Description

Technical Field

[0001] The utility model relates to the technical field of artificial leather, in particular to a highly cold-resistant PVC artificial leather with a multi-layer structure. Background Art

[0002] Polyvinyl chloride artificial leather (PVC leather) is a paste made by coating PVC resin, plasticizer, stabilizer and other additives on fabric. Or it is coated with a layer of PVC film and then processed through a certain process. The product has high strength, is easy to process and has low cost. It can be used to make various bags, seat covers, linings, sundries, etc. At present, the cold-resistant artificial leather on the market only has a certain cold-resistant effect by setting foam plastic inside it. For example, a cold-resistant artificial leather disclosed in Chinese patent announcement number CN202626718U, but because the cold-resistant material is relatively single, the cold-resistant effect of the artificial leather is poor, which cannot meet people's usage needs. In addition, due to the poor waterproof performance of the artificial leather, the artificial leather is easily soaked by water, and the cold resistance is reduced. At the same time, since the floating dust in the air will be adsorbed on the artificial leather, the surface of the artificial leather will often be adsorbed with floating dust, which will reduce the aesthetics of the artificial leather. Utility Model Content

[0003] The purpose of the utility model is to solve the shortcomings existing in the prior art. For example, at present, the cold-resistant artificial leather on the market only has a certain cold-resistant effect by arranging foam plastic inside the artificial leather. However, due to the relatively single cold-resistant material, the cold-resistant effect of the artificial leather is poor, which cannot meet people's usage needs. In addition, due to the poor waterproof performance of the artificial leather, the artificial leather is easily soaked by water, which reduces the cold resistance. At the same time, since the floating dust in the air will be adsorbed on the artificial leather, the surface of the artificial leather will often be adsorbed with floating dust, which reduces the aesthetics of the artificial leather. Therefore, a multi-layer structure of highly cold-resistant PVC artificial leather is proposed.

[0004] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0005] A multi-layered, highly cold-resistant PVC artificial leather comprises a PVC surface layer, a windproof layer bonded to the bottom of the PVC surface layer, a PVC foam layer bonded to the bottom of the windproof layer, a PVC dense layer bonded to the bottom of the PVC foam layer, an antibacterial layer bonded to the bottom of the PVC dense layer, a self-heating fiber layer bonded to the bottom of the antibacterial layer, a thermal insulation layer bonded to the bottom of the self-heating fiber layer, and a base fabric layer bonded to the bottom of the thermal insulation layer.

[0006] Preferably, the windproof layer includes a polyester layer and a windproof membrane, the bottom of the polyester layer is bonded to the upper surface of the PVC foam layer, and the upper and lower sides of the windproof membrane are bonded to the upper surface of the polyester layer and the bottom of the PVC surface layer respectively.

[0007] Preferably, the thermal insulation layer is formed by blending cashmere fibers and cotton fibers.

[0008] Preferably, the self-heating fiber layer is made of EKS fiber.

[0009] Preferably, a waterproof layer is bonded to the upper surface of the PVC surface layer.

[0010] Preferably, an antistatic layer is bonded to the upper surface of the waterproof layer.

[0011] Compared with the prior art, the beneficial effects of the present invention are:

[0012] (1) The utility model adds a windproof layer and a heat-insulating layer to the artificial leather, so that the artificial leather has a strong windproof and heat-insulating effect, and the strong windproof and heat-insulating effect improves the cold resistance of the artificial leather. At the same time, the self-heating fiber layer in the artificial leather can store the heat in the sweat in the artificial leather after absorbing sweat, and the artificial leather has moisture absorption and heat release properties, thereby improving the cold resistance of the artificial leather.

[0013] (2) The present invention adds a waterproof layer to the artificial leather, and the waterproof layer is made of a TPU film with strong waterproof performance. The waterproof layer makes the surface of the artificial leather have strong waterproof performance, thereby preventing the artificial leather from being soaked in water and causing a reduction in cold resistance. At the same time, by adding an antistatic layer to the surface of the artificial leather, it is difficult for floating dust in the air to be adsorbed on the surface of the artificial leather, thereby preventing the surface of the artificial leather from being adsorbed with floating dust and causing a reduction in the aesthetics of the artificial leather.

[0019] Example 1:

[0020] Reference Figure 1-2 A multi-layered, highly cold-resistant PVC artificial leather comprises a PVC surface layer 1, a windproof layer 2 is bonded to the bottom of the PVC surface layer 1, a PVC foam layer 3 is bonded to the bottom of the windproof layer 2, a PVC dense layer 4 is bonded to the bottom of the PVC foam layer 3, an antibacterial layer 5 is bonded to the bottom of the PVC dense layer 4, and a self-heating fiber layer 6 is bonded to the bottom of the antibacterial layer 5. The self-heating fiber layer 6 is made of EKS fiber. After absorbing sweat, the self-heating fiber layer 6 can store the heat in the sweat in the artificial leather and make the artificial leather have moisture absorption and heat release properties, thereby improving the cold resistance of the artificial leather. The bottom of the self-heating fiber layer 6 is bonded with a thermal insulation layer 7, which is a blend of cashmere fiber and cotton fiber. The thermal insulation layer 7 makes the artificial leather have strong thermal insulation performance, and the strong thermal insulation performance makes the cold resistance of the artificial leather improved. The bottom of the thermal insulation layer 7 is bonded with a base fabric layer 8.

[0021] The windproof layer 2 includes a polyester layer 21 and a windproof membrane 22. The bottom of the polyester layer 21 is bonded to the upper surface of the PVC foam layer 3, and the upper and lower sides of the windproof membrane 22 are respectively bonded to the upper surface of the polyester layer 21 and the bottom of the PVC surface layer 1. Through the cooperation of the polyester layer 21 and the windproof membrane 22, the windproof layer 2 has a strong windproof effect. Furthermore, by adding the windproof layer 2 to the artificial leather, the artificial leather has a strong windproof effect and the cold resistance of the artificial leather is improved.

[0022] Example 2:

[0023] Reference Figure 1The upper surface of the PVC surface layer 1 is bonded with a waterproof layer 9, which is made of a TPU film with strong waterproof performance. The waterproof layer 9 makes the surface of the artificial leather have strong waterproof properties, thereby preventing the artificial leather from being soaked in water and causing the cold resistance to decrease. The upper surface of the waterproof layer 9 is bonded with an antistatic layer 10, which is coated with an antistatic coating. By adding the antistatic layer 10 to the surface of the artificial leather, floating dust in the air is not easily adsorbed on the surface of the artificial leather, thereby preventing the surface of the artificial leather from being adsorbed with floating dust, which reduces the aesthetics of the artificial leather.
