臭氧微纳米气泡技术在棉织物退浆中的应用

Application of ozone micronano bubble technology in the desizing of cotton fabrics

探讨臭氧微纳米气泡技术在棉织物冷轧堆退浆中的应用及工艺优化。通过测试织物的退浆等级、拉伸强力、毛效、白度等评价水洗效果。改变臭氧流量、温度、时间等因素确定优化水洗工艺。结果表明,臭氧微纳米气泡退浆的优化工艺为:臭氧流量0.5 L/min,温度70℃,时间40 min,氢氧化钠质量浓度25 g/L。与常规冷轧堆退浆相比,臭氧微纳米气泡技术可以显著降低退浆温度,缩短处理时间,降低生产成本。

The application and optimization of ozone micronano bubble technology in desizing cotton fabric by cold padbatch were discussed. The washing effect was evaluated by testing desizing grade, tensile strength, capillary effect and whiteness. Change the ozone flow rate, temperature, time and other factors to determine the optimized washing process. The results showed that the optimized process of ozone bubble desizing was: ozone flow 0.5 L/min, temperature 70 ℃, time 40 min, sodium hydroxide 25 g/L. Compared with conventional cold padbatch, desizing temperature, ozone micronano bubbles could significantly reduce the desizing temperature, shorten the processing time and reduce the production cost.
