Description

Technical Field

[0001] The utility model relates to the field of textile materials, in particular to artificial breathable leather. Background Art

[0002] Artificial leather is made of foamed or laminated PVC and PU with various formulations on a textile or non-woven base. It can be processed according to different strength, color, gloss, pattern and other requirements.

[0003] However, most leather materials have poor air permeability, especially when used as shoe production materials, which can easily cause stuffiness inside the shoes. Utility Model Content

[0004] In order to reduce the situation where leather shoes become stuffy due to poor air permeability of leather, the present application provides an artificial breathable leather.

[0005] The artificial breathable leather provided in this application adopts the following technical solution:

[0006] An artificial breathable leather is characterized in that it includes a leather layer, a base fabric layer, an antibacterial layer and a cooling silk layer arranged in sequence from the outside to the inside, the leather layer is evenly provided with a plurality of micro-breathable holes, the base fabric layer, the antibacterial layer and the cooling silk layer are evenly provided with a plurality of completely penetrating holes, the holes on the base fabric layer, the antibacterial layer and the cooling silk layer cooperate to form a cavity, and the cavity is spherical; the plurality of cavities are connected one-to-one with the plurality of micro-breathable holes.

[0007] Through the above technical solution, when the wearer walks, the cavity will be continuously squeezed, and the squeezed cavity will force the air in the cavity to be squeezed out through the connected micro-vents; and when the cavity recovers, the air will be sucked in through the micro-vents, thereby accelerating the air circulation efficiency, enhancing the breathability, and reducing the stuffiness inside the leather shoes.

[0008] Preferably, a plurality of hollow thin cylinders are further included, and the outer circumferences of the plurality of hollow thin cylinders are bonded and fixed one-to-one to the inner walls of the plurality of micro air holes.

[0009] Through the above technical solution, after multiple ventilation holes are opened in the leather, the tensile performance of the leather will be reduced; and the setting of the hollow thin tube enhances the tensile strength at the opening position, thereby reducing deformation and tearing at the opening position when stretched, thereby extending the service life of the leather.

[0010] Preferably, a tensile layer is further included, which is located between the base fabric layer and the antibacterial layer. The tensile layer includes multiple elastic yarns, which are woven along the warp and weft to form a tensile grid, and the cavity is located in the mesh of the tensile grid.

[0011] Through the above technical solution, ventilation holes are opened in the mesh of the tensile grid to avoid cutting off the elastic yarn. The elastic yarn can limit excessive bending of the leather and quickly restore it after bending through its own elastic force, reducing the deformation and tearing of the leather at the opening position when it is stretched, thereby enhancing the tensile properties of the leather.

[0012] Preferably, the tensile grid comprises a plurality of elastic strips, and the elastic strips are spirally wound and fixed on a plurality of elastic yarns in a one-to-one manner.

[0013] Through the above technical solution, the elastic strip increases the strength of the elastic yarn against torsional force, thereby enhancing the bending performance of the leather.

[0014] Preferably, the leather layer is made of PU material.

[0015] Through the above technical solution, PU leather is a synthetic material composed of a polyurethane coating and a base fabric. It has good softness, delicate hand feel, high simulation degree, and can simulate the texture of natural leather. It also has good wear resistance and water resistance, is not easy to be damaged or scratched, is not easy to be affected by moisture, has a long service life, is easy to clean and maintain, and has the advantages of relatively low price.

[0016] Preferably, the base fabric layer is woven by warp and weft yarns to form a plain weave.

[0017] Through the above technical solution, the plain weave has the characteristic of structural stability, which ensures the stability of the base fabric layer structure.

[0018] Preferably, the antibacterial layer is made of bamboo fiber fabric and coated with nano silver ion coating.

[0019] Through the above technical solution, bamboo fiber has excellent air permeability due to its unique microporous structure and surface properties, and can effectively adsorb and inhibit the growth of microorganisms such as bacteria and mold; at the same time, the nano silver ion coating has a strong bactericidal ability, and it will not be consumed during the antibacterial process, and can maintain its effect for a long time, and the nano silver ion coating is non-toxic and harmless to the human body.

[0020] Preferably, the cool silk layer is made of cool fabric.

[0021] Through the above technical solution, the cool fabric is woven from cool fibers, and because the cool fibers contain inorganic powder, the heat absorption rate will be slowed down and the heat dissipation rate will be accelerated. The slow heat absorption and fast heat dissipation characteristics of the cool fibers will increase the coolness when they come into contact with the human body, thereby reducing the stuffy feeling inside the leather shoes from a physical sense.

