Substitution of conventional chemicals by ozone at textile finishing

Ozone is an environmentally friendly gas which is widely used in drinking water treatment plants. In this study, ozone utilized in the finishing processes, especially for viscose and polyester fabrics. Thereby reducing environmentally harmful waste, as well as an innovative energy-saving ozone process technologies are developed. For this purpose, a sample fabric dyeing machine (jet) of 1 kg capacity is equppied with ozone feeding systems. This prototype is tested for viscose bleaching, afterclearing of disperse dyed polyester, afterclearing of reactive dyed viscose. Process optimization is conducted on this prototype. With innovative technology; water, energy, time savings and the reduction of environmental load are provided. This study is projected "Ozone utilization in a textile finishing plant" San-Tez Project. So all experimental works performed in the Akbaşlar Textile Dyeing Printing Factory. Key Words: Ozone, finishing process, viscose, polyester, bleaching, washing
