Sodium chloride and trisodium citrate have been studied as exhausting agents for dyeing bleached cotton fabrics with reactive, direct and solubilised vat dyes. The effect of dye concentration, exhausting agent concentration, dyeing time and temperature were studied and the resulting shades obtained by dyeing with trisodium citrate and sodium chloride were compared. Dye uptake values were estimated and found to be higher for trisodium citrate than for sodium chloride. The total dissolved solids content of the spent liquors was lower with trisodium citrate than with sodium chloride.
