malt bagasse was characterized by Fourier transform infrared spectroscopy and specific surface area (BET method).Batch biosorption experiments were conducted in order to determine the following parameters: particles size, pH, agitation speed, temperature, contact time, biomass dosage, influence of the ionic strength and, finally, the influence of other textile dye on the OS-TGL biosorption. The optimum conditions for OS-TGL removal were obtained at pH 1.5, agitation speed of 150rpm, contact time of 180min and biomass dosage 2, 8gL(-1). The results show that the kinetics of biosorption followed a pseudo-second-order model and by increasing the temperature from 293 up to 313K, the biosorption capacity was improved. The Langmuir model showed better fit and the estimated biosorption capacity was 23.2mgg(-1). The negative values of Gibbs free energy, ΔG°, and positive value of enthalpy, ΔH°, confirm the spontaneous nature and endothermic character of the biosorption process. The results of the ionic strength effect indicated that the biosorption process under study had a strong tolerance in high salt concentrations. The removal capacity (>95%) was not affected with the presence of other textile dyes.

    Full Text Available This article discusses the profile of the remaining textile industry workforce as a strategic factor for the building of competencies in the companies of the sector. It investigates the impact of the cultural and identitarian traits developed by the workforce within century-old organizations on productive dynamics. The discussion is justified in a precarious working context seeking competitive differentials. The theoretical framework is supported by a reflexive axis that gives first priority to the combination of complementary topics. This article is based on exploratory and qualitative research developed through a multiple case methodology (Yin, 2005 covering textile factions and cotton mills from the micro-regions of Curvelo and Diamantina, Minas Gerais State. The body of the work included fifty-one operating and directive-level respondents and the data were collected through interviews between October 2009 and March 2010. The NVIVO software and Content Analysis were used for data processing based on categories and frequency counting (Bardin, 1979. The results indicate that from a structural viewpoint, the retention of a qualified workforce, both technically and skillfully, was an alternative to the shaping of the workforce and the stabilization of the productive process. Concerning the relational and formative dimensions, the study concluded that learning developed fundamentally by means of experienced tutors. Competence building resulted from some deliberate strategy consisting of social and historical aspects within the work environment.

    Common materials have Poisson's ratio values ranging from 0.0 to 0.5. Auxetic materials exhibit negative Poisson's ratio. They expand laterally when stretched longitudinally and contract laterally when compressed. In recent years the use of textile technology to fabricate auxetic materials has attracted more and more attention. It is reflected in the extent of available research work exploring the auxetic potential of various textile structures and subsequent increase in the number of research papers published. Generally there are two approaches to producing auxetic textiles. The first one includes the use of auxetic fibers to produce an auxetic textile structure, whereas the other utilizes conventional fibres to produce a textile structure with auxetic properties. This review deals with auxetic materials in general and in the specific context of auxetic polymers, auxetic fibers, and auxetic textile structures made from conventional fibers and knitted structures with auxetic potential.

    Based on the participant observation of a textile corporation in the south of Jiangsu province,it is disclosed that migrant workers consent to work overtime is contributed to a skillful and concealed forced labor mechanism with hegemonic regime instead of despotic regime as usual think-ing,which includes the wage system and hypocritical piecework system.Firstly,the price of the piece is completely determined by the factory;secondly,it is the"unfixed price","unfixed production"and"fixed salary"strategy;thirdly,fuzziness and closure operation of the piece also works.This is the re-sult of gaming between the Chinese government and labor and the global capitals,which leads to the vertical and horizontal division of China's labor market.In the perspective of vertical line,the labor are divided into"old man"under the old system and"new man"in the market.In the perspective of hori-zontal line,local workers and migrant workers are divided into the"primary"and"secondary"in the labor market based on their different household registration.The empowerment theory supplies a pos-sible solution to this problem.%经过对苏南一家纺织工厂的观察、访谈发现,工人自愿性超长时间加班并不是工厂直接强制劳动的结果,而是在深富霸权性格的工厂体制里推行的一种更巧妙更隐秘的强制劳动---精心设计的薪酬制度、虚有其名的计件制。具体体现为计件的价格完全由工厂决定,工厂实施一种“浮动价格”、“浮动产量”与“固定工资”相关联的策略,计件工资操作的模糊性和封闭性。中国政府、劳工与全球资本利益博弈的结果,造就了当下中国特殊的横向和纵向分割的二元劳动力市场,从纵向“工龄”角度分割为旧体制下的“老人”和市场体制下的“新人”,从横向户籍身份分割为本地劳工和外地劳工。以赋权为核心的“行动社会学”为解决这一困境提供了方向。

    2017-03-01

    In the present study, the electrochemical oxidation of real wastewaters discharged by textile industry was carried out using a boron-doped diamond (BDD) anode. The effect of operational variables, such as applied current density (20-100 mA·cm(-2)), NaCl concentration added to the real wastewaters (0-3 g·L(-1)), and pH value (2.0-10.0), on the kinetics of COD oxidation and on the energy consumption was carefully investigated. The obtained experimental results could be well matched with a proposed kinetic model, in which the indirect oxidation mediated by electrogenerated strong oxidants would be described through a pseudo-first-order kinetic constant k. Values of k exhibited a linear increase with increasing applied current density and decreasing pH value, and an exponential increase with NaCl concentration. Furthermore, high oxidation kinetics resulted in low specific energy consumption, but this conclusion was not suitable to the results obtained under different applied current density. Under the optimum operational conditions, it only took 3 h to complete remove the COD in the real textile wastewaters and the specific energy consumption could be as low as 11.12 kWh·kg(-1) COD. The obtained results, low energy consumption and short electrolysis time, allowed to conclude that the electrochemical oxidation based on BDD anodes would have practical industrial application for the treatment of real textile wastewater.

  19. Textile Supercapacitors

    Jost, Kristy Alana

    Innovative and interdisciplinary solutions to wearable textile energy storage are explored as power sources for wearable electronics and smart textiles. Due to their long cycle life, non-toxic and inexpensive materials, supercapacitors were converted into textiles. Textile supercapacitors were developed using scalable fabrication methods including screen-printing, yarn making, and 3D computerized knitting. The electrode materials reported in this thesis undergo thorough electrochemical analysis, and are capable of storing up to 0.5 F/cm2 which is on par with conventionally solid supercapacitors (0.6 F/cm2). Capacitive yarns are capable of storing up to 37 mF/cm and are shown to be knittable on industrial knitting equipment. Both are some of the highest reported capacitance for all-carbon systems in the field. Yet both are the only systems composed of inexpensive and non-toxic activated carbon, the most commonly used electrode material used in supercapacitors, opposed to carbon nanotubes or graphene, which are typically more 10-100 times more expensive. However, all of the fabrication techniques reported here are also capable of incorporating a wide variety of materials, ultimately broadening the applications of textile energy storage as a whole. Fully machine knitted supercapacitors are also explored and electrochemically characterized in order to determine how the textile structure affects the capacitance. In conclusion, a wide variety of fabrication techniques for making textile supercapacitors were successfully explored.

  20. Testing for divergent transmission histories among cultural characters: a study using Bayesian phylogenetic methods and Iranian tribal textile data.

    Archaeologists and anthropologists have long recognized that different cultural complexes may have distinct descent histories, but they have lacked analytical techniques capable of easily identifying such incongruence. Here, we show how bayesian phylogenetic analysis can be used to identify incongruent cultural histories. We employ the approach to investigate Iranian tribal textile traditions. We used bayes factor comparisons in a phylogenetic framework to test two models of cultural evolution: the hierarchically integrated system hypothesis and the multiple coherent units hypothesis. In the hierarchically integrated system hypothesis, a core tradition of characters evolves through descent with modification and characters peripheral to the core are exchanged among contemporaneous populations. In the multiple coherent units hypothesis, a core tradition does not exist. Rather, there are several cultural units consisting of sets of characters that have different histories of descent. For the Iranian textiles, the bayesian phylogenetic analyses supported the multiple coherent units hypothesis over the hierarchically integrated system hypothesis. Our analyses suggest that pile-weave designs represent a distinct cultural unit that has a different phylogenetic history compared to other textile characters. The results from the Iranian textiles are consistent with the available ethnographic evidence, which suggests that the commercial rug market has influenced pile-rug designs but not the techniques or designs incorporated in the other textiles produced by the tribes. We anticipate that bayesian phylogenetic tests for inferring cultural units will be of great value for researchers interested in studying the evolution of cultural traits including language, behavior, and material culture.

    Reactive Red 183, Reactive Red 2 and Reactive Blue 204 (red dye, green dye and blue dye) are three reactive dyes frequently used in textile industry. In some atmospheric conditions ( high temperature, perspiration, pH values, UV/IR radiations), some quantities of these hydrolyzed dyes, could pass from textile clothes directly into the human skin. There were used 4 groups of white Swiss mice (with similar weight and number of both sexes), control group and 3 groups, treated once daily with a retro-auricular application of different reactive dyes. After 14 days of treatment, blood samples were taken from retro-orbitary plexus to assess leukocyte count, phagocytic capacity of peripheral neutrophils, serum opsonic capacity, phagocyte capacity and bactericidal capacity of peritoneal macrophages, splenic T lymphocytes with rossetting capacity and spleen cells forming Jerne plaques. The retro-acuricular and latero-cervical nodes were weighted. Red dye did not influence the weight of the studied nodes, but determined statistically significant modifications on non-specific immune system parameters. Blue and grena dyes determined modifications of weight especially of retroauricular nodes. Grena dye determined important effects of non-specific immune system parameters (serum opsonic capacity, phagocyte capacity and bactericidal capacity of peritoneal macrophages). The blue dye did not determine a biological response. Red and green dye determined important effects on non-specific immune system parameters.

    Full Text Available In this work, sequential batch reactor (SBR was employed for the treatment of textile dye wastewater. The performance of four white rot fungi (WRF viz. Coriolus versicolor, Pleurotus floridanus, Ganoderma lucidum and Trametes pubescens was evaluated in pure and mixed combinations in terms of decolorization. From the results it was found that the combination of Pleurotus floridanus, Ganoderma lucidum and Trametes pubescens was best and they were used in the SBR. The process parameters like air flow rate, sludge retention time (SRT and cycle period were optimized using response surface methodology (RSM. At these optimized conditions, treatment of textile dye wastewater was carried out at various initial dye wastewater concentration and hydraulic retention time. The performance of SBR was analyzed in terms of decolorization, COD reduction and sludge volume index (SVI. From the results it was found that a maximum decolorization and COD reduction of 71.3% and 79.4%, respectively, was achieved in the SBR at an organic loading rate of 0.165 KgCOD/m3 d. The sludge volume index (SVI was found to be low in the range of 90–103 mL/g. The kinetic study was carried out using a first order based model and the degradation follows the first order system.

    Textile effluents are highly toxic as they contain a large number of metal complex dyes. The high concentration of such dyes causes many water borne diseases and increases the BOD of the receiving waters. On the other hand, flyash is a major pollutant generated in coal-based thermal power plants and has potentiality for use as an adsorbent. In the present work, adsorption studies were made in treating the dye solutions of methylene blue and Congo red textile dyes by using flyash. Effects of quantity of adsorbent, time of contact, initial effluent concentration, pH and temperature have been investigated experimentally and the results were compared with those obtained by using activated carbon. The first-order adsorption rate constants were determined and found decreasing with temperature. The results obtained were fitted by Langmuir model since monolayer formation observed. Also, Langmuir adsorption isotherm parameters were estimated from the experimental data obtained for both methylene blue and Congo red dyes using both the adsorbents.

    Life cycle analysis (LCA) is a technique that analyses the life cycle of a product process or activity in an attempt to identify its overall environmental impact. This approach can be of great help in strategic or operational decision-making in industry or business. This article takes as an example a comparative study of systems for treating strongly coloured industrial effluent. To this end, two well established technologies for dealing with industrial waste were examined: a) the physico-chemical treatment of effluents by coagulation-flocculation: b) a process combining physico-chemical treatment and biological aerobic activated sludge treatment. In addition, the viability of an emerging technology based on the decolouring of effluents with ligninolytic fungi was considered, although this process is still at the study stage.

    With the goal of finding novel biocompatible materials suitable to replace silver in the manufacturing of textile electrodes for medical applications of electrical bioimpedance spectroscopy, three different polymeric materials have been investigated. Films have been prepared from different polymeric materials and custom bracelets have been confectioned with them. Tetrapolar total right side electrical bioimpedance spectroscopy (EBIS) measurements have been performed with polymer and with standard gel electrodes. The performance of the polymer films was compared against the performance of the gel electrodes. The results indicated that only the polypropylene 1380 could produce EBIS measurements but remarkably tainted with high frequency artefacts. The influence of the electrode mismatch, stray capacitances and large electrode polarization impedance are unclear and they need to be clarified with further studies. If sensorized garments could be made with such biocompatible polymeric materials the burden of considering textrodes class III devices could be avoided.

    The potential of Penicillium chrysogenum to decolorize azo dyes and a real industrial textile wastewater was studied. P. chrysogenum was able to decolorize and degrade three azo dyes (200 mg L(-1)), either independently or in a mixture of them, using glucose as a carbon source. A kinetic model for degradation was developed and it allowed predicting the degradation kinetics of the mixture of the three azo dyes. In addition, P. chrysogenum was able to decolorize real industrial wastewater. The kinetic model proposed was also able to predict the decolorization of the real wastewater. The calibration of the proposed model makes it a useful tool for future wastewater facilities' design and for practical applications.

    Outsourcing and job losses to countries with lower wage costs are common to many Western countries, and are issues of great public concern due to their economic and social impact. This paper looks at the impact on labor of a dramatic change in the Danish textile and clothing (T&C) industry, causing...... large reductions in the total level of the employment. This development, which is well known in most Western countries, is characterized by strict rationalization and outsourcing strategies, but has been of a larger magnitude in Denmark than in many other places. In this connection, one would expect...... a major increase in unemployment among former T&C workers. To address this issue we follow each individual worker employed in the T&C industry and seek to answer the question whether transitions into unemployment are higher than the manufacturing industry average. Contrary to expectations we find...

    Full Text Available Unconventional textiles are manufactured different from those obtained by the classic spinning weaving and knitting. They are obtained by mechanical or chemical consolidation of a textile backing up of fibrous layers or combinations of layers of fiber and yarn, fabrics and yarns, fabrics or knitted fabrics and fibers. The non-conventional textiles can be obtained by mechanical or chemical consolidation of a system or several systems of wires. The increasing trend of chemical fiber production compared to natural fibers found also in the unconventional fabrics. In addition emphasis is laid increasingly on the use of recyclable materials recovered fibers and preforms or debris resulting from a regular textile processing. Processing unconventional fibers that are recovered from such materials are best suited for the production of unconventional textile. The production of unconventional textile fiber made from layers have the largest share. The fiber layers may have fibers oriented in a single direction, in two or more directions. The fiber layers can enhance mechanical, chemical and mixed. This produces textile auxiliaries for clothing, replacement canvas for buckram wadding, sanitary ware carpet filters, support for synthetic leather, cloth, wallpapers.

    Full Text Available The process was investigated in a textile dying unit and subsequently wastewater generation profile was studied for the development of a viable treatment. The dyeing unit under the study generated a considerable volume of wastewater containing inorganic chemicals and organic reactive green dye. Chemical oxygen demand (COD resulting from all the chemically oxidizible substances and the residual color of the dye were targeted for removal. The wastewater samples were collected from different sub-processes and then characterized for the parameters viz. pH, Total solid, Suspended solid, Dissolved solid, COD and Alkalinity. A composite wastewater sample was prepared according to the measured wastewater discharge from various unit operations and used for treatability study. In the first stage, coagulation-flocculation with alum and chemical oxidation with bleaching powder were performed separately. Subsequently, adsorption study was conducted with crushed burnt coal (C.B.C. on the composite wastewater, initially treated with 10% bleaching powder solution. After several trials, this combination was found to be effective for a C.B.C. content of 10% under a contact period of 90 minutes, which showed 100% colour and about 95% COD removal.

    According to new economic geography, this paper analyzes the changes of centripetal and centrifugal forces from the view of influencing factors using static and dynamic methods. The resultant force of centripetal and centrifugal forces in different regions is different, the driving force of industrial transfer comes from comparative advantage of the resultant force. TFP (total factor productivity) is the substitution variables of the resultant force. Technology, institutional, specialized mode and innovation factors are influencing factors of TFP, the flow rate of the influencing factors is faster than the labor mobility. The ratio of capital to labor is relatively stable, the speed of labor mobility restricts the productivity of the production portfolio, the adjustment speed of the production factor productivity lags behind TFP adjustment speed. Therefore, we draw an important conclusion: The decision basis for spatial location selection is based on TFP changes rather than changes of resource allocation efficiency. On the statistics data of China's manufacturing enterprises in 2001 - 2009, we use a semi-parametric estimation method to measure TFP. Through a deeply TFP comparative analysis between textile industries and other industries in China's eastern, central and western regions, we find that the intrinsic motivation of China's textile industry from the east to the Midwest has been appeared in 2001 and strengthened year by year from 2001 to 2007. In fact, contrary to the direction of the intrinsic dynamic action, in 2001 -2007 textile industries transfer is from the Midwest to the east, spatial allocation efficiency of production factors is rising. In 2007 - 2009 textile industries transfer is from the east to the Midwest, spatial allocation efficiency of production factors shows a downward trend from 2007 to 2009. Further studies show that: China's textile industry transfer of the inverse driving force in 2001 -2007, lose the opportunity to

  4. Polyester Textiles as a Source of Microplastics from Households: A Mechanistic Study to Understand Microfiber Release During Washing.

    Microplastic fibers make up a large proportion of microplastics found in the environment, especially in urban areas. There is good reason to consider synthetic textiles a major source of microplastic fibers, and it will not diminish since the use of synthetic fabrics, especially polyester, continues to increase. In this study we provide quantitative data regarding the size and mass of microplastic fibers released from synthetic (polyester) textiles during simulated home washing under controlled laboratory conditions. Consideration of fabric structure and washing conditions (use of detergents, temperature, wash duration, and sequential washings) allowed us to study the propensity of fiber shedding in a mechanistic way. Thousands of individual fibers were measured (number, length) from each wash solution to provide a robust data set on which to draw conclusions. Among all the variables tested, the use of detergent appeared to affect the total mass of fibers released the most, yet the detergent composition (liquid or powder) or overdosing of detergent did not significantly influence microplastic release. Despite different release quantities due to the addition of a surfactant (approximately 0.025 and 0.1 mg fibers/g textile washed, without and with detergent, respectively), the overall microplastic fiber length profile remained similar regardless of wash condition or fabric structure, with the vast majority of fibers ranging between 100 and 800 μm in length irrespective of wash cycle number. This indicates that the fiber staple length and/or debris encapsulated inside the fabric from the yarn spinning could be directly responsible for releasing stray fibers. This study serves as a first look toward understanding the physical properties of the textile itself to better understand the mechanisms of fiber shedding in the context of microplastic fiber release into laundry wash water.

    Graphical abstract: - Highlights: • A phytoreactor was developed and augmented with immobilized bacteria. • This consortium showed enhanced treatment than the individual species. • Oxido-reductases from P. crinitum and B. pumilus could decolorize the effluent. • Characterization of effluent samples endorsed the efficacy of consortial strategy. • Toxicity studies revealed the less toxic nature of the consortium treated effluent. - Abstract: A static hydroponic bioreactor using nursery grown plants of Pogonatherum crinitum along with immobilized Bacillus pumilus cells was developed for the treatment of textile wastewater. Independent reactors with plants and immobilized cells were also kept for performance and efficacy evaluation. The effluent samples characterized before and after their treatment showed that the plant–bacterial consortium reactor was more efficient than those of individual plant and bacterium reactors. COD, BOD, ADMI, conductivity, turbidity, TDS and TSS of the textile effluent was found to be reduced by 78, 70, 93, 4, 90, 13 and 70% respectively within 12 d by the consortial set. HPTLC analysis revealed the transformation of the textile effluent to new products. The phytotoxicity study on Phaeseolus mungo and Sorghum vulgare seeds showed reduced toxicity of treated effluents. The animal toxicity study performed on Etheostoma olmstedi fishes showed the toxic nature of untreated effluent giving extreme stress to fishes leading to death. Histology of fish gills exposed to treated effluent was found to be less affected. The oxidative stress related enzymes like superoxide dismutase and catalase were found to show decreased activities and less lipid peroxidation in fishes exposed to treated effluent.

  9. Performance Study of Screen-Printed Textile Antennas after Repeated Washing

    Directory of Open Access Journals (Sweden)

    Kazani I.

    2014-06-01

    Full Text Available The stability of wearable textile antennas after 20 reference washing cycles was evaluated by measuring the reflection coefficient of different antenna prototypes. The prototypes’ conductive parts were screen-printed on several textile substrates using two different silver-based conductive inks. The necessity of coating the antennas with a thermoplastic polyurethane (TPU coating was investigated by comparing coated with uncoated antennas. It is shown that covering the antennas with the TPU layer not only protects the screen-printed conductive area but also prevents delamination of the multilayered textile fabric substrates, making the antennas washable for up to 20 cycles. Furthermore, it is proven that coating is not necessary for maintaining antenna operation and this up to 20 washing cycles. However, connector detachment caused by friction during the washing process was the main problem of antenna performance degradation. Hence, other flexible, durable methods should be developed for establishing a stable electrical connection.

  10. Study on Treatability of Real Textile Wastewater by Electrochemically Generated  Fenton Reagent using Graphite Felt Cathode

    Directory of Open Access Journals (Sweden)

    Akbar Eslami

    2012-10-01

    Full Text Available Background and Objectives: Electro-Fenton process has been widely applied for dye removal from aqueous solution lately. Fenton's reagent is formed in the electrolysis medium through the simultaneous electrochemical reduction of O2 and Fe3+ to H2O2 and Fe2+ respectively on the cathode surface. In this paper, COD reduction potential and decolorization of real textile wastewater were evaluated by electrochemically generated Fenton reagent process. This wastewater mainly contains non-biodegradable acidic dyes, which are highly resistant against conventional oxidizing agents.Materials and Methods: Electro-Fenton process was carried out in an open and undivided cell in order to evaluate the removal of color and COD from real textile wastewater using graphite felt (cathode and Pt plate (anode at room temperature. The effects of current density, flow rate of air, electrolysis time, initial pH, and ferrous ion concentration were investigated for real textile wastewater.Results: The results showed that the optimal experimental conditions obtained in electrochemical studies were as follows: current density=4.8 mA cm-2, pH=3, flow rate of air=1.5L/min, Fe2+=3mM and reaction time=160 min. Under these conditions, COD removal and decolorization achieved were 63% and 77.2% respectively. Conclusion: According to the results achieved, electro-Fenton process can be used as a pretreatment for degradation of colored wastewater and refractory pollutants. Moreover, this feasible technology improves biodegradability of the textile wastewater.

