The utility model relates to the technical field of waterproof cloth, and discloses novel waterproof flag cloth which comprises a base cloth layer, a waterproof layer made of PU (polyurethane) materials is fixedly adhered to one side face of the base cloth layer, an elastic stretching layer is fixedly arranged on the other side face of the base cloth layer, and the elastic stretching layer is arranged on the base cloth layer. A second hydrophobic layer is sprayed on the outer side surface of the elastic stretching layer and is used for improving the tension of the water surface and reducing the permeability of water to the cloth, and the base cloth layer is made of a chinlon fabric. The chinlon fabric and the spandex fabric layer are compounded, so that the strength and the toughness of the fabric are good, the fabric serving as a flag fabric is stiff and not prone to deformation, edges and threads are not prone to being opened and scattered in strong wind, and in addition, the compact waterproof layer and the chemical waterproof coating are arranged, so that the outer surface of the fabric is kept clean and cannot permeate and absorb water.

Description

Technical Field

[0001] The utility model relates to the technical field of waterproof cloth, in particular to a novel waterproof flag cloth. Background Art

[0002] Fabric is a commonly used material in decoration, including chemical fiber carpets, non-woven wall cloths, linen, nylon, colored tape, flannel and other fabrics. Fabric plays a considerable role in decorative display and is often the main force that cannot be ignored in the entire sales space. The extensive use of fabric for wall decoration, partitions, and background processing can also form a good commercial space display style. From the weaving method, it can be divided into two categories: woven fabric and knitted fabric. From the processing technology, it can be divided into: grey cloth, bleached cloth, dyed cloth, printed cloth, yarn-dyed cloth, mixed process cloth (such as printing on yarn-dyed cloth, composite cloth, flocking cloth, imitation fur cloth), etc. It can also be divided according to raw materials: cotton cloth, chemical fiber cloth, linen, woolen cloth, silk, and blended fabrics, etc.

[0003] In the prior art, when fabrics are used outdoors on rainy days, the fabrics come into contact with rainwater, which makes the fabrics susceptible to penetration, resulting in low waterproof performance, and rainwater easily adheres to the surface, resulting in reduced practical effects of the fabrics. Therefore, a waterproof fabric is proposed. Utility Model Content

[0004] The technical problem to be solved by the utility model is: in order to overcome the above problems, a new waterproof flag cloth is provided, which solves the above problems.

[0005] The utility model solves the technical problem by adopting the following technical solutions:

[0006] A novel waterproof flag cloth comprises a base cloth layer, a waterproof layer made of PU material is glued and fixed on one side of the base cloth layer, an elastic stretch layer is fixed on the other side of the base cloth layer, and a second hydrophobic layer is sprayed on the outer side of the elastic stretch layer to increase the water surface tension and reduce the permeability of water to the cloth, and the base cloth layer is made of nylon fabric.

[0007] Preferably, in order to improve the high temperature resistance of the fabric, a polytetrafluoroethylene coating is sprayed on the outer surface of the base fabric layer so that it can maintain good strength under high-intensity sunlight.

[0008] Preferably, in order to improve the ductility of the fabric and reduce its brittleness after oxidation, an elastic stretch layer is fixedly provided on any single side of the base fabric layer.

[0009] Preferably, the elastic stretch layer is a spandex fabric layer, which is fixed to the back side of the base fabric layer provided with the waterproof layer by gluing.

[0010] Preferably, a hydrophobic coating is provided on the outer wall surface of the waterproof layer to improve the anti-rainstorm and waterproof performance of the waterproof layer.

[0011] Preferably, the waterproof layer is a layer of silicon dioxide nano waterproof coating.

[0012] The advantages and positive effects of the utility model are as follows: the composite of nylon fabric and spandex fabric layer makes the fabric have good strength and toughness, and is strong and not easy to deform as flag fabric, and is not easy to open edge and loose thread in strong wind; in addition, the dense waterproof layer and chemical waterproof coating are provided, so that the outer surface of the fabric is kept clean and will not penetrate and absorb water.
