棉织物退煮漂汽蒸一浴工艺

摘要

针对传统棉织物前处理工艺流程长，能耗高，用工多等问题，采用碱堆置加退煮漂汽蒸一浴工艺对棉织物进行前处理，并对煮练后的半制品进行性能测试．结果表明，碱液中氢氧化钠5g/L、煮练液中高效短流程精练剂30g/L、过氧化氢8g/L、pH10.9，煮练后半制品毛效10cm/30min 、白度82％、强力623N、棉籽壳0个，能满足后续染整加工要求．解决了生产中出现的粘辊及产品中出现的蜡条、破洞和色深等问题．%The traditional cotton fabric pre-treatment has long process ,high energy consumption and em-ployment issues ,to solve these issues ,desizing scouring and bleaching one-both pretreatment of cotton fabric were carried out ,and the performance of semi-finished products after scouring was tested .The re-sults showed that sodium hydroxide 5g/L ,highly efficient shortened scouring agent 30g/L ,hydrogen peroxide 8g/L ,pH 10.9 ,scouring fabric capillary efficiency 10cm/30min ,w hiteness 82% ,strength 623N . cotton seeds 0 .And the solutions for common adhesive ,waxes ,hole and colour dark were advanced .
