ABSTRACT:
Breathable barrier fabrics are made by sizing a substrate, made of bonded fibers forming void spaces therein, with a film-forming material that fills the voids of the substrate to form a solid film between the fibers. The resulting non-porous breathable material provides a high strength fabric which is permeable to water vapor, such as body moisture, but impermeable to air and aqueous liquids. The non-porous breathable barrier fabric acts as a barrier against wind, dust or other airborne contaminants, e.g. bacteria, viruses, pesticides, etc., as well as against aqueous liquids such as blood. Alternatively, porous barrier fabrics can be made by incorporating air into the film-forming filler material to obtain greater comfort at lowered barrier qualities. The barrier fabrics of the invention are suitable for industrial, hospital and other protective covering uses.
