[0023] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0024] Example: See Figures 1 to 3 According to an embodiment of the present invention, a technical solution is provided: a TPU flywoven upper, comprising: an upper body 1, the upper body 1 is made of TPU material, a first breathable area 2 is provided on the surface of the upper body 1, a second breathable area 11 is provided outside the first breathable area 2, a first breathable hole 3 is opened on the surface of the first breathable area 2, a second breathable hole 4 is opened on the surface of the second breathable area 11, the aperture of the second breathable hole 4 is smaller than the aperture of the first breathable hole 3, and a mesh surface 8 is connected to the bottom of the first breathable area 2 and the second breathable area 11.
[0025] The TPU material of the above structure has the characteristics of being soft, durable, wear-resistant and easy to hot-press mold. The soft texture can ensure comfort when wearing and will not cause excessive friction or extrusion on the feet; the durability and wear-resistant performance enable the upper to withstand the test of frequent use such as daily walking and various sports, thereby extending the service life of the shoes; the easy hot-press moldability makes it convenient to manufacture the upper into an ergonomic shape that fits the curve of the foot, providing a good wrapping feeling and support. When the feet sweat or the temperature inside the shoe rises, the first breathable area 2 can quickly discharge heat and moisture out of the shoe to maintain a dry and comfortable environment inside the shoe, so that the feet can be in a relatively comfortable state. Its breathable effect is particularly important when exercising for a long time or wearing in hot weather. The surface of this area is provided with a second The first ventilation hole 3 has a relatively large aperture. The larger aperture is conducive to the rapid circulation of air and the rapid dissipation of water vapor, just like opening a large "ventilation hole" on the shoe upper, which can efficiently discharge the heat and sweat accumulated in the shoe and achieve good ventilation effect. The second ventilation area 11 is located outside the first ventilation area 2, and plays a role of auxiliary ventilation and working in conjunction with the first ventilation area 2. On the one hand, it can further expand the ventilation range of the entire shoe upper, increase the total ventilation area, and improve the overall ventilation performance of the shoe upper; on the other hand, due to its relatively outside position, it can also guide and disperse the heat and moisture discharged from the first ventilation area 2 to a certain extent, so that it can be more smoothly dissipated into the external environment, and at the same time prevent external water stains from entering the shoe.
[0026] In this embodiment, small exhaust holes 9 are provided below the mesh surface 8 at the first breathable area 2 on the inner surface of the upper body 1, and large exhaust holes 10 are provided below the mesh surface 8 at the second breathable area 11 on the inner surface of the upper body 1. Skin areas 5 are provided on both sides of the upper body 1, and a waterproof layer is provided on the surface of the skin area 5. A first cutting edge 6 is provided below the skin area 5, and a second cutting edge 7 is provided at the front end of the upper body 1. The surface of the upper body 1 is coated with a polyurethane coating.
[0027] Small exhaust holes 9 are set below the mesh surface 8 at the first breathable area 2 on the inner surface of the upper body 1 in order to further optimize the air circulation and moisture discharge mechanism inside the upper. When the foot generates heat and sweat, the heat will first be dissipated outward through the first breathable holes 3 with larger apertures in the first breathable area 2 on the outer layer of the upper. These small exhaust holes 9 can help guide the hot and humid air closer to the foot in the shoe more smoothly to the outer layer of the upper, and cooperate with the outer layer breathable holes to form a more efficient and three-dimensional air and moisture discharge channel from the inside of the shoe to the outside of the shoe. Its smaller size design helps to control the air flow more accurately, avoid the discomfort caused by excessive air convection, and also prevent to a certain extent To prevent external water stains from entering the shoe, the small exhaust holes 9 work together with the first ventilation area 2 and the corresponding mesh 8 above to enhance the ventilation performance of the entire upper in this key ventilation part, so that the air around the foot can always remain fresh, improving the comfort of wearing. Since the second ventilation holes 4 in the second ventilation area 11 itself have a relatively small aperture, its ventilation speed may be relatively slow, and the large exhaust holes 10 below can make up for this deficiency and speed up the speed of discharging heat and moisture from the shoe in this area. The large exhaust holes 10 cooperate with the second ventilation area 11 and the corresponding mesh 8 to further expand the ventilation range and enhance the ventilation strength, making the ventilation function of the entire upper more uniform and comprehensive, avoiding the occurrence of The present local poor ventilation situation, so that the wearer in different sports postures and foot position changes, can feel a good ventilation experience, the surface of the skin area 5 set on the left and right sides of the upper body 1 increases the waterproof layer, the waterproof layer can effectively block the invasion of external moisture, prevent the shoe from getting wet, keep the feet dry, and avoid problems such as damage to the upper material, breeding bacteria or odor caused by moisture entering. The first cutting edge 6 and the second cutting edge 7 can facilitate mass production. During the production process, it may be necessary to cut the material used to make the skin area 5 to make it meet the designed size and shape requirements. The edge left after cutting is the first cutting edge 6. Although it is a Although the shoe body 1 has a plurality of shoe uppers, the shoe body 1 has a plurality of shoe uppers and a plurality of shoe uppers. The shoe body 1 has a plurality of shoe uppers and a plurality of shoe uppers. The shoe body 1 has a plurality of shoe uppers and a plurality of shoe uppers.

