Transport phenomena of C.I. Direct Red 2 into water-swollen cellulose membranes have been studied at 55 °C. We reasoned that the dye has a high affinity on cellulose. The transport phenomena were analyzed on the basis of a parallel transport theory of surface and pore diffusion. The transport of the dye into a cellulose membrane was characterized and factors that affect the pore diffusivity of the parallel diffusion model were considered by comparing stimulated data.
