摘要
利用SEM、FTIR、XRD、TG等测试方法研究了改性处理对桑蚕丝纤维结构和力学性能的影响,为其在桑蚕丝织物的改性研究中提供理论依据。研究结果表明:改性处理对桑蚕丝纤维表面具有明显的刻蚀作用,改性桑蚕丝纤维内部无规构象增加,相对结晶度略有提高,热分解起始温度略有下降。改性处理对桑蚕丝纤维结构的破坏主要在纤维的表层,对桑蚕丝纤维力学性能的影响很小。
The influence of the treatment on the structure and performance of silk fibers was examined by using SEM,FTIR,XRD,TG,and so on as to provide theoretical basis for modification research of silk fibers.The results showed that the surface of treated silk fibers was etched and the random conformation in the treated silk fibers increased.The relative crystallinity increased slightly and the onset decomposition temperature declined.However,the destruction on structure of the silk fibers was in their surface so that the treatment has little effect on the mechanical properties of the silk fibers.
