Superiority of Sustainable Ozone Wash Over Conventional Denim Washing Technique

Abstract

Denim jeans need to be wet-processed in order to create a comfortable feel and a versatile look in the end product. The use of Ozone to finish denim jeans offers environmental and economic benefits by reducing rinse periods, water use, and energy consumption. Ozone is a specialized oxidant with a strong oxidation potential and can decolorize textile effluents, and it has a particular affinity for indigo. This paper will demonstrate why Ozone-based denim wash should be recognized as sustainable in different aspects of denim washing. The study observed that denim fabric finishing with Ozone particles has reduced garments processing time and requires less water and chemicals than the Conventional finishing method. Moreover, because of the low use of chemicals and water, ozone-based finishing produces a minimal amount of wastewater which eventually has less impact on the ETP as well as less effect on the environment than the traditional denim washing method. Also, it gives two times more production than conventional. With an in-depth evaluation of different washing points, this paper has concluded that Ozone-based wash is a promising finishing treatment for denim products.
