Description

一种基于PTO的涤棉混纺织物的易去污整理新工艺
技术领域
本发明涉及纺织技术后整理领域，具体地说，是一种涤棉混纺织物的后整理工艺。
背景技术
涤棉混纺织物长久以来一直是纺织品生产的一个大类。由于其中的涤纶组分具有疏水性和亲油性，故涤棉混纺织物在服用过程中易于沾染油污，在干燥情况下易产生静电而吸附尘土，并且在洗涤时油污不易洗净还有再污染现象。因此，需要对涤棉混纺织物进行易去污整理。
易去污整理实际上是促进水向纤维内部和油污-纤维界面的扩散，由于促进了界面的水化，因而易使油污与纤维分离。水越易扩散，油污就越易脱落。而水的扩散取决于易去污剂的溶胀能力，而溶胀能力来源于其化学性能、亲水性、交联度及水洗温度等。当然，纤维内部进水后，使油污“卷珠”离去还需要一定的机械作用力。总的来说，只要使纤维亲水性增加，就能加快水的渗入，就能有利于去污。
目前，市场上应用效果较好的亲水易去污整理剂是改性氟碳树脂类助剂，氟碳树脂类整理剂分子中既含有拒油性的氟烷基链段，又含有亲水性的聚氧乙烯链段，如佛山市顺德区盈丰达化学工业公司生产的PTO易去污整理剂就是这样一种氟碳树脂溶液，外观呈乳白色或淡黄色乳液，兼具易去污和防止再沾污性能，但其易去污性能还有待进一步提高。
发明内容
本发明的目的在于克服上述不足，提供一种基于PTO的涤棉混纺织物的易去污整理新工艺，以实现涤棉混纺织物更好地易去污性能。
本发明一种基于PTO的涤棉混纺织物的易去污整理新工艺，所采用的工艺步骤包括：
（1）织物前处理：将织物于140～165℃条件下预定型，洗涤去除油污，用水冲洗至洗液pH为5～7，在90～120℃条件下将织物烘干，烘干结束后在150～180℃之间进行高温定型1～2min，得到半成品；
（2）将步骤（1）中烘干后的半成品放入整理液进行浸轧功能整理，轧余率为55～70％，所述整理液由以下浓度的组份组成：
佛州市顺德区盈丰达化学公司的易去污整理剂PTO 30～50g/L，增强剂LK-30 5～10g/L，聚醚衍生物HP 10～18g/L，防凝胶剂8～12g/L，所述整理液用0.5mol/L醋酸调节pH值为5～7；
（3）预烘、焙烘：将经过浸轧功能整理后的织物于110～130℃进行预烘，停留时间1～3min，再于150～180℃进行焙烘，停留时间4～6min；
（4）收卷：待焙烘后的织物自然冷却后收卷。
优选的，所述浸轧的方式为一浸一轧。
优选的，所述防凝胶剂为三乙基己基磷酸、十二烷基硫酸钠、聚丙烯酰胺、脂肪酸聚乙二醇酯中的一种或几种混合。
优选的，所述焙烘温度为170℃，停留时间5min。
本发明的有益效果：在浸轧的整理液中加入增强剂LK-30，提高了织物上易去污整理剂PTO的含量，在提高织物易去污性能的同时提高了织物的强度；加入聚醚衍生物HP，可与易去污整理剂PTO发生协同作用，能够提高织物的亲水性，同时大大提高了织物的易去污性能。
