摘　　要：在腈纶纤维传统的染色工艺中,阳离子染料一直作为腈纶的专有染料,然而它的匀染性不高,以及成本高的问题一直难以解决。文章研究了以直接染料为原料,讨论了浴比、pH值、氯化钠质量浓度、染料用量以及固色剂对腈纶染色性能的影响。实验表明,腈纶经直接染料染色后再进行固色,其表观色深和耐水洗牢度有较大的提高。In the traditional acrylic fiber dyeing process,the cationic dye has always been the exclusive dye for acrylic.However,the issue that it is not high of level dyeing,as well as the high cost have been difficult to solve.This paper focused on that direct dyes as raw materials,and discussed the effect of the liquor ratio,pH value,sodium chloride concentration,dye concentration and fixing agent on dyeing properties of acrylics.The experiments show that the apparent depth and washable color fastness of acrylic were enhanced which was fixed after stained by direct dyes.
