Description

Plant fiber PU leather

Technical Field

The utility model relates to a leather correlation goods field specifically is a plant fiber PU leather.

Background

Natural leather is widely used for producing daily necessities and industrial products due to its excellent natural characteristics, but with the increase of the world population, the demand of human beings for leather is multiplied, and the demand of people cannot be met by the limited amount of natural leather for a long time. To overcome this conflict, various improvements and discoveries have been made, first of all in the substrate, followed by modification and improvement of the coating resin. In the 70 s of the 20 th century, the non-woven fabrics of synthetic fibers have the processes of needling web formation, bonding web formation and the like, so that the base materials have lotus root-shaped sections and hollow fiber shapes, and the porous structure is achieved, thereby meeting the requirements of the mesh structure of natural leather; the surface layer of the synthetic leather can already be a polyurethane layer with a micro-pore structure, which is equivalent to the grain surface of natural leather, so that the appearance and the internal structure of the PU synthetic leather are gradually close to those of the natural leather. However, the heat-insulating and breathable effects of natural leather cannot be achieved in artificial PU leather.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a plant fiber PU leather to solve the problem that proposes among the above-mentioned background art.

In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a plant fiber PU leather, includes the base cloth layer, one side fixedly connected with fibrous layer of base cloth layer, one side fixedly connected with waterproof layer of base cloth layer is kept away from to the fibrous layer, the ventilative layer of one side fixedly connected with of fibrous layer is kept away from to the waterproof layer, one side fixedly connected with upper epidermis that the waterproof layer was kept away from to ventilative layer.

Preferably, the fiber layer is a bamboo fiber fabric layer, and the thickness is 0.4-0.5 mm.

Preferably, the waterproof layer is a silicon oil layer, and the thickness of the waterproof layer is 0.2-0.3 mm.

Preferably, a plurality of ventilation micropores are arranged on the ventilation layer.

Preferably, the upper surface layer is a mesh fabric layer, and the thickness of the mesh fabric layer is 1-2 mm.

Compared with the prior art, the beneficial effects of the utility model are that:

this plant fiber PU leather makes it possess antibacterial antibiotic, moisture absorption ventilative, green's characteristics through set up the fibrous layer that the one deck comprises bamboo fiber precoat on the base cloth layer, sets up the waterproof layer on the fibrous layer and can effectively play waterproof performance, and the waterproof layer adopts the silicon oil layer can improve the feeling of surface fabric, and a plurality of ventilative micropores on ventilative layer can have better ventilation effect, the utility model discloses a setting up of multilayer structure can make this plant fiber PU leather wholly absorb moisture more ventilative, has better ventilation effect.

Drawings

Fig. 1 is the structure schematic diagram of the plant fiber PU leather of the utility model.

In the figure: 1-base cloth layer, 2-fiber layer, 3-waterproof layer, 4-breathable layer and 5-upper surface layer.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.

Referring to fig. 1, the present invention provides an embodiment: the utility model provides a plant fiber PU leather, includes base cloth layer 1, one side fixedly connected with fibrous layer 2 of base cloth layer 1, and fibrous layer 2 keeps away from one side fixedly connected with waterproof layer 3 of base cloth layer 1, and waterproof layer 3 keeps away from ventilative layer 4 of one side fixedly connected with of fibrous layer 2, and ventilative layer 4 keeps away from one side fixedly connected with upper epidermis 5 of waterproof layer 3.

Further, the fiber layer 2 is a bamboo fiber fabric layer with the thickness of 0.4-0.5 mm.

Further, the waterproof layer 3 is a silicon oil layer with a thickness of 0.2-0.3 mm.

Further, the air-permeable layer 4 is provided with a plurality of air-permeable micropores.

Further, the upper surface layer 5 is a mesh fabric layer with the thickness of 1-2 mm.

The working principle is as follows: firstly, set up fibrous layer 2 that the one deck comprises bamboo fiber precoat on base cloth layer 1 and make it possess antibacterial antibiotic, moisture absorption ventilative, green's characteristics, set up waterproof layer 3 on fibrous layer 2 and can effectively play waterproof performance, waterproof layer 3 adopts the silicon oil layer can improve the feel of surface fabric, and a plurality of ventilative micropores on ventilative layer 44 can have better ventilation effect.

It is obvious to a person skilled in the art that the invention is not restricted to details of the above-described exemplary embodiments, but that it can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.
