Current firefighter protective clothing is composed of multilayer fabric systems. The outer shell fabrics inevitably become wet in the process of firefighters performing their duties, and sweat may also increase moisture in the inner layers of protective clothing. In this study, two kinds of outer shell fabrics (aramid IIIA fabric and aramid 1313 and flame-retardant viscose-blended fabric) and two kinds of thermal liner fabrics with different thicknesses were selected. Three wetness conditions were simulated for the outer shell fabric, thermal liner fabric and both fabrics together. A modified thermal protective performance (TPP) tester was applied to assess TPP provided by these wetted fabrics; in addition, second-degree skin burn time was predicted and absorbed energy indexes were calculated. The regression method was employed to create fitting curves for absorbed energy and second-degree burn time in different configurations and the Pearson correlation was established to analyze their relationship, in which the lowest R2 value could reach 0.9122 and p-values were all much less than 0.05. Performance results for both wet conditions indicated that outer shell moisture and a thicker thermal liner have a positive and increased negative effect, respectively, on fabric TPP. When the sample S-3-D (aramid 1313 and flame-retardant viscose-blended fabric, moisture barrier and the thin thermal liner) was both wetted in the outer shell and thermal liner, its second-degree burn time was improved by 12.8% over performance in dry conditions. These findings may have important applications for the design and manufacture of optimal protective performance clothing systems.

Full textAbstract:
In this study, dimensional and some physical properties of plain (single jersey) and lacoste knitted fabrics made from 50/50 modal/combed cotton blended yarns (tex 21 and 15) were investigated. Twelve weft knitted fabrics were produced with two different structures and three different densities (loose, medium, tight). For physical properties, the fabric weight per unit area, fabric thickness, bursting strength, air permeability and dimensional stability were evaluated. We focused on the dimensional stability properties of outwear knitted fabrics. The total dimensional change of the fabric’s dimensions and structural properties were measured and evaluated after ten washing cycles and then flat dried. The results show that the weight per unit area, thickness, air permeability and dimensional stability values are independent of the yarn linear density, fabric structure and fabric density. Statistically evaluated using Design Expert Analysis of variance (ANOVA) software 6.06., test results show that dimensional stability is mostly effective for the bursting strength, air permeability and fabric weight per unit area.

Full textAbstract:
In order to develop the traditional technique and variety colors of Xiangyunsha, Doscorea Cirrhosa extract was applied on silk fabric, and three metal ion agents Fe2+, Zn2+ and Ti4+ were used as post treatment mordant. Different silk fabrics with three colors were obtained: black, pale yellow and orange yellow. And metal salt post treatment also increased the color fastness of finished fabric. The optimal technological conditions were achieved through orthogonal experiments. The washing fastness of three metal salts treated fabrics was measured. The staining fastness was good, but the fading fastness was medium. Among of the three mordants treated fabrics, the washing fastness of Zn2+ post treated fabric was the best. Crocking fastness and sunlight fastness of Doscorea Cirrhosa treated silk fabric could be improved by metal salt treatment. The UV-resistant property of silk fabric was improved to an encouraging level, which benefited the silk cloth especially because silk was commonly applied for summer wear. And the gas permeability of treated sample was acceptable.

Full textAbstract:
The bio-scouring of cotton using protease and pectinase produced from Bacillus subtilis was investigated. Protease and pectinase were produced from Bacillus subtilis in a liquid medium using the submerged fermentation technique. Both enzymes were purified, and their scouring potential was tested on raw cotton fabrics. Pectinase was more effective than protease under optimised conditions. The optimum scouring temperature for both enzymes was between 40 °C and 50 °C, with pectinase bio-scoured fabric showing 15.5% weight loss while protease bio-scoured fabric had 14.3% weight loss. The optimum pH for pectinase scouring was pH 9 with 14.8% weight loss in the fabric, while the optimum pH for protease scoured fabric was pH 7 with 12.3% weight loss in fabric. After 120 minutes of bio-scouring, maximum weight loss was recorded for both pectinase and protease treated fabrics. The application of protease and pectinase for cotton fabric scouring revealed that they could be used as bio-scouring agents to treat textile materials.

