▎ 摘　　要

NOVELTY - Heating cloth comprises silver fiber fabric layer (6), graphene polyester fabric layer (7) and wire (8). Two wires are arranged between graphene polyester fabric layer and silver fiber fabric layer for connecting with positive and negative poles of external power supply. The wires are arranged on left and right sides of silver fiber fabric layer and graphene polyester fabric layer. The wire, silver fiber fabric layer and graphene polyester fabric layer are welded together. The graphene polyester fabric layer comprises 10-20 pts. wt. graphene and 80-90 pts. wt. polyester. The specification of fiber in graphene polyester fabric layer is 70-80D. The silver fiber fabric layer comprises 15-25 wt.% silver fiber. The resistance value of silver fiber fabric layer is 0.5-1.5 Ω /m2. The weight of graphene polyester fabric layer is 100-150 g/m2. The weight of silver fiber fabric layer is 150-200 g/m2. USE - The heating cloth is used for far-infrared underwear based on graphene (claimed). DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view showing the A-A structure of a heating cloth for far infrared underwear based on graphene. 6Silver fiber fabric layer 7Graphene polyester fabric layer 8Wire
