摘　　要：为了解决机械摩擦导致的针织物表面光洁度和成品外观差的问题,采用酸性纤维素酶对靛蓝针织牛仔面料进行处理,对正交设计试验方案处理后的织物毛羽分布情况、织物顶破强力、失重率等性能指标进行测试。试验结果表明:在毛羽长度0~0.2 mm、0.2~0.4 mm、0.4~0.6 mm 3个范围测试中,织物毛羽指数最小、表面最光洁的处理工艺为:处理温度50℃,酸性纤维素酶质量浓度1.8 g/L,pH值为4,处理时间60 min。影响顶破强力的因素主次排列为:pH值>酸性纤维素酶质量浓度>处理温度>处理时间,顶破强力损失最小的方案为:处理温度40℃,酸性纤维素酶质量浓度1.2 g/L,pH值为5,处理时间60 min。在平磨试验中,处理温度对织物质量损失影响最大,最优方案为:处理温度50℃,酸性纤维素酶质量浓度1.2 g/L,pH值为6,处理时间30 min。With the aim of solving the problem of poor surface finish and finished product appearance of knitted fabrics caused by mechanical friction.Acid cellulase was used to treat indigo knitted denim,and the performance indexes such as fabric hairiness distribution,fabric top breaking strength and weight loss rate were tested after the treatment with orthogonal design test scheme.The results show that in the three ranges of hairiness length 0-0.2 mm,0.2-0.4 mm,0.4-0.6 mm,based on smallest fabric hairiness and the most smooth surface,the optimal treatment process was 50℃ temperature,enzyme dosage of 1.8 g/L,pH value was 4,treatment time was 60 min.The factors that affect the bursting strength were:pH value>enzyme dosage>treatment temperature>treatment time,the processing conditions to obtain minimum loss of the bursting strength was:40℃ treatment temperature,enzyme dosage was 1.2 g/L,pH value was 5,the treatment time was 60 min.In the grinding test,the treatment temperature had the greatest effect on the weight loss of the fabric.The optimum treatment was as follows:the treatment temperature was 50℃,the concentration of acidic cellulose was 1.2 g/L,the pH was 6,and the treatment time was 30 min.
