Heating articles using conductive webs

摘要

A heating article is provided including a heating element including a first layer of nonwoven fibers mixed with conductive fibers, wherein the layer is divided to include a conductive region and a nonconductive region, wherein the conductive region extends in a co-extensive and co-planar pattern in a majority of the layer, and wherein the conductive region has first and second ends, and a power source removably coupled to the first and second ends. The first layer can include nonwoven fibers mixed with non-metallic conductive fibers. The heating article can also include a second layer superposed with the first layer, wherein the second layer is substantially free of non-metallic conductive fibers.
