Vacuum nano-electroplating waterproof breathable fabric and production process thereof

Abstract

The invention discloses a vacuum nano-electroplating waterproof breathable fabric and a production process thereof. The fabric comprises a fabric base material, a high-density waterproof layer and a nano-water-repellent plating layer, the high-density waterproof layer is combined with the surface of the fabric base material by a hot-pressing and compounding mode, a nano-water-repellent plating layer film is deposited on the high-density waterproof layer by a vacuum nano-film coating mode, and the surface of the nano-water-repellent plating layer can have 10-15 dynes. The fabric is treated by the aid of a vacuum nano-film coating technique, so that the fabric has better waterproof and hydrophobic functions, original characteristics (heat retention, breathability, comfort, portability and the like) of the fabric can be effectively kept, nano-scale film coating is implemented, dosage of materials is less, the fabric can be prepared from low-cost materials and has the advantages of low cost, adverse by-products are omitted in the whole treatment process, the fabric is green and environmentally friendly, and film layers are stable and not easy to decompose.

Description

technical field [0001] The invention relates to the technology in the field of waterproof materials, in particular to a vacuum nano-electroplated waterproof and breathable fabric and its production process. Background technique [0002] The progress of textiles from manual production to mechanical production and the development of material technology have made clothing materials constantly updated. With the development of science and technology, textiles have been endowed with properties such as waterproof, mothproof, shrinkproof, antifouling and flame retardant, thus adding many new functions to clothing. With the development of the times and the progress of science, the aesthetic consciousness and knowledge structure of consumers have changed, and the various demands of consumers for clothing are also constantly changing. People hope that clothing fabrics can resist water, oil, dirt and other dirt, while maintaining their original use and comfort characteristics. [0003...

AI Technical Summary

Problems solved by technology

Although the waterproof and moisture permeability of PTFE fabrics is better than other fabrics, due to its own chemical inertness, the film is difficult to be degraded by nature, and the combustion temperature is as high as 405°C. Large-scale applications make GORE-TEX gradually become a killer of the environment.

Today's low-carbon green environmental protection has become the consensus of the international community. The environmental protection of GORE-TEX will be the bottleneck of its development, but its washing fastness still needs to be improved. If it is not compounded with a hydrophilic film, the washing fastness is generally only 5 times or so

At the same time, after lamination, the drapability, breathability, softness, fit and lightness of the fabric will be lost to a certain extent.
