Abstract
Electroconductive paper structure with cellulosic fibrous materials and electroconductive fibers, wherein the electroconductive paper structure has embedded therein a continuous, electroconductive thread for contacting the electroconductive paper structure from one end to the opposite end of the paper structure.
Claims16
An electroconductive paper structure, comprising:
- at least one electroconductive paper ply with cellulosic fibrous materials and electroconductive fibers, and
- a plurality of continuous, electroconductive threads embedded in and surrounded on at least three sides by the electroconductive paper ply for contacting the electroconductive paper structure from one end to the opposite end of the paper structure to provide a current to the electroconductive paper ply;
- wherein the electroconductive paper structure is a heating element.
