    Clothing textiles protect our human body against external factors. These textiles are not sterile and can harbor high bacterial counts as sweat and bacteria are transmitted from the skin. We investigated the microbial growth and odor development in cotton and synthetic clothing fabrics. T-shirts were collected from 26 healthy individuals after an intensive bicycle spinning session and incubated for 28 h before analysis. A trained odor panel determined significant differences between polyester versus cotton fabrics for the hedonic value, the intensity, and five qualitative odor characteristics. The polyester T-shirts smelled significantly less pleasant and more intense, compared to the cotton T-shirts. A dissimilar bacterial growth was found in cotton versus synthetic clothing textiles. Micrococci were isolated in almost all synthetic shirts and were detected almost solely on synthetic shirts by means of denaturing gradient gel electrophoresis fingerprinting. A selective enrichment of micrococci in an in vitro growth experiment confirmed the presence of these species on polyester. Staphylococci were abundant on both cotton and synthetic fabrics. Corynebacteria were not enriched on any textile type. This research found that the composition of clothing fibers promotes differential growth of textile microbes and, as such, determines possible malodor generation.

    Full Text Available In this research, thermal and water vapor resistance, components of thermal comfort of 65/35 and 33/67% polyester/ cotton (PES/CO blend fabrics woven with 2/2 twill, matt twill, cellular and diced weaves, which are commonly used for clothing, were determined. The results indicate that both the fabric construction and the constituent fiber properties affect thermal comfort properties of clothing woven fabrics. Cellular weave, which is derivative of sateen weave and diced weave, which is compound weave, has the highest thermal resistance appropriating for cold climatic conditions. On the other hand, the 2/2 twill weave and matt twill weave, which is derivative of sateen weave, depicted the lowest water vapor thermal resistance, making it convenient for hot climatic conditions. Besides, fabrics woven with 65/35% PES/CO blend yarns have higher thermal resistance, so they are suitable for cold climatic conditions. Fabrics woven with 33/67% PES/CO blend yarns have lower water vapor resistance, so they are convenient for hot climatic conditions.

    Full Text Available Waterhyacinth is one of the most dangerous aquatic weeds causing various ecological and environmental issues. The plant has several pharmaceutical properties in spite of its harmful nature. In the present study, perspiration pads and cotton cloth fabricated with the ethyl acetate extract of waterhyacinth were evaluated for its activity against Corynebacterium. Perspiration pads and samples of cotton cloth were fabricated with ethyl acetate extract of Eichhornia crassipes by three methods, namely, dipping, sonication, and homogenization. The antimicrobial activity of the fabricated textile materials was tested against Corynebacterium, a microorganism commonly seen in human sweat. Disc diffusion method (AATCC 147 was used for evaluating the antimicrobial nature of the fabricated samples. Sonication was found to be efficient for coating of the extract on the cotton cloth, whereas dipping method was found to be efficient in case of perspiration pads. No bacterial growth was observed under and on the fabricated cloth and perspiration pads indicating that the fabrics possess bacteriostatic property and not bactericidal property and the absence of leaching of the extract. The results showed significant antimicrobial activity of the ethyl acetate extract of Eichhornia crassipes coated onto fabrics against Corynebacterium with no growth under and on the test sample.

    An alkaliphilic bacterium, Klebsiella sp. strain RJ-03, produced a biosurfactant, which showed low viscosity with pseudoplastic rheological behavior and exhibited emulsification activity with oils and hydrocarbons. The biosurfactant has excellent oil removing efficiency as compared to chemical surfactants. The isolated biosurfactant has compatibility with detergents and enhanced oil removing efficiency from soil and cotton cloths. It comprised of sugar, uronic acid, protein and sulfate. GC-MS analysis confirmed the presence of six monosaccharides (w/w), glucose (6.65%), galactose (23.98%), rhamnose (14.94%), mannose (17.54%), fucose (9.47%) and 6-O-Me-galactose (1.4%). It is a high molecular weight, thermostable biopolymer showing degradation above 300 °C. Positive ion reflector mode of MALDI TOF-TOF MS analysis revealed series of low and mid range mass peaks (m/z) corresponding to mono-, di-, tri- and oligo-saccharides content. The NMR, FT-IR, EDX-SEM, AFM and PSD analysis confirmed the presence of functional groups, bonds, elements and particle size respectively.

    Textiles are a commonly encountered source of evidence in forensic cases. In the past, most research has been focused on how textiles affect the decomposition process while little attention has been paid to how the decomposition products interact with the textiles. While some studies have shown that the presence of remains will have an effect on the degradation of clothing associated with a decaying body, very little work has been carried out on the specific mechanisms that prevent or delay textile degradation when in contact with decomposing remains. In order to investigate the effect of decomposition fluid on textile degradation, three clothed domestic pig (Sus scrofa domesticus) carcasses were placed on a soil surface, textile specimens were collected over a period of a year and were then analysed using ATR-FTIR spectroscopy and GC-MS. Multivariate statistical analysis was used to analyse the data. Cotton specimens not associated with remains degraded markedly, whereas the samples exposed to decomposition fluids remained relatively intact over the same time frame. An investigation of the decomposition by-products found that the protein-related bands remained stable and unchanged throughout the experiment. Lipid components, on the other hand, demonstrated a significant change; this was confirmed with the use of both ATR-FTIR spectroscopy and GC-MS. Through an advanced statistical approach, information about the decomposition by-products and their characteristics was obtained. There is potential that the lipid profile in a textile specimen could be a valuable tool used in the examination of clothing located at a crime scene.

    To study the influence of different irrigation system for drip irrigation under plastic film with saline water on cotton growth and yields, field experiments at key irrigation experiment station of water resources management division in Bayingolin Mongol Autonomous Prefecture, Xinjiang, China were set up consist of different irrigation ratio (5250, 4500, 3750, 3000m3/hm2), different irrigation times (24, 12 and 8 times) and different rotation irrigation modes. The results show that: with the larger irrigation ratio, the cotton growth and yields was also better, and the significant influence on cotton growth and yields for irrigation ratio is between 3750-4500 m3/hm2. When the irrigation ratio is smaller (3000m3/hm2), cotton growth and yields for irrigation times of 8 times are higher, When the irrigation ratio is bigger (4500m3/hm2), cotton growth for irrigation times of 12 times are better and its cotton yields are higher correspondingly. According to the growth of cotton, yields and water productivity, the suitable irrigation system of cotton is the irrigation ratio of 4500-3750 m3/ hm2 and the irrigation times of 18 times for drip irrigation under plastic film with saline water. For different rotation drip irrigation experiments with saline water and fresh water, the cotton yields and irrigation water productivity is higher under the disposal of SF (rotation irrigation in first 6 times with saline water irrigation and then 6 times with fresh water irrigation) compared to FS (rotation irrigation in first 6 times with fresh water and then 6 times with saline water) and SSFA (rotation irrigation with twice saline water and once fresh water) compared to SFA (alternative irrigation with saline water and fresh water). Compared to the different alternate irrigation experiments, the cotton yields and water productivity for pure saline water irrigation is higher. In addition, the trend is the larger the irrigation ratio and the higher the yields. It maybe dues to the low

    Full Text Available The production of extracellular amylase was investigated employing our laboratory isolate, Aspergillus niger sp. MK 07 and effect of process variables on enzyme production, was studied in a fermentor. It was found that amylase production was maximum when the fermentor volume was maintained at 70%, rate of agitation at 250 rpm, air supply at 2.5 vvm, inoculum concentration of 10%, and a pH of 5.0. Highest enzyme production obtained under all optimized conditions was 1734 U/mL with sucrose as carbon substrate and corn steep liquor as nitrogen source. Enzyme purification studies by ammonium sulphate precipitation and Sephadex G-100 chromatography was evaluated for obtaining purified enzyme. Thermostability of amylase were evaluated with varying concentrations from 0.2 to 0.5 M concentrations of calcium chloride and the highest activity obtained was 3115 U/mL with 0.3 M calcium chloride at 55°C. Effect of temperature and pH on the activity of purified enzyme was evaluated and the purified enzyme showed an activity till 75°C and a pH of 6.5. Application potential of partially purified alpha amylase on desizing of cotton cloth was evaluated with varying enzyme concentrations from 50 to 500 U/mL and the highest desizing activity was found to be at 300 U/mL.

    Chemical exposures may be responsible for firefighters' elevated incidences of cancer and cardiovascular disease. This study characterized semivolatile chemical contamination on firefighter personal protective clothing to assess exposure of firefighters to these chemicals. Samples from used firefighter protective clothing, including gloves, hood, and one coat wristlet, were extracted with methylene chloride and analyzed by EPA method 8270 for semivolatile contaminants, including 20 polycyclic aromatic hydrocarbons (PAHs) and 6 phthalate diesters. Twenty-two of the chemicals of interest were found on at least one clothing swatch. Only di-(2-ethylhexyl) phthalate (DEHP), a plasticizer, added to polyvinyl chloride (PVC) to increase flexibility, was found on every swatch. DEHP concentrations were the highest of any chemical measured, and were 52 to 875 times higher than any PAH concentration measured. DEHP was also detected on most items of unused firefighter personal protective clothing, although at much lower levels. These findings suggest that firefighters are exposed to high levels of DEHP, a probable human carcinogen, and at levels much higher than PAHs, the semivolatile toxic combustion products most extensively studied historically. Firefighter exposure to DEHP and other phthalate diesters therefore merits further study.

    2010-01-01

    Effects of soil moisture on cotton root length density (total root length per unit soil volume) and yield under drip irrigation with plastic mulch were studied through field experiments. The results indicate that spatial distributions of root length density of cotton under various water treatments were basically similar. Horizontally, both root length densities of cotton in wide and narrow rows were similar, and higher than that between mulches. Vertically, root length density of cotton decreased with increasing soil depth. The distribution of root length density is different under different irrigation treatments. In conditions of over-irrigation, the root length density of cotton between mulches would increase. However, it would decrease in both the wide rows and narrow rows. The mean root length density of cotton increased with increasing irrigation water. Water stress caused the root length density to increase in lower soil layers. There is a significant correlation between root length density and yields of cotton at the flower-boll and wadding stages. The regression between irrigation amount and yield of cotton can be expressed as y = -0.0026x2+18.015x-24845 (R2 = 0.959). It showed that the irrigation volume of 3,464.4 m3/hm2 led to op-timal root length density. The yield of cotton was 6,360 .8 kg/hm2 under that amount of irrigation.

    In northwestern China, there has been a change from traditional cultivation system (TC) with no mulching and flood irrigation to a more modern cultivation system (MC) using plastic film mulching with drip irrigation. A field study was conducted to compare soil CO2 concentrations and soil surface CO2 fluxes between TC and MC systems during a cotton growing season. CO2 concentrations in the soil profile were higher in the MC system (3 107-9212 μL L-1) than in the TC system (1 275-8994 μL L-1) but the rate of CO2 flux was lower in the MC system. Possible reasons for this included decreased gas diffusion and higher soil moisture due to the mulching cover in the MC system, and the consumption of soil CO2 by weathering reactions. Over the whole cotton growing season,accumulated rates of CO2 flux were 300 and 394 g C m-2 for the MC and TC systems, respectively. When agricultural practices were converted from traditional cultivation to a plastic film mulching system, soil CO2 emissions could be reduced by approximately 100 g C m-2 year-1 in agricultural lands in arid and/or semi-arid areas of northern and northwestern China.

    A field experiment with complete combination design was conducted to study the effects of partitioning alternative drip irrigation with plastic mulch and nitrogen fertilization on the dry matter accumulation and nitrogen use efficiency of cotton plant. Three levels of irrigation (260, 200, and 140 mm) and of nitrogen fertilizer (270, 180, and 90 kg.hm-2) were installed. The cotton dry mass was the highest in treatments medium nitrogen/high water and high nitrogen/high water. As compared with that in high nitrogen/high water treatment, the nitrogen use efficiency for dry matter accumulation in medium nitrogen/high water treatment was increased by 34.0% -44.6%, with an average of 34.7% , while the water use efficiency was decreased by 6.4% -10.7%, averagely 10.2%. As for the nitrogen accumulation in cotton plant, the nitrogen use efficiency was the highest in medium nitrogen/high water treatment, and the water use efficiency was the highest in high nitrogen/medium water treatment. Compared with high nitrogen/high water treatment, medium nitrogen/high water treatment increased the nitrogen use efficiency for cotton nitrogen accumulation by 29.0% -41.7%, but decreased the water use efficiency for cotton nitrogen accumulation by 5.5%-14.0%. Among the treatments of coupling water and nitrogen of higher cotton yield, treatment medium nitrogen/high water had the higher cotton nitrogen recovery rate, nitrogen agronomic efficiency, and apparent use efficiency than the treatments high nitrogen/medium water and high nitrogen/high water, but no significant differences were observed in the nitrogen absorption ratio and nitrogen physiological efficiency. Treatment medium nitrogen/high water was most beneficial to the coupling effects of water and nitrogen under partitioning alternate drip irrigation with plastic mulch and nitrogen fertilization.

    All human space missions require significant logistical mass and volume that add an unprecedented burden on longduration missions beyond low-Earth orbit. For these missions with limited cleaning resources, a new wardrobe must be developed to reduce this logistical burden by reducing clothing mass and extending clothing wear. The present studies have been undertaken, for the first time, to measure length of wear and to assess the acceptance of such extended wear. Garments in these studies are commercially available exercise T-shirts and shorts, routine-wear T-shirts, and longsleeved pullover shirts. Fabric composition (cotton, polyester, light-weight, superfine Merino wool, modacrylic, cotton/rayon, polyester/Cocona, modacrylic/Xstatic, modacrylic/rayon, modacrylic/lyocell/aramid), construction (open knit, tight knit, open weave, tight weave), and finishing treatment (none, quaternary ammonium salt) are the independent variables. Eleven studies are reported here: five studies of exercise T-shirts, three of exercise shorts, two of routine wear Tshirts, and one of shirts used as sleep-wear. All studies are conducted in a climate-controlled environment, similar to a space vehicle's. For exercise clothing, study participants wear the garments during aerobic exercise. For routine wear clothing, study participants wear the T-shirts daily in an office or laboratory. Daily questionnaires collected data on ordinal preferences of nine sensory elements and on reason for retiring a used garment. Study 1 compares knitted cotton, polyester, and Merino exercise T-shirts (61 participants), study 2, knitted polyester, modacrylic, and polyester/Cocona exercise T-shirts (40 participants), study 3, cotton and polyester exercise shorts, knitted and woven (70 participants), all three using factorial experimental designs with and without a finishing treatment, conducted at the Johnson Space Center, sharing study participants.

    This work focuses on the mass content of plasticizers in children's backpacks and toys, and their mass transfer from product surfaces to cotton wipes. The mass content of plasticizers in six backpacks and seven toys was measured by extracting them in tetrahydrofuran. Bis(2-ethylhexyl) terephthalate (DEHT) was the most common plasticizer, dominating the composition of plasticizers in four backpacks (average mass content in product polyvinyl chloride, 5.38 ± 1.98%-25.5 ± 3.54%) and six plastic toys (8.17 ± 1.85%-21.2 ± 1.11%). The surface of each product was wiped with three dry and three wet (by isopropanol) cotton wipes, so as to evaluate the mass transfer of plasticizers to clothing and human skin, respectively. DEHT was the most common plasticizer detected on wipe samples. There were strong correlations (backpacks r=0.90; plastic toys r=0.96) between average mass transfer of DEHT to wet wipes and its average mass content in the product. The mass transfers of the five dominant plasticizers in one backpack to both dry and wet wipes were also correlated (both r=1.00) with their mass contents. These results suggest that the mass transfer of plasticizers from products to clothing or human skin is strongly associated with their mass content.

    The first hygroscopically tunable cloth actuator is realized via impregnation of a commercial cloth template by a three dimensionally (3D) nanoporous polymer/carbon nanotube hybrid network. The nanoporous hybrid guarantees diffusion of water into the cloth actuator and amplifies the deformation scale. The cloth actuators are mechanically stable with high tensile strength. Because the commercial cotton cloth is inexpensive, such actuators capable of complex motions can be produced in a large size and scale for a wide variety of utilities (e.g. electric generators and "smart" materials).

    Astronaut clothes for exploration missions beyond low Earth orbit need to satisfy several challenges not met by the currently-used mostly-cotton clothing. A laundering system is not expected to be available, and thus soiled garments must be trashed. Jettisoning waste does not seem feasible at this time. The cabin oxygen concentration is expected to be higher than standard, and thus fabrics must better resist ignition and burning. Fabrics need to be identified that reduce logistical mass, that can be worn longer before disposal, that are at least as comfortable as cotton, and that resist ignition or that char immediately after ignition. Human factors and psychology indicate that crew well-being and morale require a variety of colors and styles to accommodate personal identity and preferences. Over the past four years, the Logistics Reduction Project under NASA's Advanced Exploration Systems Program has sponsored the Advanced Clothing System Task to conduct several ground studies and one ISS study. These studies have evaluated length of wear and personal preferences of commercially-available exercise- and routine-wear garments made from several fabrics (cotton, polyester, Merino wool, and modacrylic), woven and knitted. Note that Merino wool and modacrylic char like cotton in ambient air, while polyester unacceptably melts. This paper focuses on the two components of an International Space Station study, onboard and on the ground, with astronauts and cosmonauts. Fabrics were randomized to participants. Length of wear was assessed by statistical survival analysis, and preference by exact binomial confidence limits. Merino wool and modacrylic t-shirts were worn longer on average than polyester t-shirts. Interestingly, self-assessed preferences were inconsistent with length-of-wear behavior, as polyester was preferred to Merino wool and modacrylic.

    2013-01-01

    Background:Xinjiang is currently one of China’s three largest cotton-planting regions. Cotton plantations account for more than half of the total agricultural area in Xinjiang. All cotton plantations in Xinjiang involve film mulching. However, this leaves behind plastic film residue, which has become a very serious problem. The average residual percentage is 24%, allowing plastic film residue to seriously harm soil quality and cotton yield. At present, because cotton yield has been improved, little attention has been paid to the hazards of plastic film residue. Purpose:The paper analyzed the effects of plastic film residue accumulation on soil quality and cotton yield by setting a density gradient. The paper studied the trends in and reasons for yield variation. Differences between cotton varieties with different root depths were compared. Method: On the basis of the complete survey of plastic film residue in the production area of short-staple cotton in northern Xinjiang, 6 density plastic film residue gradients were vetted based on the number of continuous years of film mulching: 0 (0 years), 250 kg/hm2 (13 years), 500 kg/hm2 (31 years), 1000 kg/hm2 (68 years), 1500 kg/hm2 (104 years), and 2000 kg/hm2 (141 years). The weight ratio of plastic film residues of 0-25, 25-100, and 100-200 cm2 was 1:1:1, and the films were mixed into the soil at a uniform depth of 0-40 cm. Cotton varieties included“Xinluzao 33”(deep root system) and“Xinluzao 13”(shallow root system). The area of each plot was 10 m2 and each gradient was evaluated three times. Yield-related traits and the physiochemical characteristics of the soil were studied. Conclusion:The density of plastic film residue can reach 1000 kg/hm2 after 68 years of continuous film mulching, and the cotton yield of“Xinluzao 33”and“Xinluzao 13”was found to decrease by 18.1% and 13.5%, respectively. The stand establishment rates decreased by 8.4% and 16.5%, respectively, and the degrees of precocity

    The study focuses on incidents at Department of Energy (DOE) facilities involving the migration of radioactive contaminants through protective clothing. The authors analyzed 68 occurrence reports for the following factors: (1) type of work; (2) working conditions; (3) type of anti-contamination (anti-C) material; (4) area of body or clothing contaminated; and (5) nature of spread of contamination. A majority of reports identified strenuous work activities such as maintenance, construction, or decontamination and decommissioning (D&D) projects. The reports also indicated adverse working conditions that included hot and humid or cramped work environments. The type of anti-C clothing most often identified was cotton or water-resistant, disposable clothing. Most of the reports also indicated contaminants migrating through perspiration-soaked areas, typically in the knees and forearms. On the basis of their survey, the authors recommend the use of improved engineering controls and resilient, breathable, waterproof protective clothing for work in hot, humid, or damp areas where the possibility of prolonged contact with contamination cannot be easily avoided or controlled.

