Abstract
A thermal fiber sleeping bag structure comprises a sleeping bag body and a thermal fiber mat which is laid on the sleeping bag body. The thermal fiber mat is woven by scalable, flexible yarns which can be heated when energized with power, and which includes non-conductive main axis threads and a conductive fine metal filament spirally wound around the outside of the main axis threads. According to this structure of laying the thermal fiber mat on the sleeping bag body, a thermal fiber sleeping bag capable of generating heat upon energizing with electric power can be obtained for indoor or outdoor heating in winter season.
