摘要： 高力份和稳定的液体分散染料制备存在技术上的困难，为制备高力份和稳定的分散橙288液体染料，文章研究了助剂对液体染料稳定性的影响，比较了轧烘汽蒸工艺和浸染染色工艺对涤氨纶针织物染色性能的影响。结果表明：采用L229超支链聚合物能明显提高分散橙288液体染料的稳定性，优于其余超支链聚合物（LD20、LD12、TS420）、乙二醇和甘油，分析了液体染料双电层的稳定机理。制备的分散橙288液体染料采用轧烘汽蒸工艺和浸染染色工艺都能获得优良的染色性，仅需要采用热水洗的染色后处理工序，摩擦色牢度达4～5级及以上，是一种能免除传统还原清洗的短流程染色工艺，采用轧烘汽蒸工艺，涤氨纶针织物的顶破强度损伤较小。

Abstract：

There are technical difficulties in the preparation of high-strength and stable liquid disperse dyes. In order to prepare high-strength and stable disperse orange 288 liquid dyes， the effect of auxiliaries on the stability of liquid dye was studied， and the effects of rolling， drying and steaming process and dip dyeing process on the dyeing performance of polyester spandex knitted fabric were compared. The results showed that the use of L229 hyperbranched polymer could significantly improve the stability of disperse orange 288 liquid dye， which was better than other hyperbranched polymers（LD20， LD12， TS420）， ethylene glycol and glycerin. The stability mechanism of double electric layer of liquid dye was analyzed. The prepared disperse orange 288 liquid dye could obtain excellent dyeing property by rolling， drying and steaming process and dip dyeing process. Only the post-treatment process of hot water washing was needed， and the friction color fastness reached Grade 4-5 and above. It is a short process dyeing process that could avoid reduction cleaning. The bursting strength of polyester and spandex knitted fabric was less damaged by rolling， drying and steaming process.

與粉末状分散染料相比，液体分散染料在染料制造过程中可免除喷雾干燥，在染料应用过程中无粉尘污染和计量准确，以及废水排放量低和废水色度低等优势，是近几年研究的热点课题[1]。这是因为在分散染料制备过程中，采用更少的高效表面活性剂替代了传统阴离子分散剂（分散剂MF、CNF等），而过量的分散剂抑制了分散染料对聚酯纤维的上染和固着，增加了纤维表面的浮色，因此需要通过还原清洗工序来提高染色制品色牢度，加重了废水排放量和废水色度[2-3]。与粉末状分散染料的高力份和优良储存稳定性相比，液体分散染料存在力份低和易产生沉降的不足[4-6]。……
