摘　　要：选取优可丝抗菌纤维与棉纤维进行混合纺纱,纺制了5.4tex的抗菌优可丝/棉混纺针织纱(捻度:370T/m),然后采用该种纱线在电脑横机上织造抗菌优可丝/棉混纺针织物,并采用天然植物靛蓝染料对其进行染色,探究最佳染色工艺。结果得到最优的染色方案为:NaOH浓度4g/L,保险粉浓度25g/L,还原时间5min,染色温度70℃;采用最优方案染色后,织物的水洗色牢度4~5级,干摩擦色牢度3~4级,湿摩擦色牢度3级。The antibacterial EcoCosy fibers and the coton fibers were mixed and spun to produce 5.4 tex antibacterial EcoCosy/cotton blended knitting yarn(twist:370 T/m).This kind of yarn was used to weave antibacterial EcoCosy/cotton blended knitted fabric on a computerized flat knitting machine,and it was dyed with natural plant indigo dyes.Its optimal dyeing process was explored.The results showed that the optimal dyeing scheme was:the concentration of sodium hydroxide was 4 g/L,the concentration of hydrosulfite was 25 g/L,the reduction time was 5 min,and the dyeing temperature was 70℃.After dyeing with the optimal scheme,the washing color fastness grade of fabric was 4-5,the color fastness grade to dry rubbing was 3-4,and the color fastness grade to wet rubbing was 3.
