Description

Technical Field

[0001] The utility model relates to the technical field of vehicle interior decoration parts, in particular to an artificial leather structure. The utility model also relates to a vehicle provided with the artificial leather structure. Background Art

[0002] At present, the ceiling and other places in the vehicle cabin are usually wrapped with covering parts to cover the internal structure of the body such as sheet metal and increase the texture of the cabin interior. At present, the commonly used covering parts for the ceiling are mainly fabric, artificial leather and genuine leather. Genuine leather is generally only used in luxury models, and most models generally use fabric and artificial leather.

[0003] Most of the existing artificial leather is PVC leather, which is usually a composite material similar to natural leather made by mixing PVC (Polyvinyl chloride) with additives such as plasticizers and stabilizers, coating or laminating it on a substrate such as fabric, and then processing it. Although this PVC leather can meet the needs of covering the vehicle ceiling, it still has shortcomings such as poor touch and easy to produce odor after covering, which is not conducive to improving the quality of vehicle interior decoration. Utility Model Content

[0004] In view of this, the utility model aims to provide an artificial leather structure to help improve the quality of vehicle interior decoration.

[0005] In order to achieve the above object, the technical solution of the utility model is implemented as follows:

[0006] An artificial leather structure comprises a three-dimensional structure layer and a dense layer connected to the three-dimensional structure layer through an adhesive layer. The dense layer adopts a foaming material and is provided with a coating layer on the dense layer, and the coating layer is the surface layer of the artificial leather structure.

[0007] Furthermore, the three-dimensional structure layer includes a first surface layer, a middle layer and a second surface layer arranged in sequence;

[0008] The middle layer includes a plurality of longitudinal support structures located between the first surface layer and the second surface layer, and gaps are left between the longitudinal support structures;

[0009] Hole structures are formed on the first surface layer and the second surface layer, and the thickness of the first surface layer and the thickness of the second surface layer are both smaller than the thickness of the middle layer.

[0010] Furthermore, the three-dimensional structure layer adopts 3D mesh.

[0011] Furthermore, the first surface layer is made of ES fiber, the middle layer and the second surface layer are made of PET fiber, and the second surface layer is connected to the dense layer through the adhesive layer.

[0012] Furthermore, the warp density of the second surface layer is greater than the weft density of the second surface layer.

[0013] Furthermore, the yarn fineness of the second surface layer is 150D or 300D.

[0014] Furthermore, the foaming ratio of the dense layer is between 2.9 and 3.1, and / or the dense layer has hollow holes.

[0015] Furthermore, the thickness of the three-dimensional structure layer is between 3.5 mm and 4.5 mm, and / or the thickness of the dense layer is between 0.2 mm and 0.3 mm.

[0016] Furthermore, the coating layer is made of water-based polyurethane resin, and / or the thickness of the coating layer is within 0.1 mm.

[0017] Compared with the prior art, the utility model has the following advantages:

[0018] The artificial leather structure described in the utility model, by providing a three-dimensional structural layer and a dense layer of foamed material, and providing a coating on the surface, can not only utilize the three-dimensional structural layer and the dense layer to provide better resilience and support, thereby improving the touch of the artificial leather, but also utilize the surface coating to improve the appearance quality of the artificial leather, and further improve the touch of the artificial leather, thereby helping to improve the quality of vehicle interior decoration.

[0019] In addition, the three-dimensional structure layer includes a first surface layer, an intermediate layer, and a second surface layer arranged in sequence, and the intermediate layer is composed of a plurality of longitudinal support structures with gaps, and a hole structure is formed on the first surface layer and the second surface layer, which can form a three-dimensional structure with support and elasticity, which helps to achieve the setting effect of the three-dimensional structure layer. The three-dimensional structure layer adopts 3Dmesh, which can not only utilize the excellent resilience and support of the 3Dmesh structure to improve the touch of the artificial leather, but also utilize the low emission and odor-free characteristics of the 3Dmesh structure to reduce the generation of odor in the artificial leather structure.

[0020] Secondly, the first surface layer is made of ES fiber, and the low melting point of ES fiber can be used to bond the artificial leather structure to the car body through a high-temperature hot-pressing composite process. Compared with the conventional hot-pressing composite process, the glue spraying process can be reduced, and the odor problem after the artificial leather is covered can be reduced. The middle layer and the second surface layer are made of PET fiber, which can meet the use requirements while helping to reduce material costs.

[0021] In addition, by limiting the warp density, weft density and yarn fineness of the second surface layer, the structure of the three-dimensional structure layer using 3Dmesh can be made more solid, which can increase the stability of the overall structure of the artificial leather. By limiting the foaming ratio of the dense layer, the dense layer can be made to have a large foaming ratio, which can increase the softness of the dense layer and reduce the weight of the dense layer. Forming holes in the dense layer helps to further increase the softness of the dense layer and reduce the weight of the dense layer. Using water-based polyurethane resin in the coating can make the surface of the artificial leather smooth and easier to clean dirt, which is beneficial to the cleaning of the artificial leather.

[0022] Another object of the present invention is to provide a vehicle, wherein the vehicle is provided with the artificial leather structure as described above.

