  • Breathable waterproof fabrics with a dyed and welded microporous layer
    Patent number: 8470722
    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 m3/m2/min and about 7.6 m3/m2/min, and an MVTR per ASTM E-96B method of greater than about 500 g/m2/day. The nanofiber layer is dyed over at least a portion or all of its surface or both.

  • Fine-fiber nonwoven-supported coating structure
    Patent number: 7998885
    Abstract: This invention relates to a liquid penetration-resistant water-vapor-permeable multi-layer composite material and process for making the same comprising a porous nanofiber web of polymeric fibers, wherein the polymeric fibers of the nanofiber web have a diameter of less than 1000 nanometers and wherein the nanofiber web has a basis weight of 5 to 40 grams per square meter and a surface roughness (?RMS) of 5 to 15 micrometers and where, the porous nanofiber web is coated on a surface with a layer of water-vapor-permeable, hydrophilic, monolithic, water transport material.

  • Wind resistant and water vapor permeable garments
    Publication number: 20110092122
    Abstract: An article of apparel having the ability to maintain a high MVTR while protecting the wearer from wind. The garment has a nanofiber layer bonded to, and in a face-to-face relationship with a fabric outer layer. Optionally a second fabric layer is bonded adjacent to and in a face-to-face relationship with the nanofiber layer and on the opposite side of the nanofiber layer from the first fabric layer. The fabric has a Frazier air permeability of no greater than about 7.6 m3/m2/min, and an MVTR of greater than about 500 g/m2/day.
