Fig. 1 is a schematic cross-sectional structure of a cover according to an embodiment of the present application, and fig. 2 is a schematic structural diagram of a cover according to an embodiment of the present application. As an example, as shown in connection with fig. 1 and 2, the cover includes a base plate 01 and an artificial leather 02. The artificial leather 02 is located on one side of the substrate 01 and is bonded to the substrate 01. Specifically, the substrate 01 is located on the side of the artificial leather 02 where the base fabric layer 1 is away from the functional layer 2, and is connected to the base fabric layer 1.
Fig. 3 is a schematic structural view of an artificial leather according to an embodiment of the present application, and fig. 4 is a schematic sectional structural view of an artificial leather according to an embodiment of the present application. As an example, as shown in fig. 3 and 4, the artificial leather includes a base fabric layer 1 and a functional layer 2. The base fabric layer 1 and the functional layer 2 are arranged in a stacked manner, i.e. the functional layer 2 is located on one side of the base fabric layer 1 and is connected to said base fabric layer 1. And, the surface of the functional layer 2 far from the base cloth layer 1 is provided with a texture pattern.
As an example, the base fabric layer 1 may be a textile, such as gauze or the like. By adopting the scheme, the textile is softer, the tensile property of the textile is stronger, and the textile is not easy to deform when being pulled by external force, so that the textile is taken as the base cloth layer 1, the artificial leather can be kept high in flexibility after being manufactured, and the quality of the artificial leather can be improved.
Alternatively, the base cloth layer 1 may be made of glass fiber, resin fiber, etc., and it should be noted that it is necessary to ensure that the base cloth layer 1 satisfies the tensile strength and fatigue strength of the artificial leather. The material of the base fabric layer 1 is only exemplified herein, and is not limited in any way.
As an example, the thickness of the base cloth layer 1 ranges from 0.1 mm to 0.4 mm, such as 0.2 mm, etc. The thickness of the base fabric layer 1 may be designed according to the strength requirement of the actual product, and is merely illustrative and not limited in any way.
By way of example, the functional layer 2 may be made of a silicone material, which is advantageous for improving the strength of the artificial leather and also for improving the feel of the artificial leather, and the material of the functional layer 2 is only exemplified herein and is not limited in any way.
As an example, the thickness of the functional layer 2 ranges from 0.05 mm to 0.3 mm, such as 0.1 mm, 0.15 mm, 0.25 mm, etc. The thickness of the functional layer 2 can be designed according to the strength requirement of the actual product and the thickness dimension of the texture pattern, and is only exemplified herein without any limitation.
In the scheme provided by the embodiment of the application, the cover body comprises a substrate 01 and artificial leather 02, the artificial leather comprises a base cloth layer 1 and a functional layer 2, and the surface of the functional layer 2, which is far away from the base cloth layer 1, is provided with a texture pattern. The base cloth layer 1 has a supporting function on the functional layer 2 and can improve the tensile strength of the functional layer 2, thereby being beneficial to prolonging the service life of the artificial leather.
In some examples, as shown in fig. 3, the surface of the functional layer 2 away from the base fabric layer 1 has a receiving area 2A, and a plurality of texture units 2B are distributed in the receiving area 2A to form a texture pattern.
As an example, as shown in fig. 3, the accommodation area 2A may be a groove, the plurality of texture units 2B are located at the bottom surface of the groove, and the height of the texture units 2B is equal to the depth of the groove.
Alternatively, the height of the texture unit 2B is smaller than the depth of the groove, or the height of the texture unit 2B is larger than the depth of the groove, or, alternatively, the height of one part of the texture unit 2B is equal to the depth of the groove and the height of the other part is smaller than the depth of the groove. The height of the texture unit 2B may be designed according to the requirements of the actual product for visual effect, and is not limited in any way.
Alternatively, the receiving area 2A may be a protrusion, in particular, the top surface of the protrusion is higher than the surface of the functional layer 2 remote from the base cloth layer 1. The texture unit 2B is located on the top surface of the protrusion, wherein the texture unit 2B may have a protrusion structure or a groove structure. The texture unit is not limited in any way herein with respect to its morphological structure and size.
Alternatively, the receiving area 2A may be a plane, specifically, a specific area on the surface of the functional layer 2 away from the base fabric layer 1 is the receiving area 2A, or the surface of the functional layer 2 away from the base fabric layer 1 is the receiving area 2A.
As an example, as shown in fig. 3, the texture unit 2B array distribution forms the texture pattern shown in fig. 3. With this scheme, a regular texture pattern can be formed.
Alternatively, the texture units 2B may be distributed in a linear array, may be distributed in a circumferential array, may be symmetrically distributed, or the like. The texture units 2B may also be arranged irregularly. The arrangement of the texture units 2B is not limited in any way.
