摘　　要：叔胺化合物作为染料中的固色催化剂,能够起到使活性染料对纤维素纤维可在较为低的碱盐用量的条件下染色的作用,从而减少印染工业中染液废水对环境造成的污染,减少对生态环境的破坏。以不同的催化剂用量、活性染料染色时的条件改变及改性工艺方面的应用,可对纤维素纤维的染色时上色率及得色深度的产生影响。实践证明:叔胺类催化剂能对活性染料染色产生明显的催化作用,叔胺类催化剂对棉织物的染色改性及其他染色条件的改进有重要的意义。As a fixation catalyst in dyes, tertiary amine compounds can enable reactive dyes to dye cellulose fibers withrelatively low alkali salt content, thus reducing the environmental pollution caused by dye waste water in the printing and dyeingindustry and reducing the damage to the ecological environment. Using different amount of catalyst, changing the conditions ofreactive dye dyeing and the application of modification technology can influence the coloring rate and the depth of color ofcellulose fiber. It was proved that tertiary amine catalysts can catalyze the dyeing of reactive dyes, and it was of greatsignificance to improve the dyeing modification and other dyeing conditions of cotton fabrics with tertiary amine catalysts.
