Description

Technical Field

[0001] This utility model relates to the field of leather products and footwear technology, and in particular to a high-performance microfiber leather base for sports shoes. Background Technology

[0002] With the booming development of the athletic shoe market, consumers have increasingly higher expectations for footwear performance. Traditional natural leather athletic shoe leather resources are limited, resulting in high costs and inconsistent physical properties.

[0003] Ordinary synthetic leather often struggles to achieve key properties such as breathability, waterproofing, wear resistance, and slip resistance, resulting in a poor wearing experience. During exercise, feet sweat profusely, leading to stuffiness, dampness, discomfort, and bacterial growth; wet shoes easily become damp, hindering movement; and friction from walking, running, and jumping causes rapid wear and tear on the soles. Therefore, there is an urgent need to develop a sports shoe leather with a microfiber leather base that integrates multiple superior functions to fill a market gap and improve the overall quality of sports shoes. Utility Model Content

[0004] The main objective of this invention is to provide a high-performance microfiber leather base for athletic shoes, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A high-performance microfiber leather base sports shoe leather includes a base, a waterproof functional layer, and an abrasion-resistant coating. A breathable functional layer is provided on the top of the base, and the upper end of the breathable functional layer is covered with a number of breathable micropores. The waterproof functional layer covers the breathable functional layer and has a contact angle of not less than 120°. The abrasion-resistant coating is provided on the side of the shoe leather that contacts the ground and has an anti-slip texture.

[0007] The waterproof functional layer includes an outer frame layer and several waterproof layers, with the outer frame layer located on the outermost layer and closely bonded to the inner layers of several waterproof layers.

[0008] Preferably, a plurality of the breathable micropores are arranged in a rectangular array at the upper end of the breathable functional layer, and the pore diameter of each of the breathable micropores is 1 μm.

[0009] By adopting the above technical solution, breathable micropores are distributed in a rectangular array on the upper part of the breathable functional layer. The orderly layout allows moisture generated in various areas inside the shoe to have a smooth way to escape. The 1μm pore size is moderate, neither too large to allow foreign objects to enter, nor too small to ensure that gas and moisture can pass through quickly, allowing heat from the feet to dissipate in time and keeping the inside of the shoe dry and comfortable at all times.

[0010] Preferably, the anti-slip texture is distributed in a crisscrossing grid pattern, with the grid lines having a width of 0.5-1.5mm.

[0011] By adopting the above technical solution, this grid-like texture design offers superior wear resistance compared to unidirectional patterns. Friction generated from daily walking, frequent turning, or high-intensity exercise is distributed across the intersecting lines, preventing any single area from wearing out too quickly. This maintains good anti-slip properties for a long time, extending the effective lifespan of the shoe leather.

[0012] Preferably, the plurality of waterproof layers consists of eight layers, with adjacent layers using different spraying processes.

[0013] By adopting the above technical solution, eight waterproof layers are set up, stacked one on top of the other to build multiple lines of defense, greatly increasing the difficulty of water penetration. Adjacent layers use different spraying processes; for example, one layer uses high-pressure airless spraying to ensure uniform coating, while the other layer uses electrostatic spraying to improve adhesion. This creates a complementary relationship between the layers, making the overall waterproof structure dense and seamless, and significantly enhancing waterproof performance.

[0014] Preferably, the outer frame layer has a thickness of 0.03 mm, providing a stable enclosure for the inner waterproof layer.

[0015] By adopting the above technical solution, the outer frame layer with a thickness of 0.03mm tightly wraps the inner waterproof layer, like a sturdy "armor", providing reliable support for the waterproof layer, resisting the impact of external physical compression and friction, preventing the waterproof layer from wrinkling or breaking, maintaining the integrity of the waterproof layer, and ensuring the stable performance of the waterproof function.

[0016] Preferably, the wear-resistant coating surface is treated with an oleophobic coating, and the contact angle with common oil stains is greater than 110°.

[0017] By adopting the above technical solution: oil stains are corrosive, and long-term adhesion will erode the wear-resistant coating and weaken its wear resistance. The protective barrier formed by the oleophobic treatment avoids oil stain erosion, maintains the stability of the coating's physical structure, and allows the wear-resistant coating to continue to perform its wear-resistant function in complex environments, thus extending the service life of the shoes and leather.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. This utility model integrates key performance characteristics such as breathability, waterproofing, wear resistance, and slip resistance into one unit. The breathable micropores are distributed in a rectangular array with a precisely designed pore size, efficiently expelling moisture from inside the shoe, keeping it dry, and inhibiting bacterial growth. Multiple waterproof layers combined with a sturdy outer frame ensure tight waterproofing, making it suitable for humid environments. The wear-resistant coating and slip-resistant texture work together to provide strong grip while resisting wear, adapting to various sports scenarios.

[0020] 2. This utility model uses a microfiber leather base, solving the problems of high cost and uneven performance of natural leather. The microfiber leather base, combined with scientific processes, ensures overall stability and durability. While reducing costs, it also improves the ease of surface cleaning through fine processes such as oleophobic treatment, allowing the sports shoes to have both a high-quality wearing experience and an affordable market price advantage.

