Description

technical field [0001] The invention relates to a graphene heating fabric and a production method and system thereof. Background technique [0002] The winter in the north is extremely cold. In the cold winter, people often need a series of heating products, especially when they are outdoors, they need heating equipment that can be carried with them. The heating products sold on the market are generally double-layer insulation The electric heating element is sandwiched between the cloth, and the purpose of heating is achieved through the electric heating element. The electric heating elements in traditional acoustic heating equipment often use metal resistance wires to generate heat. However, the heating area of ​​metal resistance wires is small and cannot perform all-round heating activities on the body. There is also a heating device that uses conductive fibers to weave into conductive fabrics, and puts the conductive fabrics into the clothes. Because the conductive fabri...
