Technical Field

[0001] The utility model relates to the technical field of breathable fabrics, in particular to a waterproof and oil-proof breathable fabric. Background Art

[0002] In clothing production, the quality of clothing depends largely on the type and quality of the selected fabric. In order to ensure that the product has good breathability and waterproof properties, a waterproof and breathable fabric is usually used.

[0003] After searching, the published application number CN202321541243.7 mentioned a microporous waterproof and breathable fabric, which includes: a protective layer, the surface of the protective layer is densely covered with breathable holes, the fabric selected for the protective layer is bamboo fiber, the lower end of the protective layer is distributed with waterproof blocks, the waterproof blocks are water-absorbent, pores are left between the waterproof blocks, and water-absorbent resin is provided inside the waterproof blocks. An anti-corrosion layer is provided on the lower surface of the protective layer, and the raw material used for the anti-corrosion layer is polytetrafluoroethylene. By providing a waterproof block with a water-absorbent resin on the lower surface of the protective layer, when the fabric comes into contact with moisture, it penetrates the waterproof layer into the interior of the waterproof block and is absorbed by the water-absorbent resin, thereby achieving the effect of protecting the inner layer and waterproofing. At the same time, pores are left between the waterproof blocks to maintain the breathability of the fabric.

[0004] However, the above-mentioned breathable fabric still has the following disadvantages: although the above-mentioned breathable fabric has the effect of being waterproof and breathable, it does not have the oil-proof function, so that oil stains are easily adhered to the breathable fabric, affecting the aesthetics of the breathable fabric.

[0005] Therefore, it is necessary to design a waterproof, oil-proof and breathable fabric to solve the above-mentioned problems. Utility Model Content

[0012] As a preferred solution of the present invention, the middle support layer is made of fluorine fiber material.

[0013] As a preferred solution of the present invention, the fabric base layer is woven from the same fabric as the breathable fabric.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] In the utility model, a waterproof, oil-proof and breathable fabric is provided. The breathable fabric first adopts a first waterproof layer and a second waterproof layer to achieve the waterproof effect of the breathable fabric, and the oil-proof effect of the breathable fabric can be achieved by the first oil-proof layer and the second oil-proof layer, thereby achieving the waterproof and oil-proof performance of the breathable fabric; and the intermediate support layer provided in the middle position of the breathable fabric can support the entire breathable fabric, thereby providing the stability of the breathable fabric.