    Textiles are a valuable source of forensic evidence and the nature and condition of textiles collected from a crime scene can assist investigators in determining the nature of the death and aid in the identification of the victim. Until now, much of the knowledge of textile degradation in forensic contexts has been based on the visual inspection of material collected from soil environments. The purpose of the current study was to investigate the potential of a more quantitative approach to the understanding of forensic textile degradation through the application of infrared spectroscopy. Degradation patterns of natural and synthetic textile materials as they were subjected to a natural outdoor environment in Australia were investigated. Cotton, polyester and polyester - cotton blend textiles were placed on a soil surface during the summer and winter seasons and were analysed over periods 1 and 1.5 years, respectively, and examined using attenuated total reflectance (ATR) spectroscopy. Statistical analysis of the spectral data obtained for the cotton material correlated with visual degradation and a difference in the onset of degradation between the summer and winter season was revealed. The synthetic material did not show any signs of degradation either visually or statistically throughout the experimental period and highlighted the importance of material type in terms of preservation. The cotton section from the polyester - cotton blend samples was found to behave in a similar manner to that of the 100% cotton samples, however principal component analysis (PCA) demonstrated that the degradation patterns were less distinct in both the summer and winter trial for the blend samples. These findings indicated that the presence of the synthetic material may have inhibited the degradation of the natural material. The use of statistics to analyse the spectral data obtained for textiles of forensic interest provides a better foundation for the interpretation of the data

  12. Novel antimicrobial textiles

    2003-10-01

    Many microorganisms can survive, and perhaps proliferate on textiles, generating adverse effects such as: disease transmission, odor generation, pH changes, staining, discoloration and loss of performance. These adverse effects may threaten users' health, deteriorate textile properties and degrade service quality. It may, therefore, be desirable to incorporate antimicrobials on textiles for controlling the growth of microorganisms. This dissertation focuses on the development of antimicrobial fibers and fabrics by integration of antimicrobials with these textiles. The applications of hydantoin-based halamines were mainly investigated in the research. The typical process is that hydantoin containing compounds are grafted onto textiles and transformed to halamine by chlorination. Hydantoin-based halamines are usually chloramines that release chlorine (Cl+) via cleavage of the -NCl functional group which attacks and kills microbes. The antimicrobial behavior is rechargeable many times by rinsing the fiber or fabric with chlorine-containing solution. Some quaternary ammonium type antimicrobials were also investigated in this research. The choice of integrating techniques is dependant on both the textile and antimicrobial compounds. In this dissertation, the nine approaches were studied for incorporating antimicrobial with various textiles: (1) co-extrusion of fibers with halamine precursor additive; (2) grafting of the quaternary ammonium compounds onto ethylene-co-acrylic acid fiber for creating quaternary ammonium type antimicrobial fiber; (3) entrapment of the additives in thermally bonded bicomponent nonwoven fabrics; (4) attaching antimicrobial additives to surfaces with latex adhesive coating; (5) grafting of antimicrobial compounds onto rubber latex via UV exposure; (6) reaction of halamine with needle-punched melamine formaldehyde nonwoven fabric and laminates; (7) coating melamine resin onto tent fabrics and laminates; (8) synthesis of super absorbent polymer

    This study explores the effectiveness of factors such as industrial dynamic, resourcefulness and environ- mental attributes on industrial sustainable development capability from the viewpoint of population ecology theory. It uses the existing information from textile enterprises during the past five years (2004 -2008 ) as authentication samples. Important research discoveries include: Population density within the industry will indeed affect industrial sustainable development capability. In addition, seeking continuous operation, factories must pursue most appropri- ate scale according to industrial characteristics in order to obtain more resources to benefit industrial management. Furthermore, factories hoping to survive can not limit their consideration within internal organization factors. They also need to take environmental resources into account.%本研究扶生态理论分析产业动态、资源可获得性及井部环境条件等园素对产业可持续发展能力的影响作簿,以过去5年(2004-2008)中国纺织产业的季度经济数据作为实证样本。研究发现:产业内的种群密度确实会影响产业可持续发展能力;企业必须根据产韭特性选择最傀规模,藐取更多的资源以达到可持续发展;另外,企监为求生存不能仅考虑企业内部园紊,也要考虑环境资源条件等外部因素。

  14. Preliminary studies on mud stabilization / solidification, from textile laundry treatments, for re-utilization as building mortar

    Full Text Available The laundries and industrial dry cleaner's generate liquid effluents that, after treatment for matter in suspension floculation, produce sludge. This residue has varied chemical composition, due to the products used in the process. Such residue is considered inadequate for in natura disposition in the environment, and it should have, as final destination, an industrial landfill. In the studied case, such industrial landfill is not available and the residues are truck-driven for about 400 Km, causing a strong financial impact over the production of an emergent local textile industry market. This work presents the physical-chemical characterization of the sludge produced by an industrial laundry, studying its final disposition in the process of E/S addition in Portland cement, seeking its re-utilization in civil construction materials, to minimize this residue's final disposition costs. The analysis contemplated: COD total, fixed and volatile solids in the sludge, sludge density, pH and metals presence. The presence of the metals: Fe, Mg, Al, Sn, Ca, Cr, Co, Cu, Mn and Zn was detected in the sludge. The incorporation of this sludge in mortar was studied as residue final destination. Samples of this mortar were submitted to compression resistance analysis. Results demonstrate that the mortar with sludge contents lower than 25% in relation to the cement mass, after 28 days, shows mechanical resistance values larger than 10 Mpa, being fit to be used as civil construction secondary material, without structural function. Posterior studies will be necessary to evaluate the organic matter influence in the composite's durability.

    Full Text Available Problem statement: Business groups play significant roles and evolve with the changing institutional environments in many emerging Asian economies. A study of how the institutional transition and the resultant ‘institutionally rooted evolution’ of business groups affect the diversification outcomes of affiliated firms will therefore help to deepen our understanding of this unique organizational form. Approach: This study uses the 2001-2005 data on listed firms from the Chinese textile industry and estimates the diversification effects of all firms in the sample and the differences in the diversification effects between group-affiliated firms and their stand-alone counterparts. Results: A positive relationship is found between the listed textile firms’ unrelated diversification and their firm value during the period 2001-2005. Furthermore, the results indicate that group affiliation has complicated impacts on the diversification-performance relationship of the listed firms. Although group-affiliated firms are more successful in pursuing unrelated diversification when compared with stand-alone firms, such a difference in performance outcomes is statistically weak (as measured by Tobin’s Q. Furthermore, it is found that group-affiliated firms perform related diversification worse than their stand-alone counterparts (as measured by both ROA and Tobin’s Q. Conclusion: At late stages of the institutional transition, as in China at present, the dominant influence of institutional environments on the diversification-performance link of firms still works and motivates business groups to evolve organizationally. Such an organizational evolution has complex implications for group-affiliated firms’ diversification: the weak performance advantage from unrelated diversification suggests that business groups’ organizational evolution may contribute to the persistence of the comparative strength of business groups’ internal markets

    Full Text Available Due to the increasing pressure for companies to become more accountable and transparent regarding their actions, the stakeholders have been provided with information beyond the scope of company's financial performance including evidence of good corporate governance, source of raw material, the manufacturing process, and life cycle of the products. Business leaders have recognized the need to respond to these pressures by conducting operations focusing on the business success and meeting stakeholders' demands. Accordingly, in this study, a model for assessment of corporate sustainability was constructed considering the company's need to seek business longevity. Therefore, a case study was carried out in a medium sized textile industry in Paraná state adopting the Multicriteria Methodology for Decision Aid - Constructivist as the intervention tool. This methodology was chosen because it makes it possible to identify a set of performance indicators that characterize the company sustainability and to measure the organization properties and its commitment to sustainability, both individually and globally. The model identified that the company's strategy should include all the criteria of the economic, social, and environmental areas demonstrating that the differences between the replacement rates are strictly small. Furthermore, the model revealed that the actions of communication with the stakeholders are of great importance and that a lot of effort is needed in terms of awareness of employees, suppliers, customers, consumers, and the community of sustainability issues.Devido à crescente pressão para que as empresas sejam mais responsáveis e transparentes em suas ações, os stakeholders estão sendo atendidos em suas demandas por informações que vão além do desempenho financeiro da empresa, como evidências de uma boa governança corporativa, origem da matéria-prima, modo de fabricação e ciclo de vida dos produtos.

    2014-11-01

    Full Text Available The paper investigates the living and working conditions of textile workers in the city of Štip (Macedonia. The textile industry was highly developed during socialist times, but underwent a process of decline after the Yugoslav break-up. While it still represents a relevant economic sector for post-socialist Macedonia, the textile industry is highly dependent on outsourced orders from Western Europe. Local workers’ living and labour conditions, therefore, are affected by the global ‘race to the bottom’ for production costs that is typical of the garment industry. On the basis of a series of interviews conducted in Skopje and Štip with workers and factory owners, the article argues that contemporary working conditions in the Macedonian textile industry are characterised by poor labour rights, gender discrimination and widespread precarity. In contrast to the current circumstances, working and living conditions during socialist times are positively remembered by workers, who claim that their social status and living standards have deteriorated in the course of the last twenty years. This narrative of precarity is also partially shared by local entrepreneurs, who emphasise the global and local obstacles that hinder the development of the textile industry in Macedonia.

    Full Text Available It is well established that the water wettability of ma-terials is governed by both the chemical composition and the geometrical microstructure of the surface.1 Traditional textile wet processing treatments do in-deed rely fundamentally upon complete wetting out of a textile structure to achieve satisfactory perform-ance.2 However, the complexities introduced through the heterogeneous nature of the fiber surfaces, the nature of the fiber composition and the actual con-struction of the textile material create difficulties in attempting to predict the exact wettability of a par-ticular textile material. For many applications the ability of a finished fabric to exhibit water repellency (in other words low wettability is essential2 and po-tential applications of highly water repellent textile materials include rainwear, upholstery, protective clothing, sportswear, and automobile interior fabrics. Recent research indicates that such applications may benefit from a new generation of water repellent ma-terials that make use of the “lotus effect” to provide ultrahydrophobic textile materials.3,4 Ultrahydropho-bic surfaces are typically termed as the surfaces that show a water contact angle greater than 150°C with very low contact angle hysteresis.4 In the case of tex-tile materials, the level of hydrophobicity is often determined by measuring the static water contact angle only, since it is difficult to measure the contact angle hysteresis on a textile fabric because of the high levels of roughness inherent in textile structures.

    The official analytical method for tris(2,3-dibromopropyl)phosphate (TDBPP), which is banned from use in textile products by the "Act on Control of Household Products Containing Harmful Substances", requires revision. This study examined an analytical method for TDBPP by GC/MS using a capillary column. Thermal decomposition of TDBPP was observed by GC/MS measurement using capillary column, unlike in the case of gas chromatography/flame photometric detector (GC/FPD) measurement based on a direct injection method using a capillary megabore column. A quadratic curve, Y=2572X(1.416), was obtained for the calibration curve of GC/FPD in the concentration range 2.0-100 μg/mL. The detection limit was 1.0 μg/mL under S/N=3. The reproducibility for repetitive injections was satisfactory. A pretreatment method was established using methanol extraction, followed by liquid-liquid partition and purification with a florisil cartridge column. The recovery rate of this method was ~100%. TDBPP was not detected in any of the five commercial products that this study analyzed. To understand the cause of TDBPP decomposition during GC/MS (electron ionization; EI) measurement using capillary column, GC/MS (chemical ionization; CI), GC/FPD, and gas chromatography/flame ionization detector (GC/FID) measurements were conducted. It was suggested that TDBPP might thermally decompose both during GC injection, especially through a splitless injection method, and in the column or ion sources. To attempt GC/MS measurement, an injection part comprising quartz liner was used and the column length was halved (15 m); thus, only one peak could be obtained.

    Textiles may provide valuable bloodstain evidence to help piece together events or activities at violent crime scenes. However, in spite of over 75 years of research, there are still difficulties encountered in many cases in the interpretation and identification of bloodstains on textiles. In this study, we dripped porcine blood onto three types of fabric (plain woven, single jersey knit, and denim) that are supported in four different ways (hard, taut, loose, and semi-hard, i.e., fabric laid on denim). These four mounting methods represent different ways in which a textile may be present when blood from a violent act lands on it. This study investigates how the fabric mounting method and backing material affect the appearance of drip stains on textiles. We found that bloodstain patterns formed on fabric lying flat on a hard surface were very different from when the same fabric was suspended loosely. We also found that bloodstains formed on the technical back of single jersey knit were vastly different from those on the technical face. Interestingly, some drip stains showed blood passing through the textile and leaving a stain behind it that resembled insect stains. By observing, recording, and describing how a blood stained textile is found or presented at the scene, the analyst may be able to better understand bloodstains and bloodstain patterns on textiles, which could be useful to confirm or refute a witness's account of how blood came to be where it was found after a bloodshed event.

    Full Text Available Problem statement: The way of life of Thai people has involved utensils or things which made of bamboo since the ancient time. Rural Thai people use bamboo for building houses, making handicrafts, basketwork and household utensils. At present, thick bamboo is used and developed to many new products especially the textile products. Three purposes of this research were these: (1 to investigate the background of Thai textile production, (2 to investigate current situations and difficulties of Thai textile production and (3 to investigate the use of thick bamboo fiber for producing and developing Thai textiles. Approach: Research processes divided into 2 phases were these: the first phase was a quantitative experimental research type of bamboo fibers, the second phase was an application of the results of the first phase research to the phase was a qualitative research. The instruments for collecting data for the second phase research were a survey, an interview, a focus group interview and a workshop. Research areas were Ban Lung Pra Du, Amphoe Huay Talang, Nakhon Ratchasima Province, Amphoe Chonnaabot, Khon Kaen Province and Ban Tha Khon Yang, Amphoe Kantharawichai, Maha Sarakham Province. A sample of 200 people consisted of 20 key informants, 100 casual informants and 100 general informants. Quantitative data were analyzed by descriptive statistics such as percentage, mean and standard deviation. Qualitative data were analyzed by means of an interpretation within the concepts and theories involved. Research results were presented by means of a descriptive analysis. Results: (1 in terms of the background of Thai textile production, it revealed that there were human beings lived in Thailand about 7,000-8,000 years ago and they could use natural fiber from plants and animals for weaving. The evidence which confirmed this truth was the excavation of historical objects in prehistorically sites in Thailand and there were remnants clung to or filled in

    We developed a job exposure matrix (JEM) for the Shanghai textile industry constructed along three axes: industry sector, textile process, and hazardous agent. We assessed 35 different categories of dust, chemical, and physical agents for 149 textile processes within nine industry sectors: cotton, cotton/synthetic, cotton/other (nonsynthetic), wool, silk, synthetic, mineral, other mixed (e.g., wool and synthetic), and nonproduction. The JEM was constructed from two components: a priori assessment of the textile process by a team of U.S. industrial hygienists, and the prevalence of exposures reported by Chinese industrial hygienists in specific textile processes within the factory. The JEM was applied to an ongoing case-cohort study of cancer in women textile workers. The JEM assessed only dichotomous exposure (ever/never), and could be coupled with cumulative exposure by years of employment. The most common exposures in cotton mills were cotton dust and solvent exposures. Dyeing processes had the highest frequency of exposures, including solvents, acids, bases and caustics, bleaching agents, dyes, dye chemicals and intermediates, and formaldehyde. Only two processes were identified with formaldehyde exposure, beck dyeing and resin finishing. The most prevalent exposures among the subcohort, occurring in more than 60% of the women, were electromagnetic fields, lubricants, and cotton dust. More than one-third of subcohort subjects were also exposed to synthetic fiber dust, and slightly less than one-third of women were exposed to endotoxin. This JEM could be applicable for epidemiologic research in other textile industries.

    Making use of the DEA-based method of quadruplicate decomposition of labor productivity, the paper analyzes the influence of labor productivity of provincial textile industry in China, caused by the effect of technical efficiency, pure technical progress, changes of scale efficiency of capital per labor and of capital intensity from the year of 2002 to 2005. Its results show that the improvement of provincial textile industry labor productivity has mainly resulted from technical progress since 2003. Meanwhile, labor productivity of underdeveloped provinces has been growing faster than that of developed ones owing to technology diffusion. And then, the above-mentioned improvement has originated from the enhancement of capital deepening and technology efficiency. In addition, scale return of capital per labor appeared to decrease during the period from 2004 to 2005.

    introduce AgNM into the textile fiber since this will strongly minimize the release of AgNM during washing. If this is not possible due to technical limitations or other reasons, the introduction of a threshold level controlling the release of AgNM from textiles is suggested. It has to be noted that this study is a case study which is only valid for the investigated NM-300K and its potential application in textiles. - Highlights: • Washing: release rates of AgNM depend on furnishing in textiles. • Calculated PNECs for the aquatic compartment were low. • For the chosen scenarios no environmental risk of AgNM from textiles was observed. • AgNM is retained in sewage sludge. • In WWTP most of the silver adsorbs to sewage sludge and thus, may reach farmland.

    Noise was evaluated in six spinning and five weaving halls located in three textile mills in Egypt. Spindle speed (rpm) and loom speed (picks per minutes) were found to be important parameters affecting the noise level in these mills. Reduction of the number of spinning machines to five spindles per square meter of floor area will probably bring the noise level below the TLV. In the weaving departments, the decrease in the number of looms will not effectively reduce the noise level.

    Full Text Available Unconventional textiles are manufactured different from those obtained by the classic spinning weaving and knitting. They are obtained by mechanical or chemical consolidation of a textile backing up of fibrous layers or combinations of layers of fiber and yarn, fabrics and yarns, fabrics or knitted fabrics and fibers. For the apparel industry has expanded the use of unconventional fabrics especially in auxiliary materials they replace traditional materials such as woven tassel and buckram. Application of reinforcement layers have very important role in increasing the stability of form and material exploitation basic characteristics. Using unconventional fabrics used as insertions for clothing presents a desosibit advantage in terms of possible replacement joints bonded by heat sealed seam, thus saving time and using technology more accessible. For unconventional fabrics used as auxiliaries in the apparel industry is usually determined flexural stiffness, tensile strength, resistance to repeated stretches but more efficient in terms of proximity to the real conditions of the clothing is dynamic tensile resistance. Unconventional textile materials have a certain anisotropy in terms of the performed measurements. So, we followed the conducted research to highlight the anisotropy of several samples and characterization of best of unconventional materials in this regard, to be used under conditions effective as clothing industry.

    The waste generated by textile industries has been the target of numerous challenges due to their release to the environment without proper treatment. These problems have led many researchers to seek solutions that enable the use of waste as building materials. This study aimed to heat-treat the textile sludge, and evaluate their chemical, mineralogical and structural properties. The textile sludge was calcined in a muffle furnace, a heating rate of 10°C/min and 2 hours stabilization by the following temperatures 400°C, 450°C, 500°C, 550°C and 600°C. It was observed a reduction between 88 and 90% weight, indicating the presence of a large amount of formation water and organic matter. The sludge after calcinations was characterized by techniques such as X-ray diffraction, infrared and chemical analysis. The x-ray spectra showed predominant peaks of silica, which were confirmed by chemical analysis (86% silica). (author)

    Many organic/inorganic nanocomposites have been fabricated into fibrous materials using electrospinning techniques, because electrospinning processes have many attractive advantages and the ability to produce relatively large-scale continuous films. In this study, the polyvinyl alcohol (PVA)/silk/titanium dioxide (TiO2) nanocomposite self-cleaning textiles were successfully produced using electrospinning technique. After optimizing electrospinning conditions, we successfully obtained the PVA/silk/TiO2 nanocomposite fibers with average diameter of ˜220 nm and TiO2 concentration can be as high as 18.0 wt.%. For the case of the PVA/silk/TiO2 nanocomposite textile, the color of brilliant green coated on the textile surface changed from the initial green color to colorless after ultraviolet (UV) irradiation. Because of its worthy photocatalytic performance, the developed PVA/silk/TiO2 nanocomposite materials in this study will be beneficial for the design and fabrication of multifunctional fibers and textiles.

    In this work, we propose pharmaceutical textiles imprinted with lipid microparticles of Econazole nitrate (ECN) as a mean to improve patient compliance while maintaining drug activity. Lipid microparticles were prepared and characterized by laser diffraction (3.5±0.1 μm). Using an optimized screen-printing method, microparticles were deposited on textiles, as observed by scanning electron microscopy. The drug content of textiles (97±3 μg/cm(2)) was reproducible and stable up to 4 months storage at 25 °C/65% Relative Humidity. Imprinted textiles exhibited a thermosensitive behavior, as witnessed by a fusion temperature of 34.8 °C, which enabled a larger drug release at 32 °C (temperature of the skin) than at room temperature. In vitro antifungal activity of ECN textiles was compared to commercial 1% (wt/wt) ECN cream Pevaryl®. ECN textiles maintained their antifungal activity against a broad range of Candida species as well as major dermatophyte species. In vivo, ECN textiles also preserved the antifungal efficacy of ECN on cutaneous candidiasis infection in mice. Ex vivo percutaneous absorption studies demonstrated that ECN released from pharmaceutical textiles concentrated more in the upper skin layers, where the fungal infections develop, as compared to dermal absorption of Pevaryl®. Overall, these results showed that this technology is promising to develop pharmaceutical garments textiles for the treatment of superficial fungal infections.