[0023] The vehicle described in the utility model can improve the touch of the artificial leather by arranging the above-mentioned artificial leather structure, making it have a texture similar to that of genuine leather, and can reduce the generation of odor, which is beneficial to improving the interior quality of the vehicle.

[0034] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0035] Embodiment 1

[0036] The present embodiment relates to an artificial leather structure, which can be used in a vehicle as an interior covering of a vehicle cabin, and the artificial leather structure can particularly be used as a covering of a vehicle roof to replace conventional fabric or PCV leather.

[0037] In terms of overall structure, combined Figure 1 As shown in the figure, the artificial leather structure of this embodiment includes a three-dimensional structure layer 1, and a dense layer 2 connected to the three-dimensional structure layer 1 through an adhesive layer 4, wherein the dense layer 2 adopts a foaming material, and a coating 3 is also provided on the dense layer 2, and the coating 3 is the surface layer of the artificial leather structure.

[0038] At this time, as set above, by setting a three-dimensional structure layer 1 and a dense layer 2 using a foaming material, and setting a coating 3 on the surface, this embodiment can use the three-dimensional structure layer 1 and the dense layer 2 to provide better resilience and support, thereby improving the touch of the artificial leather, and can also use the surface coating 3 to improve the appearance quality of the artificial leather, and further improve the touch of the artificial leather, thereby achieving the effect of improving the quality of the vehicle interior.

[0039] Based on the above overall introduction, specifically, combined with Figure 2As shown, as a preferred implementation form, the three-dimensional structure layer 1 of this embodiment includes a first surface layer 1a, an intermediate layer 1c and a second surface layer 1b arranged in sequence. Among them, the intermediate layer 1c includes a plurality of longitudinal support structures located between the first surface layer 1a and the second surface layer 1b, and gaps are left between each longitudinal support structure. Hole structures are formed on both the first surface layer 1a and the second surface layer 1b, and structurally, the thickness of the first surface layer 1a and the thickness of the second surface layer 1b are also less than the thickness of the intermediate layer 1c.

[0040] It can be understood that by making the three-dimensional structure layer 1 include a first surface layer 1a, an intermediate layer 2c and a second surface layer 1b arranged in sequence, and the intermediate layer 1c is composed of a plurality of longitudinal support structures with gaps, and a hole structure not shown in the figure is formed on the first surface layer 1a and the second surface layer 1b, the present embodiment can form a three-dimensional structure with support and elasticity, thereby helping to achieve the setting effect of the three-dimensional structure layer 1.

[0041] In addition, based on the above structural form of the three-dimensional structure layer 1, during specific implementation, as a preferred implementation form, for example, the three-dimensional structure layer 1 of this embodiment can specifically adopt 3D mesh.

[0042] 3Dmesh, also known as 3D mesh, 3D spacer fabric, etc., is a warp knitted spacer fabric woven from 2 systems of surface yarns and 1 system of spacer yarns. 3Dmesh adopts an "X-90°" structure, double-sided mesh, and presents a six-sided breathable hollow three-dimensional structure. It can be used as a substitute for materials such as foam or sponge. Due to its structural characteristics, it also has excellent resilience and very good air circulation in all directions, which can significantly improve the touch of artificial leather. At the same time, 3Dmesh also has the characteristics of low emission, no odor, and recyclable materials. It is a healthy and environmentally friendly green product, which is also conducive to reducing the generation of odor in artificial leather structures.

[0043] In this embodiment, for the 3Dmesh structure adopted, reference is still made to Figure 2 As shown in the first surface layer 1a, the middle layer 1c and the second surface layer 1b which are arranged in sequence, the first surface layer 1a and the second surface layer 1b are the surface yarns of the two systems mentioned above, and the above-mentioned hole structure is formed between each surface yarn, the middle layer 1c is the spacer yarn of the one system mentioned above, and the above-mentioned longitudinal supporting structure is composed of each spacer yarn.

[0044] At the same time, the above-mentioned second surface layer 1b is specifically connected to the dense layer 2 through the adhesive layer 4, and preferably, in the specific implementation, the first surface layer 1a can be made of ES (Ethylene-Propylene Side By Side) fiber, for example, and the middle layer 1c and the second surface layer 1b can be made of PET (Polyethylene terephthalate) fiber, for example.

[0045] In this way, the first surface layer 1a in the three-dimensional structural layer 1 using 3Dmesh is made of ES fiber. Since the first surface layer 1a is generally also the bottom layer of the artificial leather structure of this embodiment, the low melting point of ES fiber can be used to bond the artificial leather structure to the car body through a high-temperature hot pressing composite process. Compared with the conventional hot pressing composite process, the glue spraying process can be reduced, and the odor problem after the artificial leather is covered can be reduced.

[0046] In addition, by making the middle layer 1c and the second surface layer 1b use common PET fibers, it can be understood that it can also help reduce material costs while meeting the use requirements.

[0047] In this embodiment, in the three-dimensional structure layer 1 using 3D mesh, since the second surface layer 1b is designed to be generally longer in the warp direction than in the weft direction and needs to have greater strength in the warp direction, therefore, as a preferred implementation form, the warp density of the second surface layer 1b can usually be made greater than the weft density of the second surface layer 1b.