[0028] Please see Figure 1-3 This utility model provides a technical solution:

[0029] A high-performance microfiber leather-based athletic shoe leather includes a base 1, a waterproof functional layer 4, and an abrasion-resistant coating 5. A breathable functional layer 2 is disposed on the top of the base 1, and the upper end of the breathable functional layer 2 is covered with a number of breathable micropores 3. The waterproof functional layer 4 is covered on the breathable functional layer 2, with a contact angle of not less than 120°. The abrasion-resistant coating 5 is disposed on the side of the shoe leather that contacts the ground and has an anti-slip texture 6. The waterproof functional layer 4 includes an outer frame layer 41 and a number of waterproof layers 42. The outer frame layer 41 is located on the outermost layer and is tightly bonded to the inner layers of several waterproof layers 42.

[0030] Through the above scheme, the heat and moisture generated by the feet diffuse upwards, at which point the breathable functional layer 2 begins to function. The upper part of the breathable functional layer 2 is covered with numerous breathable micropores 3, arranged in a specific pattern. These micropores have suitable diameters, forming channels for moisture to escape. The hot and humid air inside the shoe can pass through the breathable micropores 3 and continuously escape to the outside, keeping the feet dry. When encountering water, such as walking on puddles or getting wet in the rain, the water comes into contact with the waterproof functional layer 4 on the surface of the leather. The waterproof functional layer 4 has a contact angle greater than 120°, causing water droplets to quickly roll off its surface, making it difficult for them to adhere and penetrate. The outermost outer frame layer 41 firmly wraps around the inner layers of several waterproof layers 42. The multiple waterproof layers 42 are tightly bonded to each other, relying on different waterproof mechanisms and coating properties to further prevent moisture from seeping into the shoe from the outside, providing comprehensive protection for dry feet. During exercise, the leather frequently rubs against the ground, and the abrasion-resistant coating 5 on the side of the leather in contact with the ground bears the main frictional force, protecting the leather from excessive wear. The anti-slip texture 6 on the wear-resistant coating 5, with its specific shape and distribution, can increase friction when in contact with the ground, allowing the sole to firmly "grip" the ground, preventing the wearer from slipping and ensuring safety during walking and sports.

[0031] In this embodiment, a number of breathable micropores 3 are arranged in a rectangular array on the upper end of the breathable functional layer 2, and the pore diameter of each of the breathable micropores 3 is 1μm; the anti-slip texture 6 is arranged in a crisscross grid pattern, and the grid line width is 0.5-1.5mm; there are eight waterproof layers 42, and adjacent layers are coated with different processes; the outer frame layer 41 is 0.03mm thick, providing a stable wrapping for the inner waterproof layer 42; the wear-resistant coating 5 has an oleophobic coating, and the contact angle with common oil stains is greater than 110°.

[0032] Through the above scheme: During exercise, moisture generated on the feet is expelled through the breathable micropores 3, which are arranged in a rectangular array with a pore size of 1μm, on the upper part of the breathable functional layer 2. The regular layout and appropriate pore size ensure efficient breathability. When exposed to water, the water comes into contact with the waterproof functional layer 4. The eight waterproof layers 42 form a dense waterproof system due to the different spraying processes of adjacent layers. The 0.03mm thick outer frame layer 41 firmly wraps around the waterproof layer 42, preventing water penetration with its large contact angle. During walking or exercise, the wear-resistant coating 5 withstands friction. Its oleophobic treatment prevents oil stain corrosion, and the crisscrossing anti-slip texture 6, 0.5-1.5mm wide, is embedded in the ground to enhance grip.

[0033] It should be noted that this utility model is a high-performance microfiber leather-based sports shoe leather. During use, firstly, the heat and moisture generated by the feet during exercise diffuse upwards and pass through the breathable functional layer 2 above the base 1. The upper end of the breathable functional layer 2 has a rectangular array of breathable micropores 3 with a pore size of 1μm, which act like tiny channels, allowing moisture to be quickly discharged to the outside of the shoe, keeping the air inside the shoe fresh and dry. When encountering external moisture, such as rain or puddles, the waterproof functional layer 4 covering the breathable functional layer 2 begins to function. The outermost outer frame layer 41 is 0.03mm thick and tightly wraps the inner eight waterproof layers 42. Adjacent layers use different spraying processes, so that when water comes into contact with the surface of the leather, the water droplets quickly roll off because the contact angle is not less than 120°, preventing them from penetrating into the shoe. During activities such as walking, running, and jumping, the leather frequently rubs against the ground, and the wear-resistant coating 5 on the side of the leather in contact with the ground bears the main frictional stress. Its surface is treated with an oleophobic coating, so it is not afraid of oil stains. It also has an anti-slip texture with a grid pattern and a grid line width of 0.5-1.5mm, which reduces its own wear and firmly grips the ground to prevent slipping.

[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 in the specification 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 the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
