摘　　要：柔丝是一种将植物蛋白质嫁接到再生纤维素纤维(黏胶)上的改性黏胶蛋白纤维。选用27.7tex的柔丝/甲壳素/长绒棉(30/40/30)混纺纱编织纬平针织物,研究了织物的染色工艺与性能。根据该3组分原料特点,在尽量减少织物强度损失的前提下,选择合适的前处理工艺,以增加织物润湿性,并获得稳定的白度。设计染色试验方案,通过正交试验,优选获得的染色工艺参数为元明粉50g/L,纯碱10g/L,浴比1∶10。Rose is a kind of modified protein viscose fiber by grafting plant protein onto regenerated cellulose fibers. With one type of 27.7 tex rose/chitin/long-staple cotton （30/40/30） chosen to knit the plain weft knitted fabric, the dyeing process and properties of the fabric were discussed. According to both the characteristics of three component fibers and under the condition of minimizing the loss of strength, the suitable pretreatment conditions were chosen to increase the wettability of fabric and obtain stable whiteness. By orthogonal experimental, the results showed that the optimization of dyeing process parameters were anhydrous sodium sulfate （50 g/L）, sodium carbonate （20 g/L） and bath ratio （1 ： 10）.
