摘　　要：采用生物酶轧堆法对纯棉坯布进行前处理，筛选出较佳的工艺条件为：淀粉酶用量6g／L，果胶酶24g／L；退煮漂一步法和退煮＋漂白两步法复合酶pH值为6～7，处理时间为16h；退浆、精练、漂白三步法中淀粉酶退浆pH值为6～7，退浆时间5—6h，果胶酶精练pH值为8～9，精练时间7～9h。将处理后的织物用涂料轧染染色，其织物的染色深度、匀染性和色牢度等方面均能达到常规前处理的染色效果。Cotton grey fabric was pretreated with enzyme pad-batch process, and the optimized conditions were selected as follows： amylase 6 g/L, pectinase 24 g/L, treating at pH value 6 for 16 h at one-step process of desizing-scouring-bleaching and two-step process of desizing-scouring ＆ bleaching; in three-step process of desizing, scouring and bleaching, desizing with amylase at pH value 6 -7 for 5 -6 h, scouring with pectinase at pH value 8 -9 for 7 -9 h. The treated fabric was dyed with pigment pad dyeing process, and the same effects of dyeing depth, evenness and fastness were obtained compared with conventional dyeing process.
