We have investigated the concentration distribution of p-aminoazobenzene in lam inate slabs of fabric and film. Because the diffusional boundary layer exists on multiple layers of fabric, a ternary laminate slabs model is used to describe diffusion behavior. Heterogeneity at the phase interface makes it necessary to modify the partition coef ficient between fabric and film, so that a fit can be obtained between the observed and calculated curves.
