The varied-level fibril packing models in the multiply layers of a cotton fiber were widely concerned previously, and different varied-level fibril models were brought forward. This paper mainly concerned on the fractal characteristics of secondary wall S2 of a cotton fiber, assumed that S2 is composed of three grade fractal structures with the four level fibrils respectively, and adopted three fibril packing models, i.e.—round, intermix and elliptic styles. Their radius, fractal dimensions and crystallinity were calculated and compared, and then, modified the hypotheses. Models have been modified and examined according to the error. The results showed that fractal dimensions of the three different level fibril structures are 1.6575, 1.647 and 1.732 respectively, the crystallinity of improved fibril bundle is 64.7% and closed to its measured result 66.7% of cotton fiber.

In order to realize the regeneration and application of waste wool、improve the recovery rate of macromolecular keratin and extend the application fields of keratin resources, NaHSO3/LiBr/SDS dissolution system was used to deal with waste wool and study on preparation of non-toxic、high dissolving rate and high molecular weight of stable keratin solution. .By means of the single factor contrast tests of component use levels、pH value、reaction temperature and reaction time, the optimum reaction conditions were obtained through investigating the texting indexes including wool dissolution rate and large molecular weight keratin extraction rate. Results showed that: the keratin solution could be obtained at 94 % wool dissolution rate and 50.2% keratin extraction rate under the optimal condition when NaHSO3 concentration was 0.5 mol/L, LiBr concentration was 0.1 mol/L, SDS concentration was 0.02 mol/L, reaction temperature was 90℃,reaction time was 4 hours , pH value was 12. Although the reduction system without the addition of LiBr remained at a high dissolution rate, the low extraction rate only presented 30%. IR spectra showed that the extracted keratin from solution system with the addition of LiBr was dominated a-helical conformation. It can be used in textile materials and development of new functional fibers.

In this paper, PP/CB films with 2.2wt% carbon black(CB) content and 3.3wt% CB content were prepared via Melt Blending-Masterbatch Dilution Method, assisted by high-efficiency dynamic mixer. A potential on-line measurement new method, color difference, was taken to characterize the dispersion CB particles in polypropylene matrix. The standard color difference of films is less than 1.5NBS, while the color difference between every two samples is less than 1NBS. The color difference between every two samples reflects actual difference between than standard color difference, and it can also exclude abnormal samples. The color difference of films with 3.3wt% CB content is less than that of films with 2.2wt% CB content. Too high CB content masks the dispersion of CB on color difference. The testing method of skewness-kurtosis was employed to test normal distribution of color difference values and its significance. It shows that color difference values approximately follow normal distribution. Given significance level α=0.05, the mean value of color difference is less than 1NBS and there is no significant difference between films, which indicates that CB particles achieve the desired dispersion state in polymeric matrix. The color difference values and gray series exist the following relationship: when CD≤3.4, GS=5-CD/1.7；when CD＞3.4, GS=5-lg(CD/0.85)/lg2. After calculating, the mean color difference of films is 0.54NBS and the gray series is 4.68, which shows no color difference between films and a good mixing state between CB particles and polymeric matrix.

Co-woven-knitted (CWK) fabric is produced using glass filaments as inserted yarns and high tenacity polyester as stitch yarn. Tensile tests are carried out in the wale and course directions. The mechanical properties of the fabric are investigated by analyzing the stress-strain curves. The results revealed that woven structure bear high load in low elongation to failure, and then, the knitted structure commits the low load in high elongation until it damage. Interweaving between warp and weft yarns leads to large buckling of them and low strength utilization for warp and weft yarns. Intermeshing of stitch yarn also leads to low strength utilization for stitch yarn.

In order to improve the accuracy of defects classification, a texture feature selection method was proposed based on binary partial swarm optimization (BPSO). The first step of this method is collecting and preprocessing defect images, then extracting the texture features to form candidate features. Then the BPSO was applied to select optimal features and redundant features from the candidate features. Finally, the support vector machine (SVM) is trained with these three features to classify defects, respectively. The experiments show that the classification accuracy of optimal features is greatly better than the other two features; demonstrating that the method is feasible and effective for feature selection of fabric defects.

In order to reveal the relationship between sizing performance and molecular structure of water-soluble polyurethane used as warp sizing agents, a series of water-soluble polyurethane were synthesized using 2,4-toluene diisocyanate, polypropylene glycol, dimethylol propionic acid and 1,4-butanediol as monomers. The structure was characterized by 1H NMR. Through varying the molar contents of the 2,4-toluene diisocyanate, polypropylene glycol, dimethylol propionic acid and 1,4-butanediol, the solubility, adhesion-to-fibers, and film behaviors of the polyurethane were investigated for determining its reasonable structure. The results demonstrate that the solubility of the polyurethane was enhanced with the increase in the content of dimethylol propionic acid. The adhesion and film strength increase with the decrease in molar content of polypropylene glycol. However, the decrease gradually damaged abrasion resistance of sizing film. Based on the performances considered, the polyurethane with better performances could be prepared by adopting a monomer formulation in which the proportion of 2,4-toluene diisocyanate, polypropylene glycol, dimethylol propionic acid and 1,4-butanediol were 1.05/0.3/0.3/0.4.

Nanometer-sized titanium doixide films prepared by hydrothermal precipitation method were first immobilized on the surface of polyamide fibre using tetrabutyl titanate, and then dyed with Remazol Brillant Blue R-X. Scanning electron microscope (SEM), X-ray diffraction (XRD), infrared spectroscopy (IR), differential scanning calorimetry (DSC) and thermal gravimetric (TG) analyses were used to characterize the morphology, crystalline phase, chemical structure and thermal stability of titanium doixide coated fibre. The properties of reflectance spectrum, tensile, water absorption, K/S value and color fastness for polyamide fabric were measured. It was observed that when polyamide fabric was treated with tetrabutyl titanate aqueous solution at 120 ℃ for 5 h, pure anatase nanocrystaline titanium doixide particles of average size 10 nm were synthesized, and adhered onto fibre surface by means of physical mode. As compared with the untreated fabric, the onset decomposition temperature of TiO2-coated fabric decreased. The capability of against ultraviolet radiation was improved. The breaking load and tensile strain in warp and weft directions increased to some extent due to the shrinkage of fabric size. The water absorption changed a little. The color yield (K/S value) decreased slightly, but then increased after being washed with water. The color fastnesses to rubbing did not change. The K/S values of TiO2-coated fabric irradiated by ultraviolet ray at different time decreased slowly compared with that of untreated one.

Due to the complexity of apparel supply chain and the characteristics of apparel suppliers, the processing costs and risks of apparel enterprises are difficult to predict accurately. So, a decision-making optimization model of apparel suppliers considering the risk may help enterprises to select the correct suppliers. The apparel suppliers could be divided to raw material suppliers and garment processing factories. Then, according to the mean-variance theory, the expected cost and portfolio risk of suppliers were described. Further more, with the complete constraints, the decision-making optimization model was established which indentified minimizing the costs and risks of suppliers as the optimized object. The risk aversion coefficient was proposed by Markowitz’s risk price theory. This method combining the utility function reflected the risk preferences of decision makers objectively. In the end, the practical examples demonstrated the effectiveness of the model.