    Silver (Ag) is increasingly used in consumer products like functionalized textiles and medical devices owing to its strong antimicrobial activity which is largely assigned to Ag ions released after oxidation of metallic Ag. To increase generation of Ag ions, in various products Ag is often present as nanoparticles. Ideally, Ag ions would remain on the surface of the skin to combat the bacteria and the uptake of Ag into the body should be limited. However, the Ag ions might penetrate across the skin into the body leading to adverse health effects. Data on in vivo uptake of Ag due to dermal exposure are scarce partly caused by the lack of suitable analytical approaches for the determination of Ag in biological matrices, but strongly needed to enable risk assessment of skin exposure to (nano) Ag containing products. With the developed approach, the presence of Ag in a functionalized textile is confirmed by using scanning electron microscopy (SEM). After in vivo dermal exposure to Ag containing textile material under ׳׳in use׳׳ exposure scenarios, the outermost layers of the skin (Stratum Corneum, SC) were sampled by using adhesive tapes with a size of 3.8cm(2). Different leaching and dissolution procedures of Ag from biological samples prior analysis by inductively coupled plasma mass spectrometry (ICPMS) have been evaluated. The developed method results in a limit of detection (LOD) of 2ng Ag per removed SC layer. The method allows the measurement of the Ag concentrations at different depths of the SC enabling the deduction of the percutaneous penetration kinetics. Due to the possible bio distribution within the whole body, an indirect exposure matrix (urine) was studied too. The detection power of the method permits measuring the ultra-trace concentrations of Ag in urine before and after dermal exposure; LOD is 0.010µg Ag/L urine.

    Toxicity of textile wastewaters (untreated and treated) and their ingredient chemicals was quantified in terms of their chemical characteristics, fish (Gambusia affinis) mortality and end point growth responses of duckweed (Lemna aequinoctialis) in short-term bioassays. Other parameters of fish bioassay were erythrocyte morphology and its counts. Despite of a definite correlation between data of biological tests (LC/EC(50) values) with that of chemical tests, biological tests were found to be relatively more sensitive to both wastewaters and ingredient chemicals. Amongst all the examined parameters of test organisms, fish RBCs (morphology and counts) sensitivity to pollutants in the wastewaters was usually maximum and therefore, their study should be included in the routine fish bioassay. Other advantage of biological test such as on Lemna is even detection of eutrophic potential of wastewaters, as noted at their higher dilutions. The ingredient chemicals (major) contributing maximum toxicity to textile dye wastewater were, acids (HCl and H(2)SO(4)), alkali (Na(2)O SiO(2)), salt (NaNO(2)) and heavy metal (Cu), whereas dyes (4) were relatively less toxic.

    Ethanol production from cotton linter and waste of blue jeans textiles was investigated. In the best case, alkali pretreatment followed by enzymatic hydrolysis resulted in almost complete conversion of the cotton and jeans to glucose, which was then fermented by Saccharomyces cerevisiae to ethanol. If no pretreatment applied, hydrolyses of the textiles by cellulase and beta-glucosidase for 24 h followed by simultaneous saccharification and fermentation (SSF) in 4 days, resulted in 0.140-0.145 g ethanol/g textiles, which was 25-26% of the corresponding theoretical yield. A pretreatment with concentrated phosphoric acid prior to the hydrolysis improved ethanol production from the textiles up to 66% of the theoretical yield. However, the best results obtained from alkali pretreatment of the materials by NaOH. The alkaline pretreatment of cotton fibers were carried out with 0-20% NaOH at 0 degrees C, 23 degrees C and 100 degrees C, followed by enzymatic hydrolysis up to 4 days. In general, higher concentration of NaOH resulted in a better yield of the hydrolysis, whereas temperature had a reverse effect and better results were obtained at lower temperature. The best conditions for the alkali pretreatment of the cotton were obtained in this study at 12% NaOH and 0 degrees C and 3 h. In this condition, the materials with 3% solid content were enzymatically hydrolyzed at 85.1% of the theoretical yield in 24 h and 99.1% in 4 days. The alkali pretreatment of the waste textiles at these conditions and subsequent SSF resulted in 0.48 g ethanol/g pretreated textiles used.

    Raw and biologically treated textile effluents were submerged filtrated using lab-fabricated hollow fiber nanofiltration membrane with a molecular weight cut-off of about 650 g/mol. Permeate flux, chemical oxygen demand (COD) reduction, color removal, membrane fouling, and cleaning were investigated and compared by varying the trans-membrane pressure (TMP) and volume concentrating factor (VCF). It was found that both raw and biologically treated textile effluents could be efficiently treated through submerged nanofiltration. The increase of TMP resulted in a decline in water permeability, COD reduction, color removal, and flux recovery ratio, while the increase of VCF resulted in both increased COD reduction and color removal. Under the TMP of 0.4 bar and VCF of 5.0, fluxes of 1.96 and 2.59 l/m(2)h, COD reductions of 95.7 and 94.2%, color removals of 99.0, and 97.3% and flux recovery ratios of 91.1 and 92.9% could be obtained in filtration of raw and biologically treated effluents, respectively. After filtration, the COD and color contents of the raw effluent declined sharply from 1780 to 325 mg/l and 1.200 to 0.060 Abs/cm, respectively, while for the biologically treated effluent, they decreased from 780 to 180 mg/l and 0.370 to 0.045 Abs/cm, respectively.

    2016-08-01

    While the properties of conductive fibres and coatings on textiles can easily be measured and calculated, magnetic coatings of fibres, yarns and fabrics still lack descriptions of their physical properties. Since magnetic textiles can be used for a variety of applications, from magnetic filters to invisible water-marks to magnetic coils and sensors, simulations would be supportive to understand and utilize their properties. The article gives an overview of different coatings on textile fibres, varying the magnetic materials as well as the fibre composition, giving rise to the interactions between neighbouring coated fibres. In this way, it is possible to understand the strong shape anisotropy which must be taken into account when the magnetic properties of textiles are to be tailored. Additionally, the differences between several possible magnetic coating materials become visible. This study can help adjusting the magnetic properties of textile fabrics to a desired application.

    Musculoskeletal disorders are common in those employed in the textile industry. The aim of the study is to assess musculoskeletal disorders among adolescent girls who are current employees of textile industries in comparison with the adolescent girls and young women who are past employees of textile industries and adolescent girls who have never been employed in the textile industry. Methodology This is a cross-sectional study. A total of 321 subjects, 107 in each study group were sampled. Standardized nordic questionnaires (SNQ) was used to assess musculoskeletal symptoms. Results More than half of the current employees (67.28%) and past employees (67.28%) reported musculoskeletal pain. Among the never been employed, 18.69% reported musculoskeletal pain. Neck and shoulder were the most common sites of musculoskeletal pain among the current employees (49.5% and 50.5%, respectively) and the past employees (45.8% and 49.5%, respectively). In the regression model, having ever been diagnosed for anemia (AOR 6.57, 95% CI 1.4 to 30.76), working for more than 48 h in a week (AOR 3.37, 95% CI 1.53 to 7.41) and the presence of depression (AOR 6.6, 95% CI 1.48 to 29.36) were significantly associated with the presence of musculoskeletal pain in the study participants. Conclusion Musculoskeletal disorders are a major occupational health problem among the adolescent and young women employees of textile industries. Working hours should be fixed at 48 h per week and anemia and depression should be treated to avert the work related musculoskeletal disorders in the study population.

    The sonophotocatalytic degradation of basic blue 9 industrial textile dye has been studied in the presence of ultrasound (20 kHz) over a TiO(2) slurry employing an UV lamp (15 W, 352 nm). It was observed that the color removal efficiency was influenced by the pH of the solution, initial dye concentration and TiO(2) amount. It was found that the dye degradation followed apparent first order kinetics. The rate constant increased by decreasing dye concentration and was affected by the pH of the solution with the highest degradation obtained at pH 7. The first order rate constants obtained with sonophotocatalysis were twofold and tenfold than those obtained under photocatalysis and sonolysis, respectively. The chemical oxygen demand was abated over 80%.

    Textiles able to perform electronic functions are known as e-textiles, and are poised to revolutionise the manner in which rehabilitation and assistive technology is provided. With numerous reports in mainstream media of the possibilities and promise of e-textiles it is timely to review research work in this area related to neurological rehabilitation.This paper provides a review based on a systematic search conducted using EBSCO- Health, Scopus, AMED, PEDro and ProQuest databases, complemented by articles sourced from reference lists. Articles were included if the e-textile technology described had the potential for use in neurological rehabilitation and had been trialled on human participants. A total of 108 records were identified and screened, with 20 meeting the broad review inclusion criteria. Nineteen user trials of healthy people and one pilot study with stroke participants have been reported.The review identifies two areas of research focus; motion sensing, and the measurement of, or stimulation of, muscle activity. In terms of motion sensing, E-textiles appear able to reliably measure gross movement and whether an individual has achieved a predetermined movement pattern. However, the technology still remains somewhat cumbersome and lacking in resolution at present. The measurement of muscle activity and the provision of functional electrical stimulation via e-textiles is in the initial stages of development but shows potential for e-textile expansion into assistive technologies.The review identified a lack of high quality clinical evidence and, in some cases, a lack of practicality for clinical application. These issues may be overcome by engagement of clinicians in e-textile research and using their expertise to develop products that augment and enhance neurological rehabilitation practice.

    Textile sensors, when embedded into clothing, can provide new ways of monitoring physiological signals, and improve the usability and comfort of such monitoring systems in the areas of medical, occupational health and sports. However, good electrical and mechanical contact between the electrode and the skin is very important, as it often determines the quality of the signal. This paper introduces a study where the properties of dry textile electrodes, textile electrodes moistened with water, and textile electrodes covered with hydrogel were studied with five different electrode sizes. The aim was to study how the electrode size and preparation of the electrode (dry electrode/wet electrode/electrode covered with hydrogel membrane) affect the measurement noise, and the skin-electrode impedance. The measurement noise and skin-electrode impedance were determined from surface biopotential measurements. These preliminary results indicate that noise level increases as the electrode size decreases. The noise level is high in dry textile electrodes, as expected. Yet, the noise level of wet textile electrodes is quite low and similar to that of textile electrodes covered with hydrogel. Hydrogel does not seem to improve noise properties, however it may have effects on movement artifacts. Thus, it is feasible to use textile embedded sensors in physiological monitoring applications when moistening or hydrogel is applied.

  18. Nanomaterial Case Study: A Comparison of Multiwalled ...

    Science.gov (United States)

    The draft document is intended to be used as part of a process to identify what is known and, more importantly, what is not yet known that could be of value in assessing the broad implications of specific nanomaterials. Like previous case studies (see History/ Chronology below), this draft case study on multiwalled carbon nanotubes (MWCNTs) is based on the comprehensive environmental assessment (CEA) approach, which consists of both a framework and a process. Unlike previous case studies this case study incorporates information about a traditional (i.e., “non-nano-enabled”) product, against which the MWCNT flame-retardant coating applied to upholstery textiles (i.e., the “nano-enabled” product) can be compared. The comparative element serves dual-purposes: 1) to provide a more robust database that facilitates identification of data gaps related to the nano-enabled product and 2) to provide a context for identifying key factors and data gaps for future efforts to evaluate risk-related trade-offs between a nano-enabled and non-nano-enabled product. This draft case study does not represent a completed or even a preliminary assessment of MWCNTs; rather, it uses the CEA framework to structure information from available literature and other resources (e.g., government reports) on the product life cycle, fate and transport processes in various environmental media, exposure-dose characterization, and impacts in human, ecological, and environmental receptors.

    2012-11-01

    Smart textiles research represents a new model for generating creative and novel solutions for integrating electronics into unusual environments and will result in new discoveries that push the boundaries of science forward. A key driver for smart textiles research is the fact that both textile and electronics fabrication processes are capable of functionalizing large-area surfaces at very high speeds. In this article we review the history of smart textiles development, introducing the main trends and technological challenges faced in this field. Then, we identify key challenges that are the focus of ongoing research. We then proceed to discuss fundamentals of smart textiles: textile fabrication methods and textile interconnect lines, textile sensor, and output device components and integration of commercial components into textile architectures. Next we discuss representative smart textile systems and finally provide our outlook over the field and a prediction for the future.

  12. PREPARATION OF BAMBOO DISSOLVING PULP FOR TEXTILE PRODUCTION; PART 1. STUDY ON PREHYDROLYSIS OF GREEN BAMBOO FOR PRODUCING DISSOLVING PULP

    Directory of Open Access Journals (Sweden)

    Xiaojuan Ma

    2011-03-01

    Full Text Available Prehydrolysis was used as the first treatment of bamboo materials for producing high dissolving pulp for textile applications. In this paper, green bamboo (Dendrocalamopsis oldhami was hydrolyzed in water, and the hydrolysis process was optimized. The morphology and super-molecular structures of the raw material and prehydrolyzed material were studied by SEM and XRD, respectively. Based on the optimum conditions, a study of the kinetics and mechanism showed that pentosan dissolution during the hydrolysis process was a first order reaction. When cooking temperature was 150 oC, 160 oC, 170 oC, and 180 oC, the corresponding reaction rate constants were 0.00411h-1, 0.00495h-1, 0.00730h-1, and 0.00925h-1, respectively. The activation energy was 44.94 kJ/mol based on the Arrhenius empirical equation. SEM results revealed that after the pre-hydrolysis process, the bamboo structure became loose because of hemicellulose dissolution, which created a favorable environment for chemical penetration in the subsequent treatment. Furthermore, the degree of crystallinity was increased from 45.43% to 57.06% during the prehydrolysis. Both the treated and the untreated fibers were assumed to be cellulose I.

    Full Text Available This study includes the research work which was carried out to investigate the range of difficulties faced by the workers and its effects on them while working in textile based cottage industries along with their causes. This research provides necessary tip-offs to solve those problems in a systematic way. Therefore, it was considered to know the number of machines (looms operated by one worker, number of machines in one unit and number of operators in one unit. The minimum and maximum noise levels were recorded by using digital sound level meter to compute average noise level/ unit. To identify the health problems like respiratory, hearing/listening, irritation, heart/BP, annoyance and headache faced by the workers, the survey was conducted. In present research work the minimum noise recorded was 101.6dB (A and maximum as 109.8dB (A, which was compared with OSHA and WHO (World Health Organization standards. Result of this study shows that due to high intensity of noise generated by looms and dusts at work places, workers were facing the mental and physical problems.

    2015-12-01

    In this work, the fabrication of Rochelle salt based piezoelectric textiles are shown. Structures composed of fibers and Rochelle salt are easily produced using green processes. Both manufacturing and the material itself are really efficient in terms of environmental impact, considering the fabrication processes and the material resources involved. Additionally Rochelle salt is biocompatible. In this green paradigm, active sensing or actuating textiles are developed. Thus processing method and piezoelectric properties have been studied: (1) pure crystals are used as acoustic actuator, (2) fabrication of the textile-based composite is detailed, (3) converse effective d33 is evaluated and compared to lead zirconate titanate ceramic. The utility of textile-based piezoelectric merits its use in a wide array of applications.

    This article describes case study research for nursing and healthcare practice. Case study research offers the researcher an approach by which a phenomenon can be investigated from multiple perspectives within a bounded context, allowing the researcher to provide a 'thick' description of the phenomenon. Although case study research is a flexible approach for the investigation of complex nursing and healthcare issues, it has methodological challenges, often associated with the multiple methods used in individual studies. These are explored through examples of case study research carried out in practice and education settings. An overview of what constitutes 'good' case study research is proposed.

  16. Use of calcined layered double hydroxides for the removal of color and organic matter from textile effluents: kinetic, equilibrium and recycling studies

    Directory of Open Access Journals (Sweden)

    T. P. F. Teixeira

    2014-03-01

    Full Text Available This paper presents data for the synthesis and characterization of layer double hydroxides (LDH and their use for color and chemical oxygen demand (COD removal from effluents generated by a textile industry. Adsorption studies with raw and biologically treated (activated sludge textile effluent showed that the pseudo-second order model best fitted the experimental data, leading to adsorption coefficients of 39.1 and 102.9 mgCOD/gLDH for raw and treated effluents, respectively. The best conditions for color and COD removal were obtained at lower values of temperature and pH (25 °C and pH 7 and, in these conditions, an LDH dose of 10 g/L resulted in color removal efficiencies of 56% for samples of raw and 66% for samples of treated effluent. Recycling studies indicated that the reuse of thermally treated LDH led to a progressive loss in the removal efficiencies of COD and color. The reduction was more pronounced with samples of the raw textile effluent. LDH characterization performed before and after each adsorption and regeneration experiment showed that there was no intercalation of dye molecules in the interlayer region of the LDH, indicating that COD and color removal might be due to the adsorption of organic molecules onto the LDH surface.

    2015-01-01

    Complete decolorization and detoxification of Reactive Orange 4 within 5 h (pH 6.6, at 30°C) by isolated Lysinibacillus sp. RGS was observed. Significant reduction in TOC (93%) and COD (90%) was indicative of conversion of complex dye into simple products, which were identified as naphthalene moieties by various analytical techniques (HPLC, FTIR, and GC-MS). Supplementation of agricultural waste extract considered as better option to make the process cost effective. Oxido-reductive enzymes were found to be involved in the degradation mechanism. Finally Loofa immobilized Lysinibacillus sp. cells in a fixed-bed bioreactor showed significant decolorization with reduction in TOC (51 and 64%) and COD (54 and 66%) for synthetic and textile effluent at 30 and 35 mL h(-1) feeding rate, respectively. The degraded metabolites showed non-toxic nature revealed by phytotoxicity and photosynthetic pigments content study for Sorghum vulgare and Phaseolus mungo. In addition nitrogen fixing and phosphate solubilizing microbes were less affected in treated wastewater and thus the treated effluent can be used for the irrigation purpose. This work could be useful for the development of efficient and ecofriendly technologies to reduce dye content in the wastewater to permissible levels at affordable cost.

    2016-03-01

    We present the results of experimental investigation of ultrasonic washing of textiles. The results demonstrate that cavitation bubbles oscillating in acoustic fields are capable of removing soils from textiles. Since the washing performance is mitigated in a large washing bath when using an ultrasonic transducer, we propose a novel washing scheme by combining the ultrasonic vibration with a conventional washing method utilizing kinetic energy of textiles. It is shown that the hybrid washing scheme achieves a markedly enhanced performance up to 15% in comparison with the conventional washing machine. This work can contribute to developing a novel laundry machine with reduced washing time and waste water.

  19. Mathematical modeling of a convective textile drying process

    G. Johann

    2014-12-01

    Full Text Available This study aims to develop a model that accurately represents the convective drying process of textile materials. The mathematical modeling was developed from energy and mass balances and, for the solution of the mathematical model, the technique of finite differences, in Cartesian coordinates, was used. It transforms the system of partial differential equations into a system of ordinary equations, with the unknowns, the temperature and humidity of both the air and the textile material. The simulation results were compared with experimental data obtained from the literature. In the statistical analysis the Shapiro-Wilk test was used to validate the model and, in all cases simulated, the results were p-values greater than 5 %, indicating normality of the data. The R-squared values were above 0.997 and the ratios Fcalculated/Fsimulated, at the 95 % confidence level, higher than five, indicating that the modeling was predictive in all simulations.

    Specos, M M Miró; García, J J; Tornesello, J; Marino, P; Vecchia, M Della; Tesoriero, M V Defain; Hermida, L G

    2010-10-01

    Microcapsules containing citronella essential oil were prepared by complex coacervation and applied to cotton textiles in order to study the repellent efficacy of the obtained fabrics. Citronella released from treated textiles was indirectly monitored by the extractable content of its main components. Repellent activity was assessed by exposure of a human hand and arm covered with the treated textiles to Aedes aegypti mosquitoes. Fabrics treated with microencapsulated citronella presented a higher and longer lasting protection from insects compared to fabrics sprayed with an ethanol solution of the essential oil, assuring a repellent effect higher than 90% for three weeks. Complex coacervation is a simple, low cost, scalable and reproducible method of obtaining encapsulated essential oils for textile application. Repellent textiles were achieved by padding cotton fabrics with microcapsules slurries using a conventional pad-dry method. This methodology requires no additional investment for textile finishing industries, which is a desirable factor in developing countries.

  1. Biocidal textiles can help fight nosocomial infections.

    Science.gov (United States)

    Borkow, Gadi; Gabbay, Jeffrey

    2008-01-01

    The rates of nosocomial infections, especially by those caused by antibiotic resistant bacteria, are increasing alarmingly over the globe. Although more rigorous infection control measures are being implemented, it is clear that the current modalities to reduce nosocomial infections are not sufficient. Textiles are an excellent substrate for bacterial growth under appropriate moisture and temperature conditions. Patients shed bacteria and contaminate their pyjamas and sheets. The temperature and humidity between the patients and the bed are appropriate conditions allowing for effective bacterial proliferation. Several studies have found that personnel in contact with contaminated textiles were the source of transmission of the micro-organisms to susceptible patients. Furthermore, it has been reported that bed making in hospitals releases large quantities of micro-organisms into the air, which contaminate the immediate and non-immediate surroundings. Contaminated textiles in hospitals can thus be an important source of microbes contributing to endogenous, indirect-contact, and aerosol transmission of nosocomial related pathogens. We hypothesize that the use of antimicrobial textiles, especially in those textiles that are in close contact with the patients, may significantly reduce bioburden in clinical settings and consequently reduce the risk of nosocomial infections. These textiles should possess broad spectrum biocidal properties. They should be safe for use and highly effective against antibiotic resistant micro-organisms, including those that are commonly involved in hospital-acquired infections, and they should not permit the development of resistant micro-organisms to the active compound.

    2012-04-01

    Plants of Glandularia pulchella (Sweet) Tronc. performed decolorization of structurally different dyes to varying extent because of induction of different set of enzymes in response to specific dyes. Differential pattern of enzyme induction with respect to time was obtained for lignin peroxidase, veratryl alcohol oxidase, tyrosinase and dichlorophenolindophenol reductase during the decolorization of dye mixture, whose combined action resulted in greater and faster decolorization of dyes. HPLC, FTIR and High Performance Thin Layer Chromatography (HPTLC) analysis confirmed degradation of dyes from textile effluent and mixture. HPTLC demonstrated progressive decolorization of dye mixture along with preferential degradation of the dyes. G. pulchella showed reduction in American Dye Manufacturer's Institute from 405 to 21 and 418 to 22, in case of textile effluent and mixture of dyes respectively. The non-toxic nature of the metabolites of degraded textile dye effluent and mixture of dyes was revealed by phytotoxicity studies.

