涤纶针织物吸汗速干整理实践及常见问题分析

Practice of Sweat Absorption and Flash Drying Finishing of Polyester Knitted Fabric and Analysis of Common Problems

阐述了吸汗速干整理的原理,并选用吸汗速干整理剂PR-868EZ,通过染色同浴、染后浸渍及染后浸轧3种方法对涤纶针织面料进行整理加工。测试并比较了不同方法整理后涤纶针织面料的吸水性、导湿性、速干性,以及对色光、色牢度的影响。详细分析了生产中常见的吸汗速干整理问题。结果表明,3种方法整理后,面料的吸水性、导湿性及速干性均能得到显著地改善,但染后浸渍及染后浸轧处理的面料,超过10次水洗,其速干性无法满足要求;3种处理方法对面料的色光影响都较小;染色同浴整理可满足常规服装色牢度要求,染后浸渍及染后浸轧整理对面料色牢度的影响较大。

The principle of sweat absorption and flash drying finishing was expounded, and polyester knitted fabrics were finished by three methods of dyeing in one bath, dipping after dyeing and padding after dyeing with sweat absorption and flash drying finishing agent PR-868EZ. The water absorption, wet permeability and flash dry- ing property and the effects on color shade and color fastness of polyester knitted fabric after different methods were tested and analyzed. The problems of sweat absorption and flash drying finishing in production were analyzed in de- tail. The results show that the water absorption, wet permeability and flash drying property of fabric after finishing by the three methods are improved obviously, but the flash drying property of fabric finished by dipping after dye- ing and padding after dyeing can not satisfy requirement when after 10 times washing; the three methods have little effects on color shade; dyeing in one bath can satisfy the color fastness requirement of common garment, dipping after dyeing and padding after dyeing have great influence on color fastness.
