摘　　要：针对黑色天丝纤维染色深度不理想的问题,采用硫化黑染料分别对进口天丝A100和国产天丝希赛尔散纤维进行染色,同时以环保还原剂D替代传统硫化碱,探讨了染料质量分数、还原剂D质量浓度、烧碱质量浓度、染色温度、染色时间等因素对染色K/S值的影响。优化染色工艺为:染料10%、还原剂D10g/L、烧碱10g/L、85℃染色50min;天丝A100纤维染色后K/S值比希赛尔纤维高。染色后纤维湿摩擦色牢度为2级,色泣牢度及其他色牢度均达到4级以上。Aiming at poor dyeing depth of black Tencel fiber,imported Tencel A100 and domestic Tencel Thince⁃ll fiber are dyed with sulfur black dye respectively,and the traditional sodium sulfide is replaced by environ⁃ment-friendly reducing agent D.The effects of dye concentration,reducing agent D concentration,caustic soda concentration,dyeing temperature and dyeing time on K/S value of Tencel fibers are discussed.The optimized dyeing process is as follows:sulfur dye 10%,reducing agent D 10 g/L,caustic soda 10 g/L,dyeing at 85℃for 50 min.The K/S value of Tencel A100 fiber is higher than that of Thincell fiber.The color fastness to wet rub⁃bing is Grade 2,and the color fastness to bleeding and other color fastness are all above Grade 4.
