摘　　要：介绍了一种阴离子型羊毛改性剂的合成,并对经改性剂处理后羊毛纤维的白度、碱溶解度、断裂强度及伸长率等性能进行了测定,讨论了改性羊毛对阳离子染料上染率的影响因素,测定了改性羊毛染色后的皂洗牢度和摩擦牢度。实验结果表明,羊毛经阴离子改性剂处理后机械性能基本不变,在100℃、pH值5、染色60 min后阳离子染料的上染率达到80%以上,并且具有较高的染色牢度。An anionic modifier for wool was synthesized. The properties of modified wool such as whiteness, alkaline solubility, breaking strength and extensibility were determined. The influenee factors on dye-uptake of cationic dye for modified wool were investigated. The friction fastness, soaping fasmess of modified wool after dyeing were also tested. The experiment result showed that the mechanical properties of wool were not changed after modification with the anionic agent, the dye-uptake of cationic dye was above 80% in the condition of 100 ℃, pH 5 and 60 minutes, and the dyeing fastness was high.