Full textAbstract:
Denim fabric is one of the most popular casual wear fabrics worldwide. The performance characteristics of denim fabrics have been improved by using functional fibers and elastane to make them comfortable to wear. Elastane fibers with high elasticity are used extensively in denim fabric production. Elastane fibers are generally used as the core part of the core-spun yarns as weft yarns. Besides elastane fibers; polyester and polyester derivatives are commonly used. This study examines the effects of filament fineness and yarn count on denim fabric performance. Textured polyester filaments with medium, fine and micro linear densities were used as the core part of the core-spun yarn and cotton fiber was used as sheath material. Yarn samples manufactured with the same production parameters at different yarn count were used as weft yarns of denim fabrics. Denim fabrics were produced with the same fabric cover factor to eliminate yarn count difference effects. Tensile, static tearing and dynamic tearing properties of denim fabrics were determined. To evaluate the effects of core part, 100 % cotton denim fabric was manufactured and tested. Statistical analysis was performed to analyze the significance of filament fineness and yarn count ratio. Results showed that there was a significant effect of filament fineness on tensile, static tearing and dynamic tearing properties of denim fabrics. In addition, it was found that yarn count had no significance effect on static tearing properties of denim fabrics.

Full textAbstract:
In this paper, the author applies the principle of information theory to probe the role that experience plays in the process of fabric hand evaluation. 8 experts and 8 non-experts, two group judges assessed 8 medium-weight worsted fabrics for men’s suiting. The results have been analysed. The data show that the expert group has the higher ability of handling instinct attributes of a fabric than the non-expert group do. In other words, the experts seem to be more sensitive to the change of fabric physical and mechanical properties than the non-experts. And when a expert assesses a fabric by hand, he introduces few subjective factors, that is to say, the result of the evaluation of touch quality of a fabric by a expert has higher objectivity or reliability. This may provide a fundamental or a train of thought for the objective assessment of fabric hand in textile science and technology.

Full textAbstract:
Different historical backgrounds and planning ideas have created different urban streetscape fabrics. The patterns of the streetscape fabric have affected urban microclimate factors and formed a unique local microclimate. This paper simulated the microclimatic effects in four study areas with different streetscape fabrics in Shanghai to compare the microclimatic conditions with a system of multi-dimensional street morphological indices using ENVI-met 4.3 software. At the street network fabric level, the results showed that streets with a south–north orientation, a small junction spacing, and a street network with better connectivity were conducive to mitigation of the air temperature heating intensity in the street space and improving the ventilation effect; at the street-site level: The indices of Build-to-line ratio (BL), Height-width ratio (H/W), and Sky view factors (SVF) played different roles that affected the distribution characteristics of the microclimate factors. The BL value of the streets between 0.5 and 0.8 generally had a positive relationship with the air temperature. The SVF value of the streets was positively correlated with the microclimate index, while the H/W values were negatively correlated with them. The morphological indicators of different levels also had a synergistic effect on the microclimatic impact of the street space fabric. This comparative analysis of microclimatic characteristics at the medium spatial scale will provide useful suggestions for urban climate adaptability in urban spatial morphology optimization in future urbanization development.

Natural color cotton is eco-supportive as they possess colour naturally in varied shades viz., brown, green, cream and other tints and shades of these colours. It has unique comfort and handle property which provides soothing to the wearer. A medium brown natural colour cotton fibre was spun into 20s count yarn on open end spinning and the pure colour cotton fabric was developed on handloom and subjected to scouring. The scoured natural colour cotton fabric undergone with multiple wash cycles and assessed for mechanical, functional properties, colour fastness to sunlight and washing properties. Results revealed that, the scoured natural color cotton fabrics at washing and sunlight was found to be increase in color strength and decrease in reflectance than the pure NCC fabric. After laundering at multiple washes, the scoured natural colour cotton fabric exposed to direct sunlight, it was found that the colour strength was significantly reduced and fabric became lighter, duller and yellower. However, the scoured natural colour cotton fabric subjected to washing and shade dried exhibited significantly greater K/S, which indicates the sample became darker, brighter and greener than the sample expose to direct sunlight. The natural colour cotton fabrics has better mechanical, functional and fastness properties can be suitable for production of diversified cotton products ranging from children garments to trendy outfits. Hence, the promotion of natural colour cotton fabrics is a sustainable approach for green environment.

