摘　　要：为降低分散染料直接印花废水废渣排放量,采用预乳化种子半连续乳液聚合法,以八甲基环四硅氧烷、丙烯酸丁酯、丙烯腈、苯乙烯、甲基丙烯酸、N-羟甲基丙烯酰胺为主要原料,制备了4种有机硅改性聚丙烯酸酯乳液。借助红外光谱、X射线光电子能谱表征了黏合剂的结构和性能;考察了黏合剂在液体分散蓝B-79微水印花中的作用;对比了微水印花和常规直接印花的后处理对废水排放及色牢度的影响。结果表明:黏合剂2和3应用于直接印花可提高染料固着率;微水印花织物仅需要80 ℃水洗,皂洗色牢度和干/湿摩擦色牢度都达4~5级;其废水化学需氧量值、残渣量和残留染料浓度仅是分散蓝H2GL直接印花的1/20、1/5和1/25,是一种绿色环保印花工艺。In order to reduce the disperse dye direct printing wastewater emission, the silicone-modified polyacrylate latex as polyester fiber binder was synthesized by the emulsion polymerization using butyl acrylate, styrene, acrylonitrile and octamethylcyclotetrasiloxane, methacrylic acid and N-methylol acrylamide as reactive monomers. The Fourier transform infrared spectrometer and X-ray photoelectron spectroscopy were adopted to characterize the chemical structure. The function of the silicone-modified polyacrylate binder in micro-water printing process of liquid disperse dye B-79 was investigated. The influence of post-treatment in conventional direct printing and micro-water printing on wastewater properties and color fastness was compared. The results show that the silicone-modified polyacrylates binder applied in directly printing can increase the dye uptake. After washing in hot water at 80 ℃, soaping fastness and dry/wet rubbing fastness are up to 4-5 level by the micro-water printing process. The value of chemical oxygen demand, the amount of residue and the dye concentration of wastewater are 1/20, 1/5and 1/25 of those by direct printing using disperse blue H2GL. Therefore, the proposed process is green and environment-friendly.
