摘　　要：将乙醇/水体系(90%乙醇体积分数)用于活性翠蓝H-A染色,讨论了乙醇体积分数对翠蓝H-A染色性能的影响,分析了三种染色体系中翠蓝H-A的染色动力学参数,并优化了乙醇/水体系染色工艺。试验结果表明,活性翠蓝H-A在乙醇/水体系中的上染率和固色率随体系中乙醇体积分数的提高而提高,翠蓝H-A的扩散系数较有电解质的常规水浴要小。两个染色体系的比染色速率常数相近。使用优化的翠蓝H-A乙醇/水体系工艺染色,织物的匀染性提高,各项性能达到常规水浴染色效果。The ethanol/water system （90% ethanol volume fraction） is used to cotton fabric dyeing with Reactive Turquoise Blue H-A. The effect of ethanol volume fraction on the dyeing performance of Turquoise Blue H-A is discussed. The dyeing dynamics of Turquoise Blue H-A in three dyeing systems are analyzed and the ethanol/water dyeing process is optimized. The results show that the dye uptake and fixation yield of Reactive Turquoise Blue H-A in ethanol/water system increase with the increase of etha- nol volume fraction, and the diffusion coefficient of Turquoise Blue H-A is smaller than that in conventional water bath having electrolyte. The specific dyeing rate constants of the two dyeing systems are similar. The levelness of fabrics dyed with optimized Turquoise Blue H-A process in ethanol/water system is improved, and the properties of fabrics reach those of conventional water bath.
