摘　　要：研究了表面活性剂、络合剂对天然绿色彩棉颜色的影响。采用测色配色系统测定处理前后的绿棉颜色变化;使用显微镜观察溶胀纤维内部色素的分布情况;初步分析这些处理剂对绿棉日晒牢度的影响。试验结果表明,络合剂能有效提高绿棉织物日晒牢度,表面活性剂会改变绿棉色光,且对牢度影响较小。选择络合剂C、阴离子表面活性剂烷基苯磺酸盐、非离子表面活性剂T-3,以0.25∶15∶5复配后处理绿棉,日晒牢度可达到4级,效果较为理想。Effects of surfactants and chelating agents on colorstability in naturally green cotton were analyzed, changes in color before and after treatment were determined by color matching system, and pigments distribution in swollen fiber were observed by optical microscope. It was found that chelating agents could improve light fastness, and surfactants could exert influ- ence on the shade, while no influence on the fastness. Green cotton fabric featured light fastness above 4 level and little color deviation when treated with the combination of complex agent C, anionic suffactant D and nonionic surfactant T-3 of 0.25 ： 15 ： 5 .
