摘　　要：选用确定浓度、比例的十二烷基硫酸钠(SLS)与十六烷基三甲基溴化铵(CTAB)复配,在活性染浴中制备包裹染料的囊泡,通过透射电镜以及激光粒度仪对囊泡形成进行验证,并通过测定染色过程中上染曲线、不匀度、各项牢度来检测染色效果。结果表明:合适浓度、比例的阴阳离子活性剂复配,能够改善各种活性染料的匀染性能,不会降低染料的最终上染量,并且对不同种类的活性染料适用性较好。Compound surfactant vesicles wrapping reactive dyes were prepared by directly mixing sodium lauryl sulfate（SLS） and cetyl trimethyl ammonium bromide（CTAB） with certain total concentration、molar ratio in the dyeing bath. The formation of vesicles were confirmed by TEM and DLS instruments. The dyeing properties of the cationic modified cotton fabric were determined by testing the dyeing curve, leveling property and fastness. The results showed that the presence of SLS/CTAB vesicles can greatly improve the dyeing properties, especially levelling property without decreasing the total amount of dye which is covalently attached on the fibre. And the vesicles also exhibit good applicability to other dyes.
