Description

Technical Field

[0001] This utility model relates to the field of footwear manufacturing technology, specifically to a nano-closed-cell flyknit thermal insulated shoe upper. Background Technology

[0002] Most flyknit uppers on the market are made using conventional textile materials and weaving techniques. Their warmth relies primarily on the thickness of the material itself and some simple added insulating coatings. For example, some flyknit uppers are woven from ordinary polyester fibers, then a thin layer of insulating rubber is applied to the surface to try and block cold air from entering. The weaving structure is usually an open mesh structure, which ensures breathability but is not very effective at retaining heat. Moreover, in cold environments, this conventional upper construction is unlikely to effectively prevent cold air from continuously penetrating from the outside, making the feet feel cold and failing to provide the wearer with a good and lasting warm experience.

[0003] The existing shoe uppers have the following shortcomings:

[0004] 1. Insufficient warmth retention: Existing flyknit uppers rely on simple material thickness and ordinary insulating coatings for warmth, lacking more effective internal structural design. In low-temperature environments, heat is easily lost through the open mesh structure of the upper, failing to effectively lock in the heat generated by the feet, making it difficult to meet the need for foot warmth during long-term outdoor activities in cold weather.

[0005] 2. Poor heat insulation: The open mesh structure and conventional upper construction allow cold air from the outside to easily penetrate the upper and enter the shoe, failing to form an effective heat insulation barrier. As a result, even in a not very cold environment, the wearer may feel cold feet due to the continuous infiltration of cold air.

[0006] 3. Poor heat retention: Since the problem of heat retention inside the shoe upper material and insulation from external cold air has not been fundamentally solved, the heat retention effect of the existing flyknit upper will decrease rapidly with the increase of wearing time and changes in the external temperature, and it cannot continuously create a warm and comfortable environment for the feet. Utility Model Content

[0007] The purpose of this invention is to solve the problems of insufficient warmth, heat insulation, and heat preservation durability of existing shoe uppers, as well as insufficient comfort.

[0008] To achieve the above objectives, the present invention adopts the following technical solution:

[0009] A nano-closed-cell flyknit thermal insulated shoe upper, characterized in that: it includes an upper base layer, a first upper effect layer and a second upper effect layer disposed on the upper surface of the upper base layer, wherein the upper base layer, the first upper effect layer and the second upper effect layer are all made of flyknitted yarn mixed with fiber and nano-closed-cell material, and the upper base layer is provided with a plurality of breathable parts, wherein breathable sports fabric is disposed in the breathable parts.

[0010] A further improvement is that the first upper effect layer is a slightly raised effect layer or a double-layer effect layer.

[0011] A further improvement is that the second upper effect layer is a double-layer micro-convex effect layer.

[0012] A further improvement is that the first and second upper effect layers are made of yarns made of a mixture of bulky yarn and nano-closed-cell materials.

[0013] A further improvement is that the upper base layer is made of yarn woven from a mixture of spandex and nano-closed-cell materials.

[0014] A further improvement is that the plurality of the air-permeable parts include a first air-permeable part, a second air-permeable part, a third air-permeable part, and a fourth air-permeable part, wherein the first air-permeable part and the third air-permeable part are composed of a plurality of microporous air-permeable holes, and the second air-permeable part and the fourth air-permeable part are composed of a plurality of elongated air-permeable holes.

[0015] A further improvement is that the colors of the shoe upper base layer, the first shoe upper effect layer, and the second shoe upper effect layer are the same.

[0016] A further improvement is that the breathable sports fabric is a different color from the base layer of the shoe upper, the first shoe upper effect layer, and the second shoe upper effect layer.

[0017] Compared with existing technologies, the above technical solution has the following advantages:

[0018] The upper is made of yarn woven from nano-closed-cell material. The nano-closed cells can effectively limit the heat transfer path, making it difficult for the heat generated by the feet to be lost through conduction and convection. It is like building a series of "heat barrier walls" inside the upper, which greatly improves the heat insulation performance of the upper and solves the problem of heat loss and insufficient warmth of existing uppers.

