Updated: 2019/1/10 16:56:11

Abstract: 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 fabric was 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.


Key words: non-fluorinated water-repellent agent; polyester fabric; fastness to washing; environmental protection
