精纺毛/涤面料表面化学改性与拒水整理协同超拒水工艺探究

Superhydrophobic worsted wool fabrics produced by surface chemical modification and repellent finishing

通过对精纺毛/涤面料进行表面化学改性和拒水整理,最终协同实现超拒水效果。首先采用二氯异氰尿酸钠和过硫酸钠等氧化试剂对精纺毛/涤面料表面进行化学改性,得到了对精纺毛织物表面进行化学改性的最佳工艺:二氯异氰尿酸钠∶过硫酸钠质量比为1∶1,改性时间60 min,改性温度50℃;对改性后的精纺毛/涤面料进行拒水整理,在整理剂C6助剂(Oleophobol TMCP-SLA)10%(owf),浴比1∶10,温度30℃,浸渍15 min的条件下,最终精纺毛/涤面料的拒水接触角可以达到151°,达到超拒水效果。

This article studies the superhydrophpbic worsted wool fabrics produced by surface chemical modification and repellent finishing. Firstly, using sodium dichloroiscocyanurat and sodium persulfate which have a certain oxidizing to modified the surface of worsted wool fabrics,and getting the best method to modified the surface of worsted wool fabrics： sodium dichloroiscocyanurat ： sodium Persulfate = 1： 1, modification time 60 min, modification temperature 50 ℃. Then repellent finishing of worsted wool fabric was adopted. Under the condition that the finishing agent C6 additives （OleophobolTMCP - SLA） 10% （owf）, bath ratio 1：10, temperature 30℃, dipping 15 minutes, eventually rejected water contact angle of worsted wool fabric can reach 151°, obtained the very good super waterproof effect.
