Fabrics made for apparel, tents, sleeping bags and the like, in various composites, constructed such that a combination of substrate layers and insulation layers is configured to provide improved thermal insulation. The fabric composites are constructed to form a radiant barrier against heat loss via radiation and via conduction from a body.

This invention provides a new class of medical devices and implants comprising amorphous metal alloys. The medical devices and implants may be temporary or permanent and may comprise other materials as well, such as polymers, ceramics, and conventional crystalline or polycrystalline metal alloys. Specifically, this invention provides implantable surgical fabrics comprising amorphous metal alloys. The presence of amorphous metal alloys in these fabrics can serve a variety of purposes, including structurally reinforcing the surgical fabric and/or imparting to the fabric the ability to shield against harmful radiation. The fabric may be used inside or outside the body during medical procedures. Further, the implantable surgical fabrics may be woven or non-woven fabrics.

A fabric having resilient prominences on at least one surface is described for improved thermal protection, drag reduction and quick drying. Resilient prominences are bulges that extend outward from a fabric surface and trap some volume of air or other material therein. For example, a resilient prominence may be dome shaped and extend outward from the fabric plane. A resilient prominence is resilient in shape, whereby the resilient prominence may be compressed and then popped back into substantially the original shape. Reflective and/or absorptive materials may be configured on the surface of the fabric to provide camouflage from IR cameras. Reflective material may be configured on the fabric to reflect heat back to the wearer of a garment made with the fabric described.
