The existing electric heating cloth is mainly carbon fiber electric heating cloth and is formed by weaving flame-retardant fibers and carbon fibers. Since the carbon fiber itself has a low resistance, it is necessary to consider the relationship between the amount of heat generation and the resistance when designing a product (the lower the resistance at the same voltage, the higher the temperature). Specifically, only part of the weft yarns are carbon fibers, most of the weft yarns are flame-retardant fibers, and the carbon fibers and the flame-retardant fibers are respectively woven with warp yarns of the flame-retardant fibers to form the electric heating cloth. Fig. 2 is a schematic view of the conventional carbon fiber electric heating cloth, which shows only a number of carbon fiber weft yarns 1' spaced apart from each other, and none of the other flame retardant fiber warp yarns and flame retardant fiber weft yarns are shown. Obviously, the conventional carbon fiber electric heating cloth is linear heating, and the temperature of the carbon fiber weft yarn 1 'in the heating process is much higher than that of other parts, namely the temperature around the black line of the carbon fiber weft yarn 1' is higher than that of other parts, so that the heating is uneven.

In addition, the existing electric heating cloth only comprises groups of electrodes, so that only electric powers can be provided for heating.

The heating area A of the graphene composite electric heating cloth is formed by weaving flame-retardant fibers and graphene heating wires (also called graphene fibers), since the resistance of the graphene heating wires is high, all weft yarns of the heating area A are the graphene heating wires, in the embodiment, the graphene heating wires are graphene aramid fibers provided by CN201810890616.9, it is understood that the graphene heating wires can also be other graphene fibers formed by attaching graphene to the fibers, in addition, warp yarns of the heating area A are flame-retardant fibers and conductive wires, which are respectively woven with the graphene heating wire weft yarns to form the heating area A. in FIG. 1 of the embodiment, only four

conductive wires

11, 12, 13, 14 which are separated from each other are shown, and other warp yarns and other weft yarns of the flame-retardant fibers are not shown with lines, wherein, the third conductive wire 11 and the second conductive wire 12 can form a third group of electrodes, the second conductive wire 12 and the third conductive wire 13 can form a second group of electrodes, the third conductive wire 11 and the third conductive wire 13 can form a third group of electrodes, the fourth conductive wire 11 and the fourth conductive wire 14 can form a third group of electrodes, the fourth conductive wire 12 and the fourth group of electrodes, the fourth conductive wire 14 can form a third group of electrodes, and the fourth group of electrodes can form a fourth group of electrodes by connecting method, and the fourth group of the fourth conductive wire 14, and the fourth group of the third conductive wires, which are formed by connecting the fourth conductive wires, and the fourth group of the third conductive wires, and the third group of the fourth.
