Abstract
An O3 based cleaning process for removing dyestuff residues from the surface of textile dyeing machine was investigated in this study. The objective of this pilot-scale study was to compare the cleaning efficiency of new oxidative method with that of conventional reductive cleaning method containing Na2S2O4 and NaOH. A sample dyeing machine was developed to assess the effectiveness of O3 based cleaning carried out at the end of deep shade reactive dyeings. Pre-dyed and pre-bleached fabric samples processed after conventional and O3 based machine cleanings were compared in terms of change in shade, fastness properties and whiteness degree (%). The new oxidative method appeared to be a promising alternative to the conventional machine cleaning. The results show that similar or better degree of cleaning can be obtained by injecting O3 into the textile dyeing machine. The new process is environmentally acceptable because it does not use any harsh chemicals and requires low quantity of water and energy as opposed to conventional machine cleaning. Wastewater generated in O3 cleaning exhibited reduced pollutant load in terms of COD, pH, electric conductivity, colour and total suspended solids.
