Abstract
An article comprising a microporous membrane. A first porous fabric is laminated to a first side of the microporous membrane. A second porous fabric is laminated to a second opposite side of the microporous membrane to form a laminate with the membrane and the first porous fabric. The laminate has two fabric sides separated by the microporous membrane. A treatment material is applied to the laminate to form a treated laminate. The treated laminate has an oil resistance of at least a number 7 determined by AATCC 118 testing on both fabric sides and has an air permeability through the treated laminate of at least 0.01 CFM per square foot determined by ASTM D737 testing.