Alternatively, the texture pattern described above is not composed of texture elements 2B, but is randomly generated from several lines and points. By adopting the scheme, the artificial leather has a richer visual effect.
Fig. 5 is a schematic cross-sectional view of an artificial leather according to an embodiment of the present application. As an example, as shown in fig. 5, the artificial leather further comprises a wear layer 3. The wear-resistant layer 3 is positioned on the surface of the functional layer 2 away from the base cloth layer 1 and is attached to the functional layer 2.
By way of example, the wear layer 3 may be made of all silicon, with which it is advantageous to have a wear layer 3 with a high wear resistance. The wear-resistant layer 3 is attached to the surface of the functional layer 2, so that the functional layer 2 can be protected, and the texture patterns on the surface of the functional layer 2 are prevented from being worn. Furthermore, since the functional layer 2 is generally made of organic silicon, the wear-resistant layer 3 is made of all-silicon, which is advantageous for close adhesion between the wear-resistant layer 3 and the functional layer 2.
Alternatively, the wear-resistant layer 3 may be made of ultra-high molecular weight polyethylene, chromium carbide composite material, high carbon multi-alloy steel, or the like. It should be noted that the wear-resistant layer 3 needs to be tightly adhered to the functional layer 2 while having high wear resistance, and needs to have good bending ability to ensure that the wear-resistant layer 3 does not cause a large obstruction when the artificial leather is bent. The material of the wear-resistant layer 3 is only exemplified here and is not limited in any way.
As an example, the wear-resistant layer 3 is in a transparent state, so that the texture pattern on the surface of the functional layer 2 can be clearly seen while protecting the functional layer 2.
Alternatively, the wear-resistant layer 3 may have a specific light-transmitting effect, so that different visual effects can be obtained after the wear-resistant layers 3 with different light-transmitting effects are respectively disposed on the surfaces of the different functional layers 2.
By way of example, the thickness of the wear layer 3 may range from 0.05 mm to 0.3 mm, such as 0.1 mm, 0.15 mm, 0.25 mm, etc. The thickness of the wear-resistant layer 3 can be designed according to the wear resistance requirements of the actual product, and is only exemplified here without any limitation.
In some examples, as shown in fig. 5, the artificial leather may further include an anti-soil layer 4. When the artificial leather includes the stain-resistant layer 4 instead of the abrasion-resistant layer 3, the stain-resistant layer 4 may be located on the surface of the functional layer 2 remote from the base cloth layer 1 and is adhered to the functional layer 2.
In other examples, fig. 6 is a schematic cross-sectional structure of an artificial leather according to an embodiment of the present application, and as shown in fig. 6, the artificial leather further includes a wear-resistant layer 3 and a stain-resistant layer 4. In this case, the anti-fouling layer 4 is located on the surface of the wear-resistant layer 3 away from the functional layer 2, and is attached to the wear-resistant layer 3.
As an example, the anti-fouling layer 4 may be made of silicone or all-silicon. By adopting the scheme, the anti-fouling layer 4 is attached to the surface of the functional layer 2 or the wear-resistant layer 3, can play an anti-fouling role on the functional layer 2 or the wear-resistant layer 3, prevents the surface of the functional layer 2 or the wear-resistant layer 3 from being stained with oil stains and other dirty matters, and is beneficial to enhancing the visual effect of the artificial leather.
Alternatively, the anti-fouling layer 4 may be made of an acrylic resin or an Ultraviolet (UV) curable resin or the like. It should be noted that the anti-fouling layer 4 needs to be closely attached to the functional layer 2 or the wear-resistant layer 3 while having high anti-fouling capability, and needs to have good bending capability to ensure that the anti-fouling layer 4 does not cause a large obstruction when the artificial leather is bent. The material of the stain-resist layer 4 is only exemplified here, and is not limited in any way.
As an example, the anti-smudge layer 4 is in a transparent state, so that the functional layer 2 or the wear layer 3 is protected from smudging, while the texture pattern on the surface of the functional layer 2 is clearly visible.
Alternatively, the anti-smudge layer 4 may also have a specific light-transmitting effect, so that under the effect of the wear-resistant layer 3 of different light-transmitting effects, artificial leather with different visual effects may be obtained.
As an example, the anti-fouling layer 4 is typically disposed on the surface of the functional layer 2 or the wear layer 3 by means of curtain coating or spray coating, and the thickness of the anti-fouling layer 4 ranges from 0.01 mm to 0.1 mm, such as 0.05 mm, 0.08 mm, etc. The thickness of the anti-fouling layer 4 can be designed according to the anti-fouling requirements of the actual product, and is only exemplified here and is not limited in any way.

The base cloth layer 1 has a supporting function on the functional layer 2 and can improve the tensile strength of the functional layer 2, thereby being beneficial to prolonging the service life of the artificial leather.
