Rinsing of Cotton Fabric by Ozonation after Reactive Dyeing Procedure
Abstract:
Rinsing of cotton fabric dyeing with reactive dye was carried out by ozonation process. The results indicated that ozonation rinsing is adequate to achieve washing and rubbing fastness results comparable with conventional soaping without significant colour yield losses and colour differences. The rinsing wastewater could be simultaneously decolorized and degarded during the ozonation rinse procedure. Ozonation rinsing could take advantages of saving water, energy and time as it was performed at 50 °C for 3-7 min with a short process, and decreasing environmental load as it avoids the use of organic detergent used in conventional soaping.
