Description

Technical Field

[0001] This utility model relates to the field of artificial fabric technology, specifically a type of technological leather with a wear-resistant structure. Background Technology

[0002] Technical leather is a type of artificial leather. By applying a PU or PVC coating to a non-woven fabric base, it closely resembles genuine leather in color, appearance, and feel, and is cheaper than genuine leather. It has a wide range of applications in furniture, automotive supplies, clothing, and other fields.

[0003] Most commercially available tech leathers are similar in overall structure, using non-woven or microfiber fabric as a base, with a PU coating bonded to the base fabric using adhesive. They have a soft feel, but in actual use, they have some functional shortcomings and room for improvement. For example, the coating is different from animal protein fibers, and its physical properties are slightly inferior. Furthermore, due to the single coating structure, its wear resistance is poor, and it is prone to cracking and peeling over time, lacking the function of a coating to enhance wear resistance.

[0004] Now, a new type of technological leather with a wear-resistant structure is proposed to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a technological leather with a wear-resistant structure to solve the problem mentioned in the background art of not having the function of coating to enhance wear resistance.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a wear-resistant technological leather, comprising a non-woven fabric base layer, a PU simulated leather layer disposed above the non-woven fabric base layer, an adhesive layer disposed between the non-woven fabric base layer and the PU simulated leather layer, an upper foam layer disposed below the non-woven fabric base layer, an upper microfiber mesh surface adhered to the top of the upper foam layer, a lower foam layer disposed at the bottom of the upper foam layer, a lower microfiber mesh surface disposed at the bottom of the lower foam layer, multiple sets of peppermint extract powder particles filled between the upper and lower foam layers, and an anti-cracking component disposed inside the PU simulated leather layer to improve wear resistance.

[0007] The anti-cracking component includes a bottom microfiber mesh, which is disposed at the bottom end of the PU simulated leather layer. Multiple sets of bottom microfiber fibers are glued to the bottom end of the bottom microfiber mesh. A top microfiber mesh is disposed above the bottom microfiber mesh. Multiple sets of connecting filaments are glued between the bottom microfiber mesh and the top microfiber mesh. Multiple sets of top microfiber fibers are disposed at the top end of the top microfiber mesh.

[0008] As a further technical solution of this utility model, the bottom end of the bottom microfiber mesh is connected to the top end of the adhesive layer, and the bottom microfiber fibers penetrate the adhesive layer and extend into its interior.

[0009] As a further technical solution of this utility model, the bottom microfiber mesh, the connecting wire, and the top microfiber mesh are made of the same material, and the connecting wire is arranged at equal intervals.

[0010] As a further technical solution of this utility model, the top tip of the top microfiber hair is lower than the bottom end of the PU pseudo-skin layer, and the PU pseudo-skin layer completely covers the bottom microfiber mesh, connecting filaments, top microfiber mesh, and top microfiber hair.

[0011] As a further technical solution of this utility model, the upper foam layer and the lower foam layer have the same thickness, and the upper foam layer and the lower foam layer are bonded together by an adhesive.

[0012] As a further technical solution of this utility model, the upper microfiber mesh and the lower microfiber mesh have the same specifications, and the top end of the upper microfiber mesh and the bottom end of the nonwoven fabric base are bonded together by an adhesive.

[0013] As a further technical solution of this utility model, the lower foam layer and the lower microfiber mesh are bonded together by an adhesive, and the upper foam layer and the lower foam layer are elastic.

[0014] As a further technical solution of this utility model, the upper foaming layer and the lower foaming layer have fine pores inside, and the outer diameter of the peppermint extract powder particles is larger than the pore diameter of the pores on the inner surface of the upper foaming layer and the lower foaming layer.

[0015] Compared with the prior art, the beneficial effects of this utility model are: the wear-resistant leather not only achieves the function of coating to enhance wear resistance, but also achieves the function of thickening the bottom to improve support, and also achieves the function of preventing cats from scratching.

[0016] By setting up a PU simulated leather layer, a bottom microfiber mesh, bottom microfiber fibers, connecting filaments, a top microfiber mesh, and top microfiber fibers, the non-woven fabric base layer serves as the base for the technological leather. The PU simulated leather layer is bonded to its surface through an adhesive layer. The PU simulated leather layer adopts an internally reinforced support structure. The flexible skeleton formed by the bottom microfiber mesh, connecting filaments, and top microfiber mesh can increase the structural strength of the PU simulated leather layer. The top microfiber fibers extend upwards and pull the surface of the PU simulated leather layer, making it less prone to cracking when folded. When bent, the surface exhibits a wider curvature, making it more wear-resistant and less likely to be worn through. The bottom microfiber fibers increase the tightness of the connection with the adhesive layer, making it less prone to delamination and peeling, thus achieving the function of coating-enhanced wear resistance.

[0017] By setting up an upper microfiber mesh, an upper foam layer, a lower foam layer, and a lower microfiber mesh, the bottom of the nonwoven fabric base layer is thickened. The upper and lower foam layers are covered and supported by the upper and lower microfiber mesh, respectively, providing support for the leather material as a whole, making it thicker and softer, with better support, thus achieving the function of thickening the bottom to improve support.

[0018] By incorporating an upper foam layer, a lower foam layer, and peppermint extract powder, the peppermint extract powder filling the space between the upper and lower foam layers slowly releases its aroma, which is difficult for humans to detect. However, it is highly stimulating to cats with a sensitive sense of smell, causing them to stay away and preventing them from scratching or using the product for clawing. Attached Figure Description

[0024] 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.

