Drawings
Fig. 1 is a schematic structural view of the present invention;
description of reference numerals: 1. the anti-static fabric comprises a non-woven fabric layer, 2, a first reinforced net layer, 3, an anti-ultraviolet fabric layer, 4, a waterproof layer, 5, a second reinforced net layer, 6, an anti-static layer, 7 and a flexible layer.
Detailed Description
The present invention will be further explained with reference to the accompanying drawings:
referring to figure 1: in the embodiment, the compound leather base fabric comprises a non-woven fabric layer 1, wherein the non-woven fabric layer 1 has good heat insulation performance, low cost and excellent cold and hot air heat insulation effect, a first reinforced net layer 2 is arranged on the top of the non-woven fabric layer 1, an ultraviolet-proof fabric layer 3 is arranged on the top of the first reinforced net layer 2, a waterproof layer 4 is arranged on the top of the ultraviolet-proof fabric layer 3, a second reinforced net layer 5 is arranged on the bottom of the non-woven fabric layer 1, an antistatic layer 6 is arranged on the bottom of the second reinforced net layer 5, and a flexible layer 7 is arranged on the bottom of the antistatic layer 6. Leather base cloth is by waterproof layer 4 in proper order, anti ultraviolet layer 3, first reinforcement net surface layer 2, non-woven fabrics layer 1, second reinforcement net surface layer 5, antistatic backing 6 and flexible layer 7 are compound to be constituteed, these surface fabrics mutually support and obtain a high performance's leather base cloth material, not only have better waterproof, anti ultraviolet, thermal-insulated and prevent performances such as static, and it is high to have very high tensile strength, can effectively resist vertical and horizontal tear powerful, the life of leather base cloth has been increased, and the surface is smooth and stiff and good, can be used for making products such as protective clothing, case and bag, umbrella, tent, the usage is very extensive.
The non-woven fabric layer 1 and the flexible layer 7 are solidified and formed through a needling process, so that the non-woven fabric layer 1 and the flexible layer 7 are firmer and more compact, and have the function of mutual lamination and reinforcement.
The first reinforcing net layer 2 and the second reinforcing net layer 5 are woven by polyester yarns, the thickness of the net surface is 0.2-0.5mm, and the diameter of meshes on the net surface is 3-5 mm. The polyester yarns are rich in elasticity, can bear large tensile force, can reinforce the non-woven fabric layer 1, avoid loosening and tearing of the non-woven fabric layer, are extremely high in fire resistance, and can improve the fire resistance of the leather base fabric.
The waterproof layer 4 is composed of a Thermoplastic Polyurethane (TPU) film and a natural rubber film. The thermoplastic polyurethane TPU film is positioned on the inner layer, has the characteristics of water resistance, high elasticity, softness and the like, can effectively prevent moisture from invading the cloth, and the natural rubber film is positioned on the surface layer, so that the thermoplastic polyurethane TPU film not only has the characteristics of excellent rebound resilience, insulativity, water resistance, plasticity and the like, but also has the performances of oil resistance, acid resistance, alkali resistance, wear resistance and the like, and can be used for protecting the thermoplastic polyurethane TPU film.
The ultraviolet-proof fabric layer 3 is composed of a bamboo charcoal fiber woven layer and a glass fiber woven layer. The glass fiber woven layer is located the upper strata of bamboo charcoal fiber woven layer, can block the ultraviolet ray that the wavelength is less than 300nm more than 90%, and bamboo charcoal fiber woven layer is to take mao bamboo as the raw materials, and the calcination preparation that is delayed through pure oxygen high temperature and nitrogen gas separation forms, and its unique fiber structure design has characteristics such as antibacterial, green and anti ultraviolet, has fine blocking and weakening effect to UVA that the wavelength is between 350 ~ 300 nm.
The anti-static layer 6 is formed by weaving carbon black conductive fibers. The carbon black conductive fiber is obtained by carbonizing polyacrylonitrile fiber, and the main chain of the fiber is mainly carbon atoms, so that the fiber has conductive capacity, good conductivity and durability, and particularly good durable antistatic property under low humidity.
The flexible layer 7 is woven by polyurethane fibers, the polyurethane fibers are also called spandex, and synthetic fibers prepared by dry spinning or wet spinning by taking polyurethane as a raw material have high elastic recovery rate and high elongation at break similar to those of rubber yarns, can meet the requirement of comfort, and have good mildew resistance and detergent resistance.
While the invention has been shown and described with reference to a preferred embodiment, it will be understood by those skilled in the art that various changes in form and detail may be made therein without departing from the scope of the appended claims.