The methodology employed a positivistic approach and a combination of exploratory and descriptive research.   It included a qualitative exploratory phase of seven in-depth interviews and a quantitative conclusive descriptive phase of 100 face-to-face applied questionnaires.The study suggests that most responders present positive attitudes towards organic cotton fashion. There is no evidence among the responders of a direct relation between consuming organic produce and the willingness to purchase organic clothing.  However, interviewees with a higher degree of organic food consumption do exhibit higher knowledge about organic clothing, higher aspirations to enhance their quality of life and a stronger desire for hazardous chemical residue-free materials; they, as well, place a lower importance on the organic clothing premium price. The interest in environmental protection is also a characteristic of these potential customers; nevertheless, it is not necessarily related to higher organic food intakes. As with organic food, motivations for buying organic clothing are mainly related to specific characteristics of the product that directly benefit the consumer. Results have to be interpreted in light of what other studies, such as that by Carrigan et al. (2001, have revealed regarding purchase behaviour, which often remains unaffected by ethical concerns even though consumers may express willingness to purchase ethically.This research can be useful for marketers who want to better understand consumers with higher willingness to buy organic clothing. No studies existed at the time of the study

    According to the problems of plastic film without distinction as straw, the plastic film recovery rate is low, the effect is poor in removing the collected film, and plastic films are easy to wind in cotton straw chopping and a plastic film collecting combined machine in Xinjiang province, the 4JM-1500 straw chopping and plastic film collecting machine has been designed. It consists of a traction device, straw chopping device, straw conveying device, floating gear-rake institution and chain rake device, film removing device, driven system, plastic film box, and rack and wheel, etc. It can realize straw chopper returning, the straw separation with plastic film, and the plastic film recycling with one operation. This machine combining the hammer device of cotton straw chopping and scraper conveyor device, the machine could separate cotton straws and plastic film, and collect the plastic film by the floating gear-rake institution and chain rake device. It also has a good effect for ground profile modeling and improving the plastic film recovery ratio. It can remove the collected film though the air force device in the operating process, which can prevent the plastic film winding with the film stripping device and affect the work. The structure and working principle of the machine, and the parameters of working parts, and main structures were determined through the main components designed. Knife shaft speed n 3=1800~2200 r/min, straw conveying speed n1=120~150 r/min, plastic film conveying chains speed n2=60~90 r/min, film removing wind speed v 1=6.2~10.5 m/s and the working width was 1500 mm. It effectively decreased the labor cost and enhanced the plastic film collecting efficiency. Field trials demonstrated that the separation ratio of cotton straws and plastic film was 97%, the plastic film collecting ratio was 88.6%, and the film removing ratio was 89.4%under the conditions of machine operating speed of 5-5.5 km/h and straw conveying speed of 1.8m/s, which could

    2010-03-01

    A study of dry cleaning methods for plasticized PVC has been undertaken using three commercial cloths recommended for plastics artworks, in addition to cotton swabs traditionally used in art conservation. The evaluation of the cleaning has focussed on the efficiency of the cleaners, and the physical and chemical damages caused by the cleaning. The physical and chemical modifications of the PVC surface have been studied by optical microscopy, non-contact profilometry and ATR-FTIR spectroscopy, while spectrocolorimetry and non-contact profilometry have been used for evaluating the cleaning efficiency. The results have shown that the cleaner's composition and the cleaning time play an important role in damaging the plasticized PVC surface. On the contrary, it has not been completely determined if the texture of the cleaning agents' surface had an influence on the cleaning efficiency.

    All human space missions require significant logistical mass and volume that will become an excessive burden for long duration missions beyond low Earth orbit. The current International Space Station (ISS) crew wardrobe has already evolved not only to reduce some of the logistical burden but also to address crew preference. The present study was undertaken to find ways further to reduce this logistical burden while examining human response to different types of clothes. The primary objective of the study is to measure how long people can wear the same exercise garment, depending on the type of fabric and the presence of antimicrobial treatment. The secondary objective is to assess the reasons for length of wear from perceptions of clothing characteristics, including nine ordinal scales. Cardiovascular exercise was chosen as the activity in this experiment for its profuse sweating effect and because it is considered a more severe treatment applied to the clothes than every-day usage. Study garments were exercise T-shirts and shorts purchased from various vendors. Fabric construction, fabric composition, and finishing treatment were defined as the key variables. A web-based questionnaire was used for self-reported data collection. The study was divided in three balanced experiments: a cotton-polyester-wool (CPW) T-shirts study with 61 participants, a polyester-modacrylic-polyester/cocona (PMC) T-shirts study with 40 participants, and a shorts study with 70 participants. In the CPW study, the T-shirts were made of 100% cotton, or of 100% polyester or of 100% wool, and categorized into open and tight knit constructions. In the PMC study, the T-shirts were made of 100% polyester, or of 82% modacrylic, or of 95% polyester with 5% cocona fiber, without construction distinction. The shorts were made either of 100% cotton or of 100% polyester, and were knitted or woven. Some garments were treated with Bio-Protect 500 antimicrobial finish according the experimental design

    During acts of physical aggression, offenders frequently come into contact with clothes of the victim, thereby leaving traces of DNA-bearing biological material on the garments. Since tape-lifting and swabbing, the currently established methods for non-destructive trace DNA sampling from clothing, both have their shortcomings in collection efficiency and handling, we thought about a new collection method for these challenging samples. Testing two readily available electrostatic devices for their potential to sample biological material from garments made of different fabrics, we found one of them, the electrostatic dust print lifter (DPL), to perform comparable to well-established sampling with wet cotton swabs. In simulated aggression scenarios, we had the same success rate for the establishment of single aggressor profiles, suitable for database submission, with both the DPL and wet swabbing. However, we lost a substantial amount of information with electrostatic sampling, since almost no mixed aggressor-victim profiles suitable for database entry could be established, compared to conventional swabbing. This study serves as a proof of principle for electrostatic DNA sampling from items of clothing. The technique still requires optimization before it might be used in real casework. But we are confident that in the future it could be an efficient and convenient contribution to the toolbox of forensic practitioners.

    Full Text Available The currently used methods of ergonomic assessment of protective clothing depend on the subjective feeling of research participants and don’t take into consideration all aspects of its use. Therefore, more amount of work is undertaken toward the development of new research tools for the ergonomic assessment of protective clothing. Research was carried out at the Central Institute for Labour Protection – National Research Institute in Lodz. A new methodology will take into consideration a variant of reference clothing, which is related to the results of ergonomics research of protective clothing. Preparation of the reference clothing initiated by picking the appropriate fabric is based on the results of parameters influencing the physiological comfort and sensorial comfort. In the current part, results of different fabric parameters are presented, which are related to physiological comfort, i.e., the thermal resistance, water vapor resistance, hygroscopicity, and air permeability. In the next part of research, we will focus on the parameters related to objective sensorial feelings, i.e., total hand value and its components. Seven fabrics, including six cotton/polyester fabrics, diverse in terms of constituent fiber content and structure parameters (weave, thread density per 1 dm, thread linear density, mass per square meter, thickness, and Tencel/polyester fabric were tested. The best in terms of thermal resistance, water vapor resistance, and air permeability was the cotton/polyester fabric (35% cotton/65% PES with the smallest mass per square meter. This fabric also exhibits the high hygroscopicity of 7.5%, which puts it into the fourth position.

    India is one of the largest cotton-growing countries. Cotton is a fiber crop with varied applications from making tiny threads to fashionable clothing in the textile sector. In the near future, cotton crop will gain popularity as a multipurpose crop in India. The commercialization of Bt cotton in 2002 and consequently the fast adoption of Bt cotton hybrids by cotton farmers have enhanced the cotton production in India. Presently, genetically modified (GM) cotton has occupied 21.0 million hectares (mha) that comprise 14% of the global area under GM cultivation. In the coming years, improved cotton hybrids, with stacked and multiple gene events for improved fiber quality, insect resistance, drought tolerance, and herbicide tolerance, would further significantly improve the cotton production in India. With the dramatic increase in commercialization of GM crops, there is an urgent need to develop cost-effective and robust GM detection methods for effective risk assessment and management, post release monitoring, and to solve the legal disputes. DNA-based GM diagnostics are most robust assays due to their high sensitivity, specificity, and stability of DNA molecule.

  20. Burns and military clothing.

    Burn injury is a ubiquitous threat in the military environment. The risks during combat are well recognised, but the handling of fuel, oil, munitions and other hot or flammable materials during peacetime deployment and training also imposes an inherent risk of accidental burn injury. Over the last hundred years, the burn threat in combat has ranged from nuclear weapons to small shoulder-launched missiles. Materials such as napalm and white phosphorus plainly present a risk of burn, but the threat extends to encompass personnel in vehicles attacked by anti-armour weapons, large missiles, fuel-air explosives and detonations/conflagrations on weapons platforms such as ships. Large numbers of burn casualties were caused at Pearl Harbor, in Hiroshima and Nagasaki, Vietnam, during the Arab/Israeli Wars and in the Falkland Islands conflict. The threat from burns is unlikely to diminish, indeed new developments in weapons seek to exploit the vulnerability of the serviceman and servicewoman to burns. Clothing can be a barrier to some types of burn--both inherently in the properties of the material, but also by trapping air between clothing layers. Conversely, ignition of the clothing may exacerbate a burn. There is hearsay that burnt clothing products within a wound may complicate the clinical management, or that materials that melt (thermoplastic materials) should not be worn if there is a burn threat. This paper explores the incidence of burn injury, the mechanisms of heat transfer to bare skin and skin covered by materials, and the published evidence for the complication of wound management by materials. Even light-weight combat clothing can offer significant protection to skin from short duration flash burns; the most vulnerable areas are the parts of the body not covered--face and hands. Multilayered combat clothing can offer significant protection for short periods from engulfment by flames; lightweight tropical wear with few layers offers little protection. Under

    By the methods of 15N-foliar feeding and 15N dilution, a pot experiment of double-cropping wheat and cotton was conducted to study the nitrogen absorption and allocation in cotton plant under effects of wheat and cotton root mass. Three treatments were installed, i.e., no separation of wheat and cotton roots (treatment I), separation with nylon net (treatment II), and separation with plastic film (treatment III). The results showed that both the competition of 15N absorption between wheat and cotton root, and the translocation of absorbed 15N from wheat root to cotton were existed in the wheat-cotton double-cropping system. The absorbed 15N by cotton root was mostly allocated in aboveground part, and less in root. The aboveground part of cotton had the highest N utilization rate (NUR) in treatment I and the lowest one in treatment III, but the Ndff was lower in treatment I than in treatments II and III. At the early flowering stage of cotton when wheat was harvested and its straw was amended in situ, the absorbed nitrogen by cotton was mainly from the applied 15N, but not from the amended wheat straw. The allocation of absorbed 15N in different organs of cotton was quite different, being much higher in reproductive organs than in other organs. The biomass of cotton plant was also higher in treatment I than in treatments II and III.

    The cloth dehumidification is done by hot air circulation through it in dryers. The air circulation is done by a fan, run by an electrical motor, and the air temperature raise, which goes through the cloths aiming their moisture dragging, is gotten by the heat dissipation from electrical resistance. This work shows the results of an experimental modeling, examining the behavior of several kinds of cloth in a vertical suspense-type dryer, such as: polyester, cotton-spandex, flannel, blue-jeans and viscose rayon. It was analyzed the behavior of the moisture content in these cloths related to controlled-temperature-air flows, determining the needed heat to reach the required drying standards. The drying device fans were tested for the determination of their flow rate and energy consumption, establishing a flow rate versus consumption relationship. Comparative results among the various kinds of cloths are presented. (author)

    In this paper, a study of clothes drying using a heat pump drier has been carried out. The objective is to examine the performance and drying characteristics of the heat pump clothes dryer. The result of performances and drying characteristics were compared with waste heat drying system of split-type residential air conditioner (RAC). A drying chamber with volume 1 m3 integrated with heat pump component had been designed and fabricated. The heat pump operated by vapor compression cycle with power input of 800W and refrigerant R22 as a working fluid. The clothes dried made of pure cotton with initial weight varied from 3.00 kg, 5.25 kg, and 6.38 kg, respectively. The results shown that the drying time and drying rate of heat pump drier are faster than waste heat drying system. The average total performance of heat pump clothes drier is 6.56. On the other hand, SMER which is obtained 1.492 kg/kWh. These values are lower than the SMER of waste heat drying system which shown the average value of 2.492 kg/kWh. In the case of drying clothes, waste heat drying of RAC shows a better performance in comparison with heat pump drying system.

    SHANDONG Province, also called "Lu," produces traditional hand-woven cotton fabric known as "Lu Jin ("Jin" means brocade in Chinese). Lu Jin has a soft texture and is made in various designs and colors. Although machine-made cotton fabric is easy to buy here, local people, particularly women, prefer this kind of cloth woven in the old style handed down by their ancestors. In the countryside of Southwest Shandong, a girl usually begins learning how to weave cotton brocade as a child and old women are often still busy at the loom. In Jiaxiang County, for example, there are more than 10,400 looms, 74,000 spinning wheels and 90,000 capable weavers, producing 6 million meters of hand-woven fabric annually. Lu Jin is a suitable dowry for local girls. Usually, a girl begins selecting designs and weaving for her dowry two to three years before marriage. When she gets married, she carefully puts the fabric in the cupboards she will bring with

    Coleman, Beverly K.; Destaillats, Hugo; Hodgson, Alfred T.; Nazaroff, William W.

    We measured ozone consumption and byproduct formation on materials commonly found in aircraft cabins at flight-relevant conditions. Two series of small-chamber experiments were conducted, with most runs at low relative humidity (10%) and high air-exchange rate (˜20 h -1). New and used cabin materials (seat fabric, carpet, and plastic) and laundered and worn clothing fabrics (cotton, polyester, and wool) were studied. We measured ozone deposition to many material samples, and we measured ozone uptake and primary and secondary emissions of volatile organic compounds (VOCs) from a subset of samples. Deposition velocities ranged from 0.06 to 0.54 cm s -1. Emissions of VOCs were higher with ozone than without ozone in every case. The most commonly detected secondary emissions were C 1 through C 10 saturated aldehydes and the squalene oxidation products 6-methyl-5-hepten-2-one and acetone. For the compounds measured, summed VOC emission rates in the presence of 55-128 ppb (residual level) ozone ranged from 1.0 to 8.9 μmol h -1 m -2. Total byproduct yield ranged from 0.07 to 0.24 moles of product volatilized per mole of ozone consumed. Results were used to estimate the relative contribution of different materials to ozone deposition and byproduct emissions in a typical aircraft cabin. The dominant contributor to both was clothing fabrics, followed by seat fabric. Results indicate that ozone reactions with surfaces substantially reduce the ozone concentration in the cabin but also generate volatile byproducts of potential concern for the health and comfort of passengers and crew.

  14. European cloth and "tropical" skin: clothing material and British ideas of health and hygiene in tropical climates.

    Johnson, Ryan

    2009-01-01

    As Britain's imperial and colonial ambitions intensified toward the end of the nineteenth century, the preservation of white European health in tropical climates became an increasingly important concern. Since at least the seventeenth century, the "tropics" had been seen as spaces holding vast potential wealth but also death and disease. To combat these deadly but desirable landscapes, the British built a considerable commodity culture around the preservation of white European health, and for many, tropical clothing was one of the most important and essential items in their "kits." This article investigates the composition and use of such clothing in relation to British ideas of health and hygiene in tropical climates. First, it considers debates that ensued over the best material--wool, cotton, linen, silk, or a combination of these materials--and the role of "black" skin and local practice in the development of tropical clothing. Second, it demonstrates the importance of location in any discussion of tropical medicine and hygiene, and the tension and ambiguity that still surrounded British ideas of health and hygiene in the tropical colonies. Third, it argues that tropical clothing was important in the maintenance of climatic etiologies despite advances in parasitology and sanitary science. Finally, it considers the relationship of tropical clothing to the formation of a unique colonial identity. To British men and women embarking for any number of tropical destinations, proper clothing was not a banal and mundane component of their outfitting. For many, the clothing signified a departure from the safe and "civil" climes of Britain for adventure in the expanding tropical empire.

    Full Text Available Absorbency of textiles is defined as the ability of taking in a fluid in the manner of a sponge. Absorbency is required for comfort properties in so me clothes such as sportswear and underwear clothing, for drying properties in napkins, towels and bathrobes, for health concerns in some medical textiles such as bandages, gauze and absorbent cotton, and for cleaning properties in washclothes and mops. In this study five different fabric samples (three woven 100% cotton fabrics A, B and P respectively at plain, twill, and peshtamal weaving patterns and two 100% cotton terry towels T1 and T2 were tested. The absorbency properties of the samples were evaluated according to the droplet test, sinking time test and wicking height tests (pottasium chromate test. Peshtamal samples showed better absorbency results than plain and twill weaves and lower but close results to towel samples according to the droplet test, sinking time test and wicking height tests. The absorbency properties of peshtamals showed results close to towel samples. The void content of peshtamals is higher than plain and twill samples but closer and lower than towel samples. The good absorbency results of peshtamals might be due to the void content of peshtamals which is higher than plain and twill samples but closer and lower than towel samples. Peshtamals which are good in absorbency and light in weight might be used widespreadly in daily life for their high absorbency, and on travel for weight saving purposes.

    It is desirable to maintain a low bacterial count in the operating room air to prevent surgical site infection. This can be achieved by ventilation or by all staff in the operating room wearing clothes made from low-permeable material (i.e. clean air suits). We investigated whether there was a difference in protective efficacy between a single-use clothing system made of polypropylene and a reusable clothing system made of a mixed material (cotton/polyester) by testing both in a dispersal chamber and during surgical procedures. Counts of colony-forming units (cfu)/m(3) air were significantly lower when using the single-use clothing system in both settings. Copyright © 2013 The Healthcare Infection Society.

    The accumulation of phthalate esters, brominated flame retardants (BFRs) and organophosphate esters (OPEs) by clothing from indoor air and transfer via laundering to outdoors were investigated. Over 30 days cotton and polyester fabrics accumulated 3475 and 1950 ng/dm(2) ∑5phthalates, 65 and 78 ng/dm(2) ∑10BFRs, and 1200 and 310 ng/dm(2) ∑8OPEs, respectively. Planar surface area concentrations of OPEs and low molecular weight phthalates were significantly greater in cotton than polyester and similar for BFRs and high molecular weight phthalates. This difference was significantly and inversely correlated with KOW, suggesting greater sorption of polar compounds to polar cotton. Chemical release from cotton and polyester to laundry water was >80% of aliphatic OPEs (log KOW phthalates (log KOW 4-6), and phthalates (log KOW > 8) and BFRs (log KOW > 6). These results support the hypothesis that clothing acts an efficient conveyer of soluble semivolatile organic compounds (SVOCs) from indoors to outdoors through accumulation from air and then release during laundering. Clothes drying could as well contribute to the release of chemicals emitted by electric dryers. The results also have implications for dermal exposure.

    1979-06-01

    Occupational exposures to radiation from tritium received at present nuclear facilities and potential exposures at future fusion reactor facilities demonstrate the need for improved protective clothing. Important areas relating to increased protection factors of tritium protective ventilation suits are discussed. These areas include permeation processes of tritium through materials, various tests of film permeability, selection and availability of suit materials, suit designs, and administrative procedures. The phenomenological nature of film permeability calls for more standardized and universal test methods, which would increase the amount of directly useful information on impermeable materials. Improvements in suit designs could be expedited and better communicated to the health physics community by centralizing devlopmental equipment, manpower, and expertise in the field of tritium protection to one or two authoritative institutions.

    This is a laboratory investigation on the emissions from batch combustion of representative infectious ("red bag") medical waste components, such as medical examination latex gloves and sterile cotton pads. Plastics and cloth account for the majority of the red bag wastes by mass and, certainly, by volume. An electrically heated, horizontal muffle furnace was used for batch combustion of small quantities of shredded fuels (0.5-1.5 g) at a gas temperature of approximately 1000 degrees C. The residence time of the post-combustion gases in the furnace was approximately 1 s. At the exit of the furnace, the following emissions were measured: CO, CO2, NOx, particulates and polynuclear aromatic compounds (PACs). The first three gaseous emissions were measured with continuous gas analyzers. Soot and PAC emissions were simultaneously measured by passing the furnace effluent through a filter (to collect condensed-phase PACs) and a bed of XAD-4 adsorbent (to capture gaseous-phase PACs). Analysis involved soxhlet extraction, followed by gas chromatography-mass spectrometry (GC-MS). Results were contrasted with previously measured emissions from batch combustion of pulverized coal and tire-derived fuel (TDF) under similar conditions. Results showed that the particulate soot) and cumulative PAC emissions from batch combustion of latex gloves were more than an order of magnitude higher than those from cotton pads. The following values are indicative of the relative trends (but not necessarily absolute values) in emission yields: 26% of the mass of the latex was converted to soot, 11% of which was condensed PAC. Only 2% of the mass of cotton pads was converted to soot, and only 3% of the weight of that soot was condensed PAC. The PAC yields from latex were comparable to those from TDF. The PAC yields from cotton were higher than those from coal. A notable exception to this trend was that the three-ring gas-phase PAC yields from cotton were more significant than those from latex

    Metals in textile products and clothing are used for many purposes, such as metal complex dyes, pigments, mordant, catalyst in synthetic fabrics manufacture, synergists of flame retardants, antimicrobials, or as water repellents and odour-preventive agents. When present in textile materials, heavy metals may mean a potential danger to human health. In the present study, the concentrations of a number of elements (Al, As, B, Ba, Be, Bi, Cd, Co, Cr, Cu, Fe, Hg, Mg, Mn, Mo, Ni, Pb, Sb, Sc, Se, Sm, Sn, Sr, Tl, V, and Zn) were determined in skin-contact clothes. Analysed clothes were made of different materials, colours, and brands. Interestingly, we found high levels of Cr in polyamide dark clothes (605 mg/kg), high Sb concentrations in polyester clothes (141 mg/kg), and great Cu levels in some green cotton fabrics (around 280 mg/kg).

