Study on the Structure and Properties of Natural Color Silk Treated by Alkali

Abstract:

Article Preview

The natural color silk has been treated by sodium hydroxide and sodium carbonate,and the structure, crystallize and mechanical properties of the treated natural color silk were studied. The results showed that the structure of natural color silk was not changed and the degree of crystallinity decreased; the crystallinity of un-treated natural color silk was 44.4%, while the crystallinities of natural color silk treated by sodium hydroxide and sodium carbonate were 35.2% and 43.6%, respectively. The breaking tenacity and the breaking elongation of natural color silk treated by sodium hydroxide dropped dramatically and the Young’s Modulus declined; but these properties of natural color silk were not changed significantly after being treated by sodium carbonate.
