Description

抗静电涤纶纤维改性剂
技术领域
本发明涉及纤维技术领域，具体涉及一种抗静电涤纶纤维改性剂及其制备方法。
背景技术
涤纶是合成纤维中的一个重要品种，是我国聚酯纤维的商品名称。它是以精对苯二甲酸(PTA)或对苯二甲酸二甲酯(DMT)和乙二醇(EG)为原料经酯化或酯交换和缩聚反应而制得的成纤高聚物——聚对苯二甲酸乙二醇酯 (PET)，经纺丝和后处理制成的纤维。
涤纶纤维制成的织物具有较高的强度与弹性恢复能力。坚牢耐用，免熨烫，易洗快干，但吸湿性差，穿着有闷热感，易产生静电而吸尘沾污，耐酸碱性、耐光的性能好，不怕霉菌、虫蛀。
发明内容

所述表面改性剂选自脂肪醇聚乙烯醚硫酸钠、十二烷基硫酸铵或脂肪醇聚乙烯醚硫酸铵的一种或几种。
所述抗静电剂为脂肪醇聚醚酰胺。
一种抗静电涤纶纤维改性剂制备方法，包括以下步骤：
(1)分别称取交联剂，乙二酸四乙酸二钠，乳化剂，石英粉，双氰胺，抗静电剂，去离子水，混合均匀后进行微波处理，得混合液；
(2)将步骤(1)所得混合液与正丁醇、无水乙醇混合加入反应釜中，进行酯交换制备相应的多元醇酯混合物；
(3)将表面改性剂和步骤(2)所得混合物加入调和釜中，混合后进行脉冲调和，并进行静态混合，然后同步搅拌1小时；
(4)调和搅拌完成后，取出，进行检验分析，得所述涤纶纤维改性剂。
所述步骤(1)中微波处理时微波功率为300-350W，微波频率为50kHz，间隔5min微波处理一次，每次处理10min，重复4-5次。
所述步骤(2)中进行酯交换时连续搅拌保持温度大于80℃，压力为1-2 个大气压。
本发明的有益效果为：本发明通过表面改性剂结合交联剂、正丁醇、乙二酸四乙酸二钠等组分对涤纶纤维表面进行改性处理，在纤维中有表面迁移的倾向，可补充纤维表面受损的抗静电层，是一种半永久性的抗静电方法；抗静电剂、乳化剂等与纤维以共混或共聚的形式存在，在纤维内部形成亲水的“导电通道”，是一种永久性的抗静电方法；本发明通过结合两种抗静电方法，使得涤纶纤维获得很好的抗静电性能，可适用于各种纤维制品，能够长时间保持抗静电性能；本发明所提供的改性剂制备方法，步骤简单，制得的改性剂均匀性好。
