For the identification of cashmere, the statistical regularities of scale pattern genetic code under optical microscope are studied. These results show that fiber diameter is even and its coefficient of variation smaller than that of other scale pattern gene codes. Among all scale pattern gene codes, the optimal fitting of scale rectangle factor follows normal distribution with a correlation higher than 0.96 and that of all other shape parameters follow lognormal distribution with a correlation higher than 0.99. Further comparisons show that among all scale pattern gene codes, the dispersion of relative shape parameters is smaller than that of absolute shape parameters. The dispersion in scale rectangle factor is smallest and largest in scale area. More scale look like a square or narrow rectangle. These statistical characteristics give us a reference in finding an optimal gene group for the identification of cashmere and also lay a theoretical foundation in developing the identification principal of cashmere.

In order to research notch sensitivity of flexible warp knitting metal mesh, its unilateral and bilateral notch are preset, and then, the warp direction tensile are tested at the speed of 20mm/min. The destruction and tensile load-elongation curve of notched samples are analyzed. The notch tensile force (Fnotch), the threshold force (Fthreshold) and notch strength ratio (RNS) under the notch size ratio (a/W) are compared and analyzed. Experiment and analysis results show that preset notch significantly degrade the tensile mechanical properties of the metal mesh material; Fnotch and Fthreshold are both greater in bilateral notched specimens than in single-sided notched specimens in the case of the same incision length. Relative to bilateral incision, flexible warp knitting metal mesh is more sensitive to unilateral incision. This is because the "girdling" phenomenon of the stretching process which make the samples of unilateral incisions to be forced only in one side, while the specimens of bilateral notch can bear force from both sides.

The cotton fabric was irradiated for different time under UV to investigate the changes of structure and properties of the irradiated cotton fiber when the power density of UV was 100w/cm. And the surface morphology, degree of polymerization, mechanical properties, thermal stability and whiteness of cotton fabric were discussed. The results indicated that the increase of irradiation time cloud lead to aggravation of injuries in structure and properties of the cotton fiber. When the cotton fabric was irradiated for 30s under UV, surface of the cotton fiber was etched and surface roughness of fiber was increased. The temperature at the largest weight loss rate of the irradiated cotton fiber was decreased by 8oC and during initial stage of weightlessness weight loss rate was slightly increased, which suggested that thermal stability was reduced. The whiteness of cotton fabric was dropped by 7% and cotton fabric became yellow. The covalent bonds C―C, C―O of cellulose were opened and breaking strength in warp and weft directions of the cotton fabric were reduced by 21% and 10%, respectively. The degree of polymerization of the cotton fiber was varied from 692 to 140. And it could be predicted that variation of structure and properties of cotton fiber would be enhanced with the continuous increase of irradiation time.

Abstract. Surface modified wool fabrics were obtained by chitosan sulfamic acid/TiO2 sol treatment. FT-IR, SEM, thermogravimetric analysis (TGA) was used to characterize the structure of modified wool fabrics. It indicates bond is formed in the modified wool through IR spectra. That treated wool fibers had more smooth surface appearance showed the presence of chitosan sulfamic acid /TiO2 film deposited onto surface of wool fibers. TGA demonstrates that the modified wool exhibits better thermal stability. Based on single factor experiment, the influence of dyeing conditions on the color strength (K/S value) of modified wool fabrics with weak acid red B dyeing were studied and compared to untreated wool. As a result, it can be concluded that the weak acid red B dyeing properties of chitosan-sulfamic acid /TiO2 modified wool were better than untreated wool at 6% dye concentration,pH5.2,70℃and dyeing time 1h. Kinetic study showed the experimental data were fitted with second-order kinetics. Further, low temperature dyeing of wool fabrics with chitosan-sulfamic acid tetrabutyl titanate (TBT) is safe, so the results obtained are quite promising as a basis for possible future industrial application.

Abstract：Under exposure to flash fire, the surface temperature of the thermal protective clothing rises gradually during the exposure, and the heat transfer to human body might cause damage to skin. In this paper, the flame manikin system and the thermal infrared camera were used to capture the surface temperature of 10 sets of protective clothing and manikin after flame exposure. The results showed that the temperature of clothing was very high during the initial stage of cooling period, and the heat transferred to the body, resulting in the increase of the skin temperature for about 10 seconds, the rising rates of the arms and the legs are higher than those of the bodies. Decreasing of burning time, application of slight fabric reduce the tendency of rising surface temperature, but increase of burning time, tight garment will increase the tendency of rising surface temperature. A new parameter―the efficiency index of the heat dissipation about the flame manikin (γ) is introduced to attribute, contrast and compare the heat dissipation after the fire exposure.

According to the type of detected fabrics as well as the research approaches adopted in recent years, this paper briefly summarizes new fabric defect detection system’s application and progress on computer vision and image processing. The theoretical and practical significance are analyzed firstly in the research area of fabric defect detection. We give the two crucial frameworks of a fabric defect detection system: visual image acquisition and defect image detection. Considering that white fabric and yarn-dyed fabric are especially urgent for detection, we lay emphasis on the discussion of the various novel detection methods involved in the two kinds of fabrics, as well as their application effects and deficiencies. Conclusion is lastly reached and some suggestions are put forward for the development of fabric defect detection in the future.
