Problems solved by technology

[0003] Although good waterproof performance can be obtained after waterproof coating finishing, directly setting the coating on the fabric will greatly reduce the air permeability of the fabric, and the hand feel is poor. The coating peels off, and the waterproof performance is not long-lasting

Abstract

The invention provides a preparation method of a waterproof and breathable water sportswear fabric, and belongs to the field of functional fabric preparation. The water sportswear fabric comprises a surface layer prepared from a waterproof and breathable fabric, and the waterproof and breathable fabric is formed by interweaving waterproof and breathable fibers as warp yarns and weft yarns; the preparation method of the waterproof and breathable fabric comprises the following steps of S1, doping nano-zinc oxide or nano-titanium oxide into polymer resin, and spinning into fibers; S2, conducting KH570 surface active site modification; S3, grafting a methacrylic acid hydrophilic monomer; S4, grafting an azobenzene segment; and S5, grafting a hydrophobic segment; and then manufacturing into a fabric. The fibers are subjected to graft modification and then interwoven into the fabric, the breathability of the fabric can be kept while the waterproof performance is obtained, and a hydrophilic segment, a photosensitive heterogeneous segment and the hydrophobic segment are sequentially grafted to the resin fibers through graft modification to construct the hydrophilic-hydrophobic reversible conversion waterproof fabric.

Description

technical field [0001] The invention relates to the field of preparation of functional fabrics, in particular to a waterproof and breathable water sportswear fabric and a preparation method thereof. Background technique [0002] Modern people pay more and more attention to improving the quality of life, and outdoor water sports have become a hobby of life after work. In the process of outdoor water sports, in addition to good sweat absorption, breathability and elasticity, the clothing fabrics worn are also required to have waterproof performance. The common method is to carry out waterproof coating on the fabrics to obtain waterproof performance. [0003] Although good waterproof performance can be obtained after waterproof coating finishing, directly setting the coating on the fabric will greatly reduce the air permeability of the fabric, and the hand feel is poor. The coating peels off and the waterproof performance is not durable. Contents of the invention [0004] I...
