Abstract

The present application relates to the field of textile materials, and specifically discloses a method for preparing an anti-ultraviolet and moisture-permeable composite fabric. The preparation steps of the anti-ultraviolet and moisture-permeable composite fabric include: S1. Impregnating the composite fabric co-spun with spandex and cotton fibers in a pre- In the treatment solution, shake reaction, wash with water, and dry to obtain the fabric to be treated; S2, in parts by weight, take 40-60 parts of anti-ultraviolet finishing agent, 10-30 parts of moisture-permeable finishing agent and 1-10 parts of polyethylene 200 diols, 0.5-2 parts lithium chloride and 10-15 parts deionized water, first stir and disperse the anti-ultraviolet finishing agent, moisture permeable finishing agent and polyethylene glycol 200, keep stirring, add lithium chloride and deionized water water, stirring to obtain a composite finishing agent; S3, placing the fabric to be treated in the composite finishing agent solution, padding treatment, and taking out the finishing fabric; S4, pre-baking, baking, washing, and naturally drying the finishing fabric to obtain Anti-ultraviolet and moisture-permeable composite fabric; the anti-ultraviolet and moisture-permeable composite fabric of the present application has the advantages of anti-ultraviolet performance, excellent elasticity, and excellent moisture permeability.

Description

technical field [0001] The present application relates to the field of textile materials, and more particularly, to a preparation method of a UV-resistant and moisture-permeable composite fabric. Background technique [0002] With the improvement of social material and cultural living standards, fabrics with thermal insulation functions are no longer enough to meet people's needs. In order to meet people's increasingly diverse requirements for textile properties, different functions are given to fabrics through different textile technologies; Ultraviolet rays are everywhere in daily life. A small amount of ultraviolet rays can have beneficial effects on the human body, but a large amount of ultraviolet rays will disturb the immune system and reduce the immune function of the human body. Therefore, most of the existing fabrics are endowed with UV resistance. [0003] The existing anti-ultraviolet finishing agents are generally divided into inorganic anti-ultraviolet finishing...
