摘　　要：采用中温退浆酶DM-8661对提花毛巾坯巾进行酶氧中温短流程前处理,考察处理温度、处理液pH值、酶浓度、过氧化氢浓度及处理时间对前处理效果的影响,并采用正交试验优化了工艺。结果表明,该坯布酶氧中温短流程前处理优化工艺为:中温退浆酶DM-8661 50 mL/L,30%过氧化氢17.5 mL/L,浴比为1∶40,pH值7,处理温度70℃,处理时间60 min;前处理半制品毛效8.4 cm/30 min,白度82.3,断裂强力317.3 N。相比传统碱氧前处理,其毛效与白度相差不大,而断裂强力损失则小得多。The jacquard towel grey fabric is pretreated with shortened enzyme-peroxide process at medium temperature by en- zyme DM-8661. The influences of treating temperature and time, pH value, concentrations of enzyme and hydrogen peroxide to pretreatment effects are discussed. With orthogonal experiment, the optimum process is enzyme DM-8661 50 mL/L,30% hydrogen peroxide 17.5 mL/L,liquor ratio 1：40,pH value 7,treating at 70 ℃ for 60 min. The results show that the treated fabric has capillary effect 8.4 cm/30 min, whiteness 82.3, and breaking strength 317.3 N under the optimized conditions. Compared with the traditional alkali-peroxide process, the capillary effect and whiteness of the fabric are almost the same, and breaking strength loss is lower.
