The results show that ED GE reacts with silk fibroin and forms cross linkages through ether bond. The formation of cross linking was examined by FITR spectroscopy, soluble time in acid solution and changes of amino acids. Handle of treated silk with catalyst WSH is better than that of silk treated with the traditional catalysts such as thiosulfates and thiocyanates. Finishing technique, physical properties of the finished silk fabrics and evaluation of cross linkages are discussed.展开更多
