Abstract: Kapok fiber is getting more and more extensive attention in research and application because of its excellent natural characteristics such as its lightness, super warmth, anti-bacterial, anti-mite etc. in recent years. On the other hand, the features of short fiber length, low breaking elongation, water repellency and oil absorptive in surface, make it difficult when spinning and dyeing, and hinder its application and popularization in the field of textiles. This paper discusses the fiber structure, physical and chemical properties, spinning and dyeing process performance of kapok fiber, points out that it is up to 80% ~ 90% fiber hollowness, so very lower fiber apparent density as only 0.29g/cm³, water repellency, anti-bacterial, anti-mite, have potentially wide application. However its spinning and dyeing performance is poor, the process cost is higher and the yarn quality needs to be improved. In this paper, the main types of kapok fiber products and the reason that restricting the fiber development and application to consumption market are analyzed. Finally, the paper puts forward the countermeasures concerning the further utilization with kapok fiber characteristics, and further expanding the development as a new generation of green ecological kapok textiles in the future.

Abstract: The most important situation of textile companies is to design products which much more meeting the consumers feeling. In this paper, 4 kinds of silk fabrics were taken as the objects, 4 physiological targets were used such as electromyography (EMG), skin resistance (SC), skin temperature (ST), and respiration (Resp) from tactile and visual cognition. The aim of this research is to find out the physiological evidence of consumers in tactile and visual for textile. As the result shown that, accompanied by touch and watch, skin resistance and electromyography have obvious regularity undulation, and there were large discrepancy in each objects, however, skin temperature and respiration had little correlation. In a word, physiological indicators can be used as silk fabrics cognitive quantitative evaluation basis in tactile and visual more intuitively and conveniently.

Abstract: This paper presents an approach to identify the fabric of styles by wave of friction. First, the friction waves of typical cotton, wool, silk and hemp styled fabrics are collected under controlled conditions with a self-made device. In allusion to the non-stationary and attenuation of the signals, differences based on scopes are proposed to represent the features of wave signal in various aspects, which forms into a feature impulse. Pairwise comparisons are made among feature impulses of the four typical fabrics and it is revealed that their features are unfolded gradually from microcosmic to macrocosmic. Then, considerable amount of fabrics of each style are included to extract feature impulses, which constructed a feature library. Finally, the indeterminate fabrics are identified by the feature library, and the results are reflected in a ocular way into a discrimination chart.

Abstract: With the rapid development of the knowledge economy and the information society, the importance of some elements of the traditional industry clusters have changed, which makes this cluster model adapt to the rapidly changing market toughly. Therefore, this cluster model needed to be transformed into the "modern industrial cluster" which based on the information basic service platform and integrated industrial chain. This article regards Shanghai Dragon (Group) Corporation (SDC) as a case and studies its current situation and problems in depth, then makes a timely strategy of the modern textile industry cluster which based on the features of "home" from the actual situation of the textile and garment industry. Also, it aims at improving the overall competitiveness of the SDC and thus benefits the affiliated enterprises from the actual operation in the development platform of technology, sales channels and co-branded.

Abstract: The traditional woven fabric's shortage of the method of test and evaluation was introduced, and the improvement programs were proposed by experiment. The influence of the objective errors of sample cutting, the inconsistency of the directions of cutting and fabric, the difference of the opposite sides on the test and evaluation was also analyzed. The improvement programs including increasing the sample number and expanding the evaluation index were drawn up and testified by being compared with the actual result. The experiment result confirmed that the veracity of the test result could be improved by cutting accurately and increasing the sample number. It was more reasonable to choose the sum of warp, broad and diagonal crease recovery angles as the assessment index for the woven fabric's elasticity on the wrinkle resistance. For the fabric which has different organization on both sides, the elasticity on the wrinkle resistance of the both sides should be tested separately.