    The Universal Thermal Climate Index (UTCI) was conceived as a thermal index covering the whole climate range from heat to cold. This would be impossible without considering clothing as the interface between the person (here, the physiological model of thermoregulation) and the environment. It was decided to develop a clothing model for this application in which the following three factors were considered: (1) typical dressing behaviour in different temperatures, as observed in the field, resulting in a model of the distribution of clothing over the different body segments in relation to the ambient temperature, (2) the changes in clothing insulation and vapour resistance caused by wind and body movement, and (3) the change in wind speed in relation to the height above ground. The outcome was a clothing model that defines in detail the effective clothing insulation and vapour resistance for each of the thermo-physiological model's body segments over a wide range of climatic conditions. This paper details this model's conception and documents its definitions.

    Based on data gathered through a questionnaire survey with 3,544 respondents in six largest cities in China, the clothing expenditures of Chinese consumers and influential factors are investigated in this paper. It was found that regional differences exist sig nificantly among the cities, possibly due to differences in economy,customs, culture and other factors It was also found that the demographic and soionomic factors including age, gender, marital staus , education level,occupation, and household income have a significant influence on clothing expenditures. Further, the interactive influences of geographic variable with demographic and socioeconomic variables on the clothing expenditures were ex amined. The findings should have useful implications for segmenting Chinese consumers and developing marketing strategies in China.

    Cotton and polyester, physically and chemically different fabrics, were characterized for sorption of gas-phase polybrominated diphenyl ethers (PBDEs). Scanning electron microscopic (SEM) images and BET specific surface area (BET-SSA) analysis showed cotton's high microsurface area; NMR analysis showed richness of hexose- and aromatic-carbon in cotton and polyester, respectively. Cotton and polyester sorbed similar concentrations of gas-phase PBDEs in chamber studies, when normalized to planar surface area. However, polyester concentrations were 20–50 times greater than cotton when normalized to BET-SSA, greater than the 10 times difference in BET-SSA. The difference in sorption between cotton and polyester is hypothesized to be due to ‘dilution’ due to cotton's large BET-SSA and/or greater affinity of PBDEs for aromatic-rich polyester. Similar fabric-air area normalized distribution coefficients (K'{sub D}, 10{sup 3} to 10{sup 4} m) for cotton and polyester support air-side controlled uptake under non-equilibrium conditions. K'{sub D} values imply that 1 m{sup 2} of cotton or polyester fabrics would sorb gas-phase PBDEs present in 10{sup 3} to 10{sup 4} m{sup 3} of equivalent air volume at room temperature over one week, assuming similar air flow conditions. Sorption of PBDEs to fabrics has implications for their fate indoors and human exposure. - Highlights: • Sorption of gas-phase PBDEs by cotton and polyester fabrics • Similar sorption to cotton and polyester per unit planar surface area • Greater sorption by polyester/BET-SSA; cotton's dilution or polyester’s affinity • 1 m{sup 2} fabric sorbs PBDEs in 10{sup 3} to 10{sup 4} m{sup 3} of equivalent air volume • Clothing likely a large indoor sink of PBDEs and influence human exposure.

    The fisherman's work environment consists of many potential risks. A study of occupational accidents in the Norwegian fishing industry in the nine-year period from 1998 to 2006 shows that more than 3/4 of the deaths were caused by loss of fishing vessel or man-overboard accidents. Furthermore, the greatest risk of drowning is found in the smallest fleet. The aim of our project was to develop safer work clothing and through this contribute to a reduction in work accidents and injuries in the fishing fleet. We considered that it is possible to produce protective work clothing that satisfies a specification of requirements covering the fishermen's needs for protection and comfort during work. An end user-centred process including twenty-three personal interviews and a questionnaire was used to clarify the fishermen's needs and wishes before detailed design and product development. We identified an overview of all the fishermen's needs for protection during work, and produced a prioritised list of functional requirements for the clothing. The results show that the clothing previously preferred by fishermen does not satisfy all the users' demands for safety, functionality and comfort. These demands have been taken into consideration when designing improved work clothing for the fishing fleet. A selected number of prototypes were developed on the basis of the established specification of requirements. The prototypes were evaluated according to the users' requirements through tests in SINTEF's Work Physiology Laboratory and on board fishing vessels. The results demonstrate that the new protective clothing satisfies the fishermen's requirements.

    detection rate was not high and the speed of the detection was slow. Because the method was based on the calculation of the target size and distribution, or in the image acquisition, the laser light must project from some special angles of the sample surface for the camera can obtain the reflected light from the white foreign fibers. In this study, the image contrast of the white foreign fibers and the cotton background was first quantized by the calculation of the average pixel value in a frame of the laser image. Then, under the illumination of a line laser at a fixed power and wavelength, the images of 12 kinds of typical white foreign fibers on the cotton surface were obtained by a camera with a fixed aperture with different lengths of exposure time. Finally, the relationship between the lengths of different imaging exposure time and the image contrast was analyzed. It was found that there was a shared wave crest in all of the relationship curves and imaging in the exposure time of the wave crest in the same frame image. The gray level of the white foreign fibers had reached a saturated status, but the gray level of cotton was still unsaturated. Thus, using an optimized exposure time, the difference of the gray level of the laser images can be used for the detection of the white foreign fibers in cotton, including white paper, white plastic film, white semitransparent plastic mulch, white cloth, white density foam plastic, white nylon cord, white cotton string, white plastic cord, white plastic cardboard, white semitransparent polypropylene bags, white polyethylene foamed sheets, and white feathers. The experimental results indicated that, by a simple binary segmentation algorithm, using the images obtained under the illumination of the line laser at the wavelength of 650 nm, a power of 0.8 W, and by the camera aperture of 8C with an exposure time of 1.6 ms, the 12 kinds of white foreign fibers can be easily distinguished from cotton. In Matlab, the processing time of a

    Nanosilica-chitosan composite coating on cotton fabrics has been prepared by sol-gel method. The sol-gel procedure allows coating of material on nanometer scale, which several commonly used coating procedure cannot achieve. In addition, sol-gel coating technique can be applied to system without disruption of their structure functionaly. The coating were produced via hidrolysis and condensation of TEOS and GPTMS and then mixed with chitosan. The composite coating on cotton fabrics were characterized with X-Ray Diffraction and Scanning Electron microscopy (SEM) method. The result showed that the coating not changed or disrupted the cotton stucture. The coating result in a clear transparent thin layer on cotton surface. The nanocomposite coating has new applications in daily used materials, especially those with low heat resistance, such as textiles and plastics, and as an environmentally friendly water-repellent substitute for fluorine compounds.

    Human eyes have a remarkable ability to recognize hundreds of colour shades, which has stimulated the use of colorants, especially for clothing, but toxicological studies have shown that some textile dyes can be hazardous to human health. Under conditions of intense perspiration, dyes can migrate from coloured clothes and penetrate into human skin. Garments made from cotton fabrics are the most common clothing in tropical countries, due to their high temperatures. Aiming to identify safe textile dyes for dyeing cotton fabrics, the genotoxicity [in vitro Comet assay with normal human dermal fibroblasts (NHDF), Tail Intensity] and mutagenicity [Salmonella/microsome preincubation assay (30min), tester strains TA98, TA100, YG1041 and YG1042] of Reactive Blue 2 (RB2, CAS No. 12236-82-7, C.I. 61211) and Reactive Green 19 (RG19, CAS No. 61931-49-5, C.I. 205075) were evaluated both in the formulated form and as extracted from cotton fibres using different artificial sweats. Both the dyes could migrate from cotton fibres to sweat solutions, the sweat composition and pH being important factors during this extraction. However, the dye sweat solutions showed no genotoxic/mutagenic effects, whereas a weak mutagenic potential was detected by the Ames test for both dyes in their formulated form. These findings emphasize the relevance of textile dyes assessment under conditions that more closely resemble human exposure, in order to recognize any hazard.

  3. Modeling Neanderthal clothing using ethnographic analogues.

    Wales, Nathan

    2012-12-01

    Although direct evidence for Neanderthal clothing is essentially nonexistent, information about Paleolithic clothing could provide insights into the biological, technological, and behavioral capabilities of Neanderthals. This paper takes a new approach to understanding Neanderthal clothing through the collection and analysis of clothing data for 245 recent hunter-gatherer groups. These data are tested against environmental factors to infer what clothing humans tend to wear under different conditions. Beta regression is used to predict the proportion of the body covered by clothing according to a location's mean temperature of the coldest month, average wind speed, and annual rainfall. In addition, logistic regression equations predict clothing use on specific parts of the body. Neanderthal clothing patterns are modeled across Europe and over a range of Pleistocene environmental conditions, thereby providing a new appreciation of Paleolithic behavioral variability. After accounting for higher tolerances to cold temperatures, it is predicted that some Neanderthals would have covered up to 80% of their bodies during the winter, probably with non-tailored clothing. It is also likely that some populations covered the hands and feet. In comparison with Neanderthals, Upper Paleolithic modern humans are found to have worn more sophisticated clothing. Importantly, these predictions shed new light on the relationship between Neanderthal extinction and their simple clothing.

    Matching clothes is a challenging task for many blind people. In this paper, we present a proof of concept system to solve this problem. The system consists of 1) a camera connected to a computer to perform pattern and color matching process; 2) speech commands for system control and configuration; and 3) audio feedback to provide matching results for both color and patterns of clothes. This system can handle clothes in deficient color without any pattern, as well as clothing with multiple colors and complex patterns to aid both blind and color deficient people. Furthermore, our method is robust to variations of illumination, clothing rotation and wrinkling. To evaluate the proposed prototype, we collect two challenging databases including clothes without any pattern, or with multiple colors and different patterns under different conditions of lighting and rotation. Results reported here demonstrate the robustness and effectiveness of the proposed clothing matching system.

  8. Clothes Dryer Automatic Termination Evaluation

    Energy Technology Data Exchange (ETDEWEB)

    TeGrotenhuis, Ward E.

    2014-10-01

    Volume 2: Improved Sensor and Control Designs Many residential clothes dryers on the market today provide automatic cycles that are intended to stop when the clothes are dry, as determined by the final remaining moisture content (RMC). However, testing of automatic termination cycles has shown that many dryers are susceptible to over-drying of loads, leading to excess energy consumption. In particular, tests performed using the DOE Test Procedure in Appendix D2 of 10 CFR 430 subpart B have shown that as much as 62% of the energy used in a cycle may be from over-drying. Volume 1 of this report shows an average of 20% excess energy from over-drying when running automatic cycles with various load compositions and dryer settings. Consequently, improving automatic termination sensors and algorithms has the potential for substantial energy savings in the U.S.

    A series of field tests exposing mannequins clothed with civilian clothing to a 3m x 3m square liquefied natural gas (LNG) pool fire was conducted. Both single layer clothing and double layer clothing were used. The radiant heat flux incident outside the clothing and incident on the skin covered by clothing were measured using wide-angle radiometers, for durations of 100-200 s (per test). The levels of heat flux incident on the clothing were close to 5 kW/m(2). The magnitude of the radiant heat attenuation factor (AF) across the thickness was determined. AF varies between 2 and higher for cotton and polyester clothing (thickness 0.286-1.347 mm); AF value of 6 was measured for 1.347 mm thickness. Single sheet newspaper held about 5 cm in front of mannequins and exposed to incident flux of 5 kW/m(2) resulted in AF of 5, and AF of 8 with double sheets. AF decreases linearly with increasing heat flux values and linearly increases with thickness. The author exposed himself, in normal civilian clothing (of full sleeve cotton/polyester shirt and jean pants), to radiant heat from a LNG fire. The exposure was for several tens of seconds to heat flux levels ranging from 3.5 kW/m(2) to 5(+) kW/m(2) (exposure times from 25s to 97 s at average heat flux values in the 4 kW/m(2) and 5 kW/m(2)range). Occasionally, he was exposed to (as high as) 7 kW/m(2) for durations of several seconds. He did not suffer any unbearable or even severe pain nor did he experience blisters or burns or any other injury on the unprotected skin of his body. The incident heat fluxes on the author were measured by a hand-held radiometer (with digital display) as well as by strapped on wide-angle radiometers connected to a computer. He could withstand the US regulatory criterion of 5 kW/m(2) (for 30 s) without suffering any damage or burns. Temperature measured on author's skin covered by clothing did not rise above the normal body temperature even after 200 s of exposure to 4 kW/m(2) average heat flux.

    In this study, different conventional personal protection devices (fibrous filters, cartridges for respirators, protective clothing, and gloves) well qualified for micron particles were tested with graphite nanoparticles ranging from 10 to 100 nm (electrical mobility diameter). For this purpose, two specific test benches were designed: one for filter-based devices which are tested under a controlled air flow and other for gloves and protective clothing based on the "through diffusion method." The penetration versus particle size shows for most tested filter media the behavior predicted by the theoretical Brownian capture: penetration decreases when particle diameter decreases. No thermal rebound was detected until 10 nm for graphite nanoparticles. Protective clothes were tested by two methods and same trends were obtained. Nonwoven fabrics (air-tight materials) are much more efficient against nanoparticles than cotton and paper. Gloves tested by "through diffusion technique," in static condition seem to efficiently protect against graphite nanoparticles in spite of their important porosity.

    One activity that has been performed by human beings for a long time is washing clothes. Before the invention of the washing machine, clothes were washed by hand and then wrung before drying in the open air. When observed carefully, the wringing of cloth presents some interesting phenomena. However, there are no reports on the physical modelling of this very old activity. This paper reports a simple model to explain the discharge of water from clothes when squeezed. A simple tool was also designed to retrieve data to confirm the theory. We found that the theoretical predictions accurately explained the experimental results. The experiments were conducted on two types of cloth: towels and batik cloth. We also obtained a universal curve to which all the data converged.

    2008-01-01

    Simulating the mechanical behavior of a cloth is a very challenging and important problem in computer animation. The models of bending in most existing cloth simulation approaches are taking the assumption that the cloth is little deformed from a plate shape.Therefore, based on the thin-plate theory, these bending models do not consider the condition that the current shape of the cloth under large deformations cannot be regarded as the approximation to that before deformation, which leads to an unreal static bending. [This paper introduces a dynamic bending model which is appropriate to describe large out-plane deformations such as cloth buckling and bending, and develops a compact implementation of the new model on spring-mass systems. Experimental results show that wrinkles and folds generated using this technique in cloth simulation, can appear and vanish in a more natural way than other approaches.

    Entomopathogenic fungi are potential candidates for use in integrated vector management. However, efficient delivery systems for these fungi need to be investigated. It is known that adult mosquitoes are attracted to dark surfaces, and therefore, black cotton cloths impregnated with Metarhizium anisopliae alone or in combination with the insecticide imidacloprid (IMI) were tested under laboratory conditions. Black cloths impregnated with fungus were also tested in large-cage trials under natural extradomicile conditions. Blood-fed Rockefeller and wild-type strain Aedes aegypti had higher levels of survival when compared with sucrose-fed counterparts following exposure to fungus-impregnated cloths. However, when blood-fed A. aegypti were exposed to a combination of M. anisopliae + IMI, the survival rates were statistically equal to those of sucrose-fed females. Large-cage trials showed significant decreases in A. aegypti survival following a minimum 12 h exposure of the mosquitoes to fungus-impregnated cloths. Increased exposure times results in further reductions in survival. The synergism between M. anisopliae and IMI resulted in reduced survival rates independent of feeding regime under laboratory conditions. Fungus-impregnated cloths tested under simulated field conditions, considered to be unfavourable for fungal infection, resulted in significant reductions in adult A. aegypti survival. We are currently testing the combined use of fungi and insecticides against blood-fed insects under simulated field conditions. The use of fungus-impregnated cotton cloths is a promising point source application method for the control of adult Aedes aegypti, and this strategy could be incorporated into an integrated vector management programme aiming to reduce the incidence of dengue fever. © 2013 The Society for Applied Microbiology.

    Full Text Available Macro- and crystalline structure, as well as chemical composition of fibers related to various types and sorts of Israeli cottons, both white and naturally colored, were investigated. The differences in structural parameters and chemical compositions of the cotton fibers were evaluated. Samples of cotton of the “Pima”-type had long, thin and strong fibers with highly ordered supermolecular structure. Fibers of middle-long and hybrid cottons had some lower-ordered structural organization in comparison to long-length cotton, while fibers of naturally colored cotton were characterized with disordered supermolecular and crystalline structure. Dependence of tensile strength on orientation of nano-fibrils towards the fiber axis was found. Conditions of cellulose isolation from the different cotton fibers were studied. Structural characteristics of isolated cotton celluloses and obtained MCC are discussed.

    2013-01-01

    A field experiment with complete combination design was conducted to study the effects of partitioning alternative drip irrigation with plastic mulch and nitrogen fertilization on the dry matter accumulation and nitrogen use efficiency of cotton plant. Three levels of irrigation (260, 200, and 140 mm) and of nitrogen fertilizer (270, 180, and 90 kg·hm-2) were installed. The cotton dry mass was the highest in treatments medium nitrogen/high water and high nitrogen/high water. As compared with that in high nitrogen/high water treatment, the nitrogen use efficiency for dry matter accumulation in medium nitrogen/high water treatment was increased by 34. 0% -44. 6% , with an average of 34.7% , while the water use efficiency was decreased by 6.4% -10.7% , aver-agely 10. 2%. As for the nitrogen accumulation in cotton plant, the nitrogen use efficiency was the highest in medium nitrogen/high water treatment, and the water use efficiency was the highest in high nitrogen/medium water treatment. Compared with high nitrogen/high water treatment, medium nitrogen/high water treatment increased the nitrogen use efficiency for cotton nitrogen accumulation by 29.0% -41. 7% , but decreased the water use efficiency for cotton nitrogen accumulation by 5. 5% -14. 0%. Among the treatments of coupling water and nitrogen of higher cotton yield, treatment medium nitrogen/high water had the higher cotton nitrogen recovery rate, nitrogen agronomic efficiency, and apparent use efficiency than the treatments high nitrogen/medium water and high nitrogen/high water, but no significant differences were observed in the nitrogen absorption ratio and nitrogen physiological efficiency. Treatment medium nitrogen/high water was most beneficial to the coupling effects of water and nitrogen under partitioning alternate drip irrigation with plastic mulch and nitrogen fertilization.%设置高水(260 mm)、中水(200 mm)、低水(140 mm)3水平的灌水量和高氮(270 kg·hm-2)、中氮(180 kg·hm-2)

    Cotton continues to be a crop of great economic importance in many developing and some developed countries. Cotton plants expressing the Bt gene to deter some of the major pests have been enthusiastically and widely accepted by the farmers in three of the major producing countries, i.e., China, India, and the USA. Considering the constraints related to its production and the wide variety of products derived from the cotton plant, it offers several target traits that can be improved through genetic engineering. Thus, there is a great need to accelerate the application of biotechnological tools for cotton improvement. This requires a simple, yet robust gene delivery/transformant recovery system. Recently, a protocol, involving large-scale, mechanical isolation of embryonic axes from germinating cottonseeds followed by direct transformation of the meristematic cells has been developed by an industrial laboratory. However, complexity of the mechanical device and the patent restrictions are likely to keep this method out of reach of most academic laboratories. In this chapter, we describe the method developed in our laboratory that has undergone further refinements and involves Agrobacterium-mediated transformation of cotton cells, selection of stable transgenic callus lines, and recovery of plants via somatic embryogenesis.

    Full Text Available Concern on biodegradable plastic film is increasing because of pollution problems caused by the plastic films currently used. The objective of this field experiment is to evaluate the effect of two thicknesses of polyactic acid-degradable film on soil temperature and cotton yield. The results showed that small holes appeared in the polyactic acid-degradable film at 17~22 d after it was installed. Burst period appeared about 60 d after installation. Splits were observed in the polyactic acid-degradable film at 130 d after installation. Soil temperatures rose slowly under polyactic acid-degradable film during the cotton seedling stage. Daytime soil temperatures were 0.8℃ and 6.2℃ lower under 18μm and 15μm thick polyactic acid-degradable film than non-degradable plastic film(CK, respectively. Nighttime soil temperatures under the polyactic acid-degradable film were about 1℃ warmer than CK. There was no significant difference in cotton yields between the 18μm polyactic acid degradable film treatment and CK. In contrast, yields in the 15μm degradable plastic film treatment were 8.9% less than that in CK. This study indicated that 18μm polyactic acid degradable plastic film had good degradability and no negative effect on cotton growth. The 18μm polyactic acid degradable plastic film can replace ordinary plastic film in agricultural production.

    A combination of chemical and mechanical treatment of cotton produced cotton powder (fibrils) with a mean diameter of 97 nm is analyzed by Laser Particle Size Analyzer. Transmission Electron Micro scope (TEM) study showed that the diameter of the fibrils was about 10-30 nm and the length was from 70nm to over 400 nm. The powder was then coated onto fabrics (100% polyester fabric, 100% wool fabric and 100% cotton fabric). Scanning Electron Microscope (SEM) study showed that cotton fibrils were adhered to the surface of treated fabrics (fibers). The ultraviolet protection factor (UPF) value (AS/NZS 4399:1996) for cotton fabrics increased about 20% after the treatment. This implies that the treated samples give a better protection from UV light. The moisture management test (MMT) of the fabrics such as wetting time at bottom, top maximum absorption rate, bottom maximum absorption rate, bottom maximum wetted radius and bottom spreading speed, et al., showed that there were significant changes after the treatment. These changes gave better moisture management ability to the treated fabrics and thus made the fabric more comfortable. However, Wide-angle X-ray Diffraction and Fourie Transform Infrared Spectroscopy analysis proved that supermolecular structure and chemical structure of treated fabrics were the same as the original fabrics. Other properties of the treated fabric such as thermal conductivity, wrinkle recovery, hand, et al., did not change. This implied that the basic function of the treated fabrics for the clothing industry was the same as untreated fabrics. This study is a foundation for further researches on textile application.

