Environmental pollution is one of the greatest challenged for the world now days. The pollution load coming out from the number of sources like land, water and air pollution. By textile mill is mainly coming out the operation in wet processing. Present developments in Textile Wet Processing aim at over all clean environment. The Textile industry being highly water intensive is a major source of water pollution globally. Many dyes and chemicals used in textile processing remain unused after the absorption of dye in yarn or fabric. In this paper we discuss about the Disperse dyes, i.e. their absorption / exhaustion. Polyester dyeing with disperse dyes has been found to give much higher concentration of polluting substances resulting in greater harmful effects. All these chemicals are very hard to biodegrade and some are toxic too. We have studied other eco-friendly alternatives employing chemicals, which are less polluting and studied their effect on color strength (dye-absorption/exhaustion) and pollution load on different parameters in dye bath. Also discussed about dyeing the polyester dyeing with carrier method and their effect on color strength and comparison of pollution load on the different parameters in dye-bath.
