摘要
针对亚麻/棉织物前处理过程中强力损失较大、能耗高等难题,采用冷轧堆工艺取代常规前处理工艺。考察了不同工艺对亚麻棉织物强力损失、麻皮残留数量和白度的影响。结果表明,织物采用先碱氧冷轧堆工艺煮漂处理,再进行氧漂的前处理工艺,织物强力下降最少,白度与常规工艺相当,麻皮残留少。优化的煮漂冷轧堆工艺条件为:30%双氧水40 g/L,活化剂10 g/L,冷堆时间24 h。
Owing to high strength loss and energy consumption in conventional pretreatment process of linen cotton fabric, cold pad-batch process is carried out. Effects of various processes on strength loss, bast residual and whiteness are studied. The results show that blended fabric pretreated with alkali-peroxide cold pad-batch process firstly and followed by peroxide re- bleaching process features less strength loss and the similar whiteness, compared to those of conventional process, The optimized cold pad-batch process for scouring and bleaching is dwelling for 24 h with hydrogen peroxide（30%） 4 g/L and the activator 10 g/L.
