A METHOD OF PREPARING A PIECED HEAT-RADIATING SHEET USING CARBON HEAT-RADIATING FIBER

摘要

The present invention relates to a method for manufacturing a pieced planar heating sheet using carbon heating yarns and, more particularly, to a method for manufacturing a pieced planar heating sheet cut into a vehicle seat shape or a shape, such as a chair and a sofa, using carbon heating yarns, which can improve waterproof and dampproof properties to prevent the possibility of a short circuit even when a user spills water on the product or an external humidity is high, can improve antifouling properties to prevent the inside from being polluted or heating performance from being deteriorated by the intrusion of a foreign substance, can have no need to open the coated surface of the product in order to connect a power cable to a temperature sensor to simplify the work and improve marketability, and can prevent the possibility of a short circuit and separation of the temperature sensor due to damage to a soldered portion, and to enable workers to freely carry the pieced planar heating sheet, thereby significantly improving workability.
