Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of clothing auxiliary materials, and more specifically, to wear-resistant composite leather. Background Art
[0002] Leather is a commonly used accessory material for clothing and luggage, including natural leather and synthetic leather. Synthetic leather is widely used because it is easy to clean and cheap.
[0003] Polyurethane is commonly used to make synthetic leather, because leather made of polyurethane has good tear strength, tensile strength and folding resistance, mainly because of its good simulation.
[0004] However, when this type of leather is exposed to the sun for a long time, the volatile organic compounds inside will evaporate faster due to the increase in temperature, causing the leather to produce an odor.
[0005] Therefore, the application provides a technical solution to this technical problem. Utility Model Content
[0006] In view of the deficiencies in the prior art, the utility model aims to provide wear-resistant composite leather.
[0007] The above technical objectives of the utility model are achieved through the following technical solutions:
[0008] The wear-resistant composite leather comprises a base fabric layer, a support layer, a leather layer and a coating layer. The support layer is provided with a plurality of clearance openings on the side facing the leather layer, and a connecting cloth is bonded and fixed to the side wall of the clearance opening. The leather layer is provided with a plurality of through openings, some of which correspond to the clearance openings, and some of the connecting cloth is provided with a fragrance volatile layer on the side facing the leather layer.
[0009] The utility model is further configured as follows: a nano titanium dioxide coating is provided on the side of the other part of the connecting cloth facing the leather layer.
[0010] The utility model is further configured that: the aromatic volatile layer is formed by aromatic microcapsule finishing liquid.
[0011] The utility model is further configured as follows: the support layer is made of sponge material, and the connecting cloth is woven from breathable yarn.
[0012] The utility model is further configured as follows: the breathable yarn is woven from a plurality of polyester special-shaped fibers with a Y-shaped cross-section.
[0013] The utility model is further configured that: the coating layer is formed by curing polyurethane emulsion.
[0014] In summary, the utility model has the following beneficial effects:
[0015] When light shines on the leather surface, part of the light will shine on the nano titanium dioxide coating through the hole. The nano titanium dioxide coating will rely on photocatalysis to sterilize and absorb the odor produced by the heating of the leather. At the same time, the heat will accelerate the speed at which the aromatic volatile layer produces volatiles, giving the leather a certain aromatic effect. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside" and "outside" indicate directions or positional relationships based on the directions or positional relationships shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention. Obviously, the embodiments described are only some embodiments of the present invention, rather than all embodiments.
[0021] like Figure 1 and Figure 2 As shown, the present application provides a wear-resistant composite leather, including a base fabric layer 1, a supporting layer 2, a leather layer 3 and a coating layer 4. The supporting layer 2 is made of a sponge material, so as to increase the overall softness and elasticity of the leather, and the coating layer 4 is formed by curing a polyurethane emulsion, which can protect and decorate the leather layer 3, thereby improving the service life and aesthetics of the leather.
[0022] like Figure 3As shown, the support layer 2 is provided with a plurality of clearance openings 5 on the side facing the leather layer 3, and a connecting cloth 6 is bonded and fixed to the side wall of the clearance opening 5, the connecting cloth 6 is woven from a breathable yarn 8, and the breathable yarn 8 is woven from a plurality of strands of polyester shaped fibers 9 with a Y-shaped cross-section. Due to the cross-sectional shape of the polyester shaped fibers 9, the ventilation effect of the breathable yarn 8 can be improved, making it easier for gas to pass through the connecting cloth 6, and the leather layer 3 is provided with a plurality of through openings 7, some of which correspond to the clearance openings 5, and the outside air can pass through the leather layer 3 through the through openings 7.
[0023] When the leather is squeezed, the volume of the supporting layer 2 is reduced due to the sponge, and the air in the sponge will pass through the connecting cloth 6 and squeeze out of the leather through the hole 7. After the leather stops being squeezed, the supporting layer 2 will absorb the outside air, thereby improving the fluidity of the air and increasing the breathability of the leather.
[0024] like Figure 1 and Figure 2 As shown, a plurality of openings 5 are arranged at intervals, wherein a portion of the connecting cloth 6 is provided with a fragrance volatile layer 10 on the side facing the leather layer 3, the fragrance volatile layer 10 is formed by a fragrance microcapsule finishing liquid, and the fragrance volatile layer 10 contains many fragrance microcapsules, and another portion of the connecting cloth 6 is provided with a nano titanium dioxide coating 11 on the side facing the leather layer 3.
[0025] When light is irradiated on the leather surface, part of the light will irradiate the nano titanium dioxide coating 11 through the hole 7. The nano titanium dioxide coating 11 will rely on photocatalysis to sterilize and absorb the odor generated by the heating of the leather. At the same time, the heat will accelerate the speed at which the aromatic volatile layer 10 produces volatiles, making the leather have a certain aromatic effect, and ultimately reducing the odor generated by the leather when exposed to the sun.
[0026] The above is only a preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
