In order to clarify the meaning of dye diffusion into fibres a new diffusion model is introduced which is a combination of the pore model and the free volume model. Using this model, it is shown that the diffusion coefficient obtained experimentally can be described as a function of dye affinity, swelling of the fibre, glass transition temperature and other factors. The validity of this model is confirmed by comparing the diffusion coefficients obtained experimentally in various systems with those calculated using this model.
