Abstract
Fabrics made for watersports and outerwear apparel, tents, sleeping bags and the like, in various composites, constructed such that there is at least one metal layer, forming a radiant barrier to reduce heat loss via radiation, and insulating this metal layer from conductive heat loss, and a process for its manufacture.
Claims42
An infra-red reflective composite comprising:
- an outer layer comprising a foam material;
- an inner layer comprising a fleece material;
- a closed cell neoprene foam layer sandwiched between the outer layer and the inner layer, and
- at least one metal layer facing the closed cell foam layer, comprising a material selected from the group consisting of Al, Cu, Au, Zn, Mg, Ti, Ag, AL2O3, stainless steel, AgGe, CuZn, CuSn, CuAg, or CuAgSn;
- wherein the closed cell foam layer comprises a pattern of perforations through the closed cell foam layer, which create gaps that expose at least a portion of the metal layer;
- and
- wherein said perforations expose over 30% of a surface area of the metal layer.

An infra-red reflective composite comprising:
- an outer layer comprising a fabric material;
- a membrane layer adjacent to an inside surface of the outer layer;
- a metal layer adhered to an inside surface of the membrane layer, comprising a material selected from the proud consisting of Al, Cu, Au, Zn, Mg, Ti, Ag, AL2O3, stainless steel, AgGe, CuZn, CuSn, CuAg, or CuAgSn;
- an inner layer comprising a fleece material;
- and
- a closed cell neoprene foam layer sandwiched between the metal layer and the inner layer, and
- wherein the closed cell foam layer comprises a pattern of perforations through said closed cell foam layer, which create gaps that expose at least a portion of the metal layer;
- wherein said membrane layer is substantially water vapor permeable;
- and
- wherein said perforations expose over 30% of a surface area of the metal layer.
