纳米壳聚糖的制备及其对真丝纤维性能的影响

Preparation of chitosan nanoparticles and their effect on performance of silk fiber

采用离子凝胶法制备了平均粒径100nm以下的纳米壳聚糖,对比研究了纳米壳聚糖分散液和壳聚糖溶液对真丝纤维的填埋特征、微观形态和强伸力作用。结果表明,纳米壳聚糖分散液对真丝纤维处理后,填埋效果比普通壳聚糖溶液更为理想,真丝纤维经纳米壳聚糖处理后断裂强度和伸长率增大。

Chitosan nanoparticles of lOOnm below（Mean Diameter） are gained by the ionotropic gelation method in the study. Chitosan nanoparticles＇ filling characteristic on the silk is studied, as well as the morphology, breaking strength and enlogation of the silk yarn treated with chitosan nanoparticles. The results show that chitosan nanoparticles＇ filling effect on the silk is better than chitosan＇s and the breaking strength and enlogation of the silk treated with nanoparticles are improved.
