Problems solved by technology

Because high-shrinkage yarns are all filaments with high boiling water shrinkage performance, the overall yarn shrinkage after processing improves weaving performance and fabric compactness, but because there is no filament length difference, the lotus leaf effect is relatively small. Poor, it will affect the water repellency effect, and the water pressure resistance is also limited; in addition, the bulkiness is not enough

Abstract

The invention discloses waterproof and moisture permeable fabrics and a production method thereof. Yarns of at least one type of the warp direction and the weft direction of the waterproof and moisture permeable fabrics are formed by composite filaments which are formed by spontaneous elongation filaments A and high shrinkage filaments B; the sum of covering coefficients of the warp direction and the weft direction of the waterproof and moisture permeable fabrics is more than 2700; the waterproof pressure in the preliminary stage is more than 1000 mmH2O; the moisture permeability is more than 3500 g / m<2>.d. The waterproof and moisture permeable fabrics are plump and soft in touch, comprise a certain body, are comfortable to wear and good in windproof and rainproof function and are ideal materials for sports and leisure.

Description

technical field [0001] The invention relates to a waterproof and moisture-permeable textile and a production method thereof. It specifically relates to a kind of high-density fabric formed by using special composite yarn, which can obtain a waterproof and moisture-permeable fabric with superior performance without coating or laminating processing, and can be dyed in dark colors, and has good environmental protection performance. Background technique [0002] Due to the improvement of living standards, people's requirements for the wearability of textiles are getting higher and higher. [0003] In particular, the requirements for environmental protection and functionality are getting higher and higher. Among them, waterproof and moisture-permeable fabrics have become the basic demands of sportswear and outdoor sportswear. [0004] At present, waterproof and moisture-permeable fabrics on the market mainly have two methods of coating and bonding. This kind of fabric has long ...
