Equilibrium adsorption isotherms and rates of dyeing at various temperatures for Chlorazol Sky Blue FF (C. I. Direct Blue 1, sodium salt) on viscose rayon fibres in the presence of electrolytes having different water structure breaking/making properties have been measured. The results clearly show that variations in water structure around the hydrophobic parts of the adsorbing dye molecules and around the adsorbent fibre surface influence the dye–binding process.