    The paper studies the obtaining of bioactive textiles using chitosan-coated fabrics, in which biologically active substances contained by Viola Tricolor (VT) - an extract of three Viola species (Violaceae) - were immobilized. Chitosan was applied on cotton fabric or on chemically modified cotton (having reactive -CHO or carboxymethyl groups), as tripolyphosphate (TPP) crosslinked fine particles, or by use of glutaraldehyde crosslinking agent. The amount of VT retained on the fabrics was found to depend on the procedure of chitosan application on the cotton. The obtained bioactive textiles are expected to have antioxidant activity due to the biologically active substances from VT; they can be used for obtaining clothes for people with allergies or other skin problems, assuring a controlled release of biomolecules. The study focuses on the in vitro release of VT retained on the fabrics, as well as on its antioxidant activity.

    Restrictions of preterm newborns' movements could have consequences ranging from stress enhancement to impairment of their motor development. Therefore, ability to freely express motor activities appears crucial for their behavioural and physiological development. Our aim was to evaluate behavioural issues of two types of clothing used in NICU. We observed 18 healthy 34-37 post-conception week-old preterm newborns, during resting periods, when they were undisturbed by any interventions. Newborns wore either light clothing (bodysuit and a light wrapping) or heavy clothing (pyjamas, cardigan and sleep-sack). The percentages of time each subject spent in different postures were compared between clothing situations. Arm and hand postures differed in relation to clothing: babies bent their arms more and held their hands nearer their heads when in bodysuits than when in sleepwear. Consequently, babies in bodysuits spent more time touching their body or their environment whereas the others generally were touching nothing. Self-touch is an important way to comfort one's self. Heavy clothing may impair self-soothing behaviours of preterm newborn babies that already lack other forms of contact. Results suggest that more attention should be paid to apparently routine and marginal decisions such as choice of clothes.

    Electric energy is one of the primary energy sources consumpted in cotton textile processing. Current energy cost rate is reported about 8-10% in the total production cost of an ordinary textile product manufactured in Turkey. Significantly important share of this energy cost is electric energy. The aim of this paper was to investigate unit electric energy consumption of cotton textile processing stages using real-time measurements method. Actual and estimated Specific Energy Consumption (SEC) values for electric energy was calculated in the cotton textile processing stages of spinning, warping-sizing, weaving, wet processing and clothing manufacturing. Actual electric energy consumption data are gathered from monthly records of the involved plant managements. Estimated electric energy consumption data is gathered through on-site measurement. Actual and estimated electric energy consumption data and monthly production quantities of the corresponding months are used to facilitate specific electric energy consumption of the plants. It is found that actual electric energy consumption amount per unit textile product is higher than the estimated electric energy consumption amount per unit textile product of each involved textile processing stages.

    This paper advances a new concept of textile-meltglue cloth, and introduces the readers to the basic principle of melt-glue cloth. On the basis of melt spinning, the spinneret can be replaced by a spinning device that consists of an outer spinneret (a loop)and an inner spinneret ( a round plate), and between them there is an interval circle on which the centers of the holes are evenly distributed. When the machine is running, the outer spinneret (or the inner one) is fixed, the inner spinneret (or the outer one)is spinning, and a columnar net will be obtained.Then it will be excided with the help of a cutter in transporting it. Finally the once-forming melt-glue cloth will be produced. Compared with the traditional woven fabric, melt-glue cloth has a lot of special features and a bright future of application.

    Manual recovery of spray paints from textiles using a microscope, the routine method in many laboratories, is often laborious. Beating the clothing with a plastic rod, the routine method used for recovery of glass traces within the authors' laboratory, is proposed as an alternative. The efficiency of the method was evaluated by spray tests with fluorescent paint. In these tests, paint particles in the acquired debris samples, as well as those remaining on the textiles, were investigated. The results show that beating is an efficient way to recover and concentrate paint particles. A good efficiency for jeans fabric and rough knitwear is reported. The results appeared to be less satisfactory for smooth woven fabric. Application of the method in casework was effective for graffiti paints as well as for flaked car paint. © 2014 American Academy of Forensic Sciences.

    2015-04-01

    Textiles play an important role in our daily life, and textile production is one of the oldest industries. In the manufacturing chain from natural and/or synthetic fibers to the final clothing products, the use of many different chemicals is ubiquitous. A lot of research has focused on chemicals in textile wastewater, but the knowledge of the actual content of harmful chemicals in clothes sold on the retail market is limited. In this paper, we have focused on eight benzothiazole and benzotriazole derivatives, compounds rated as high production volume chemicals. Twenty-six clothing samples of various textile materials and colors manufactured in 14 different countries were analyzed in textile clothing using liquid chromatography tandem mass spectrometry. Among the investigated textile products, 11 clothes were for babies, toddlers, and children. Eight of the 11 compounds included in the investigation were detected in the textiles. Benzothiazole was present in 23 of 26 investigated garments in concentrations ranging from 0.45 to 51 μg/g textile. The garment with the highest concentration of benzothiazole contained a total amount of 8.3 mg of the chemical. The third highest concentration of benzothiazole (22 μg/g) was detected in a baby body made from "organic cotton" equipped with the "Nordic Ecolabel" ("Svanenmärkt"). It was also found that concentrations of benzothiazoles in general were much higher than those for benzotriazoles. This study implicates that clothing textiles can be a possible route for human exposure to harmful chemicals by skin contact, as well as being a potential source of environmental pollutants via laundering and release to household wastewater.

    In this study, cotton stalk (CS), cotton waste (CW) and cotton dust (CD) was used as sorbents to remove methylene blue (MB) from aqueous solution by batch sorption technique. Effects of initial dye concentration, solution pH, solution temperature and sorbent dose on sorption were studied. It was seen that the removal of methylene blue increased with increasing initial dye concentration (from 25 to 100 mg/l), solution pH (from 5 to 10), solution temperature (from 20 to 50 deg. C) and sorbent dose (from 0.25 to 1.50 g/50 ml). The maximum dye removal was reached at 90 min. Sorption isotherms were analyzed by Langmuir and Freundlich models at different temperatures of 20, 30, 40 and 50 deg. C, and the results were discussed in detail. Moreover, the thermodynamics of sorption were also studied. It was found that the values of standard free energy ({Delta}G{sup o}) were positive for cotton stalk and negative for cotton waste and cotton dust. The values of standard enthalpy ({Delta}H{sup o}) and entropy ({Delta}S{sup o}) were found to be positive, and the obtained results were interpreted in detail. The results of this study showed that cotton stalk, cotton waste and cotton dust could be employed as effective and low-cost materials for the removal of dyes from aqueous solution.

    Humans should avoid prolonged exposure to the Sun during the warm subperiod of the year with naturally high solar UV level. One of the known recommendations to avoid excessive UV radiation is wearing clothes with UV protection additives. However there is an important question: how do we get an adequate solar UV radiation, which maintains a healthy status of vitamin D, without facing overexposure risks? It is found that some kind of 100% cotton knitted fabric, used in the production of normal daily clothing, has ∼15% transmittance of solar UV. Model studies show that a garment made of this fabric allows larger synthesis of vitamin D3 in human body without the erythema risks (skin redness). Thus the adequate level of vitamin D could be attained safely by a person exposing only small part of the body (face, palms) during the period (May-August) of the year.

    Zhang, Mingmin; Pan, Zhigengx; Mi, Qingfeng

    Physically based cloth simulation has been challenging the graphics community for more than three decades. With the developing of virtual reality and clothing CAD, it has become the key technique of virtual garment and try-on system. Although it has received considerable attention in computer graphics, due to its flexible property and realistic feeling that the textile engineers pay much attention to, there is not a successful methodology to simulate cloth both in visual realism and physical accuracy. We present a new anisotropic textile modeling method based on physical mass-spring system, which models the warps and wefts separately according to the different material fabrics. The simulation process includes two main steps: firstly the rigid object simulation and secondly the flexible mass simulation near to be equilibrium. A multiresolution modeling is applied to enhance the tradeoff fruit of the realistic presentation and computation cost. Finally, some examples and the analysis results show the efficiency of the proposed method.

    This study investigated the effects of clothing fabric on human skin microcirculation. Once skin is covered with a clothing fabric, human sensations, namely, coolness, warmth, softness, and roughness, are amused immediately, and the cutaneous micrecireulation may be changed consequently. Since the complex relationships of the human skin, the environment, and the clothing, there is few publication focusing on the physiological responses of the skin to the fabrics. In this paper, a Laser Doppler Flowmetry (LDF) was used to test the dynamic responses of the skin blood flow when the fabric was placed on the skin. Effects of different fabrics on the skin blood flux were investigated. The results show that cold stimulation of fabric has remarkable influences on the skin blood flux, and the surface properties of fabric are of importance to affect the human skin blood flow.

    Full Text Available Abstract Background Cultivated cotton is an annual fiber crop derived mainly from two perennial species, Gossypium hirsutum L. or upland cotton, and G. barbadense L., extra long-staple fiber Pima or Egyptian cotton. These two cultivated species are among five allotetraploid species presumably derived monophyletically between G. arboreum and G. raimondii. Genomic-based approaches have been hindered by the limited variation within species. Yet, population-based methods are being used for genome-wide introgression of novel alleles from G. mustelinum and G. tomentosum into G. hirsutum using combinations of backcrossing, selfing, and inter-mating. Recombinant inbred line populations between genetics standards TM-1, (G. hirsutum × 3-79 (G. barbadense have been developed to allow high-density genetic mapping of traits. Results This paper describes a strategy to efficiently characterize genomic variation (SNPs and indels within and among cotton species. Over 1000 SNPs from 270 loci and 279 indels from 92 loci segregating in G. hirsutum and G. barbadense were genotyped across a standard panel of 24 lines, 16 of which are elite cotton breeding lines and 8 mapping parents of populations from six cotton species. Over 200 loci were genetically mapped in a core mapping population derived from TM-1 and 3-79 and in G. hirsutum breeding germplasm. Conclusion In this research, SNP and indel diversity is characterized for 270 single-copy polymorphic loci in cotton. A strategy for SNP discovery is defined to pre-screen loci for copy number and polymorphism. Our data indicate that the A and D genomes in both diploid and tetraploid cotton remain distinct from each such that paralogs can be distinguished. This research provides mapped DNA markers for intra-specific crosses and introgression of exotic germplasm in cotton.

  1. Heat Pump Clothes Dryer Model Development

    Energy Technology Data Exchange (ETDEWEB)

    Shen, Bo [ORNL

    2016-01-01

    A heat pump clothes dryer (HPCD) is an innovative appliance that uses a vapor compression system to dry clothes. Air circulates in a closed loop through the drum, so no vent is required. The condenser heats air to evaporate moisture out of the clothes, and the evaporator condenses water out of the air stream. As a result, the HPCD can achieve 50% energy savings compared to a conventional electric resistance dryer. We developed a physics-based, quasi-steady-state HPCD system model with detailed heat exchanger and compressor models. In a novel approach, we applied a heat and mass transfer effectiveness model to simulate the drying process of the clothes load in the drum. The system model is able to simulate the inherently transient HPCD drying process, to size components, and to reveal trends in key variables (e.g. compressor discharge temperature, power consumption, required drying time, etc.) The system model was calibrated using experimental data on a prototype HPCD. In the paper, the modeling method is introduced, and the model predictions are compared with experimental data measured on a prototype HPCD.

    2015-05-01

    Full Text Available During pregnancy there is an evident change in the physical appearance of a woman's body. The most evident change is the substantial weight gain, increased abdominal region, torso and hip, and limbs thickening. Physical changes leads to the need of a wardrobe changing, especially in the fourth month of pregnancy. Given these factors the question arises is to identify the transformations of body conformation and ensure a maximum comfort in developing clothing products for this category. Because it is a continuous transformation, the products must be designed to be adjustable and versatile, ensuring their usability for a long period of the pregnancy and even after birth. The paper presents the specific algorithms for body conformations during pregnancy and the patterns designed based on these algorithms with the proper modifications. The principle of designing clothes for pregnant women refers to the introduction of pregnancy-related size changes in the standard method of pattern design. The research was conducted by INCDTP during the initial stage of a project, financed through national founds, consisting in a documentary study on morphologic indicators of women during the pregnancy period, the changes observe and their application in pattern design. Following the principles specific to the product group studied regarding comfort and style, INCDTP specialists have developed and produced a collection of clothing products for women during pregnancy. Key words: Pregnancy, algorithms, proportions, morphological indices, pattern design, clothing, changes

  8. Cotton bollworm resistance to Bt transgenic cotton: A case analysis

    Institute of Scientific and Technical Information of China (English)

    2010-01-01

    Cotton bollworm (Helicoverpa armigera) is one of the most serious insect pests of cotton. Transgenic cotton expressing Cry toxins derived from a soil bacterium, Bacillus thuringiensis (Bt), has been produced to target this pest. Bt cotton has been widely planted around the world, and this has resulted in efficient control of bollworm populations with reduced use of synthetic insecticides. However, evolution of resistance by this pest threatens the continued success of Bt cotton. To date, no field populations of bollworm have evolved significant levels of resistance; however, several laboratory-selected Cry-resistant strains of H. armigera have been obtained, which suggests that bollworm has the capacity to evolve resistance to Bt. The development of resistance to Bt is of great concern, and there is a vast body of research in this area aimed at ensuring the continued success of Bt cotton. Here, we review studies on the evolution of Bt resistance in H. armigera, focusing on the biochemical and molecular basis of Bt resistance. We also discuss resistance management strategies, and monitoring programs implemented in China, Australia, and India.

Gestalt Theory of the major psychological theories are used in how visual perception realizes and making sense of what is effective in this process. In perception stage brain tak es into account not only stimulus from eyes but also expectations arising from previous experience and interpreted the stimulus which are not exist in the real world as if they were there. Misperception interpretations that brain revealed are called as “Pe rception Illusion” or “Optical Illusion” in psychology. Optical illusion formats come into existence due to factors such as brightness, contrast, motion, geometry and perspective, interpretation of three - dimensional images, cognitive status and color. Opti cal illusions have impacts of different disciplines within the study area on people. Among the most important types of known optical illusion are Oppel - Kundt, Curvature - Hering, Helzholtz Sqaure, Hermann Grid, Muller - Lyler, Ebbinghaus and Ponzo illusion etc . In fact, all the optical illusions are known to be used in numerous area with various techniques and different product groups like architecture, fine arts, textiles and fashion design from of old. In recent years, optical illusion types are frequently us ed especially within the field of fashion design in the clothing model, in style, silhouette and fabrics. The aim of this study is to examine the clothing design applications where optical illusion is used and works done in this subject.

    Yasuda, Takeshi; Ijiri, Tokiko

    The clothing for cold weather were discused. The total insulation in man is made up of sum of the insulation afforded by clothes, air and tissues. A function of clothing is to protect the body from the environment, this is especially true when himalayan expedition. Many expedition to the himalayan high altitude have had useful experiences in the textile and clothing field. Historical development and fundamental matters of clothing for himalayan expedition were explained. The insulating properties of a fabric are due not to the fibers of the fabric itseif, but to the air trapped with in the fabric. it is impotant to realise that the thermal insulation of clothing is proportional to the thickness of the dead space air trapped within the clothing. Down clothes are extremely warm, light and comfortable. A windproof outer layer is necessary to prevent penetration by external air. If air penetrates, clothing the trapped dead air is moved and insu1ation will diminish. Overheating when exercising in the cold with loss of insulation associated with the production of sweat, and thus of darnp clothing, is a well recognized hazard. It was considered that we must make every effort to be as safe as possible in clothing science field for cold environment.

    2007-05-01

    Garment fit and resultant air volume is a crucial factor in thermal insulation, and yet, it has been difficult to quantify the air volume of clothing microclimate and relate it to the thermal insulation value just using the information on the size of clothing pattern without actual 3D volume measurement in wear condition. As earlier methods for the computation of air volume in clothing microclimate, vacuum over suit and circumference model have been used. However, these methods have inevitable disadvantages in terms of cost or accuracy due to the limitations of measurement equipment. In this paper, the phase-shifting moiré topography was introduced as one of the 3D scanning tools to measure the air volume of clothing microclimate quantitatively. The purpose of this research is to adopt a non-contact image scanning technology, phase-shifting moiré topography, to ascertain relationship between air volume and insulation value of layered clothing systems in wear situations where the 2D fabric creates new conditions in 3D spaces. The insulation of vests over shirts as a layered clothing system was measured with a thermal manikin in the environmental condition of 20 degrees C, 65% RH and air velocity of 0.79 m/s. As the pattern size increased, the insulation of the clothing system was increased. But beyond a certain limit, the insulation started to decrease due to convection and ventilation, which is more apparent when only the vest was worn over the torso of manikin. The relationship between clothing air volume and insulation was difficult to predict with a single vest due to the extreme openings which induced active ventilation. But when the vest was worn over the shirt, the effects of thickness of the fabrics on insulation were less pronounced compared with that of air volume. In conclusion, phase-shifting moiré topography was one of the efficient and accurate ways of quantifying air volume and its distribution across the clothing microclimate. It is also noted

    Full Text Available Abstract Background The use of clothing as a means of sun protection has been recommended in recent education campaigns. Contrary to popular opinion, however, some fabrics provide insufficient ultraviolet (UV protection. Material and methods We investigated 236 apparel textiles of the spring/summer collections 2000 and 2001. In accordance with the forthcoming European standard the UV protection factor (UPF of the fabrics was determined spectrophotometrically. Results Seventy-eight (33% fabrics had UPF 15 and 30 (30+. More than 70% of the wool, polyester, and fabric blends, and only less than 30% of the cotton, linen, and viscose fabrics had UPF values of 30+. Fabrics with black, navy-blue, white, green, or beige colours provided most frequently UPF values of 30+. Conclusions It is difficult for the sun-aware consumer to choose the 'right' garment, with a third of summer clothing providing insufficient UV protection and only half of the fabrics having UPF 30+, the UPF recommended by the European standard. Therefore, apparel summer fabrics should be measured and labelled in accordance with a standard document.

    Wildfire firefighting is an extremely demanding occupation performed under hot environment. The use of personal protective clothing (PPC) is needed to protect subjects from the thermal exposure. However, the additional use of PPC may increase the wildland firefighters' physiological strain, and consequently limit their performance. The aim of this study was to analyze the effect of four different PPC on the physiological strain of wildland firefighters under moderate conditions (30°C and 30% RH). Eight active and healthy wildland firefighters performed a submaximal walking test wearing a traditional short sports gear and 4 different PPC. The materials combination (viscose, Nomex, Kevlar, P-140 and fire resistant cotton) used during the PPC manufacturing process was different. During all tests, to simulate a real scenario subjects wore a backpack pump (20 kg). Heart rate, respiratory gas exchange, gastrointestinal temperature, blood lactate concentration, perceived exertion and temperature and humidity underneath the PPC were recorded throughout tests. Additionally, parameters of heat balance were estimated. Wearing a PPC did not cause a significant increase in the subjects' physiological response. The gastrointestinal temperature increment, the relative humidity of the microclimate underneath the PPC, the sweat residue in PPC, the sweat efficiency, the dry heat exchange and the total clothing insulation were significantly affected according to the PPC fabric composition. These results suggest that the PPC composition affect the moisture management. This might be taken into account to increase the wildland firefighters' protection in real situations, when they have to work close to the flames. PMID:28894421

    Full Text Available When it is examined, it is obvious that clothing has had different phases from old periods up to now. People have created clothings in accordance with their civilization level and any nation has formed its own clothes according to its customs, rituals beliefs and life styles. By this forms, any nation has created its own clothings. While clothing has been formed by t he effect of natural environment, traditional clothing has been formed according to social features. In the formation of these clothings, natural environment has not had an direct effect; yet, they are evaluated in their geographical regions and vicinities , because there are the same sociological, psychological and historical formations. People living in Anatolia have tried to make their clothes much more ostentatious and useful. And they have displayed admirable ornamentations on their clothes. It is possi ble to see that on traditional clothings. Clothing which has a big importance differs from city to city and even from town to town. This study is done on the pupose of analysing, fixating and finding out the clothes whose usage disappear swiftly but exist only in weddings, chests and doweries with regards to reveal the clothing culture and the understanding of art which takes form on this culture in Tavas, Denizli. This study is done by the purpose of analysing the traditional Turkish woman clothings that are don (şalvar, göynek, üç etek, cepken, tel kırma(bürgü, krep, kuşak, peştamalin which belong to Tavas, Denizli region in terms of material, cut, sewing and ornamentation features; and providing evidence in the direction of science discipline.

    Full Text Available The aim of this study was to explore the effect of date palm fibre as backing on sound absorption using three types of perforation plates and porous layers. The predicted results were verified by measurements conducted in an impedance tube on normal incidence sound absorption of 30 and 50 mm-thick date palm fibre and backing that may have positive effect are elaborated in this study. It describes how the porous materials of date palm fibre absorber panel can change the absorption behavior. The results obtained show that perforation plate, porous layers have a significant effect on absorption, whereas thickness panel have considerable effect too. This further indicate that three types have been used and also supported can be powerfully exploited to improve the absorption of date palm fibre and at the same time a reasonable thickness chosen, would be very efficient for absorption sound. An example is presented to show the approaches of enhancing the absorption, by utilizing the advantage of modification in the absorption sound. It exhibits that properly chosen perforation ratio along with suitable sample thickness can increase the absorption as well as the selected porous layers. It was evident that these can be powerfully exploited to improve the absorption of date palm fibre. Three types of perforation plate, porous layers were used to improve acoustic properties of date palm fibre. This means the innovative fibre becomes more active and efficient, plus it is renewable, waste material and very light compared to industrial substances.

