摘要
对棉针织物碱精练或酶精练后用过氧乙酸漂白的前处理工艺进行了研究,比较了这两种工艺对白度、强力、润湿时间的影响,优化出相应的工艺参数。结果表明,棉针织物的碱或酶精练的最佳漂白工艺条件基本一致,即过氧乙酸8g/L,焦磷酸钠2g/L,渗透剂DX22g/L,pH值7,漂白温度70℃,漂白时间60min;不同方法精练再漂白后织物的染色效果接近。
Peracetic acid bleaching of cotton knitted fabric scoured with alkali and enzyme individually were carried out. Effects of alkali and enzyme on whiteness, strength, wetting time of the bleached fabric were studied, and the optimum parameters were defined. The results showed that the optimum conditions of enzymatic scouring were similar to that of alkaline scouring, i.e., peracetic acid 8g/L, sodium pyrophosphate 2 g/L, penetrant DX-2 2 g/L, pH value 7, bleaching at 70℃ for 60 minutes. The dyeing effects of cotton fabrics subjected to different preparations were also very close.
