摘要/Abstract

摘要： 本文以丙烯酸接枝改性尼龙66为主要研究对象，用阳离子红5BL在95℃下对其进行染色，研究改性尼龙66纤维与阳离子染料在弱酸性染浴中的染色性能，探讨了丙烯酸接枝改性率对改性尼龙66纤维与阳离子染料的染色动力学影响。实验结果表明：阳离子染料上染改性尼龙66纤维符合Langmuir 吸附方式，与普通尼龙66纤维阳离子染料染色相比，阳离子染料在改性尼龙66纤维上的染色速率增加，半染时间缩短，扩散系数增大，染色亲和力增加，水洗牢度提高半级至一级。

Abstract: The paper was mainly research acrylic grafting nylon 66. The cationic dye of Cationic Red 5BL was used to dye the fiber under 95℃. The dyeing properties of modified nylon 66 fiber in mild acidic condition were researched. The grafting modification rate and dyeing kinetics on the Acrylic grafting nylon 66 fibers with cationic dye were studied as well. The results showed that the type of adsorption isotherm of cationic dye on Acrylic grafting nylon 66 fibers was conforming to Langmuir distribution mechanism. Compared with dyeing with cationic dye on the conventional nylon 66 fiber, dyeing with cationic dye on the Acrylic grafting nylon 66 fiber has some features, i.e. the dyeing rate increases greatly, half-dyeing time decreases, diffusion coefficient and dyeing affinity enhance, washing fastness increased half to one degree.

Key words: graft modification, nylon 66, dyeing, dyeing kinetics
