Abstract:

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 of structure of the silk fibers was in their surface so that the treatment has little effect on the mechanical properties of the silk fibers.
