Description

Technical Field

[0001] This utility model relates to the field of artificial leather technology, and more specifically, to an 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] Existing synthetic leather consists of an outer skin layer and a base fabric layer. The outer skin layer is usually made of materials such as PVC and PU, while the base fabric layer is a fiber layer woven from several yarns. The outer skin layer and the base fabric layer are usually bonded together with adhesives. The appearance, feel, and performance of synthetic leather are close to those of natural leather, and it can replace natural leather to a certain extent. However, synthetic leather is less breathable than natural leather, and air circulation is difficult in actual use, which leads to a certain odor after long-term use. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a kind of artificial leather.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: an artificial leather, comprising an epidermis layer and a base fabric layer, wherein the base fabric layer comprises comb GB1 yarn, comb GB2 yarn and comb GB3 yarn, wherein the comb GB1 yarn and comb GB2 yarn are woven together to form a warp-knitted mesh structure, wherein the comb GB3 yarn forms a weft-inserted structure, wherein a breathable space is formed between two adjacent weft-inserted structures, and wherein a plurality of breathable holes are provided on the surface of the epidermis layer.

[0006] The present invention is further configured such that: the padding yarn number of the GB1 comb yarn is 1-0 / 1-2 / 2-3 / 2-1 / / one thread and one empty, the padding yarn number of the GB2 comb yarn is 2-3 / 2-1 / 1-0 / 1-2 / / one thread and one empty, and the padding yarn number of the GB3 comb yarn is 0-0 / 4-4 / / one thread and one empty.

[0007] The present invention is further configured such that: the comb GB3 yarn includes a yarn core and two wrapped yarns wrapped around the yarn core, both of which are made of bamboo charcoal fiber twisted together.

[0008] The present invention is further configured such that the diameter of the first covering yarn is greater than the diameter of the second covering yarn.

[0009] The present invention is further configured such that the yarn core is made of several nylon fibers twisted together.

[0010] The present invention is further configured such that the outer skin layer is a PVC resin layer.

[0011] In summary, this utility model has the following beneficial effects: In this utility model, the weft weft structure formed by the GB3 comb yarn forms a raised strip on the surface of the base fabric layer. When the outer layer and the base fabric layer are bonded and fixed, the top of the raised strip abuts against the outer layer, thus forming a breathable space between the base fabric layer and the outer layer. Air on the side closer to the base fabric layer can enter the breathable space through the warp-knitted mesh structure and then exit through the vent holes. Air on the side closer to the outer layer can enter the breathable space through the vent holes and then exit through the warp-knitted mesh structure. Through the combination of the vent holes, the warp-knitted mesh structure, and the breathable space, the air circulation on both sides of the artificial leather is greatly increased, giving the artificial leather a better overall breathability, which helps the generated odor to dissipate quickly and reduces odor residue.

[0018] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0019] See Figure 1-4As shown, an artificial leather includes a surface layer 1 and a base fabric layer 2. The surface layer 1 is a PVC resin layer. PVC resin has good wear resistance and corrosion resistance, thus ensuring a long service life for the artificial leather. The surface layer 1 and the base fabric layer 2 are bonded together with adhesive. The base fabric layer 2 is integrally woven using a warp knitting machine. The base fabric layer 2 includes guide bar yarns GB1, GB2, and GB3. The guide bar yarns GB1 and GB2 are woven together to form a warp-knitted mesh structure, and the guide bar yarns GB3 form a weft-inserted structure. Breathable spaces are formed between adjacent weft-inserted structures. Several ventilation holes 3 are laser-engraved on the surface of the surface layer 1. Based on the base fabric layer 2, the weft weave formed by the combed GB3 yarn creates raised strips on the surface of the base fabric layer 2. When the outer skin layer 1 is bonded and fixed to the base fabric layer 2, the top of the raised strips abuts against the outer skin layer 1, thus creating a breathable space between the base fabric layer 2 and the outer skin layer 1. Air on the side closer to the base fabric layer 2 can enter the breathable space through the warp-knitted mesh and then exit through the vent 3. Air on the side closer to the outer skin layer 1 can enter the breathable space through the vent 3 and then exit through the warp-knitted mesh. Through the combination of the vent 3, the warp-knitted mesh, and the breathable space, the airflow on both sides of the artificial leather is greatly increased, giving the artificial leather a better overall breathability. This helps to quickly dissipate any odors and reduce odor residue.

[0020] See Figure 1-5 As shown, the padding yarn numbers for GB1 combed yarn are 1-0 / 1-2 / 2-3 / 2-1 / / one thread and one empty; the padding yarn numbers for GB2 combed yarn are 2-3 / 2-1 / 1-0 / 1-2 / / one thread and one empty; and the padding yarn numbers for GB3 combed yarn are 0-0 / 4-4 / / one thread and one empty. GB3 combed yarn includes a yarn core 4 and two wrapping yarns 5 and 6 wound around the yarn core 4. Both wrapping yarn 5 and wrapping yarn 6 are made of twisted bamboo charcoal fiber, which has excellent deodorizing properties. The yarn core 4 is made of twisted nylon fibers. Nylon fibers have good tensile strength, which ensures that the artificial leather has good tensile strength.
