Abstract
It is necessary to know the details of mechanical action in washing process of textile fabrics for obtaining better effect. Several factors of intricacy in analysis of washing process depend on the peculiar geometrical structure of textile fabrics. Relation between liquid flow behavior and pore structure of twelve sorts of fabrics was examined.
It was confirmed that permeation of water and n-hexane in these fabrics is expressed in principle by modified by Poiseille's law and penetration of both fluids by Washburn's equation. The caluculated pore radiis by experimental data of permeation and of penetration are balanced with pore radius determined by mercury intrusion method. The cause of mutual little discrepancy in the caluculated pore radii and the constant of velocity gradient m between these fluids was discussed.
