A non-slip, waterproof, water vapor permeable fabric and method of making are described. The fabric is made by obtaining a waterproof, water vapor permeable film and adhering one side of the film to a layer of fabric which may be a stretch fabric. The other side of the film is provided with a discontinuous coating of an elastomer which has an elastic modulus of less than 5.5N/mm.sup.2. The discontinuous coating may take various forms including a pattern of dots or a grid of intersecting lines. The discontinuous coating may optionally project above the surface of the film. The presence of the discontinuous coating of elastomer results in a fabric with a static coefficient of friction of greater than about 1.0 on the discontinuously coated side of the fabric. The film is preferably a porous expanded polytetrafluoroethylene film provided with a hydrophilic coating on one surface; the hydrophilic coating may serve as an adhesive for joining the one surface of the film to the layer of fabric. The inventive fabric is useful for various applications such as articles of medical protective clothing including surgical drapes and liners for orthotic braces, which applications may benefit from the non-slip character of the fabric.
A non-slip, waterproof, water vapor permeable material comprising a film of porous expanded polytetrafluoroethylene having first and second opposing surfaces, wherein said first surface is provided with a discontinuous coating of an elastomer and said first surface with the discontinuous coating of the elastomer has a static coefficient of friction greater than about 1.0, and wherein said second surface is adhered to a layer of fabric.
A non-slip, waterproof, water vapor permeable material comprising a layer of fabric having first and second opposing surfaces wherein the first opposing surface is laminated to a layer of porous expanded polytetrafluoroethylene and the second opposing surface is provided with a discontinuous coating of an elastomer, wherein the second opposing surface of the fabric having the discontinuous coating of the elastomer has a static coefficient of friction greater than about 1.0.
