Technical Field

[0001] The utility model relates to the technical field of fabrics, in particular to a stain-resistant polyester fiber waterproof fabric. Background Art

[0002] Polyester fiber fabric is a synthetic fiber obtained by spinning polyester formed by the condensation of organic dibasic acids and diols. Industrially mass-produced polyester fiber is made of polyethylene terephthalate. Polyester fiber has high strength, its fabric is strong and durable, and has good wear resistance. It is second only to nylon among synthetic fibers and is higher than other fibers. In addition, its strength remains basically unchanged in wet state.

[0003] Prior art includes a utility model with publication number CN220314427U. The utility model discloses an anti-wrinkle polyester fiber fabric. The utility model comprises: a polyester fabric base, wherein the polyester fabric base is provided with a skin-friendly layer on the side closest to the user, and an anti-wrinkle layer and an elastic layer in sequence on the other side; the elastic layer is connected and fixed to the outer surface of the anti-wrinkle layer by elastic fiber yarns; a first air permeability array is provided on the polyester fabric base; a plurality of anti-deformation balls are provided in an array between the anti-wrinkle layer and the elastic layer, and second air permeability holes are provided between two adjacent anti-deformation balls. The polyester fabric of the utility model uses the polyester fabric base as the fabric body and has the advantages of high strength; the design of the air permeability makes it breathable; the combination of the anti-wrinkle layer and the elastic layer on the outer surface of the polyester fabric base allows the fabric to rebound when wrinkled, and the elastic layer covering the anti-deformation balls not only enhances the stability of the fabric under impact, but also has good resilience of the anti-deformation balls, thereby improving the overall wrinkle resistance of the fabric, thereby solving the problem that existing all-polyester fabrics often have a simple structure and are prone to wrinkling.

[0004] In daily work, it is found that the existing polyester fiber fabrics have poor overall waterproof and anti-fouling effects during use. Polyester fiber fabrics are easily soaked by water and easily stained with stains such as oil stains, mud, etc. The stains not only affect the appearance but are also difficult to clean, resulting in the poor overall anti-fouling and waterproof effects of the existing polyester fiber fabrics. Utility Model Content

[0005] The utility model aims to solve the shortcomings of the prior art in that the anti-fouling and waterproof effects are poor, and proposes an anti-fouling polyester fiber waterproof fabric.

[0006] In order to achieve the above-mentioned purpose, the present invention adopts the following technical scheme: a kind of anti-fouling polyester fiber waterproof fabric, comprising a polyester fiber fabric layer and a protective device, the surface of the polyester fiber fabric layer is provided with a protective device, the protective device comprises a first glue bonding layer, a waterproof functional layer, a second glue bonding layer, and an anti-fouling functional layer, the first glue bonding layer, the waterproof functional layer, the second glue bonding layer, and the anti-fouling functional layer are sequentially arranged on the surface of the polyester fiber fabric layer from bottom to top, the waterproof functional layer is bonded to the polyester fiber fabric layer through the first glue bonding layer, the anti-fouling functional layer is bonded to the waterproof functional layer through the second glue bonding layer, the waterproof functional layer comprises a waterproof base layer, an anti-penetration coating is provided above the waterproof base layer, a plurality of water guide grooves are provided on the surface of the waterproof base layer, the anti-fouling functional layer comprises an anti-adhesion layer, and a plurality of micro-convex hemispheres are provided above the anti-adhesion layer.

[0007] Preferably, the bottom of the water guide groove is inclined toward both sides. Through the above components, the water guide groove with the bottom inclined toward both sides can better guide away moisture and improve the waterproof effect.

[0008] Preferably, the anti-penetration coating is made of polytetrafluoroethylene material, and the anti-penetration coating is evenly coated on the waterproof base layer. Through the above components, the anti-penetration coating made of polytetrafluoroethylene has extremely low surface energy and can form a dense and stable waterproof film on the surface of the fabric. It has excellent waterproof performance, and it is difficult for water droplets to adhere to its surface, which can effectively prevent moisture penetration.

[0009] Preferably, the anti-adhesion layer is made of perfluoroalkoxy polymer material. Through the above components, it has excellent chemical corrosion resistance and anti-fouling properties, and also has a certain flexibility and can adapt to the bending and stretching of the fabric.

[0010] Preferably, the diameter of the micro-convex hemispheres can be about 200nm to 5μm. When the stain contacts the material surface through the above components, the contact between these micro-convex hemispheres and the stain is point contact or local contact, which greatly reduces the actual contact area between the stain and the material surface.

[0011] Compared with the prior art, the advantages and positive effects of the present invention are:

[0012] 1. In the utility model, the anti-adhesion layer made of perfluoroalkoxy polymer material has excellent chemical corrosion resistance and anti-fouling properties through the anti-fouling functional layer. At the same time, a plurality of micro-convex hemispheres are arranged on the top of the anti-adhesion layer, which can make point contact or local contact with the stains, greatly reducing the actual contact area between the stains and the material surface, and can effectively prevent the stains from firmly adhering to the material surface, thereby improving the anti-fouling performance of the fabric.

[0013] 2. In the present invention, by setting a waterproof functional layer, the anti-penetration coating made of polytetrafluoroethylene is evenly coated on the waterproof base layer and the water guide groove in the waterproof base layer. It has extremely low surface energy and can form a dense and stable waterproof film on the surface of the fabric. It has excellent waterproof performance, and it is difficult for water droplets to adhere to its surface, which can effectively prevent moisture penetration. The bottom of the water guide groove is inclined to both sides, which can better drain water and effectively improve the overall waterproof and anti-penetration performance of the fabric.
