ABSTRACT:
An electrically conductive non-woven web for a heating element is formed from a non-woven sheet comprising conductive fibers which is saturated with a dispersion comprising conductive particles. Embodiments adapted for use at low voltages and at household voltages are provided. In a preferred, flame-resistant embodiment, the heating element is a sandwich containing, from bottom to top, a first insulating non-woven sheet comprising polyaramid fibers, an electrically conductive web comprising carbon fibers, polyaramid fibers, and carbon black. A pair of conductive strip attached in electrical contact to the web, and a second insulating non-woven sheet comprising polyaramid fibers.
