摘　　要：在聚丙烯酸酯乳液中加入具有增白效果的高岭土填料制成涂层用浆料,然后对涤纶针刺基布进行涂层整理,通过研究涂层浆体系各组分用量及涂层工艺对涂层材料耐折力、附着力、断裂强力及表面性能等的影响,确定最佳涂层浆配方及涂层工艺,从而制备适用于数码喷墨印花的涤纶非织造布涂层材料。结果表明:当分散剂CF-10用量为0.3 wt%,交联剂SAC-100用量为0.3 wt%,聚丙烯酸酯涂层剂用量为20.0 wt%,涂层剂与高岭土质量比为1∶4时,可以制备得到性能优良的涂层浆;将所制涂层浆用于非织造布涂层,当后处理焙烘温度为160℃,焙烘时间为90 s时,可以制备得到耐折力和附着力好、手感较佳的涂层材料;对制备的涂层材料进行UV数码喷印,所得图案的干摩擦色牢度为4~5级、湿摩擦色牢度为3~4级,图案颜色鲜艳且边缘清晰。该涤纶针刺非织造布涂层材料对于拓展非织造布应用领域具有重要意义。The coating slurry was prepared by adding the kaolin filler with whitening effect into the polyacrylate emulsion,and then the polyester needle-punched fabric was coated.And the effects of the dose of each component of the coating slurry system and the coating process on the bending resistance,adhesion,breaking strength and surface properties of the coating material were studied to determine the optimal formula of coating slurry,and the polyester nonwoven coating materials for digital inkjet printing were prepared.The results show that the coating slurry with excellent properties could be prepared under the following conditions:The dose of dispersant CF-100.3 wt%,dose of cross-linking agent SAC-1000.3 wt%,dose of polyacrylate coating agent 20.0 wt%,and the ratio of coating agent to kaolin 1∶4.Then the coating slurry was used for non-woven coating.When the baking temperature was 160℃and the baking time was 90 s,the coating materials with good bending resistance,adhesion and soft hand feeling could be prepared.Then UV digital printing was performed for the coating materials,and the pattern gained had grade 4~5 dry rubbing color fastness,and grade 3~4 wet rubbing color fastness.Besides,the obtained pattern also had bright colors and sharp edges.The prepared polyester non-woven coating material has great significance for expanding the application field of non-woven.
