Abstract

Genuine leather pile face polyurethane leather comprises a base cloth (1), an electrostatic flocking genuine leather fibrous layer (2) arranged on the front face of the base cloth, an electrostatic flocking genuine leather fibrous layer (3) arranged on the back face of the base cloth, and a polyurethane surface layer (4) arranged on the surface of the genuine leather fibrous layer (2) on the front face of the base cloth. The genuine leather pile face polyurethane leather provides a genuine leather feeling on both front and back face, wherein the front layer surface has strong stereoscopic sensation like the surface of first layer leather, the back layer surface has a fluff feeling like a genuine leather back, and the cutting surface of the leather is also similar with the first-layer leather. In addition, the product has a flavor of genuine leather, thereby achieving highly artificial effect.

Description

Corium matte polyurethane leather

Technical field

The utility model relates to a kind of structure of synthetic leather, a kind of corium matte polyurethane leather.

Background technology

Existing synthetic leather is that the coated with resins surface layer forms on cloth matter base material, in order to the outward appearance of imitation corium, is difficult to the skin emulation effect that reaches good.The kind of flocked leather that proposes of Chinese patent application 92112133.4 for example is to be base material with the PVC artificial leather of washing one's face, and tow manually becomes mildewed on leather surface is planted; The flocking simulated leather that Chinese patent application 92111405.2 proposes is to be base material with the pattern synthetic leather, plants fibre fluff in its dermatoglyph the lowest point.The fine hair that these kind of flocked leather are planted is neither to be corium powder fine hair, with corium bigger difference is arranged eventually.

Summary of the invention

The utility model is intended to propose a kind of skin emulation effect structure of good synthetic leather especially, a kind of corium matte polyurethane leather.

This corium matte polyurethane leather comprises base cloth, and there is the corium fabric layer of one deck electrostatic spinning in the front of base cloth, and also there is the corium fabric layer of one deck electrostatic spinning at the back side of base cloth, also has one deck polyurethane surface layer on the surface of the corium fabric layer in front.

This corium matte polyurethane leather positive and negative all has the sense of touch of corium, and the sense of face-coating surface three-dimensional is strong, is similar to the surface of first layer lether, there is the fine hair sense at the corium back side at the back side, the cut surface of leather is also close with first layer lether, and product has the fragrance of corium, reaches the effect of high emulation.

Description of drawings

Accompanying drawing is the structural representation of this corium matte polyurethane leather.

The specific embodiment

As shown in the figure, this corium matte polyurethane straw bag is drawn together base cloth 1, there is the corium fabric layer 2 of one deck electrostatic spinning in the front of base cloth, and also there is the corium fabric layer 3 of one deck electrostatic spinning at the back side of base cloth, also has one deck polyurethane surface layer 4 on the surface of the corium fabric layer 2 in front.

Product of the present utility model is a kind of real leather intimating synthetic leather that flocking method is combined and makes with the synthetic leather polyurethane coating.Its manufacture method is: 1, the leftover pieces with corium are ground into particle; 2, the corium particle is dyeed; 3, with the method for electrostatic spinning the corium particle is adhered to two surfaces of base cloth 1, the corium particle of one side is thinner, and another side is thicker, and thin one side is as the front; 4, the electrostatic spinning layer is polished, increase the fiber effects of corium face; 5, one side that the corium particle is thinner is carried out sanding and is handled, and then with the method composite polyurethane surface layer that dry method shifts, perhaps uses method coated one deck polyurethane surface layer of roller coat.Through the surface layer of the transfer coated processing of dry method, can reflect the irregular lines that exposes the corium matte; Through the surface layer that roller coat is handled, expose the fine hair of corium in the slit of lines, soft, reach the effect that is similar to corium.

Base cloth in this corium matte polyurethane leather can be that cotton can be chemical fabrics such as terylene, viscose, nylon also, and its weaving mode can be knitted cloth or Woven Fabrics, also can be nonwoven fabric.

Claims

1. corium matte polyurethane leather, comprise base cloth (1), there is the corium fabric layer (2) of one deck electrostatic spinning in the front of base cloth, also there is the corium fabric layer (3) of one deck electrostatic spinning at the back side of base cloth, it is characterized in that also having one deck polyurethane surface layer (4) on the surface of the corium fabric layer (2) in front.
