Waterproof and breathable chemical fiber cloth

Abstract

The invention discloses waterproof and breathable chemical fiber cloth which comprises a chemical fiber fabric layer. A nonwoven layer is arranged on the lower surface of the chemical fiber fabric layer, a plurality of convex blocks in matrix distribution are arranged on the upper surface of the chemical fiber fabric layer, each convex block is of a cuboid structure, a PU layer is connected on theupper surface of the chemical fiber fabric layer in a pressed manner, a plurality of protrusions in matrix distribution are arranged on the lower surface of the PU layer, each protrusion is semispherical and is connected on four corresponding convex blocks in a pressed manner, and diameter L1 of each protrusion is smaller than the sum of space L2 between each two adjacent convex blocks and side length L3 of the corresponding convex block; a passage with two longitudinal ends thin and middle thick is penetratingly arranged on the PU layer, section of the passage is S-shaped, and the bottom ofthe passage is positioned at the center of the bottom end of each protrusion. The chemical fiber cloth has high waterproof and breathable performance and high wear resistance and 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.