[0025] Example: Please refer to Figure 1-4A type of wear-resistant leather includes a non-woven base layer 1, a PU simulated leather layer 3 on top of the non-woven base layer 1, an adhesive layer 2 between the non-woven base layer 1 and the PU simulated leather layer 3, an upper foam layer 10 below the non-woven base layer 1, an upper microfiber mesh 9 bonded to the top of the upper foam layer 10, a lower foam layer 11 at the bottom of the upper foam layer 10, a lower microfiber mesh 12 at the bottom of the lower foam layer 11, multiple sets of peppermint extract powder particles 13 filled between the upper foam layer 10 and the lower foam layer 11, and an anti-cracking component that can improve wear resistance is provided inside the PU simulated leather layer 3.

[0026] Please see Figure 1-4 A type of technological leather with a wear-resistant structure also includes an anti-cracking component. The anti-cracking component includes a bottom microfiber mesh 4, which is disposed at the bottom end of the PU simulated leather layer 3. Multiple sets of bottom microfiber hairs 5 are glued to the bottom end of the bottom microfiber mesh 4. A top microfiber mesh 7 is disposed above the bottom microfiber mesh 4. Multiple sets of connecting wires 6 are glued between the bottom microfiber mesh 4 and the top microfiber mesh 7. Multiple sets of top microfiber hairs 8 are disposed at the top end of the top microfiber mesh 7.

[0027] The bottom end of the bottom microfiber mesh 4 is connected to the top end of the adhesive layer 2. The bottom microfiber hairs 5 penetrate the adhesive layer 2 and extend into it. The bottom microfiber mesh 4, connecting wires 6, and top microfiber mesh 7 are made of the same material. The connecting wires 6 are arranged at equal intervals. The top end of the top microfiber hairs 8 is lower than the bottom end of the PU simulated leather layer 3. The PU simulated leather layer 3 completely covers the bottom microfiber mesh 4, connecting wires 6, top microfiber mesh 7, and top microfiber hairs 8, increasing the structural strength of the coating and improving its wear resistance.

[0028] Specifically, such as Figure 1 and Figure 2 As shown, the PU simulated skin layer 3 has an internal support structure. The flexible skeleton composed of the bottom microfiber mesh 4, connecting filaments 6, and top microfiber mesh 7 can increase the structural strength of the PU simulated skin layer 3. The top microfiber hairs 8 extend upward to pull the surface of the PU simulated skin layer 3, making it less prone to cracking when folded. The surface exhibits a wider curvature when bent, making it more wear-resistant. The bottom microfiber hairs 5 increase the tightness of the connection with the adhesive layer 2, making it less prone to delamination and peeling.

[0029] The upper foam layer 10 and the lower foam layer 11 have the same thickness. The upper foam layer 10 and the lower foam layer 11 are bonded together with an adhesive. The upper microfiber mesh surface 9 and the lower microfiber mesh surface 12 have the same specifications. The top of the upper microfiber mesh surface 9 and the bottom of the nonwoven base layer 1 are bonded together with an adhesive to increase the thickness and softness.

[0030] Specifically, such as Figure 1 and Figure 3As shown, the foamed layer consisting of the upper foamed layer 10 and the lower foamed layer 11 is covered and supported by the upper microfiber mesh 9 and the lower microfiber mesh 12, respectively, which provides support for the leather as a whole, making it thicker, softer, and more supportive.

[0031] The lower foam layer 11 and the lower microfiber mesh 12 are bonded together with an adhesive. The upper foam layer 10 and the lower foam layer 11 are elastic. The upper foam layer 10 and the lower foam layer 11 have fine pores inside. The outer diameter of the peppermint extract powder 13 is larger than the pore size of the pores on the inner surface of the upper foam layer 10 and the lower foam layer 11, which can prevent cats from scratching.

[0032] Specifically, such as Figure 1 and Figure 4 As shown, the peppermint extract powder 13 filled between the upper foam layer 10 and the lower foam layer 11 has a slow-evaporating aroma that slowly dissipates through the pores inside the upper foam layer 10 and the lower foam layer 11, which is more stimulating to cats with a sensitive sense of smell.

[0033] Working Principle: In use, this invention firstly uses a non-woven fabric base layer 1 as the base for the technological leather. A PU simulated leather layer 3 is bonded to its surface via an adhesive layer 2. The PU simulated leather layer 3 incorporates an internal support structure. A flexible skeleton composed of a bottom microfiber mesh 4, connecting filaments 6, and a top microfiber mesh 7 increases the structural strength of the PU simulated leather layer 3. The top microfiber fibers 8 extend upwards, pulling the surface of the PU simulated leather layer 3, making it less prone to cracking during folding and exhibiting a wider curvature when bent, thus increasing its wear resistance. The bottom microfiber fibers 5 increase the tightness of the connection with the adhesive layer 2, preventing delamination and peeling. The bottom of the non-woven fabric base layer 1 is thickened, and an upper microfiber mesh surface 9 and a lower microfiber mesh surface 12 cover and support the foamed layer composed of an upper foamed layer 10 and a lower foamed layer 11, respectively, providing overall support for the leather material, making it thicker, softer, and more supportive. The peppermint extract powder 13 filled between the upper foam layer 10 and the lower foam layer 11 has a slow-evaporating odor that slowly dissipates through the pores inside the upper foam layer 10 and the lower foam layer 11. It is difficult for humans to detect, but it is more stimulating to cats with a more sensitive sense of smell, keeping them away and preventing them from using it to scratch or sharpen their claws.

Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
