Description

Technical Field

[0001] This utility model belongs to the field of footwear technology, specifically relating to a lightweight, oil-resistant cowhide footwear. Background Technology

[0002] Footwear, as essential equipment for daily wear and specific work scenarios, is widely used in industrial production (such as machining, auto repair, and chemical processing), catering services, and outdoor work. In these scenarios, footwear often faces problems such as oil stains, punctures from sharp objects, and fatigue from prolonged walking.

[0003] Traditional cowhide leather shoes and boots are usually not treated with oil-proofing or only have a simple waxing process. Oil stains can easily seep into the leather fibers and penetrate into the shoe, making them not only difficult to clean, but also causing the leather to harden and crack, shortening the lifespan of the shoes and boots. At the same time, oil stains can also reduce the dryness of the shoe upper surface, affecting the wearing experience. Some oil-proof shoes and boots use a thick resin coating, which can block oil stains to a certain extent, but it sacrifices the breathability of the leather and increases the weight of the shoe upper, resulting in stuffiness and bulkiness when worn. Utility Model Content

[0004] The purpose of this invention is to provide a lightweight, oil-resistant cowhide leather shoe to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a lightweight oil-resistant cowhide leather shoe, comprising an upper and a sole, wherein the upper comprises an oil-resistant cowhide leather layer, a cowhide fiber felt layer and a cowhide suede layer bonded sequentially from the outside to the inside, and the sole comprises an oil-resistant cushioning midsole, an oil-resistant cushioning outsole and a puncture-resistant support piece bonded between the oil-resistant cushioning midsole and the oil-resistant cushioning outsole.

[0006] In a preferred embodiment, the surface of the oil-resistant cowhide layer is provided with a fluorocarbon nano-oil-resistant coating.

[0007] In a preferred embodiment, the cowhide fiber felt layer is a three-dimensional mesh structure formed by needle punching, and the interior of the cowhide fiber felt layer is filled with micro air bladders.

[0008] In a preferred embodiment, the oil-resistant cushioning insole is made of EVA foam material, and the interior of the oil-resistant cushioning insole has a honeycomb structure.

[0009] In a preferred embodiment, the oil-resistant cushioning outsole is made of polyurethane modified material, and the bottom surface of the oil-resistant cushioning outsole is provided with interlaced serrated patterns and drainage grooves.

[0010] In a preferred embodiment, the puncture-resistant support sheet is made of an ultra-thin carbon fiber reinforced kraft paper composite material.

[0011] Compared with the prior art, the beneficial effects of this utility model are: These lightweight, oil-resistant cowhide leather shoes feature an oil-resistant cowhide leather layer and a fluorocarbon nano-oil-resistant coating that reduces surface tension, preventing oil stains from seeping in or penetrating, thus enhancing the oil-resistant effect of the shoe upper. The mesh structure of the cowhide fiber felt and the micro-airbags absorb the impact of walking, providing cushioning and shock absorption. The napped structure on the surface of the cowhide suede layer reduces friction between the shoe upper and the foot, and also absorbs foot sweat, transferring it to the cowhide fiber felt layer for evaporation, thus improving the comfort of the shoes. These lightweight, oil-resistant cowhide leather shoes feature a honeycomb-structured oil-resistant cushioning midsole that reduces weight and distributes pressure, providing cushioning for the soles of the feet. The fluororubber particles in the oil-resistant cushioning outsole increase the coefficient of friction in oily environments and improve wear resistance compared to traditional rubber outsoles. The puncture-resistant support plate prevents sharp objects from penetrating the sole, protecting the feet and preventing injuries. This lightweight, oil-resistant, and puncture-resistant design achieves its intended effect. Attached Figure Description

[0014] The present invention will be further described below with reference to the embodiments.

[0015] The following embodiments are used to illustrate the present invention, but should not be used to limit the scope of protection of the present invention. The conditions in the embodiments can be further adjusted according to specific conditions, and simple improvements to the method of the present invention under the concept of the present invention are all within the scope of protection claimed by the present invention.

[0016] Please see Figure 1-3This utility model provides a lightweight, oil-resistant cowhide leather shoe, including an upper 1 and a sole 2. The upper 1 includes an oil-resistant cowhide leather layer 11, a cowhide fiber felt layer 12, and a cowhide suede layer 13, bonded sequentially from the outside to the inside. The surface of the oil-resistant cowhide leather layer 11 is provided with a fluorocarbon nano-oil-resistant coating 111. The fluorocarbon nano-oil-resistant coating 111 can reduce surface tension, preventing oil stains from wetting or penetrating, thereby improving the oil-resistant effect of the upper 1 surface. The cowhide fiber felt layer 12 is a three-dimensional mesh structure formed by needle punching. The interior is filled with micro-airbags 121. The mesh structure of the cowhide fiber felt and the micro-airbags 121 can absorb the impact of walking and play a cushioning and shock-absorbing role. The surface of the cowhide suede layer 13 is napped to form a soft nap structure, which is bonded to the cowhide fiber felt layer 12 with adhesive to reduce the friction between the shoe upper 1 and the foot. The nap structure can absorb foot sweat and transfer it to the cowhide fiber felt layer 12 for evaporation. In addition, the cowhide suede material is treated with silver ion antibacterial agent, which has antibacterial function, inhibits bacterial growth, and improves the comfort of the shoes.

[0017] The sole 2 includes an oil-resistant cushioning midsole 21, an oil-resistant cushioning outsole 22, and a puncture-resistant support piece 23 bonded between the oil-resistant cushioning midsole 21 and the oil-resistant cushioning outsole 22. The oil-resistant cushioning midsole 21 is made of EVA foam material and has a honeycomb structure inside. The honeycomb structure of the oil-resistant cushioning midsole 21 has a weight-reducing effect and can distribute pressure, providing a cushioning effect for the sole of the foot. The oil-resistant cushioning outsole 22 is made of polyurethane modified material, which is made by adding fluororubber particles to polyurethane material. The fluororubber particles increase the coefficient of friction in oily environments and also improve wear resistance compared to traditional rubber outsoles. The bottom surface of the oil-resistant cushioning outsole 22 is provided with interlaced serrated patterns and drainage grooves. The puncture-resistant support piece 23 is made of ultra-thin carbon fiber reinforced kraft paper composite material, which is made by adding 15% carbon fiber during the production of kraft paper. The puncture-resistant support piece 23 can resist the penetration of sharp objects into the sole 2, protecting the sole of the foot and preventing injury to the user's feet.

[0018] The working principle and usage process of this utility model are as follows: First, through the setting of the oil-resistant cowhide layer 11, the fluorocarbon nano oil-resistant coating 111 can reduce the surface tension, so that oil stains do not wet or penetrate, thereby improving the oil-resistant effect of the shoe upper 1. The cowhide fiber felt with mesh structure and the micro airbags 121 can absorb the impact of walking, so as to play a cushioning and shock-absorbing role. The nap structure on the surface of the cowhide suede layer 13 can reduce the friction between the shoe upper 1 and the foot, and can also absorb the sweat of the foot and transfer it to the cowhide fiber felt layer 12 for evaporation, thereby improving the comfort of the shoes. The honeycomb structure oil-resistant cushioning midsole 21 has a weight-reducing effect and can distribute pressure, so as to play a cushioning role on the sole of the foot. The fluororubber particles in the oil-resistant cushioning outsole 22 increase the friction coefficient in the oily environment, and at the same time improve the wear resistance compared with the traditional rubber outsole. The puncture-resistant support piece 23 can resist the penetration of sharp objects into the sole 2, so as to protect the sole of the foot and avoid injury to the user's foot.
