摘　　要：采用十甲基环五硅氧烷(D5)代替水作为蚕丝纤维弱酸性染料染色介质,讨论了染色温度和保温时间、带液率、浴比对染色织物匀染性和表观深度的影响,并测试了染色织物K/S值、上染率及各项染色牢度。优化的体系染色工艺为:弱酸性红RS相对于织物质量分数2%,浴比1︰40,带液率160%,染色温度90℃,保温时间30 min。试验结果表明,织物只需以一定带液率入染D5染色体系,便可获得常规水浴染色基本相同的染色效果,且无需添加任何分散剂,达到生态环保的目标。This study uses decamethylcyclopentasiloxane （D5） instead of water as the dyeing medium of weak acid dye of silk fiber, discusses the influence of dyeing temperature, heat preservation time, liquid rate and bath ratio on levelling property and apparent depth of dyed fabrics and tests K/S value, dye uptake and various color fastnesses of dyed fabric. The optimal dyeing process is： mass fraction of weak acid red RS Vs fabric is 2% , bath ratio 1：40, liquid rate 160% , dyeing temperature 90 ℃ and heat preservation time 30 rain. The test result shows that fabrics can get the dyeing effect basically same as conventional water bath dyeing only through D5 dyeing system with certain liquid rate. It is unnecessary to add any dispersing agent and the objective of ecological environmental protection can be achieved.
