Economic Considerations from the Exhaust Application of Reactive Dyes Under Ultra-low Liquor Ratio Conditions

This paper reports on the investigation of the application of reactive dyes at ultra-low liquor ratios. Various types of reactive dye were included in the study, and it was found that acceptable dyeing results could be obtained by reducing the liquor ratio from the conventional 10:1 to 5:1. The accompanying reduction in electrolyte additions could offer several benefits in both fabric and yarn dyeing
