Problems solved by technology

[0003] The fabrics in the prior art can be waterproof, oil-proof, stain-proof and other dirt while partly maintaining the original fabric characteristics. The technology can be roughly divided into three types: one is to realize waterproof through fiber swelling with water, However, after long-term use, the softness of the fabric will deteriorate, the air permeability will decrease, and the comfort will deteriorate, making it difficult to become the mainstream of the market; the second is to achieve waterproofing through coatings. Aging, severe dirt cannot be thoroughly cleaned, the coating is prone to cracking, and the market share is gradually decreasing; the third is to achieve waterproofing by laminating waterproof membranes, using polytetrafluoroethylene and fabrics for composite lamination, after lamination , the drapability, breathability, softness, fit and lightness of the fabric have a certain loss

Embodiment 1

[0023] In this embodiment, a vacuum nano-waterproof and breathable fabric includes a built-in layer, a fabric substrate, a nano-waterproof layer, and a nano-water-repellent coating from the inside to the outside. The built-in layer and the nano-waterproof layer are respectively laminated on both sides of the fabric substrate by hot pressing. , the nano-water-repellent coating adopts vacuum nano-coating to deposit a thin film on the nano-water-proof layer;

[0024] The fabric base material is one of polypropylene fiber, polyester fiber and regenerated fiber.

[0025] The preparation steps of the vacuum nanometer waterproof breathable fabric are as follows:

[0026] (1) Preparation of built-in layer

[0027] a. Pickle the common polyimide fiber with salicylic acid with concentration percentage of 10-15% for 20-30min, then remove and drain and impregnate with ammonium chloride with concentration percentage of 2-5% for 20-30min , take it out and drain it, put it into a continuou...

Abstract

The invention relates to a vacuum nano waterproof breathable fabric, and belongs to the technical field of fabrics. The vacuum nano waterproof breathable fabric comprises a built-in layer, a cloth base material, a nano waterproof layer and a nano water-repellent plating. The built-in layer and the nano waterproof layer are respectively compounded on the two sides of the cloth base material through hot pressing. The nano water-repellent plating layer is formed by depositing a layer of film on the nano waterproof layer in a vacuum nano coating mode. The built-in layer is formed by weaving modified polyimide fibers and cotton fibers treated by water-repellent finishing liquid. By compounding the built-in layer, the cloth base material, the nano waterproof layer and the nano water-repellent plating layer, the fabric has excellent waterproof and breathable effects and certain softness, and meanwhile, the fabric is anti-static, bacteriostatic and flame-retardant.

Description

technical field [0001] The invention belongs to the technical field of fabrics, and in particular relates to a vacuum nanometer waterproof and breathable fabric and its application. Background technique [0002] From manual production to mechanical production, the progress of equipment and the development of material technology have continuously updated clothing materials and fabrics. With the development of science and technology, textiles have gradually become waterproof, moth-proof, shrink-proof, stain-proof and water-resistant. Inflammability and other properties, thus adding many new functions to clothing, which can be adapted to different environments. [0003] The fabrics in the prior art can be waterproof, oil-proof, stain-proof and other dirt while partly maintaining the original fabric characteristics. The technology can be roughly divided into three types: one is to realize waterproof through fiber swelling with water, However, after long-term use, the softness o...
