Abstract
Fabrics made for 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 from the human body, and insulating this metal layer from heat loss via conduction, and a process for its manufacture.
Claims17
An infra-red reflective composite, comprising:
- a first moisture vapour permeable substrate having a bottom surface;
- a first metal layer disposed on the bottom surface of the first moisture vapour permeable substrate;
- a second moisture vapour permeable substrate having a top surface;
- a second metal layer disposed on the top surface of the second moisture vapour permeable substrate;
- an insulating textile layer disposed between the first metal layer and the second metal layer such that a top surface of the insulating textile layer is adjacent to the first metal layer and a bottom surface of the insulating textile layer is adjacent to the second metal layer, wherein the insulating textile layer covers substantially all of the first metal layer and the second metal layer;
- and
- wherein said insulating textile layer has a substantially lower thermal conductivity than the first metal layer, and has a structure which comprises gaps at the top surface and bottom surface of the insulation textile layer which exposes a portion of the first metal layer for infra red reflection while also providing mechanical separation of the first metal layer from the second metal layer, and wherein the insulating textile layer comprises a non-woven structure formed with fibers.
