Abstract
AbstractTemperature dependent equilibrium dye adsorption data reported for Chlorazol Fast Scarlet 8B, Durazol Red 2B and Chrysophenine G on cotton, CV and CUP fibres and Durazol Grey RG on cotton and CV fibres in the presence of a constant amount of added inorganic electrolyte between 60°C and 90°C, as well as Chrysophenine G on cellophane sheet in the presence of varying amounts of added inorganic electrolyte, between 60°C and 97.5°C, was re‐evaluated using the Williams‐Landel‐Ferry equation. The results obtained suggest that the plasticisation model of dye diffusion appears to offer a reasonable explanation of the temperature dependent equilibrium adsorption of direct dyes on cellulosic fibres/polymers.