[0022] The technical effects of this utility model are mainly reflected in the following aspects:

[0023] 1. The utility model opens ventilation holes and cavities, which speed up the air circulation efficiency during the extrusion and deformation of the cavity, enhances the breathability, and reduces the stuffiness in the leather shoes;

[0024] 2. The utility model increases the tensile strength at the opening position by setting a hollow thin tube in the vent hole, thereby reducing the deformation and tearing at the opening position when stretched, thereby extending the service life of the leather;

[0025] 3. The utility model provides a tensile layer to reduce deformation and tearing of the leather at the opening position when stretched, thereby enhancing the tensile performance of the leather. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] The following is combined with Figure 1-2 , the specific implementation methods of the utility model are further described in detail to make the technical solution of the utility model easier to understand and grasp.

[0030] The present application discloses an artificial breathable leather:

[0031] Reference Figure 1 A man-made breathable leather comprises a leather layer 1, a base fabric layer 2, an antibacterial layer 3, and a cool-weave layer 4, all sewn together from the outside inward. The leather layer 1 is uniformly provided with a plurality of micro-breathing holes 11, while the base fabric layer 2, the antibacterial layer 3, and the cool-weave layer 4 are uniformly provided with a plurality of completely penetrating holes. The holes in the base fabric layer 2, the antibacterial layer 3, and the cool-weave layer 4 cooperate to form a spherical cavity 5. The cavities 5 are connected one-to-one with the micro-breathing holes 11. When the wearer walks, the cavities 5 are continuously squeezed, and the squeezed cavities 5 force the air inside the cavities 5 outward through the connected micro-breathing holes 11. When the cavities 5 recover, they draw air back in through the micro-breathing holes 11, thereby increasing air circulation efficiency, enhancing breathability, and reducing stuffiness inside the leather shoe. Furthermore, the multi-layer structure around the outer edges of the cavities 5 should be reinforced with needlework to prevent delamination caused by repeated squeezing of the cavities 5 during daily walking.

[0032] Reference Figure 1The leather is also provided with a plurality of hollow thin tubes 6, the outer circumferences of which are bonded one-to-one to the inner walls of the plurality of micro-breathing holes 11. Since the leather's tensile strength is reduced after the plurality of breather holes 11 are formed, the provision of the hollow thin tubes 6 enhances the tensile strength at the openings, thereby reducing deformation and tearing at the openings during stretching and extending the leather's service life.

[0033] Reference Figure 1-2 The leather fabric also includes a tensile layer 7 positioned between the base fabric layer 2 and the antibacterial layer 3. The tensile layer 7 comprises a plurality of elastic yarns 71 woven along the warp and weft to form a tensile mesh 72. The cavity 5 is located within the meshes of the tensile mesh 72. The elastic yarns 71 are secured to the antibacterial layer 3 by sewing. Breathing holes 11 are defined within the meshes of the tensile mesh 72 to prevent the elastic yarns 71 from being cut. The elastic force of the elastic yarns 71 prevents excessive bending of the leather and allows it to quickly return to its original position after bending. This reduces deformation and tearing of the leather at the openings when stretched, thereby enhancing the leather's tensile properties.

[0034] The tensile grid 72 further includes a plurality of elastic strips 73, which are spirally wound one-to-one and fixed on the plurality of elastic yarns 71. The elastic strips 73 increase the strength of the elastic yarns 71 against torsional forces, thereby enhancing the bending performance of the leather.

[0035] Reference Figure 1 The leather layer 1 is made of PU material. PU leather is a synthetic material consisting of a polyurethane coating and a base fabric. It has good softness, a delicate feel, a high degree of simulation, and can simulate the texture of natural leather. It also has good wear resistance and water resistance, is not easily damaged or scratched, is not easily affected by moisture, has a long service life, is easy to clean and maintain, and has the advantages of being relatively inexpensive.

[0036] Reference Figure 1 The base fabric layer 2 is woven with yarns in warp and weft to form a plain weave. The plain weave has the characteristic of stable structure, which ensures the stability of the structure of the base fabric layer 2.

[0037] Reference Figure 1 The antibacterial layer 3 is made of bamboo fiber and coated with a nano-silver ion coating. Bamboo fiber, due to its unique microporous structure and surface properties, has excellent air permeability and can effectively absorb and inhibit the growth of microorganisms such as bacteria and mold. The nano-silver ion coating also has a strong bactericidal ability and is not consumed during the antibacterial process, maintaining its effect over time. Furthermore, the nano-silver ion coating is non-toxic and harmless to the human body.

[0038] Reference Figure 1The cooling layer 4 is made of a cool fabric. The cool fabric is woven from cool fibers. Because the cool fibers contain inorganic powder, their heat absorption rate slows down while their heat dissipation rate accelerates. This slow heat absorption and fast heat dissipation property of the cool fibers increases the coolness when in contact with the human body, thereby reducing the feeling of stuffiness inside the leather shoes.

[0039] Of course, the above are only typical examples of the present invention. In addition, the present invention may have many other specific implementation methods. Any technical solution formed by equivalent replacement or equivalent transformation falls within the scope of protection required by the present invention.
