摘　　要：由于海藻纤维不耐强碱,采用煮练酶JN-600和双氧水对海藻纤维/棉混纺针织物进行前处理,探讨了煮练酶和双氧水质量浓度、练漂温度和时间等工艺条件对织物毛效、白度和顶破强力的影响,优化的生物酶前处理工艺为:煮练酶JN-600 2.0 g/L,双氧水7 g/L,处理温度80℃,时间50 min。处理后的海藻纤维/棉混纺针织物的平均毛效为12.4 cm/30 min,白度为86.7,顶破强力为461.4 N。In view of poor alkali resistance of alginate fiber, pretreatment of alginate fiber/cotton knitted fabric with enzyme JN-600 and hydrogen peroxide are carried out. The effects of concentration of enzyme and hydrogen peroxide, bleaching temperature and time on the capillary, whiteness and bursting strength of alginate fiber/cotton knitted fabrics are studied. The optimal process is： enzyme JN-600 2.0 g/L, hydrogen peroxide 7 g/L, pretreatment at 80 ℃ for 50 min. The treated knitted fabric features the capillary of 12.4 cm/30 min, the whiteness of 86.7 and bursting strength of 461.4 N.