    Electrowetting of two nonwoven textile platforms is reported. Demonstrated nonwoven textiles include a polyethylene naphthalate film that was laser milled with ˜125μm pores, and pressed paper that was made using wood microfibers of 35-50μm diameter. Vacuum deposition provided an Al electrode on the polymer textile whereas layer-by-layer nanoassembly provided an organic PEI-PEDOT:PSS electrode on the wood microfibers. Both textiles were electrically insulated with parylene C and fluoropolymer. Irreversible electrowetting of water was achieved over contact angles of ˜120° to ˜70° by applying 0-100V. Completely reversible electrowetting of water/oil was also demonstrated.

  10. SMART FABRICS: A CASE STUDY IN INDUSTRIAL REVIVAL

    Directory of Open Access Journals (Sweden)

    Radan Ungureanu Adriana

    2013-07-01

    Full Text Available The movements on the world market suffered by the traditional textile industry bring us nowadays to reconsider the rebirth of the textile industry on new coordinates by the concentration of the latest technologies in order to satisfy the more and more demanding requests of the consumer. This paper tries to emphasize the idea that revitalization on a territory where there had been a strong development of a traditional textile industry in the past is possible now by configuring a new industry by means of some leader companies in their field of activity which create and develop new value sources with the advantages of the variant which integrates the latest interdisciplinary technologies, the so-called “key enabling technologies” (KETs, such as the microsystems, the smart materials, nano- and bio-technologies, and photonics. The KETs have a key role in creating the so-called industry of smart fabrics as it is shown in this summary case study for this very new born industry. All these technologies enable the appearance of some products fundamentally new of high interest, which furnish substantial economic advantages and involve industries with which they had no connection in the past. The main vectors in this effort of industrial transformation are the companies which are the best placed on the market of new industrial technologies generally called KETs, which combines the new ideas of economical organization through an intensive use of capital with the sustained effort of research-development, the usage of highly qualified labour force, and their geographical positioning at the points which best respond to their operational requirements. The competitive disadvantages of some countries with respect to the cheap labour force and the supply of raw materials essential for textile industry can be compensated by the re-orientation to the configuration of a new model of smart textiles and finally will contribute to re-launch the economic

    Full Text Available ResumenEl sector al que correspondió el mayor protagonismo dentro de la industria europea moderna fue, sin lugar a dudas, el textil. Ello no representaba, en realidad, novedad alguna, pues la industria medieval se desarrolló precisamente en función primordialmente de la fabricación de tejidos. El vestido, al tiempo que una necesidad inmediata, resulta expresión visual de distinción social, aún más que la decoración de la vivienda. Por ello la industria textil creció a expensas tanto de la necesidad como del lujo. Uno de los grandes cambios que se producen en este tipo de industria durante todo el siglo XV y se consolida en el XVI se centra en las relaciones de producción, en la utilización de mano de obra campesina y la consolidación del ciclo de producción artesano rural. La mano de obra rural comienza a trabajar por su cuenta o en dependencia del empresario-productor de la ciudad. Si bien, la profunda transformación de la industria textil tendrá lugar en el siglo XVIII, con la revolución industrial.La transformación de la industria textil del siglo XVI propició la expansión de una nueva figura en el ámbito mercantil, que se denomina mercader-empresario, y por tanto, del sistema doméstico de producción conocido como Verlagssystem. Este nuevo sistema implicará modificaciones de factores claves para el desarrollo de las futuras sociedades mercantiles como pueden ser: el capital, la utilización de la materia prima y su proceso de transformación, la formación de los costes de producción y comercialización, la obtención de beneficios y su distribución, la concentración del capital y la generación de rentes. En definitiva, la creación de una nueva clase social, la burguesía. Este trabajo se centra en la industria sedera de la ciudad de Toledo en el siglo XVI.AbstractThe textile sector, was the greater protagonist, without doubt, within the modern European industry. It did not represent, in fact, newness some

    2015-05-01

    Full Text Available Nanoscience and nanotechnology are the study and application of extremely small things and can be used across all the other science fields, such as chemistry, biology, physics, materials science, and engineering. Nanotechnology overcomes the limitation of applying conventional methods to impart certain properties to textile materials. There is no doubt that in the next few years nanotechnology will penetrate into every area of the textile industry. Nanotextiles are nanoscale fibrous materials that can be fictionalized with a vast array of novel properties, including antibiotic activity, self-cleaning and the ability to increase reaction rates by providing large surface areas to potential reactants. These materials are used not only as cloth fabric, but as filter materials, wound-healing gauzes and antibacterial food packaging agents in food industry. World demand for nano-materials will rise more than two-and-a-half times to $5.5 billion in 2016 driven by a combination of increased market penetration of existing materials, and ongoing development of new materials and applications. In recent years was demonstrated that nanotechnology can be used to enhance textile attributes, such as fabric softness, durability and breathability, water repellency, fire retardancy, antimicrobial properties in fibers, yarns and fabrics. The development of smart nanotextiles has the potential to revolutionize the production of fibers, fabrics or nonwovens and functionality of our clothing and all types of textile products and applications. Nanotechnology is considered one of the most promising technologies for the 21st century. Today is said that if the IT is the wave of the present, the nanotechnology is the wave of the present, the nanotechnology is the wave of the future.

    2016-07-01

    Inventory has been a major concern in supply chain and numerous researches have been done lately on inventory control which brought forth a number of methods that efficiently manage inventory and related overheads by reducing cost of replenishment. This research is aimed towards providing a better replenishment policy in case of multi-product, single supplier situations for chemical raw materials of textile industries in Bangladesh. It is assumed that industries currently pursue individual replenishment system. The purpose is to find out the optimum ideal cycle time and individual replenishment cycle time of each product for replenishment that will cause lowest annual holding and ordering cost, and also find the optimum ordering quantity. In this paper indirect grouping strategy has been used. It is suggested that indirect grouping Strategy outperforms direct grouping strategy when major cost is high. An algorithm by Kaspi and Rosenblatt (1991) called RAND is exercised for its simplicity and ease of application. RAND provides an ideal cycle time (T) for replenishment and integer multiplier (ki) for individual items. Thus the replenishment cycle time for each product is found as T×ki. Firstly, based on data, a comparison between currently prevailing (individual) process and RAND is provided that uses the actual demands which presents 49% improvement in total cost of replenishment. Secondly, discrepancies in demand is corrected by using Holt's method. However, demands can only be forecasted one or two months into the future because of the demand pattern of the industry under consideration. Evidently, application of RAND with corrected demand display even greater improvement. The results of this study demonstrates that cost of replenishment can be significantly reduced by applying RAND algorithm and exponential smoothing models.

    Compression therapy is the cornerstone of treatment in the case of venous leg ulcers. The therapy outcome is strictly dependent on the pressure distribution produced by bandages along the lower limb length. To date, pressure monitoring has been carried out using sensors that present considerable drawbacks, such as single point instead of distributed sensing, no shape conformability, bulkiness and constraints on patient's movements. In this work, matrix textile sensing technologies were explored in terms of their ability to measure the sub-bandage pressure with a suitable temporal and spatial resolution. A multilayered textile matrix based on a piezoresistive sensing principle was developed, calibrated and tested with human subjects, with the aim of assessing real-time distributed pressure sensing at the skin/bandage interface. Experimental tests were carried out on three healthy volunteers, using two different bandage types, from among those most commonly used. Such tests allowed the trends of pressure distribution to be evaluated over time, both at rest and during daily life activities. Results revealed that the proposed device enables the dynamic assessment of compression mapping, with a suitable spatial and temporal resolution (20 mm and 10 Hz, respectively). In addition, the sensor is flexible and conformable, thus well accepted by the patient. Overall, this study demonstrates the adequacy of the proposed piezoresistive textile sensor for the real-time monitoring of bandage-based therapeutic treatments.

    Full Text Available Textile-based electronic components have gained interest in the fields of science and technology. Recent developments in nanotechnology have enabled the integration of electronic components into textiles while retaining desirable characteristics such as flexibility, strength, and conductivity. Various materials were investigated in detail to obtain current conductive textile technology, and the integration of electronic components into these textiles shows great promise for common everyday applications. The harvest and storage of energy in textile electronics is a challenge that requires further attention in order to enable complete adoption of this technology in practical implementations. This review focuses on the various conductive textiles, their methods of preparation, and textile-based electronic components. We also focus on fabrication and the function of textile-based energy harvesting and storage devices, discuss their fundamental limitations, and suggest new areas of study.

    2014-01-01

    Textile dyes are among the most problematic pollutants because of their toxicity on several organisms and ecosystems. Many of the chemicals used in the textile industry may represent some health concerns. The determination of the radioactivity in textile dyes is therefore very important for both human health and environment. The study was designated to determine, for the first time, the values of (238)U, (232)Th and (40)K in nine different dyes employed in the textile industry using gamma spectrometry with a Hyper Pure Germanium (HPGe) detector. The mean activity concentrations of (238)U, (232)Th and (40)K were 29.37 ± 4.48, 1.15 ± 0.13 and 565 ± 4 Bq/kg, respectively. The calculated radium equivalents for all samples were lower than the maximum admissible value (370 Bq/kg). The absorbed dose rates due to the natural radioactivity of the investigated samples ranged from 2.94 ± 0.05 to 166 ± 3 nGy/h. So, the absorbed dose rates for all samples of textile dyes were lower than the international recommended value (55 nGy/h) except the yellow dye (166 ± 3 nGy/h), which recorded a significant radiological hazard. The external hazard index was also calculated. Conclusively, the results have indicated that the textile dyes may possess a measurable amount of radioactivity that should be taken into account. Therefore, safety rules and precautions should be applied for dyes used in the textile industry and for people working in this field.

    1992-01-01

    The NASA LaRC is conducting and sponsoring research to explore the benefits of textile reinforced composites for civil transport aircraft primary structures. The objective of this program is to develop and demonstrate the potential of affordable textile reinforced composite materials to meet design properties and damage tolerance requirements of advanced aircraft structural concepts. In addition to in-house research, the program was recently expanded to include major participation by the aircraft industry and aerospace textile companies. The major program elements include development of textile preforms, processing science, mechanics of materials, experimental characterization of materials, and development and evaluation of textile reinforced composite structural elements and subcomponents. The NASA Langley in-house focus is as follows: development of a science-based understanding of resin transfer molding (RTM), development of powder-coated towpreg processes, analysis methodology, and development of a performance database on textile reinforced composites. The focus of the textile industry participation is on development of multidirectional, damage-tolerant preforms, and the aircraft industry participation is in the areas of design, fabrication and testing of textile reinforced composite structural elements and subcomponents. Textile processes such as 3D weaving, 2D and 3D braiding, and knitting/stitching are being compared with conventional laminated tape processes for improved damage tolerance. Through-the-thickness reinforcements offer significant damage tolerance improvements. However, these gains must be weighed against potential loss in in-plane properties such as strength and stiffness. Analytical trade studies are underway to establish design guidelines for the application of textile material forms to meet specific loading requirements. Fabrication and testing of large structural components are required to establish the full potential of textile reinforced

The strength of the case study design is that it allows for uncovering or suggesting causal relationships in real-life settings through an intensive and rich collection of data. According to Hilliard (1993), the opposite applies for extensive...... designs, in which a small amount of data is gathered on a large number of subjects. With the richness of data, the intensive design is ―the primary pragmatic reason for engaging in single-case or small N research‖ (p. 374) and for working from an idiographic rather than a nomothetic perspective....

    In this work, we studied the supercritical water oxidation (SCWO) of the textile sludge, the hydrothermal conversion of typical textile compounds and the corrosion properties of stainless steel 316. Moreover, the influence mechanisms of NaOH during these related processes were explored. The results show that decomposition efficiency for organic matter in liquid phase of the textile sludge was improved with the increment of reaction temperature or oxidation coefficient. However, the organic substance in solid phase can be oxidized completely in supercritical water. Serious coking occurred during the high pressure water at 250-450°C for the Reactive Orange 7, while at 300 and 350°C for the polyvinyl alcohol. The addition of NaOH not only accelerated the destruction of organic contaminants in the SCWO reactor, but effectively inhibited the dehydration conversion of textile compounds during the preheating process, which was favorable for the treatment system of textile sludge. The corrosion experiment results indicate that the stainless steel 316 could be competent for the body materials of the reactor and the heat exchangers. Furthermore, there was prominent enhancement of sodium hydroxide for the corrosion resistance of 316 in subcritical water. On the contrary the effect was almost none during SCWO.

    In recent years, textile materials with special applications in the cosmetic field have been developed. A new sector of cosmetic textiles is opened up and several cosmetic textile products are currently available in the market. Microencapsulation technology is an effective technique to control the release properties of active ingredients that prolong the functionality of cosmetic textiles. This study discusses the development of cosmetic textiles and addresses microencapsulation technology with respect to its historical background, significant advantages, microencapsulation methods and recent applications in the textile industry. Gelatin microcapsules containing vitamin C were prepared using emulsion hardening technique. Both the optical microscopy and scanning electron microscopy demonstrated that the newly developed microcapsules were in the form of core-shell spheres with relatively smooth surface. The particle size of microcapsules ranged from 5.0 to 44.1 microm with the average particle size being 24.6 microm. The gelatin microcapsules were proved to be non-cytotoxic based on the research findings of the toxicity studies conducted on human liver and breast cell lines as well as primary bone marrow culture obtained from patient with non-malignant haematological disorder. The gelatin microcapsules were successfully grafted into textile materials for the development of cosmetic textiles.

  12. THE TECHNIQUES FOR CREATING IMAGES OF PRINT PATTERNS IN THE PROCESS OF STUDYING THE DEVELOPMENT OF ARTISTIC TASTES OF STUDENTS-PAINTERS BY MEANS OF TEXTILE GRAPHICS

    Directory of Open Access Journals (Sweden)

    M. K. KULIKOVA

    2015-01-01

    Full Text Available The character of textile images is closely linked with the specifics of the production technology and this largely determines some of the techniques and types of graphic organization. The textile graphics is continuously enriched with new techniques. Some of them were borrowed from easel graphic art, decorative art, design. This article describes some techniques used to create the images of print patterns in the process of studying the development of artistic taste of art students by means of textile graphics. The scenic effect may be obtained by spatial (additive mixing of colors. This technique is reflected in the paintings of artists-pointillists. The picturesque effect of their works is explained by using different color strokes (mostly of pure hues, which created the effect of vibration of colors. However, the palette of painters was unlimited, and students-painters have usually a very limited number of colors. To create drawings of pointillistic nature, it is necessary to select carefully 3 - 4 saturated colors (but not additive ones to avoid achromatic effect. Patterns may be developed by dots, strokes, touches. The color change may be influenced not only by the neighboring tones, but also by the size, shape of spots and the distance between them. The main feature of drawings executed in pointillist technique is the general leading color shade, i.e. the prevalence of certain colors or combination of colors. The background color is not of less importance, because it actively effects the color combinations. As it can be seen, the techniques for creating image print patterns, textile compositions may be made by a variety of methods: graphical, pictorial, with a complex interconnection of their combinations. But with all originality of the artistic idea, clarity and conciseness of graphic techniques, careful reasoning of the selection of methods of expression will always enhance the development of artistic

  14. Electrical Conductivity in Textiles

    Science.gov (United States)

    2006-01-01

    Copper is the most widely used electrical conductor. Like most metals, though, it has several drawbacks: it is heavy, expensive, and can break. Fibers that conduct electricity could be the solutions to these problems, and they are of great interest to NASA. Conductive fibers provide lightweight alternatives to heavy copper wiring in a variety of settings, including aerospace, where weight is always a chief concern. This is an area where NASA is always seeking improved materials. The fibers are also more cost-effective than metals. Expenditure is another area where NASA is always looking to make improvements. In the case of electronics that are confined to small spaces and subject to severe stress, copper is prone to breaking and losing connection over time. Flexible conductive fibers eliminate that problem. They are more supple and stronger than brittle copper and, thus, find good use in these and similar situations. While clearly a much-needed material, electrically conductive fibers are not readily available. The cost of new technology development, with all the pitfalls of troubleshooting production and the years of testing, and without the guarantee of an immediate market, is often too much of a financial hazard for companies to risk. NASA, however, saw the need for electrical fibers in its many projects and sought out a high-tech textile company that was already experimenting in this field, Syscom Technology, Inc., of Columbus, Ohio. Syscom was founded in 1993 to provide computer software engineering services and basic materials research in the areas of high-performance polymer fibers and films. In 1999, Syscom decided to focus its business and technical efforts on development of high-strength, high-performance, and electrically conductive polymer fibers. The company developed AmberStrand, an electrically conductive, low-weight, strong-yet-flexible hybrid metal-polymer YARN.

    2017-06-15

    In this study the feasibility of treating dyeing wastewater with sulfate reducing granular sludge was explored, focusing on decolorization/degradation of azo dye (Procion Red HE-7B) and the performance of microbial consortia under alkaline conditions (pH=11). Efficiency of HE-7B degradation was influenced strongly by the chemical oxygen demand (COD) concentration which was examined in the range of 500-3000mg/L. COD removal efficiency was reduced at high COD concentration, while specific removal rate was enhanced to 17.5 mg-COD/gVSSh(-1). HE-7B removal was also improved at higher organic strength with more than 90% removal efficiency and a first-rate removal constant of 5.57h(-1) for dye degradation. Three dye-degradation metabolites were identified by HPLC-MS. The granular structure provided enhanced removal performance for HE-7B and COD in comparison to a near-identical floc SRB system and the key functional organisms were identified by high throughput sequencing. This study demonstrates an example of a niche application where SRB granules can be applied for high efficient and cost-effective treatment of a wastewater under adverse environmental conditions.

    Full Text Available The present study deals with the biomordant assisted application of natural extracts obtained from red raspberry (Rubus idaeus L. fruits onto two different cellulosic supports – flax and bamboo. The study relies on the improvement of multifunctionalities such as colour fastness, washing and rubbing fastness, due to the synergism provided by the co-assistance of both a biomordant, and the complex resulted by inclusion of the pigment molecule, in the cavity of MCT-β-CD; it is well known that natural dye molecule have a good selectivity binding to the hydrophobic monochloro-triazynil-cyclodextrin’s (MCT-β-CD cavity to form inclusion complexes. An investigation system provided the characterization of the composites: FT-IR spectroscopy stressed the main chemical bonds created between MCT-β-CD as host molecule and guest molecule represented by natural colorant molecule; Brunauer-Emmett-Teller (BET Surface Area Analysis completes the analysis, proving the positive contribution of MCT-β-cyclodextrin grafting. Dyeing fastness and colour modifications were conclusive for this research. Samples of bamboo knitting are less colorful than those of the flax fabric in terms of high absorption capacity and stability / durability of natural dye applied by inclusion within cyclodextrin’s inner. The results of analysis revealed improvement of washing and rubbing fastness (1-1.5 points. Colour modifications noticed due to the colorant deposition were quantified from up to 3 points.

    2013-01-01

    Full Text Available Adsorption of heavy metals (Cr, Cd, Pb, Ni, and Cu onto Activated Teff Straw (ATS has been studied using batch-adsorption techniques. This study was carried out to examine the adsorption capacity of the low-cost adsorbent ATS for the removal of heavy metals from textile effluents. The influence of contact time, pH, Temperature, and adsorbent dose on the adsorption process was also studied. Results revealed that adsorption rate initially increased rapidly, and the optimal removal efficiency was reached within about 1 hour. Further increase in contact time did not show significant change in equilibrium concentration; that is, the adsorption phase reached equilibrium. The adsorption isotherms could be fitted well by the Langmuir model. The value in the present investigation was less than one, indicating that the adsorption of the metal ion onto ATS is favorable. After treatment with ATS the levels of heavy metals were observed to decrease by 88% (Ni, 82.9% (Cd, 81.5% (Cu, 74.5% (Cr, and 68.9% (Pb. Results indicate that the freely abundant, locally available, low-cost adsorbent, Teff straw can be treated as economically viable for the removal of metal ions from textile effluents.

  18. Antimicrobial Approaches for Textiles: From Research to Market

    Directory of Open Access Journals (Sweden)

    Diana Santos Morais

    2016-06-01

    Full Text Available The large surface area and ability to retain moisture of textile structures enable microorganisms’ growth, which causes a range of undesirable effects, not only on the textile itself, but also on the user. Due to the public health awareness of the pathogenic effects on personal hygiene and associated health risks, over the last few years, intensive research has been promoted in order to minimize microbes’ growth on textiles. Therefore, to impart an antimicrobial ability to textiles, different approaches have been studied, being mainly divided into the inclusion of antimicrobial agents in the textile polymeric fibers or their grafting onto the polymer surface. Regarding the antimicrobial agents, different types have been used, such as quaternary ammonium compounds, triclosan, metal salts, polybiguanides or even natural polymers. Any antimicrobial treatment performed on a textile, besides being efficient against microorganisms, must be non-toxic to the consumer and to the environment. This review mainly intends to provide an overview of antimicrobial agents and treatments that can be performed to produce antimicrobial textiles, using chemical or physical approaches, which are under development or already commercially available in the form of isolated agents or textile fibers or fabrics.

  19. A Study of Strength Transfer from tow to Textile Composite Using Different Reinforcement Architectures

    2012-06-01

    The paper proposes an experimental and analytical approach of designing composites with the predetermined ultimate strength, reinforced with warp interlock fabrics. In order to better understand the phenomena of transfer of tensile properties from a tow to the composite, intermediate phases of composite manufacturing have also been taken into account and tensile properties of tows taken from the loom and the woven reinforcements have also been tested. Process of transfer of mechanical properties of raw materials to the final product (composite) depends on various structural factors. Here the influence of weave structure, which ultimately influences crimp has been studied. A strength transfer coefficient has been proposed which helps in estimating the influence of architectural parameters on 3D woven composites. 3 woven interlock reinforcements were woven to form composites. The coefficients of strength transfer were calculated for these three variants. The structural parameters were kept the same for these three reinforcements except for the weave structure. In was found that the phenomenon of strength transfer from tow to composite is negatively influenced by the crimp. In general the strength transfer coefficients have higher values for dry reinforcements and afterwards due to resin impregnation the values drop.

