Fabrics made for apparel, tents, sleeping bags and the like, in various composites, constructed such that it provides improved thermal insulation and a barrier against heat loss via IR radiation. All composites comprise a substrate, a metal layer and an insulation layer. One composite comprises a moisture vapour permeable substrate, a first insulation layer adjacent to the first surface of the substrate, and a second insulation layer adjacent to the second surface of the substrate. Another composite comprises a moisture vapour permeable substrate 110, a metal layer 120 adjacent to the first surface of the substrate, a first insulation layer 130 adjacent to the metal layer, and a second insulation layer 230 adjacent to the second surface of the substrate. A third composite comprises a moisture vapour permeable and liquid impermeable substrate, an insulation layer, and a metal layer. Further substrate layers 140, 240 may be added to the composite. The substrate may be a (stretch) woven, non-woven or knitted textile, e.g. of nylon, polyester, polypropylene, cotton or wool. The insulating layers may be polyester fibres, feathers or downs. |
