Abstract
An electric heating device includes: a conductive fabric including a plurality of thread sets and a plurality of parallel first insulator threads, each of the thread sets including a plurality of parallel conductive threads interlaced with the first insulator threads; and a heat-generating material covering the conductive fabric. The heat-generating material has a resistivity greater than a resistivity of the conductive threads.
Claims20
An electric heating device comprising:
- a conductive fabric including a plurality of thread sets, and a plurality of parallel first insulator threads extending in a first direction, each of said thread sets including a plurality of parallel conductive threads extending in a second direction transverse to the first direction and interlaced with said first insulator threads;
- and
- a heat-generating material covering said conductive fabric, in contact with said conductive threads of said thread sets of said conductive fabric, and capable of generating heat when a current is applied thereto through said conductive threads;
- wherein said heat-generating material has a resistivity greater than a resistivity of said conductive threads.
