超仿棉混纺织物的染色工艺多为分散/活性染料两浴法染色,工艺复杂,能源消耗大,生产效率低.针对盛发纺织印染公司的需要,设计出经纱为涤纶、纬纱为仪纶和棉混纺纱的超仿棉基多元纤维——仪纶/涤纶/棉混纺织物,其中,仪纶、涤纶和棉的混纺比例为20∶50∶30,并对一浴法染色技术进行了研究.结果表明:仪纶/涤纶/棉混纺织物经过一浴法染色后,耐摩擦色牢度、耐皂洗色牢度、耐光色牢度为4级左右;回潮率为4.54％,远高于普通涤纶/棉(65/35)织物的2.20％;静电压为733 V,半衰期为1.14 s,与纯棉织物的静电压(701 V)、半衰期(1.04 s)相当,达到仿棉效果,并优于普通涤/棉混纺织物.“,”At present, the dyeing process of super cotton blended fabricis mainly two-bath dyeing with disperse/reactive dyes. The process is complex with highenergy consumption and low production efficiency. According to the requirements of Shengfa Textile Printing & Dyeing Co., Ltd., a super cotton-based yilon/polyester/cotton blended fabric was designed with warp yarn of polyester, weft yarn of yilon and cotton blended yarn. The blending ratio of yilon, polyester and cotton in this blended fabric was 20:50:30, and the one-bath dyeing technology was studied.The results showed that the rubbing fastness, washing fastness and light fastness of the blended fabric dyeing with the one-bath process reached 4 grade. The moisture regain of the blended fabric after one-bath dyeing was 4.54％, which was much higher than that of T/C blend (65/35) by 2.20％. Meanwhile, the static voltage and half life of the dyed fabric were 733 V and 1.14 s, respectively, which was similar to that of cotton fabric and better than T/C blend.