    Two anthraquinonic dyes, C.I. Acid Blue 225 and C.I. Acid Violet 109, were used as models to explore the feasibility of using the horseradish peroxidase enzyme (HRP) in the practical decolorization of anthraquinonic dyes in wastewater. The influence of process parameters such as enzyme concentration, hydrogen peroxide concentration, temperature, dye concentration, and pH was examined. The pH and temperature activity profiles were similar for decolorization of both dyes. Under the optimal conditions, 94.7% of C.I. Acid Violet 109 from aqueous solution was decolorized (treatment time 15 min, enzyme concentration 0.15 IU/mL, hydrogen peroxide concentration 0.4 mM, dye concentration 30 mg/L, pH 4, and temperature 24°C) and 89.36% of C.I. Acid Blue 225 (32 min, enzyme concentration 0.15 IU/mL, hydrogen peroxide concentration 0.04 mM, dye concentration 30 mg/L, pH 5, and temperature 24°C). The mechanism of both reactions has been proven to follow the two substrate ping-pong mechanism with substrate inhibition, revealing the formation of a nonproductive or dead-end complex between dye and HRP or between H2O2 and the oxidized form of the enzyme. Both chemical oxygen demand and total organic carbon values showed that there was a reduction in toxicity after the enzymatic treatment. This study verifies the viability of use of horseradish peroxidase for the wastewaters treatment of similar anthraquinonic dyes.

    This paper investigates the relationship between open hole tensile strength and distance between a hole and a stitch in a textile composite material. Tension tests were completed on various specimens with widths of 1 in., 2 in., 3 in. and a constant width to hole diameter ratio of 4. The composites tested were warp knits with AS4 fibers and 3501-6 resin. Test results show a small percent change of net strength with stitch location. However, due to the large scatter in data, the small 6% change in net strength is considered negligible.

  11. Textile dye degradation using nano zero valent iron: A review.

    Science.gov (United States)

    Raman, Chandra Devi; Kanmani, S

    2016-07-15

    Water soluble unfixed dyes and inorganic salts are the major pollutants in textile dyeing industry wastewater. Existing treatment methods fail to degrade textile dyes and have limitations too. The inadequate treatment of textile dyeing wastewater is a major concern when effluent is directly discharged into the nearby environment. Long term disposal threatens the environment, which needs reclamation. This article reviews the current knowledge of nano zero valent iron (nZVI) technique in the degradation of textile dyes. The application of nZVI on textile dye degradation is receiving great attention in the recent years because nZVI particles are highly reactive towards the pollutant, less toxic, and economical. The nZVI particles aggregate quickly with respect to time and the addition of supports such as resin, nickel, zinc, bentonite, biopolymer, kaolin, rectorite, nickel-montmorillonite, bamboo, cellulose, biochar, graphene, and clinoptilolite enhanced the stability of iron nanoparticles. Inclusion of supports may in turn introduce additional toxic pollutants, hence green supports are recommended. The majority of investigations concluded dye color removal as textile dye compound removal, which is not factual. Very few studies monitored the removal of total organic carbon and observed the products formed. The results revealed that partial mineralization of the textile dye compound was achieved. Instead of stand alone technique, nZVI can be integrated with other suitable technique to achieve complete degradation of textile dye and also to treat multiple pollutants in the real textile dyeing wastewater. It is highly recommended to perform more bench-scale and pilot-scale studies to apply this technique to the textile effluent contaminated sites.

  12. A wearable tracking device inkjet-printed on textile

    2017-05-20

    Despite the abundance of localization applications, the tracking devices have never been truly realized in E-textiles. Standard printed circuit board (PCB)-based devices are obtrusive and rigid and hence not suitable for textile based implementations. An attractive option would be direct printing of circuit layout on the textile itself, negating the use of rigid PCB materials. However, high surface roughness and porosity of textiles prevents efficient and reliable printing of electronics on textile. In this work, by printing an interface layer on the textile first, a complete localization circuit integrated with an antenna has been inkjet-printed on the textile for the first time. Printed conductive traces were optimized in terms of conductivity and resolution by controlling the number of over-printed layers. The tracking device determines the wearer\\'s position using WiFi and this information can be displayed on any internet-enabled device, such as smart phone. The device is compact (55mm×45mm) and lightweight (22g with 500mAh battery) for people to comfortably wear it and can be easily concealed in case discretion is required. The device operates at 2.4GHz communicated up to a distance of 55m, with localization accuracy of up to 8m.

  13. Particle-Based Geometric and Mechanical Modelling of Woven Technical Textiles and Reinforcements for Composites

    Science.gov (United States)

    Samadi, Reza

    Technical textiles are increasingly being engineered and used in challenging applications, in areas such as safety, biomedical devices, architecture and others, where they must meet stringent demands including excellent and predictable load bearing capabilities. They also form the bases for one of the most widespread group of composite materials, fibre reinforced polymer-matrix composites (PMCs), which comprise materials made of stiff and strong fibres generally available in textile form and selected for their structural potential, combined with a polymer matrix that gives parts their shape. Manufacturing processes for PMCs and technical textiles, as well as parts and advanced textile structures must be engineered, ideally through simulation, and therefore diverse properties of the textiles, textile reinforcements and PMC materials must be available for predictive simulation. Knowing the detailed geometry of technical textiles is essential to predicting accurately the processing and performance properties of textiles and PMC parts. In turn, the geometry taken by a textile or a reinforcement textile is linked in an intricate manner to its constitutive behaviour. This thesis proposes, investigates and validates a general numerical tool for the integrated and comprehensive analysis of textile geometry and constitutive behaviour as required toward engineering applications featuring technical textiles and textile reinforcements. The tool shall be general with regards to the textiles modelled and the loading cases applied. Specifically, the work aims at fulfilling the following objectives: 1) developing and implementing dedicated simulation software for modelling textiles subjected to various load cases; 2) providing, through simulation, geometric descriptions for different textiles subjected to different load cases namely compaction, relaxation and shear; 3) predicting the constitutive behaviour of the textiles undergoing said load cases; 4) identifying parameters

    In this study, electron beam accelerator (EB) was used to treat textiles wastewater from Rawang Industrial Park, Selangor. The objectives were to determine effective energy, beam current and absorbed dose required for decoloration and degradation of the textiles effluent. The textiles effluent was irradiated in a batch with various energy of 1MeV to 3MeV at constant beam current of 30mA. It was observed that removal of color and COD increases with higher beam energy. The EB energy of 1MeV effectively to removed 58% color and 19% COD. For textile effluent sample irradiated at fix energy of 1MeV and 3Mev but at different beam current 10mA, 20mA and 30mA. It was observed that removal of color and COD increases with the increased of beam current at each energy. However removal of color was significantly better at 1Mev as compared to 3Mev. In the case of textiles effluent, irradiated at doses of 17, 20,25,30, 35, 100 and 200kGy using 30 kW power of EB (1Mev, 30mA), results shows removal of BOD{sub 5}, COD and color were in the range 9%-33%, 14%-38% and 43%-78% respectively.

    To reduce pruritus and colonization with Staphylococcus aureus, textiles containing silver are increasingly used as therapeutic option for patients with atopic dermatitis (AD). While wearing such textiles, the contained silver is in close contact with the patient's skin. The silver serves two purposes: to reduce bacterial colonization of the skin, and to prevent contamination of the textile with ensuing growth of microorganisms. It is unknown whether the silver impregnation is able to reduce bacterial contamination of the textile during wearing and to prevent bacterial growth within the textile. The aim of this study was to investigate the bacterial contamination in textiles containing silver versus placebo worn by patients with AD and to determine the efficacy of processing worn textiles by manual and machine-based washing. Additionally, the effect of silver textiles on S. aureus and total bacterial counts colonizing the skin of AD patients was analyzed. The reduction factor of silver textile compared to placebo was 0.5 log steps against S. aureus and 0.4 log steps against total bacteria. Silver textiles exhibited significantly less S. aureus as well as total bacterial colonization after 2 days of wearing without washing, as compared with a placebo textile. On placebo textiles 385.6 +/- 63.5 CFU total bacteria and 236.5 +/- 49.9 CFU S. aureus, and on silver textiles 279.9 +/- 78.7 CFU total bacteria and 119.3 +/- 39.4 CFU S. aureus were found on the inner side of the textiles facing the neurodermitis lesions. However, the unexpectedly high residual contamination despite the silver exposure represents a potential risk as recontamination source of S. aureus that could maintain the proinflammatory process in AD. This contamination is nearly completely eliminated by machine-based washing at 60 degrees C using conventional washing powder. AD patients wearing silver textiles should change their used clothes at least daily and wash them in a washing machine at 60 degrees

    Full Text Available In the textiles production industry it is more and more common to advertise new textiles, especially for sportswear, by claiming their ability to emit IR radiation in the long wave band at a higher degree with respect to normal clothes, that is highly beneficial to improve sporting performances. Three textiles are compared, one normal and two “special,” with Ag+ ions and carbon powder added, with different colors. The emissivity of the textiles has been measured to determine if it is increased in the “special” textiles with respect to the normal one. No substantial increase has been noticed. Nonetheless, the test implied some nonstandard procedures due to the semitransparent nature of the textiles, in comparison with the normal procedure that is commonly used on opaque surfaces.

    Textile composites have the advantage over laminated composites of a significantly greater damage tolerance and resistance to delamination. Currently, a disadvantage of textile composites is the inability to examine the details of the internal response of these materials under load. Traditional approaches to the study fo textile based composite materials neglect many of the geometric details that affect the performance of the material. The present three dimensional analysis, based on the representative volume element (RVE) of a plain weave, allows prediction of the internal details of displacement, strain, stress, and failure quantities. Through this analysis, the effect of geometric and material parameters on the aforementioned quantities are studied.

  6. Computational modeling and impact analysis of textile composite structures

    Science.gov (United States)

    Hur, Hae-Kyu

    This study is devoted to the development of an integrated numerical modeling enabling one to investigate the static and the dynamic behaviors and failures of 2-D textile composite as well as 3-D orthogonal woven composite structures weakened by cracks and subjected to static-, impact- and ballistic-type loads. As more complicated modeling about textile composite structures is introduced, some of homogenization schemes, geometrical modeling and crack propagations become more difficult problems to solve. To overcome these problems, this study presents effective mesh-generation schemes, homogenization modeling based on a repeating unit cell and sinusoidal functions, and also a cohesive element to study micro-crack shapes. This proposed research has two: (1) studying behavior of textile composites under static loads, (2) studying dynamic responses of these textile composite structures subjected to the transient/ballistic loading. In the first part, efficient homogenization schemes are suggested to show the influence of textile architectures on mechanical characteristics considering the micro modeling of repeating unit cell. Furthermore, the structures of multi-layered or multi-phase composites combined with different laminar such as a sub-laminate, are considered to find the mechanical characteristics. A simple progressive failure mechanism for the textile composites is also presented. In the second part, this study focuses on three main phenomena to solve the dynamic problems: micro-crack shapes, textile architectures and textile effective moduli. To obtain a good solutions of the dynamic problems, this research attempts to use four approaches: (I) determination of governing equations via a three-level hierarchy: micro-mechanical unit cell analysis, layer-wise analysis accounting for transverse strains and stresses, and structural analysis based on anisotropic plate layers, (II) development of an efficient computational approach enabling one to perform transient

    The goals of this study were to determine the concentrations of perfluorooctane sulfonate (PFOS) and perfluorooctanoic acid (PFOA) in textiles and to determine PFOS and PFOA contamination in textile washing water. Quantification analysis was performed by high performance liquid chromatography coupled with tandem mass spectrometry. Analysis of 32 textile samples by methanol extraction revealed that the average concentrations of PFOS and PFOA were 0.18 µg m(-2) (0.02 to 0.61 µg m(-2)) and 2.74 µg m(-2) (0.31 to 14.14 µg m(-2)), respectively. Although the average concentration of PFOS found in textile samples was below European Union (EU) Commission regulations (textile samples had PFOA concentrations exceeding 1 µg m(-2). Thus, based on these results, the concentration of PFOA in products should also be regulated. Experiments on PFOS and PFOA leaching into washing water were conducted. The maximum concentrations of PFOS and PFOA were measured after the first washing; the concentrations gradually decreased with each subsequent washing. PFOS and PFOA migrated from textiles and were released into the environment, with disappearance percentages of 29.8% for PFOS and 99% for PFOA. The data presented in this study showed that textiles could be a significant direct and indirect source of PFOS and PFOA exposure for both humans and the environment.

    Full Text Available One of the main socio-economic problems in Russia is the high cost and the poor condition of housing.Such goals as cost reduction, reducing installation time and increasing the service life of structures are accomplishing by creating new technologies of erecting buildings and developing ways ofquickconstruction, using different types of fixed formwork. One of themis textstone.Textstone is an artificial construction stone, containing on the outer surface the reinforcing fine-mesh shell with multifunctional properties, formed by the interwoven threads of a vigorous fixed formwork textile material (basalt, linen, silica and other glass yarns adhered by binding material. The innovative construction technology of production and installation of a new generation of textstone buildings has been registered as a brand TextStone. The fundamental difference between texstone and reinforced concrete and all known building materials is that the whole outer surface of solidified light binders is protected by strong, vigorous and fixed formwork made from inexpensive textile materials. Manufacturing textile shells allows using it as an internal finishing material, reducing or eliminating the cost of finishing work.The use of fixed textile construction shutters during the construction of buildings has obvious technical, economic, operational, sanitary and environmental benefits: short construction time (from 3 to 10 days, compact packaging and light weight of fabric shells, high fire resistance, frost resistance, ease of engineering services installation in the hollow communicating shells; minimal amount of finishing, roofing, heat and noise insulation works. Texstone is a durable solid monolithic construction that provides high viability and earthquakes, hurricanes wind, solar sultriness and frost resistance. Material complies with all sanitary and environmental requirements. Due to such physical, mechanical, operational, sanitary and ecological characteristics

    Background: Factors that influence exposure to silver particles from the use of textiles are not well understood. Objectives: The aim of this study was to evaluate the influence of product treatment and physiological factors on silver release from two textiles. Methods: Atomic and absorbance spectroscopy, electron microscopy, and dynamic light scattering (DLS) were applied to characterize the chemical and physical properties of the textiles and evaluate silver release in artificial sweat and saliva under varying physiological conditions. One textile had silver incorporated into fiber threads (masterbatch process) and the other had silver nanoparticles coated on fiber surfaces (finishing process). Results: Several complementary and confirmatory analytical techniques (spectroscopy, microscopy, etc.) were required to properly assess silver release. Silver released into artificial sweat or saliva was primarily in ionic form. In a simulated “use” and laundering experiment, the total cumulative amount of silver ion released was greater for the finishing process textile (0.51±0.04%) than the masterbatch process textile (0.21±0.01%); P<0.01. Conclusions: We found that the process (masterbatch vs finishing) used to treat textile fibers was a more influential exposure factor than physiological properties of artificial sweat or saliva.

    3D printing is a rapidly emerging additive manufacturing technology which can offer cost efficiency and flexibility in product development and production. In textile production 3D printing can also serve as an add-on process to apply 3D structures on textiles. In this study the low-cost fused deposition modeling (FDM) technique was applied using different thermoplastic printing materials available on the market with focus on flexible filaments such as thermoplastic elastomers (TPE) or Soft PLA. Since a good adhesion and stability of the 3D printed structures on textiles are essential, separation force and abrasion resistance tests were conducted with different kinds of printed woven fabrics demonstrating that a sufficient adhesion can be achieved. The main influencing factor can be attributed to the topography of the textile surface affected by the weave, roughness and hairiness offering formlocking connections followed by the wettability of the textile surface by the molten polymer, which depends on the textile surface energy and can be specifically controlled by washing (desizing), finishing or plasma treatment of the textile before the print. These basic adhesion mechanisms can also be considered crucial for 3D printing on knitwear.

  17. Idealized textile composites for experimental/analytical correlation

    1994-01-01

    Textile composites are fiber reinforced materials produced by weaving, braiding, knitting, or stitching. These materials offer possible reductions in manufacturing costs compared to conventional laminated composites. Thus, they are attractive candidate materials for aircraft structures. To date, numerous experimental studies have been performed to characterize the mechanical performance of specific textile architectures. Since many materials and architectures are of interest, there is a need for analytical models to predict the mechanical properties of a specific textile composite material. Models of varying sophistication have been proposed based on mechanics of materials, classical laminated plate theory, and the finite element method. These modeling approaches assume an idealized textile architecture and generally consider a single unit cell. Due to randomness of the textile architectures produced using conventional processing techniques, experimental data obtained has been of limited use for verifying the accuracy of these analytical approaches. This research is focused on fabricating woven textile composites with highly aligned and accurately placed fiber tows that closely represent the idealized architectures assumed in analytical models. These idealized textile composites have been fabricated with three types of layer nesting configurations: stacked, diagonal, and split-span. Compression testing results have identified strength variations as a function of nesting. Moire interferometry experiments are being used to determine localized deformations for detailed correlation with model predictions.

    Full Text Available Texture semantics, which is the kind of feelings that the texture feature of an image would arouse in people, is important in texture analysis. In this paper, we study the relationship between texture semantics and textile images, and propose a novel parametric mapping model to predict texture semantics from textile images. To represent rich texture semantics and enable it to participate in computation, 2D continuous semantic space, where the axes correspond to hard-soft and warm-cool, is first adopted to quantitatively describe texture semantics. Then texture features of textile images are extracted using Gabor decomposition. Finally, the mapping model between texture features and texture semantics in the semantic space is built using three different methods: linear regression, k-nearest neighbor (KNN and multi-layered perceptron (MLP. The performance of the proposed mapping model is evaluated with a dataset of 1352 textile images. The results confirm that the mapping model is effective and especially KNN and MLP reach the good performance. We further apply the mapping model to two applications: automatic textile image annotation with texture semantics and textile image search based on texture semantics. The subjective experimental results are consistent with human perception, which verifies the effectiveness of the proposed mapping model. The proposed model and its applications can be applied to various automation systems in commercial textile industry.

    Full Text Available During the transition to a market economy, the state of many countries’ economies and the international textile industry face considerable challenges. There are many uncertainties surrounding the global textile market, exacerbated by gloomy predictions that for a decade should have been eliminated, resulting in “free” trade flows. There is no doubt that manufacturers which have created niche markets will be better positioned to compete in the global marketplace and achieve higher margins for products while yielding greater profitability. This paper is an introduction of a reasearch that examines how some textile market niches have evolved. The goal of this paper is research and the role that textile niche markets will play by 2025. Specific objectives are: to give a broad overview of various trade theories, including classical, neo-classical, post-neo-classical, and modern, in order to determine what are the possibilities for development and protection. In particular, emphasis will be focused the special problems, due to the vector exchanges and commercial conjuncture, to illustrate how traditional marketing methods differ from market to market and to examine what role will play niche markets in the textiles industry and textile apparel industry in 2050. The results of this research study will help formulate a business strategy that can be used in market capitalization and will provide a framework for research for textile researchers at a global level.

    A low velocity impact study of aircraft tire rubber on 3D textile-reinforced composite plates was performed experimentally and numerically. In contrast to regular unidirectional composite laminates, no delaminations occur in such a 3D textile composite. Yarn decohesions, matrix cracks and yarn ruptures have been identified as the major damage mechanisms under impact load. An increase in the number of 3D warp yarns is proposed to improve the impact damage resistance. The characteristic of a rubber impact is the high amount of elastic energy stored in the impactor during impact, which was more than 90% of the initial kinetic energy. This large geometrical deformation of the rubber during impact leads to a less localised loading of the target structure and poses great challenges for the numerical modelling. A hyperelastic Mooney-Rivlin constitutive law was used in Abaqus/Explicit based on a step-by-step validation with static rubber compression tests and low velocity impact tests on aluminium plates. Simulation models of the textile weave were developed on the meso- and macro-scale. The final correlation between impact simulation results on 3D textile-reinforced composite plates and impact test data was promising, highlighting the potential of such numerical simulation tools.

    Nowadays most plant textiles used for clothing and household are made of cotton and viscose. Before the 19th century however, plant textiles were mainly made from locally available raw materials, in Scandinavia these were: nettle, hemp and flax. It is generally believed that in Viking and early Middle Ages Scandinavia hemp was used only for coarse textiles (i.e. rope and sailcloth). Here we present an investigation of 10 Scandinavian plant fibre textiles from the Viking and Early Middle Ages, believed to be locally produced. Up till now they were all believed to be made of flax. We show that 4 textiles, including two pieces of the famous Överhogdal Viking wall-hanging are in fact made with hemp (in three cases hemp and flax are mixed). This indicates that hemp was important, not only for coarse but also for fine textile production in Viking and Early Middle Ages in Scandinavia.

    Full Text Available This case study was developed from an actual scenario by Dr. Steve Leybourne of Boston University.  The case documents the historical evolution of an organization, and has been used successfully in courses dealing with organizational and cultural change, and the utilization of ‘soft skills’ in project-based management. This is a short case, ideal for classroom use and discussion.  The issues are easily accessible to students, and there is a single wide ranging question that allows for the inclusion of many issues surrounding strategic decision-making, and behavioural and cultural change. Alpha was one of the earlier companies in the USA to invest in large, edge-of-town superstores, with plentiful free vehicle parking, selling food and related household products. Alpha was created in the 1950s as a subsidiary of a major publicly quoted retail group.  It started business by opening a string of very large discount stores in converted industrial and warehouse premises in the south of the United States. In the early days shoppers were offered a limited range of very competitively priced products. When Alpha went public in 1981 it was the fourth largest food retailer in the US, selling an ever-widening range of food and non-food products.  Its success continued to be based on high volume, low margins and good value for money, under the slogan of ‘Alpha Price.’

