[0005] To achieve the above purpose, the utility model provides the following technical scheme: a solvent-resistant leather, which includes a base cloth layer, a foaming layer and a genuine leather layer from top to bottom. A solvent-resistant layer is provided on the surface of the genuine leather layer. A number of concave strips are formed by bending the base cloth layer downward at equal intervals. A number of grooves matching with the respective concave strips are opened on the upper surface of the foaming layer. Each concave strip is attached to the inner wall of the corresponding groove. The genuine leather layer and the foaming layer are bonded by a water-based glue.

[0006] Further, a number of wear-resistant strips are arranged on the surface of the non-bent part of the genuine leather layer at equal intervals, and the wear-resistant strips are arranged horizontally and obliquely.

[0007] Further, a number of slot holes are also opened on the upper surface of the foaming layer, and the slot holes are filled with water-based glue.

[0008] Further, the solvent-resistant layer is vinyl resin, and the vinyl resin is coated on the surface of the genuine leather layer.

[0009] Further, the base cloth layer is a superfine fiber cloth.

[0010] Compared with the prior art, the beneficial effects of the utility model are:

[0011] The utility model has a novel structure and reasonable design. Through the solvent-resistant layer provided on the surface of the genuine leather layer, an effective solvent-resistant effect is achieved. Under the action of the wear-resistant strips thereon, the leather has excellent wear resistance and hydrophobicity, and a tight and stable connection structure is formed between the genuine leather layer and the foaming layer through the bending structure design, so as to have the effects of comfortable use and strong functionality.

[0016] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0017] As Figure 1 , Figure 2 and Figure 3 shown, a solvent-resistant leather includes a base fabric layer 1, a foaming layer 2, and a true leather layer 3 from top to bottom. A solvent-resistant layer is provided on the surface of the true leather layer 3. A plurality of recessed strips 4 are formed by bending the base fabric layer 1 downward at equal intervals. A plurality of grooves 5 matching the respective recessed strips 4 are formed on the upper surface of the foaming layer 2. The inner walls of the respective recessed strips 4 are attached to the inner walls of the corresponding grooves 5. The true leather layer 3 and the foaming layer 2 are bonded by an aqueous adhesive.

[0018] In this embodiment, a plurality of wear-resistant strips 6 are provided at equal intervals on the surface of the non-bent part of the true leather layer 3, and the wear-resistant strips 6 are arranged horizontally and obliquely.

[0019] In this embodiment, a plurality of slot holes 7 are further formed on the upper surface of the foaming layer 2, and the slot holes 7 are filled with an aqueous adhesive.

[0020] In this embodiment, the solvent-resistant layer is vinyl resin, and the vinyl resin is coated on the surface of the true leather layer 3.

[0021] In this embodiment, the base fabric layer 1 is a superfine fiber cloth. The superfine fiber has high folding fastness and can reach 200,000 times of bending without cracks at room temperature, which can further improve the tear resistance of the leather.

[0022] The working principle of this embodiment is as follows:

[0023] The leather surface is provided with a vinyl resin layer, which plays an effective role in solvent resistance. The wear-resistant strip 6 thereon can also enhance the wear resistance of the surface. At the same time, the inclined wear-resistant strip 6 can quickly introduce the liquid onto the upper surface of the recessed strip 4, and then flow out from the leather surface through the recessed strip 4, reducing the residence time of the liquid on the dermis layer 3.

[0024] The curved recesses on the dermis layer 3 fit with the grooves 5 on the foaming layer 2, and the connection strength is improved by increasing the contact area. The setting of the recesses can also improve the tensile and anti-deformation abilities of the dermis layer 3. By setting the water-based glue overflowing from the slot holes 7, the connection strength between the dermis layer 3 and the foaming layer 2 can be further improved, forming a tight and stable connection structure between layers, solving the problems that the fiber structure of the existing leather may cause a decrease in strength due to solvent erosion, or is prone to deformation in high-temperature and high-humidity environments, thus affecting durability and comfort.

[0025] 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 perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
