Abstract: Because of the hydrophobicity of PPS fiber,we used normal pressure air plasma treatment on PPS fiber with the rusult that the PPS fiber was modied and its hydrophilicity was improved effectively.The surface of PPS fiber was etched under the scanning electron microscope (SEM), observation. With the power and the time increasing, the water absorption of PPS fiber increased first and then decreased. However, to the breaking strength of PPS fiber, it was declined basically with the power increasing. Also, it had no great influence for the lasting of time.

Abstract: Pure stainless fiber products have many excellent properties such as high temperature resistance, resistance to corrosion, high efficient filter etc.. Pure stainless fabrics are getting wider range of application in the field of industrial textiles. The property differences between stainless fiber and common textile fiber made the textile processing of stainless yarn difficult. Based on the testing of dynamic friction coefficient, static friction coefficient, breaking strength and breaking elongation, this paper analyzes the main performance characteristic of stainless fiber and the reasons that makes textile processing difficult. Countermeasures for fabric manufacturing are suggested accordingly.

Abstract: This paper is mainly to design the small wind turbine blades to make the wind turbines have automatic braking ability. This study has two main aspects, including choosing the reinforced materials and designing the structure of the blades. According to the fiber hybrid principle, carbon fibers are employed in the main stress area of the blades and other area using glass fiber. At the same time, Aramid fibers are mixed in every area of the blade in order to enhance the tenacity of the blade. The other work is designing the structure of the blade with big main body and small abdomen which twists easily. At the designed wind speed, the power output reaches its rated capacity. Above this wind speed, turbine blades twist to adapt to wind speed and make the rotor solidity of wind turbine declined. While the wind speed changes and becomes small, the torsion of wind turbines’ blades turns back. Thus the wind turbines’ rotor solidity becomes greater and power output increases. So at a certain speed ( 36m/s), the wind turbine can adjusts itself to control the power output keeps on a certain level. And then it brakes by itself.

Abstract: There are various fabric redesign forms of traditional Chinese costume; they are born with Chinese traditional clothing culture, they reflect the social political hierarchy, ethnic cultural characteristics and contain auspicious wishes and symbolic implication.

Abstract: The structure and performance of the axial warp-knitted composite were introduced, including bi-axial and multi-axial organizations. According to the unique structure of this fabric, the mechanical properties and the advantages as a composite reinforcement were compared with regular staple woven fabrics. The advantages of composites reinforced by bi-axial and multi-axial knitted fabrics were discussed and the applications of such advanced materials were briefly presented.

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: By the use of self-developed dynamic heat transfer testing device of the fabric, we have tested the temperature curves of four different materials as cotton, hemp, silk and wool fabrics with time and analyzed the characteristics of the endothermic curves of the fabric. Compared with the conventional plate method we have obtained more information on thermal conduction of the fabric. Furthermore, we have discussed the effects of different materials and different structural parameters on the dynamic thermal conductivity performance of the fabric. It also provides a new way and method for the research and development of the thermal comfort products.

Abstract: The trends and results achieved on application of image processing technique in the textile and garment were reviewed. The basis and principle of application of image technique to the garment pleat evaluation were studied. A blouse wearer trial is conducted so that the images of wrinkles developed on the surface of the blouse with different postures of the wearer were collected. The visual effects of the garment pleats created by various techniques and wearing were analyzed, and methods for extracting pleat images form the surface of the fabric were also introduced. After image processing of the extracted pleats, an evaluation system of garment pleats based on the grey scale was recommended, which included such indexes as the number, depth and width of pleat, and unevenness of pleats. The study took an example of the wrinkles changing in a blouse sleeve when arm lifting, which proved the feasibility of digital expression of wrinkle characteristics by mean s of image technique theoretically and practically. Research results indicated that this evaluation system can truly reflect the form and characteristics of garment pleats．

Abstract: The homemade amino-terminated hyperbranched polymer (HBP-NH₂) was applied as a reducing agent to prepare nano silver. A suitable finishing process was proposed to treat polyester fabrics with nano silver solutions. The distribution and morphology of nano silver on the surface of polyester fiber were observed by SEM. EDS analysis was carried out to investigate element contents of the treated polyester fabrics. The FT-IR spectra, physical mechanical properties and antibacterial activities of nano silver antibacterial polyester fabrics had been tested and compared with common polyester fabrics. The results showed that nano silver particles dispersed uniformly on the surface of the fiber. The treated polyester fabrics attained excellent antibacterial activity and washing durability. The nano silver antibacterial polyester fabrics had an expansive application prospect.
