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 between about 1.2 m/m/min and about 7.6 m/m/min, and an MVTR per ASTM E-96B method of greater than about 500 g/m/day. The nanofiber layer is dyed over at least a portion or all of its surface or both.
