For example, A and / or B can represent three situations: A exists alone, A and B exist at the same time, and B exists alone.

It is only for the convenience of describing the embodiments of the present application and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it cannot be understood as a limitation on the embodiments of the present application.

[0027] 1 , the present application provides an electric heating fabric, comprising 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 and is arranged inside the lining fabric layer 210 , and the outer fabric layer 110 is provided on both 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 together by glue powder 1101 .

[0028] 2 , the electric heating fabric provided in the embodiment of the present application includes 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 stacked in sequence from top to bottom.

[0029] The outer fabric layer 110 is the user contact surface and is made of flexible materials such as cloth, plastic, and film, providing a soft, skin-friendly feel. The lining layer 210 provides excellent thermal insulation. The heating layer 410 is also made of flexible heating materials such as carbon nanofilm, carbon fiber, graphene, silver paste, and fullerene, further enhancing the softness and comfort of the blanket.

[0030] The electric heating fabric also includes adhesive powder 1101, which is compounded onto the outer fabric layer 110 and used to bond the outer fabric layer 110 to the lining fabric layer 210. The adhesive powder 1101 can be made from a powdered adhesive such as polyacrylamide adhesive powder 1101 (PA adhesive powder), a high-molecular-weight environmentally friendly hot-melt adhesive (PES adhesive powder), or a hot-melt adhesive. When used to bond the outer fabric layer 110 to the lining fabric layer 210, the electric heating fabric becomes more flexible while significantly reducing the weight of the blanket. In some embodiments, the thickness of the electric heating fabric can be less than 2 mm, making it very lightweight and similar in feel to a conventional blanket without heating function.

[0031] The adhesive powder 1101 may be a flexible adhesive material, including but not limited to PA adhesive powder, PSE adhesive powder, and hot melt adhesive powder. The adhesive powder 1101 may also be an adhesive film, mesh adhesive, or other adhesive material.

[0032] The lining layer 210 can be a packaging material, including but not limited to gauze, non-woven fabric, etc. The lining layer 210 can also be a material such as a film or a mesh adhesive, wherein the film can be a TPU film.

[0033] In this application, a flexible circuit electrode 4101 is provided on the heating layer 410. 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 lightweight, thin, and can be bent and folded freely, making the electric heating fabric even softer and thinner.

[0034] The upper and lower surfaces of the heating layer 410 of the electric heating fabric are bonded to the lining fabric layer 210 via a thermoplastic polyurethane (TPU) adhesive film 310 .

[0035] In the present application, the lining cloth layer 210 is hollowed out to form holes 2101, so that the overall weight of the lining cloth is reduced, which has a significant effect on reducing the overall weight of the electric heating fabric.

[0036] As shown in FIG3 , the holes 2101 on the lining cloth layer 210 are distributed in an array. The ordered and compact holes 2101 can strike a good balance between the requirements of lightweight and heat preservation of the electric heating fabric.

[0037] 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 to keep the user warm, while the other side can effectively prevent heat loss and is more warm.

[0038] 4 , the outer fabric layer 110 includes a first outer fabric layer 1102 and a second outer fabric layer 1103 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 regarded 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 faster to provide heating for the user, and the second outer fabric layer 1103 effectively prevents 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.

[0039] After the multiple layers of the electric heating fabric are stacked, the whole is made by hot pressing and packaging.

[0040] The electric blanket provided in the embodiment of the present application can be an electric blanket, or cloth, clothing, etc.

[0041] Compared with ordinary electric heating fabrics, the electric heating fabric of the present application uses glue powder 1101 to bond the outer fabric layer 110 and the lining fabric layer 210. Flexible materials are used for multiple layers, and a flexible heating layer 410 is used. It is lighter, softer, more comfortable, and more resistant to bending. The feel is very similar to that of an ordinary non-heated blanket, so it can meet the user's diverse needs for spreading, draping, and covering.
