Background technique

Down jackets are the most effective clothing to help the wearer stay warm in extremely cold environments. However, it also has its limitations. The cost of high-quality down jackets is relatively high. The cumbersome nature of down jackets makes them unsuitable for occasions where the wearer's flexibility cannot be compromised. In addition, when the weather is so cold that warmth alone cannot keep the wearer warm and comfortable, an external heat source is required.

External heat sources usually involve resistive heating, a method in which electricity is generated by passing electricity through an electrical conductor with a considerable resistance. In the products sold on the market, the heating element inside is usually metal wire, metal mesh or carbon fiber. However, such materials have their disadvantages. A thick wire or mesh is not flexible enough, and a thin, thin wire or mesh is too fragile and breaks too easily. Carbon fiber is relatively expensive to produce and has poor heating properties.

This proposal presents a solution how to make a soft and flexible heating element and a design surrounding the heating element. The heating elements mentioned in this proposal have good flexibility due to their thinness. And its metal construction makes it also has good heating performance. Due to the low amount of raw materials required, the production costs of this heating element are also relatively low. The invention also encompasses a design that allows the thermal energy generated from the fabric to be evenly distributed across the surface of the textile construct. It has the potential to become a mainstream solution for the production of heatable fabric garments.

Patent application number: 2012105631330 discloses a fabric and its intelligent heating method. The present invention discloses a fabric and its intelligent heating method. The fabric includes an inner surface and an outer surface. The method includes: connecting the circuit diagram On the inner surface, the circuit diagram is connected with a sheet-shaped conductive layer that generates heat with electricity; the conductive layer has a set resistance in the set area of the cloth fabric, so that when the circuit diagram conducts current , the cloth fabric produces local heating. However, the application mentions that the conductive layer is made of metallized sheet materials, metallized fabrics, metallized sheets and metal foils in specific embodiments, and can be die-cut into required circuit patterns. Conventionally, the conductive layer is made of metallized sheets Generally, it is easy to increase the weight of the fabric if it is made of shape material.

Patent application number: 201510290673X discloses an electric blanket, and the invention relates to an electric blanket. An electric blanket, comprising: a heating film including a first insulating layer; a conductive layer formed on the surface of the first insulating layer; an electrode layer formed on the surface of the conductive layer and electrically connected to the conductive layer, The electrode layer includes a positive electrode and a negative electrode. The positive electrode includes a positive bus bar and a plurality of positive internal electrodes extending from the positive bus bar. The negative electrode includes a negative bus bar and a plurality of positive inner electrodes extending from the negative bus bar. A plurality of negative internal electrodes extending from the strip, the positive internal electrodes and the negative internal electrodes are alternately arranged and spaced apart from each other; and a second insulating layer is formed on the surface of the electrode layer; a protective cover, the heating film accommodated in the protective cover; and connecting wires electrically connected to the electrode layer of the heating film. The above-mentioned electric blanket can be powered by a lower voltage.

It is mentioned in the description of the application that the material of the electrode layer is silver, copper, aluminum, platinum, graphene, carbon nanotubes, ITO, FTO or AZO. Of course, the electrode layer can also be formed by coating silver paste or copper paste and curing. However, it is difficult to fix the copper paste well by applying the silver paste or copper paste on the first insulating layer. Once it is worn on clothes, it will cause the silver paste or copper paste to break due to wrinkles or during cleaning.
