The dyeing rate of p-aminoazobenzene on nylon 6 yarn at 40°C has been investigated. The apparent diffusion coefficient and the diffusional boundary layer parameter are estimated in such a way that the experimental data fit with the theoretical rate curve based on the diffusional boundary layer model. The dyeing behavior of the yarn is discussed in relation to the pore size of the spaces between individual filaments.
