经等离子体处理的蚕丝纤维结构与性能

Structure and Properties of Mulberry Silk Fiber after Plasma Treatment

采用低温氧等离子体对蚕丝纤维进行处理 ,研究了等离子体处理后蚕丝纤维聚集态结构的变化情况。结果表明 :低温氧等离子体处理使蚕丝纤维内部构象由无规向β折叠转化 ,纤维的结晶度下降 ,同时 ,蚕丝纤维因弱结构剥离产生重量损失 ,短时间处理对蚕丝纤维强度影响不大。

Mulberry silk was treated with low-temperature-oxygen plasma,the changes of its conglomeration state were studied. Show that:The inner conformation changed fr om ra ndom coil to β-sheet. The degree of crystallization of silk decrease and littl e more weight loss at same time,due to the erosion of weak structure after plasm a treatment. No more influence to tensile strength after a short-time plasma tr eatment.
