description of reference numerals: 1. the base cloth layer 2, the antistatic layer 3, the soft elastic layer 4, the fireproof layer 5, the antibacterial polyester layer 6, the fluff layer 7 and the flame-retardant waterproof coating layer.

Detailed Description

The present invention will be further explained with reference to the accompanying drawings:

referring to figure 1: the antibacterial sofa leather base cloth comprises a base cloth layer 1, wherein an antistatic layer 2 is arranged on the base cloth layer 1, a soft elastic layer 3 is arranged on the antistatic layer 2, a fireproof layer 4 is arranged on the soft elastic layer 3, an antibacterial polyester layer 5 is arranged on the fireproof layer 4, a fluff layer 6 is arranged on the antibacterial polyester layer 5, and a flame-retardant waterproof coating layer 7 is coated on the fluff surface of the fluff layer 6. The sofa leather base cloth is formed by compounding six different fabric layers and one coating layer, so that the sofa leather base cloth has certain strength and also has the functions of static resistance, fire prevention and bacteria resistance; the anti-static layer 2 arranged on the base cloth layer 1 endows the sofa leather base cloth with the conductivity, so that the sofa leather base cloth has good anti-static property; the soft elastic layer 3 is made of a sponge layer double-sided knitted spandex fiber weaving layer, the fireproof layer 4 is arranged on the soft elastic layer 3, so that the sofa leather base cloth has good rebound resilience and flame retardance at the same time, the comfort and the safety of the sofa leather base cloth are improved, in addition, the fluff layer 6 on the surface layer of the sofa leather base cloth has good skin-friendly performance, the antibacterial polyester layer 5 at the bottom can avoid bacteria breeding at the bottom of the fluff layer, and the antibacterial polyester layer 5 is formed by weaving antibacterial polyester filaments; titanium dioxide nano particles are embedded in the inner surface of the antibacterial polyester filament yarn woven into the antibacterial polyester layer 5; the flame-retardant waterproof coating layer 7 is coated on the surface of the fluff layer, so that the fluff layer has high temperature resistance and water washing resistance, and the safety and sanitation of the sofa leather base cloth are further improved.

The base cloth layer 1 is composed of a non-woven fabric layer, an adhesive layer and a gauze layer. The non-woven fabric layer is produced by adopting polyester fiber and polyester fiber materials and is manufactured by a needling process, can be made into different thicknesses, handfeels and hardnesses, and has the characteristics of moisture resistance, flexibility, lightness, thinness, flame retardance, no toxicity, no smell, environmental protection and the like. The non-woven fabric layer and the gauze layer are fixedly bonded through the reticular viscose layer. The gauze layer is formed by weaving all yarns, is transparent, thin and loose cloth, has good air permeability and filtering performance, and can be used for sizing and shaping the non-woven fabric layer.

The flame-retardant waterproof coating layer 7 is made of polyurethane foaming adhesive, and the thickness of the flame-retardant waterproof coating layer is 0.02mm-0.06 mm. The polyurethane foaming glue is a product formed by cross-combining an aerosol technology and a polyurethane foam technology, a special polyurethane product is prepared by filling components such as a polyurethane prepolymer, a foaming agent, a catalyst and the like into a pressure-resistant aerosol can, and generated foam can be adhered and solidified on the surface of fluff.

The fireproof layer 4 is made of fireproof cotton layer double-sided knitted glass fiber braided layers. The fireproof layer 4 has the characteristics of good tensile force, good rebound resilience, light weight, softness, difficult deformation after washing, strong heat retention, strong fireproof performance and the like. The main raw material of the fireproof cotton material is formed by combing, lapping and molding polyester fiber and mixing the low-melting-point bonding fiber. The fire-proof agent such as chlorine and bromine is added in the material formula, so that the sponge can generate fire-extinguishing dense smoke when in fire, and the flame-retardant effect is achieved. The glass fiber woven layer can further enhance flame retardancy and tensile resistance.

The antistatic layer 2 is made of flame-retardant conductive silica gel foam, is an electronic material manufactured according to the flame-retardant foam encapsulated by conductive cloth, has good shielding performance, has excellent conductive performance, has the actual flame-retardant effect of the flame-retardant foam, and shows a large amount of maintenance for electronic products. The conductive foam has outstanding shielding performance and conductive performance, can reasonably shield radio waves due to the shielding performance, can block the influence of external radio waves and the release of a radiation source, and also has the effect of durable electrostatic induction safety protection.

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.
