Description

Technical Field

By passing polyvinyl chloride and polyurethane polymer materials through a series of processing techniques, it has a leather-like texture, thus replacing natural leather in many fields. The production cost of artificial leather is lower than that of natural leather. The production of natural leather requires a complex and costly process of animal breeding and tanning. Artificial leather has great advantages in raw material costs and production efficiency through chemical synthesis and processing, and can provide consumers with more affordable products.

A first soft layer is disposed between the upper layer and the first foamed resin layer, and a second soft layer is disposed between the lower layer and the second foamed resin layer. The first and second soft layers are each provided with a plurality of fine pores, and both the upper and lower layers are provided with a plurality of fine pores.

Based on the embodiments in the utility model, all other embodiments obtained by the ordinary skill in the art without making creative labor belong to the range of the utility model protection.

[0039] Refer to Figure 1 , Figure 3 and Figure 4, the utility model provides an embodiment: rubbing and friction resistant artificial leather, including a base fabric layer 1, the top wall of the base fabric layer 1 is fixedly connected with an anti-tear layer 3, under the action of the anti-tear layer 3, the tearing effect of the artificial leather is improved, and the rubbing resistance effect is increased, the inner bottom wall of the anti-tear layer 3 is fixedly connected with a woven mesh 4, the top wall of the woven mesh 4 is fixedly connected with a polyurethane resin reinforcement rib 5, the inner wall of the polyurethane resin reinforcement rib 5 is fixedly connected with a plurality of high-strength fibers 6, under the connection between the polyurethane resin reinforcement rib 5 and the high-strength fiber 6, the connection strength inside the anti-tear layer 3 is improved, the top wall of the high-strength fiber 6 is fixedly connected with a polyvinyl chloride connecting rib 7, the inner wall of the polyvinyl chloride connecting rib 7 is equidistantly fixed with a plurality of synthetic fibers 8, under the weaving of the polyvinyl chloride connecting rib 7, the whitening effect is reduced, the top wall of the polyvinyl chloride connecting rib 7 is fixedly connected with a buffer layer 9, the top wall of the buffer layer 9 is fixedly connected with a protective layer 10, and the bottom wall of the base fabric layer 1 is provided with a protective mechanism 2;

[0040] Specifically, through the connection of the woven mesh 4, the toughness of the tear-resistant layer 3 is improved, thereby effectively reducing the tearing situation. The polyurethane resin reinforcement ribs 5 and the high-strength fiber 6 form a mesh layer, which further improves the overall strength of the artificial leather. The mesh belt composed of the polyvinyl chloride connecting ribs 7 and the synthetic fiber 8 makes it difficult for the molecular chains of polyvinyl chloride to break and displace during the rubbing process of the artificial leather, thereby effectively reducing the whitening phenomenon. Therefore, the tear-resistant layer 3 can increase the service life of the artificial leather, achieve the purpose of improving the durability of the artificial leather, and also obtain a good rubbing resistance effect.

[0041] Reference Figure 1 、 Figure 3 and Figure 5 The protection mechanism 2 includes a connecting layer 201. The top wall of the connecting layer 201 is fixedly connected to the bottom wall of the base fabric layer 1. A plurality of grooves 202 are equidistantly provided on the top wall of the connecting layer 201. With the opening of the plurality of grooves 202, the external impact force is effectively reduced, thereby achieving the effect of pressure dispersion. A plurality of protection strips 203 are fixedly connected to the middle part of the top wall of the connecting layer 201. Connecting strips 204 are fixedly connected to the left and right sides of the top wall of the connecting layer 201. With the connection between the plurality of protection strips 203 and the connecting strips 204, the protection effect of the connecting layer 201 is improved. A plurality of pressure-resistant pads 205 are equidistantly fixedly connected to the bottom wall of the connecting layer 201. With the plurality of pressure-resistant pads 205 arranged equidistantly, an effective protection net is formed.

[0042] Specifically, by opening a plurality of grooves 202 on the top of the connecting layer 201, the pressure generated by the impact can be effectively dispersed and reduced, so that the pressure will not be concentrated at a certain point, but will be dispersed through these grooves 202. A plurality of pressure-resistant pads 205 are arranged and combined in an orderly manner to form a protective net, which further reduces the pressure and has the effect of absorbing shock, thereby improving the protection effect of the artificial leather. Through the blocking and support of multiple protective strips 203 and connecting strips 204, the service life of the artificial leather is extended, thereby enhancing the durability of the artificial leather and ensuring its stability and reliability during long-term use.

[0043] Reference Figure 1 、 Figure 2 and Figure 5 The protective mechanism 2 further includes a waterproof layer 206, the top wall of which is fixedly connected to the bottom wall of the pressure-resistant pad 205; a wear-resistant layer 11 is fixedly connected to the middle of the top wall of the protective layer 10, and the outer shape of the wear-resistant layer 11 adopts a strip-shaped design; a plurality of air holes 12 are opened on the front and rear sides of the top wall of the protective layer 10, and the plurality of air holes 12 are symmetrically designed;

[0044] Specifically, the waterproof layer 206 improves the barrier of the artificial leather to external water vapor and reduces the entry of external water vapor into the interior of the artificial leather. The connection with the wear-resistant layer 11 reduces the wear of the artificial leather by the outside world. The multiple air holes 12 improve the breathability of the artificial leather.

[0045] Reference Figure 1 and Figure 4 The interior of the woven mesh 4 is connected by needle and thread to form a square grid structure; two ultraviolet absorbing layers 13 are fixedly connected to the left and right sides of the top wall of the protective layer 10, and ultraviolet absorbers are provided inside the multiple ultraviolet absorbing layers 13; the antistatic layer 14 is fixedly connected to the front and back sides of the middle of the top wall of the base fabric layer 1, and the horizontal position of the polyurethane resin reinforcement rib 5 is lower than the horizontal position of the polyvinyl chloride connecting rib 7;

[0046] Specifically, by forming a square grid structure inside the woven mesh 4, the toughness of the inner wall of the tear-resistant layer 3 is improved, the ultraviolet absorption layer 13 improves the resistance of the artificial leather to ultraviolet rays and reduces the possibility of damage by ultraviolet rays, and the antistatic layer 14 improves the antistatic effect of the artificial leather and reduces the conduction of static electricity.

[0047] Working principle: When in use, the woven mesh 4 is connected to improve the toughness of the tear-resistant layer 3 and reduce the tearing. Under the mesh layer formed by the polyurethane resin reinforcement ribs 5 and the high-strength fiber 6, the strength of the artificial leather can be improved. The mesh belt composed of the polyvinyl chloride connecting ribs 7 and the synthetic fiber 8 makes it difficult for the molecular chains of polyvinyl chloride to break and displace during the rubbing process of the artificial leather, thereby effectively reducing the whitening phenomenon, so that the tear-resistant layer 3 can achieve the purpose of increasing the service life of the artificial leather and obtain a good rubbing resistance effect. In addition, the multiple grooves 202 opened on the top of the connecting layer 201 can effectively reduce the pressure generated by the impact, so that the pressure can be dispersed. At the same time, under the arrangement and combination of multiple pressure-resistant pads 205, an effective protective net can be formed, which further reduces the pressure and achieves the absorption effect, thereby improving the protection effect on the artificial leather. Under the obstruction of multiple protective strips 203 and connecting strips 204, the service life of the artificial leather is effectively increased.