The number of electrical and electronic devices in our daily life has increased. The devices produce electromagnetic waves which harm human and environments. In recent years, there has been an increasing interest in the reduction and control of electromagnetic waves. The paper focuses on shielding of electromagnetic waves of nonwoven fabrics produced with needle punching technology from conductive stainless steel fibers. The needle punched nonwoven fabrics were produced with carding and needle punching technology by blending stainless steel fibers and normal staple polyester fibers at different ratios for electromagnetic shielding applications. The electromagnetic shielding effectiveness of the nonwoven fabrics with conductive stainless steel fibers was tested. After blending of stainless steel fibers and normal polyester fibers, the webs were formed by a wool-type carding machine and the after web folding operation, the webs were bonded by needle punching at constant working parameters. During production, the needle punch densities per cm2 and needle penetration depth per mm were kept constant. Bulky needle punched nonwoven fabrics with low needling density were produced. The main objective of our research was to develop the nonwoven fabric for shielding against electromagnetic waves. In addition, the effect of the stainless steel fiber ratio used in the needle punched nonwoven fabrics on electromagnetic shielding effectiveness was investigated. After production, the thicknesses of the needle punched nonwoven fabrics were tested. The electromagnetic shielding effectiveness, reflection and absorption values of the needle punched nonwoven fabric samples were measured at the frequency range of 15-3000MHz and presented in table and graphics. As the ratio of stainless steel fibers used in the nonwoven fabric increased, Electromagnetic shielding effectiveness values (EMSE) were increased in a linear manner and obtained results were discussed. It was found that the electromagnetic waves were shielded about 90% at high frequencies, 85% at medium frequencies, and 80% at low frequencies by needle punched nonwoven fabric with 5% conductive stainless steel fiber. The EMSE values such as 20dB, 25dB and 45dB were obtained at low frequency ranges (0–300MHz and 25dB, medium frequency ranges, 300-1200MHz and 45dB, and high frequency ranges, 1200-3000MHz) with the needle punched nonwoven fabric containing 25% conductive stainless steel fiber.

Wool fiber has a complex hierarchic structure. The multi-scale fibrils are assembled to form a tree-like channel net in wool fiber, providing an efficient heat transfer property. The optimal inner configuration of wool fiber can also be invited to biomimic design of textile fabrics to improve the thermal comfort of cloth. A heat transfer model of biomimic multi-scale fabric using the fractal derivative is established. Theoretical analysis indicates that the heat flux efficiency in the biomimic fabric can be 2 orders of magnitude comparing with that of the continuous medium.

The aims of this study were to identify the optimal combination of knitted fabric properties that influence the sensation of coolness and to ascertain the relationship between subjective and objective coolness measurements. Test fabrics included eight cool-touch nylon knitted fabrics and four other knitted fabrics. The physical properties and surface characteristics of the fabrics were assessed. Coolness sensation was determined by the Thermolabo II instrument to provide an objective measurement, expressed as Qmax. A forearm test and palm-of-hand test were used as subjective measurements. Pore volume ratio and geometric roughness had a significant effect on coolness sensation expressed via Qmax. Stiffness and weight influenced the forearm test. Pore volume ratio and the coefficient of steel–fabric friction affected the coolness sensation measured by the palm-of-hand test. Nylon/spandex (78/22) tricot was the coolest of all samples, such that its characteristics were thought to represent the optimal combination of knitted fabric properties for a cooling fabric, that is, a high and balanced stitch density of 150 × 130, light in weight of 161.4 g/m2, a pore volume ratio of 69.4%, medium geometric roughness, and a thin pliable knitted fabric. The objective measurements were highly correlated with the palm-of-hand test, but not with the forearm test because only the palm-of-hand test had a test set-up that was similar to the objective test. Although the objective and forearm test set-ups were only slightly different, coolness assessed with the forearm test was not correlated with coolness assessed with objective measurements.

Textile structures with various bioactive and functional properties are used in many areas of medicine, special clothing, interior textiles, technical goods, etc. We investigated the effect of two different textile woven structures made of 90% polyester with 10% polyamide (PET) and 100% cotton (CO) modified by magnetron sputtering with copper (Cu) on bioactive properties against Gram-positive and Gram-negative bacteria and four viruses and also on the some comfort parameters. PET/Cu and CO/Cu fabrics have strong antibacterial activity against Staphylococcus aureus and Klebsiella pneumonia. CO/Cu fabric has good antiviral activity in relation to vaccinia virus (VACV), herpes simplex virus type 1 (HSV-1) and influenza A virus H1N1 (IFV), while its antiviral activity against mouse coronavirus (MHV) is weak. PET/Cu fabric showed weak antiviral activity against HSV-1 and MHV. Both modified fabrics showed no significant toxicity in comparison to the control medium and pristine fabrics. After Cu sputtering, fabric surfaces became hydrophobic and the value of the surface free energy was over four times lower than for pristine fabrics. The modification improved thermal conductivity and thermal diffusivity, facilitated water vapour transport, and air permeability did not decrease.

This article is focused on the comparison of dyeing, and washing and light fastness properties of conventional and novel perlite-containing polyester woven fabrics via color measurements. All the production processes for the regular and perlite-containing polyester filament yarns were the same. The fabrics were dyed with three medium level energy disperse dyes of different hues in order to observe the shade change caused by the intrinsic yellowness of the perlite-containing fabric. Dyeing and fastness properties of the dyed fabrics were evaluated by their corresponding lightness (L*), chroma (C*), color strength (K/S), and color difference (ΔEab*) results. The perlite-containing fabrics showed similar dyeing and fastness characteristics when compared with the regular fabrics. The perlite-added fabrics were dyed in darker color but had lower chroma values than the regular ones. The perlite-added fabrics also had better fastness results than the regular fabrics when the evaluation was performed in the group itself. Intrinsic yellowness of perlite-added fabrics must be taken into account for any attempt to dye the fabric to a pre-designed shade.

