  • Breathable waterproof fabrics with a dyed and welded microporous layer
    Publication number: 20080108263
    Abstract: A composite wind barrier fabric having the ability to maintain a high MVTR while controlling air permeability. The fabric has a nanofiber layer optionally welded to, and in a face-to-face relationship with, a fabric layer. Optionally a second fabric layer is welded adjacent to and in a face-to-face relationship with the nanofiber layer and on the opposite side of the nanofiber layer to the first fabric layer. The fabric has a Frazier air permeability of no greater than about 25 cfm/ft2, and an MVTR per ASTM E-96B method of greater than about 500 g/m2/day. The nanofiber layer is welded to the fabric layer over a portion of its surface.
