Abstract
Electric heating/warming composite fabric articles have at least a fabric layer having inner and outer surfaces, and an electric heating/warming element in the form of a flexible, preferably stretchable, electricity-conducting film disposed at the inner surface of the fabric layer and adapted to generate heating/warming when connected to a power source. A barrier layer may be positioned, for example, adjacent to the inner surface of the fabric layer; e.g., with the electric heating/warming element formed thereupon. Methods of forming electric heating/warming composite fabric articles are also described.
