Description

Technical Field

[0001] This utility model relates to the field of cow leather technology, specifically to a high-quality cow leather. Background Technology

[0002] Leather products have extremely wide applications in people's daily lives, industrial production, and many specialized fields. From everyday fashion consumer goods such as leather shoes, bags, and clothing, to furniture such as car seats and sofas, and even to specialized fields with extremely high performance requirements such as aerospace and military equipment, leather has become an indispensable material due to its unique texture, good flexibility, and a certain degree of durability.

[0003] With rising living standards and technological advancements, consumers are placing increasingly stringent demands on the performance of leather products. They not only expect leather to have an attractive appearance but also require significant improvements in tensile strength, abrasion resistance, breathability, comfort, and lifespan. For example, in athletic footwear, consumers want leather uppers that can withstand the tension and friction of strenuous exercise while keeping feet dry and comfortable; in automotive interiors, they require leather seats to remain in good condition without cracking or separating after long-term use. However, existing leather technologies and products struggle to fully meet these growing needs.

[0004] The existing ventilation hole design for leather has significant flaws. Many leathers have a simple ventilation hole structure, failing to simultaneously function as a barrier against dust and a conduit for airflow. While excessively large surface pores facilitate air movement, they also allow large particles of dust and dirt to easily penetrate the leather, contaminating it and damaging its properties. Conversely, excessively small surface pores hinder airflow, leading to moisture buildup, stuffiness, and unpleasant odors, reducing comfort and hygiene. For example, some low-quality leather seats, after prolonged use, may develop mold due to trapped moisture, producing an unpleasant smell. Utility Model Content

[0005] In view of the shortcomings of the prior art, this utility model provides a high-quality cow leather, which solves the problems mentioned in the background art.

[0006] The solution to the above-mentioned technical problems provided by this utility model is as follows: A high-quality cowhide includes: a leather body composed of an upper hide and a lower hide, wherein multiple stitching holes are provided through the upper hide and the lower hide, and the upper hide and the lower hide are connected and fixed through the stitching holes and sutures. The stitching holes are arrayed on the upper hide and the lower hide, and uniformly divide the leather body into multiple buffer units. Each buffer unit is filled with a buffer block, and each buffer block has a perforated vent hole with a gradient pore size. The grain layer of the upper hide and the lower hide extends downward to form barbed collagen fibers, which are embedded in the fiber gaps of the buffer block to form a physical lock. A wear-resistant protrusion is provided at the intersection of two adjacent buffer units, and the wear-resistant protrusion is higher than the buffer unit.

[0007] Based on the above technical solution, the present invention can be further improved as follows.

[0008] Furthermore, the wiring holes are distributed in a hexagonal array on the upper and lower skin embryos.

[0009] The beneficial effects of adopting the above-mentioned further solutions are: The hexagonal array of perforations allows the stitching thread to evenly distribute external force throughout the leather when connecting the upper and lower hides. When the leather is subjected to tensile or other external forces, each perforation and the stitching thread share the force, preventing localized stress concentration. This significantly enhances the tightness and stability of the connection between the upper and lower hides, greatly improves the overall tensile strength of the leather, effectively reduces the probability of cracking or separation during use, and extends the leather's lifespan.

[0010] Furthermore, the vent holes are inverted funnel-shaped gradient pores.

[0011] The beneficial effects of adopting the above-mentioned further solutions are: The inverted funnel-shaped, gradually widening pore structure effectively prevents larger particles such as dust and dirt from entering the leather, keeping the interior clean and hygienic. The gradually widening pores facilitate airflow; when a pressure difference exists between the inside and outside of the leather, air can smoothly enter and exit through the pores, achieving good gas exchange. This keeps the leather dry during use, reducing stuffiness and odor, and improving comfort and hygiene.

[0012] Furthermore, the surface pore size of the vent is 2-3 μm, gradually changing to 8-10 μm towards the core layer.

[0013] The beneficial effects of adopting the above-mentioned further solutions are: The 2-3μm pore size on the surface layer allows for precise filtration, effectively blocking most dust and tiny impurities from entering the leather and preventing contamination and damage. The pore size gradually increases to 8-10μm towards the core layer, significantly improving airflow efficiency. This allows for more thorough gas exchange between the leather's interior and the outside environment, quickly expelling moisture and odors from within the leather, keeping it dry and fresh, and further enhancing user comfort.

[0014] Furthermore, the edges of the leather body are edged.

