Abstract: A woven fibrous article that generates heat upon application of electrical power has a woven fibrous body consisting of a set of non-conductive warp yarns and a set of non-conductive filling or weft yarns. One of the set of non-conductive warp yarns and the set of non-conductive filling or weft yarns, in one or more first regions, consists of relatively more coarse yarns and in one or more second regions consists of relatively more fine yarns with electrical conductor elements extending generally along the second regions of the woven fibrous body to connect the plurality of spaced apart electrical conductance heating elements in a parallel electrical circuit to a source of electrical power.
