Abstract

The invention relates to the field of textile materials, and particularly discloses a preparation method of an anti-ultraviolet and moisture-permeable composite fabric. The preparation method of the anti-ultraviolet and moisture-permeable composite fabric comprises the following steps of S1, taking a composite fabric formed by co-spinning polyurethane and cotton fibers, dipping the composite fabric in a pretreatment solution, carrying out an oscillation reaction, and performing washing with water and and drying to obtain a to-be-treated fabric; S2, taking 40-60 parts by weight of an anti-ultraviolet finishing agent, 10-30 parts by weight of a moisture-permeable finishing agent, 1-10 parts by weight of polyethylene glycol 200, 0.5-2 parts by weight of lithium chloride and 10-15 parts by weight of deionized water, stirring and dispersing the anti-ultraviolet finishing agent, the moisture-permeable finishing agent and the polyethylene glycol 200 firstly, performing heat-preservation stirring, adding the lithium chloride and the deionized water, and performing stirring to obtain a composite finishing agent; S3, putting the to-be-treated fabric into a composite finishing agent solution, carrying out padding treatment, and taking out a finished fabric; and S4, enabling the finished fabric to be pre-baked, baked, washed and naturally aired, so that the anti-ultraviolet moisture-permeable composite fabric is obtained. The anti-ultraviolet and moisture-permeable composite fabric has the advantages of being excellent in anti-ultraviolet performance, elasticity and moisture permeability.

Description

technical field [0001] This application relates to the field of textile materials, more specifically, it relates to a method for preparing an ultraviolet-resistant and moisture-permeable composite fabric. Background technique [0002] With the improvement of social material and cultural living standards, fabrics only have thermal insulation functions are not enough to meet people's needs. In order to meet people's increasingly diverse requirements for textile performance, fabrics are endowed with different functions through different textile technologies; due to Ultraviolet rays are ubiquitous in daily life. A small amount of ultraviolet rays can have beneficial effects on the human body, but a large amount of ultraviolet rays can disturb the immune system and reduce the immune function of the human body. Therefore, most of the existing fabrics are endowed with anti-ultraviolet properties. [0003] Existing anti-ultraviolet finishing agents are generally divided into inorgan...
