The experimental and theoretical air permeabilities of twelve multilayered. needle punched
nonwoven samples are compared in this paper. Samples are made from ceramic and glass
with varying layer structures. The density and diameter of all fibers used to make individual
webs are approximately the same, and so the fabric samples made from these webs are
assumed to be homogeneous, multilayered structures. The porosity of all fabric structures is
greater than 0.96. Thus, the theoretical air permeability is based on a modified Kozeny
equation. Experimental measurements involve the Frazier air permeability tester.