  9. Design of Safer Flame Retardant Textiles through Inclusion Complex Formation with Cyclodextrins: A Combined Experimental and Modeling Study

    Science.gov (United States)

    Zhang, Nanshan

    Triphenyl phosphate (TPP) is widely used as a phosphorus flame retardant. It is also one component of a commercial flame retardant mixture known as Firemaster 550. TPP is likely to be released into the environment due to its high volatility and has been detected at a concentration as high as 47,000 ng/m3 in air. Recent studies have also indicated that FRs like TPP could contribute to obesity and osteoporosis in humans. Cyclodextrins (CDs) are enzymatic degradation products of starch and consist of several (alpha-1,4)-linked alpha-Dglucopyranose units. CDs own a hydrophilic outside and a hydrophobic inner cavity, which enables the formation of non-covalently bonded cyclodextrin inclusion complexes (CD-ICs) with a vast array of molecules. We hypothesize that the formation of inclusion complexes between TPP and cyclodextrins will reduce its exposure yet also retain flame retarding properties of TPP, since the formation of FR-CD-ICs is expected to eliminate unnecessary loss of FRs, especially volatile FR compounds like TPP, and release them only during a fire when they are actually needed. After creating the TPP-beta-CD-IC, we applied it to polyethylene terephthalate (PET) films by a hot press technique. Flame tests indicated TPP-beta-CD-IC exhibited flame resistant performance matching that of neat TPP, even though much less TPP was contained in its beta-CD-IC. Incorporation of FRs and other chemical additives into textile substrates in the form of their crystalline CD-ICs is a promising way to reduce the exposure of hazardous chemicals to humans and to our environment while not impacting their efficacy. Two other parent CDs (alpha-CD and gamma-CD) were applied and their abilities to form ICs with guest TPP were studied. Results from a series of characterization methods, including FTIR, DSC, TGA, XRD and NMR indicated the successful synthesis of TPP-gamma-CD-IC via two routes. However, alpha-CD appears unable to form an IC with TPP, which is likely attributable to a

    Full Text Available Background and Design: Our aim was to determine the frequency of contact sensitization to textile materials and the most common textile allergens in patients who work in the textile industry and have been diagnosed with allergic contact dermatitis (ACD. Materials and Methods: Fifty textile industry workers, who attended our outpatient clinic with the diagnosis of ACD, between October 2005-December 2009, were enrolled in this study. While 50 patients were tested with the Thin layer-Rapid-Use-Epicutaneous (TRUE test, 36 patients were tested with the TRUE test and textile series allergen. The results were analyzed as percentage and statistically. Results: Of the 50 patients, 34 (68% were men, 16 (32% were women. The mean of the subjects was 37.4 years. In 38.8 of the patients in whom TRUE test and textile series allergens applied together, at least one allergic reaction was seen. Of the 36 patients applied textile series in addition to the TRUE test, 33.3% of patients had positive reaction to only textile allergens, 2.7% to only standard series allergens, and 2.7% of subjects had positive reaction to both textile series and standard series allergens. 76.9% of these reactions were to dyes, 15.3% to resins and 7.6% of them were to both of them. Disperse blue 106 (8.3%, acid red 359 (8.3% and disperse red 17 (5.5% were the most positive reaction seen dyes. 18% of 50 patients tested with TRUE test alone showed at least one positive reaction. The most common standard series allergens were nickel sulphate (6% and ethylenediamine dihydrocloride (6%. Both the relationship between atopy and contact sensitization and also the relationship with hand localization and contact sensitization to textile allergens were not statistically significant. Conclusion: In occupational textile dermatitis, contact sensitization is common and especially seen to disperse dyes. For the contact sensitization to textile materials, standard series allergens cannot be adequate in

    The NASA Langley Research Center is conducting and sponsoring research to explore the benefits of textile reinforced composites for civil transport aircraft primary structures. The objective of this program is to develop and demonstrate the potential of affordable textile reinforced composite materials to meet design properties and damage tolerance requirements of advanced aircraft structures. In addition to in-house research, the program includes major participation by the aircraft industry and aerospace textile companies. The major program elements include development of textile preforms, processing science, mechanics of materials, experimental characterization of materials, and development and evaluation of textile reinforced composite structural elements and subcomponents. The NASA Langley in-house research is focused on science-based understanding of resin transfer molding (RTM), development of powder-coated towpreg processes, analysis methodology, and development of a performance database on textile reinforced composites. The focus of the textile industry participation is on development of multidirectional, damage-tolerant preforms, and the aircraft industry participation is in the areas of innovative design concepts, cost-effective fabrication, and testing of textile reinforced composite structural elements and subcomponents. Textile processes such as 3-D weaving, 2-D and 3-D braiding, and knitting/stitching are being compared with conventional laminated tape processes for improved damage tolerance. Through-the-thickness reinforcements offer significant damage tolerance improvements. However, these gains must be weighed against potential loss in in-plane properties such as strength and stiffness. Analytical trade studies are underway to establish design guidelines for the application of textile material forms to meet specific loading requirements. Fabrication and testing of large structural components are required to establish the full potential of textile

    Full Text Available The paper presents arguments and examples regarding the need to reuse, sort, manage and recycle more efficiently the textile wastes. Waste are increasing from a quantitative point of view and represent a major problem in each European country and the textile waste represent 5% of the total quantity of waste at a global level. It is estimated that about 95% of what it reaches the landfill could be reused so that the necessity of recycling is obvious. The constant need of transforming the wastes into by-products represents a priority because the textile waste have a special characteristic in the way that they can be reused or even repurposed. The paper also syhthesizes the legislation that makes reference to the textile waste, their classification and the obligations of the local community members, natural or legal persons. It is also presents the current situation of the textile waste with respect to Romania and Bihor county, but there are also presented other numerous cases, examples and situations in which the waste is recovered/collected properly. The examples have the role of showing and emphasizing the concerns of some companies, brands, institutions or local authorities, specialists and specialized personnel within the agencies of environmental protection to encourage recycling or reuse of the textile products that are inappropriately considered as wastes. The information for this paper was collected from literature, from the Agency of Environmental Protection Bihor and on the Internet.

    Full Text Available Supplier selection, inventory management and optimal lot sizing has been one of the most important issues in many industries especially in production planning issues associated with texture industry. The proposed model of this paper first introduces an algorithm to choose the best supplier and it determines the optimal lot size using discount strategy. The proposed model of this paper considers different influencing factors such as location, quality of materials, cost, and mutual trust for supplier selection, determines their relative importance weights and then a discounting method is used to determine the ordering lot-size. The preliminary results indicate that the proposed model of this paper can be implemented in texture industry, very efficiently since the ordering discount policy is not sensitive to changes on inventory holding and setup expenditures.

    2016-06-01

    This study addresses the release of total silver (Ag) and silver nanoparticles (Ag-NPs) from textiles into artificial sweat, particularly considering the functionalization technology used in textile finishing. Migration experiments were conducted for four commercially available textiles and for six laboratory-prepared textiles. Two among these lab-prepared textiles represent materials in which Ag-NPs were embedded within the textile fibers (composites), whereas the other lab-prepared textiles contain Ag particles on the respective fiber surfaces (coatings). The results indicate a smaller release of total Ag from composites in comparison to surface-coated textiles. The particulate fraction determined within the artificial sweat was negligible for most textiles, meaning that the majority of the released Ag is present as dissolved Ag. It is also relevant to note that nanotextiles do not release more particulate Ag than conventional Ag textiles. The results rather indicate that the functionalization type is the most important parameter affecting the migration. Furthermore, after measuring different Ag-NP types in their pristine form with inductively coupled plasma mass spectrometry in the single particle mode, there is evidence that particle modifications, like surface coating, may also influence the dissolution behavior of the Ag-NPs in the sweat solutions. These factors are important when discussing the likelihood of consumer exposure.

The obtaining of environmental licence for Romanian companies that produce textile products is related to elaboration and implementation of a modern system for an environmental management, that consist in utilization of ecological technologies for finishing, in diminution the water and energy consumption, cleaning of waste waters, reutilization of cleaned waters, sustainable management of wastes. In this study, the surfactant categories used in the textile industry that fulfil the conditions of environment protection, are presented. Some exemplifications were made involving the existing surfactants in Romanian textile industry, obtained from both domestic and external production. Also, some recommendation are suggested regarding the utilization of surfactants manufactured from either vegetal oils or chemical/petrochemical wastes, with similar properties as those from import having decreased prices an that affect as small as possible the environment.

    Full Text Available Textile manufacturing consumes a considerable amount of water in its manufacturing processes. The water is primarily utilized in the dyeing and finishing operations of the textile establishments. Considering both the volume generated and the effluent composition, the textile industry wastewater is rated as the most polluting among all industrial sectors. In this study a combined anaerobic-aerobic reactor was operated continuously for treatment of textile wastewater. Cosmo balls were used to function as growth media for microorganisms in anaerobic reactor. Effect of pH, dissolved oxygen, and organic changes in nitrification and denatrification process were investigated. The results indicated that over 84.62% ammonia nitrogen and about 98.9% volatile suspended solid (VSS removal efficiency could be obtained. Dissolved oxygen (DO, pH were shown to have only slight influences on the nitrification process; and for each 10% removal of nitrogen, only 3% of pH changes were achieved.

    2010-10-01

    The environmental aspects of textiles are very complex and include production, processing, transport, usage, and recycling. Textiles are made from a variety of materials and can contain a large number of chemicals. Chemicals are used during production of fibres, for preservation and colouring and they are released during normal wear and during washing. The aim of this study was to investigate the release to water of toxic chemicals from various textiles. Altogether 52 samples of textiles made from cotton (21), linen (4), cotton and linen (7), cellulose (3), synthetic fibres (7), cotton and synthetic fibres (8) and wool (2). Seven were eco-labelled. All textiles were cut into squares and placed into Petri dishes with 50 ml ISO test medium in a concentration series (4-256 cm(2)/50 ml) and tested for acute toxicity to Daphnia magna. Estimated EC50s were converted into weight/volume, and 48-h EC50s ranged between 182 g/L. It was not possible to detect any difference between fibre type and toxicity (ANOVA), but a significantly higher toxicity was found for printed versus unprinted cotton and cotton/linen textiles, while the opposite was found for synthetic textiles. Eco-labelled products were evenly distributed on a toxicity scale, which means that eco-labelling in its present form does not necessarily protect users or the environment from exposure to toxic chemicals. Therefore, the results from the present study suggest that bioassays and toxicity tests should become an integrated part of textile environmental quality control programs.

    This paper presents results of mechanical tests on a prototype of an innovative structural strengthening in form of self-monitoring fabric. Smart textile employs carbon fibers conductivity for measuring strains while monitoring changes of electric resistance under increasing load. A general solution was tested in a series of calibrating tests on strengthening of small size concrete slabs. Promising results of simple specimen, has encouraged the research team to perform the next tests using mastered carbon fibre reinforced fabric. Main tests were performed on natural scale RC beam. Smart textile proved its efficiency in both: strengthening and monitoring of strains during load increase. New strengthening proposal was given 10% increase of loading capacity and the readings of strain changes were similar to those obtained in classical methods. In order to calibrate the prototype and to define range limits of solution usability, textile sensor was tested in areas of large deformations (timber beam) and aswell as very small strains (bridge bearing block). In both cases, the prototype demonstrated excellent performance in the range of importance for structural engineering. This paper also presents an example of use of the smart strengthening in situ, in a real life conditions.

    2002-05-01

    A meta-analysis of epidemiologic studies for textile industry workers was undertaken in an attempt to evaluate whether the cancer risk varies within the textile industry in relation to the job held or the textile fiber used. We combined studies published up until 1990, when an ad hoc IARC Monograph was issued, and those published after 1990 with the aim of appreciating evidence of reversing trends in cancer risk. Observed and expected cases reported in the original studies were summed up and the totals were divided to obtain a pooled relative risk (PRR) with a 95% confidence interval (CI) estimated with a fixed-effect model. We calculated a chi-square test (chi2) of heterogeneity among studies. When PRR and chi2 were both significant, PRR and CI were calculated with a random-effect model and the source of heterogeneity was investigated. Lung cancer risk was around 0.4 in the first study on cotton workers published in 1936, around 0.7 in subsequent studies, mostly published in the 1970s and 1980s, and around 1.0 in the last studies published in the 1990s. Papers published in the 1970s and 1980s produced consistent risk estimates for lung cancer risk, which was significantly lower than 1.0 in workers exposed to cotton (PRR = 0.77; CI = 0.69-0.86) and wool dust (0.71; 0.50-0.92), as well as in carders and fiber preparers (0.73; 0.54-0.91), weavers (0.71; 0.56-0.85), and spinners and weavers (0.78; 0.66-0.91). Lung cancer PRRs did not significantly deviate from 1.0 in textile workers using synthetic fibers or silk, and in dyers. Increased PRRs were found for sinonasal cancer in workers exposed to cotton dust, and in workers involved in spinning or weaving (4.14; 1.80-6.49). PRR was 1.46 (1.10-1.82) for cancer of the digestive system in textile workers using synthetic fibers or silk, and 1.34 (1.10-1.59) for colorectal cancer in spinners and weavers. The increased bladder cancer PRR in dyers (1.39; 1.07-1.71) is generally attributed to textile dye exposure. In studies

    Bond, G G

    1993-01-01

    The need to notify individuals of a possible health risk from their past exposure to potentially hazardous agents frequently extends beyond workers to include community groups. The issues to consider in community notification are frequently similar to those that are important for worker notification but may include some that are unique. This case study traces the evolution of one company's strategy for communicating with the public about possible dioxin contamination associated with its operations. Early communications tended to emphasize the technical aspects of the issues in the fashion of scientists talking to other scientists. This was interpreted by some to be symptomatic of an arrogant and uncaring attitude. Beginning in the early 1980s, the company's management recognized the need to reach out to a variety of audiences on multiple levels, and shifted to a more comprehensive communications strategy. A similar shift is now occurring throughout the chemical manufacturing industry as top managers realize that, if they expect to continue to operate, they must become more accountable and responsive to the public.

    In a double murder investigation, the victims were found after a prolonged stay in a drainage canal. In spite of the expectations, fibre examination established a multitude of primary and secondary transferred fibres. One of these fibre types was a colourless polyester fibre possessing a blue coloured molten fibre end. These matched one of the types present in the suspect's blue denim trousers. The aim of this study was to verify the rarity of this peculiar fibre type and more precisely its presence in blue denim textiles. Over five hundred different blue jeans textiles were examined and only one of these presented exactly the same type. The comparison involved microscopy, microspectrophotometry in the visible range and Raman spectroscopy. The results indicate this fibre type is extremely rare in a blue jeans fabrics and that "standard" blue denim should not be disregarded in case work.

    Textile effluent is one of the main contributors of water pollution and it adversely affects fauna and flora. Constructed wetland is a promising approach to remediate the industrial effluent. The detoxification of industrial effluent in a constructed wetland system may be enhanced by applying beneficial bacteria that are able to degrade contaminants present in industrial effluent. The aim of this study was to evaluate the influence of inoculation of textile effluent-degrading endophytic bacteria on the detoxification of textile effluent in a vertical flow constructed wetland reactor. A wetland plant, Typha domingensis, was vegetated in reactor and inoculated with two endophytic bacterial strains, Microbacterium arborescens TYSI04 and Bacillus pumilus PIRI30. These strains possessed textile effluent-degrading and plant growth-promoting activities. Results indicated that bacterial inoculation improved plant growth, textile effluent degradation and mutagenicity reduction and were correlated with the population of textile effluent-degrading bacteria in the rhizosphere and endosphere of T. domingensis. Bacterial inoculation enhanced textile effluent-degrading bacterial population in rhizosphere, root and shoot of T. domingensis. Significant reductions in COD (79%), BOD (77%) TDS (59%) and TSS (27%) were observed by the combined use of plants and bacteria within 72 h. The resultant effluent meets the wastewater discharge standards of Pakistan and can be discharged into the environment without any risks. This study revealed that the combined use of plant and endophytic bacteria is one of the approaches to enhance textile effluent degradation in a constructed wetland system.

    Bioassays for cyto-genotoxicity assessments are generally not required in current textile industry effluent discharge management regulations. The present study applied in vivo plant and fish based toxicity tests viz. Allium cepa test system and Oreochromis niloticus erythrocyte based comet assay and nuclear abnormalities tests in combination with physico-chemical analysis for assessing potential cytotoxic/genotoxic impacts of treated textile industry effluents reaching a major river (Kelani River) in Sri Lanka. Of the treated effluents tested from two textile industries, color in the Textile industry 1 effluents occasionally and color, biochemical oxygen demand and chemical oxygen demand in the Textile industry 2 effluents frequently exceeded the specified Sri Lankan tolerance limits for discharge of industrial effluents into inland surface waters. Exposure of A. cepa bulbs to 100% and 12.5% treated effluents from both industries resulted in statistically significant root growth retardation, mito-depression, and induction of chromosomal abnormalities in root meristematic cells in comparison to the dilution water in all cases demonstrating cyto-genotoxicity associated with the treated effluents. Exposure of O. niloticus to the 100% and 12.5% effluents, resulted in erythrocytic genetic damage as shown by elevated total comet scores and induction of nuclear abnormalities confirming the genotoxicity of the treated effluents even with 1:8 dilution. The results provide strong scientific evidence for the crucial necessity of incorporating cyto-genotoxicity impact assessment tools in textile industry effluent management regulations considering human health and ecological health of the receiving water course under chronic exposure.

    Full Text Available The common textile architecture/geometry are woven, braided, knitted, stitch boded, and Z-pinned. Fibres in textile form exhibit good out-of-plane properties and good fatigue and impact resistance, additionally, they have better dimensional stability and conformability. Besides the nature of the textile, the architecture has a great role in the mechanical behaviour and mechanisms of damage in textiles, therefore damage mechanisms and mechanical performance in structural applications textiles have been a major concern. Mechanical damage occurs to a large extent during the service lifetime consequently it is vital to understand the material mechanical behaviour by identifying its mechanisms of failure such as onset of damage, crack generation and propagation. In this work, textiles of different architecture were used to manufacture epoxy based composites in order to study failure events under tensile load by using acoustic emission technique which is a powerful characterization tool due to its link between AE data and fracture mechanics, which makes this relation a very useful from the engineering point of view.

Textile dyes pollutants are being released to the environment at various stages of operation therefore it is necessary that the pollutants are treated before discharge using zeolite with and without alum. A study was carried out to compare the effectiveness of treatment using zeolite with and without alum for the removal of heavy metals (Pb, Cu, Cd, Cr in textile effluent. The concentrations of these heavy metals in the textile wastewater samples were reduced to more than 50 percent after treating with zeolite. The sequence in increasing order of removal efficiency of these heavy metals using zeolite was Cd < Pb < Cr < Cu. When the textile wastewater sample was treated using zeolite and 10 mg/L of alum, 80% of the heavy metals (Cd and Cu were removed. The most effective treatment prior to removal of heavy metals from textile wastewater sample is by using zeolite with the addition of 10 mg/L of alum as flocculants.

    Full Text Available BACKGROUND: Occupational exposure to endotoxin is associated with decrements in pulmonary function, but how much variation in this association is explained by genetic variants is not well understood. OBJECTIVE: We aimed to identify single nucleotide polymorphisms (SNPs that are associated with the rate of forced expiratory volume in one second (FEV1 decline by a large scale genetic association study in newly-hired healthy young female cotton textile workers. METHODS: DNA samples were genotyped using the Illumina Human CVD BeadChip. Change rate in FEV1 was modeled as a function of each SNP genotype in linear regression model with covariate adjustment. We controlled the type 1 error in study-wide level by permutation method. The false discovery rate (FDR and the family-wise error rate (FWER were set to be 0.10 and 0.15 respectively. RESULTS: Two SNPs were found to be significant (P<6.29×10(-5, including rs1910047 (P = 3.07×10(-5, FDR = 0.0778 and rs9469089 (P = 6.19×10(-5, FDR = 0.0967, as well as other eight suggestive (P<5×10(-4 associated SNPs. Gene-gene and gene-environment interactions were also observed, such as rs1910047 and rs1049970 (P = 0.0418, FDR = 0.0895; rs9469089 and age (P = 0.0161, FDR = 0.0264. Genetic risk score analysis showed that the more risk loci the subjects carried, the larger the rate of FEV1 decline occurred (P trend = 3.01×10(-18. However, the association was different among age subgroups (P = 7.11×10(-6 and endotoxin subgroups (P = 1.08×10(-2. Functional network analysis illustrates potential biological connections of all interacted genes. CONCLUSIONS: Genetic variants together with environmental factors interact to affect the rate of FEV1 decline in cotton textile workers.

    Full Text Available The photocatalytic degradation of synthetic textile dye CI Basic Yellow 28 (BY28 in water, using recently synthesized P160 TiO2 based catalyst, under Osram ultra-vitalux® lamp (300 W light, was studied. The effect of the operational parameters such as initial concentration of catalyst, initial dye concentration and pH was studied. Salt effect was also investigated (NaCl, Na2CO3, Na2SO4, NaNO3. It was found that the optimal concentration of catalyst is 2.0 g L-1. A pseudo first-order kinetic model was illustrated using the Langmuir-Hinshelwood mechanism, and the adsorption equilibrium constant and the rate constant of the surface reaction were calculated (KBY = 6.126 L mg-1 and kC = 0.272 mg L-1 min-1, respectively. The photodegradation rate was higher in weak acidic than in high acidic and alkaline conditions. The presence of CO32- ions increases the photodegradation rate while Cl-, SO42- and NO3-ions decreases the reaction rate. The rate of photodegradation of BY28 was measured using UV-Vis spectroscopy.

    Full Text Available Plasma treatment is based on the physico-chemical changes of the material surface and as an ecologically and economically acceptable process it can be an attractive alternative to conventional modifications. The possibilities of plasma technology application to the modification of polymer and textile materials are discussed. Different specific properties of the material can be achieved by plasma cleaning, etching, functionalization or polymerization. The final effects are strongly influenced by the treatment parameters (treatment time, pressure, power, gas flow, the applied gas and nature of the material. The plasma treatment of polymers is predominantly focused on cleaning and activation of the surfaces to increase adhesion, binding, wettability, dye ability and printability. Current studies deal more with plasma polymerization where an ultra thin film of plasma polymer is deposited on the material surface and, depending on the applied monomer, different specific properties can be obtained (i.e. chemical and thermal resistance, abrasion resistance, antireflexion, water repellence, etc.. Plasma application to textiles is mostly oriented toward wool and synthetic fibres, though some studies also consider cotton, hemp, flax and silk. The main goal of plasma treatment is to impart a more hydrophilic fibre surface and accordingly increase wettability, dye ability, printability and particularly, shrink resistance in the case of wool. Recent studies have favored technical textiles, where plasma polymerization can offer a wide range of opportunities.

