摘　　要：针对涤纶直接印花污染问题,围绕微量印花工艺要求,制备了4种液体分散染料和有机硅改性丙烯酸酯黏合剂SA,考察了4种液体分散染料的性能以及液体分散黄MR对合成增稠剂PTF-3流变性及黏度的影响,探索了黏合剂对市售分散蓝79和液体分散蓝MR染料固着率的影响,并测试了4种液体分散染料色牢度,对比了市售分散染料黄6G对印花浆流变性以及经还原清洗的市售分散蓝79残液吸光度的变化。结果表明:自制的液体分散染料具有较好的扩散性且不含禁用成分;黏合剂利于染料固着;采用含液体分散染料MR、黏合剂SA和增稠剂的印花色浆和热水洗后处理的微量印花工艺,具有良好的印花性能和优异的色牢度,可免除还原清洗,降低水资源消耗。Aiming at the problem of high pollution problem of direct printing on polyester fabric,according to the process requirements of micro-printing,4 liquid disperse dyes and acrylate binder SA modified by organic silicone were prepared.The properties of 4 liquid disperse dyes and the influence of liquid disperse blue MR on the rheology and viscosity of synthetic thickener PTF-3 were studied,and the influence of the binder on the dye uptake rate of commercial disperse blue 79 and liquid disperse blue MR were investigated.Moreover,the color fastness of 4 liquid disperse dyes were tested,and the influence of commercial disperse yellow 6G on the rheology of printing pulp and the change of the absorbency of the reduced and cleaned commercial disperse blue 79 residual liquid were compared.The results show that the self-prepared liquid disperse dyes have excellent diffusivity,and do not contain banned components.The binder is favourable to improve the percentage of dye uptake rate.The micro-printing process adopting printing color pulp containing liquid disperse dye MR,binder SA and thickener and the post-treatment by hot water washing has the advantages of good printing performance and color fastness,and can omit reduction and cleaning to reduce the water consumption.
