Waterproof and gas-permeable chemical fiber cloth

Abstract

The invention discloses a waterproof and gas-permeable chemical fiber cloth, which comprises a chemical fiber fabric layer, wherein the lower surface of the chemical fiber fabric layer is provided with a non-woven fabric layer, a plurality of projection blocks distributed in a matrix are arranged on the upper surface of the chemical fiber fabric layer, the projection block is a square structure, aPU layer is pressed and connected on the upper surface of the chemical fiber fabric layer, a plurality of projections distributed in a matrix are arranged on the lower surface of the PU layer, the projection is hemispherical, and is pressed and connected on the four projection blocks corresponding to the projection, the diameter L1 of the projection is smaller than the sum of the distance L2 between the adjacent projection blocks and the side length L3 of the projection block, a longitudinal channel with both thin ends and thick middle portion penetrates through the PU layer, the cross section of the channel is S-shaped, and the bottom portion of the channel is positioned at the center of the bottom end of the projection. According to the present invention, the waterproof and gas-permeable chemical fiber cloth has characteristics of good water resistance, good gas permeability, good wear resistance and good tear resistance.

Description

technical field [0001] The invention relates to a chemical fiber product, in particular to a waterproof and breathable chemical fiber cloth. Background technique [0002] The textile industry is the pillar industry of our country. A large amount of cloth is sold all over the world every year. As people change the style, performance and place of use of cloth, cloth with various functions is also emerging. Nowadays, with the increase in the number of outdoor sports and leisure travel, people are more fond of cloth and clothing with special functions. The requirements of these clothing for the cloth are that the outer layer is waterproof, wear-resistant, the inner layer is soft, the overall breathability, and warmth retention. But now Some soft and breathable fabrics are mostly pure cotton textile products. Although they are light in weight, soft and smooth on the surface, suitable for wearing next to the skin, they have poor waterproof performance, no abrasion resistance, and ...

Nowadays, with the increase in the number of outdoor sports and leisure travel, people are more fond of cloth and clothing with special functions. The requirements of these clothing for the cloth are that the outer layer is waterproof, wear-resistant, the inner layer is soft, the overall breathability, and warmth retention. But now Some soft and breathable fabrics are mostly pure cotton textile products. Although they are light in weight, soft and smooth on the surface, suitable for wearing next to the skin, they have poor waterproof performance, no abrasion resistance, and poor tear resistance.
