摘　　要：以异佛尔酮二异氰酸酯(IPDI)、聚己二酸-1,4-丁二醇酯二醇(PBA1000)、聚四氢呋喃醚二醇(PTMG1000)、N-甲基二乙醇胺(N-MDEA)、葡萄糖等为原料,硅烷偶联剂KH560为改性剂,制备KH560改性阳离子水性聚氨酯(K-CWPU)固色剂,并用于棉织物整理。优化的整理工艺为:K-CWPU固色剂60 g/L、轧余率80%,120℃焙烘60 s。整理后的织物耐干摩擦色牢度达到5级,耐湿摩擦色牢度达到3级,同时对色光影响不明显。The silane modified cationic waterborne polyurethane fixing agent(K-CWPU)is prepared with isopho⁃rone diisocyanate(IPDI),polyhexanedioic acid 1,4-butanediol ester glycol(PBA1000),polytetrahydrofuran ether glycol(PTMG1000),N-methyldiethanolamine(N-MDEA)and glucose as raw materials,and silane coupling agent KH560 is used as the modifier.The optimized finishing process is K-CWPU fixing agent 60 g/L,80%of pick-up,baking at 120℃for 60 s.The color fastness to dry rubbing and wet rubbing of the finished fabric can reach Grade 5 and Grade 3 respectively.The shade is not affected obviously.
