摘要：

Bombyx mori (B. mor) silk was composed of natural fibroin, and could be attacked by light, heat, water, and microorganisms, etc. The changes of the structure and properties of B. mori silk fiber induced by moist-heat treatment were determined. It was observed that as the relative humidity increase from 0% to 70% at 150℃ decrease its tensile strength. Introducing water to the ageing environment promoted hydrolytic degradation. The concentration for serine and tyrosine decreased significantly as the relative humidity increasing, which resulted in increasing in yellowness index. The crystalline structure of silk fiber did not show any significant change except processing a slightly crystallinity arising. ©, 2015, Journal of Functional Materials. All right reserved.