[0015] The beneficial effects of adopting the above-mentioned further solutions are: As an additional protective layer, binding helps to withstand some of the external force when the leather edges collide or rub against other objects, reducing direct impact and wear on the edges. It prevents the leather fibers from breaking or pilling, keeping the edges neat and smooth, and avoiding damage to the overall structure of the leather due to edge damage. This effectively extends the lifespan of the leather and enhances its overall appearance and quality.

[0016] Furthermore, the buffer block is made of a porous elastic material, and the buffer block is fixedly connected to the upper and lower skin embryos through the physical locking.

[0017] The beneficial effects of adopting the above-mentioned further solutions are: The porous elastic material cushioning block possesses excellent elasticity and cushioning properties. When leather is subjected to external impact, it can absorb and disperse energy through its own deformation, effectively cushioning the leather and protecting it from excessive damage. Furthermore, its physical locking mechanism for fixing it to the upper and lower leather blanks eliminates the need for additional chemical adhesives, making it more environmentally friendly and healthier. This connection method is also strong and reliable, preventing loosening and ensuring a tight bond between the cushioning block and the leather, maintaining stable cushioning performance over long-term use.

[0018] Furthermore, the wear-resistant bumps are made of wear-resistant polymer, and the wear-resistant bumps are fixed to the intersection of the buffer unit by adhesive or molding.

[0019] The beneficial effects of adopting the above-mentioned further solutions are: The abrasion-resistant polymer material used for the abrasion-resistant bumps provides high hardness and abrasion resistance. When the leather rubs against other surfaces, these bumps absorb the friction force first, effectively resisting wear and protecting the underlying cushioning unit and the leather itself from excessive abrasion. Fixed to the intersections of the cushioning unit via adhesive or molding, the bumps are precisely positioned and firmly secured, ensuring long-term abrasion resistance, reducing damage to the leather caused by frequent friction, extending the leather's lifespan, and improving its durability.

[0020] Furthermore, the suture is a high-strength fiber thread, and the diameter of the suture hole matches the suture to ensure a tight connection between the epidermal embryo and the hypodermal embryo.

[0021] The beneficial effects of adopting the above-mentioned further solutions are: High-strength fiber threads possess excellent tensile strength and abrasion resistance, enabling them to withstand significant external forces without easily breaking. The diameter of the stitching holes matches the suture thread, allowing it to pass tightly through the holes and ensuring a secure and reliable connection between the upper and lower leather pieces. This matching design allows the suture thread to fully utilize its strength, tightly binding the upper and lower leather pieces together and effectively preventing problems such as delamination and cracking during use due to weak connections, thus improving the overall structural stability and durability of the leather.

[0022] This invention provides a high-quality cowhide leather. It has the following beneficial effects: Multiple hexagonal arrayed perforations are drilled through the upper and lower leather embryos, with the diameter of the perforations matching that of the high-strength fiber threads (sutures). The working principle of this design is that the hexagonal array of perforations allows the sutures to evenly distribute force throughout the leather when connecting the upper and lower embryos. When the leather is stretched, each perforation and suture shares the force, avoiding localized stress concentration. This ensures the tightness and stability of the connection between the upper and lower embryos, significantly improving the overall tensile strength of the leather and reducing the risk of cracking or separation during use. The grain layer of the upper and lower embryos extends downwards to form barbed collagen fibers. These fibers embed into the fiber gaps of the cushioning block, creating a physical lock. The working principle is that the interaction force between the barbed collagen fibers and the cushioning block fibers acts like countless tiny hooks interlocking, tightly binding the cushioning block to the upper and lower embryos. This physical locking method does not require additional chemical adhesives, making it not only more environmentally friendly but also providing a strong and secure connection that is not easily loosened. It effectively prevents the cushioning block from separating from the leather body during use, ensuring the integrity of the leather structure.

[0023] The leather body is evenly divided into multiple cushioning units by stitching holes, each filled with a porous elastic material cushioning block. When the leather is subjected to external impact, the cushioning block absorbs and disperses energy through its porous structure and elastic properties. The porous structure allows the cushioning block to deform under pressure, converting the impact force into elastic potential energy for storage, and then returning to its original shape when the external force disappears. Multiple cushioning units work independently yet cooperate with each other, providing comprehensive cushioning against impacts from different directions, effectively protecting items or people under the leather from excessive vibration and impact, thus improving the leather's cushioning performance and user comfort.

