Description

Technical Field

[0001] The utility model relates to the technical field of microfiber leather, in particular to a microfiber leather with good air permeability. Background Art

[0002] Microfiber synthetic leather is referred to as microfiber leather. It is based on sea-island fiber non-woven fabric, which is impregnated with polyurethane slurry and formed into sea-island fiber / polyurethane composite material after wet coagulation. It has become an ideal material to replace natural leather. The biggest difference between the microfiber leather process and the wet synthetic leather process is that the fiber is opened after impregnation and coagulation to turn the sea-island fiber into microfiber. Since the fiber of microfiber leather is very fine, it is closer to natural leather in terms of microstructure and performance, and has better mechanical properties.

[0003] As a new type of artificial leather, microfiber leather has excellent properties such as soft texture, wear resistance, and folding resistance, but its moisture permeability is insufficient. When the human body sweats, the moisture permeability of fiber leather is poor. The high humidity environment formed by the evaporation of sweat cannot be discharged through the leather in time, causing the wearer to feel stuffy and uncomfortable, and causing sweat and moisture to remain in the space between the leather and the body for a long time, which is easy to breed bacteria. Microfiber leather can easily damage the color of the leather and cause it to fade if used for a long time or exposed to sunlight. Utility Model Content

[0004] The utility model provides a microfiber leather with good breathability. By sequentially arranging a porous polyurethane layer, a moisture-permeable layer and a breathable fabric layer on a microfiber base cloth, the microfiber leather can have excellent moisture permeability and breathability, thereby improving wearing comfort and health, and avoiding the poor moisture permeability of fiber leather, in which the high humidity environment formed by sweat evaporation cannot be discharged through the leather in time, causing the wearer to feel stuffy and uncomfortable, and easily breeding bacteria. The anti-fading layer can effectively prevent external factors such as ultraviolet rays and chemicals from damaging the color of the leather, so that the leather has long-term color stability and is not easy to fade even after long-term use or exposure to sunlight.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solutions: A microfiber leather with good air permeability, comprising:

[0006] Microfiber base fabric;

[0012] Furthermore, the material of the breathable fabric layer is a highly breathable mesh.

[0013] Furthermore, the anti-fading layer is fixedly arranged on the top of the outer wall of the breathable fabric layer.

[0014] The utility model provides a microfiber leather with good air permeability, which has the following beneficial effects:

[0015] (1) The microfiber leather with good breathability can provide the microfiber leather with excellent moisture permeability and breathability by sequentially arranging a porous polyurethane layer, a moisture permeable layer and a breathable fabric layer on a microfiber base cloth, thereby improving wearing comfort and health, and avoiding the poor moisture permeability of fiber leather, in which the high humidity environment formed by the evaporation of sweat cannot be discharged through the leather in time, causing the wearer to feel stuffy and uncomfortable, and easily breeding bacteria.

[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of them. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts are within the scope of protection of the present invention.

[0022] See also Figure 1-3 The utility model provides a technical solution: a microfiber leather with good air permeability, comprising:

[0023] Microfiber base cloth 1;

[0024] A moisture permeable mechanism is provided on the microfiber base fabric 1, and the moisture permeable mechanism includes a porous polyurethane layer 2 and a moisture permeable component. The porous polyurethane layer 2 is fixedly provided on one side of the outer wall of the microfiber base fabric 1, and the moisture permeable component is provided on the porous polyurethane layer 2;

[0025] The anti-fading layer 3 is provided on the moisture-permeable component.

[0026] In this embodiment: the microfiber base cloth 1 serves as a substrate, which can provide the necessary physical strength and flexibility. Through the moisture-permeable mechanism, the air permeability and moisture permeability of the microfiber leather can be increased, thereby avoiding the poor moisture permeability of the microfiber leather. The high humidity environment formed by the evaporation of sweat cannot be discharged through the leather in time, causing the wearer to feel stuffy and uncomfortable, and easily breeding bacteria. Through the porous polyurethane layer 2, good moisture permeability can be achieved. Through the moisture-permeable component, the moisture permeability of the microfiber leather can be further improved. Through the anti-fading layer 3, it can effectively prevent external factors such as ultraviolet rays and chemicals from damaging the color of the leather.

[0027] Specifically, a plurality of air holes 4 are equidistantly formed on the top of the outer wall of the porous polyurethane layer 2 .

[0028] In this embodiment: laser drilling technology is used on the surface of the porous polyurethane layer 2 to form evenly distributed tiny air pores 4. These air pores 4 serve as additional ventilation channels to further improve the moisture permeability of the leather. The porous polyurethane layer 2 is coated on the microfiber base cloth 1 and is cured and formed by heating.

[0029] Specifically, the moisture permeable component includes a moisture permeable layer 5 and a breathable fabric layer 6 . The moisture permeable layer 5 is fixedly arranged on the top of the outer wall of the porous polyurethane layer 2 , and the breathable fabric layer 6 is fixedly arranged on the top of the outer wall of the moisture permeable layer 5 .

[0030] In this embodiment, the moisture permeability of the microfiber leather can be further improved by the moisture permeable layer 5 and the breathable fabric layer 6.

[0031] Specifically, the material of the moisture-permeable layer 5 is a PTFE microporous film.

[0032] In this embodiment, the PTFE microporous film is laminated on the porous polyurethane layer 2, which can maintain the softness and wear resistance of the microfiber leather and increase the moisture permeability.

[0033] Specifically, the material of the breathable fabric layer 6 is a highly breathable mesh.

[0034] In this embodiment, a highly breathable mesh with good air permeability is composited on the moisture permeable layer 5 by heat pressing, which further enhances the air permeability of the leather and provides richer tactile and visual effects.

[0035] Specifically, the anti-fading layer 3 is fixedly arranged on the top of the outer wall of the breathable fabric layer 6 .

[0036] In this embodiment: the anti-fading layer 3 is formed by treating the leather with an anti-fading treatment agent to form a protective film on the surface of the leather, which effectively prevents external factors such as ultraviolet rays and chemicals from damaging the color of the leather, so that the leather has long-term color stability and is not easy to fade even after long-term use or exposure to sunlight.

[0037] During use, by sequentially arranging a porous polyurethane layer 2, a moisture-permeable layer 5 and a breathable fabric layer 6 on the microfiber base cloth 1, the microfiber leather can have excellent moisture permeability and breathability, which can improve wearing comfort and health, and avoid the poor moisture permeability of the fiber leather. The high humidity environment formed by the evaporation of sweat cannot be discharged through the leather in time, which will cause the wearer to feel stuffy and uncomfortable and easily breed bacteria. The anti-fading layer 3 can effectively prevent external factors such as ultraviolet rays and chemicals from damaging the color of the leather, so that the leather has long-term color stability and is not easy to fade even after long-term use or exposure to sunlight.

[0038] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
