[0002] Polyvinyl chloride (PVC) coated cloth is made of glass fiber cloth, glass cotton cloth and chemical fiber cloth as the base cloth, and is coated with a special process. Its main performance characteristics are: waterproof, flame retardant, mildew-proof, cold-proof and corrosion-resistant (referred to as three-proof cloth and five-proof cloth); aging-resistant; UV-resistant; easy to clean; high temperature resistant (180 degrees) and good thermal insulation. Its main uses are tarpaulins and air duct cloths. The former is widely used in tarpaulins for trains and automobile transportation, tarpaulins for grain storage, docks and warehouses, and the latter is widely used in drilling tower covers, various tents, mine air ducts, etc.

[0003] At present, the mine air ducts made of polyvinyl chloride (PVC) coated cloth and glass fiber cloth on the market have excellent waterproof and flame retardant characteristics, but most of them are single-layer structures. Because the surrounding environment where they are laid is mostly uneven rock structures, they are easily penetrated by friction from rock corners during mobile installation. In addition, during subsequent operation and use, the noise reduction and heat insulation effects of the fabric are poor. When the medium flows inside the fabric product, it is easy to affect the surrounding staff. The practical performance needs to be strengthened. Utility Model Content

Because the surrounding environment of the laying use is mostly uneven rock structures, the local area is easily rubbed by the rock corners during mobile installation to form penetrating wounds. In addition, during subsequent operation and use, the noise reduction and heat insulation effect of the fabric is poor. When the medium inside the fabric product flows, it is easy to affect the surrounding staff, and the practical performance needs to be strengthened.

[0007] The noise reduction layer is located on the inner surface of the inner coating layer, the noise reduction layer is connected to the coating layer through an adhesive layer, the inner surface of the noise reduction layer is provided with a soft layer, the inner surface of the soft layer is provided with a heat insulation layer, the heat insulation layer is sewn with the noise reduction layer through sewing thread, and the inner surface of the heat insulation layer is provided with a friction reduction layer.

[0008] Preferably, the soft layer is a honeycomb structure.

[0009] Compared with the prior art, the utility model has the following advantages:

[0010] Through the coordination between the glass fiber cloth, the inner lining layer, the mesh layer and the coating, the mesh layer is first sewn between the two layers of glass fiber cloth, and then the outer surfaces of the two layers of glass fiber cloth are provided with the upper coating, and finally the inner lining layer is provided on the surface of the inner coating, and then the obtained fabric can be processed into products for installation and use. The mesh layer between the two layers of glass fiber cloth has excellent strength, which can effectively resist the impact of heavy objects and the cutting of sharp objects. Combined with the buffering and shock-reducing effect of the soft layer, the fabric products are not prone to penetration damage. In addition, the noise reduction layer and the heat insulation layer can give the fabric products good noise reduction and heat insulation effects. When the medium inside the fabric flows in subsequent use, it is not easy to affect the surrounding staff, and the practical performance of the fabric is enhanced. BRIEF DESCRIPTION OF THE DRAWINGS