[0024] The ventilation holes running through the buffer block are inverted funnel-shaped with a gradually increasing pore size. The surface pores are 2-3 μm in diameter, gradually increasing to 8-10 μm towards the core. This design works by using smaller surface pores to filter out larger particles like dust and dirt, keeping the leather clean. The gradually increasing pore size towards the core facilitates airflow. When a pressure difference exists between the inside and outside of the leather, air can flow smoothly through the pores, achieving good gas exchange. This keeps the leather dry during use, reducing stuffiness and odor, and improving comfort and hygiene.

[0025] At the intersection of two adjacent cushioning units, abrasion-resistant protrusions, higher than the cushioning units themselves, are installed. These protrusions are made of abrasion-resistant polymer and are fixed by adhesive or molding. When the leather rubs against other surfaces, the abrasion-resistant protrusions primarily bear the frictional force. Due to the high hardness and abrasion resistance of their polymer material, they effectively resist wear caused by friction, protecting the underlying cushioning units and the leather itself from excessive wear. Furthermore, because the abrasion-resistant protrusions are higher than the cushioning units, during friction, it is primarily the protrusions that come into contact with the contact surface, reducing the chance of friction on other parts of the leather and thus extending the overall lifespan of the leather.

[0026] An edging is installed along the edges of the leather body. The edging works by acting as an extra protective layer. When the leather edges collide or rub against other objects, the edging can withstand some of the external force, reducing direct impact and wear on the edge areas. It prevents the leather fibers from breaking and pilling, keeping the edges neat and smooth, avoiding damage to the overall structure of the leather due to edge damage, and further extending the leather's lifespan.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Please see Figures 1 to 3 As shown, the embodiments provided by this utility model are as follows: Example 1: A high-quality cowhide leather, comprising: a leather body 1, which is composed of an upper leather blank 104 and a lower leather blank 107. Multiple thread holes 103 are provided through the upper leather blank 104 and the lower leather blank 107. The upper leather blank 104 and the lower leather blank 107 are connected and fixed by the thread holes 103 and stitching. The thread holes 103 are arrayed on the upper leather blank 104 and the lower leather blank 107, uniformly dividing the leather body 1 into multiple buffer units 101. Each buffer unit 101 is filled with a buffer block 106. A ventilation hole 105 is provided through the buffer block 106, and the ventilation hole 105 has a gradient porosity. The grain layer of the upper leather blank 104 and the lower leather blank 107 extends downwards to form barbed collagen fibers. These barbed collagen fibers are embedded in the fiber gaps of the buffer block 106, forming a physical lock. A wear-resistant protrusion 2 is provided at the intersection of two adjacent buffer units 101, and the wear-resistant protrusion 2 is higher than the buffer unit 101.

[0032] Example 2: To further optimize leather performance, for example, such as Figures 1 to 3 As shown, this utility model also includes: The stitching holes 103 are arranged in a hexagonal array on the upper leather blank 104 and the lower leather blank 107. The hexagonal array of stitching holes 103 allows the suture thread to evenly distribute the external force to all parts of the leather when connecting the upper leather blank 104 and the lower leather blank 107. When the leather is subjected to external forces such as tension, each stitching hole 103 and the suture thread share the force, avoiding local stress concentration. This significantly enhances the tightness and stability of the connection between the upper leather blank 104 and the lower leather blank 107, greatly improves the overall tensile strength of the leather, effectively reduces the probability of cracking and separation during use, and extends the service life of the leather.

[0033] The ventilation holes 105 are inverted funnel-shaped gradient pores. This structure, with smaller openings on the surface, effectively prevents larger particles like dust and dirt from entering the leather, maintaining its cleanliness. The gradually increasing size of the pores facilitates airflow. When a pressure difference exists between the inside and outside of the leather, air can smoothly enter and exit through these gradient pores, achieving good gas exchange. This keeps the leather dry during use, reducing stuffiness and odor, and improving comfort and hygiene.

[0034] The surface pores of the 105 breathable vent have a diameter of 2-3 μm, gradually increasing to 8-10 μm towards the core layer. The 2-3 μm pores on the surface layer can precisely filter and effectively prevent most dust and tiny impurities from entering the leather, thus preventing them from contaminating and damaging the leather. The gradually increasing pore size to 8-10 μm towards the core layer greatly improves air circulation efficiency, allowing for more thorough gas exchange between the leather's interior and the outside environment. This quickly removes moisture and odors from inside the leather, keeping it dry and fresh, further enhancing user comfort.

[0035] The leather body 1 has an edging 102 at its edge. The edging 102 acts as an additional protective layer, bearing some of the external force when the leather edge collides or rubs against other objects, reducing direct impact and wear on the edge. It prevents fiber breakage and pilling at the leather edge, maintaining its neatness and smoothness, and avoiding damage to the overall leather structure due to edge damage. This effectively extends the leather's lifespan and enhances its overall appearance and quality.

