Abstract:
A method of making an article having an improved oleophobic property. The method includes the step of providing a microprous membrane. The method also includes the step of laminating a porous fabric to the microporous membrane to form a laminate with a membrane side and a fabric side. A treatment material is applied to the laminate to provide a treated laminate. The treated laminate has an oil resistance property of at least a number 7 determined by AATCC 118 testing on both the membrane side and the fabric side. The laminate also has an air permeability therethrough of at least 0.01 CFM per square foot determined by ASTM D737 testing.
