Moisture-absorbing quick-drying fabric and preparation method thereof

Abstract

The invention provides moisture-absorbing quick-drying fabric and a preparation method thereof. The fabric comprises a hydrophilic inner layer and a quick-drying outer layer, wherein the hydrophilic inner layer is composed of bottom yarn, the quick-drying outer layer is composed of surface yarn, the bottom yarn is combed cotton yarn or twisted yarn of the combed cotton yarn and polyester filamentyarn, the surface yarn is special-shaped superfine denier polyester filament yarn, and the D value and the F value in specification of the bottom yarn are both larger than those in specification of the surface yarn. The preparation method of the fabric comprises the steps that the bottom yarn and the surface yarn are woven into gray fabric, and then after-treatment is carried out on the fabric toobtain the moisture-absorbing and quick-drying fabric; wherein the fabric after-treatment comprises alkali treatment and softening treatment; alkali treatment conditions are as follows: a 1wt.%-2wt.%sodium hydroxide solution is adopted, the bath ratio is 1:50, and the treatment is carried out at 90-100 DEG C for 30-40 minutes; softening treatment conditions are as follows: a silicon-free softening finishing agent is adopted, dipping is performed for 20-30 min at the temperature of 20-30 DEG C, then drying is performed for 3-4 min at the temperature of 100 DEG C, and finally baking is performed for 1-2 min at the temperature of 170-180 DEG C. The fabric has excellent moisture-absorbing and quick-drying properties and good durability.

Description

technical field [0001] The invention belongs to the technical field of textiles, and in particular relates to a moisture-absorbing and quick-drying fabric and a preparation method thereof. Background technique [0002] With the progress of the times and the improvement of people's living standards and quality, people have higher and higher requirements for the comfort of clothing fabrics. The comfort of clothing includes two aspects of physiological comfort and psychological factors. Most synthetic fibers lack good water absorption and moisture absorption properties. Under high temperature and high humidity, the human body will feel stuffy and irritated when wearing synthetic fiber fabrics; at the same time, under the hot and humid state, the friction between the human body and the clothes increases, and the feeling of heaviness increases. The increase will cause discomfort to people's physiology and psychology. Traditional clothing fabrics are mostly cotton fabrics, which...

Problems solved by technology

Therefore, the function of moisture-absorbing and quick-drying fabrics needs to go through the processes of wetting, moisture absorption, diffusion and evaporation in sequence. The hygroscopicity can be effectively improved by modifying and grafting hydrophilic groups and roughening the fiber surface, but the existence of a large number of hydrophilic groups is difficult. adversely affect the evaporation rate
