Directional Permeability in Homogeneous Nonwoven

A new general model of the directional permeability in homogeneous anisotropic nonwoven structures is presented It is based on drag-force theory and D'Arcy's Law Structural parameters in the fabric are considered including fibre diameter porosity and the fibre-orientation distribution The governing equations of the local permeability in two- and three-dimensional structures are derived
