The contact resistance behaviors of the fabrics during the water transmission process were investigated by measuring: (1) the contact resistance between the fabric settled on a metal cylinder, to which a fixed amount of water was supplied, and the sample fabrics during the water transmission process, (2) the contact resistance between the metal cylinder and the wet sample fabrics during the drying process, and (3) the stress acting on the wet fabrics during the drying process at a fixed strain under about 1.5%. The contact resistance showed a minimum, and increased during the falling rate period of drying, ranging approximately between 0.1g/cm
2 and 1g/cm
2. These changes were more remarkable with hydrophilic fabrics, particuraly with silk, than with hydrophobic fabrics. The wet fabric stress increased during the falling rate period, apparently due to contraction force. The relationship between the capillary adhesion force and the geometrical amount of water was calculated by using the derived plane model. The capillary adhesion force increased with decreasing geometrical amount of water. The dependence of the capillary adhesion force, the stress and the frictional coefficient on the contact resistance were also estimated by introducing the stress factor to the derived equation. The experimental results could be qualitatively interpreted in terms of the above mentioned equation.
