摘　　要：壳聚糖经改性得到阴离子型衍生物N,O-羧甲基壳聚糖（N，O—CMCTS），研究其与活性翠蓝KN—G、Remazol Red RGB、Remazol Golden Yellow RGB水解染料的作用状况，并用溶液的吸光度值及所形成胶团的粒径大小加以表征．研究表明：N，O—CMCTS质量浓度为0．5～1．0g／L时能够将织物表面解吸下来的水解染料包覆于所形成的胶团中，有效地去除织物表面的浮色．Chitosan was modified to obtain anionic derivative N,O-carboxymethyl chitosan （N,O-CMCTS）. The action between the anionic chitosan derivative and KN-G Blue,Remazol Red RGB and Remazol Golden Yellow RGB was studied, respectively, which was characterized by the absorbance of solution and the particle diameter of micelles. The result showed that N,O-CMCTS could effectively remove the loose color from the fabric surface when the mass concentration of N,O-CMCTS was 0.5-1.0 g/L, for it could wrap the hydrolyzed dyes desorbed from the fabric surface in the micelle.
