摘要
纯棉高支织物前处理中使用生物酶,以实现无碱清洁生产。探讨了几种前处理工艺的半制品质量指标和废水指标。结果表明,采用氧退漂-生物酶冷堆-热水洗工艺对纯棉高支轻薄织物进行前处理,半制品白度81.39%,毛效8.2 cm/30 m in,强力损伤率5.8%,尤其是强力保留率较高。该工艺通过冷堆完成,实现了无碱前处理,大幅降低了能耗和水耗,减少了排污量及废水处理难度。
Enzyme is applied to pretreatment of high counts cotton fabrics to realize alkali free clean production.Quality indexes of semi-products and wastewater indexes of different pretreatment processes are discussed.The results show that the high counts cotton fabrics pretreated with peroxide desizing and bleaching,enzyme cold pad batch,hot washing process have the whiteness of 81.39%,capillary effect of 8.2 cm/30 min and lower strength loss of 5.8%.The pretreatment process with cold pad batch method can realize alkali free pretreatment,cut down water and energy consumption,and reduce wastewater discharge and burden on wastewater treatment.
