经分纤处理蚕丝纤维的微孔填埋特性研究

Filling Character of Microvoids in Dispersing Bombyx Mori Silk

采用锡酸增重法来表征蚕丝纤维内部微孔 ,比较普通蚕丝纤维与分纤蚕丝纤维经锡酸填埋后的微观形态特征。结果表明 ,蚕丝纤维经分纤处理后填埋锡酸胶体的能力提高 ,且其填埋能力随分纤处理时间的延长而增加 ,证明蚕丝纤维经分纤处理后内部结构变得松散 ,有微孔生成。

Stannic acid weighting treatment is used to characterize the microvoids in pure silk.The morphology of ordinary degummed Bombyx mori silk and dispersing Bombyx mori silk after the weighting treatment is comparatively studied.Results show that the filling capacity of the Bombyx mori silk after the dispersion treatment increases and it increases with the dispersion treating time,which proves that the structure becomes looser and microvoids forms in the fibers' inner part after the dispersing treatment.
