A study on the exhaustion of reactive dyes as an influence factor on the colour of reactive dyeing wastewater

Abstract

One of the most significant pollution factors in the dyeing of textile materials is the colour of wastewater. This feature is particularly pronounced as the dye exhaustion is low. This paper examines the exhaustion of 5 reactive dyes, dyes which are widely used and characterized by modest capacity of exhaustion. The exhaust capacity is analysed in correlation with the value of the liquor ratio and the dye concentration in the dyeing solution.
