Abstract:
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 reduced 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 winvl trimethxysilane as modifier by solution copolymerization. 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 achieved 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 increased by 60.6° and 39.1°, respectively, while the breaking strength increased by 43.3N and the elongation at breaking increased by 10.1%. At the same time, the finished fabric has good waterproof performance.
Key words: polyurethane/acrylate emulsion, silicone modification, anti-wrinkle finishing, waterproof performance, cotton fabric
