应用新型煮练酶SKQ-45的散棉低温煮漂工艺优化
Application of novel scouring enzyme SKQ-45 in low temperature scouring and bleaching for loose cotton and its optimization
摘要
Abstract
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 fol ows: SKQ-45 3.9 g/L, 36% H2O2 6.0 g/L, NaOH 2.0 g/L, bath ratio 1∶40, scoured at 54 ℃ 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.关键词