    The objective of this work is to develop a 1-D transient heat and mass transfer model of a walking clothed human to predict the dynamic clothing dry heat insulation values and vapor resistances. Developing an integrated model of human and clothing system under periodic ventilation requires estimation of the heat and mass transfer film coefficients at the skin to the air layer subject to oscillating normal flow. Experiments were conducted in an environmental chamber under controlled conditions of 25 C and 50% relative humidity to measure the mass transfer coefficient at the skin to the air layer separating the wet skin and the fabric. A 1-D mathematical model is developed to simulate the dynamic thermal behavior of clothing and its interaction with the human thermoregulation system under walking conditions. A modification of Gagge's two-node model is used to simulate the human physiological regulatory responses. The human model is coupled to a clothing three-node model of the fabric that takes into consideration the adsorption of water vapor in the fibers during the periodic ventilation of the fabric by the air motion in from ambient environment and out from the air layer adjacent to the moist skin. When physical activity and ambient conditions are specified, the integrated model of human-clothing can predict the thermo-regulatory responses of the body together with the temperature and insulation values of the fabric. The developed model is used to predict the periodic ventilation flow rate in and out of the fabric, the periodic fabric regain, the fabric temperature, the air layer temperature, the heat loss or gain from the skin, and dry and vapor resistances of the clothing. The heat loss from the skin increases with the increase of the frequency of ventilation and with the increased metabolic rate of the body. In addition, the dry resistance of the clothing fabrics, predicted by the current model, IS compared with published experimental data. The current

    The Chaussez Capote Project interviewed 48 youths in Abidjan and Dabou aged 14-25 years on how to best get individuals in their age group to use condoms. 251 individuals aged 15-25 were also surveyed in Abidjan on the same subject. While more than 80% of this latter group had already discussed AIDS, sexually transmitted disease (STD), and prevention with others, 90% still wanted advice on these themes from medical staff and the media. 40% who had already used condoms did so incorrectly, while approximately 33% had experienced condom breakage during use. Respondents felt that condom promotion should be associated with information on AIDS, STDs, and contraception or information on general health. In response to this feedback, the project commissioned the creation of a promotional music cassette with French and African songs of different musical styles. Lyrics imparted technical information and correct misconceptions related to condom use. Free distribution of the cassette commenced August 1992, and approximately 800 were given to organizations and businesses. The cassette also aired on radio and Ivorian television, but met with only limited success. It is thought that its impact was limited due to the small number of copies duplicated and inefficient distribution. A new version was therefore created with different songs and short messages by popular African singers for local duplication and sale at a subsidized price starting December 1993. As a 2nd intervention, clothing metaphors applied to condoms and condom use were applied to the development of a clothing promotion loincloth designed Spring 1993. The cloth was pretested and revised to ultimately consist of panels depicting 2 young couples, a condom, a panther, and the words Entre nous. The cloth has been ordered for use by the National AIDS Committee, a condom social marketing project, and the French agency for development cooperation.

Cardiovascular exercise was chosen as the activity in this experiment for its profuse sweating effect and because it is considered a more severe treatment applied to the clothes than every-day usage. Study garments were exercise T-shirts and shorts purchased from various vendors. Fabric construction, fabric composition, and finishing treatment were defined as the key variables. The study was divided into three balanced experiments: a cotton-polyester-wool (CPW) T-shirts study with 61 participants, a polyester-modacrylic-polyester/cocona (PMC) T-shirts study with 40 participants, and a shorts study with 70 participants. In the CPW study, the T-shirts were made of 100% cotton, or of 100% polyester or of 100% wool, and categorized into open and tight knit constructions. In the PMC study, the T-shirts were made of 100% polyester, or of 82% modacrylic, or of 95% polyester with 5% cocona fiber, without construction distinction. The shorts were made either of 100% cotton or of 100% polyester, and were knitted or woven. Some garments were treated with Bio-Protect 500 antimicrobial finish according to the experimental design. The data collected from the questionnaire included garment identification, level of exertion, duration of exercise session, number of exercise sessions, an ordinal preference scale for nine sensory elements, and reason for retiring a used garment. From the analysis of the combined CPW and PMC shirt studies, there are statistically significant differences among the mean lifetimes of various types of shirts. The exercise shirts with the longest mean lifetimes are untreated wool (600 minutes), treated cotton (526 minutes), and untreated modacrylic (515 minutes). From the combined CPW and PMC shirt studies, the most preferred material was untreated open-knit wool, which is one of the two materials that jointly were worn the longest, untreated wool, both open-knit and tight-knit.

    2010-01-01

    Soldiers can wear chemical, biological, radiological and nuclear (CBRN) protective clothing to be protected against warfare agents. The disadvantage of that clothing is that higher protection introduces higher physiological burden. Therefore an optimum between comfort and protection must be found. Models of all relevant processes were created to find this optimum. The airflow profile around a cylinder with clothing-representing a dressed human body part-was modelled. This flow profile was used for calculating the agent vapour breakthrough through the clothing and for calculating the deposition of agents onto the skin (as indicators for protection). The flow profile was also used for calculating the temperature profile around the body part and the relative humidity underneath and in the clothing (as representative for physiological burden). As a result a tool was created, which can be used to identify the optimum properties of CBRN protective clothing, depending on the intended mission of the soldiers.

    Full Text Available Clothes which are used as military clothes are different from the other clothes, because they areworn continuously and long time. Heat, humidity and air movements are very important for these clothesbecause these parameters effect the thermophysiological comfort properties of clothes. These clothes mustallow the passage of water vapour from the body of the garment to feel comfortable to wearer. In thisstudy, moisture management properties of different blends of wool/polyester fabrics which are used inwinter military clothes were examined with MMT test device. For this aim, wetting time, absorption rate,spreading speed, accumulative one way transfer index and overall moisture management capacity offabrics, which have different wool/polyester blend ratio and weave pattern, were investigated. Also fabricpattern which are more appropriate for moisture transfer, were determined.

    The simulation of cloth with rich folds and wrinkles is a computationally expensive process. In this paper, we introduce an example-based algorithm for fast animation of plausible cloth wrinkles. Our algorithm does not depend on a character's pose, therefore it is valid for loose dresses, curtains, etc., not just cloth defined by skinning techniques. Central to our approach is a correspondence between low and high-resolution cloth deformations, both at the training and synthesis stages. Based on this correspondence, we define an algorithm for synthesizing cloth wrinkles as a function of the deformation of a low-resolution cloth and a set of example poses. We demonstrate the animation of plausible high-resolution wrinkles at high frame rates, suitable for interactive applications such as video games.

    This work has shown is that it is possible to recycle continuous and short fibre reinforced thermosetting resins while keeping almost the whole of the original material, both fibres and matrix, within the recyclate. By splitting, crushing hot or cold, and hot forming, it is possible to create a recyclable material, which we designate a Remat, which can then be used to remanufacture other shapes, examples of plates and tubes being demonstrated. Not only can remanufacturing be done, but it has been shown that over 50 % of the original mechanical properties, such as the E modulus, tensile strength, and interlaminar shear strength, can be retained. Four different forms of composite were investigated, a random mat Glass Fibre Reinforced Plastic (GFRP) bathroom component and boat hull, woven glass and carbon fibre cloth impregnated with an epoxy resin, and unidirectional carbon fibre pre-preg. One of the main factors found to affect composite recyclability was the type of resin matrix used in the composite. Thermoset resins tested were shown to have a temperature range around the Glass Transition Temperature (Tg) where they exhibit ductile behaviour, hence aiding reforming of the material. The high-grade carbon fibre prepreg was found to be less easy to recycle than the woven of random fibre laminates. One method of remanufacturing was by heating the Remat to above its glass transition temperature, bending it to shape, and then cooling it. However, unless precautions are taken, the geometric form may revert. This does not happen with the crushed material.

    2015-06-01

    The raw cotton production requires multiple steps being one of them the removal of impurities acquired during previous processes. This procedure is widely used by textile industries around the world and is called bleaching. The raw cotton is composed by cellulosic and non-cellulosic materials like waxes, pectins and oils, which are responsible for its characteristic yellowish color. The bleaching process aims to remove the non-cellulosic materials concentration in the fabric, increasing its whiteness degree. The most used bleaching method utilizes a bath in an alkali solution of hydrogen peroxide, stabilizers and buffer solutions under high temperature. In the present study we evaluated the possibility of using a blue illumination for the bleaching process. We used blue LEDs (450 nm) to illuminate an acid hydrogen peroxide solution at room temperature. The samples treated by this method were compared with the conventional bleaching process through a colorimetric analysis and by a multiple comparison visual inspection by volunteers. The samples were also studied by a tensile test in order to verify the integrity of the cloth after bleaching. The results of fabric visual inspection and colorimetric analysis showed a small advantage for the sample treated by the standard method. The tensile test showed an increasing on the yield strength of the cloth after blue light bleaching. The presented method has great applicability potential due to the similar results compared to the standard method, with relative low cost and reduced production of chemical waste.

    Thermoregulatory responses were compared under two experimental conditions, in the laboratory (Experiment I), and in the field (Experiment II), between two kinds of protective clothing for spraying pesticides. One was currently being used (Type A), and was composed of ready made Gore-Tex clothing, mask, polyurethane gloves and rubber boots. The other one was newly designed (Type B), and was composed of pesticide-proof clothing (100% cotton with water repellent finish), mask, Gore-Tex gloves, and special boots consisting of rubber for the feet and ankle and Gore-Tex around the legs. In addition, the head and chest were cooled by frozen gel strips fixed in the cap and undershirt. In Experiment I, five female adults took part, in a climate-chamber controlled at an ambient temperature of 28 degrees C and a relative humidity of 60%. In Experiment II, five farmers (one male and four female) were tested in an apple orchard in July, August and September. The main results are summarized as follows: (1) change of rectal temperature was inhibited more effectively in Type B in Experiment I, (2) change of heart rate tended to be lower in Type B than in Type A in both experiments, (3) salivary lactic acid concentration at the end of the first exercise was significantly higher in Type A than in Type B in Experiment I, (4) the number of contractions in the handgrip exercise which was performed immediately after the third exercise, was significantly smaller in Type A than in Type B in Experiment I, (5) subjective comfort sensation was significantly improved in Type B in Experiments I and II. Thus, it was concluded that the newly designed protective clothing could reduce thermal stress during the spraying of pesticides in an apple orchard in summer.

  16. Estimating Clothing Thermal Insulation Using an Infrared Camera

    Directory of Open Access Journals (Sweden)

    Jeong-Hoon Lee

    2016-03-01

    Full Text Available In this paper, a novel algorithm for estimating clothing insulation is proposed to assess thermal comfort, based on the non-contact and real-time measurements of the face and clothing temperatures by an infrared camera. The proposed method can accurately measure the clothing insulation of various garments under different clothing fit and sitting postures. The proposed estimation method is investigated to be effective to measure its clothing insulation significantly in different seasonal clothing conditions using a paired t-test in 99% confidence interval. Temperatures simulated with the proposed estimated insulation value show closer to the values of actual temperature than those with individual clothing insulation values. Upper clothing’s temperature is more accurate within 3% error and lower clothing’s temperature is more accurate by 3.7%~6.2% error in indoor working scenarios. The proposed algorithm can reflect the effect of air layer which makes insulation different in the calculation to estimate clothing insulation using the temperature of the face and clothing. In future, the proposed method is expected to be applied to evaluate the customized passenger comfort effectively.

    2003-01-01

    Today, clothing and clothing systems for cleanrooms are mainly tested with regard to material properties such as particle generation, particle filtration, and resistance to wear. The dispersal chamber or "body-box" has been used for studying the protective efficacy of clothing systems in use, for example by Hoborn in 1981 (1) and Whyte and Bailey in 1985. A modified dispersal chamber has recently been installed at KTH. Tests and comparative studies have been performed in the dispersal chamber on selected clothing systems. The latest tests have been performed in two parts. In Part 1, each person performed 12 sequences dressed in new, modern cleanroom clothing systems with small variations, such as with and without goggles, different face masks, and different sizes of hoods. In Part 2, each person performed six test sequences with new, modern cleanroom clothing systems with variations in fabrics, and as a comparison, two sequences with pharmaceutical clothing system and surgical clothing system, respectively. The results are given in total number of airborne particles (> or = 0.5 microm per cubic meter) and airborne aerobic CFU per cubic meter. Statistical evaluations of the results have been performed. The source strengths of the contamination source people wearing modern cleanroom clothing systems have been estimated.

    Cutinase from Thermobifida fusca was used to esterify the hydroxyl groups of cellulose with the fatty acids from triolein. Cutinase and triolein were pre-adsorbed on cotton and the reaction proceeded in a dry state during 48 h at 35°C. The cutinase-catalyzed esterification of the surface of cotton fabric resulted in the linkage of the oleate groups to the glycoside units of cotton cellulose. The superficial modification was confirmed by performing ATR-FTIR on treated cotton samples and by MALDI-TOF analysis of the liquors from the treatment of the esterified cotton with a crude cellulase mixture. Modified cotton fabric also showed a significant increase of hydrophobicity. This work proposes a novel bio-based approach to obtain hydrophobic cotton.

    Shukla, Rajesh Prasad; Parihar, Niraj Singh

    2016-09-01

    This work presents the results of laboratory tests conducted on black cotton soil mixed with micro-fine slag. Different proportions of micro-fine slag, i.e., 3, 6, 9, 12 and 15 % were mixed with the black cotton soil to improve soil characteristics. The improvement in the characteristics of stabilized soil was assessed by evaluating the changes in the physical and strength parameters of the soil, namely, the Atterberg limits, free swell, the California Bearing Ratio (CBR), compaction parameters and Unconfined Compressive Strength (UCS). The mixing of micro-fine slag decreases the liquid limit, plasticity index and Optimum Moisture Contents (OMC) of the soil. Micro-fine slag significantly increases the plastic limit, UCS and CBR of the soil up to 6-7 % mixing, but mixing of more slag led to decrease in the UCS and CBR of the soil. The unsoaked CBR increased by a substantial amount unlike soaked CBR value. The swell potential of the soil is reduced from medium to very low. The optimum amount of micro-fine slag is found to be approximately 6-7 % by the weight of the soil.

    Personal protective clothing (PPC) shields firefighters from thermal and other occupational hazards; however, it also contributes to physiological and perceptual strain. This study examined the effect of clothing layers worn under structural fire fighting turnout gear (TOG) on physiological and perceptual responses during alternating work/recovery cycles and assessed the clothing ensembles' (PPC + base layer) material performance. Values are reported as mean ± standard error of the mean. Ten men (age, 21 ± 0.3 yr; height, 1.74 ± 0.02 m; weight, 74.3 ± 2.3 kg; VO2max, 58.9 ± 2.0 mL/kg/min) completed a 110-min alternating work/recovery walking protocol (three 20-min exercise bouts/10-, 20-, and 20-min recovery sessions) in a thermo-neutral (21.0°C, 58.7% RH) laboratory while wearing a cotton t-shirt (COT) or COT and a station uniform (SU) shirt under fire fighting TOG (COT+TOG and COT+SU+TOG, respectively). Changes in heart rate (HR), core temperature (Tco), skin temperature (Tsk), rating of perceived exertion (RPE), and thermal sensations (TS) were compared across exercise and recovery periods. During exercise sessions, HR, Tco, Tsk, and RPE reached similar levels for COT+TOG and COT+SU+TOG. During Recoveries 1, 2, and 3, mean chest Tsk decreased by 3.96, 6.64, and 6.49°C, respectively, for COT+TOG compared with 2.24, 3.78, and 4.09°C for COT+SU+TOG (p benefits were experienced during the recovery sessions for the COT+TOG ensemble as evidenced by a lower chest Tsk. In addition, materials performance testing revealed COT+SU+TOG provided greater thermal protection (64.8 ± 1.9 vs. 56.4 ± 0.3 cal/cm(2); p < 0.05) and equivalent heat dissipation compared with COT+TOG. These findings could guide departmental decisions about the use of station shirts.

    This program covered the development of two separate products; an electric heat pump clothes dryer and a modulating gas dryer. These development efforts were independent of one another and are presented in this report in two separate volumes. Volume 1 details the Heat Pump Dryer Development while Volume 2 details the Modulating Gas Dryer Development. In both product development efforts, the intent was to develop high efficiency, high performance designs that would be attractive to US consumers. Working with Whirlpool Corporation as our commercial partner, TIAX applied this approach of satisfying consumer needs throughout the Product Development Process for both dryer designs. Heat pump clothes dryers have been in existence for years, especially in Europe, but have not been able to penetrate the market. This has been especially true in the US market where no volume production heat pump dryers are available. The issue has typically been around two key areas: cost and performance. Cost is a given in that a heat pump clothes dryer has numerous additional components associated with it. While heat pump dryers have been able to achieve significant energy savings compared to standard electric resistance dryers (over 50% in some cases), designs to date have been hampered by excessively long dry times, a major market driver in the US. The development work done on the heat pump dryer over the course of this program led to a demonstration dryer that delivered the following performance characteristics: (1) 40-50% energy savings on large loads with 35 F lower fabric temperatures and similar dry times; (2) 10-30 F reduction in fabric temperature for delicate loads with up to 50% energy savings and 30-40% time savings; (3) Improved fabric temperature uniformity; and (4) Robust performance across a range of vent restrictions. For the gas dryer development, the concept developed was one of modulating the gas flow to the dryer throughout the dry cycle. Through heat modulation in a

This has been especially true in the US market where no volume production heat pump dryers are available. The issue has typically been around two key areas: cost and performance. Cost is a given in that a heat pump clothes dryer has numerous additional components associated with it. While heat pump dryers have been able to achieve significant energy savings compared to standard electric resistance dryers (over 50% in some cases), designs to date have been hampered by excessively long dry times, a major market driver in the US. The development work done on the heat pump dryer over the course of this program led to a demonstration dryer that delivered the following performance characteristics: (1) 40-50% energy savings on large loads with 35 F lower fabric temperatures and similar dry times; (2) 10-30 F reduction in fabric temperature for delicate loads with up to 50% energy savings and 30-40% time savings; (3) Improved fabric temperature uniformity; and (4) Robust performance across a range of vent restrictions. For the gas dryer development, the concept developed was one of modulating the gas flow to the dryer throughout the dry cycle. Through heat modulation in a

    Only simple equipment, simple technology and low initial capital investment are needed in their manufacture. The condoms can be made by people who were previously unskilled or only semi-skilled workers. Plastic condoms differ from those made of latex rubber in that the nature of the plastic film allows unlimited shelf-life. Also, the plastic has a higher degree of lubricity than latex rubber; if there is a demand for extra lubrication in a particular market, this can be provided. Because the plastic is inert, these condoms need not be packaged in hermetically sealed containers. All these attributes make it possible to put these condoms on the distributors' shelves in developing countries competitively with rubber condoms. The shape of the plastic condom is based on that of the lamb caecum, which has long been used as luxury-type condom. The plastic condom is made from plastic film (ethylene ethyl acrilate) of 0.001 inch (0.0254 mm.) thickness. In addition, a rubber ring is provided and sealed into the base of the condom for retention during coitus. The advantage of the plastic condom design and the equipment on which it is made is that production can be carried out either in labour-intensive economy or with varying degrees of mechanization and automation. The uniform, finished condom if made using previously untrained workers. Training of workers can be done in a matter of hours on the two machines which are needed to produce and test the condoms. The plastic film is provided on a double wound roll, and condom blanks are prepared by means of a heat-sealing die on the stamping machine. The rubber rings are united to the condom blanks on an assembly machine, which consists of a mandrel and heat-sealing equipment to seal the rubber ring to the base of the condom. Built into the assembly machine is a simple air-testing apparatus that can detect the smallest pinhole flaw in a condom. The manufacturing process is completed by unravelling the condom from the assembly

    Advances in plant genomics have had an impact on the field of forensic botany. However, the use of pollen DNA profiling in forensic investigations has yet to be applied. Five volunteers wore a jacket with Pinus echinata pollen-containing cotton swatches for a 14-day period. Pollen decay was evaluated at days 0, 3, 6, 9 and 14 by microscopy. Pollen grains were then transferred to slides using a portable forensic vacuum handle. Ten single grains per swatch were isolated for DNA analysis. DNA was extracted using a high throughput extraction method. A nine-locus short tandem repeat (STR) multiplex system, including previously published primers from Pinus taeda, was developed. DNA was amplified by PCR using fluorescent dyes and analyzed by capillary electrophoresis. Pollen counts from cotton swatches in a 14-day period exhibited an exponential decay from 100% to 17%. The success rate of PCR amplification was 81.2%. Complete and partial STR profiles were generated from 250 pollen grains analyzed (44% and 37%, respectively). Due to the limited amount of DNA, drop-in events were observed (1.87%). However, the rate of contamination with pollen from other pine individuals originating from environmental sources was 4.4%. In conclusion, this study has shown that pollen can be a stable source of forensic DNA evidence, as a proof-of-principle, and that may persist on cotton clothing for at least 14 days of wear. This method can be applied in forensic cases where pollen grains larger than 10 μm (e.g., from herbs or trees) may be transferred to clothing (worn by suspect or victim) by primary contact.

