[0002] Electric heating fabric is a heating device used on the bed. It is mainly used when it is cold to reach the required bed temperature when people are sleeping. It has the characteristics of low power consumption, adjustable temperature, easy use and wide application, and has a history of nearly 100 years. The basic principle of traditional electric heating fabric is to arrange flexible electric heating wires with qualified insulation performance in a flexible blanket.

[0025] Reference Figure 1 The utility model provides an electric heating fabric, including an outer fabric layer 110, a lining fabric layer 210 and a heating layer 410, wherein the heating layer 410 is a flexible heating material, arranged inside the lining fabric layer 210, and the outer fabric layer 110 is arranged on the upper and lower surfaces of the lining fabric layer 210; wherein the lining fabric layer 210 and the outer fabric layer 110 are bonded by glue powder 1101.

[0026] Reference Figure 2 The electric heating fabric provided in the embodiment of the present application is sequentially stacked with an outer fabric layer 110, a lining fabric layer 210, a heating layer 410, a lining fabric layer 210, and an outer fabric layer 110 from top to bottom.

[0027] The outer fabric layer 110 is the user contact surface, and the outer fabric layer 110 is made of flexible materials, such as cloth, plastic film, etc., so that the user feels skin-friendly and soft. The lining layer 210 can play a good role in heat insulation. The heating layer 410 also uses flexible heating materials, such as carbon nanofilm, carbon fiber, graphene, silver paste, fullerene, etc., which makes the softness and comfort of the entire blanket even higher.

[0028] The electric heating fabric also includes glue powder 1101, which is compounded on the outer fabric layer 110 and used to bond the outer fabric layer 110 and the lining fabric layer 210. The glue powder 1101 is selected from powder glue powders such as polyacrylamide glue powder 1101 (PA glue powder), polymer environmentally friendly hot melt adhesive (PES glue powder), and hot melt glue powder. When used to bond the outer fabric layer 110 and the lining fabric layer 210, the electric heating fabric is made softer and the weight of the entire blanket can be significantly reduced. In some embodiments, the thickness of the electric heating fabric can be less than 2 mm, which is very light and feels similar to an ordinary blanket without a heating function.

[0029] A further improvement of the utility model is that a flexible circuit electrode 4101 is provided on the heating layer 410, and the flexible circuit electrode 4101 includes but is not limited to a flexible printed circuit (FPC), a flexible copper clad laminate (FCCL) and copper foil. The flexible circuit electrode 4101 is light in weight, thin in thickness, and can be bent and folded freely, making the electric heating fabric softer and thinner.

[0030] As an optional method, the upper and lower surfaces of the heating layer 410 of the electric heating fabric are bonded to the lining cloth layer 210 through a thermoplastic polyurethane film (Thermoplastic Polyurethane, TPU film).

[0031] A further improvement of the present invention is that the lining cloth layer 210 is hollowed out to form holes 2101, so that the overall weight of the lining cloth can be reduced, which has a significant effect on reducing the overall weight of the electric heating fabric.

[0032] As an alternative, Figure 3 As shown, the holes 2101 on the lining cloth layer 210 are distributed in an array, and the ordered and compact holes 2101 can balance the requirements of lightweight and heat preservation of the electric heating fabric.

[0033] As an optional method, the lining cloth layer 210 on one side of the heating layer 410 is provided with holes 2101, so that the lining cloth layer 210 on the side of the electric heating fabric close to the user's body has holes 2101, and the other side has no holes 2101 or has far fewer holes 2101 than the lining cloth layer 210 on the side close to the user's body. In this way, the lining cloth layer 210 on the side close to the user's body can transfer the heat of the heating layer 410 faster for the user to keep warm, while the other side can prevent heat loss well and is more warm.

[0034] As an alternative, refer to Figure 4The outer fabric layer 110 includes a first outer fabric layer 1102 and a second outer fabric layer 1103 which are arranged on both sides of the lining cloth layer 210, and the thickness of the first outer fabric layer 1102 is less than that of the second outer fabric layer 1103. The first outer fabric layer 1102 is used as the side close to the user's body, and the thicker second outer fabric layer 1103 is the contact surface with the environment. The first outer fabric layer 1102 transfers the heat of the heating layer 410 more quickly for the user to keep warm, and the second outer fabric layer 1103 effectively prevents the heat exchange between the electric heating fabric and the environment, and can take into account both the warmth retention and lightness of the electric heating fabric.

[0035] As an optional method, after the layers of the electric heating fabric are stacked, an overall hot pressing packaging process is adopted to manufacture the fabric.

[0036] As an optional method, the electric blanket provided in the embodiment of the present application can be an electric blanket, or cloth, clothing, etc.

[0037] After adopting the above technical scheme, the beneficial effects of the utility model are as follows: compared with ordinary electric heating fabrics, the electric heating fabric of the utility model adopts glue powder 1101 to bond the outer fabric layer 110 and the lining fabric layer 210, and each layer is made of flexible material, and a flexible heating layer 410 is selected, which is lighter, softer, more comfortable, and more resistant to bending, and the feel is very close to that of ordinary blankets without heating, so it can meet the diversified needs of users such as spreading, draping, and covering.

[0038] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
