柞蚕彩丝的结构和性能

为了解柞蚕彩丝与普通柞蚕丝在结构与性能上的差异,研发高附加值的柞蚕彩色制品,采用X射线衍射分析、声速模量法、热性能分析、力学性能测试等手段研究柞蚕彩丝的结构和性能,并与普通柞蚕丝进行了比较。根据丝素X射线衍射强度曲线定量计算及TG曲线和吸热峰的位置,可确定柞蚕彩丝结晶度和取向度均比普通柞蚕丝偏高,强力比普通柞蚕丝高6.5%,但伸长率减少3.5%,初始模量升高3.6%。普通柞蚕丝比柞蚕彩丝具有更优良的柔软性。

Structure and properties of colored tussah silk fibers

In order to comprehend the diffraction between structure and properties of colored tussah sille and ordinary tussah silk, high added value tussah silk fabics was researched and developed. The structure and properties of colored tussah silk fibers were investigated and compared with ordinary tussah silk by X-ray diffraction, sonic modulus method, thermal performance analysis and mechanical properties tests. According to the X-ray diffraction intensity curve, the TG curve and the  endothermic peak position are calculated, and the results show that the crystallinity and crientation degree of the colored tussah silk is a little higher than those of ordinary tussah silk. Thestrength of colored tussah silk is 6.5% higher than than ordinary tussah silk, but the elongation decreases by 3.5%, the initial modulus increases by 3.6%. The softness of ordinary tussah silk is superior to that of the colored tussah silk.