    Two kinds of humidity-induced, bendable smart clothing have been designed to reversibly adapt their thermal insulation functionality. The first design mimics the pores in human skin, in which pre-cut flaps open to produce pores in Nafion sheets when humidity increases, as might occur during human sweating thus permitting air flow and reducing both the humidity level and the apparent temperature. Like the smart human sweating pores, the flaps can close automatically after the perspiration to keep the wearer warm. The second design involves thickness adjustable clothes by inserting the bent polymer sheets between two fabrics. As the humidity increases, the sheets become thinner, thus reducing the gap between the two fabrics to reduce the thermal insulation. The insulation layer can recover its original thickness upon humidity reduction to restore its warmth-preservation function. Such humidity sensitive smart polymer materials can be utilized to adjust personal comfort, and be effective in reducing energy consumption for building heating or cooling with numerous smart design.

Efficiency in assembly lines has an important role on cost and quality which are the basic fundamentals of competition. Assembly lines contain a number of workstations and tasks (jobs are processed in these stations and are moved from station to station. The tasks are assigned to each station regarding a cycle time. The cycle time is the maximum available time for the production of a job at any workstation. The assingning of jobs to workstations is based on the objective of minimizing the workflow among the workstations, reducing the throughput time as well as the work in progress and thus increasing productivity. If the jobs are not allocated in balance, this will cause idle workstations and waste of workforce besides the loss of overall efficiency. In this study, an assebly line balancing problem was examined for a five pocket denim trousers in a clothing company. Firstly, priority associations and standard durations of operations of denim trousers were determined. Then, assembly line balancing study was carried out by using ranked positional weights assembly line balancing method developed by Helgeson and Birnie to increase the production in a clothing company manufacturing five pocket denim trousers.

    It is unknown whether allowing patients to have BMD (bone mineral density) studies acquired while wearing radiolucent clothing adlib contributes appreciably to the measurement error seen. To examine this question, a spine phantom was scanned 30 times without any clothing, while draped with a gown, and while draped with heavy winter clothing. The effect on mean BMD and on SD (standard deviation) was assessed. The effect of clothing on mean or SD of the area was not significant. The effect of clothing on mean and SD for BMD was small but significant and was around 1.6% for the mean. However, the effect on BMD precision was much more clinically important. Without clothing the spine phantom had an least significant change of 0.0077 gm/cm(2), while when introducing variability of clothing the least significant change rose as high as 0.0305 gm/cm(2). We conclude that, adding clothing to the spine phantom had a small but statistically significant effect on the mean BMD and on variance of the measurement. It is unlikely that the effect on mean BMD has any clinical significance, but the effect on the reproducibility (precision) of the result is likely clinically significant.

    2005-01-01

    An E6 gene from sea island cotton (Gossypium barbadense) was expressed specifically in cotton fiber cells to transfer functions to cultivated species for better transgenic engineering. The regulatory activity of the E6 promoter region was then studied by isolating a 614-bp fragment of the 5'-flanking region from upland cotton (Gossypium hirsutum CRI-12) to produce a green fluorescent protein (GFP) reporter construct for analysis of tissue-specific expression in transgenic tobacco seedlings. Fluorescent analyses indicate that the relatively short E6 promoter is sufficient to direct green fluorescent protein expression specifically in the leaf trichomes (hair cells) of the transgenic tobacco plants. As cotton fibers are also unicellular trichomes that differentiate from epidermal cells of developing cotton ovules, the result suggests that the relatively short E6 promoter can serve as a fiber-specific expression promoter for genetic engineering to improve cotton fiber quality.

    The ASTM F2370 (2010) is the only standard with regard to measurement of clothing real evaporative resistance by means of a sweating manikin. However, the sweating set-point is not recommended in the standard. In this study, the effect of sweating rate on clothing real evaporative resistance was investigated on a 34-zone "Newton" sweating thermal manikin in a so-called isothermal condition (T manikin = T a = T r). Four different sweating set rates (i.e., all segments had a sweating rate of 400, 800, 1200 ml/hr ∙ m(2), respectively, and different sweating rates were assigned to different segments) were applied to determine the clothing real evaporative resistance of five clothing ensembles and the boundary air layer. The results indicated that the sweating rate did not affect the real evaporative resistance of clothing ensembles with the absence of strong moisture absorbent layers. For the clothing ensemble with tight cotton underwear, a sweating rate of lower than 400 ml/hr ∙ m(2) is not recommended. This is mainly because the wet fabric "skin" might not be fully saturated and thus led to a lower evaporative heat loss and thereby a higher real evaporative resistance. For vapor permeable clothing, the real evaporative resistance determined in the so-called isothermal condition should be corrected before being used in thermal comfort or heat strain models. However, the reduction of wet thermal insulation due to moisture absorption in different test scenarios had a limited contribution to the effect of sweating rate on the real evaporative resistance.

    Wearable electronics offer the combined advantages of both electronics and fabrics. In this article, we report the fabrication of wearable supercapacitors using cotton fabric as an essential component. Carbon nanotubes are conformally coated onto the cotton fibers, leading to a highly electrically conductive interconnecting network. The porous carbon nanotube coating functions as both active material and current collector in the supercapacitor. Aqueous lithium sulfate is used as the electrolyte in the devices, because it presents no safety concerns for human use. The supercapacitor shows high specific capacitance (~70-80 F·g-1 at 0.1 A·g-1) and cycling stability (negligible decay after 35,000 cycles). The extremely simple design and fabrication process make it applicable for providing power in practical electronic devices. © 2010 Tsinghua University Press and Springer-Verlag Berlin Heidelberg.

A prototype system was designed from off-the-shelf components that can meet the project’s efficiency goals and are affordable. An experimental prototype system was built based on the design that reached 50% energy savings. Improvements have been identified that will reduce drying times of over 60 minutes to reach the goal of 40 minutes. Nevertheless, the prototype represents a step change in efficiency over heat pump dryers recently introduced to the U.S. market, with 30% improvement in energy efficiency at comparable drying times.

    Herein, we demonstrate that a flexible, air-permeable, thermoelectric (TE) power generator can be prepared by applying a TE polymer (e.g. poly(3,4-ethylenedioxythiophene):poly(4-styrenesulfonate)) coated commercial fabric and subsequently by linking the coated strips with a conductive connection (e.g. using fine metal wires). The poly(3,4-ethylenedioxythiophene):poly(4-styrenesulfonate) coated fabric shows very stable TE properties from 300 K to 390 K. The fabric device can generate a TE voltage output (V) of 4.3 mV at a temperature difference (ΔT) of 75.2 K. The potential for using fabric TE devices to harvest body temperature energy has been discussed. Fabric-based TE devices may be useful for the development of new power generating clothing and self-powered wearable electronics.

  10. Bern clothes washer study. Final report

    1998-03-01

    The US market for domestic clothes washers is currently dominated by conventional, vertical axis washers, which typically require about 40 gallons of water for each load. Although small for an individual load, the fact that 35 billion loads of laundry are washed annually in the US results in a substantial quantity of water and energy use. Although much smaller, today`s market for high-efficiency clothes washers which use much less water and energy is growing albeit slowly as manufacturers are making washers based around tumble-action, horizontal axis designs available, information about their performance and benefits is being developed, and consumers are made aware of these benefits. To help build awareness of these benefits and to accelerate markets for high-efficiency washers, DOE, under its Energy Star Program and in cooperation with Maytag Appliances, conducted a field-evaluation of high-efficiency washers using Bern, Kansas (population approximately 200) as a test bed. Baseline washer performance data as well as customer washing behavior were obtained from data collected on the existing washers of more than 100 participants in this instrumented study. Following a 2-month initial study period, all conventional washers were replaced by high-efficiency, tumble action washers, and the experiment continued for another 3-month period. Based on measured data from over 20,000 loads of laundry, the impact of the washer replacement on (1) individual customers` energy and water consumption, (2) customers` laundry habits and perceptions, and (3) the community`s water supply and waste water systems were determined and reported.

    Full Text Available Plastic bronchitis, a rare but serious clinical condition, commonly seen after Fontan surgeries in children, may be a manifestation of suboptimal adaptation to the cavopulmonary circulation with unfavorable hemodynamics. They are ominous with poor prognosis. Sometimes, infection or airway reactivity may provoke cast bronchitis as a two-step insult on a vulnerable vascular bed. In such instances, aggressive management leads to longer survival. This report of cast bronchitis discusses its current understanding.

    A cloth simulation represents the behavior of cloth objects such as flag, tablecloth, or even garments has application in clothing animation for games and virtual shops. Elastically deformable models have widely used to provide realistic and efficient simulation, however problem of overstretching is encountered. We introduce a new cloth simulation algorithm that replaces iterative distance constraint enforcement steps with non-iterative ones for preventing over stretching in a spring-mass system for cloth modeling. Our method is based on a simple position correction procedure applied at one end of a spring. In our experiments, we developed a rectangle cloth model which is initially at a horizontal position with one point is fixed, and it is allowed to drape by its own weight. Our simulation is able to achieve a plausible cloth drapes as in reality. This paper aims to demonstrate the reliability of our approach to overcome overstretches while decreasing the computational cost of the constraint enforcement process due to an iterative procedure that is eliminated.

    Wearing behavior and thermoregulatory responses of five young women (YG; 20 +/- 1 yr) and five aged women (AG; 65 +/- 3 yr) to indoor cold in summer were investigated in this study. The subjects were exposed to 21.0 +/- 0.5 degrees C and 55 +/- 5% RH while seated during a 90-minute experiment. The subjects were allowed to select and wear for thermal comfort clothing whenever they needed additional clothing during the experiment. Rectal temperature (Tre) and temperatures of 7 sites (head, chest, forearm, hand, thigh, leg, foot) of the skin of the subjects were measured every 10 minutes. Mean skin temperature (Tsk) of the subject was obtained every 10 minutes. First selection time of additional clothing was monitored and weight of selected total clothing was calculated. The results for this study were as follows: Tre and Tsk gradually decreased in YG and AG, however Tre decreased less than Tsk which decreased greater in AG than YG (p clothing and thermal sensation response were slower than YG's. Furthermore, total clothing weight was less in AG than YG. It was concluded that clothing selection behavior would modify the intrinsic thermoregulatory responses of the aged women to the cold stress in the summer.

    Developing effective conservation programs that positively impact the survival of a species while considering the needs of local communities is challenging. Here we present an overview of the conservation program developed by Proyecto Tití to integrate local communities in the conservation of Colombia's critically endangered primate, the cotton-top tamarin (Saguinus oedipus). Our comprehensive assessment of the threats effecting the long-term survival of the cotton-top tamarin allowed us to establish the primary components of our program. Proyecto Tití has three areas of emphasis: (1) scientific studies detailing the biology and long-term survival of the cotton-top tamarin, (2) conservation education programs to increase public awareness and conservation knowledge, and (3) community empowerment programs that demonstrate a valuable economic incentive to protecting wildlife and forested areas in Colombia. This integrated approach to conservation that involves local communities in activities that benefit individuals, as well as wildlife, has proven to be remarkably effective in protecting cotton-top tamarins and their forested habitat. Our bindes program, which uses small cook stoves made from clay, has demonstrated a marked reduction in the number of trees that have been harvested for firewood. Developing environmental entrepreneurs, who create products made from recycled plastic for sale in national and international markets, has had a significant impact in reducing the amount of plastic that has been littering the environment and threatening the health of wildlife, while creating a stable economic income for rural communities. Proyecto Tití has provided economic alternatives to local communities that have dramatically reduced the illegal capture of cotton-top tamarins and forest destruction in the region that has positively impacted the long-term survival of this critically endangered primate.

    Clothing manufacturers' direct investment and joint ventures in developing regions have seen to grow rapidly in the past few decades. Non-optimized selection can contribute to adverse effects affecting the performance of the plants on aspects of productivity, manufacturing and logistics cost. Selection of proper plant location is thus crucial. The conventional approaches to sites location are based on the factors and their weights. However, determining the weight of each factor is very difficult and time consuming. While the situation is changed, all the work must be redone again. This study aims to develop a decision-making system onclothing plant location for Hong Kong clothing manufacturer. The proposed system utilizes artificial neural network to study the relationship between the factors and the suitability index of candidate sites. Firstly, the factors are stratified using the fuzzy analytical hierarchy process (FAHP) by review the related references and interviewing the experts.Secondly, the corresponding data are collected from the experts by questionnaire and the related government publication. Finally, the feedforward neural network with error backpropagation(EBP) learning algorithm is trained and applied to make decision. The results show that the proposed system performs well and has the characteristic of adaptability and plasticity.

    This study evaluated the toxicity and duration of 3 residual insecticides against the Old World sand fly, Phlebotomus papatasi, an important vector of cutaneous leishmaniasis, on 2 types of tent material used by the US military in Afghanistan and the Middle East. Vinyl and cotton duck tent surfaces were treated at maximum labeled rates of lambda-cyhalothrin (Demand CS, Zeneca Inc, Wilmington, DE), bifenthrin (Talstar P Professional, FMC Corporation, Philadelphia, PA) and permethrin (Insect Repellent, Clothing Application, 40%), then subsequently stored in indoor, shaded spaces at room temperature (60%-70% relative humidity (RH), 22°C-25°C), and under sunlight and ambient air temperatures outdoors (20%-30% RH, 29°C-44°C). Insecticide susceptible colony flies (F110) obtained from the insectary of US Naval Medical Research Unit No. 3, Cairo, Egypt, were exposed to treated tent surfaces for 30-minute periods twice monthly for up to 5 months, then once monthly thereafter, using the World Health Organization cone assay. Lambda-cyhalothrin treated cotton duck tent material stored indoors killed P. papatasi for 8 months, while the complementary sun-exposed cotton duck material killed adult flies for 1 month before the efficacy dropped to less than 80%. Sand fly mortality on permethrin- and bifenthrin-treated cotton duck decreased below 80% after 2 weeks exposure to sunlight. Shade-stored permethrin and bifenthrin cotton duck material killed more than 80% of test flies through 5 months before mortality rates decreased substantially. Vinyl tent material provided limited control (less than 50% mortality) for less than 1 month with all treatment and storage regimes. Lambda-cyhalothrin-treated cotton duck tent material provided the longest control and produced the highest overall mortalities (100% for 8 months (shaded), more than 90% for 1 month (sunlight-exposed)) of both cotton duck and vinyl tents.

Unfortunately, this restriction cannot be satisfied in many situations and most preexisting video data does not adhere to it either. In this work we propose a graphics based vision approach for tracking humans markerlessly without making this assumption. Instead, a physically based simulation of the clothing the tracked person is wearing is used to guide the tracking algorithm.

  12. A Mathematical Modeling Framework for Analysis of Functional Clothing

    2007-11-01

    Full Text Available In the analysis and design of functional clothing systems, it is helpful to quantify the effects of a system on a wearer’s physical performance capabilities. Toward this end, a clothing modeling framework for quantifying the mechanical interactions between a given clothing system design and a specific wearer performing defined physical tasks is proposed. The modeling framework consists of three interacting modules: (1 a macroscale fabric mechanics/dynamics model; (2 a collision detection and contact correction module; and (3 a human motion module. In the proposed framework, the macroscopic fabric model is based on a rigorous large deformation continuum-degenerated shell theory representation. Material models that capture the stress-strain behavior of different clothing fabrics are used in the continuum shell framework. The collision and contact module enforces the impenetrability constraint between the fabric and human body and computes the associated contact forces between the two. The human body is represented in the current framework as an assemblage of overlapping ellipsoids that undergo rigid body motions consistent with human motions while performing actions such as walking, running, or jumping. The transient rigid body motions of each ellipsoidal body segment in time are determined using motion capture technology. The integrated modeling framework is then exercised to quantify the resistance that the clothing exerts on the wearer during the specific activities under consideration. Current results from the framework are presented and its intended applications are discussed along with some of the key challenges remaining in clothing system modeling.

    Full Text Available Crop recovery of applied Phosphorus (P fertilizer can be low, especially during season of low soil temperature, which decreases plant root growth and nutrient uptake. The H2PO4- or HPO4-2 anions readily react with soil cations such as Calcium (Ca, Magnesium (Mg, iron (Fe and Aluminum (Al to produce various phosphate compounds of very limited water solubility. Specialty Fertilizer Products (SFP, Leawood, KS, USA has developed and patented a product registered as AVAIL® that is reported to attract and sequester antagonistic cations out of the soil solution leaving more of applied P in available form for plant uptake. To evaluate effectiveness of AVAIL product for cotton production, experiments were conducted in two locations in West Tennessee, Grand Junction (GJ in Hardeman County and Ames Plantation (AP located in Fayette County. Treatments consisted of applying Mono-Ammonium Phosphate (MAP, 11-52-0 alone or coated with AVAIL at rates of 34 or 68 kg ha-1 P2O5. A no P check was also included. An additional treatment consisting of AVAIL treated P in combination with Nutrisphere-N®, a Nitrogen (N stabilizer product offered by SFP, was also included. At GJ site, when averaged over P rates and years, AVAIL treated MAP improved tissue P concentration and increased cotton lint yield by 157 kg ha-1 over untreated MAP. At AP site, when averaged over years and P rates, application of AVAIL treated MAP increased cotton lint yield by 85 kg ha-1 over untreated MAP. In both experiments, 34 kg ha-1 AVAIL treated MAP produced higher tissue P concentrations and greater yields than 68 kg ha-1 without AVAIL. Influencing reactions in the micro-environment around the fertilizer granule has proven to have a significant benefit on the yield and P uptake of cotton. More research is needed to determine P content in the soil and further

    To understand the influences of actual sampling conditions on cotton fiber length testing, this article presents a theoretic study on the distributions and fibrogram of the sample taken out by sampler from ideal sliver at a certain angle. From the distributions expression it can be found that the size of the sampler and the sampling angle are important factors which affect sampling, but if the sampling width is narrow enough, the influence of the sampling angle on the distributions and fibrogram is small enough to be omitted. This is an important conclusion for sampling, in light of this, some suggestions for designing new type sampler are put forward.

    Transgenic cotton is among the first transgenic plants commercially adopted around the world. Since it was first introduced into the field in the middle of 1990s, transgenic cotton has been quickly adopted by cotton farmers in many developed and developing countries. Transgenic cotton has offered many important environmental, social, and economic benefits, including reduced usage of pesticides, indirect increase of yield, minimizing environmental pollution, and reducing labor and cost. Agrobacterium-mediated genetic transformation method is the major method for obtaining transgenic cotton. However, pollen tube pathway-mediated method is also used, particularly by scientists in China, to breed commercial transgenic cotton. Although transgenic cotton plants with disease-resistance, abiotic stress tolerance, and improved fiber quality have been developed in the past decades, insect-resistant and herbicide-tolerant cotton are the two dominant transgenic cottons in the transgenic cotton market.

    Ramie cloth/UP resin composite was formed at 0.2 MPa and cured at room temperature for 24 h and treated at 80 ℃ for2 h. The physical and mechanical properties of the composites with different volume fractions of ramie cloth were studied. The results show that,with the increase of the volume fraction of the ramie cloth,densities of the composites become greater and greater,though all lower than the theoretical values,the linear shrinkage during the formation decreases from 1.20% of the original UP resin to 0.18% of the composite with 30% of ramie cloth in volume,all the composites also absorb more water than UP resin casting,greater volume fraction of the fiber,more water will be absorbed,but the increase in water absorption becomes smaller and smaller with time. As regards some mechanical properties,the tensile strength,flexural strength,flexural modulus and impact strength are all improved when more ramie fiber is added. Compared with those of pure UP resin casting,the mechanical properties are increased by 93.93%,76.20%,190.18% and 227.26% respectively when the volume fraction of the ramie cloth in the composite is 30%. The differential scanning calorimetry results show that only one peak will appear for the sample without or with less ramie fiber while two peaks will appear when more ramie cloth is added.

    2013-08-01

    Full Text Available Most species evolve within fluctuating environments, and have developed adaptations to meet the challenges posed by environmental heterogeneity. One such adaptation is phenotypic plasticity, or the ability of a single genotype to produce multiple environmentally-induced phenotypes. Yet, not all plasticity is adaptive. Despite the renewed interest in adaptive phenotypic plasticity and its consequences for evolution, much less is known about maladaptive plasticity. However, maladaptive plasticity is likely an important driver of phenotypic similarity among populations living in different environments. This paper traces four strategies for overcoming maladaptive plasticity that result in phenotypic similarity, two of which involve genetic changes (standing genetic variation, genetic compensation and two of which do not (standing epigenetic variation, plastic compensation. Plastic compensation is defined as adaptive plasticity overcoming maladaptive plasticity. In particular, plastic compensation may increase the likelihood of genetic compensation by facilitating population persistence. We provide key terms to disentangle these aspects of phenotypic plasticity and introduce examples to reinforce the potential importance of plastic compensation for understanding evolutionary change [Current Zoology 59 (4: 526–536, 2013].

