无氟拒水剂对涤纶织物的拒水整理研究
|
摘要
由于含氟整理剂对人体有害,开发新型无氟整理技术已成为当今拒水整理的研究热点。文章分别研究了硅类、超支化大分子类、蜡质类拒水剂对涤纶织物的整理工艺,筛选了比较合理的拒水剂用量和工艺参数,并对拒水整理后涤纶织物的耐水洗性进行了测试。研究结果表明:拒水剂浓度60～70 g/L、170℃下处理70 s时,涤纶织物拒水等级可达到90,经5次水洗后织物仍有较优异的拒水效果;超支化大分子及蜡质拒水剂整理后不影响后序PU涂层,可达到与氟类拒水剂相同的效果。
Non-fluorinated water-repellent finishing is a very hot topic as the fluorinated water-repellenct agent has bad effect to people' health. In this paper, the finishing process of silicon, the hyperbranched macromolecules and the wax water repellent agents were studied respectively. The water-repellent effect of the finished polyester fabric after washing and the influence to the PU coating of the fluorine-free agent was investigated, too. The results showed that the degree of the polyester fabric was 90 when the fabricwas treated in concentration of 60 ～ 70 g/L at temperature of 170 ℃ for 70 s, and there was 80 after the finished fabric was washed for 5 times; PU coating could be well combined with the finished fabric when the polyester fabric was covered by the hyperbranched macromolecules and the wax water repellent agents except the silicon.
