As an important textile material, the cotton’s security is drawing more and more attention. In this paper, we focus on the photodegradation and alkali hydrolysis products as well as the dynamics hydrolysis-reduction of diuron, a long half-life herbicide common used in cotton product. High Performance Liquid Chromatography (HPLC) was employed for analyzing all the diuron solutions extracted from cotton fiber and photodegradation sample. The result showed that diuron can be completely removed from cotton fiber in about 40 minutes in common scouring condition and the degradation products of diuron in photolysis and scouring process were the same compound: 3, 4 - dichloroaniline. It was also concluded that HPLC can effectively detect diuron residues on cotton fiber with a good repeatability and can meets standard pesticide testing requirements.

For the identification for cashmere and fine wool based scale pattern gene codes, the accuracy was studied. These researches show that though the same gene codes of cashmere and fine wool follow the same distribution, the numerical characteristics are different. The numerical characteristics of gene codes show that the scale of cashmere is more like a square or narrow rectangle and that of fine wool more like a wide rectangle. Among scale pattern gene codes, the distribution curves of scale area, perimeter and rectangle factor between two types of fiber are serious overlap, which imply that the three gene codes can’t be used to distinguish cashmere from fine wool. Except for that, the distribution curves of other scale pattern gene codes are partial overlap. So the different identification standard can be developed on the basis of minimum recognition errors for each scale pattern gene code and the maximum recognition probability of 88.8% for cashmere and 92% for fine wool can be got. These results provide a theoretical basis for the finding of optimal gene group for distinguish cashmere from fine wool.

The colored luminous fiber is a new kind of functional textile material, which gives off emissive color light in darkness. Under colored pigment and luminescence material influence, there is a certain deviation in the color and emissive color of luminous fiber, which affects human visual perception and feelings given by colored luminous fiber. By testing color performance and emissive light color performance, this paper discusses the relationship between the color and emissive light color. The results showed that the color properties of colored luminous fiber showed in lighting are similar to that of ordinary fiber. The hues are great differences between the colors. The absorption of light is enhanced with the increased K/S value, which results in deeper color. In darkness, emissive light color of colored luminous fiber is mixed with yellow light and green light. There was no obvious difference among the hues of emissive light color, but luminous intensities are different.

One-step oxidation-reduction reaction was adopted to prepare polyaniline/Ag composite conductive fabric. The composite conductive fabric was characterized by surface morphology, chemical composition and thermo stability using SEM, FT-IR, XPS and TGA, respectively. The conductive performance and mechanical properties of the polyaniline/Ag composite conductive fabric were evaluated. The influence of washing times on its conductive properties was also investigated. The results revealed that one-step oxidation-reduction reaction can form polyaniline/Ag composite coating on the surface of polyester fabric. The composite conductive fabric has a higher thermal decomposition temperature and better conductive than polyaniline coated fabric, while it retains the basic mechanical properties of the polyester fabric. The conductivity of composite fabric was still better than that of polyaniline coated fabric, after 50 times washing.

As it is influenced by inspection environment and the characteristics of defect, the traditional detection methods are difficult to meet the requirements of defect dynamic detection. A new method based on visual saliency mechanism is presented in this paper. First of all, characteristic pattern is obtained through extracting the features of acquired image. Secondly, the characteristic sub-images are formed by wavelet multilevel decomposition of the characteristic pattern. On this basis, the center-surround difference operation is used to construct the characteristic difference sub-image. Then, through fusing these characteristic difference sub-images, the salient image is formed. Finally, extracting the region of interest use the threshold method, and then segmenting the defect targets use the region growing method. Experimental results show that this method can detect plain weave fabric defect information, and has strong anti-jamming ability.

We propose an improved algorithm to rapidly set the seaming information in the garment by means of the selected segments in the 3D space. According to our algorithm, the low efficiency brought by previous methods can be improved and the problem of the seaming information’s cluttered display in the 2D background can be solved. Firstly, we build the garment hierarchical model to select the silhouette segments. Secondly, to decrease the human-computer interaction cost and improve the efficiency when setting seaming information, we draw two-dimensional piece’s boundary and determine its border. The relationship between border frame and boundary points is built. Then the seaming information between corresponding boundary points can be set automatically when a pair of border frames is selected. Finally, we show the seaming information in 3D space immediately after setting a pair of seaming correspondence every time to avoid the problem of its cluttered display in 2D background. The experimental results show that the proposed method not only can high up the efficiency of seaming-information setting but also can make the seaming-information be displayed clearer and more intuitively, and then is suitable to set seaming information in different kinds of garments.
