摘要
为提升涤棉织物涂料喷墨印花工艺的印花性能,采用半连续种子乳液聚合法,以醋酸乙烯酯(VA)、丙烯酸丁酯(BA)和丙烯酸异辛酯(EHA)为共聚单体,丙烯酸羟乙酯(HEA)为功能单体,引入硅烷偶联剂(KH-1706),制备得到有机硅改性聚丙烯酸酯乳液(KH-1706/PVAc),并将其作为预处理液应用于涤棉织物;探究引入不同质量分数的KH-1706对乳液烘干后所得乳胶膜性能的影响,并分析以KH-1706/PVAc为预处理液对涤棉织物涂料喷墨印花性能的影响.结果表明:当引入KH-1706的质量分数为2％时,乳胶膜具有较好的热稳定性和耐水性,吸水率为16.8％;乳液运用于涤棉织物预处理后,有效抑制了墨滴在织物上的渗化,墨滴渗化面积为20.8 mm2;预处理后印花织物耐湿摩擦牢度提高半级,印花精细度提升约13％,并且复杂图案打印后仍具有较好的印花效果,表现出良好的综合印花性能.该研究可为提升涤棉织物涂料喷墨印花的印花性能提供理论参考.
Abstract
To enhance the printing performance of pigment inkjet printing technology of polyester-cotton fabrics,a silicone-modified polyacrylate emulsion(KH-1706/PVAc)was prepared via semi-continuous seed emulsion polymerization and applied as a pretreatment solution on polyester-cotton fabrics.Copolymerized monomers including vinyl acetate(VA),butyl acrylate(BA),and 2-ethylhexyl acrylate(EHA)were utilized.HEA served as a functional monomer,while a silane coupling agent(KH-1706)was introduced.The aim of this study was to investigate the effect of different mass fractions of KH-1706 on the properties of the latex film produced after emulsion drying,and the effect of using KH-1706/PVAc as a pre-treatment solution on the performance of polyester-cotton fabrics in pigment digital printing.The results indicate that the introduction of a 2％mass fraction of KH-1706 improved the thermal stability and water resistance of the latex film,resulting in a water absorption rate of 16.8％.Moreover,the application of the emulsion as a pre-treatment on polyester-cotton fabrics effectively prevented droplet penetration on the fabrics,with the area of droplet infiltration being 20.8 mm2.The study found that pre-treated printed fabrics improved their fastness to wet rubbing by half a grade and increased printing fineness by about 13％.Additionally,the complex pattern maintained a good printing effect after printing,demonstrating good comprehensive printing performance.This study provides valuable insights for enhancing the printing performance of pigment ink-jet printing on polyester-cotton fabrics.
