Abstract
The utility model provides a composite fiber electric heating twisted wire. The composite fiber electric heating twisted wire is characterized in that a plurality of ultrafine strands of composite metal fiber threads with a diameter of 8-20 microns are twisted to form the heating twisted wire. The composite fiber electric heating twisted wire has high strength and favorable flexibility which can not only guarantee safe electricity usage, and are very important for electric blankets and electric clothes produced by manufacturers, because the electric blankets and electric clothes are always needed to be folded, put in/off and washed. In the same circumstance, a traditional metal heating wire can be broken and causes short circuit easily. In short, the ultrafine composite fiber electric heating twisted wire can be positioned at a place which is extremely adjacent to a heated surface, and therefore, heating speed can be improved, and energy consumption can be reduced.
