摘要
采用乳液聚合法,以苯乙烯、甲基丙烯酸甲酯、丙烯酸丁酯等为聚合单体合成聚丙烯酸酯乳液。对合成工艺进行优化,将最佳合成条件下合成的聚丙烯酸酯乳液与聚乙烯醇混合制备成整理液,对涤纶织物进行硬挺整理,探究聚丙烯酸酯质量浓度、聚乙烯醇质量浓度、焙烘温度和焙烘时间对织物硬挺整理的影响。结果表明:在阴离子/非离子乳化剂配比为1∶1,引发剂采用氧化还原体系时,所合成的聚丙烯酸酯乳液稳定性好,凝结物质量少。在聚丙烯酸酯乳液质量浓度为200 g/L,聚乙烯醇质量浓度为20 g/L,焙烘温度160℃,焙烘时间3 min的条件下对涤纶织物进行硬挺整理,织物的抗弯长度由1.96 cm提高至3.31 cm,断裂强力由851 N提升至1210 N,白度略微有所下降,静水压几乎无变化。
Polyacrylate emulsion is synthesized by emulsion polymerization using styrene,methyl methacrylate and butyl acrylate as the polymerization monomers.The synthetic process is optimized,and the polyacrylate emulsion is mixed with polyvinyl alcohol to prepare a finishing solution as a stiffing agent for polyester fabric.The effects of polyacrylate concentration,polyvinyl alcohol concentration,curing temperature and time on the stiffening finish are investigated.The results show that the polyacrylate emulsion synthesized with anionic/nonionic emulsifier ratio of 1∶1 and redox system as the initiator has good stability and less agglomerates.The stiffening finish of polyester fabric under polyacrylate emulsion of 200 g/L,polyvinyl alcohol of 20 g/L,and curing at 160℃for 3 min,the bending length of treated fabric is increased from 1.96 cm to 3.31 cm,the breaking strength is increased from 851 N to 1210 N,the whiteness is decreased slightly and the hydrostatic pressure is almost unchanged.
