摘　　要：采用一种新型复合酶制剂——双氧水低温催化煮练酶KQ-45(SKQ-45)对散棉进行低温煮漂处理,在单因素分析的基础上讨论了SKQ-45用量、煮漂温度和时间对散棉断裂强力及白度的影响及优化范围,然后利用3因子2次通用旋转组合设计对SKQ-45低温煮漂工艺进行优化,并将优化数据在DPS数据处理系统中运行分析,从而得到SKQ-45煮漂的优化工艺:SKQ-453.9g/L,36%H_2O_26.0g/L,NaOH2.0g/L,温度54℃,时间55min,浴比1∶40。经优化工艺处理的散棉白度达到了63.40%,高于高温碱煮漂工艺;煮漂后断裂强力及染后2次断裂强力分别为1774.56和1599.64cN,较高温工艺分别提高了67.30%和100.34%;染色散棉的K/S值及固色率较高温工艺分别提高了11.54%和9.32%。因此,SKQ-45优化工艺的煮漂效果比高温工艺更好。Low temperature scouring and bleaching processes for loose cotton were carried out with scouring enzyme KQ-45 （SKQ-45）, a type of novel low temperature catalytic auxiliary for hydrogen peroxide. Based on single factor analysis, the effects and optimization range of SKQ-45 dosage, temperature and time on the bundle strength and whiteness of loose cotton were discussed. The low temperature process with SKQ-45 was optimized by three-factor quadratic general rotary unitized design, and the experimental data was analyzed in DPS data processing system. The optimum process was determined as follows： SKQ-45 3.9 g/L, 36% H202 6.0 g/L, NaOH 2.0 g/L, bath ratio 1：40, scoured at 54 ~C for 55 min. The whiteness of loose cotton treated by the optimal process was 63.40%, which was higher than the high temperature alkali scour- ing and bleaching process. The bundle strength after scouring and dyeing was 1 774.56 and 1 599.64 cN, which increased 67.30% and 100.34% than the high temperature process, respectively. The K/S value and the fixation rate of dyed loose cotton increased 11.54% and 9.32%, respectively. Accordingly, the souring and bleaching result of SKQ-45 process was better than the high temperature process.
