Abstract
Methods of forming an electric heating/warming composite fabric article include the steps of applying an electricity-conducting paste upon a surface in a predetermined pattern of an electric circuit, and curing the electricity-conducting paste to form an electric heating/warming element in the form of a flexible, electricity-conducting film defining an electric circuit, the electric heating/warming element being adapted for connection to a power source, thereby to generate heating/warming. The fabric article includes a fabric layer, and may include a barrier layer joined to or associated with a surface of the fabric layer. The electric circuit may be formed directly upon a surface of the fabric layer or upon a surface of the barrier layer. The circuit may be formed and cured upon the barrier layer before or after it is joined to the fabric layer.
