Moisture diffusion in paper is characterized by diffusivities in the pore space and fiber matrix (Dp and Dq). These were estimated for paper sheets from steady state moisture flux measurements. Lateral (xy) diffusion was higher than diffusion in the transverse (z) direction. The diffusivity in the void space was inversely proportional to the refining level of the pulps. However, no significant effects were found on the condensed moisture diffusivity and on the sorption isotherms.
