Description

Technical Field

[0001] The utility model relates to the technical field of leather, and more specifically to an environmentally friendly breathable and enhanced leather. Background Art

[0002] Natural leather can be divided into pig leather, cow leather, sheep leather, horse leather, donkey leather and kangaroo leather, etc., and a small amount of fish leather, reptile leather, amphibian leather, ostrich leather, etc.; among them, cow leather can be divided into yellow cattle leather, buffalo leather, yak leather and yak leather; sheep leather can be divided into sheep leather and goat leather;

[0003] Vegetable tanned natural leather: avoids the use of heavy metal chromium salts, greatly reduces environmental pollution during leather processing, and meets the requirements of modern environmental protection and sustainable development. Vegetable tanning agents are mostly derived from plants in nature, such as tannin (extracted from plants such as oak), bark extracts, etc., which are all renewable resources;

[0004] The existing (publication (announcement) number: CN205705547U, a novel composite environmentally friendly breathable natural leather) only proposes to use channels and cavities to provide a breathable function, that is, there is still a disadvantage that the breathability of the "natural leather" material itself is insufficient. Utility Model Content

[0005] The purpose of the utility model is to provide an environmentally friendly breathable reinforced leather in order to solve the above technical problems.

[0006] In order to achieve the above-mentioned purpose, the utility model specifically adopts the following technical solutions:

[0007] The utility model provides an environmentally friendly breathable reinforced leather, comprising:

[0008] Vegetable tanned natural leather layer with fine grooves on the outside of the natural leather layer;

[0009] It also includes a permeable protective layer, which fills part of the fine grooves and is fitted and fixed on the outer side of the natural leather layer;

[0010] A filling layer, which fills the fine grooves and is fixedly arranged on the outside of the seepage layer;

[0011] A polishing layer, which is arranged outside the filling layer;

[0012] The polishing agent layer is fixedly arranged on the outer side of the polishing layer.

[0013] As a preferred technical solution of the utility model, the penetration protection layer is a natural oil layer.

[0014] As a preferred technical solution of the utility model, the protective filling layer is a water-based polyurethane layer.

[0015] As a preferred technical solution of the utility model, the polishing agent layer is a natural wax layer.

[0016] As a preferred technical solution of the utility model, it also includes a wear-resistant layer, which is fixedly arranged on the outer side of the polishing agent layer.

[0017] The beneficial effects of the utility model are as follows:

[0018] The natural leather layer 1 is subjected to infiltration softening treatment by using natural oil or environmentally friendly softener until a protective permeable protective layer 2 is formed on the surface of the natural leather layer 1 to improve its air permeability, and then a filling layer 3 is arranged on the surface of the permeable protective layer 2 to strengthen protection, and then a polishing layer 4 is arranged on the filling layer 3, and then a polishing agent layer 5 is used to improve the surface smoothness and aesthetics; at the same time, a wear-resistant layer 6 is arranged on the outside of the polishing agent layer 5 to improve the strength. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] Figure 1 It is a structural schematic diagram of the utility model.

[0020] Figure numerals: natural leather layer-1, penetration protection layer-2, filling protection layer-3, polishing layer-4, polishing agent layer-5, wear-resistant layer-6. DETAILED DESCRIPTION Embodiment 1:

[0021] like Figure 1 As shown, this embodiment proposes: an environmentally friendly breathable reinforced leather, comprising;

[0022] A vegetable tanned natural leather layer 1, wherein the natural leather layer 1 is provided with fine grooves (fine grooves are small scratches, small grooves, etc. produced during tanning, etc.);

[0023] It also includes a permeable protective layer 2, which fills part of the fine grooves and is fixedly arranged on the outside of the natural leather layer 1 {the processing process can be: thoroughly cleaning the vegetable tanned natural leather layer 1 to remove impurities that may remain in the tanning process, and then using natural oils (olive oil or sunflower oil, etc.) or environmentally friendly softeners, etc. to infiltrate and soften the natural leather layer 1, which can not only increase the softness and elasticity of the leather, but also improve its air permeability, and subsequently a thin protective film can be formed on the surface of the natural leather layer 1 to fill part of the fine groove space, and the protective film is the permeable protective layer 2};

[0024] The filling layer 3 fills the fine grooves and is fixedly arranged on the outside of the seepage protective layer 2 {using a filler (usually a water-based or natural material, such as water-based polyurethane, etc.), when arranged on the outside of the seepage protective layer 2, the fine grooves are filled and a protective layer (i.e., the filling layer 3) is formed}. The use of water-based polyurethane is environmentally friendly and can provide good waterproof performance while maintaining a certain air permeability;

[0025] The polishing layer 4 is arranged outside the filling layer 3 {the filling layer 3 is polished (the polishing treatment can use very fine natural or synthetic abrasives, such as fine pumice powder, plant fiber pads or specific environmentally friendly abrasive pads, to gently polish the leather surface to improve the surface flatness) to form the polishing layer 4};

[0026] A polishing agent layer 5 is fixedly attached to the outer side of the polishing layer 4;

[0027] The polishing agent layer 5 is a natural wax layer or the like, which is used to enhance glossiness and water resistance, while also providing additional protection against stains and daily wear and tear, and enhancing aesthetics. Embodiment 2:

[0028] like Figure 1 As shown, the difference between it and embodiment 1 is that it also includes a wear-resistant layer 6, which is fixedly arranged on the outside of the polishing agent layer 5;

[0029] The wear-resistant layer 6 is a nano-scale ceramic coating, etc. The nano-scale ceramic coating will not form a thick covering layer on the surface of the polishing agent layer 5, but will form a very thin and transparent protective film, which will have little impact on the aesthetics of the polishing agent layer 5; at the same time, it will form a more solid and smooth surface, greatly enhancing the protective properties of the leather; the air permeability will be little affected after covering; and it can also provide additional anti-fouling and easy-to-clean properties.

[0030] The above shows and describes the basic principles and main features of the utility model and the advantages of the utility model. For those skilled in the art, it is obvious that the utility model is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic features of the utility model. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive. The scope of the utility model is limited by the attached claims rather than the above description, and it is intended to include all changes within the meaning and scope of the equivalent elements of the claims. Any figure mark in the claims should not be regarded as limiting the claims involved.

[0031] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