This study presents an eco-friendly protocol for the hydrophilization of polyethylene terephthalate (PET) fabric and the in situ synthesis of ZnO particles. The alkaline medium and reducing agent for ZnO synthesis were prepared as aqueous extracts from wood ash and pomegranate peel, respectively. Due to the hydrophobic nature of the PET fabric, oxygen plasma treatment was included in the process. The influence of plasma treatment in different synthesis steps on the formation of ZnO and consequently on the morphological, colour and ultraviolet (UV) protective properties of the samples was discussed. The study showed that incorporating oxygen plasma treatment before immersing the samples in each solution for the ZnO in situ synthesis (natural alkaline medium of wood ash, zinc salt and natural reducing agent from pomegranate peel) produced PET fabric with the most uniform ZnO layer without visible cracks and the highest UV-blocking ability with a UV protection factor (UPF) of 300+. The colour measurements showed that increasing the number of plasma treatments leads to higher colour strength of the samples. Herein, a novel protocol for the production of protective PET fabrics is presented, which is also an example of a completely environmentally benign textile functionalization process.

The study was focused on investigating the impact of different washing processes (dark shade, medium shade, light shade) on various properties of denim fabric. Two different types of fabrics with twill and dobby weave constructions were produced from cotton, spandex, and polyester yarn, and different types of washing processes were applied. Dimensional stability, tensile strength, tearing strength, EPI and PPI, weight, colorfastness to rubbing, colorfastness to perspiration (acid and alkaline), and colorfastness to water was investigated and comparisons were made statistically between the before washed sample and after washed sample. It is found that the process result shows better tear and tensile strength in case of dark & medium shade wash than light shade wash. On the other hand, weight and EPI & PPI have shown better result for light wash than other wash. Colorfastness to rubbing, Colorfastness to water, and Colorfastness to perspiration (acid and alkaline medium) are similar. The shrinkage% is higher especially in the weft direction of the fabric for light wash than the dark wash.

Full textAbstract:
This study intended to observe the effectiveness of foamed concrete jacketing using fibreglass fabric with the goal to enhance its durability properties. LFC of two densities of 500 kg/m3 and 1000 kg/m3 were cast and tested. The LFC specimens were wrapped with 1 layer, 2 layers and 3 layers of fibreglass fabric. The parameters evaluated were porosity, water absorption, drying shrinkage and ultrasonic pulse velocity. The results revealed that adding fibreglass fabric to LFC decreased its porosity and water absorption for both densities. Fibreglass fabric did more than only prevent cracks; it also reduced the drying shrinkage and increased the ultrasonic pulse velocity of LFC. Three layers of fibreglass fabric offered optimal results for all properties studied. As a result of the fibreglass fabric's ability to prevent moisture evaporation and consequent dimension changes in the confined LFC, drying shrinkage strain was kept least. The use of fibreglass fabric not only prevented water from escaping but also stopped it from penetrating the cement matrix. This preliminary study shows a huge potential to utilise fibreglass fabric as a strengthening medium to improve the durability performance of LFC.

Full textAbstract:
Certain material losses are still tolerated in traditional garment manufacturing process. Only 80% of textile materials purchased by industry companies are used for their main purpose. The other 20% lost in garment cutting process are landfilled, incinerated, reused or recycled. Further technical progress is not able to minimise fabric waste significantly. Possibilities to reduce fabric waste have to be found in the garment designing and development process. Styles from cross directionally striped fabrics have raised material losses because of their specific design and fabric pattern. The 1st experiment with a striped T-shirt showed that fabric waste could be critical due to disconformities of the style design with the fabric pattern. The 2nd experiment showed that it is possible to reduce fabric waste by conforming the length of the style with the fabric pattern. Length tolerance – acceptable slight variations in the length of the style which does not change the design and visual perception of the garment style should be determined by designers and used in industry processing of manufacturing orders. The authors of the article developed methodology to perform the work process in an automated way. Certain manipulations of the design of a garment style directly in its manufacturing process have never been done before, however they could be very effective in producing medium and large manufacturing orders as they would help to reduce post-industrial fabric waste, material consumption, as well as the product cost.