Abstract: Self-lubricating bearings liner is a fabric that can extend the period of use of spherical plain bearing. In this paper, the structural parameter of self-lubricating bearings liner was discussed. Taking MPIA as warp, respectively the MPIA/PTFE twisting yarn and PET/PTFE twisting yarn as weft, we obtained 12 fabrics by changing the weft surface effect of fabric structure, linear density and twist of weft. Then, the wear resistance and frictional property of the fabrics were tested, and the relationship between the factors was analyzed. The data shows that the wear resistance and frictional properties of the fabric with change of different factors. In comprehensive, more suitable self-lubricating bearings liner can be made by selecting MPIA and MPIA/PTFE twisting yarn intertwined, increasing weft surface effect, with moderate weft twist factor, and increasing weft linear density.

Abstract: Shanghai textile holding group (Shangtex for short) is one of the leading enterprises in the Shanghai textile industry ,as well as the largest state-owned enterprise, it plays a central role as a "bellwether" in the whole industry. In this paper , the study on the leading role of Shangtex suggests that it is an inevitable choice to make Shangtex as the leader to guide the development of cluster strategy if Shanghai textile clothing industry wants to tag on the changing times,submit to the trend of industries development, go on the routing of industrial cluster, and enhance the overall competitiveness. so that it can drive the common development of the whole Shanghai textile clothing industry. secondly, through the quantitative evaluation and status analysis about the degree of cluster development of the Shangtex, we make further improvement strategy for cluster development of Shangtex.

Abstract: Research of the processing technology to make the weft be curved shape in woven fabrics. We demonstrate the feasibility of using the tension method, the beating-up method, the yarn method to product weft-curved fabrics. Through weaving samples in laboratory, we discussed the actual effect and existing problems of the three methods, summarized the technical methods that we should choose to make weft-curved fabrics be in industrialized production and the new ideas to develop weft-curved fabrics. We believe: If we use the big-belly yarns containing PVA fibers to make weft-curved fabrics, its effect is the best and symbiotic defects are the most slightly. At the same time, with the low technical difficulty and high production efficiency, it should be the preferred technical approach to develop weft-curved fabrics. The technology to develop weft-curved fabrics is more suitable for the development of new staple products and yarn-dyed striped grid, new jacquard products.

Abstract: Typical woven fabrics for bedding were selected from the market in this paper. Based on test and analysis results of the structural parameters, the relevant performance indicators were measured in consideration of mechanical properties,comfort and style of fabrics, and the test data were systematically integrated and the relevant quantitative data were ultimately obtained. Meanwhile, Fabric Assurance Tester was used to determine the style of the fabrics and tested indicators were chosen, following with normalized statistics and processing. In addition, SPSS software was applied for the correlation analysis between fabric properties and structural parameters through the correlation and partial correlation analysis.According to the results of correlation coefficient,partial correlation coefficient, the paper revealed the intrinsic link between the fabric’s structural parameters and its properties. As to the main factors of the structural parameters which greatly affect the performance of the fabrics, they will provide scientific evidence for the design and development of fabric.

Abstract: The effect of the polypropylene fabric morphology on the grafting copolymerization of methacrylics in the aqueous solution under ultraviolet irradiation was investigated. The infrared spectra and the scanning electron microscopy images verified the successful grafting copolymerization of the two monomers, glycidyl methacrylate (GMA) and Hydroxyethyl methacrylate (HEMA), onto the three fabrics, the spunbonded polypropylene nonwovens (SB), the spunlaid-meltblown-spunlaid polypropylene nonwovens (SMS), and the polypropylene monofilament plain fabrics (MPF). The results showed that, the grafting degrees of the two monomers increase and then tend constant with irradiation time, while those increase with the increase of the monomer concentrations for all the fabrics. The tight texture structure and the well-stretched monofilament surfaces of the MPF fabrics retard the grafting to a great extent. The inner fluffy meltblown layer of SMS nonwovens favors the grafting as compared with the SB nonwovens.
