Background

Waterproof and breathable textiles are the targets which are pursued by people all the time, and are more needed in modern society life, and have the capability of dissipating sweat exhausted by human bodies to the surrounding environment through the textiles, namely breathability and waterproofness. Along with the development of economy and the continuous improvement of living standard, people have higher and higher requirements on the performance of living goods, and the waterproof breathable fabric gradually enters the life of people due to the excellent waterproof and breathable performances. Waterproof breathable fabrics are widely applied to fashionable backpacks, fashionable clothes and hats and even various protective clothing and are popular with people.

However, most of the existing waterproof breathable fabrics only have a layer of waterproof breathable film arranged on the outer surface of the textile fabric, which is used for waterproof and breathable performance of the textile fabric, so that once the waterproof breathable film is damaged, the textile fabric loses the waterproof effect, for example, patent document with application number of CN201610618874.2 discloses a waterproof breathable fabric and a preparation method thereof, wherein a waterproof layer is arranged at the upper end of a substrate layer, and waterproof performance is realized by utilizing the characteristic of water absorption and expansion of a water absorption and expansion material; moreover, most of the existing waterproof breathable fabrics lack an antibacterial function, once the fabric is used for too long, too many bacteria are bred in the fabric, and the health of a user can be seriously harmed, for example, patent document with application number of CN201810495244.X discloses a waterproof breathable fabric and a preparation method thereof, and no antibacterial layer is arranged in the fabric.