A type of systematic fold made from the fragile medium of paper could be translated to something wearable and durable in fashion is certainly attractive and innovative. Its special characteristic to make three-dimensional shapes from two-dimensional patterns is very fascinating and interesting to make. Fabric waste is the big problem of today and fabric manipulation through systematic folding is the best way to use it. The paper reveals the potential of the fabrics, which could be manipulated using fabric origami and processes of innovative designs for developing fashion product. The study also emphasizes on the reasons why origami was not seen much in the designer’s collection through SWOT analysis. Comprehensive study of industrial waste to convert into useful sustainable fashion product through intervention and exploration into products like accessories and home furnishing is discussed. This expedition will provide an extraordinarily functional yet aesthetical prospect to reach to global market.

The investigation of thermal protective performance of fabrics is highly relevant in order to procure and further develop the firefighters' protective clothing. Therefore, this paper aims at investigating the thermal protective performance of fabrics used in firefighters' clothing under different levels of radiant-heat exposures. For this, properties of a set of thermal protective single- and multi-layered fabrics were measured, and these fabrics were tested under radiant-heat exposures using the Method B of ISO 6942:2002 standard. During the testing, fabrics were exposed to low (10 kW/m2), medium (40 kW/m2), and high (80 kW/m2) intensity radiant-heat exposures; and the heat transfer level (i.e., time required to increase the skin temperature of a wearer/firefighter by certain degrees) through these fabrics were calculated to measure their thermal protective performance. The effects of fabric parameters, structures, properties, and radiant-heat intensities on the protective performance were characterized, and fabric properties that significantly affected the protective performance were statistically identified at different level of radiant-heat exposures. It has been found that weight, thickness, thermal resistance, and evaporative resistance can positively affect the protective performance. Also, the significant fabric properties affecting the protective performance vary for single- and multi-layered fabrics. By using these significant properties, the protective performance of single- and multi-layered fabrics were also separately predicted by mathematical models, i.e., multiple linear regression models and multiple logarithmic regression models. As per the findings of this study, multiple linear regression models can effectively be used to predict the thermal protective performance of fabrics. This study will lead towards building a better understanding and prediction of thermal protective performance of fabrics under radiant-heat exposures.

Full textAbstract:
This study intends to explore the influence of a fabric electrode skin interface filling medium on ECG signals under dynamic and static conditions, so as to be able to better monitor both stable and dynamic ECG signals. In this paper, cotton fabric electrodes were prepared using electroless silver-plated conductive cotton fabric, and then the electrodes were integrated into a physiotherapy-grade elastic bandage to assemble the fabric ECG tape. The electrode impedance tester and the BIOPAC physiological recorder were used to measure the fabric electrode-skin impedance and electrocardiogram under dynamic and static conditions, respectively. Later, the influence of the fabric electrode coated medium on the acquisition effect of an electrocardiogram signal under dynamic and static conditions is discussed. The results show that in the absence of a dielectric reagent coating, the cotton fabric electrode is easily disturbed by external noise which leads to large electrode-skin contact impedance. However, the electrode-skin contact impedance is greatly reduced after coating the fabric electrode with the dielectric reagent. At the same time, after applying the conducive paste coating, the corresponding change curve of the fabric electrode became more stable, and the impedance value was less than 0.005 MΩ·cm2, which meets the standard requirement for textile dry electrode skin impedance. In a state of rest, a clear and stable ECG can be collected regardless of whether the medium reagent is coated or not. However, only after applying the conductive paste can a stable ECG signal be collected under the three motion modes, or can a P wave, QRS wave group, or T wave be clearly distinguished. In addition, there is a high correlation with the disposable gel electrode, which can satisfy the requirements of the long-term monitoring of ECG signals under dynamic conditions.

Full textAbstract:
Multi-structural polymer composites are widely used in the mechanical engineering, automotive, aviation and oil refining industries, as well as in the printing industry as a shock-absorbing deckle on the offset cylinders of printing machines. During offset printing, composites come into contact with inks and washing solutions, the components of which penetrate the material and cause the polymers to swell. This process degrades the print quality, and for this reason the study of its features is relevant. The prerequisites for this work are the study of the fundamental laws of diffusion and sorption of liquids by polymers with different micro- and macro-structures in different physical states and in different forms (e.g., films, sheets, fibers and fabrics). The combination of polymer materials in the composition of multi-structural fabric blankets makes it possible to obtain materials with unique mechanical properties and high resistance to liquid penetrating media and to use them in high-tech processes of multi-color printing with high resolution and color rendering. This article reports for the first time the kinetics and thermodynamics results obtained from the swelling of multi-structural polymeric blankets in solvents used in printing, and the effect of sorption of different polar liquids on the viscoelastic strain under compression during the operation of the damping systems of printing machines. Using mathematical models of activated liquid diffusion in polymers and deformation of a viscoelastic body, the swelling rate constants, solvent diffusion coefficients (the kinetic characteristics of the swelling process) and Flory–Huggins parameters (the thermodynamic characteristics of the interaction of the solvent with the composite) for composite–solvent systems with several chemical composition variants were determined. The elastic modulus and the viscosity coefficient of the composite under liquid saturation were calculated based on the experimental cyclic compression data. The range of change in the compression and restoration times of the polymeric blankets (0.09 s ÷ 0.78 s) was determined. It was shown that the composite swelled to a limited extent in all the studied liquids. All solvents used were thermodynamically poor (χ > 0.5). It has been established that rubber–fabric blankets coated with nitrile rubber are the least resistant to the action of dichloroethane, and that blankets with layers of polyolefins are not resistant to ethyl acetate. Water significantly affects the physicochemical properties of rubber–fabric blankets with a large proportion of cotton fabric layers. The data obtained can serve as a basis for optimizing the compositions of inks and cleaning solutions, as well as a theoretical basis for the thermodynamics of composite–solvent systems.

