Kinetics of convective drying of fibre materials based on solution of a diffusion equation

The calculated kinetic curves of convective drying for the moisture, rate, and acceleration of drying are proposed based on the solution of a diffusion equation. The results of the calculation with the equations obtained are compared with the experimental data for convective drying of fibre materials: cotton and viscose fibre and cotton cloth. The universality of the character of the equation of the dimensionless rate of drying as a function of criterion E (dimensionless time of the process) was demonstrated, and this allows generalizing the experimental data on drying of fibre materials.
