Abstract
Electric resistance heating/warming composite fabric articles have a fabric layer having a first surface and an opposite, second surface, and an electric resistance heating/warming element in the form of a conductive yarn mounted upon first surface of the fabric layer, e.g. in embroidery stitching, and adapted to generate heating/warming when connected to a power source. A barrier layer may be positioned, for example, at least adjacent to the first or second surface of the fabric layer. Methods of forming electric resistance heating/warming composite fabric articles are also described.

A method of forming an electric resistance heating/warming composite fabric article, comprising:
- providing a fabric layer having a first surface of raised fibers of electrically-insulating material and an opposite, second surface,
- mounting an electricity conductive yarn among, the raised fibers of the first surface of the fabric layer in a manner to cause the raised fibers to electrically isolate adjacent segments of the electrically conductive yarn disposed in a predetermined pattern of an electric circuit to form an electric resistance heating/warming element adapted for connection to a power source, thereby to generate heating/warming,
- connecting adjacent segments of the electrically conductive yarn in the electrical circuit in parallel, with a first segment of the conductive yarn having a first resistance and a second segment of the conductive yarn having a second resistance, the first resistance being different from the second resistance, and
- positioning a barrier layer resistant to passage of air and water droplets and permeable to passage of water vapor at least adjacent to at least one of the first surface of the fabric layer and the opposite, second surface of the fabric layer.
