Abstract: The spinning process of regeneration feather protein /PVA fiber is introduced in this article；The concentration and the solubility temperature of peracetic acid , ultrasonic processing time and the proportion of regeneration feather protein /PVA are selected as analysis objects, the fibers are extracted according to 9 orthogonal expts combinations, and the fiber’s performances are tested. Test schemes are optimized using gray clustering analysis which calculating process is showed with Matlab.

Abstract: Abstract.Based on pretreating linen yarns with acid cellulose,the manufacture technogy of high count linen yarns was investigated.It appeared that the count of linen yarn treated with acid cellulose can be not only increased 6-8,breaking strengthen retain ratio can arrive 88%-99%,but also breaking lengthen change less,comprehensive properties reached equilibrium. Consenquently,the technology may rise the additional price of linen products on the premise of meeting the need of spinning and weaving.It has broad prospective.

Abstract: Recently, concept of overall display and packing have already become an important trend in the development of home textiles industry, and color atmosphere for nice and harmonious space is the key for successful displaying design. Based on the spatial environment and “field” concept, this paper presents the matching rules of spatial colors and some logic color designing methods through in-depth analysis of keynote field, rhythm field, material quality field and pattern field, with which the hard adornments, textiles and decorations could be effectively applied to build an individualized hierarchical and romantic overall display of home textiles.

Abstract: Although point and line grading are widely utilized in garment CAD system, they have a common disadvantage: the increments of cardinal points or line on the to-be-graded patterns have to be calculated and inputted manually. In previous work, basic and fashion pattern are defined and the constant and proportional relation between them are considered to explore computerized grading. In the research, a dart pivotal-transfer relation between basic and fashion pattern is introduced. This paper proposes an automatic grading approach based on dart pivotal-transfers. This approach is illustrated with an example of the front panel of women’s jacket, the cardinal points concerning a dart are rotated around a pivotal-point, the increments of the cardinal points are transformed from that of original ones, and then the X and Y coordinates of the cardinal points in the to-be-graded pattern are gained. The experimental results show the approach is feasible.

Abstract: In this paper, the way and equipment that detects the drafting force of back zone on cotton spinning frame is promoted and designed, on the base of the analysis of draft theory, detected equipment and way of drafting force in existence. Using this way, the drafting force of back zone on spinning frame can be detected on-line effectively. By mechanical analysis way, in the course of drafting the mathematical models of drafting force in back zone and force impressing on sensor are educed; the drafting force is detected on cotton spinning frame utilizing detected equipment of drafting force designed by ourselves. Results indicate: this detected equipment can reflect the size and wave circs of drafting force in back zone, provide a new way of on-line detection of drafting force in back zone on cotton spinning frame and choice drafting process parameters in reason.

Abstract: In this paper, the flat cross-section industry polyester filament was produced. The influences of the spinneret and the spinning parameters on fiber properties and quality were discussed. The product have good cohesion and special luster. It can enhance the surface smoothness of the fabric, which improve the coating effect, wider the application.

Abstract: Underwear is known as the “second skin” of human body. In the historical evolution of garment, its culture develops along with the improvement of human civilization, the transformation of social environment, evolution of culture, and the subsequent moral standards. This paper gives an analysis of underwears of ancient Greece, ancient Rome, the Renaissance and Caesaristic times, and illustrates basic causes of underwear development.

Abstract: Children clothing material is a very important content of children clothing design. Especially for younger children, fabric material selecting is more important than any other design. Fabric material apparel functionality with modeling-style and specific classify application based on fabric material apparel functionality is a most major concern of designers and consumers. This article mainly expounds apparel functionality, modeling-style, classify-application and development trend for children clothing fabric material. Firstly classify children clothing fabric material according to modeling-style, then illustrate all kinds of common fabric material with their application range in children clothing for every category, finally summary development trend of children clothing material in accordance with consumers demand and latest trend of international fabric material.

Abstract: When room space extends from a simple three-dimensional physical space to a four-dimensional spiritual space, when people begin to rise aesthetic appeal to a higher level and emphasize harmony with the environment, the textile works of art at this time were all considered to play one of the most important evolutional roles. Hanging textiles which featured multi-functional made themselves irreplaceable contents in indoor space. From the application and development view of hanging textiles, the article emphasizes on the decorative function and application strategies to look forward to continuously improvement of hanging textiles’ application and design levels in indoor space.

Abstract: Effect of carding machine using gill pin taker-in on polyester yarn hairiness was studied. The hairiness of the yarn processed by carding machine with gill pin taker-in and saw-tooth taker-in respectively, which using three-grade speed was tested by YG172 Yarn Hairiness Tester. The results show that (1) when using gill pin taker-in, it is most advantageous to the reduction of hairiness of 2 mm and above when the taker-in speed is 1290 r/min, while it is most advantageous to the reduction of hairiness of 3 mm and above when the taker-in speed is 820 r/min; (2) when using saw-tooth taker-in, it is most advantageous to the reduction of yarn hairiness when the taker-in speed is 1290 r/min; (3) the hairiness of the yarn processed by gill pin taker-in is more than that processed by saw-tooth taker-in as a whole.