The shoe body 1 has a plurality of shoe uppers and a plurality of shoe uppers. The shoe body 1 has a plurality of shoe uppers and a plurality of shoe uppers.In addition, the position and shape of the cutting edge of the front end will also affect the overall wearing experience of the shoe. A suitable design can provide the foot with more comfortable stretching space in the shoe without feeling cramped or squeezed. Coating a polyurethane coating on the surface of the upper body 1 can further enhance the waterproof performance of the upper, and cooperate with the waterproof layer of the epidermal area 5 to form a more comprehensive and reliable waterproof barrier, thereby improving the overall ability of the upper to resist external moisture intrusion. At the same time, the polyurethane coating can enhance the wear resistance of the upper, making it less likely for the upper to be worn, scratched, etc. when rubbing against the ground or other objects during daily walking and exercise, thereby extending the service life of the upper.
[0028] Working principle:
[0029] When the foot generates heat and sweat in the shoe, the hot and humid air in the shoe will first gather to the small exhaust holes 9 under the mesh surface 8 at the first breathable area 2 on the inner surface of the upper body 1. These small exhaust holes 9 are relatively small in size and can accurately control the air flow, guiding the hot and humid air close to the foot to the position of the first breathable area 2 on the outer layer of the upper at a suitable speed. The surface of the first breathable area 2 is provided with first breathable holes 3 with relatively large apertures. The hot and humid air transported by the small exhaust holes 9 will be quickly discharged into the environment outside the shoe through these larger "ventilations". In this way, an efficient, three-dimensional air and moisture discharge channel is formed from the inside of the shoe near the foot to the outer layer of the upper and then to the external environment, which realizes the rapid discharge of heat and moisture and keeps the inside of the shoe cool. The shoe has a dry and comfortable effect. At the same time, the mesh surface 8 connected to the lower part of the first breathable area 2 also plays an auxiliary role. It has a certain gap, which is helpful for the air to circulate and circulate better inside the upper, and further promotes the hot and humid air to gather and be discharged to the air holes, thereby enhancing the breathability of the key breathable part of the entire upper; the hot and humid air generated by the foot will also flow to the large exhaust holes 10 below the mesh surface 8 corresponding to the second breathable area 11. The large exhaust holes 10 will quickly gather the hot and humid air in the shoe in this area and transport it to the second breathable area 11. Although the aperture of the second air holes 4 on the surface of the second breathable area 11 is small, the air transport speed accelerated by the large exhaust holes 10 below can allow air and water vapor to pass through the second air holes 4 and be discharged out of the shoe. Furthermore, the second breathable area 11 is located outside the first breathable area 2. This not only expands the breathable range of the entire upper, increasing the total breathable area, but also guides and disperses the heat and moisture exhausted from the first breathable area 2, allowing the exhausted air to be released more smoothly into the external environment. This makes the ventilation function of the entire upper more uniform and comprehensive, ensuring a good ventilation experience regardless of the wearer's different exercise postures and foot positions.
[0030] The waterproof layer on the surface of the epidermal area 5 arranged on the left and right sides of the upper body 1 is the first line of defense against the intrusion of external moisture. When encountering rain, dew or other water stains, the waterproof layer, with its own waterproof properties, prevents moisture from penetrating into the shoe from both sides of the upper, thereby protecting the inside of the shoe from being damaged by moisture, breeding bacteria or producing odor. The polyurethane coating applied on the surface of the upper body 1 further enhances the waterproof function. It cooperates with the waterproof layer in the epidermal area 5 to form a more comprehensive and reliable waterproof barrier, covering other parts of the upper, blocking possible moisture penetration paths, and comprehensively improving the overall ability of the upper to resist the intrusion of external moisture, ensuring a dry environment inside the shoe to the greatest extent.
