Self-heating fabric

A fabric body comprises a graphene layer arranged inside the fabric body, a heat transfer layer of which the upper surface is bonded and connected to the lower surface of the graphene layer and is used for transferring heat from the graphene layer, and a contact layer of which the upper surface is bonded to the lower surface of the heat transfer layer and is used for transferring heat from the graphene layer, and a heat transfer layer for transferring heat from the heat transfer layer to the skin surface. According to the fabric, the graphene layer is arranged in the fabric body, when the fabric body is worn, the graphene layer and the human body resonate through far infrared rays to achieve heat energy circulation, the human body is made to generate heat, and the warm keeping effect is lasting; after the graphene layer emits heat, heat is transferred to the skin surface through the heat transfer layer and the contact layer, and when the fabric is used in an extremely cold environment or severe weather, the f
