COMSOL Multiphysics finite element simulation software was employed in this study to mimic the way the process parameters influence the magnitude and distribution of the electric field intensity during multineedle electrospinning process. Systematic analysis was conducted on how the factors such as the number, diameter, length, spacing of the spinning needles and applied voltage influence the magnitude and distribution of the field intensity of each needle. The results indicated that the peak value of field intensity occurs at needle tip for single needle electrospinning, while the peak values will occur at the tip outsides of the needles located at the bilateral sides of the linear needle array, and the field intensity of the middle needles decrease due to the suppression actions from the side needles, which are the key reasons for the occurrence of “End effect”. In addition, the peak intensity of the outside needles was found to decrease significantly with the increasing in the number, diameter and length of the needles, while the increase in the applied voltage and the decrease in receiving distance would enhance the peak intensity of electric field notably. These findings will play important role and provide theoretical support for improving the electric field and its distribution in multineedle electrospinning.

Abstract: Cotton fabrics were selectively oxidized by HNO3/H3PO4-NaNO2 mediate system to obtain the monocarboxyl cellulose, and then chitosan bonded with monocarboxyl cotton fabric through the amide reaction in chitosan solution. Effects of oxidation time of HNO3/H3PO4-NaNO2 on carboxyl content, breaking strength of oxidized cotton fabrics and weight gain of cotton fabric grafted chitosan were studied and the maximum weight gain of 5.52% was obtained when the oxidation time was chosen as 45min. The analysis of CP/MAS 13C NMR, FT-IR, SEM and XRD demonstrated that the primary hydroxyl at C6 site in glucose units of cotton cellulose was selectively oxidized to carboxyl group by HNO3/H3PO4-NaNO2 system, subsequently the amido bond of C-N was formed between amino groups in chitosan and active carboxyl groups on oxidized cotton fabrics and chitosan covered on the surface of oxidized cotton fabrics by the covalent bond. After chitosan graft reaction, the crystallinity of monocarboxyl cotton fabric decreased from 65.37% to 60.86%, and the breaking strength, whiteness and capillary effect of chitosan grafted cotton fabrics slightly reduced, whereas the wrinkle recovery angle of modified fabrics significantly increased.

Soybean dregs/starch composite films were prepared by soybean dregs and starch as raw material with glycerin and sodium hydroxide as solvent in fusion method. The mechanical properties and the solution viscosity of the composite films were also investigated. The effects of the concentration of NaOH, ratio of soybean dregs /starch and the content of glycerol on the melt viscosity and breaking strength of the composite film were studied by adopting twice common rotation combined design and experiment scheme. Results showed that the addition of NaOH and the ratio of soybean dregs/starch are important factors affecting the film-forming of composite films. When the concentration of NaOH was 17%, the ratio of soybean dregs/starch was 1.135 and the content of glycerol was 0, the solution viscosity of the composite film could be best as 6.25kpa?s and its breaking strength of the film was better than common film as 4.21Mpa.

Using the probability density function with parameters to characterize the cotton fiber length distribution, it is not only conducive to the calculation of some fiber length indicators, but also beneficial to fully discribe the fiber length distribution. Based on the fiber length frequency histograms measured by USTER AFIS Pro., two- and three-component mixed Weibull distributions are adopted to fit these histograms, and the relevant length indicators are calculated. The results show that the mixed Weibull distribution can well fit length distribution of cotton fibers. In addition, by comparing the calculated values with the tested ones, two-component mixed Weibull distribution is superior to three-component mixed distribution.

Focusing on identification of different types of defects on different fabrics, a defects detection method based on matrix singular value decomposition (SVD) was presented. Firstly, a region of interest (ROI) containing the defect is identified by a proposed adaptive partitioning technique. The ROI portion of fabric image is then divided into several small non-overlapping sub-images for the singular value decomposition. Since singular values are related to energy information of the image, the remaining singular values are used to restructure the sub-image by getting rid of the singular values represented the fabric texture background energy information, thus improving the energy difference between defect region and texture background. When these sub-images are used to restore the ROI area, there will be a situation that the gap is not fully connected. Binarization threshold processing is then used to eliminate the impact, thus accomplishing the fabric defect detection. Experiments have shown that the improved singular value decomposition technique presented is short time-consuming and high efficiency. Most defects can be able to identify their location and shape in the selection of the seven different fabric textures.

All of the historical silk textiles were dyed with natural materials, most of which were vegetable dyestuffs. In present studies, seven vegetable dyes were identified by non-destructive method-miniature spectrometer with fiber optics. This method was successfully applied to acquiring the ultraviolet-visible absorption spectra of madder, Amur cork, pagoda tree, sappanwood etc. In addition, miniature spectrometer with fiber optics was also used for light-fastness evaluation of vegetable dyes. Seven samples have been exposed in Xenon lamp at4.32×104w/m2, and the results indicated that the light-fastness of Amur cork was lowest, whereas the light-fastness of indigo was much better. Thus, miniature spectrometer would serve as a non-destructive technique for quick analysis of natural dyestuffs; also, this method can help to slow down the effect of light-ageing for the historical silk textiles during a period of exhibition and conservation through establishing suitable light environment.
