棉盖丙复合针织物的次氯酸钠处理

Treatment of double jersey with cotton face and polypropylene back by sodium hypochlorite

优化次氯酸钠处理丙纶的条件,即:NaC lO(有效氯)1.5 g/L,pH值3,浴比1∶20,温度20℃,时间45 m in,用碱性染料对氯化丙纶进行染色。此优化条件能对棉盖丙复合针织物的棉组分进行良好的前处理;用活性染料/碱性染料及活性/分散染料同浴对复合针织物进行染色,染色效果良好。

The optimal chlorination process of polypropylene with sodium hypochlorite is： the dosage of sodium hypochlorite is 1.5 g/L, pH value 3, liquor ratio 1 ： 20,temperature 20 ℃ and time 45 min. The treated double jersey with cotton face and polypropylene back was dyed with reactive/disperse and reactive/basic dyes in the same bath and good dyeing results is gained.