[0019] The nano-closed-pore structure also plays a good role in blocking cold air from the outside. It is difficult for cold air to penetrate these dense and tiny closed pores to enter the shoe, just like putting an "invisible warm protective suit" on the shoe surface. It effectively improves the shortcomings of existing shoe surfaces, such as poor heat insulation and easy penetration of cold air from the outside, creating a relatively warm and stable internal environment for the feet and enhancing the durability of heat preservation.

[0020] The breathable sports fabric in the breathable part, combined with the nano-closed-cell structure, is not completely sealed. Instead, at the microscopic level, it can ensure heat and cold air blocking while allowing a suitable amount of air exchange, keeping the feet dry and avoiding stuffiness. Furthermore, the soft and foot-fitting characteristics of the flyknit technology itself are still retained, so the wearer can enjoy the warmth without feeling foot discomfort, thus improving overall comfort.

[0021] As mentioned before, the application of nano-closed-cell technology to flyknit shoe uppers can start from the internal structure of the upper, using the nano-level closed-cell structure to form a stable insulation layer, thereby improving the insulation performance of the upper, enhancing the durability of insulation, and improving overall comfort.

[0025] See Figure 1 As shown, the technical solution adopted in this specific embodiment is: a nano-closed-cell flyknit thermal insulated shoe upper, including a shoe upper base layer 1, a first shoe upper effect layer 2 and a second shoe upper effect layer 7 disposed on the upper surface of the shoe upper base layer 1, wherein the shoe upper base layer 1, the first shoe upper effect layer 2 and the second shoe upper effect layer 7 are all flyknitted from yarns mixed with fibers and nano-closed-cell materials, and a plurality of breathable parts are provided on the shoe upper base layer 1, wherein a breathable sports fabric is disposed in the breathable parts.

[0026] The first shoe upper effect layer 2 is a micro-convex effect layer or a dual-layer effect layer.

[0027] The second upper effect layer 7 is a double-layer micro-convex effect layer.

[0028] The first upper effect layer 2 and the second upper effect layer 7 are made of yarns made of a mixture of bulky yarn and nano-closed-cell material.

[0029] The shoe upper base layer 1 is made of yarn made of a mixture of spandex and nano-closed-cell materials.

[0030] The plurality of breathable parts include a first breathable part 3, a second breathable part 4, a third breathable part 5, and a fourth breathable part 6. The first breathable part 3 and the third breathable part 5 are composed of a plurality of microporous breathable holes, and the second breathable part 4 and the fourth breathable part 6 are composed of a plurality of elongated breathable holes.

[0031] The shoe upper base layer 1, the first shoe upper effect layer 2, and the second shoe upper effect layer 7 are all the same color.

[0032] The breathable sports fabric is different in color from the shoe upper base layer 1, the first shoe upper effect layer 2, and the second shoe upper effect layer 7.

[0033] The working principle of this invention: The shoe upper is made of textile yarns with nano-closed-cell materials, creating a nano-closed-cell insulation system. Because the pore size of the nano-closed cells is extremely small and evenly distributed within the upper fabric at a microscopic level, unlike traditional fly-knit uppers which rely on open mesh structures, the nano-closed-cell structure fundamentally changes the heat transfer characteristics of the shoe upper. The nano-closed cells effectively inhibit heat loss through conduction and convection, significantly reducing the rate at which heat dissipates from the feet, allowing the interior of the upper to maintain a relatively warm environment for a long time. The nano-closed cells are also resistant to external cold. The air forms an efficient barrier, greatly reducing the possibility of cold air penetrating the shoe upper and entering the shoe. Even in cold and harsh external environments, it can provide good warmth and protection for the feet. The breathable sports fabric in the breathable part, combined with the nano-closed-pore structure, is not completely sealed. Instead, it allows for a certain amount of air exchange at the microscopic level while ensuring heat and cold air are blocked, keeping the feet dry and avoiding stuffiness. Furthermore, the softness and foot-fitting characteristics of the flyknit technology itself are still retained. Wearers can enjoy the warmth without feeling foot discomfort, thus improving overall comfort.

[0034] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions provided are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of protection of this utility model as defined by the appended claims and their equivalents.
