Textile processing is one of the largest and oldest industries worldwide and is responsible for substantial resource consumption and pollution. This paper discussed two approaches (Process-I and Process-II) towards the conservation of water in the wet processing of cotton fabric. In these new approaches, the surface of cotton yarn and fabric was modified using a resin followed by dyeing using disperse dye. In these new approaches, there is no need for pretreatment of the cotton fabric before dyeing which can save a significant amount of water, energy, and other chemicals along with cost benefits. A solid dyeing effect has been achieved on cotton fabric using Process-I. Process-II provided a denim fading look on the cotton fabric.
