Abstract
Abstract Weavable yarns whose fibers are metallic or have a heat conducting, metallized coating are woven together with a plurality of yarn layers using, say, an angle weave to produce an interlocked, multilayer fabric. The fabric provides heat conduction paths for the efficient transferring of heat from a substrate. Typical coated or metallic fibers which may be employed in the yarn include glass, graphite, ceramic, polyester, nylon, rayon, cotton, wool, acrylonitrile, etc.; metallic fibers such as copper, aluminum and steel are also suitable. A preferred heat conductive coating comprises an aluminum, aluminum alloy or other suitable metal which can be applied to a glass fiber.
