摘　　要：提出了一种新的生物酶前处理工艺流程,即先氧化漂白后生物酶煮练,对煮练酶、纤维素酶的处理效果,以及氧漂工艺进行试验.结果显示,以下工艺[氧漂双氧水(30%)用量为40～50g/L,pH值10.5,95℃处理1.5 h煮练,煮练酶用量1.0～1.5g/L,pH值8.5,65℃处理1.5 h]的前处理效果最好,且能达到传统的烧碱前处理效果.The new biological enzyme pretreatment process of pure cotton knitted fabric was presented, that is oxygen bleaching prior to bio-enzyme scouring process. The treating effects of scouring enzyme and cellulase, as well as oxygen bleaching process were tested. As a result, the optimal results of pretreatment can be available under the following conditions： 30% hydrogen peroxide 40 - 50 g/L, pH value 10.5, scouring at 95℃ for 1.5h for oxygen bleaching; scouring enzyme 1.0 - 1.5 g/ L, pH value 8.5, 65℃ × 1.5 h for scouring. The pretreatment result with biological enzyme can be reached traditional one with caustic soda.
