Description

一种环保抗氧化涤纶DTY油剂及其制备方法
技术领域
本发明涉及纺丝油剂领域，具体涉及一种环保抗氧化涤纶DTY油剂及其制备方法。
背景技术
我国化纤工业近几年发展迅速，其中涤纶产品占到总产量的80%以上，随着涤纶工业的发展，对涤纶油剂的需求，无论是品种或者数量都越来越多，对涤纶油剂的质量要求也越来越高。DTY油剂是涤纶DTY纤维加工过程中必不可少的，需要能调节纤维的摩擦特性，赋予纤维平滑、柔软等特性，使化学纤维顺利通过纺丝、拉伸、加弹纺纱、织造等工序，确保化纤生产的顺利进行。
目前，涤纶DTY油剂通常由平滑剂、乳化剂、抗静电剂等成分组成。其中烷基酚聚氧乙烯醚(APEO)是广泛使用的乳化剂，其对环境潜在的危害已经被广泛的研究和论证，2003年欧盟专门制订了限制APEO使用的法规性文件“2003/53/EC指令”，其中明确界定：出口欧洲纺织品和服装上的APEO的限量不超过0.1%。
现有的普通DTY油剂抗氧化性差，容易使涤纶DTY纤维变黄，从而造成重大损失；耐热性差，温度过高时会严重挥发，产生较大烟雾；传统DTY油剂含有APEO成分，会造成环境污染，以及影响下游企业的产品出口。
发明内容
为了解决上述问题，本发明的目的是提供一种性能稳定，可纺性好，生物降解性好，能满足涤纶纤维高速纺丝工艺要求，有效提高涤纶纺丝质量。为达到上述的目的，本发明采用如下技术方案。
