Claims
- 1. A flexible, breathable, non-linting, composite comprising:
- (i) a middle layer of padding, and
- (ii) a top and bottom layer each comprising water impermeable and moisture-vapor-permeable porous film, said top and bottom layers encapsulating said middle layer by sealing the open edges of the top and bottom layers.
- 2. The composite of claim 1 wherein said top and bottom layers each comprise:
- (i) a flexible, water-impermeable, moisture-vapor-permeable, porous film as the external surfaces, and
- (iii) a continuous hydrophilic layer joined to the film said hydrophilic layer having a moisture vapor transmission rate exceeding 1000 gms./m.sup.2 .multidot. day and forming a barrier to passage of liquids wherein the layer (ii) is adjacent to said padding.
- 3. The composite of claim 1 wherein the porous film is porous, expanded polytetrafluoroethylene
- 4. The composite of claim 2 wherein the water-impermeable, moisture-vapor-permeable porous film is porous, expanded polytetrafluoroethylene and the hydrophilic layer is a polyurethane.
- 5. The composite of claim 1 or 2 wherein said middle layer is cotton.
- 6. The composite of claim 1 or 2 wherein said middle layer is foam.
- 7. The composite of claim 1 or 2 wherein said middle layer is polyester.
- 8. The composite of claim 1 or 2 wherein said middle layer is wool.
- 9. The composite of claim 1 or 2 in which the top and bottom layers of porous film define discrete quilt patterns in which the middle layer and top and bottom layers are compressed and bonded along the peripheral boundries of the quilt pattern.
- 10. Wearing apparel containing the composite laminate of claim 9.
- 11. Thermal insulation containing the composite laminate of claim 9.
- 12. An orthopedic immobilizer containing the composite of claim 1.
