新型碱剂E-5和纯碱的固色效果比较

新型碱剂E-5替代传统固色剂是活性染料染色的新技术之一，该文通过正交实验确定了活性染料新型碱剂E-5与纯碱固色的最佳工艺条件，并对两者的固色效果进行了分析比较。实验结果表明：新型碱剂E-5固色的固色率、色牢度、匀染性、重现性和稳定性优于纯碱固色，且其用量仅为纯碱的10% 左右，可节省碱剂用量和节省能源消耗，从而降低生产成本；新型碱剂E-5清洗容易，用其固色可节时省水，从而降低染色废水排放量，减轻环境污染。总之，新型碱剂E-5可完全替代纯碱作为活性染料染色的固色碱剂推广应用。

Comparison of Fixation Result by New-style Alkali E-5 and Sodium Carbonate

It is a new technique in reactive dyeing to replace traditional fixing agent with new-style alkail E-5.By means of orthogoanl experiment,this paper confirms the optimal conditions in which reactive dye is fixated with new-style alkail E-5 and sodium carbonate.It analyzes and compares their fixation results.The experimental results show that fixed color rate,color fastnesses,dyeing uniformity,repetition and stability of new-style alkail E-5 is better than sodium carbonate.Moreover,its dosage is about 10 of sodium carbonate,so dosage of alkail agent and production cost can be decreased.The washing of new-style alkail E-5 is easy,so emissions of dyed waste water can be lowered and environment pollution can be decreased.In a word,new-style alkail E-5 that substitutes sodium carbonate can be widely used in reactive dye dyeing.
