摘　　要：采用酸性染料染细纤度蚕丝,研究pH值、元明粉用量、染色温度等因素对染色效果的影响;通过与普通蚕丝的染色性能对比,探讨细纤度蚕丝染色性能的优缺点。结果表明,优化的染色工艺为:元明粉10 g/L,pH 5,45℃入染,升温至90℃,保温30 min;细纤度蚕丝相比于普通蚕丝,其上染率高,上染速度快,但表观色深浅,通过优化工艺可以弥补色光较浅的缺陷。Fine denier silk fibers are dyed with acid dyes. The effects of pH value, sodium sulfate dosage and dyeing tempera- ture on the dyeing results are discussed. The results show that the optimum dyeing conditions are： sodium sulfate 10 g/L, pH value .5, initial dyeing temperature at 45 ℃,and heated to 90 ℃ for 30 min. Fine denier silk fiber has higher dye-uptake, rapid dyeing rate but light in apparent color depth which can be made up by optimizing the dyeing conditions comparing with the ordi- nary silk fibers.
