高分子量壳聚糖改性棉织物的染色性能研究

摘要

The dyeing behavior of cotton fabric modiifed with chitosan was studied in reactive dye bath. The results showed the modiifcation treatment could improve the dye uptake by 20.58%, K/S value by 24.85%and diffusion coefifcient by 7.3%, which meant the treatment was good for diffusing and dyeing. Moreover, the treatment had little impact on colour shade and fastness to rubbing.%本文探讨了高分子壳聚糖改性棉织物在活性染料中的染色性能。实验发现，经壳聚糖处理后，染色棉织物的上染百分率、K/S值及扩散系数分别提高20.58%、24.85%和7.3%，这说明高分子量壳聚糖改性有利于活性染料在棉织物内的扩散和上染，然而对染色织物的耐摩擦色牢度影响不大。
