▎ 摘　　要

NOVELTY - Heating source comprises a vinyl fabric, an outer sheet having double-layer structure of an inland (10) and a appendage (20), and mesh fibers (30) formed sandwiched between the inland and appendage, where the mesh fiber is formed by impregnating graphene powder and coating the surface with a thermally conductive coating liquid. USE - The heating source is useful for vinyl house containing graphene (claimed). ADVANTAGE - The heating source has improved thermal insulation and durability properties, and improves thermal efficiency by utilizing small electricity quantity. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for producing (a) preparing the exothermic vinyl fabric, the outer sheet and the mesh fiber, and (b) placing the appendage bottom of the mesh fiber, laminating the exothermic vinyl fabric, and bonding together by high frequency welding using a high frequency welding machine. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic representation of the heating source. Inland (10) Appendage (20) Mesh fibers (30)
