Blended Yarns of Modacrylic Fibers with Silk Protein

The fiber properties of modacrylic fibers with silk protein and spinning technology for blended knitting yarns are studied. By testing the fiber properties, fiber spinn-ability is analysed. Modacrylic fibers with silk protein are brittle and have poor cohesion, so the key to process modacrylic fibers with silk protein lies in forming lap and sliver. During opening and carding, low speed is used to decrease fiber damage and the proper static resistant oil is applied to eliminate lapping fibers. Besides, the temperature and relative humidity have to be strictly controlled. The applications of modacrylic fibers with silk protein are also put forward.

Silk Fibroin Film Blended with Poly（ ethylene glycol-glycerin）

To improve the toughness of silk fibroin（ SF） films,poly（ ethylene glycol-glycerin）（ PEGG） was synthesized with ethylene glycol and epichlorohydrin. The SF / PEGG blend films were prepared by casting aqueous solution and their structures were characterized. The PEGG was in liquid state at room temperature so it will not be a single phrase at blend film. It crosslinked with SF and made it insolubility in water. The results of X-ray diffraction（ XRD） indicated that the crystallinity of the SF in the blend films decreased with the content of PEGG increasing. The tensile strength and elongation at break of blend films were measured using an instron tensile tester. The results showed that the tensile strength and elongation at break of blend films were high enough for application.After the blend films were stored at room temperature for 100 d,the crystallinity, the tensile strength and elongation at wet state increased. The blend films are superior to SF films in providing excellent flexibility and mechanical properties in both dry and wet states. Based on the fact that SF has good biocompatibility,the SF /PEGG blend film will offer new options in many different biomedical applications.     

国产精纺毛料风格特征考查

采集43种国产精纺毛料，用KES—FB风格仪测试出试样的16项基本力学指标，用日本20世纪70年代开发的男士西服面料和90年代开发的女士服装面料的风格评价方法评价面料的成形性和手感性能，发现目前的国产精纺面料仍然主要适合制服类服装，很难找到适合悬垂类和宽松挺括类服装的精纺毛料。同时，目前国产精纺毛料用做男士西服面料时手感好的不多；用作女士西服面料时与化纤面料相比手感的客观评价值仍然较高。     

Analysis of the Appearance Diameter of Yarns in Worsted Fabrics

Three-dimensional Rotational Microscopy was used to take the photos of the fabrics. Three categories of yarn appearance diameters in the worsted fabrics were discussed. The fabrics were grouped into two to explore the relationships between yam appearance diameters at the interlacing points, opening points, and the calculated yam diameters. The correlations between the appearance diameters and fabric parameters were given, and the results showed that the calculated yam diameter and warp cover factor had a very big influence on yam appearance diameter. The equations expressing the relationship between yam appearance diameters and fabric parameters are established using step-regression method. The validation of the equations for one type of fabrics shows a good accuracy with the average error below 9% except the weft fdaments exceeding 22%.     

基于神经网络的精梳毛纺纱线预测

在分析纺纱原理的基础上，采用人工神经网络建立7个不同的模型，预测精梳毛纺的纱线质量和纺纱性能，分别是纱线不匀、粗细节、断裂强力、强力不匀、断裂伸长和断头率。其中断头率由于其复杂的成因，采用了组合神经网络建模。采用工厂实际生产数据进行验证，前6个指标的预测值与实测值之间的相关系数的平方均超过0．9，断头的预测效果相比而言比较差，但相关系数的平方也超过了0．8，表明人工神经网络技术在精梳毛纺纱线预测方面有很大的应用前景。

Structure Changes of Silk Fibroin（SF） by Blending with Poly（ε-caprolactone）（PCL）：Characterization of SF and PCL Blended Electrospinning Films

The mechanical properties and water solubility of electrospinning SF films limit their use as biomaterials. In order to develop a tissue engineering biomaterial with both satisfying biological properties and sufficient biomechanical properties,blended films composed of silk fibroin（ SF） and poly（ ε-caprolactone）（ PCL） were fabricated by electrospinning in this study. Scanning electron microscope（ SEM）, X-ray diffraction（ XRD）,thermal analysis,Fourier transform-infrared（ FT-IR）,Raman spectra,mechanical testing,and water solubility were used to characterize the morphological, structural and mechanical properties of the blended electrospinning films. Results showed that the diameter of the blended fiber was distributed between 600 and1000 nm,and the fiber diameter increased as the PCL content increased. There is no obvious phase separation due to the similarity and intermiscibility,as well as the interactions（ mainly hydrogen bonds）, between the two polymers. Meanwhile, the secondary structures of SF changed from random coils and Silk I to Silk II because of the interactions between SF and PCL. For this reason,the tensile strength and elongation at break of the electrospinning films improved significantly,and the water solubility decreased. In conclusion,the blended electrospinning films fabricated in this study showed satisfying mechanical properties and water insolubilities,and they may be promising biomaterials for applications in tissue engineering for blood vessels,nerve conduits,tendons,ligaments and other tissues.
