摘 要:活性染料染色常用Na_(3)PO_(4)、Na_(2)CO_(3)、NaOH作为固色剂,但Na_(3)PO_(4)含磷量高不符合环保要求,早被淘汰;Na_(2)CO_(3)使用量大,染色工人劳动强度大,成本高;NaOH作为强碱染色不稳定难以操作。以混合碱Na_(2)CO_(3)和新型碱剂WF-AKLN取代其他碱剂,探讨两者对染料上染率、匀染性、色差和色牢度的影响。合理使用混合碱Na_(2)CO_(3)和代用碱WF-AKLN,选择染色效果较好的适宜染料,染料的上染率和色牢度与用其他碱剂固色基本一致,色差更小,匀染性良好。Na_(3)PO_(4),Na_(2)CO_(3) and Na OH are often used as alkali fixing agents for reactive dyeing.Na_(3)PO_(4) has been phased out because of its high phosphorus content and environmental damage.The large use of Na_(2)CO_(3) often leads to great labor intensity for dyeing workers and high costs.Besides,Na OH is unstable and difficult to operate as a staining alkali.The mixed alkali Na_(2)CO_(3) and the new alkali agent WF-AKLN are used to replace other alkali agents,and the effects of these two alkali agents on the dyeing rate,uniformity,color difference and color fastness of dyes are discussed.When a reasonable amount of mixed alkali Na_(2)CO_(3) and substitute alkali WF-AKLN are used and a suitable dye with better dyeing effect is selected,the dyeing rate and color fastness will be the same as other alkali fixing agents,with a smaller color difference and good levelness.