The performance of ultraviolet (UV) protection, antimicrobial activity, and self-cleaning characteristics of nano titanium dioxide (TiO2) with acrylic binder were assessed on the cotton fabric using pad-dry-cure method. Titanium iso-propoxide was used as precursor with two different mediums of water and ethanol to synthesize nano-sol by sol-gel technique. The synthesized nano-sol-gel was then characterized by using Fourier transform infrared (FTIR) spectroscopy, particle size analyzer (PSA), X-ray powder diffractometry (XRD), and scanning electron microscopy (SEM). The nano TiO2 finished cotton fabrics were tested for ultraviolet protection factor (UPF), antimicrobial activity, self-cleaning action, and physical properties. The wash fastness of TiO2 nano finished cotton fabrics for 5th, 10th, 15th, and 20th washes was assessed and also their ultra protection factor values and the percentage reduction in bacteria in each stage were reported. The self-cleaning activity was assessed for 12 hours, 24 hours, and 48 hours duration by exposing coffee stain on the specimen fabrics to sunlight. The TiO2 nanoparticles had 12 nm when ethanol medium was used and 7 nm for water. The smaller nanoparticles had showed better results regards antimicrobial activity and self-cleaning. In case of UV-protection function it was found that the fabrics treated with 12 nm nanoparticles exhibit higher UPF values than the fabric treated with 7 nm nanoparticles. The durability of the imparted function was in the range of 32–36 washes for antimicrobial activity and UV-protection property.

Abstract Simulation is a modus operandi often used for imitating real-world processes. It involves a system and set of assumptions used for computing a numerical model, from which the outcome is an estimate of the true characteristics of how the system behaves. The intention of this research was to investigate the efficiency of fabric in two-stage cross-flow filtration using linen, crepe-backed satin, burlap and cotton fabric filter media. The results from previous pilot-scale experiments performed showed that linen fabric was the most effective medium at retaining particles. In continuation of this research, the aim of this paper was to utilize Hydrus-1D simulation software to simulate cross-flow filtration with fabric filter medium. This was done to further confirm the efficiency of cross-flow filtration, in particular with linen fabric filter media. Simulation entailed investigating fabric water content versus pressure head; bottom pressure head versus time; fabric water storage versus time; and cumulative infiltration versus time with both single and four layers of fabric filter media. Hydrus-1D simulation was productive since it confirmed that cross-flow filtration with linen fabric filter media has the potential of becoming a pre-filtration step in surface water treatment, further adding to the results obtained from previous pilot-scale experiments.

The weft knitted fabrics including plain, rib, rib and Milano with 31.25tex and 17.86tex wool yarns were taken as research objectives with a view to investigate the influence of fabric textures on pilling performance of wool sweaters. According to the GB/T4802.3-1997, the pilling performances of various samples were tested and studied. The results show that the fabric textures have great influences on pilling performance of wool sweaters. The anti-pilling performance is rib > rib > Milano >plain. The bigger the sinking depth is, the more serious the pilling phenomenon is. With larger liner density yarns, the anti-pilling performance of 1x1 ribs are better; With medium and less liner density yarns, the anti-pilling performance of 2 x 2 ribs are better.

Cotton fabric was dyed with Liyuan Blue FL-RN reactive dye. The dye exhaustion and fixation percentages were calculated for all light, medium and dark shades. The dye shows very good exhaustion and fixation properties. Dyed samples were tested for light fastness property as per international standards. The results indicates the dye has a good light fastness property. The effect of UV absorber was studied in order to improve light fastness property. Cationic UV absorber CANFIX SUN was applied on the dyed cotton fabric by exhaust method. The results show that the color depth was similar after UV absorber treatment. In all the cases the use of UV absorber improved the light fastness of dyed fabrics as compared to untreated dyed samples.

