Abstract: Calcium alginate fibers and nano-silica/calcium alginate blend fibers were prepared by the mean of wet spinning at the same spinning condition. The effect of nano-particles SiO2 on the structure and properties of alginate fibers were studied via many tests. The results showed that the tenacity of blend fibers increased with the growth of the content of SiO2 ranging from 1% to 5%, however, the tenacity of fibers became worse when the content of SiO2 was more than 5%. The effect of SiO2 content on hardness and tribological properties of the calcium alginate fiber was studied. The morphologies of the fibers surfaces were examined with a Scanning Electron Microscope (SEM). The result showed that the surface of blend fibers was still smooth when the consent of SiO2 not up to 7%, the best surface was obtained when SiO2 content was 5%. The incorporation of SiO2 also affected the absorption property of alginate fiber and made it decrease with the increase of SiO2 content. The structures of calcium alginate fibers and nano-silica/calcium alginate blend fibers were studied by infrared spectrum.

Abstract: To improve the elastic recovery of common poly(ester-ether) fibers, especially under lower temperatures, an imide dicarboxylic acid was prepared with trimellitic anhydride and aminobenzoic acid firstly, and then series of poly(ester-ether-imide) block copolymer(CPI) were prepared with this imide dicarboxylic acid, terephthalic acid, 1,4-butanediol and polytetrahydrofuran glycol .etc. The stuctures and properties were investigated by FT-IR spectra, differential scanning calorimetry(DSC) and capillary Ubbelohde. It was found that the Tm of the polymer was about 140°C and the intrinsic viscosity was 0.7~0.9dL/g. The CPI copolymers were melting spinning. The draw ratio and test temperature effects to the fibers' elastic recovery were studied. The results showed that stretching is beneficial to the improvement of the elastic recovery; the modified fibers' delayed elastic recovery was above 92% at 28°C and over 95% at lower temperatures of 5°C and -10°C, which is a great improvement to the common poly(ester-ether) fibers'.

Abstract: Added sarcandra glabra extracts into cellulose viscose solution, make the two blends together to spin, and get functional viscose fiber with the nature antibacterial function. The test result shows that mixed sarcandra glabra extracts has no bad effect on the basic mechanical properties of the viscose fiber and the viscose fiber has the good antibacterial performance.

Abstract: This text takes the spun-laced non-woven fabric weaving machinery as an illustration, introduces the Textile machinery synchro-control system based on Siemens S7-300 PLC and Textile machinery by Siemens plc and DANFROSS Inverter.

Abstract: In this study, a 85/15 AN/MA copolymer (acrylonitrile – methylacrylate copolymer with feed ratio of 85/15 mol%) was synthesized by emulsion polymerization at 60 °C, and then the copolymer was used to produce hollow fiber (abbreviated as PAN hollow fiber )by melt spinning using a single screw extruder machine. The PAN hollow fiber was characterized by using Scanning Electron Microscope (SEM), Thermo-gravimetric Analysis (TGA) and Differential Scanning Calorimetry (DSC). The hollow fiber of melt-spinning PAN with high hollow rate of 51.1% has a homogeneous wall and regular section. The hollow fiber is potentially used as raw materials to fabricate heat preservation fabric for comfort clothing.

Abstract: This research studies the effect of penetrant, formic acid, sodium bicarbonate and steaming time on the rubbing fastness and K/S value of printed leather. The results show that the optimum concentration of sodium bicarbonate is 10 g/L in the first step of the leather pre-treatment. The optimum concentration of penetrant is 20g/L and the PH of pretreatment solution is 3 in the second step of the pre-treatment. The wet and dry rubbing fastness reaches grade 3 and 4-5. The pattern on the printed leather is clear and fine.

Abstract: To better understand and perform of using pearl fiber characteristics, improve the development of targeted clothing, based on the fabric common performance such as comfort, wrinkle-free performance and safety in this article, to carry out the performance testing for 65/35 two-ply cotton / pearl plain jacquard imitating silk high-grade wrinkle-free fabric, in which mainly test the fabric moisture absorption, water vapor permeability, air permeability, anti-crease, security. Then concluded that the wrinkle-free performance of the 65/35 two-ply cotton / pearl plain jacquard imitating silk high-grade fabric is good, and the fabric has good wearability and value.

Abstract: In recent decades, different concepts in quality management in textile industries have been introduced. Quality is a highly significant concept and also is the most basic challenge for textile industries. What we called controlling in the past, now has been replaced by “quality control”. Among these strategies, production and noble thought in order to recognize and remove not valuable resources on one hand, and six sigma in order to recognize and remove error elements in the process on the other hand, have developed the textile factories. Six sigma and noble methodology are two very strong strategies in for textile companies to reach success and have high quality products. Noble methodology causes a cut in the expenses through optimizing the process whereas six sigma is related to the customers’ expectations or needs. It also improves quality through measuring and controlling the deficits. This study is an attempt to improve textile products through two views: six sigma and noble methodology. Each of them this objective by its own .

Abstract: Many enterprises attribute their success to the construction of quick response (QR) mode. The (QR) mode in the fashion industry embraces the digitization of the products, the management of sale and production, and the cooperation with the external suppliers. With cases analysis on different approaches to constructing the (QR) mode in fashion industry, this article points out the necessity to make an overall procedure and organization revision for the purpose of building a (QR) mode, to which developing the products on an effective basis, making an accurate purchase, proceeding a flexible production are essential, and the necessity of full application of external resources, such as modern logistics to quicken the enterprises’ response and improve their competitiveness.

Abstract: Preparation of uniaxially aligned nanofibers by electrospinning has been a new research hot spot in recent years. Well-aligned polysulfonamide (PSA) nanofibers with the diameter of 200nm were successfully prepared by magnetic electrospinning with the distance between the two magnets of 8cm. The key to the success of this method was the use of a collector composed of two permanent magnets to suffer an applied magnetic field. And the mechanism of magnetic electrospinning was also discussed in detail.
