A study was made of the influence of temperature on the kinetics of the desorption of disperse dyes on polyester of dif ferent deniers. Activating energies were determined and, from the theory of absolute rates, related to both diffusion and kinetics, we measured the activating free energies and the activating entropies. Similar results were obtained for both.