    Textile manufacturing processes offer potential cost and weight advantages over traditional composite materials and processes for transport fuselage elements. In the current study, design cost modeling relationships between textile processes and element design details were developed. Such relationships are expected to help future aircraft designers to make timely decisions on the effect of design details and overall configurations on textile fabrication costs. The fundamental advantage of a design cost model is to insure that the element design is cost effective for the intended process. Trade studies on the effects of processing parameters also help to optimize the manufacturing steps for a particular structural element. Two methods of analyzing design detail/process cost relationships developed for the design cost model were pursued in the current study. The first makes use of existing databases and alternative cost modeling methods (e.g. detailed estimating). The second compares design cost model predictions with data collected during the fabrication of seven foot circumferential frames for ATCAS crown test panels. The process used in this case involves 2D dry braiding and resin transfer molding of curved 'J' cross section frame members having design details characteristic of the baseline ATCAS crown design.

    Despite current legislation and efforts made to improve urban air quality, significant negative effects still persist. That is the case of traffic, which impact on air pollution is a growing problem. For this reason, depollution measures are necessary to reach safer air quality levels. Recently, the use of titanium dioxide (TiO2) based photocatalytic self-cleaning and de-polluting materials has been considered to remove air pollutants, especially NOx. TiO2 can be found in the market under different formats for environmental purposes, and its effectiveness depends not only on the support (concrete, paints, etc) but also on the impregnation method (layer, embedded, etc). By combining laboratory and field campaigns, the LIFE PHOTOCITYTEX project was conceived to demonstrate the effectiveness of using TiO2-based photocatalytic nanomaterials in textiles as a way of alleviating the air pollution in urban areas. Within the project, which is already within its last year, two one-year extensive passive dosimetric campaigns have already been completed to assess their impact on the selected urban sites, measuring before and after the installation of the photocatalytic textile prototypes, respectively. Also, intensive active measurement campaigns (using active dosimetry, monitors and instrumentation for physical parameters) have been conducted to account for winter and summer conditions. Besides, lab-tests have been concluded to determine optimal photocatalytic formulations on textiles, and these have been tested at the EUPHORE simulation chambers under typical environmental conditions of various European cities. Besides the effect on NOx, which has been the main focus of the study, VOCs formation and abatement has been assessed, yielding in a better overall understanding of the whole process and its implications. Very promising results on the deep reduction of NOx have been observed at EUPHORE. From the calculation of the uptake coefficient, a mathematical model tool foresees

    Full Text Available The subject of uncertainty of spectrophotometric measurement of printed textile materials is one of the majorunsolved technical problems in textile colourimetry today. Textile manufacturers are often trying to maintain colourdifference tolerances which are within the range or even less than the uncertainty of the measurement systemcontrolling them. In this paper, two commercial spectrophotometers with different measuring geometries (GretagMacbethEye-One Pro with 450/0° geometry and ChinSpec HP200 with d/8° geometry were comparativelyinvestigated in terms of measurement uncertainty in colour characterization of textile products. Results of the studyindicate that, the despite of different measuring geometry, instruments had the similar measurement repeatabilitybehaviour (repeatability of readings from different parts of the same sample in the case of used digitally printedpolyester materials. The important influence on measurement variability had the material preparation method (werethe materials triple folded, placed on a black backing or a white backing. On the other hand, instruments showeddifference concerning the inter-model agreement. Although this difference was not confirmed as significant withvisual assessment, observers evaluated the measurement readings from the Eye-One Pro spectrophotometer as moreaccurate colour appearance characterization of textile materials.

  1. Electrochemical Techniques in Textile Processes and Wastewater Treatment

    2012-01-01

    Full Text Available The textile industry uses the electrochemical techniques both in textile processes (such as manufacturing fibers, dyeing processes, and decolorizing fabrics and in wastewaters treatments (color removal. Electrochemical reduction reactions are mostly used in sulfur and vat dyeing, but in some cases, they are applied to effluents discoloration. However, the main applications of electrochemical treatments in the textile sector are based on oxidation reactions. Most of electrochemical oxidation processes involve indirect reactions which imply the generation of hypochlorite or hydroxyl radical in situ. These electrogenerated species are able to bleach indigo-dyed denim fabrics and to degrade dyes in wastewater in order to achieve the effluent color removal. The aim of this paper is to review the electrochemical techniques applied to textile industry. In particular, they are an efficient method to remove color of textile effluents. The reuse of the discolored effluent is possible, which implies an important saving of salt and water (i.e., by means of the “UVEC Cell”.

    Paździor, Katarzyna; Klepacz-Smółka, Anna; Wrębiak, Julita; Liwarska-Bizukojć, Ewa; Ledakowicz, Stanisław

    Following new trends we applied oxygen uptake rate (OUR) tests as well as long-term tests (in two batch bioreactors systems) in order to assess the biodegradability of textile wastewater. Effluents coming from a dyeing factory were divided into two streams which differed in inorganic and organic contaminants loads. Usefulness of the stream division was proved. Biodegradation of the low-loaded stream led to over 97% reduction of biochemical oxygen demand (BOD5) together with 80% reduction of chemical oxygen demand (COD) and total organic carbon (TOC). Most of the controlled parameter values were below the levels allowed by legislation for influents to surface water, whereas the high-loaded stream was so contaminated with recalcitrant organic compounds that despite the reduction of BOD5 by over 95%, COD, TOC, total nitrogen and total phosphorus levels exceeded permissible values. OUR tests were aimed at determination of the following kinetic parameters: maximum specific growth rate (μMax), half-saturation constant, hydrolysis constant and decay coefficient for activated sludge biomass for both types of textile wastewater studied. The values of kinetic parameters will be applied in activated sludge models used for prediction and optimisation of biological treatment of textile wastewater.

    Full Text Available The article presents solution for the task of evaluating exergy of the substance in the flow for textile and woven fabrics based on thermodynamic analysis of the corresponding technical systems. The exergy method allows estimating the energy effectiveness for the most problematic heat-technological systems of substance transformation and thus outlining the ways for decreasing the electric-power component in the production prime cost. The actuality of the issue stems from the renowned scenario alteration on the world energy market and is aggravated by necessity of retaining and building up the export potential of the light industry as an important component of the republic national-economic complex. The exergy method has been here for quite a long time and saw the interest fading and appearing again with periodicity of the research-generations alternation. Cooling down of every new generation towards the specified method is explained mostly by unresolved problem of the exergy evaluation for diverse materials, which poses a problem in the course of analysis of the substance transformation systems. The specified problem as a general rule does not create obstacles for energyconversion systems. However, the situation with substance-transformation systems is by far more complicated primarily due to diversity of the materials and respectively of the specification peculiarities of such component of the substance exergy in the flow as chemical component. Abeyance of conclusion in finding the chemical component of the substance exergy does not allow performing thermodynamic valuation of the energy provision for the heat-technological process in full measure. Which complicates the matters of decision-making and finding a medium for reduction of their energy consumption. All stated above relates to the textile industry and in the first instance to the finishing production departments.The authors present the exergy-evaluation problem solution for the

    2008-09-01

    Full Text Available In this paper, a comparative study of the treatment of raw and biotreated (upflow anaerobic sludge blanket, UASB textile dye bath effluent using advanced oxidation processes (AOPs is presented. The AOPs applied on raw and biotreated textile dye bath effluent, after characterization in terms of COD, colour, BOD and pH, were ozone, UV, UV/H2O2 and photo-Fenton. The decolorization of raw dye bath effluent was 58% in the case of ozonation. However it was 98% in the case of biotreated dye bath effluent when exposed to UV/H2O2. It is, therefore, suggested that a combination of biotreatment and AOPs be adopted to decolorize dye bath effluent in order to make the process more viable and effective. Biodegradability was also improved by applying AOPs after biotreatment of dye bath effluent.

  1. An Ontological Solution to Support Interoperability in the Textile Industry

    Science.gov (United States)

    Duque, Arantxa; Campos, Cristina; Jiménez-Ruiz, Ernesto; Chalmeta, Ricardo

    Significant developments in information and communication technologies and challenging market conditions have forced enterprises to adapt their way of doing business. In this context, providing mechanisms to guarantee interoperability among heterogeneous organisations has become a critical issue. Even though prolific research has already been conducted in the area of enterprise interoperability, we have found that enterprises still struggle to introduce fully interoperable solutions, especially, in terms of the development and application of ontologies. Thus, the aim of this paper is to introduce basic ontology concepts in a simple manner and to explain the advantages of the use of ontologies to improve interoperability. We will also present a case study showing the implementation of an application ontology for an enterprise in the textile/clothing sector.

  2. Investigation of a Switchable Textile Communication System on the Human Body

    2014-08-01

    Full Text Available In this paper, a switchable textile communication system working at 2.45 GHz ISM band is presented and studied for different locations within a realistic on-body environment. A 3D laser scanner is used to generate a numerical phantom of the measured subject to improve the accuracy of the simulations which are carried out for different body postures. For the off-body communications, the system is acting as an aperture coupled microstrip patch antenna with a boresight gain of 1.48 dBi. On-body communication is achieved by using a textile stripline, which gives approximately 5 dB transmission loss over 600 mm distance. The system is switched between on and off-body modes by PIN diodes. Common issues, such as shape distortion and body detuning effects which the textile antenna may experience in realistic use are fully discussed. Robust antenna performance is noted in the on-body tests, and an additional 3 dB transmission coefficient deduction was noticed in the most severe shape distortion case.

    Microplastic fibers (MP) from textile weathering and washing are increasingly being recognized as environmental pollutants. The majority of studies on the bioavailability and effects of microplastic focused on small polystyrene spherical plastic particles, while less data are available for fibers and for other materials besides polystyrene. We investigated the ingestion and effects of ground polyethylene terephthalate (PET) textile microfibers (length range: 62-1400 μm, width 31-528 μm, thickness 1-21.5 μm) on the freshwater zooplankton crustacean Daphnia magna after a 48 h exposure and subsequent 24 h of recovery in MP free medium and algae. The majority of ingested fibers by D. magna were around 300 μm, but also some very large twisted MP fibers around 1400 μm were found inside the gut. Exposure to these fibers results in increased mortality of daphnids after 48 h only in the case where daphnids were not pre-fed with algae prior to experiment, but no effect was found when daphnids were fed before the experiments. Regardless of the feeding regime, daphnids were not able to recover from MP exposure after additional 24 h incubation period in a MP free medium with algae. The uptake and effects of PET textile MP on D. magna are presented here for the first time.

    2013-05-01

    The aim of this study is to characterize the waste from the textile industry, to identify the sources and types of waste generation and to find out the economic and employment potential in this sector. Textile waste, its management, and the economic and employment potential in this sector are unrevealed facts in developing countries such as Pakistan. The textile industry is ranked first in export earning in Pakistan. Textile export of yarn and cloth from Faisalabad is US$3 billion per year. On average 161 325 people are employed in the textile sector in Faisalabad, of which 11 860 are involved in solid waste handling and management. The textile industries generate solid wastes such as fibre, metal, plastic and paper waste. A total of 794 209 kg day(-1) (289 886 285 kg year(-1)) solid waste is produced from this sector and purchased by cotton waste junkshop owners at US$125 027 day(-1) (US$45 634 855 year(-1)). Only pre-consumer textile waste is considered. Interestingly no waste is sent to landfill. The waste is first segregated into different categories/ types by hand and then weighed. Cotton waste is sold to brick kilns where it is used as an alternative fuel as it is cheaper than wood/coal. Iron scrap is sold in the junk market from where it is resold to recycling industries. Paper waste is recycled, minimizing the virgin material used for producing new paper products. Iron and plastic drums are returned to the chemical industries for refilling, thus decreasing the cost of dyes and decreasing the demand for new drums. Cutting rags are used for making different things such as ropes and underlay, it is also shredded and used as fillings for pillows and mattresses, thus improving waste management, reducing cost and minimizing the need for virgin material. As no system of quality control and no monitoring of subsequent products exist there is a need to carry out quality control and monitoring.

  6. Experimental Investigation of Textile Composite Materials Using Moire Interferometry

    Ifju, Peter G.

    1995-01-01

    The viability as an efficient aircraft material of advanced textile composites is currently being addressed in the NASA Advanced Composites Technology (ACT) Program. One of the expected milestones of the program is to develop standard test methods for these complex material systems. Current test methods for laminated composites may not be optimum for textile composites, since the architecture of the textile induces nonuniform deformation characteristics on the scale of the smallest repeating unit of the architecture. The smallest repeating unit, also called the unit cell, is often larger than the strain gages used for testing of tape composites. As a result, extending laminated composite test practices to textiles can often lead to pronounced scatter in material property measurements. It has been speculated that the fiber architectures produce significant surface strain nonuniformities, however, the magnitudes were not well understood. Moire interferometry, characterized by full-field information, high displacement sensitivity, and high spatial resolution, is well suited to document the surface strain on textile composites. Studies at the NASA Langley Research Center on a variety of textile architectures including 2-D braids and 3-D weaves, has evidenced the merits of using moire interferometry to guide in test method development for textile composites. Moire was used to support tensile testing by validating instrumentation practices and documenting damage mechanisms. It was used to validate shear test methods by mapping the full-field deformation of shear specimens. Moire was used to validate open hole tension experiments to determine the strain concentration and compare then to numeric predictions. It was used for through-the-thickness tensile strength test method development, to verify capabilities for testing of both 2-D and 3-D material systems. For all of these examples, moire interferometry provided vision so that test methods could be developed with less

    Marshall, David B.; Cox, Brian N.

    2008-08-01

    A new paradigm for ceramic composite structural components enables functionality in heat exchange, transpiration, detailed shape, and thermal strain management that significantly exceeds the prior art. The paradigm is based on the use of three-dimensional fiber reinforcement that is tailored to the specific shape, stress, and thermal requirements of a structural application and therefore generally requires innovative textile methods for each realization. Key features include the attainment of thin skins (less than 1 mm) that are nevertheless structurally robust, transpiration holes formed without cutting fibers, double curvature, compliant integral attachment to other structures that avoids thermal stress buildup, and microcomposite ceramic matrices that minimize spalling and allow the formation of smooth surfaces. All these features can be combined into structures of very varied gross shape and function, using a wide range of materials such as all-oxide systems and SiC and carbon fibers in SiC matrices. Illustrations are drawn from rocket nozzles, thermal protection systems, and gas turbine engines. The new design challenges that arise for such material/structure systems are being met by specialized computational modeling that departs significantly in the representation of materials behavior from that used in conventional finite element methods.

  16. Physiological comfort of biofunctional textiles.

    2006-01-01

    Statistics show that the wear comfort is the most important property of clothing demanded by users and consumers. Hence, biofunctional textiles only have a high market potential, if they are comfortable. In this work it is shown how the thermophysiological and skin sensorial wear comfort of biofunctional textiles can be measured effectively by means of the Skin Model and skin sensorial test apparatus. From these measurements, wear comfort votes can be predicted, assessing a textile's wear comfort in practice. These wear comfort votes match exactly the subjective perceptions of test persons. As a result validated by wearer trials with human test subjects, biofunctional textiles can offer the same good wear comfort as classical, non-biofunctional materials. On the other hand, some of the biofunctional treatments lead to a perceivably poorer wear comfort. In particular, the skin sensorial comfort is negatively affected by hydrophobic, smooth (flat) surfaces that easily cling to sweat-wetted skin, or which tend to make textiles stiffer. As guidelines for the improvement of the thermophysiological or skin sensorial wear comfort, it is recommended to use hydrophilic treatments in a suitable concentration and spun yarns instead of filaments.

    Concerning micro-organisms such as bacteria, viruses and fungi, there is a huge progress in the development of textile materials and procedures which should effectively protect against these various pathogens. In this sense there is especially problematic hospital environment, where it is necessary to take into account properly designed textile material which, when good selected and composed, act as a good barrier against transfer of micro-organisms through material mainly in its wet state. Respect to this it is necessary to be familiar with the rules regarding selection of the input material, the choice of proper yarn construction, the choice of the proper weaving mode, the rules regarding selection of antimicrobial-active compound suitable for (eco-friendly) treatment, and the choice of the most appropriate test method by which it is possible objectively to conclude on the reduction of selected microorganism. As is well known, fabrics are three-dimensional structures with void and non-void areas. Therefore, the physical-chemical properties of the textile material/fabric, the surface characteristics together with the shape of microorganism, and the carriers' characteristics contribute to control the transfer of microorganism through textile material. Therefore, careful planning of textile materials and treatment procedure with the compound which is able to reduce micro-organism satisfactory is particularly important, especially due to the fact that in hospital environment population with impaired immune system is mainly presented.

    2005-02-15

    The adsorption of some textile dyes by diatomite was investigated using Sif Blau BRF (SB), Everzol Brill Red 3BS (EBR), and Int Yellow 5GF (IY). Adsorption of these textile dyes onto diatomite earth samples was studied by batch adsorption techniques at 30 degrees C. The adsorption behavior of textile dyes on diatomite samples was investigated using a UV-vis spectrophotometric technique. The effect of particle size of diatomite, diatomite concentration, the effect of initial dye concentrations, and shaking time on adsorption was investigated. Adsorption coverage over the surface of diatomite was studied using two well-known isotherm models: Langmuir's and Freundlich's. These results suggest that the dye uptake process mediated by diatomite has a potential for large-scale treatment of textile mill discharges. According to the equilibrium studies, the selectivity sequence can be given as IY > SB > EBR. Values of the removal efficiency of the dyes ranged from 28.60 to 99.23%. These results show that natural diatomite holds great potential to remove textile dyes from wastewater.

    2001-08-01

    This article was written to update information on test methods and standards for determining the UV protection of apparel textiles and on factors affecting UV protective properties of fabrics, from dermatological and textile technological viewpoints. Articles from dermatological and textile technological journals published from 1990 to 2001 were identified from MEDLINE, Excerpta Medica/EMBASE, World Textiles, and Textile Technology Digest. Peer-reviewed dermatological articles, textile technological research articles, and normative publications were selected. Independent data extraction was performed by several observers. Spectrophotometry is the preferred method for determining UV protection factor of textile materials. Various textile qualities affect the UV protection factor of a finished garment; important elements are the fabric porosity, type, color, weight, and thickness. The application of UV absorbers in the yarns significantly improves the UV protection factor of a garment. With wear and use, several factors can alter the UV protective properties of a textile, including stretch, wetness, and degradation due to laundering. Standards in the field exist in Australia and Great Britain, and organizations such as the European Standardization Commission in Europe and the American Association of Textile Chemists and Colorists and the American Society for Testing and Materials in the United States are also establishing standards for the determination and labeling of sun protective clothing. Various textile qualities and conditions of wear and use affect UV protective properties of apparel textiles. The use of UV blocking fabrics can provide excellent protection against the hazards of sunlight; this is especially true for garments manufactured as UV protective clothing.

  14. Plasma treatment advantages for textiles

    CERN Document Server

    Sparavigna, Amelia

    2008-01-01

    The textile industry is searching for innovative production techniques to improve the product quality, as well as society requires new finishing techniques working in environmental respect. Plasma surface treatments show distinct advantages, because they are able to modify the surface properties of inert materials, sometimes with environment friendly devices. For fabrics, cold plasma treatments require the development of reliable and large systems. Such systems are now existing and the use of plasma physics in industrial problems is rapidly increasing. On textile surfaces, three main effects can be obtained depending on the treatment conditions: the cleaning effect, the increase of microroughness (anti-pilling finishing of wool) and the production of radicals to obtain hydrophilic surfaces. Plasma polymerisation, that is the deposition of solid polymeric materials with desired properties on textile substrates, is under development. The advantage of such plasma treatments is that the modification turns out to ...

    Everyone in science should have ethics education training. I have seen graduate students taken advantage of by their mentors. Many of us have seen misconduct...but what should we do about it? Young scientists are often unaware of the rules in science and make mistakes because of their ignorance of the rules in that particular field of study. Then there are an increasing number of cases in the news of overt cases of misrepresentation in science. All are welcome to attend this discussion of case studies. A case study on topics such as: how to treat data properly, how our values in science affect our work, who gets authorship on scientific papers, who is first author on a paper, what you should do if you uncover misconduct or plagiarism in your university, and we will discuss the scientist's role in society. This will be a painless, non-confrontational small group, then large group discussion of each case

    Nowadays production systems of fancy yarns for knits allow the creation of extremely complex products in which many effects are obtained by means of color alteration. Current production technique consists in defining type and quantity of fibers by making preliminary samples. This samples are then compared with a reference one. This comparison is based on operator experience. Many samples are required in order to achieve a sample similar to the reference one. This work requires time and then additional costs for a textile manufacturer. In addition, the methodology is subjective. Nowadays, spectrophotometers are the only devices that seem to be able to provide objective indications. They are based on a spectral analysis of the light reflected by the knit material. In this paper the study of a new method for color evaluation of a mix of wool fibers with different colors is presented. First of all fiber characterization were carried out through scattering and absorption coefficients using the Kubelka-Munk theory. Then the estimated color was compared with a reference item, in order to define conformity by means of objective parameters. Finally, theoretical characterization was compared with the measured quantity. This allowed estimation of prediction quality.

    The aim of this research was to study a system of acquisition and processing of images capable of confronting colored wool with a reference specimen, in order to define the conformity using objective parameters. The first step of the research was to comprise and to analyze in depth the problem: there has been numerous implications of technical, physical, cultural, biological and also psychological character, that come down from the attempt of giving a quantitative appraisal to the color. In the scene of the national and international scientific and technological research, little has been made as regards measurement of color through digital processing of the images through linear CCD. The reason is fundamentally of technological nature: only during the last years we found the presence on the market of low cost equipment capable of acquiring and processing images with adequate performances and qualities. The job described has permitted to create a first prototype of system for the color measuring with use of CCD linear devices. -Hardware identification to carry out a series of tests and experiments in laboratory. -Verification of such device in a textile facility. -Statistics analysis of the collected data and of the employed models.

