Description

Technical Field

[0001] This utility model relates to the field of leather, and more particularly to an odor-adjustable leather. Background Technology

[0002] As a modern means of transportation, the automobile has undergone a long and profound transformation since its inception. From its initial simple mechanical structure that could only meet basic travel needs, it has evolved into a complex transportation tool that integrates high technology, comfort, safety, and aesthetics. Today, with the global car ownership continuing to rise, the automobile is no longer just a means of transportation, but has become a symbol of people's quality of life. Among them, the car interior is the part that drivers and passengers directly come into contact with and can intuitively feel. Its design and quality have a crucial impact on the overall user experience of the car. Car leather is an important component of the car interior, which not only affects the car's aesthetics and sense of luxury, but also plays a key role in ride comfort and durability.

[0003] Existing automotive leather has a relatively limited function, mostly improving passenger comfort. However, during car use, a lot of odors may be generated inside the car, such as sweat, food smells, and smoke. Existing automotive leather is difficult to absorb and treat these odors, making it difficult to create a fresh environment inside the car. This can easily reduce the comfort of passengers and reduce the practicality of automotive leather. Summary of the Invention

[0004] Therefore, in order to overcome the above-mentioned shortcomings, this utility model provides an odor-adjustable leather to solve the above-mentioned technical problems.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an odor-adjustable leather, comprising a bottom layer, a buffer layer, a spandex fiber fabric layer, a surface layer, hydrogel particles, and plant tannins. The buffer layer is disposed on the bottom layer, the spandex fiber fabric layer is connected to the top surface of the buffer layer, and a microporous polyurethane film is disposed between the spandex fiber fabric layer and the buffer layer. The surface layer is connected to the upper surface of the spandex fiber fabric layer.

[0006] The spandex fiber fabric layer is woven from several warp and several weft threads, and several pores are formed between adjacent warp and adjacent weft threads. The pores are filled with hydrogel particles, and plant tannins are placed in the hydrogel particles.

[0007] Preferably, the surface layer is provided with anti-slip texture.

[0008] Preferably, the upper surface of the surface layer is coated with a protective coating that completely covers the anti-slip texture.

[0009] Preferably, the upper surface of the spandex fiber fabric layer is coated with a reinforcing coating, which is made of nano-silica material.

[0010] Preferably, the surface layer is made of natural leather.

[0011] The beneficial effects of this utility model are:

[0012] This invention incorporates hydrogel particles and plant tannins. Plant tannins, as natural antibacterial and antioxidant agents, can effectively absorb and neutralize odors in automobiles. Furthermore, the hydrogel particles regulate the release rate of plant tannin gases, making the odor-regulating effect long-lasting and controllable. This helps maintain fresh air inside the vehicle, improves passenger comfort, and enhances the practicality of automotive leather. Attached Figure Description

[0015] Figure 3 This is a top view schematic diagram of the spandex fiber fabric layer of this utility model.

[0016] The layers are: bottom layer-1, buffer layer-2, spandex fiber fabric layer-3, surface layer-4, anti-slip texture-5, protective coating-6, hydrogel particles-7, plant tannin-8, reinforcing coating-9, microporous polyurethane film-10, warp-31, and weft-32. Detailed Implementation

[0017] To further explain the technical solution of this utility model, a detailed description is provided below through specific embodiments.

[0018] like Figure 1 As shown, this utility model provides an odor-adjustable leather, including a bottom layer 1;

[0019] like Figures 1 to 3 As shown, this embodiment also includes a buffer layer 2, a spandex fiber fabric layer 3, a surface layer 4, hydrogel particles 7, and plant tannins 8. The buffer layer 2 is connected to the upper surface of the bottom layer 1. In this embodiment, the buffer layer 2 is made of high-elasticity foam, which improves the comfort of the leather and is beneficial to improving the comfort of car passengers.

[0020] A spandex fiber fabric layer 3 is pasted and fixed to the top surface of the buffer layer 2, and a microporous polyurethane film 10 is pasted between the spandex fiber fabric layer 3 and the buffer layer 2. The surface layer 4 is connected and fixed to the upper surface of the spandex fiber fabric layer 3.

[0021] The spandex fiber fabric layer 3 is woven from several crisscrossing warp threads 31 and weft threads 32, and several pores are formed between adjacent warp threads 31 and adjacent weft threads 32. The pores are filled with hydrogel particles 7, and plant tannins 8 are placed in the hydrogel particles 7. The plant tannins 8 are taratannins, which have certain antibacterial properties and can inhibit the growth of bacteria on the leather surface, reduce odors caused by bacterial growth, and thus regulate the smell inside the car to a certain extent.

[0022] In this embodiment, the surface layer 4 is provided with anti-slip texture 5. The anti-slip texture 5 not only helps to improve the appearance of the leather, but also increases the friction of the leather surface to a certain extent, preventing the passenger from sliding on the seat cushion.

[0023] In this embodiment, the upper surface of the surface layer 4 is coated with a protective coating 6, which completely covers the anti-slip texture 5. In this embodiment, the protective coating 6 is a transparent water-based acrylic coating, which can provide the leather with good wear resistance, water resistance and stain resistance, and it is breathable, which helps to release the odor of plant tannins.

[0024] In this embodiment, the upper surface of the spandex fiber fabric layer 3 is coated with a reinforcing coating 9, which is made of nano-silica material. This coating improves the sealing performance of the spandex fiber fabric layer 3 and reduces the leakage of hydrogel particles 7. At the same time, the nano-silica has good breathability, and the plant tannin odor can still be released well.

[0025] In this embodiment, the surface layer 4 is made of natural leather, providing a soft feel and a high-end appearance;

[0026] Specifically, when in use, the scent emitted by plant tannin 8 is used to regulate the odor inside the car, reducing unpleasant smells and improving the comfort of passengers. Furthermore, the release rate of plant tannin 8 is controlled by the hydrogel particles 7, which helps to extend the lifespan of plant tannin 8.

[0027] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
