摘要 采用毛用和棉用活性染料对锦纶纤维染色,详细讨论了染色温度、染浴pH值、染色和皂洗方法对染色深度和固色率的影响,分析了不同类型的活性染料对染色条件的敏感性。活性染料对锦纶纤维的染色深度、固着率和固着效率受温度、pH值、染料母体结构和活性基的影响很大。毛用活性染料更适合于锦纶纤维的染色,普通乙烯砜硫酸酯及乙烯砜硫酸酯/一氯均三嗪染料可有选择性地加以使用,毛用活性染料合适的染色pH值约为4,其它染料适用的pH值因品种而异.采用酸性染色或先酸性后碱性的染色条件均可,后者的优点是固着效率高,但染色深度未见提高,染色后采用碱性条件皂洗有利于染色深度的提高. The reactive dyes for wool and cotton are used to dye polyamide fibers. The influence of dyeing temperature, pH values, and dyeing and soaping methods on color depth and fixation ratio is discussed. The color depth and the fixation are greatly affected by dyeing temperature, pH, chromophores and reactive groups. The reactive dyes for wool are appropriate for dyeing polyamide fibers, and the optimum pH was 4. The optimum pH values of other dyes depend on their diverse nature. It's OK to use the acid dyeing or first the acidity and then the alkalinity dyeing condition, dyeing-fastness of the latter is high, but the.dyeing depth is not enhanced. Then the dyeing depth is enhanced when they are washed on eonditon of the alkalinity soaping.
