Abstract
A stretchable, drapable, windproof, water resistant and water vapor permeable composite fabric including an inner layer of fabric, a polyurethane barrier and an outer layer of fabric. The barrier is constructed to allow water vapor molecules to travel therethrough, but restricts the passage of wind and liquid water. The water vapor is transported to and travels through the barrier to the outer fabric layer where it is removed to the environment.
Claims39
A stretchable, drapable, water vapor permeable, windproof and water resistant composite fabric for use in a garment comprising:
- an outer layer of fabric;
- an inner layer of fabric;
- barrier means for providing resistance to wind and liquid water while providing for water vapor transport through absorption-diffusion-desorption including a hydrophilic barrier layer disposed on and adhered to at least one of said inner or outer layers of fabric by transfer coating from a carrier without a separate adhesive;
- and
- said other of said inner or outer layers of fabric being disposed on and adhered to said barrier layer.
A stretchable, drapable, water vapor permeable, windproof and water resistant composite fabric for use in a garment comprising:
- an outer layer of fabric;
- an inner layer of fabric;
- and
- barrier means for providing resistance to wind and water while providing for water vapor transport, including a microporous hydrophobic polyurethane barrier layer disposed on and adhered to one of said inner or outer layers of fabric by transfer coating from a carrier without a separate adhesive;
- said other of said inner or outer layers of fabric being disposed on and adhered to said barrier layer.
A method of forming a stretchable, drapable, water vapor permeable, windproof and water resistant composite fabric, comprising the steps of;
- adhering a barrier layer on one side of one of an outer or inner layer of fabric by transfer coating without using an additional adhesive, said barrier layer being selected from the group consisting of a hydrophilic material, a hydrophobic polyurethane material and a combination thereof;
- and
- adhering the other of the inner and outer layers of fabric to said barrier layer to form said composite fabric.
