Abstract

A method for nondestructively determining the diffusion coefficient of solvents in thin fibrous material with strongly anisotropic properties is described. The sought-for coefficient is determined in the absence of a real static characteristic of the converter of the diffusant concentration in the solid phase, which substantially increases the productivity of monitoring.
