摘要
针对传统棉织物冷轧堆漂白法耗时长和耗碱高等问题,研究H2O2/NOBS活化体系在纯棉织物冷轧堆漂白中的应用。通过单因素试验和正交试验法分析各工艺因素对漂白效果的影响,探讨其作用原理,开发了整套的应用工艺技术。合适的工艺条件为:H2O2质量浓度30 g/L,NOBS与H2O2物质的量比1∶4,NaOH质量浓度6 g/L,堆置时间6 h。结果表明:该活化漂白工艺在改善漂白织物品质的前提下能够大大减少耗碱量,缩短冷轧堆时间,具有生态环保和高效节能的优势。
Aiming at the problems existing in traditional cold pad-batching bleaching such as long dwell time and high consumption of alkali, application of H2O2/NOBS activating system in cotton fabric cold pad-batch bleaching is proposed. The influence of process conditions on the bleaching effect was investigated through single factor analysis and orthogonal experiments, and the activating bleaching mechanism was discussed. And complete application technology of H2O2/NOBS activating bleaching has been developed. The optimal conditions are as follows： H2O2 concentration, 30 g/L; the mol ratio of NOBS to H2O2, 1：4; NaOH mass concentration, 6 g/L; piling time, 6 h. The results show that the activator bleaching process has the advantages of improving the quality of the bleached fabric, eco-friendly and energy-saving. It remarkably decreases alkali consumption and shortens the piling time.
