Embodiment 1

[0011] A high moisture-permeable waterproof fabric, comprising a breathable fabric layer and a waterproof breathable layer, the waterproof breathable layer is a microporous polyurethane film, the polyurethane film is a fluorine monomer water-based polyurethane film, and the micropore diameter is 0.2 microns; the breathable fabric The layer is woven by warp threads and weft threads. The weft threads include first weft threads and second weft threads. The first weft threads and the second weft threads are arranged in a ratio of 2:1. The first weft threads are moisture-wicking fibers that absorb moisture and sweat The fiber is covered with smart gel, which is 2-acrylamide-2-methylpropanesulfonic acid, which is grafted and polymerized into the moisture-absorbing and sweat-wicking fiber by Ar microwave plasma-induced graft polymerization; The second weft is a blended fiber of ramie fiber and Lisai fiber, and the percentage by weight of ramie fiber and Lisai fiber blended weaving is ...

Abstract

The invention discloses a high-moisture-permeability waterproof fabric. The invention aims to provide a high-moisture-permeability waterproof fabric which comprises an air-permeable fabric layer and a waterproof air-permeable layer. The waterproof air-permeable layer is a microcellular polyurethane film which is a fluorine monomer waterborne polyurethane film. The air-permeable fabric layer is formed by weaving warp wires and weft wires. The weft wires contain first weft wires and second weft wires which are arranged according to the ratio of 2:1. The first weft wires are moisture-adsorbing and sweat-removing fiber, and the second weft wires are ramie / Richcel fiber blended fiber. The warp wires are tencel fiber / viscose blended fiber. The air-permeable fabric layer and the waterproof air-permeable layer are glued together through a PU adhesive. The fabric of the invention has a simple structure and soft and warm texture, and is beneficial to remove sweat for human body. Waterproof and sweat-removing properties of the fabric can be maintained for a long time.

Description

technical field [0001] The invention relates to a textile fabric, in particular to a high moisture-permeable waterproof fabric. Background technique [0002] Waterproof and moisture-permeable fabric is also called "breathable fabric". It is a fabric that combines waterproof, moisture-permeable, windproof and thermal performance after PU coating or lamination. It can not only resist the invasion of rain and cold wind, but also Let the sweat and sweat of the human body be discharged in time, so as to keep the human body dry and warm and comfortable. With the development of various textile technologies and the expansion of the field of clothing, in recent years, waterproof and moisture-permeable fabrics have made a lot of new progress in technology, and the performance of clothing is becoming more and more perfect, but there are still many problems, such as the structure of the fabric is too complicated; The materials used are too old and traditional; the cost of the design is...