    Full Text Available Reactive dyes are synthetic organic compounds used on a wide scale in textile industry, for painting materials of different types and compositions (e.g. 100% cotton, wool, natural satin, viscose, synthetic fibres. Reactive dyes are solid compounds (powders completely water soluble at normal temperature and pressure conditions. Their structures contain chromophore groups, which generate colour, and auxochrome groups, which determine the compounds water solubility and the capacity to fix to the textile fiber. Such organic compounds absorb UV-Vis radiations at specific wavelengths, corresponding to maximum absorbtion peaks, in both solution and dyed fiber. The human organism, through the dyed clothing, comes in direct contact with those dyes which can undergo modifications once exposed to UV radiations, having the posibility to reach the organism via cutanated transport. As it is known, the provoked negative effects are stronger during summer when UV radiations are more intense and in order to reduce their intensity dark coloured clothing is avoided. Dyes can be transformed in compounds which are easily absorbed into the skin. Some of these metabolites can be less toxic than the original corresponding dye, whilst others, such as free radicals, are potentially cancerous. Knowledge of the biological effects of the organic dyes, reactive dyes in particular, correlated with their structural and physical characteristics, permanently consists an issue of high scientific and practical interest and its solution may contribute in the diminishing of risk factors and improving of population health. UV radiation influence on the structural and colour modifications of textile materials were studied. Colour modifications are due to structural changes in aromatic and carbonil groups. In most cases photo-oxidative processes were identified in the dye structure. Dyeing was performed using non-irradiated and irradiated cotton painted with reactive blue dye 204.

    This study was conducted to improve the construction of impermeable clothing protecting against liquid chemical agents in order to lower the thermal strain caused by the clothing during work. Previous studies indicated that light work in a hot environment in this kind of clothing could last 30 min only. We propose a modification of the construction; new models of protective clothing were tested in wear trials. Then the results were compared with a basic model of impermeable protective clothing. Results indicated that all new models of protective clothing allowed workers to work 39-64% longer than in a basic model of protective clothing. Thus new clothing significantly improved comfort of work in impermeable protective clothing because of the lower thermal strain that it imposed on the user.

    Comparatively few studies have been carried out on air weapon injuries yet there are significant number of injuries and fatalities caused by these low power weapons because of their availability and the public perception that because they need no licence they are assumed to be safe. In this study ballistic gel was tested by Bloom and rupture tests to check on consistency of production. Two series of tests were carried out firing into unclothed gel blocks and blocks loosely covered by different items of clothing to simulate attire (tee shirt, jeans, fleece, and jacket). The damage to the clothing caused by different shaped pellets when fired at different ranges was examined. The apparent hole size was affected by the shape of pellet (round, pointed, flat and hollow point) and whether damage was predominantly caused by pushing yarn to one side or by laceration of the yarn through cutting or tearing. The study also compared penetration into clothed gel and unclothed gel under identical conditions, and loose clothing greatly reduced penetration. With loose clothing at 9.1 m range clothing reduced penetration to 50-70% of the penetration of unclothed gel but at 18.3m range only 7 out of 36 shots penetrated the gel. This cannot be accounted for by the energy loss at the longer range (3-7% reduction from 9.1 m to 18.3 m range in unclothed gels) and it is suggested that impulse may have a role to play. Shots that did not penetrate the gel were used to estimate the possible stopping time for the pellet (around 75 μs) and force (1700 N) or stress (100 MPa) required to bring the pellet to a halt. Even with these low energy projectiles, cloth fibres were entrained in the gel showing the potential for penetration of the body and subsequent infection. Copyright © 2014 Elsevier Ireland Ltd.

    Aviation security requires the detection of explosive devices which terrorists, posing as passengers, may conceal beneath their clothing. Our goal is to understand the generation, transport, and collection of trace signals from such concealed explosives, which are found in the natural convective plume produced by the human body. Previous work (APS/DFD96, CG10) has visualized this plume and shown that concealed volatile explosives (e.g. TNT) produce a detectable vapor signal therein. Plastic explosives, on the other hand, have vanishingly low vapor pressures and are thus considered very difficult to detect. Present experiments use a dispersal chamber to collect and sample the plumes of human subjects wearing concealed gauze patches containing milligrams of RDX, the primary component of plastic explosives such as C-4. These experiments address the effects of agitation, clothing, temperature and humidity on trace detectability. Further experiments address the effects of oily vs. dry skin, contaminated clothing vs. gauze patches, and residual contamination left on skin previously in contact with RDX. The key role of airborne contaminated textile fibers is noted. Knowledge thus gained contributes to the design of an explosive detection portal for aviation security screening.

    Full Text Available As part of the Europeana Cloud (eCloud project, Trinity College Dublin investigated best practice in the use of web services, such as APIs, for accessing large data sets from cultural heritage collections. This research looked into the provision and use of APIs, and moreover, whether or not more customised programmatic access to datasets is what researchers want or need. In order to understand whether current patterns of API usage reflect a skills gap on the part of researchers or a mismatch of tool to purpose, we looked not only at the creators and developer/users of APIs, but also at humanists already re-using big data; approaches in cultural heritage institutions and other research infrastructures to bring API use to non-technical audiences; and the kinds of training and other support services available or emerging within the data-intensive humanities research lifecycle. We conducted both desk research and a series of 11 interviews with figures working as researchers, developers or data providers, including figures from both the API development and the data usage communities. This research, conducted under the eCloud project and supported by the European Commission’s ICT Policy and Support Programme (Grant number 325091, was begun in March 2014 and is now in its concluding validation stage. The results of the research are not yet finalised, but the contribution is already emerging of this work to the debate about APIs being either the way forward for digital cultural heritage collections, or the Emperor’s New Clothes (or maybe a bit of both.

    The thermal insulation of clothing is one of the most important parameters used in the thermal comfort model adopted by the International Standards Organisation (ISO) [BS EN ISO 7730, 2005. Ergonomics of the thermal environment. Analytical determination and interpretation of thermal comfort using calculation of the PMV and PPD indices and local thermal comfort criteria. International Standardisation Organisation, Geneva.] and by ASHRAE [ASHRAE Handbook, 2005. Fundamentals. Chapter 8. American Society of Heating Refrigeration and Air-conditioning Engineers, Inc., 1791 Tullie Circle N.E., Atlanta, GA.]. To date, thermal insulation values of mainly Western clothing have been published with only minimal data being available for non-Western clothing. Thus, the objective of the present study is to measure and present the thermal insulation (clo) values of a number of Arabian Gulf garments as worn by males and females. The clothing ensembles and garments of Arabian Gulf males and females presented in this study are representative of those typically worn in the region during both summer and winter seasons. Measurements of total thermal insulation values (clo) were obtained using a male and a female shape thermal manikin in accordance with the definition of insulation as given in ISO 9920. In addition, the clothing area factors (f cl) determined in two different ways were compared. The first method used a photographic technique and the second a regression equation as proposed in ISO 9920, based on the insulation values of Arabian Gulf male and female garments and ensembles as they were determined in this study. In addition, fibre content, descriptions and weights of Arabian Gulf clothing have been recorded and tabulated in this study. The findings of this study are presented as additions to the existing knowledge base of clothing insulation, and provide for the first time data for Arabian Gulf clothing. The analysis showed that for these non-Western clothing designs, the

    By using the heritability-adjusted GGE biplot analysis method, and taking the trial sites Anqing, Nanyang, Huanggang, Jingzhou, Wuhan, Xiangyang, Changde, Yueyang, Nanjing, Nantong, Yancheng, Jiujiang, Jianyang, Shehong, and Cixi as the representative cotton-planting areas in the Yangtze River basin, the ecological regionalization of cotton varieties in the basin was made based on the lint cotton yield, and the regionalization results were adjusted by the information ratio (IR) method, aimed to provide scientific basis for the selection of cotton varieties in the cotton-planting areas of the basin. The cotton-planting areas in the Yangtze River basin could be divided into three ecological regions, i.e., the "Sichuan basin cotton region" with Jianyang and Shehong as the representative, the "Nan-Xiang basin cotton region" with Xiangyang and Nanyang as the representative, and the "majority complex cotton region in the Yangtze River basin" including all the other sites in the basin.

  15. Tests of Flammability of Cotton Fabrics and Expected Skin Burns in Microgravity

    During a shuttle launch and other portions of space flight, astronauts wear specialized flame resistant clothing. However during most of their missions on board the Space Shuttle or International Space Station, astronauts wear ordinary clothing, such as cotton shirts and pants. As the behaviour of flames is considerably different in microgravity than under earth s gravity, fabrics are expected to burn in a different fashion in microgravity than when tested on earth. There is interest in determining how this change in burning behaviour may affect times to second and third degree burn of human skin, and how the results of standard fabric flammability tests conducted under earth s gravity correlate with the expected fire behaviour of textiles in microgravity. A new experimental apparatus was developed to fit into the Spacecraft Fire Safety Facility (SFSF), which is used on NASA s KC-135 low gravity aircraft. The new apparatus was designed to be similar to the apparatus used in standard vertical flammability tests of fabrics. However, rather than using a laboratory burner, the apparatus uses a hot wire system to ignite 200 mm high by 80 mm wide fabric specimens. Fabric temperatures are measured using thermocouples and/or an infrared imaging system, while flame spread rates are measured using real time observations or video. Heat flux gauges are placed between 7 and 13 mm away from the fabric specimen, so that heat fluxes from the burning fabric to the skin can be estimated, along with predicted times required to produce skin burns.

    Experiments have been performed to demonstrate that near infrared (NIR) transmission through a wide range of clothing materials is possible. Studies have shown that the characteristics of NIR transmission are affected by both the type of fibre used, and the weave pattern. A series of experiments has indicated that NIR transmission is also dependent on other variables such as fabric porosity and dye colour. It is shown that, in many cases, transmission coefficients are sufficiently high that imaging and spectroscopy of objects hidden behind clothing samples should be possible. However, while transmission through clothing at NIR wavelengths in the 750-1,700 nm range is often more effective than in the visible or IR regions, the fabrics themselves will modify the transmitted signal in terms of spatial effects, intensity and spectral content. The paper also describes the possible use of near infrared signals to identify objects that are hidden behind clothing layers. This can be done using spectroscopy. It is important, however, to distinguish the various contributions that exist within the backscattered signal. A set of careful laboratory experiments have demonstrated that transmission through a set of different clothing fabrics does modify the spectral content of signals, but that the spectrum of a particular chemical can still be identified, provided certain steps are taken. These involve a set of careful calibration measurements, and the use of processing techniques for the retrieval of data. It will be shown that this is possible for both granular solids and selected liquids.

    Plaster of Paris (PoP) impregnated bandages have been used to maintain the position of bones and joints for over a century. Classically, wool dressing is applied to the limb before the PoP, which can then be moulded to the desired shape. A modification of this practice is to wrap the PoP bandages circumferentially in cotton before wetting and applying to the patient in an attempt to reduce inhalation of plaster dust and reduce mess. However, this may affect the water content of the cast and therefore also its setting properties and strength. This study compared the setting properties of PoP casts when used with and without cotton wrapping. Sixty specimens, compliant with the American Society for Testing and Materials standards for three-point bending tests, were prepared, with thirty wrapped in cotton. All were weighed before and after water immersion, and wrapped around a plastic cylinder to mimic limb application. Bending stiffness and yield strength was measured on a servohydraulic materials testing machine at 2, 6, 12, 24, 48 and 72 hours. The water content of cotton-wrapped plaster was significantly higher (50%) than that of standard plaster. It had significantly lower strength up to 24 hours and significantly lower stiffness up to 72 hours. The initial decrease in strength and stiffness of the cast wrapped in cotton may comprise the ability of the backslab to hold the joint or bone in an optimal position. Any modification of the standard plaster slab application technique should allow for the potential adverse effects on the plaster setting properties.

    Genetically modified (GM) cotton plants that effectively control cotton boll weevil (CBW), which is the most destructive cotton insect pest in South America, are reported here for the first time. This work presents the successful development of a new GM cotton with high resistance to CBW conferred by Cry10Aa toxin, a protein encoded by entomopathogenic Bacillus thuringiensis (Bt) gene. The plant transformation vector harbouring cry10Aa gene driven by the cotton ubiquitination-related promoter uceA1.7 was introduced into a Brazilian cotton cultivar by biolistic transformation. Quantitative PCR (qPCR) assays revealed high transcription levels of cry10Aa in both T0 GM cotton leaf and flower bud tissues. Southern blot and qPCR-based 2(-ΔΔCt) analyses revealed that T0 GM plants had either one or two transgene copies. Quantitative and qualitative analyses of Cry10Aa protein expression showed variable protein expression levels in both flower buds and leaves tissues of T0 GM cotton plants, ranging from approximately 3.0 to 14.0 μg g(-1) fresh tissue. CBW susceptibility bioassays, performed by feeding adults and larvae with T0 GM cotton leaves and flower buds, respectively, demonstrated a significant entomotoxic effect and a high level of CBW mortality (up to 100%). Molecular analysis revealed that transgene stability and entomotoxic effect to CBW were maintained in T1 generation as the Cry10Aa toxin expression levels remained high in both tissues, ranging from 4.05 to 19.57 μg g(-1) fresh tissue, and the CBW mortality rate remained around 100%. In conclusion, these Cry10Aa GM cotton plants represent a great advance in the control of the devastating CBW insect pest and can substantially impact cotton agribusiness.

    Full Text Available Bioethanol, as a clean and renewable fuel with its major environmental benefits, represents a promising biofuel today which is mostly used in combination with gasoline. It can be produced from different kinds of renewable feedstocks. Whereas the first generation of processes (saccharide-based have been well documented and are largely applied, the second and third generation of bioethanol processes (cellulose- or algae-based need further research and development since bioethanol yields are still too low to be economically viable. In this study, the possibilities of bioethanol production from cotton fabrics as valuable cellulosic raw material were investigated and presented. Potential lignocellulosic biomass for bioethanol production and their characteristics, especially cotton-based materials, were analyzed. Available lignocellulosic biomass, the production of textile and clothing and potential for sustainable bioethanol production in Serbia is presented. The progress possibilities are discussed in the domain of different pretreatment methods, optimization of enzymatic hydrolysis and different ethanol fermentation process modes.

    Contact burns from clothing irons are a common injury seen in children. These injuries occur when an unattended iron is within reach of toddlers in its upright position. In a previous study, the authors have shown that the surface of an iron takes 90 minutes to cool below the epidermal injury threshold of 49 degrees C. The authors have constructed an "iron shoe" to shield the iron surface from young hands during cooling. The device is intended to set the cooling iron in its down position providing additional protection. The device will insulate the iron surface to avoid the fire hazard when positioned in this manner. A silicone polymer was used to create an "iron shoe." This polymer is stable at temperatures up to 370 degrees C. The device included sidewalls to shield the edges from contact. Thermal analysis of the device was conducted using an inexpensive and expensive iron. Thermocouples were placed on the iron surface and below the iron shoe. The irons were heated to its maximum temperature, placed in the shoe and then unplugged. Temperature cooling curves were obtained from the thermocouples. The experiment was repeated by measuring the temperature difference between the iron edge and the shoe sidewalls. The surface of both expensive and inexpensive irons reached a maximum of 205 degrees C. The temperature below the iron shoe reached a maximum of 49 degrees C (inexpensive) and 60 degrees C (expensive). The iron edge temperature reached a maximum of 188 degrees C (inexpensive) and 154 degrees C (expensive). The shoe sidewall temperature achieved a maximum of 52 degrees C (inexpensive) and 49 degrees C (expensive). Both expensive and inexpensive irons reach temperatures over 200 degrees C. The silicone "iron shoe" effectively shielded the surface and edge of both irons and approached the epidermal injury threshold of 49 degrees C. The temperature beneath the expensive iron did exceed 49 degrees C, but because the intention of the device is to place the iron in

    Full Text Available The effect of periodate oxidation on the chemical and sorption properties of cotton yarn was investigated by determining aldehyde group content, moisture sorption, water retention and iodine sorption. Oxidation of cotton yarn was performed by varying concentration of sodium periodate solution and reaction time. To measure the aldehyde content present in the oxidized cotton, the aldehyde groups were selectively oxidized to carboxyl groups with sodium chlorite at pH 4-5, at room temperature for 48 h, and carboxyl group content was determined by modified calcium-acetate method. Differences in the sorption properties of untreated and oxidized cotton samples were obtained using conventional methods. The aldehyde groups were introduced into the oxidized cotton up to 99.2 µmol/g. Compared to the untreated fibers, oxidized cotton samples exhibited higher moisture sorption (up to 9% and lower water retention values (up to 19% and iodine sorption values (up to 31%. Based on the obtained results, it can be concluded that the crystalline structure of cellulose is not significantly changed by periodate oxidation, which is of great importance for textile material production.

    Full Text Available Chitosan is a biopolymer obtained from chitin, and among their most important aspects highlights its applications in a lot of industrial sectors due to its intrinsic properties, especially in the textile sector. In the last years, chitosan is widely used in the cotton and wool finishing processes due to its bond between them and its properties as an antifungical and antimicrobial properties. In this paper three different molecular weight chitosan are used in the finishing process of cotton to evaluate its influence in the surface properties modification. In order to evaluate the effect of the treatment with chitosan, flexural stiffness test is performed in warp and weft direction, and then the total value is calculated. The cotton fabric is treated with 5 g/L of different types of chitosan in an impregnation bath. This study shows the extent of surface properties modification of the cotton provided by three types of chitosan treatment. The results show that all types of chitosan modify the cotton flexural rigidity properties but the one which modifies it in a relevant manner is chitosan originated from shrimps.

    2011-04-01

    The response of a MEMS device that is exposed to a harsh environment may range from an increased noise floor to a completely erroneous output to temporary or even permanent device failure. One such harsh environment is high power acoustic energy possessing high frequency components. This type of environment sometimes occurs in small aerospace vehicles. In this type of operating environment, high frequency acoustic energy can be transferred to a MEMS gyroscope die through the device packaging. If the acoustic noise possesses a sufficiently strong component at the resonant frequency of the gyroscope, it will overexcite the motion of the proof mass, resulting in the deleterious effect of corrupted angular rate measurement. Therefore if the device or system packaging can be improved to sufficiently isolate the gyroscope die from environmental acoustic energy, the sensor may find new applications in this type of harsh environment. This research effort explored the use of microfibrous metallic cloth for isolating the gyroscope die from environmental acoustic excitation. Microfibrous cloth is a composite of fused, intermingled metal fibers and has a variety of typical uses involving chemical processing applications and filtering. Specifically, this research consisted of experimental evaluations of multiple layers of packed microfibrous cloth composed of sintered nickel material. The packed cloth was used to provide acoustic isolation for a test MEMS gyroscope, the Analog Devices ADXRS300. The results of this investigation revealed that the intermingling of the various fibers of the metallic cloth provided a significant contact area between the fiber strands and voids, which enhanced the acoustic damping of the material. As a result, the nickel cloth was discovered to be an effective acoustic isolation material for this particular MEMS gyroscope.

    Carcass mass largely affects pattern and rate of carrion decomposition. Supposedly, it is similarly important for carrion entomofauna; however, most of its likely effects have not been tested experimentally. Here, simultaneous effects of carcass mass and clothing are analyzed. A factorial block experiment with four levels of carcass mass (small carcasses 5-15 kg, medium carcasses 15.1-30 kg, medium/large carcasses 35-50 kg, large carcasses 55-70 kg) and two levels of carcass clothing (clothed and unclothed) was made in a grassland habitat of Western Poland. Pig carcasses (N = 24) were grouped into spring, early summer, and late summer blocks. Insects were sampled manually and with pitfall traps. Results demonstrate that insect assemblages are more complex, abundant, and long-lasting on larger carcasses, whereas clothing is of minor importance in this respect. Only large or medium/large carcasses were colonized by all guilds of carrion insects, while small or medium carcasses revealed high underrepresentation of late-colonizing insects (e.g., Cleridae or Nitidulidae). This finding indicates that carcasses weighing about 23 kg-a standard in forensic decomposition studies-give an incomplete picture of carrion entomofauna. Residencies of all forensically relevant insects were distinctly prolonged on larger carcasses, indicating that cadaver mass is a factor of great importance in this respect. The pre-appearance interval of most taxa was found to be unrelated to mass or clothing of a carcass. Moreover, current results suggest that rate of larval development is higher on smaller carcasses. In conclusion, this study demonstrates that carcass mass is a factor of crucial importance for carrion entomofauna, whereas the importance of clothing is small.

    Under-mulch-drip irrigation is an advanced irrigation technique, which combines plastic-film-covered cultivation with drip irrigation. The influence of different norms of under-mulch-drip irrigation on di-urnal changes of photosynthetic rates and chlorophyll fluorescence parameters of cotton was studied, in orderto understand the physiological mechanisms of water-saving and high-yielding farming in Xinjiang. Results in-dicated that limited drip irrigation, which supplies 2/3 of 375 m3 ha-1 , the widely-used irrigation norm in cot-ton cultivation in Xinjiang, caused a water deficit in cotton field. Compared with the proper drip irrigation,the leaf photosynthetic rate under limited drip irrigation decreased during 9:00 to 11:00 a. m., and was sig-nificantly suppressed at midday, and then recovered afterwards. Using the chlorophyll fluorescence method,the absorption, transfer and transformation features of solar radiation by cotton leaf were investigated. Underlimited drip irrigation, the variable fluorescence (Fy) and primary light transfer efficiency of PSII (Fv/Fm)in cotton leaves were reduced because of the high light intensities and high temperatures at noon, and the de-crease in Xinluzao8 was greater than that in Xinluzao6. Therefore, it could be concluded that Xinluzao6 has ahigher drought-tolerance, and the Fv/Fm ratio could be used as a drought-resistance index for cotton.

