Heating articles using conductive webs
View Patent ↗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.
1. A heating article comprising:
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.
2. The heating article of claim 1 , wherein at least a portion of the nonconductive region is formed by bonding.
3. The heating article of claim 1 , wherein the first layer is absorbent.
4. The heating article of claim 1 , wherein the nonwoven fibers include polymeric fibers.
5. The heating article of claim 1 , wherein the heating element is disposable.
6. The heating article of claim 1 , wherein the power source is rechargeable.
7. The heating article of claim 1 , wherein the power source is durable.
8. The heating article of claim 1 , wherein the power source is labeled for properly-oriented coupling to the first layer.
9. The heating article of claim 1 , wherein the power source is coupled to the first layer with conductive hook material.
10. The heating article of claim 1 , the heating element further comprising a second layer superposed with the first layer, wherein the second layer includes nonwoven fibers mixed with non-metallic conductive fibers, wherein the second layer is divided to include a conductive region and a nonconductive region.
11. The heating article of claim 10 , wherein the first and second layers are separated by an insulating layer.
12. The heating article of claim 11 , wherein the insulating layer is electrically insulating.
13. The heating article of claim 11 , wherein the insulating layer is thermally insulating.
14. The heating article of claim 1 , the heating element further comprising a water-resistant layer superposed with the first layer.
15. The heating article of claim 1 , the heating element further comprising an absorbent layer superposed with the first layer.
16. The heating article of claim 1 , the heating element further comprising a protective layer superposed with the first layer.
17. The heating article of claim 1 , the heating element further comprising a heat-reflective layer superposed with the first layer.
18. The heating article of claim 1 , further comprising a scent substance adapted to release a scent when heated.
19. The heating article of claim 1 , wherein the conductive fibers are non-metallic.
20. A heating article comprising:
a heating element including
a first layer of nonwoven fibers mixed with non-metallic 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 second layer superposed with the first layer, wherein the second layer is substantially free of non-metallic conductive fibers; and
a power source removably coupled to the first and second ends.
