Description

Technical Field

[0001] This utility model relates to artificial leather, and more specifically, to a long-life artificial leather. Background Technology

[0002] Artificial leather is made by foaming or coating various formulations of PVC and PU onto a woven or non-woven fabric base. It can be processed according to different requirements for strength, color, gloss, and patterns.

[0003] Chinese Patent Publication No. CN215620590U discloses an artificial leather, the key technical point of which is: it includes an interconnected epidermal layer and a base fabric layer, wherein the base fabric layer includes a plurality of first yarns, and the first yarns are integrally connected to the epidermal layer. This invention effectively improves the connection effect between the base fabric layer and the epidermal layer by setting the first yarns forming the base fabric layer to be integrally connected to the epidermal layer.

[0004] However, the first yarn and the outer layer of this type of artificial leather are connected together by melting. However, after a period of time, when the outer layer ages, the first yarn and the outer layer are prone to separate. As a result, when the surface of the artificial leather is scratched or broken by external force, the damaged part on the outer layer will fall off directly, thus reducing the service life of the artificial leather. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a long-life artificial leather.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a long-life artificial leather, comprising an epidermis, a nap layer and a tensile layer, wherein the epidermis and the nap layer are fixed together by hot pressing and melting, and the nap layer and the tensile layer are stitched together, wherein the surface of the nap layer is formed with a plurality of naps by a napping process, and a plurality of through holes are provided on the nap layer.

[0007] The present invention is further configured such that the tensile layer is formed by weaving several tensile yarns together.

[0008] The present invention is further configured such that: the pile layer includes comb GB1 yarn and comb GB2 yarn, and the comb GB1 yarn and comb GB2 yarn are woven together to form a warp-knitted mesh structure.

[0009] The present invention is further configured such that: the padding yarn number of the GB1 comb yarn is 1-0 / 1-3 / 3-4 / 3-1 / / one thread and two empty spaces, and the padding yarn number of the GB2 comb yarn is 3-4 / 3-1 / 1-0 / 1-3 / / one thread and two empty spaces.

[0010] The present invention is further configured such that both the GB1 and GB2 comb yarns are made of twisted cotton fibers.

[0011] The present invention is further configured such that: the tensile yarn includes a yarn core and a covering yarn wrapped around the surface of the yarn core, the yarn core is made of several polyester fibers twisted together, and the covering yarn is made of several cotton fibers twisted together.

[0012] In summary, this utility model has the following beneficial effects: By opening through holes, this utility model not only increases the contact area between the pile layer and the molten skin layer, but also ensures a stable connection between the molten skin layer and the tensile layer. This makes it less likely for the skin layer and pile layer to separate after hot pressing and melting. At the same time, after the skin layer cools, the pile on the surface of the pile layer can fully fuse with the skin layer, thereby exerting a traction effect on the skin layer and further improving the connection strength between the skin layer and the pile layer, making it less likely for the skin layer to fall off the pile layer. The addition of the tensile layer improves the overall tensile strength of the artificial leather and can effectively reduce the possibility of the skin layer breaking under tension. Thus, through the cooperation between the tensile layer and the pile layer, the artificial leather as a whole has a longer service life. Attached Figure Description

[0019] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0020] See Figure 1As shown, a long-life artificial leather includes a skin layer 1, a nap layer 2, and a tensile layer 3. The skin layer 1 and the nap layer 2 are fixed together by hot-pressing and melting. The nap layer 2 and the tensile layer 3 are stitched together. A napping process is used to create a nap on the surface of the nap layer 2. Several through holes 4 are formed on the nap layer 2. When the nap layer 2 and the skin layer 1 are fixed by hot-pressing and melting, the molten skin layer 1 covering the surface of the nap layer 2 can enter the through holes 4, which not only increases the contact area between the nap layer 2 and the skin layer 1, but also ensures a stable connection between the skin layer 1 and the tensile layer 3. This design makes it difficult for the outer skin layer 1 and the pile layer 2 to separate after being fixed by hot pressing. At the same time, after the outer skin layer 1 cools, the pile on the surface of the pile layer 2 can fully fuse with the outer skin layer 1, thereby exerting a traction effect on the outer skin layer 1. This further enhances the connection strength between the outer skin layer 1 and the pile layer 2, making it less likely for the outer skin layer 1 to fall off the pile layer 2. The addition of the tensile layer 3 improves the overall tensile strength of the artificial leather, effectively reducing the possibility of the outer skin layer 1 breaking under tension. Through the cooperation between the tensile layer 3 and the pile layer 2, the artificial leather as a whole has a long service life.

[0021] See Figure 2 , Figure 5 As shown, the tensile layer 3 is formed by weaving several tensile yarns 5. The tensile yarn 5 includes a yarn core 6 and a covering yarn 7 wrapped around the surface of the yarn core 6. The yarn core 6 is made of several polyester fibers twisted together, and the covering yarn 7 is made of several cotton fibers twisted together. Polyester fibers have high strength and good tensile strength, which makes the tensile yarn 5 have good tensile performance, thus ensuring the tensile effect of the tensile layer 3. Cotton fibers have good comfort and breathability, thus ensuring that the tensile layer 3 has good comfort.

[0022] See Figure 3-4 As shown, the pile layer 2 is integrally woven by a warp knitting machine, including guide bar GB1 yarn and guide bar GB2 yarn. The guide bar GB1 yarn and guide bar GB2 yarn are woven together to form a warp knitted mesh structure. The padding yarn number of the guide bar GB1 yarn is 1-0 / 1-3 / 3-4 / 3-1 / / one thread and two gaps, and the padding yarn number of the guide bar GB2 yarn is 3-4 / 3-1 / 1-0 / 1-3 / / one thread and two gaps. The padding yarn number of the guide bar GB1 yarn is 1-0 / 1-3 / 3-4 / 3-1 / / one thread and two gaps, and the padding yarn number of the guide bar GB2 yarn is 3-4 / 3-1 / 1-0 / 1-3 / / one thread and two gaps. Both the guide bar GB1 yarn and the guide bar GB2 yarn are made of twisted cotton fibers. Cotton fibers are natural fibers, soft in texture, and have a good napping effect.