[0036] The buffer block 106 is made of a porous elastic material. It is physically locked to the upper leather blank 104 and the lower leather blank 107. This porous elastic material provides excellent elasticity and cushioning performance. When the leather is subjected to external impact, it can absorb and disperse energy through deformation, effectively cushioning the leather body 1 and protecting it from excessive damage. Furthermore, the physical locking method eliminates the need for additional chemical adhesives, making it more environmentally friendly and healthier. This connection method is also strong and reliable, preventing loosening and ensuring a tight bond between the buffer block 106 and the leather body 1, maintaining stable cushioning performance over long-term use.

[0037] Example 3: To further improve the durability and abrasion resistance of leather, for example, such as Figures 1 to 3 As shown, this utility model also includes: The wear-resistant protrusions 2 are made of wear-resistant polymer. They are fixed to the intersections of the buffer unit 101 via adhesive bonding or molding. Made of wear-resistant polymer, these protrusions 2 possess high hardness and wear resistance. When the leather rubs against other surfaces, the protrusions 2 are the first to bear the frictional force, effectively resisting wear and protecting the underlying buffer unit 101 and the leather body 1 from excessive wear. Fixed to the intersections of the buffer unit 101 via adhesive bonding or molding, their precise positioning and firm fixation ensure long-term wear resistance, reducing damage to the leather caused by frequent friction, extending the leather's lifespan, and improving its durability.

[0038] Example 4: To ensure the stability of the leather structure and the reliability of the connection, for example, such as Figures 1 to 3 As shown, this utility model also includes: The suture thread is made of high-strength fiber, and the diameter of the thread hole 103 matches the suture thread to ensure a tight connection between the upper leather base 104 and the lower leather base 107. The high-strength fiber thread has excellent tensile strength and abrasion resistance, capable of withstanding significant external forces without easily breaking. The matching diameter of the thread hole 103 allows the suture thread to pass tightly through the thread hole 103, ensuring a strong and reliable connection between the upper leather base 104 and the lower leather base 107. This matching design allows the suture thread to fully utilize its strength advantage, tightly binding the upper leather base 104 and the lower leather base 107 together, effectively preventing problems such as delamination and cracking of the leather during use due to weak connections, and improving the overall structural stability and durability of the leather.

[0039] Working principle: This high-quality cowhide consists of a leather body comprised of an upper hide and a lower hide. The grain layer of both the upper and lower hides extends downwards to form barbed collagen fibers, a characteristic of the leather's inherent structure. Multiple hexagonal array holes are perforated through the upper and lower hides, evenly dividing the leather body into multiple buffer units. The diameter of these holes matches the high-strength fiber thread (stitching thread), which passes through the holes to tightly connect and secure the upper and lower hides together. The working principle is that the hexagonal array of holes and matching stitching thread not only ensures a strong connection but also evenly distributes stress when the leather is under pressure, improving the overall stability and durability of the leather.

[0040] Each cushioning unit is filled with a cushioning block made of porous elastic material. The barbed collagen fibers of the upper and lower leather blanks are embedded in the fiber gaps of the cushioning block, forming a physical lock that firmly fixes the cushioning block to the upper and lower leather blanks. The porous elastic material of the cushioning block has excellent elasticity and cushioning performance. When the leather is subjected to external impact, the cushioning block can absorb and disperse energy through its own deformation, thus cushioning the leather and protecting it from excessive damage. Ventilation holes are perforated throughout the cushioning block. These holes are funnel-shaped with a gradually increasing pore size; the surface pores are 2-3 μm in diameter, gradually increasing to 8-10 μm towards the core. The working principle of this gradually increasing pore structure is that the smaller pore size at the surface effectively blocks larger particles such as dust from entering, while the gradually increasing pore size towards the core facilitates air circulation, allowing for good gas exchange between the leather's interior and the outside environment, maintaining the leather's breathability and improving comfort during use.

[0041] An edging is installed along the edges of the leather body to protect the edges, prevent wear and cracking, and extend the leather's lifespan. Abrasion-resistant bumps are placed at the intersection of two adjacent cushioning units. These bumps, made of abrasion-resistant polymer, are fixed to the intersection by adhesive or molding and are higher than the cushioning units. When the leather rubs against other objects, the abrasion-resistant bumps bear the friction force first. Due to their excellent abrasion resistance, they effectively reduce overall wear on the leather, protecting both the cushioning units and the leather body.