The effect of initial particle fabric on the one-dimensional compression response of Fraser River sand was investigated. One-dimensional compression with lateral stress measurement was carried out on reconstituted Fraser River sand specimens using an instrumented oedometer. Laboratory specimens were reconstituted by air pluviation, tamping, and vibration and were prepared with an initial relative density ranging from medium loose to very dense. For Fraser River sand in one-dimensional compression, air-pluviated specimens yielded the highest values for the coefficient of lateral earth pressure at rest (Ko), tamped specimens produced the lowest Ko values, and vibrated specimens produced intermediate Ko values. The results from the present study demonstrate that specimens resulting from different laboratory reconstitution methods (i.e., different initial particle fabrics) exhibit different one-dimensional compression responses and produce different Ko values. A “fabric factor” was introduced to account for the effect of the initial particle fabric on the measured coefficient of lateral earth pressure at rest. Using the fabric factor, the constant volume friction angle, and the specimen relative density, a new empirical equation defining the coefficient of lateral earth pressure at rest during normally consolidated loading is proposed.

Abstract Cotton fabrics processed in dyes with different mordants and staining pH might alter colors variation and dye absorption. A recent study showed a mixture of Aspergillus and Paecilomyces can be used to dye cotton fabric using five different mordant chemicals, CuSO4.5H2O, FeSO4.7H2O, KAl (SO4)2.12H2O, K2Cr2O7, and MnSO4.H2O, and three distinctive dyeing pH (3, 7, and 11). Both fungi were collectively cultured on mineral salt glucose medium to a stationary stage in dark conditions for four weeks. The RHS color chart was used to determine the color of the filtrate and the spectrum of colors created on dyed materials. The results suggested that the color development and dye absorption of the fabrics were greatly affected by chemical compounds of mordant and the acidity degree of the dyeing process. The pH of the dyeing process has a greater impact on the absorption of fungal dyes by cloth than the mordant. Colors formed on cotton fabric can add colors variation to textile dyeing.

Vacuum infusion experiments with and without distribution medium were carried out in woven E-glass fabric preforms. The experimental set-up was carefully designed to obtain a unidimensional in-plane flow between the inlet and outlet gate, which was combined with through-the-thickness infiltration in the tests carried out with a distribution medium. The variation of the fabric thickness during the infusion experiments was measured by means of digital image correlation, whereas the fluid pressure along the strip was obtained by means of pressure gages. Finally, the in-plane fabric permeability as a function of the fiber volume fraction and the fabric compactability were measured by means of independent tests. The experimental results provided a very detailed picture of the interaction between the fluid infiltration mechanisms and the preform deformation during in-plane and through-the-thickness flow, which is very useful to understand the complex interaction between permeability and compaction during infiltration.

Biopolymer foam was prepared by the reaction of bio-monomer based on vegetable oil with commercial Polymethane Polyphenyl Isocyanate (Modified Polymeric-MDI). The acoustic study of biopolymer foam was examined by impedance tube test according to the ASTM E-1050 and laminated with three types of textile such as polyester, cotton and single knitted jersey. It was revealed that the thicker the fabric the higher the sound absorption coefficient (α) at medium frequency level. The higher the number of layers or thickness of the fabric, the sound absorption through the fabric increases at medium frequency but after the maximum it remains almost unaltered. Three layer of cotton fabric gives maximum α approximately equal to 1 which is 1.104 mm thickness at frequency level of 3000-3500Hz and single knitted jersey gives maximum α at 4thlayer of 2200-2700Hz. Meanwhile , the α of biopolymer foam laminated with polyester fabric approximately equal to 1 at lower frequency level of 2000-3000Hz with lower thickness that is 0.668mm. Polyester fabric with lowest thickness shows better α at lower frequency level due to the structure of the fabric. The relationships among the fiber properties such as fiber density, fiber diameter, and fibrous material layer were considered as a factor that influences the sound absorption property.

Full textAbstract:
This study proposed an extended multi–layer heat transfer model to simulate skin burns of firefighters during firefighting. The proposed model takes into account the effect of fabric movement frequencies, fabric movement amplitudes and human body movement speeds on the heat transfer between the skin and the heat source under low–level radiative exposure. The simulation performance was validated against the simulations in the published literature in terms of the heat transfer in the multi–layer fabric system, skin temperature and skin burns. The results indicated that the fabric periodic movement caused by human body movement decreased the time to skin burns and the skin temperature increased with increasing fabric movement amplitude. During firefighting, the time to 2nd degree burn was 33.3–35.2% shorter at medium human body movement speed than at low and high movement speeds. Furthermore, at low movement speeds, the time to 2nd degree burn was negatively associated with fabric movement amplitude, whereas it was delayed by 12.9–29.8% at the fabric movement amplitude of 2.5 mm at medium and high human body movement speeds. This research provides foundational knowledge for the development of a new generation of firefighters’ protective clothing (FPC) and the assessment of skin burns in firefighters.

