摘　　要：为解决目前染整行业常用抗皱整理剂2D树脂的甲醛释放,以及近年来开发的多羧酸类、缩醛类、环氧树脂类等抗皱整理剂整理效果不佳、整理后织物强力降低等问题,通过溶液共聚法将自制的聚氨酯单体与丙烯酸酯类单体和乙烯基三甲氧基硅烷共聚制备了有机硅改性聚氨酯/丙烯酸酯共聚乳液,并考察了其对棉织物的抗皱整理效果。结果表明:当共聚乳液质量分数为5%,浸渍总时间为7 min,80℃预烘3 min,135℃烘焙5 min时,所整理棉织物的经纬向折皱回复角分别增大60.6°和39.1°,断裂强力增大43.3 N,断裂伸长率增大10.1%,同时还可赋予织物良好的拒水性能。In order to solve the problem of formaldehyde release from 2D resin used commonly as anti- wrinkle finishing agent in dyeing and finishing industry, as well as poor finishing effect and fabric strength reduction after finished by such anti-wrinkle finishing agents as polycarboxylic acids, acetals and epoxy resin developed in recent years, polyurethane/acrylate copolymer emulsion was prepared using the homemade polyurethane monomer and acrylate monomer as raw materials and wrinkle vinyl trimethoxysilane as modifier by solution copolymerizafion. The anti-wrinkle finishing effect of cotton fabric was investigated. The results show that anti-wrinkle finishing properties of the copolymer emulsion for cotton fabric achieve the optimal effect under the conditions of the mass concentration of polyurethane/ acrylate copolymer emulsion reaching 5% , impregnating for 7 min, pre-baking at 80℃ for 3 min and baking at 135℃ for 5 min, and the wrinkle recovery angles of warp/weft of the finished fabric increase by 60. 6° and 39. 1°, respectively, while the breaking strength increases by 43.3 N and the elongation at breaking increases by 10. 1%. At the same time, the finished fabric has good waterproof performance.
