Breathable nonwoven liquid barrier fabric and method

摘要

A porous, nonwoven fabric made from bonded fibers and/or filaments is provided, and a continuous film or layer of a liquid radiation curable resin is applied to the fabric surface. The liquid film is subjected to radiation to cure the liquid into a solid film bonded to the surface of the fabric. The film renders the fabric impervious to liquids but allows passage of liquid vapor, and the technique provides an alternative to more expensive ways to achieve the same barrier properties.
