Color fading through ozonation has been previously studied by our and other labs. Although great progress has been achieved in this field, studies for the optimization of the operating process of the ozone water washing process and fabric-touch tests are important for the practical application in industry. An industrial-scale G2 ozone washing machine was used for the color fading of the samples. Since the color fading process factors are interrelated to each other, a specific experimental approach, i.e., orthogonal method, was used in this work. Three process factors used in the industrial scale color fading process, i.e. (i) ozone feed rate; (ii) moisture content in the fabric; and (iii) treatment time, were studied in this paper. Additionally, the color fading and tactility of fabric through ozonation were analyzed Our results show that the three investigated factors have a significant impact on the fading effect, in which the treatment time is the most significant. When using the G2 device for denim washing, the desired color-fading effect could be quickly obtained by adjusting the treatment time at 6.67 g/min of ozone feed rate and 50% of moisture content in the fabric. Finally, the tactile analysis by fabric-touch tester shows that there is no significant change in the total touch feel between the treated samples and the untreated sample.

我们和其他实验室先前已经研究了通过臭氧氧化褪色的方法。尽管在该领域已经取得了很大的进步，但是优化臭氧水洗涤过程的操作过程和织物触感测试的研究对于工业上的实际应用是重要的。工业规模的G2臭氧清洗机用于样品的褪色。由于褪色过程因素相互关联，因此在这项工作中使用了一种特定的实验方法，即正交方法。工业规模褪色过程中使用的三个过程因素，即（i）臭氧进料速度；（ii）织物中的水分含量；（iii）治疗时间，在本文中进行了研究。另外，结果表明，所研究的三个因素对褪色效果有显着影响，其中处理时间最显着。当使用G2装置进行牛仔布洗涤时，可以通过将处理时间调整为6.67 g / min的臭氧进料速度和50％的织物水分来快速获得所需的褪色效果。最后，织物触觉测试仪的触觉分析表明，在处理过的样品和未处理过的样品之间，总的触感没有明显变化。通过将处理时间调整为臭氧进料速度为6.67 g / min，织物中水分含量为50％，可以迅速获得所需的褪色效果。最后，织物触觉测试仪的触觉分析表明，在处理过的样品和未处理过的样品之间，总的触感没有明显变化。通过将处理时间调整为臭氧进料速度为6.67 g / min，织物中水分含量为50％，可以迅速获得所需的褪色效果。最后，织物触觉测试仪的触觉分析表明，在处理过的样品和未处理过的样品之间，总的触感没有明显变化。
