摘　　要：采用壳聚糖溶液对盐缩丝纤维进行处理,对比分析了普通桑蚕丝和不同盐缩时间处理盐缩丝的增/失重情况,并对壳聚糖处理后的丝纤维的微观形态、聚集态结构和力学性能进行了研究。结果表明,经壳聚糖处理后,盐缩丝纤维表面有壳聚糖附着,丝纤维结晶度提高,内部结构呈β化趋势。壳聚糖处理后盐缩丝的断裂强度基本不变,急弹性和弹性变形增加。Calcium nitrate modified silk treated with chitosan solution was investigated in the paper. Weighting properties of calcium nitrate modified silk with different chitosan treatment time were studied, as well as their morphology, aggregation structure and mechanical properies. The results show that the chitosan attach to the treated silk surface, the crystallinity of silk fiber increases and the trend of β -sheet is apparent, the breaking strength is stable, while the flexibility and spring distortion are increased after chitosan treatment.
