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.

Availability of water for dyeing and treatment of effluent are two major problems that Indian textile processing industry facing difficult to resolve. Consumption of water in dyeing of cotton using reactive dye is very high. In the present study, fabric samples were modified using different concentrations of resin. These modified samples were dyed with disperse dye using carrier dyeing process. The presence of resin on the surface of fabric was confirmed using FTIR technique. Digital image processing (DIP) method has shown the resin treated fabric surface became smoother than untreated cotton fabric. ANOVA study indicated that there was a strong relationship between resin percentage on fabric and colour value (K/s). The colour durability of dyed samples was also studied. These samples were also analyzed for tensile, tear, crease recovery angle and colour fastness properties.
