THE APPLICATION of various permeability tests to textiles and textile materials has been a practice in the industry for a number of years, and the determinations of densities and total porosities have long been subjects of interest in this field. Sieminski and Hotte [13] ] have pointed out that the distinction between the terms porosity and pervvceability has not at all times been appreciated. Porosity of a textile fabric pertains to the total volume of void space contained within its boundaries, whereas permeability refers to the accessibility of the void space to the flow of a gas or a liquid. Porosity is usually defined as the ratio of the void space to the total volume encompassed by the boundaries of the material. Permeability is an empirical value, usually expressed as a rate of flow of some liquid or gas per unit area of fabric, and is a function of, among other variables, the differential pressure. These two properties of a fabric are thus quite different, and the relationship that exists between them is likely to be complex. The total porosity of a fabric can be visualized as
