Influence of condensed spinning method on yarn property北大核心CSCD

In order to explore the effect of condensed spinning method on the yarn properties, the pure cotton yarn with 28. 1, 18. 5 and 14. 7 tex was spun by four kinds of condensed spinning methods based on traditional ring spinning such as four, roller lattice apron compact spinning, compact siro spinning, complete condensed spinning and low torque spinning. The breaking strength, breaking elongation, hairiness and evenness of the pure cotton yarn were tested and analyzed, and the reasons for the influence of four kinds of condensed spinning methods on yarn performance were explored. The experimental results show that the characteristics of the yarn structure by different condensed spinning methods will influence the inner properties of the yarn. The yarn spun with compact siro spinning has the highest strength, the yarn spun with complete condensed spinning has the most beneficial hairiness. The yarn quality of the low torque yarn is better under the effect of the false twister. It has the best evenness, and the yarn spun with compact siro spinning has the lowest total hairiness. © 2018 China Silk Association. All rights reserved.     

Study on spinning process and properties of blended silk/luminous polyester yarn北大核心CSCD

Energy storage luminous polyester fiber is a new functional and environmentally friendly material, whose application in the market is becoming wider and wider. In order to further improve the performance of luminous polyester fiber and broaden its market applicability, luminous polyester staple fiber is blended with silk staple fiber in this study.

Development of leno and lace and comparative analysis of their aesthetic characteristics北大核心CSCD

Leno and lace are two kinds of special fabrics respectively born in the East and the West. Although the origin and weaving method of the fabrics are different, they have many similarities and occupy an important position in the history of textile. Based on the historical documents analysis, one can find that the origin of both fabrics is related to mesh-shaped capture tools and their appearance is featured by perforated appearance. With the aesthetic style of elegance, elaboration and grace, both fabrics symbolize noble identity in the upper class. The aesthetic orientation of leno and lace are usually related to the female, and they are the media for the female to hide or express their right and desire. So, the paper expatiates on cultural connotation of leno and lace from their origin, aesthetic tendency and the female spirit they represent. © 2017 China Silk Association. All rights reserved.

Development and performance analysis on polyester/cotton/hemp blended yarn北大核心

According to two different spinning methods of sirofile spun and ring spun, the paper designed and developed 8 varieties of yarn while each method include four groups of different blending ratio. By testing their performance, the results showed that, the performance of the yarn by siro spinning was relatively stable while the weak section of strength was much less than the ring spun. Meanwhile the yarn hairiness was also better than the ring spun. Along with the increase of the content of hemp, the yarn on strength, evenness, hairiness and yarn faluts such as comprehensive performance of the overall trend was down. When the hemp content increased from 10% to 15%, all aspects of the index of the yarn changed smoothly. And when the hemp content increased to 20%, the comprehensive index of the yarn was still good, but the indicators of the yarn defects became worse.

The preparation and performance of the UHMWPE filament reinforced nonwoven北大核心CSCD

In this paper, the rib fabric woven by ultra high molecular weight polyethylene filament and twisting was directly used as the base fabric. Ultra-high molecular weight polyethylene filament was paved on the rib layer by using the method of multi-pipeline interval conveying, and PET-PA6 bicomponent orange petal fiber spunlace fabric was coated to prevent fiber drift. Then, composite reinforced nonwovens were prepared through spunlace. The experimental results show that: the tensile property, softness and drapability of reinforced nonwovens are between knitted fabric and the common nonwovens, and stab-resistance is better than the two; knitted fabric has greatly improved large elastic stiffness of the ordinary nonwovens; the density of the rib-layer fabric determines the composite effect and the properties of the final product. This product is mainly applied to stab-resistant and bulletproof clothing. Relative to the cascading binding or gluing, spunlaced composite method makes the total thickness of stab-resistant layer reduce 4 mm, and makes the quality decrease by around 1 kg. Besides, the comfort is greatly improved. © 2017 China Silk Association. All rights reserved.
