Abstract

Available and clean water resources in the world are decreasing day by day. Textiles is one of the industries that are consuming the highest volumes of water. For this reason, it is necessary to develop environmentally friendly textile processes within the scope of sustainability. Reactive dyeing is followed by a washing process consisting of many steps to remove unfixed/hydrolyzed dyes, which is the most preferred dyeing in the coloring of cotton products. A high amount of water is consumed in these processes. In this study, an alternative washing process was developed instead of the conventional reactive washing process. The baths, which were decided to be used according to the transmittance values of the washing baths after dyeing in light, medium, and dark shades, were used again as the first two baths of the next washings. Alternative washing did not have a negative effect on the quality parameters, namely washing and rubbing fastnesses. As a result, it was observed that the last two baths of the washing cycle could be used as the first two baths of the next washing cycle. In this case, it was predicted that approximately 40%−50% water savings could be achieved. Graphical abstract

环境友好型活性洗涤工艺:一个案例研究

世界上可用的清洁水资源日益减少。纺织业是耗水量最高的行业之一。因此，有必要在可持续发展的范围内开发环保纺织工艺。活性染色之后是洗涤过程，该过程包括许多步骤以去除未固定/水解的染料，这是棉制品着色中最优选的染色。在这些过程中消耗了大量的水。在这项研究中，开发了一种替代洗涤工艺，以取代传统的反应洗涤工艺。根据洗涤浴在浅色、中号和深色染色后的透射率值决定使用的浴，再次用作下一次洗涤的前两个浴。交替洗涤对质量参数，即洗涤和摩擦牢度没有负面影响。结果，观察到洗涤循环的最后两个浴可以用作下一洗涤循环的前两个浴。在这种情况下，预计可以实现大约40%-50%的节水。图形摘要