    The primary purpose of this research was to give suitable irrigation program according to the growth period and water requirement.A cotton field experiment with mulched drip irrigation was conducted at the National Field Observation and Research Station for Oasis Farmland Ecosystem in Aksu of Xinjiang in 2008.Water balance method was adopted to study the water requirement and water consumption law of cotton under mulched drip irrigation in Tarim Irrigated Area.Statistical analysis of experimental data of irrigation indicates that the relationship between yield of cotton and irrigation presents a quadratic parabola.We fit the model of cotton water production on the basis of field experimental data of cotton.And the analysis on water saving benefit of cotton under mulched drip irrigation was done.Results indicate that water requirements for the irrigated cotton are 543 mm in Tarim Irrigated Area.The water requirements of seedling stage is 252 mm,budding stage is 186 mm,bolling stage is 316 mm and wadding stage is 139 mm.the irrigation amount determines the spatial distribution of soil moisture and water consumption during cotton life cycle.However,water consumption at different growth stages was inconsistent with irrigation.Quantitatively,the water consumed by cotton decreases upon the increase of irrigation amount.From the perspective of water saving,the maximal water use efficiency can reach 3 091 m3/ha.But the highest cotton yield needs 3464 m3/ha irrigation water.In summary,compared to the conventional drip irrigation,a number of benefits in water saving and yield increase were observed when using plastic mulch.At the same amount of irrigation,the cotton yield with plastic mulch was 30.2% higher than conventional approaches,and the efficiency of water utilization increased by30.2%.While at the same yield level,29.3% water was saved by using plastic mulch,and the efficiency increased by 41.5%.

    2010-12-01

    There has being a change in cotton cultivative practice in the northwestern China, i.e., from the traditional cultivation (TF) of no mulching with flood-irrigation to the modern cultivation (PM) of plastic film mulching with drip-irrigation. Little is known how this change affects soil carbon dynamics. This paper presents a field study that includes comparisons of soil organic carbon (SOC), soil CO2 concentration and soil surface CO2 efflux during cotton growing season. At the initial growing stage, SOC content was similar between TF and PM, showing a clear decreasing trend over depth (i.e., ~9 g/kg, ~7.5 g/kg and ~3 g/kg at 0-20 cm, 20-30 cm and 30-70 cm, respectively). After five months, SOC generally decreased at 0-20 cm but increased below 30 cm. Overal, SOC was higher in the surface soil in the PM than in the TF, particularly at 20-30 cm where SOC reached ~9 g/kg in the PM. In general, CO2 concentration in soil profile was higher in the PM (3107 - 9212 ppmv) than in the TF (1275 - 8994 ppmv). However, rate of CO2 efflux was lower in the PM than in the TF, primarily owing to plastic film covering. For the whole cotton growing season, accumulated rates of CO2 efflux were 300 g C m-2 and 394 g C m-2 in the PM and the TF, respectively. Fig. 1. Soil organic carbon (SOC) in (a) May (b) August and (c) October between plastic film mulching cultivation (PM) and traditional flooding cultivation (TF). Table 1.

  14. THE RELATIONSHIP BETWEEN WORDS, TEXTS, CLOTHES AND TEXTILES

    Directory of Open Access Journals (Sweden)

    STURZA Amalia

    2017-05-01

    Full Text Available In this paper we will speculate the possible relationships between “word,” “text,” “textile,” and “clothing”. Many of the terms we use to describe our interactions with words are derived from the common linguistic root and numerous other expressions associated with reading and writing are drawn from the rich vocabulary of cloth. Textiles are one of the most ubiquitous components of material culture and they are also integral to the material history of texts. The intersection between texts and textiles locates the relationship between language and dress, as together they structure the fashion scene over the century. We compare these texts and storytelling with the process of making clothes, they go from fibers that are spun and then create the fabric or the material out of which the clothes are made. Besides the similitude of the words “text” and “textile” that have four similar letters there is also the resemblance in the way they transmit a message. While texts are meant to transmit something to the reader, to enchant and to create emotions in so various ways, just in the same way clothes are also meant to transmit emotions and feelings to the wearer or to the people watching them.

    2016-09-01

    We report on the successful use of direct PCR amplification of single fibers from items of worn clothing. Items of clothing were worn throughout the course of a day, with the individual commencing regular activities. Single fibers were taken from the cuff of the clothing at regular intervals and amplified directly. The same areas were subjected to tape-lifting, and also amplified directly for comparison. The NGM™ kit that amplifies 15 STR loci plus amelogenin was used. A total of 35 single fiber samples were processed and analyzed from five items of clothing, with 81 % of samples returning a profile of 14 alleles or more. All tape-lift samples amplified directly produced DNA profiles of 15 alleles or more. The aim was to develop a simple, operational method that could be used routinely in forensic science casework and that has the potential to generate more complete profiles, which would not be detected using standard extraction methods on this type of sample. For ease of implementation, the process also adheres to standard methods with no increase in the cycle number.

    2015-12-10

    A method of coloration of cotton fabrics with nano chitosan is proposed. Nano chitosan were prepared using crab shell chitin nanofibers through alkaline deacetylation process. Average nano fiber diameters of nano chitosan were 18 nm to 35 nm and the lengths were in the range of 0.2-1.3 μm according to the atomic force microscope study. The degree of deacetylation of the material was found to be 97.3%. The prepared nano chitosan dyed using acid blue 25 (2-anthraquinonesulfonic acid) and used as the coloration agent for cotton fibers. Simple wet immersion method was used to color the cotton fabrics by nano chitosan dispersion followed by acid vapor treatment. Scanning electron microscope and atomic force microscope study of the treated cotton fiber revealed that the nano chitosan were consistently deposited on the cotton fiber surface and transformed in to a thin polymer layer upon the acid vapor treatment. The color strength of the dyed fabrics could be changed by changing the concentration of dyed nano chitosan dispersion.

  9. More on Cotton Flow on Three Manifolds

    CERN Document Server

    Kilicarslan, Ercan; Tekin, Bayram

    2015-01-01

    Cotton flow tends to evolve a given initial metric on a three manifold to a conformally flat one. Here we expound upon the earlier work on Cotton flow and study the linearized version of it around a generic initial metric by employing a modified form of the DeTurck trick. We show that the flow around the flat space, as a critical point, reduces to an anisotropic generalization of linearized KdV equation with complex dispersion relations one of which is an unstable mode, rendering the the flat space unstable under small perturbations. We also show that Einstein spaces and some conformally flat non-Einstein spaces are linearly unstable. We refine the gradient flow formalism and compute the second variation of the entropy and show that generic critical points are extended Cotton solitons. We study some properties of these solutions and find a Topologically Massive soliton that is built from Cotton and Ricci solitons. In the Lorentzian signature, we also show that the pp-wave metrics are both Cotton and Ricci sol...

    Full Text Available Background: Long term occupational exposure to cotton dust is associated with respiratory symptoms and loss of pulmonary function. Aim: This study was conducted to explore respiratory symptoms, pulmonary function tests and chest radiography of workers, and to evaluate the findings of high resolution computed tomographyand its correlation with pulmonary function tests (PFT. Material and Methods: The study was conducted on 100 cotton workers as exposed group and 100 unexposed subjects. Smokers were excluded from the study. All workers were interviewed and examined by the pulmonologist. PFT and chest radiography were conducted for all subjects. HRCT was performed for those with abnormal PFT or chest radiography. Results: A total of 51% and 31% of the cotton textile workers had one or more respiratory symptoms and respiratory signs respectively. 28% of subjects in the exposed group and 5% of subjects in unexposed group had obstructive pattern. Bronchia wall thickening and air trapping were the most frequent chest radiography and HRCT abnormalities respectively. There was a significant correlation between HRCT and the results of PFT. Conclusion: We conclude that long term exposure to cotton dust is associated with obstructive disease that increase with duration of exposure (history of working years, also use of HRCT as a sensitive tool in the assessment of pathologic changes and it's correlation with PFT, confirms the expected pathophysiology of airway obstruction in cotton workers.

  11. The chemical recycle of cotton

    Alice Beyer Schuch

    2016-09-01

    Full Text Available The chemical recycle of cotton textiles and/or other cellulosic materials for the purpose of manufacturing regenerated high quality textiles fibres is a novel process. The objective of related research is based on the forecast of population growth, on resource scarcity predictions, and on the negative environmental impact of the textile industry. These facts lead the need of broadening the scope for long-term textile-to-textile recycle - as the mechanical recycle of natural fibres serve for limited number of cycles, still depends on input of virgin material, and offer a reduced-in-quality output. Critical analysis of scientific papers, relevant related reports, and personal interviews were the base of this study, which shows viable results in laboratorial scale of using low-quality cellulosic materials as input for the development of high-quality regenerated textile fibres though ecological chemical process. Nevertheless, to scale up and implement this innovative recycle method, other peripheral structures are requested, such as recover schemes or appropriate sort, for instance. Further researches should also be considered in regards to colours and impurities.

    Haonan Zhang

    Full Text Available Transgenic crops producing Bacillus thuringiensis (Bt toxins kill some key insect pests, but evolution of resistance by pests can reduce their efficacy. The predominant strategy for delaying pest resistance to Bt crops requires refuges of non-Bt host plants to promote survival of susceptible pests. To delay pest resistance to transgenic cotton producing Bt toxin Cry1Ac, farmers in the United States and Australia planted refuges of non-Bt cotton, while farmers in China have relied on "natural" refuges of non-Bt host plants other than cotton. Here we report data from a 2010 survey showing field-evolved resistance to Cry1Ac of the major target pest, cotton bollworm (Helicoverpa armigera, in northern China. Laboratory bioassay results show that susceptibility to Cry1Ac was significantly lower in 13 field populations from northern China, where Bt cotton has been planted intensively, than in two populations from sites in northwestern China where exposure to Bt cotton has been limited. Susceptibility to Bt toxin Cry2Ab did not differ between northern and northwestern China, demonstrating that resistance to Cry1Ac did not cause cross-resistance to Cry2Ab, and implying that resistance to Cry1Ac in northern China is a specific adaptation caused by exposure to this toxin in Bt cotton. Despite the resistance detected in laboratory bioassays, control failures of Bt cotton have not been reported in China. This early warning may spur proactive countermeasures, including a switch to transgenic cotton producing two or more toxins distinct from Cry1A toxins.

    2016-05-01

    One of the major criteria used for advancing experimental lines in a breeding program is yield performance. Obtaining yield performance data requires machine picking each plot with a cotton picker, modified to weigh individual plots. Harvesting thousands of small field plots requires a great deal of time and resources. The efficiency of cotton breeding could be increased significantly while the cost could be decreased with the availability of accurate methods to predict yield performance. This work is investigating the feasibility of using an image processing technique using a commercial off-the-shelf (COTS) camera mounted on a small Unmanned Aerial Vehicle (sUAV) to collect normal RGB images in predicting cotton yield on small plot. An orthonormal image was generated from multiple images and used to process multiple, segmented plots. A Gaussian blur was used to eliminate the high frequency component of the images, which corresponds to the cotton pixels, and used image subtraction technique to generate high frequency pixel images. The cotton pixels were then separated using k-means cluster with 5 classes. Based on the current work, the calculated percentage cotton area was computed using the generated high frequency image (cotton pixels) divided by the total area of the plot. Preliminary results showed (five flights, 3 altitudes) that cotton cover on multiple pre-selected 227 sq. m. plots produce an average of 8% which translate to approximately 22.3 kgs. of cotton. The yield prediction equation generated from the test site was then use on a separate validation site and produced a prediction error of less than 10%. In summary, the results indicate that a COTS camera with an appropriate image processing technique can produce results that are comparable to expensive sensors.

    1996-12-01

    Today's clothing market is not adapted for people with unusual body dimensions and/or different kinds of functional impairments. They will be referred to as disabled users. The method of user-oriented product development combined with the soft systems methodology has been applied in order to understand and possibly solve their problem. Sixty five disabled users were interviewed. The results show that the disabled users must be divided into subgroups. Their requirements are very much dependent on their impairment not only regarding the fit and function of the clothing, but also regarding shopping and service in the stores. The symbolic values of clothing are just as important as the functional values. However, it is essential not to focus on the end product only, but to look at the problem as a system consisting of: manufacturing, marketing and end use. A new method of taking three dimensional measurements from range images of the human body has been developed. In combination with other developments in information technology it will be possible to synthesise a new system where the manufacturers and retailers of clothing can co-operate in order to give service to disabled users.

    Full Text Available There is much interest in the role that agricultural practices might play in sequestering carbon to help offset rising atmospheric CO₂ concentrations. However, limited information exists regarding the potential for increased carbon sequestration of different management strategies. The objective of this study was to quantify and contrast carbon dioxide exchange in traditional non-mulching with flooding irrigation (TF and plastic film mulching with drip irrigation (PM cotton (Gossypium hirsutum L. fields in northwest China. Net primary productivity (NPP, soil heterotrophic respiration (R(h and net ecosystem productivity (NEP were measured during the growing seasons in 2009 and 2010. As compared with TF, PM significantly increased the aboveground and belowground biomass and the NPP (340 g C m⁻² season⁻¹ of cotton, and decreased the R(h (89 g C m⁻² season⁻¹ (p<0.05. In a growing season, PM had a higher carbon sequestration in terms of NEP of ∼ 429 g C m⁻² season⁻¹ than the TF. These results demonstrate that conversion of this type of land use to mulching practices is an effective way to increase carbon sequestration in the short term in cotton systems of arid areas.

    Full Text Available With the increasing of population and the reduction of available land, more and more construction of buildings and other civil engineering structures have to be carried out on weak or soft soil. Owing to such soil of poor shear strength and high swelling & shrinkage, a great diversity of ground improvement techniques such as soil stabilization and reinforcement are employed to improve mechanical behavior of soil, thereby enhancing the reliability of construction. Black cotton soil is one of the major soil deposits of India. They exhibit high swelling and shrinking when exposed to changes in moisture content and hence have been found to be most troublesome from engineering considerations. Stabilization occurs when lime is added to black cotton soil and a pozzolanic reaction takes place. The hydrated lime reacts with the clay particles and permanently transforms them into a strong cementations matrix. Black cotton soil showing low to medium swelling potential from Rajkot Gujarat was used for determining the basic properties of the soil. Changes in various soil properties such as Liquid limit, Plastic Limit, Maximum Dry Density, Optimum Moisture Content, and California Bearing Ratio were studied. Keywords–

    Monopolistic clothing store is the best place for clothing industry to present the complete identity and distinctive style of brands. Actually the brand identity is reflected not only from clothes itself, but also from different aspects, e.g. an ornament, a brochure, a logo, and a clothes rack, or the outside appearance of the store, the window display and the inside environment. So monopolistic clothing store should focus on promoting the philosophy of brand and present the brand identity in its visual designs.

    There are many methods and techniques that can be used to transfer foreign genes into cells. In plant biotechnology, Agrobacterium-mediated transformation is a widely used traditional method for inserting foreign genes into plant genome and obtaining transgenic plants, particularly for dicot plant species. Agrobacterium-mediated transformation of cotton involves several important and also critical steps, which includes coculture of cotton explants with Agrobacterium, induction and selection of stable transgenic cell lines, recovery of plants from transgenic cells majorly through somatic embryogenesis, and detection and expression analysis of transgenic plants. In this chapter, we describe a detailed step-by-step protocol for obtaining transgenic cotton plants via Agrobacterium-mediated transformation.

    Poplar-cotton agro-ecosystems are the main agricultural planting modes of plain cotton fields in China. Here, we performed a systematic survey of the diversity and population of arthropod communities in four different combination of poplar-cotton eco-systems, including I) non-transgenic poplar and non-transgenic cotton fields; II) non-transgenic poplar and transgenic cotton fields [Bacillus thuringiensis (Bt) cotton]; III) Bt transgenic poplar (high insect resistant strain Pb29) and non-transgenic cotton; and IV) transgenic poplar and transgenic cotton fields, over a period of 3 years. Based on the statistical methods used to investigate community ecology, the effects of transgenic ecosystems on the whole structure of the arthropod community, on the structure of arthropods in the nutritive layer, and on the similarity of arthropod communities were evaluated. The main results were as follows: the transgenic poplar-cotton ecosystem has a stronger inhibitory effect on insect pests and has no impact on the structure of the arthropod community, and therefore, maintains the diversity of the arthropod community. The character index of the community indicated that the structure of the arthropod community of the transgenic poplar-cotton ecosystem was better than that of the poplar-cotton ecosystem, and that system IV had the best structure. As for the abundance of nutritional classes, the transgenic poplar-cotton ecosystem was also better than that of the non-transgenic poplar-cotton ecosystem. The cluster analysis and similarity of arthropod communities between the four different transgenic poplar-cotton ecosystems illustrated that the structure of the arthropod community excelled in the small sample of the transgenic poplar-cotton ecosystems.

  9. The persistence of human scalp hair on clothing fabrics.

    2003-12-17

    This study reports the persistence behaviour of human scalp hairs under a number of different circumstances. The effects of artificial dyeing of hairs, the presence or absence of roots and different types of fabrics on the persistence of hair on a variety of garments were investigated. The garments were made from cotton, polycotton, cotton/acrylic, polyester and wool. The results indicated that neither artificial dyes nor the presence or absence of roots had statistically significant effects on the persistence of hair. In contrast, the type of fabric had a major impact and it was found that, generally, hairs persist longer on rougher fabrics. The rate of loss of hairs from non-woollen fabrics during normal wear was found to follow an exponential decay curve. In contrast, the rate of loss from the woollen garments was quite linear, indicating a constant, even loss, and thus suggests that a different process is involved in the persistence of hairs on woollen garments from that on non-woollen garments. The speed at which hair was lost from fabrics decreased in the order polyester, cotton/acrylic, polycotton, cotton, smooth wool, rough wool, so that wool gives the best chance of recovering samples of hair. Due to the uniqueness of each case, it is advised that caution be used when making any interpretations and before drawing any conclusions.

    Full Text Available Young consumers are the stylish shoppers who have a strong tendency to follow the latest fashion. With the rapid changes in the fashion trends, the overconsumption of clothing has had a significant environmental impact on society. Hence, there is a need to understand how young fashionable consumers are disposing their unwanted clothes. The survey was conducted among 205 young respondents, and the results show that clothing disposal behavior is affected by philanthropic awareness and mediated by the attitude toward clothing disposal. Interestingly, environmental economic factors only influence clothing disposal behavior through the attitude toward the disposal of clothing. The findings provide a valuable insight into the government and related authorities or organizations in developing strategies to encourage young consumers to increase their clothing-recycling rate, and, thus, eliminate the environmental issues in near future.

    Cotton (Gossypium herbaceum L.) fibers elongated almost linearly up to about 20 days post anthesis. The molecular mass of xyloglucans in fiber cell walls decreased gradually during the elongation stage. When enzymatically active (native) cell wall preparations of fibers were autolyzed, the molecular mass of xyloglucans decreased. The decrease was most prominent in wall preparations obtained from the rapidly elongating fibers. The xyloglucan-degrading activity was recovered from the fiber cell walls with 3 mol/L NaCl, and the activity was high at the stages in which fibers elongated vigorously. These results suggest the possible involvement of xyloglucan metabolism in the regulation of cotton fiber elongation.

    Apart from helmets, little is known about the effectiveness of motorcycle protective clothing in reducing injuries in crashes. The study aimed to quantify the association between usage of motorcycle clothing and injury in crashes. Cross-sectional analytic study. Crashed motorcyclists (n=212, 71% of identified eligible cases) were recruited through hospitals and motorcycle repair services. Data was obtained through structured face-to-face interviews. The main outcome was hospitalization and motorcycle crash-related injury. Poisson regression was used to estimate relative risk (RR) and 95% confidence intervals for injury adjusting for potential confounders. Motorcyclists were significantly less likely to be admitted to hospital if they crashed wearing motorcycle jackets (RR=0.79, 95% CI: 0.69-0.91), pants (RR=0.49, 95% CI: 0.25-0.94), or gloves (RR=0.41, 95% CI: 0.26-0.66). When garments included fitted body armour there was a significantly reduced risk of injury to the upper body (RR=0.77, 95% CI: 0.66-0.89), hands and wrists (RR=0.55, 95% CI: 0.38-0.81), legs (RR=0.60, 95% CI: 0.40-0.90), feet and ankles (RR=0.54, 95% CI: 0.35-0.83). Non-motorcycle boots were also associated with a reduced risk of injury compared to shoes or joggers (RR=0.46, 95% CI: 0.28-0.75). No association between use of body armour and risk of fracture injuries was detected. A substantial proportion of motorcycle designed gloves (25.7%), jackets (29.7%) and pants (28.1%) were assessed to have failed due to material damage in the crash. Motorcycle protective clothing is associated with reduced risk and severity of crash related injury and hospitalization, particularly when fitted with body armour. The proportion of clothing items that failed under crash conditions indicates a need for improved quality control. While mandating usage of protective clothing is not recommended, consideration could be given to providing incentives for usage of protective clothing, such as tax exemptions for safety