    Natural ageing process occurs throughout the life cycle of textile products, which may possess influences on the release behavior of additives such as silver nanoparticles (Ag NPs). In this study, we assessed the releasability of Ag NPs from a Ag NPs functionalized textile in five different exposure scenarios (i.e. tap water (TW), pond water (PW), rain water (RW), artificial sweat (AS), and detergent solution (DS) along with deionized water (DW) as reference), which were very likely to occur throughout the life cycle of the textile. For the pristine textile, although the most remarkable release was found in DW (6–15 μg Ag/g textile), the highest release rate was found in RW (around 7 μg Ag/(g textile·h)). After ageing treatment, the total released Ag could be increased by 75.7~386.0% in DW, AS and DS. Morphological analysis clearly showed that the Ag NPs were isolated from the surface of the textile fibre due to the ageing treatment. This study provides useful information for risk assessment of nano-enhanced textile products.

    2009-03-01

    Full Text Available The mechanical behavior of polymer concrete reinforced with textile trimming waste was investigated. Two series of polymer concrete formulations were studied, with different resin/sand (i.e. binder/fine aggregate weight ratios. In each series, recycled textile chopped fibers at 1 and 2% of the total weight was used. Flexural and compressive tests were performed at room temperature and load vs. displacement curves were plotted up to failure. In the study, both the influence of fiber content and resin/sand weight ratio were considered relative to the behavior of polymer concrete reinforced with textile fibers. A decrease in properties was observed as function of textile fibers content. When specific properties were considered, this tendency was kept. However, higher textile fibers content lead to a smoother failure, unlike brittleness failure behavior of unreinforced polymer concrete.

    Full Text Available The present work aim was to study two composite textile pieces from Santarém Diocesan Museum, including their historic context, their conservation condition and the characterization of their constituent parts, which established the date of production. Both pieces belonged to the First Bishop of Daman (1840-1900 and were selected for their historic interest and originality, and for representing a case study in terms of materials, techniques and decoration. They are also a good example of the conservation problems that can occur in liturgical textiles. The diagnosis was extended using optical microscopy, Fourier transform infrared spectroscopy, energy dispersive X-ray fluorescence and Raman spectroscopy. These techniques allowed the identification of the fibres, binder, metals and pigments, confirming that the pieces date back to the late nineteenth century. Among the main forms of degradation, it was observed: structural deformations, dirt and material losses, not only in areas with fabric but also with metallic embroidery and painted layers.

    Size exclusion chromatography (SEC), especially coupled with multiple angle laser light scattering detector (MALLS) is a powerful tool in diagnostics of deterioration of historic and art objects to evaluate their condition. In this paper, SEC-UV-MALLS-DRI technique was applied to study degradation of silk fibroin samples ( Bombyx mori) artificially aged under various conditions: in the presence of oxygen, in different amount of water vapour and in volatile organic products (VOCs), all at temperature of 90 °C. Conditions were chosen in such a way that it mimicked real conditions of textiles' storing during exhibitions and in show cases. The influence of temperature, moisture and VOCs content on the state of silk textiles was examined with the use of size exclusion chromatography. Pseudo-zero-order Ekenstam equation was applied to study degradation rates of fibroin with use of the approximated values of DP of fibroin.

    2015-07-01

    Full Text Available Textile electrodes are becoming an attractive means in the facilitation of surface electrical stimulation. However, the stimulation comfort of textile electrodes and the mechanism behind stimulation discomfort is still unknown. In this study, a textile stimulation electrode was developed using conductive fabrics and then its impedance spectroscopy, stimulation thresholds, and stimulation comfort were quantitatively assessed and compared with those of a wet textile electrode and a hydrogel electrode on healthy subjects. The equivalent circuit models and the finite element models of different types of electrode were built based on the measured impedance data of the electrodes to reveal the possible mechanism of electrical stimulation pain. Our results showed that the wet textile electrode could achieve similar stimulation performance as the hydrogel electrode in motor threshold and stimulation comfort. However, the dry textile electrode was found to have very low pain threshold and induced obvious cutaneous painful sensations during stimulation, in comparison to the wet and hydrogel electrodes. Indeed, the finite element modeling results showed that the activation function along the z direction at the depth of dermis epidermis junction of the dry textile electrode was significantly larger than that of the wet and hydrogel electrodes, thus resulting in stronger activation of pain sensing fibers. Future work will be done to make textile electrodes have similar stimulation performance and comfort as hydrogel electrodes.

    In this paper, we conduct a feasibility study to investigate the future potential of textile composites with shape memory alloys. Two different types of SMA-based textile composites are presented. First, a composite plate with embedded woven SMA layer is fabricated, and the stiffness tuning capability is evaluated by impact vibration tests. The results are not favorable, but may be improved by increasing the volume fraction of SMA, and by controlling the prestrain more accurately during the lamination process. The modeling and analysis methodology for woven SMA-based composites are briefly discussed. Then, the possibility of textile composites with SMA stitching is discussed, that is expected to give the composites multi-functions such as tunable stiffness, shape control and sensing capability, selectively distributed on demand.

    2013-01-01

    Here we discuss two alternative approaches for building flexible batteries for applications in smart textiles. The first approach uses well-studied inorganic electrochemistry (Al-NaOCl galvanic cell) and innovative packaging in order to produce batteries in a slender and flexible fiber form that can be further weaved directly into the textiles. During fabrication process the battery electrodes are co-drawn within a microstructured polymer fiber, which is later filled with liquid electrolyte. The second approach describes Li-ion chemistry within solid polymer electrolytes that are used to build a fully solid and soft rechargeable battery that can be furthermore stitched onto a textile, or integrated as stripes during weaving process.

    The combination of textile fabrics with microelectronics will lead to completely new applications, thus achieving elements of ambient intelligence. The integration of sensor or actuator networks, using fabrics with conductive fibres as a textile motherboard enable the fabrication of large active areas. In this paper we describe an integration technology for the fabrication of a "smart textile" based on a wired peer-to-peer network of microcontrollers with integrated sensors or actuators. A self-organizing and fault-tolerant architecture is accomplished which detects the physical shape of the network. Routing paths are formed for data transmission, automatically circumventing defective or missing areas. The network architecture allows the smart textiles to be produced by reel-to-reel processes, cut into arbitrary shapes subsequently and implemented in systems at low installation costs. The possible applications are manifold, ranging from alarm systems to intelligent guidance systems, passenger recognition in car seats, air conditioning control in interior lining and smart wallpaper with software-defined light switches.

    Beer, M.; Schrank, V.; Gloy, Y.-S.; Gries, T.

    2016-07-01

    Technical textiles are used in various fields of applications, ranging from small scale (e.g. medical applications) to large scale products (e.g. aerospace applications). The development of new products is often complex and time consuming, due to multiple interacting parameters. These interacting parameters are production process related and also a result of the textile structure and used material. A huge number of iteration steps are necessary to adjust the process parameter to finalize the new fabric structure. A design method is developed to support the systematic development of technical textiles and to reduce iteration steps. The design method is subdivided into six steps, starting from the identification of the requirements. The fabric characteristics vary depending on the field of application. If possible, benchmarks are tested. A suitable fabric production technology needs to be selected. The aim of the method is to support a development team within the technology selection without restricting the textile developer. After a suitable technology is selected, the transformation and correlation between input and output parameters follows. This generates the information for the production of the structure. Afterwards, the first prototype can be produced and tested. The resulting characteristics are compared with the initial product requirements.

    Concepts of technical fibers following models for the polar bear hair to be used for textile solar collectors are discussed. The approach to coat fibers with a thin layer into which fluorescent dyestuff was dispersed was studied experimentally. Modified fibers made of different polymers were characterized with respect to optical properties relevant for the bionic model. In the case of poly(methylmethacrylate) fibers, the envisaged effect could be achieved to high efficiency. The optical performance could be enhanced by ultrasonic dispersion of the dyestuff in the coating matrix. The effect is less significant in semi-crystalline fibers such as poly(ethylene terephthalate), which is attributed to diffuse scattering. (author)

    2007-07-01

    Linen is the most historical Egyptian textile fibre liable to fungal deterioration. Fungal deterioration of dyed linen textiles may appear as undesirable different stains. In order to success in removing of fungal stains from biodeteriorated historical Egyptian dyed linen textiles, it is necessary to understand the nature and causes of these stains, hence their subsequent removal. So this paper aims to investigate the effect of fungi on dyed linen textiles. In this study linen textile samples were experimentally dyed by two different dyes, blue one as an example to vat dye and yellow one as an example to direct dye. This work is done on two of the most important dyes (Turmeric and indigo), which were popular in most of historical periods in Egypt. Dyed linen samples were experimentally biodegraded by thirty different fungal strains isolated previously from historical Egyptian linen samples. The produced change in colours of the biodeteriorated samples was detected visually. Also, the change in reflection spectra and colour differences produced to dyed linen textiles after fungal deterioration, were assessed and evaluated by using spectrophotometer. This study reported that most of tested fungi contribute to discoloration of all tested dyed linen samples. These results indicate that most of stains on historical Egyptian dyed linen textiles, may be fungal stains. The results confirm that undyed linen textiles more liable to fungal biodeterioration than dyed ones. Also the results show that yellow dyed linen textiles are more susceptible to fungal deterioration than blue dyed linen textiles. The obtained results show that Alternaria tenuissima, Chaetomium globosum, Chaetomium sp., Penicillium raistrickii, P. soppi, P. asperum, P. citrinum, Aspergillus carbonarius, A. fischeri, A. nidulans, A. terreus and A. niger, had showed the maximum colour changes of the deteriorated yellow dyed linen samples. The results also show that Alternaria tenuissima, Chaetomium sp

    Fimbristylis dichotoma, Ammannia baccifera and their co-plantation consortium FA independently degraded Methyl Orange, simulated dye mixture and real textile effluent. Wild plants of F. dichotoma and A. baccifera with equal biomass showed 91% and 89% decolorization of Methyl Orange within 60h at a concentration of 50ppm, while 95% dye removal was achieved by consortium FA within 48h. Floating phyto-beds with co-plantation (F. dichotoma and A. baccifera) for the treatment of real textile effluent in a constructed wetland was observed to be more efficient and achieved 79%, 72%, 77%, 66% and 56% reductions in ADMI color value, COD, BOD, TDS and TSS of textile effluent, respectively. HPTLC, GC-MS, FTIR, UV-vis spectroscopy and activated oxido-reductive enzyme activities confirmed the phytotrasformation of parent dye in to new metabolites. T-RFLP analysis of rhizospheric bacteria of F. dichotoma, A. baccifera and consortium FA revealed the presence of 88, 98 and 223 genera which could have been involved in dye removal. Toxicity evaluation of products formed after phytotransformation of Methyl Orange by consortium FA on bivalves Lamellidens marginalis revealed less damage of the gills architecture when analyzed histologically. Toxicity measurement by Random Amplification of Polymorphic DNA (RAPD) technique revealed bivalve DNA banding pattern in treated Methyl Orange sample suggesting less toxic nature of phytotransformed dye products.

    Silver, both in the nano as well as in other forms, is used in many applications including antimicrobial textiles. Washing of such textiles has already been identified as an important process that results in the release of silver into wastewater. This study thus investigated the release of silver from eight different commercially available silver-textiles during a washing and rinsing cycle. The silver released was size-fractionated and characterized using electron microscopy. In addition, the antimicrobial functionality of the textiles was tested before and after washing. Three of the textiles contained nanosized silver (labeled or confirmed by manufacturers' information), another used a metallic silver wire and four contained silver in undeclared form. The initial silver content of the textiles was between 1.5 and 2925mg Ag/kg. Only four of the investigated textiles leached detectable amounts of silver, of which 34-80% was in the form of particles larger than 450nm. Microscopic analysis of the particles released in the washing solutions identified Ti/Si-AgCl nanocomposites, AgCl nanoparticles, large AgCl particles, nanosilver sulfide and metallic nano-Ag, respectively. The nanoparticles were mainly found in highly agglomerated form. The identified nanotextiles showed the highest antimicrobial activity, whereas some of the other textiles, e.g. the one with a silver wire and the one with the lowest silver content, did not reduce the growth of bacteria at all. The results show that different silver textiles release different forms of silver during washing and that among the textiles investigated AgCl was the most frequently observed chemical form in the washwater.

    2010-09-15

    This study investigated the biosorption of Reactive Red 195 (RR 195), an azo dye, from aqueous solution by using cone biomass of Pinus sylvestris Linneo. To this end, pH, initial dye concentration, biomass dosage and contact time were studied in a batch biosorption system. Maximum pH for efficient RR 195 biosorption was found to be 1.0 and the initial RR 195 concentration increased with decreasing percentage removal. Biosorption capacity increased from 6.69 mg/g at 20 deg. C to 7.38 mg/g at 50 deg. C for 200 mg/L dye concentration. Kinetics of the interactions was tested by pseudo-first-order and pseudo-second-order kinetics, the Elovich equation and intraparticle diffusion mechanism. Pseudo-second-order kinetic model provided a better correlation for the experimental data studied in comparison to the pseudo-first-order kinetic model and intraparticle diffusion mechanism. Moreover, the Elovich equation also showed a good fit to the experimental data. Freundlich and Langmuir adsorption isotherms were used for the mathematical description of the biosorption equilibrium data. The activation energy of biosorption (Ea) was found to be 8.904 kJ/mol by using the Arrhenius equation. Using the thermodynamic equilibrium coefficients obtained at different temperatures, the study also evaluated the thermodynamic constants of biosorption ({Delta}G{sup o}, {Delta}H{sup o} and {Delta}S). The results indicate that cone biomass can be used as an effective and low-cost biosorbent to remove reactive dyes from aqueous solution.

    2013-03-01

    The objective of the present work was to develop a plant-bacterial synergistic system for efficient treatment of the textile effluents. Decolorization of the dye Scarlet RR and a dye mixture was studied under in vitro conditions using Glandularia pulchella (Sweet) Tronc., Pseudomonas monteilii ANK and their consortium. Four reactors viz. soil, bacteria, plant and consortium were developed that were subjected for treatment of textile effluents and dye mixture. Under in vitro conditions G. pulchella and P. monteilii showed decolorization of the dye Scarlet RR (SRR) by 97 and 84%, within 72 and 96 h respectively, while their consortium showed 100% decolorization of the dye within 48 h. In case of dye mixture G. pulchella, P. monteilii and consortium-PG showed an ADMI removal of 78, 67 and 92% respectively within 96 h. During decolorization of SRR G. pulchella showed induction in the activities of enzymes lignin peroxidase and DCIP reductase while P. monteilii showed induction of laccase, DCIP reductase and tyrosinase, indicating their involvement in the dye metabolism. High Performance Liquid Chromatography (HPLC), Fourier Transform Infra Red Spectroscopy (FTIR) and High Performance Thin Layer Chromatography (HPTLC) confirmed the biotransformation of SRR and dye mixture into different metabolites. Soil, bacteria, plant and consortium reactors performed an ADMI removal of 42, 46, 62 and 93% in the first decolorization cycle while it showed an average ADMI removal of 21, 27, 59 and 93% in the next three (second, third and fourth) decolorization cycles respectively for the dye mixture within 24 h. Consortium reactor showed an average ADMI removal of 95% within 48 and 60 h for textile effluents A and B respectively for three decolorization cycles, while it showed an average TOC, COD and BOD removal of 74, 70 and 70%, 66, 72 and 67%, and 70, 70 and 66% for three decolorization cycles of the dye mixture (second, third and fourth decolorization cycles), effluent A and

    The present study evaluates an obligatory interaction between the yeast Saccharomyces cerevisiae NCIM 3312 and the bacterium Pseudomonas sp. strain BCH3 for the biodegradation of the dye Rubin 3GP (R3GP). No significant degradation of R3GP was observed either by Saccharomyces cerevisiae NCIM 3312 or by Pseudomonas sp. strain BCH3, when both the cultures were tested individually under their respective optimum medium conditions. However, when both of them were allowed to intermingle with each other, R3GP was found to be degraded within 72 h, with a steady increase in β -1,3-glucanase, chitinase and protease activity in the culture supernatant; indicating the possible role of Pseudomonas sp. strain BCH3 in cell wall lysis of S. cerevisiae NCIM 3312. The present study elucidates a rare microbial interaction where the bacterium Pseudomonas sp. strain BCH3 utilizes lysed yeast cells as the sole source of nutrients for its own growth and subsequently performs decolorization and degradation of R3GP. Enzymatic status showed involvement of various oxidoreductive enzymes like lignin peroxidase, laccase, DCIP reductase and azo reductase, indicating their role in decolorization and degradation of R3GP. Degradation was confirmed using HPLC, FTIR analysis and the biochemical pathway of degradation was elucidated by using GC-MS analysis.

In addition, information on their health status in general was collected in advance. Contrary to expectation, there was no significant change in respiratory function. However, the musculo-skeletal problems were found to be abundantly present with pain in 91% of the subjects. Region-wise mapping of pain revealed that postural pain in low back was present in 47% while in neck was 19%. Scapular muscles on the right side were involved in stabilizing shoulder, which never went overhead. On the contrary, left shoulder was raised as high (>90 degrees in spinning action, while pulling thread. This muscle work involved trapezius, deltoid and triceps action concentrically in lifting and while coming to starting position slowly, eccentrically. There was no pause since the wheel continued to spin the thread continuously, unless a worker opted to stop the work. Accordingly, left wrist and hand were in holding contraction while the right wrist and hand holding the handle were also in a fixed position with wrist in flexion with supinated forearm. Though the overall job was light as per peak HR, there was pain due to fatigue and grip strength weakened by around 10%, at the end of the day′s work. In conclusion, pain and fatigue were found to be the main problems for women in the spinning section of the small-scale industry under this study. Women have to take up dual responsibility of a full-time job as well as the domestic work. It was considered that ergonomic factors such as provision of a backrest and frequent rest periods could remediate the musculo-skeletal symptoms.

    Since birth the first and the most natural interface for the body is fabric, a soft, warm and reassuring material. Cloth is usually covering more than 80 % of the skin; which leads us to consider textile material as the most appropriate interface where new sensorial and interactive functions can be implemented. The new generation of personalised monitoring systems is based on this paradigm: functions like sensing, transmission and elaboration are implementable in the materials through the textile technology. Functional yarns and fibres are usable to realise garments where electrical and computing properties are combined with the traditional mechanical characteristics, giving rise to textile platforms that are comparable with the cloths that are normally used to produce our garments. The feel of the fabric is the same, but the functionality is augmented. Nowadays, consumers demand user-friendly connectivity and interactivity; sensing clothes are the most natural and ordinary interface able to follow us, everywhere in a non-intrusive way, in natural harmony with our body.

    Textile-structured solar cells are frequently discussed in the literature due to their prospective applications in wearable devices and in building integrated solar cells that utilize their flexibility, mechanical robustness, and aesthetic appearance, but the current approaches for textile-based solar cells-including the preparation of fibre-type solar cells woven into textiles-face several difficulties from high friction and tension during the weaving process. This study proposes a new structural concept and fabrication process for monolithic-structured textile-based dye-sensitized solar cells that are fabricated by a process similar to the cloth-making process, including the preparation of wires and yarns that are woven for use in textiles, printed, dyed, and packaged. The fabricated single-layered textile-based dye-sensitized solar cells successfully act as solar cells in our study, even under bending conditions. By controlling the inter-weft spacing and the number of Ti wires for the photoelectrode conductor, we have found that the performance of this type of dye-sensitized solar cell was notably affected by the spacing between photoelectrodes and counter-electrodes, the exposed areas of Ti wires to photoelectrodes, and photoelectrodes' surface morphology. We believe that this study provides a process and concept for improved textile-based solar cells that can form the basis for further research.

    Denim trousers, commonly known as "blue jeans", have maintained their popularity for many years. For the purpose of supporting customers' purchasing behaviour and to address their aesthetic taste, companies have been trying in recent years to develop various techniques to improve the visual aspects of denim fabrics. These techniques mainly include printing on fabrics, embroidery and washing the final product. Especially, fraying certain areas of the fabric by sanding and stone washing to create designs is a popular technique. However, due to certain inconveniences caused by these procedures and in response to growing demands, research is underway to obtain a similar appearance by creating better quality and more advantageous manufacturing conditions. As is known, the laser is a source of energy which can be directed on desired objects and whose power and intensity can be easily controlled. Use of the laser enables us to cut a great variety of material from metal to fabric. Starting off from this point, we thought it would be possible to transfer certain designs onto the surface of textile material by changing the dye molecules in the fabric and creating alterations in its colour quality values by directing the laser to the material at reduced intensity. This study mainly deals with a machine specially designed for making use of laser beams to transfer pictures, figures as well as graphics of desired variety, size and intensity on all kinds of surfaces in textile manufacturing such as knitted—woven fabrics, leather, etc. at desired precision and without damaging the texture of the material. In the designed system, computer-controlled laser beams are used to change the colour of the dye material on the textile surface by directing the laser beams at a desired wavelength and intensity onto various textile surfaces selected for application. For this purpose, a laser beam source that can reach the initial level of power and that can be controlled by means of a

Wearable, comfortable and smart textiles incorporating sensors are good approaches to solve this problem. In most of the cases, electrical sensors are integrated, showing significant limits such as for the monitoring of anaesthetized patients during Magnetic Resonance Imaging (MRI). OFSETH (Optical Fibre Embedded into technical Textile for Healthcare) uses optical sensor technologies to extend the current capabilities of medical technical textiles.

    Various test methods commonly used for measuring properties of tape laminate composites were evaluated to determine their suitability for the testing of textile composites. Three different types of textile composites were utilized in this investigation: two-dimensional (2-D) triaxial braids, stitched uniweave fabric, and three-dimensional (3-D) interlock woven fabric. Four 2-D braid architectures, five stitched laminates, and six 3-D woven architectures were tested. All preforms used AS4 fibers and were resin-transfer-molded with Shell RSL-1895 epoxy resin. Ten categories of material properties were investigated: tension, open-hole tension, compression, open-hole compression, in-plane shear, filled-hole tension, bolt bearing, interlaminar tension, interlaminar shear, and interlaminar fracture toughness. Different test methods and specimen sizes were considered for each category of test. Strength and stiffness properties obtained with each of these methods are documented in this report for all the material systems mentioned above.