Since the plastic anisotropy of the ice single crystal is very high, the effect of a strong (single maximum) fabric on the macroscopic flow law cannot be neglected when simulating the flow of an ice sheet. As this is already a difficult task when using the familiar isotropic power law for ice, the fabric evolution and related macroscopic mechanical behaviour model, to be implemented in such a simulation, must be realistic yet simple enough to achieve results within a reasonable level of complexity, at least as a first step.To this aim, we propose to model polar ice as a transversely isotropic medium; while simplifying the problem, this captures the essential features of the in-situ observed fabrics. The macroscopic mechanical behaviour of the ice polycrystal is obtained by using an orientation distribution function (ODF) for the c axes of the grains, which characterizes the fabric, and a self-consistent scheme, considering each single crystal as transversely isotropic. The evolution of the ODF is described by a conservation equation. In the first stage, this model was run in the simple cases of uniaxial compression and tension along the orthotropy symmetry axis.

Purpose – The purpose of this paper is to elucidate the stress-strain relationships of single-jersey knitted fabrics from uniaxial tensile test followed by deformation behavior using finite element analysis. In order to elaborate the study, high, medium and low tightness knitted fabrics were selected and deformation of fabrics analyzed in course, wales and bias directions (0, 45 and 90 degrees). Design/methodology/approach – This study focussed on uni-axial tensile test of produced test samples using Instron 6021 tester and a development of single-jersey knitted loop model using Auto Desk Inventor software (ADI). The knitted fabric material properties and knitted loop model was imported to ANSYS 12.0 software. Findings – Due to structural changes the tightness and thickness of knitted fabric decreases with increase in loop length The tensile result shows maximum breaking strength at course direction (13.43 kg f/mm2 at 2.7 mm) and maximum extension at wales direction (165.77 kg f/mm2 at 3.3 mm). When the loop length increases, the elongation of fabrics increased and load carrying capacity of fabrics reduced. The Young's modulus, Poisson's ratio and shear modulus of fabrics reduced with increase in loop length. The deformation of fabrics increased with increase in loop length. The increase in loop length gives large amount of structural changes and it is due to slacking or jamming in loops and loosening in dimensions. When comparing the deformation results, the variation within the fabric is higher and structural damage little more when increasing the loop length of the fabric. Originality/value – From ANOVA test, stress and strain distribution was statistically significant among course, wales and bias directions at 95 percent confidence level. The values got from Instron test indicates that testing direction can alter its deformation. In deformation analysis, comparing both experimental and prediction, high amount of structural changes observed in wales direction. The used tetrahedral elements can be used for contact analysis with high accuracy. For non-linear problems, consistent approach was proposed which makes the sense to compare with experimental methods. The proposed model will make possible developments and the preliminary validation tests shows good agreement with experimental data.

Proban® is a multiphase treatment of cotton fabrics based on the formation of pre-condensates using the flame retardant (FR) agent tetrakis (hydroxymethyl) phosphonium salts (THPx). The assessment of the durability of a product demands a preliminary understanding of how relevant it is to extend its lifetime. It is therefore important to minimize the risk of agents impacting: (1) the protection level, (2) shape and dimensions, and (3) additional comfort characteristics of the fabric. This research focused on the impact of washing conditions on the durability of FR properties and appearance of Proban® cotton fabrics, which was systematically arranged through the variation in the chemistry distribution in the Sinner’s circle. The chemical share was varied in laboratory conditions as a simulation of industrial washing based on component dosing, where the temperature, time and mechanical agitation were constant. The washing of cotton fabrics was performed through 10 cycles in four baths containing high alkali components, medium alkali components, high alkali reference detergent and water. The environmental acceptability of washing procedures through effluent analysis was assessed by physico–chemical and organic indicators. The limited oxygen index (LOI), calorimetric parameters (micro combustion calorimetry), thermal stability and evolved gases during thermal decomposition (thermogravimetric analyzer (TGA) coupled with an infrared spectrometer (TG–IR)), surface examination (FE-SEM), spectral characteristics and pH of the aqueous extract of the fabrics before and after 10 washing cycles were selected for proof of durability. The medium alkali bath was confirmed as a washing concept for Proban® cotton fabric through the preservation of FR properties examined through LOI, TGA, TG–IR and MCC parameters and appearance color and low level of fibrillation.
