Abstract

Abstract of the Disclosure A three-layered composite barrier fabric has a middle layer of a microporous polyolefin film, in particular polypropylene, and top and bottom layers of spun-bonded polyolefin webs, also preferably made of polypropylene. The three layers are secured to one another by ultrasonic point bonding at spaced-apart points. The middle layer of the composite provides a barrier to liquids such as water or blood while allowing water vapor to be transmitted therethrough. The outer layers provide for strength and overall characteristics of the fabric. The resulting fabric provides breathability by allowing transmission of vapor such as perspiration, consistent with stopping flow of liquid through the fabric. The outer layers provide effective strength and other physical properties to enable their use in protective garments.
