Abstract: In order to develop the multi-functional high-end apparel fabrics, the paper used materials, organization, patterns and colors to achieve a reasonable design to make cool fabrics, and when using Honeycomb UV fiber/ Tencel/ honeycomb jade fiber (50/30/20) blended yarn and machine warp density is 40 root/cm, weft density is 33 root/cm, fabrics havemost cool nature. This project combined with today's Fabric trends and used a sense of cool colors such as green and blue, has designed cool multifunctional composite high-end fabrics and showed the appearance of cool fabrics more comprehensively in the form of clothing simulation results.

Abstract: In order to study the curing characteristics of common resins including bisphenol-A epoxy vinyl ester resin, phenolic epoxy vinyl ester resin and unsaturated polyester resin, the curing time of three resins was tested using cobalt naphthenate as accelerator and methyl ethyl ketone peroxide as curing agent. The results showed that the resin curing time reduces with the experimental temperature rising; in order to control the curing time at about 25 minutes when the experimental temperature is 23°C, the curing agent adding proportion of bisphenol-A epoxy vinyl ester resin, unsaturated polyester resin and phenolic epoxy vinyl ester resin are respective about 0.7%, 0.5% and 1.8%. The composites made by bisphenol-A epoxy vinyl ester resin have excellent tensile strength and composites made by phenolic epoxy vinyl ester resin have best bending strength.

Abstract: To study the influence of structure parameters on moisture permeability of fabric woven by fine pp fiber with star section, nine fabrics with different structure and tightness had been woven for experiment, and a moisture permeability test with moisture absorbtion method was performed and compared for these fabrics. Some conclusions are obtained: the moisture permeability showed direct correlation with fabric texture and tightness. It will be improved as the the float of weave get longer. Moreover it will decline with the increasing of fabric tightness and showed significant correlation with Polynomial function when the results fitted with it.

Abstract: In this paper, the low-velocity impact properties of the 3D woven composites were tested. Through the study on the relationship of absorbed energy and material structure, the impact resistance of the composites has been discussed. The research results show that the low-velocity impact resistance of quasi-orthogonal composites is the best, the low-velocity impact resistance of orthogonal composites is the worst and angle tangled of interlayer joint composites stand somewhere between the two. Adding quasi-orthogonal unit into the structure, the low-velocity impact property of the composites can be enhanced efficiently. On the other hand, if the unit distribution of the enforced fabric is changed, the break time and break point will be changed. But the effect on the total absorbed energy is not obvious.

Abstract: In order to further study anti-bacterial properties and the influence of different content of photocatalyst fibers on the anti-bacterial properties, the photocatalyst and bamboo fiber were blended with different proportions and series of fabric samples were selected in the experiments. Shock method was used for the fabric samples which the anti-bacterial properties were tested and analyzed. Test results showed that, the inhibition of bacterial function is better for textiles woven with fibers of photocatalyst modification. When the fiber content of photocatalyst is 40% in the fabric, the inhibitory rate of the fabric can be reached to 86%, and can provide a theoretical basis for the future development of anti-bacterial fabrics.

Abstract: In order to study on the anti-electromagnetic radiation performance of fabrics with silver-plated fibers, five sets of samples with polyester DTY and silver-plated nylon filament were manufactured for the experiment. The anti-electromagnetic radiation property of fabrics was tested with Flange coaxial method. The influence of different silver-plated fiber contents on the anti-electromagnetic radiation performance of fabrics was analyzed in this paper. The experimental results show that when silver-plated fibers are distributed by a network, anti-electromagnetic radiation performance of fabrics is better than that the silver-plated fibers are distributed only along the warp in fabrics. Meanwhile, the anti-electromagnetic radiation performance of fabrics improves as the increasing of the silver-plated fibers content. The anti-electromagnetic radiation performance of fabrics increases slowly when silver-plated fibers content is from 40% to 80%. The shielding effectiveness of fabrics for 10MHz~1000MHz electromagnetic waves increases not obviously when silver-plated fibers content is more than 80%, but that for 3000MHz is still rising. The anti-electromagnetic radiation performance of fabrics is the best when silver-plated fibers content reaches to 100%.

Abstract: For fabrics, the diversification and superior of the properties and the styles can be achieved by blending fibers. To keep up with the demand of the market, PTT, PLA and Rayon were selected as the materials and 10 kinds of PTT/PLA/Rayon blended fabrics with different fiber content were designed and woven. And then the wearabilities of the fabrics were tested respectively. At last, fuzzy evaluation wad used to discuss the affection of the blended ratio on the fabric’s wearability. The results show that various kinds of wearabilities of the fabric are the best when the blending ratio is PTT/ PLA/Rayon 40/30/30.

Abstract: In order to study the wearability of multi-component blended fabrics, there are 9 kinds of fabrics which belong to A, B and C three series were woven. They were blended with different proportions e.g. PTT, PLA, Cooldry, triangular shaped polyester yarn, cotton, hemp, viscose, conductive filament, and so on. Anti-pilling property, crease recovery, drapability, moisture transmission and air permeability of the fabrics were tested and analyzed. From the test results, following conclusions can be gotten. 1) The anti-pilling property is good for fabrics with tighter weave construction; 2) The crease recovery is good for fabrics with smaller weft density; 3) The moisture permeability is good for fabrics with smaller tightness; 4) The crease resistance, drapability, moisture permeability and air permeability of the fabrics can be improved by looser weave construction and smaller binding point.
