Mechanism of drying thick porous bodies during the falling‐rate period: II. A hygroscopic material

Abstract

AbstractA further analysis of the second falling‐rate period in the drying of thick highly porous textile structures is made, this time in the case of drying wool, special attention being paid to the adsorbed water held by the wool in the air‐dry region. As the solid‐to‐void ratio is low, the quantities of adsorbed water are small and have little effect on the general equilibrium. Values of thermal conductivity are calculated for wet wool.
