摘　　要：为解决棉深色织物湿处理色牢度较差的问题,使用聚四氢呋喃醚二醇(PTMG)、聚己二酸-1,4-丁二醇酯二醇(PBA)为复合软段,异佛尔酮二异氰酸酯(IPDI)、N-甲基二乙醇胺(N-MDEA)等制备阳离子水性聚氨酯(CWPU)固色剂,探讨了不同软段配比对CWPU乳液和胶膜性能的影响及其在棉织物上的固色效果。结果表明:随着PBA/PTMG质量比减小,胶膜拉伸强度减小,断裂伸长率增大。PBA/PTMG质量比为1∶1的CWPU固色剂整理性能较好,整理后织物耐干摩擦色牢度由3级提高至4~5级,耐湿摩擦色牢度由1~2级提高至2~3级,耐皂洗色牢度由3级提高至4级以上。In order to solve the problem of poor wet fastness of cotton dark fabrics, cationic waterborne polyurethane(CWPU) fixing agent is prepared by using isophorone diisocyanate(IPDI), n-methyldiethanolamine(N-MDEA) and complex soft segment, which including segment polytetrahydrofuranediol(PTMG), poly1, 4-butanediol adipate(PBA). The effect on properties of CWPU emulsion and film, as well as the color fixing effect on cotton fabric influenced by the matching of different soft segments are discussed. The results indicate that as the PBA/PTMG mass ratio decreases, the tensile strength of the adhesive film decreases and the elongation at break increases. The CWPU fixing agent with a PBA/PTMG mass ratio of 1∶1 has better finishing performance. After finishing, the color fastness to dry friction of the fabric increases from level 3 to level 4~5, the color fastness to wet friction increases from level 1~2 to level 2~3, and the color fastness to soaping increases from level 3 to above level 4.
