Innovations and modifications are the continuous processes of wet processing technology in clothing and textile industries. Due to inadequacy of water resources, consumer demands, other environmental and commercial issues, a lot of research works are being carried out throughout the world to develop the eco-friendly and cost effective textile dyeing mechanism. In this research, an attempt was taken to develop efficient dyeing method of widely used cotton and polyester blend knitted fabric by the simple modification of recognized two bath cotton/polyester blend dyeing process. The main goal of this study was to find out an alternative dyeing process to reduce the water consumption, process time and production cost replacing conventional dyeing process. In this regard, the pre-treatment and dyeing process of cotton/polyester blend fabric were modified and reduction-clearing process was eliminated without applying any extra wash off chemicals. The results revealed outstanding efficiency in terms of process time, water consumption and cost minimization maintaining all quality parameters as required. By applying modified process, the water consumption was reduced approximately by 26 %, power consumption and processing time by 15 %, and steam consumption by 3.6 %, thus overall production cost by 8 %. The proposed method could be applied to cotton/polyester knitted fabric dyeing regardless of construction, blend ratio, color, and shade %.
