Description

Polyurethane leather

Technical Field

The utility model relates to a leather technical field especially relates to a polyurethane leather.

Background

The artificial leather is made up by using various PVC and PU with different formulas and making them pass through the processes of foaming or film-covering treatment on the basis of textile fabric base or non-woven fabric base, and can be made up according to the requirements of different strength, colour, gloss and pattern, etc. it possesses the characteristics of extensive design and variety, good water-proofing property, neat edge and width, high utilization rate and low cost. PU artificial leather is the skin of polyurethane composition. The natural leather is widely applied to the decoration of bags, clothes, shoes, vehicles and furniture, is increasingly determined by the market, has wide application range, large quantity and multiple varieties, and cannot be met by the traditional natural leather.

The existing PU leather has poor wrinkle resistance, the condition of wrinkle abrasion can be generated when the PU leather is folded, and meanwhile, the leather does not have antibacterial capability, so that the breeding of bacteria is easily caused.

SUMMERY OF THE UTILITY MODEL

The utility model aims at solving the defects existing in the prior art and providing polyurethane leather.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

the utility model provides a polyurethane leather, includes the PU layer, the fixed surface is connected with the TPE layer under the PU layer, the fixed surface is connected with the waterproof layer under the TPE layer, the fixed surface is connected with cold-proof layer under the waterproof layer, cold-proof layer and waterproof layer and TPE layer's thickness ratio are 2.5: 1: 1.2, the antibacterial layer is adhered to the lower surface of the thermal insulation layer.

Preferably, the lower surface of the bacteriostatic layer is fixedly connected with a sweat absorbing layer, the lower surface of the sweat absorbing layer is fixedly connected with an anti-static layer, a plurality of air holes are formed in the anti-static layer at equal intervals, and the air holes are communicated with the sweat absorbing layer.

Preferably, the diameter of the air holes is 0.3 mm.

Preferably, the bacteriostatic layer comprises a bamboo charcoal fiber layer, and the lower surface of the bacteriostatic layer is fixedly connected with a nano-silver coating.

The utility model provides a pair of polyurethane leather, beneficial effect lies in: the design of TPE has strengthened the elasticity of leather and the ability of anti fold, and the design of waterproof layer plays waterproof purpose to leather inside, prevents inside getting into the leather of moisture, and the antibacterial characteristics of disinfecting play in the design on antibacterial layer prevents bacterial growing, and the design of sweat-absorbing layer and bleeder vent is convenient for absorb the sweat, has strengthened the gas permeability of leather.

Drawings

FIG. 1 is a schematic structural view of a polyurethane leather proposed by the present invention;

FIG. 2 is a schematic structural diagram of an antibacterial layer.

In the figure: PU layer 1, TPE layer 2, waterproof layer 3, sweat absorbing layer 4, bleeder vent 5, antistatic layer 6, cold-proof layer 7, antibacterial layer 8, bamboo charcoal fiber layer 81, nano-silver coating 82.

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. 1-2, a polyurethane leather, including PU layer 1, PU layer 1 is made by polyurethane resin material, high strength has, tear-resistant, wear-resisting characteristics, the tensile spirit ability of leather has been strengthened, PU layer 1 lower fixed surface is connected with TPE layer 2, TPE layer 2 is made by thermoplastic elastomer material, high strength has, the characteristics of high resilience, the elasticity of leather has been strengthened, prevent that the leather from taking place the fold, cause the damage of leather, TPE layer 2 lower fixed surface is connected with waterproof layer 3, waterproof layer 3 is made by rubber materials, play waterproof purpose, rubber materials has elasticity simultaneously, be convenient for fold the leather.

Waterproof layer 3 lower fixed surface is connected with cold-proof layer 7, and cold-proof layer 7 layer is made by cotton fiber, has cold-proof function, and the thickness ratio of cold-proof layer 7 and waterproof layer 3 and TPE layer 2 is 2.5: 1: 1.2, it has antibacterial layer 8 to paste on 7 lower surfaces on cold-proof layer, antibacterial layer 8 lower fixed surface is connected with sweat absorbing layer 4, 4 lower fixed surface is connected with antistatic backing 6 on the sweat absorbing layer, antistatic backing 6 is made by the antistatic surface fabric of blending, the antistatic ability of the leather of improvement, prevent to produce static, cause harm to the human body, a plurality of bleeder vents 5 have been seted up equidistant on antistatic backing 6, bleeder vent 5 is linked together with sweat absorbing layer 4, the diameter of bleeder vent 5 is 0.3mm, sweat absorbing layer 4 is made by flax fiber, good moisture absorption gas permeability has, be convenient for absorb the sweat, the gas permeability of leather has been strengthened, bleeder vent 5's design, play ventilative effect, the sweat absorbing layer 4 of being convenient for absorbs the sweat.