[0048] In specific implementation, the warp density and weft density of the second surface layer 1b can be selected according to specific design requirements, and as an exemplary setting method, for example, the warp density of the second surface layer 1b can be set between 110 coils / 50mm-120 coils / 50mm, and the weft density of the second surface layer 1b can be set between 65 coils / 50mm-75 coils / 50mm. In addition, in addition to the above settings of the warp density and weft density of the second surface layer 1b, this embodiment, as a preferred implementation form, can also set the yarn fineness of the second surface layer 1b to 150D or 300D.

[0049] At this point, it can be understood that, through the above-mentioned limitation on the warp density, weft density and yarn fineness of the second surface layer 1b, the three-dimensional structure layer 1 using 3Dmesh can be made more solid, and the stability of the overall structure of the artificial leather can be increased. In addition, as for the yarn fineness of the second surface layer 1b, it should be pointed out that if the yarn fineness is too coarse, it will affect the fineness, and if the yarn fineness is too fine, it will be easy to break, and it is difficult to meet the use requirements.

[0050] In the specific implementation of this embodiment, it should be pointed out that the warp density of the above-mentioned second surface layer 1b can be, for example, 110 coils / 50mm, 112 coils / 50mm, 115 coils / 50mm or 118 coils / 50mm, 120 coils / 50mm, etc., and the weft density of the second surface layer 1b can be, for example, 65 coils / 50mm, 67 coils / 50mm, 70 coils / 50mm or 72 coils / 50mm, 75 coils / 50mm, etc., and the yarn fineness of the second surface layer 1b can preferably be 300D.

[0051] In this embodiment, the foaming material used in the dense layer 2 can generally be made by foaming conventional polyurethane and other materials, and as a preferred implementation form, during specific implementation, the amount of azodicarbonamide can be increased to make the foaming material adopt a larger foaming ratio compared to the conventional 1.4-1.5, thereby increasing the softness of the dense layer 2 and reducing the weight of the dense layer 2.

[0052] Specifically, the foaming ratio of the dense layer 2 of this embodiment can generally be set between 2.9-3.1, and for example, it can be 2.9, 2.95, 3.0 or 3.1. In addition, based on the use of foaming material in the dense layer 2, especially on the basis that the dense layer 2 can use a large foaming ratio, this embodiment is also Figure 1 as well as Figure 3 As shown in , hollow holes 2a can be formed in the dense layer 2. In this way, by forming the holes 2a in the dense layer 2, it is helpful to further increase the softness of the dense layer 2 and reduce the weight of the dense layer 2.

[0053] In this embodiment, as a preferred implementation form, the coating 3 as the surface layer of the artificial leather structure can be, for example, a water-based polyurethane resin.

[0054] At this time, the coating 3 is made of water-based polyurethane resin, which can make the surface of the artificial leather smooth and easier to clean up dirt, and is conducive to the cleaning of the artificial leather. However, except adopting the water-based polyurethane resin, the coating 3 of the present embodiment can certainly also adopt other materials according to specific design needs.

[0055] In this embodiment, during specific implementation, the adhesive layer 4 may generally be made of a polyvinyl chloride adhesive to ensure the reliability of the connection between the three-dimensional structure layer 1 and the dense layer 2 .

[0056] In addition, the thickness t of the three-dimensional structure layer 1 of this embodiment can be set, for example, between 3.5 mm and 4.5 mm, the thickness s of the dense layer 2 can be set, for example, between 0.2 mm and 0.3 mm, and the thickness m of the coating 3 should generally be within 0.1 mm.

[0057] In specific implementation, the thickness t of the three-dimensional structure layer 1 can be, for example, 3.5 mm, 3.8 mm, 4.0 mm, 4.2 mm or 4.5 mm, the thickness s of the dense layer 2 can be, for example, 0.2 mm, 0.25 mm or 0.3 mm, and the thickness m of the coating layer 3 can be, for example, 0.03 mm or 0.05 mm.

[0058] The artificial leather structure of this embodiment adopts a three-dimensional structure layer 1, a dense layer 2 and a coating 3 arranged in sequence. Not only can the three-dimensional structure layer 1 and the dense layer 2 be used to provide better resilience and support to improve the touch of the artificial leather, but the surface coating 3 can also be used to improve the appearance quality of the artificial leather and further improve the touch of the artificial leather, which is beneficial to improving the quality of vehicle interior decoration.

[0059] Embodiment 2

[0060] This embodiment relates to a vehicle, in which the artificial leather structure in the first embodiment is provided.

[0061] In the vehicle of this embodiment, the artificial leather structure can be used as a covering member of the vehicle roof as mentioned in the first embodiment to improve the overall quality of the covered roof. However, in addition to being used for covering the roof, the artificial leather structure can also be used for covering instrument panels or vehicle doors to improve the covering quality of instrument panels and vehicle doors.

[0062] The vehicle of this embodiment adopts the artificial leather structure in the first embodiment, which can improve the touch of the artificial leather and reduce the generation of odor from the artificial leather structure, thereby helping to improve the quality of the vehicle interior.
