摘　　要：选取两种乙烯砜型活性染料对黏胶纤维进行染色,探讨了中性盐浓度和固色碱浓度对染料上染率、固色率和染色K/S值的影响,并对两种染料的染色特性参数S、E、F、R值进行了测试和分析。结果表明,中性盐对两种染料在黏胶纤维上的染色均具有明显的促进作用;两种染料染色时,最佳的碱浓度均为20 g/L;两种染料的母体结构差异明显,使其具有不同的染色特性参数,从而显示出对黏胶纤维不同的染色性能。Viscose fiber was respectively dyed by two kinds of divinyl sulphone active dyes respectively. The effects of the concentration of sodium chloride and sodium carbonate on the dye uptake, fixation rate and K/S value were discussed, and the S（substantivity）, E（exhaustion）, F（fixation） and R（reactivity） values of the two dyes were measured and analyzed. The results show that sodium chloride greatly accelerates the dyeing process of two dyes, and the optimum sodium carbonate concentration is 20 g/L. Because of the difference in dye matrix structure, the two dyes have different characteristic parameters of dyeing, thus resulting in the different dyeing property on viscose fiber.
