The influence of mixtures of electrolytes on the adsorption of Chlorazol Sky Blue FF on viscose fibres

Abstract

Equilibrium adsorption isotherms and rates of dyeing for Chlorazol Sky Blue FF on viscose fibres in the presence of lithium, sodium and potassium chlorides, singly and in binary mixtures, have been measured. In the presence of the single electrolytes dye adsorption and rates of dyeing at constant electrolyte concentration increase in the order LiCl<NaCl<KCl. In mixtures of these electrolytes, however, the cation with the greater ability to disrupt the structure of water considerably enhances the ability of the other cation to influence dye adsorption and dyeing rates.
