[0019] The method for preparing moisture-absorbing quick-drying cotton fabric of the present invention comprises the following steps:

[0020] (1) Glyoxal, silane coupling agent, penetrating agent, sodium bicarbonate, magnesium chloride and water are mixed to obtain the first finishing solution, the first finishing solution is padded with cotton fabric, rolled up, at 60- Stack at 80°C for 5-48 hours, then wash and dry;

[0021] (2) Mixing the hydrophilic softener and water to obtain a second finishing solution, padding the cotton fabric obtained after the treatment in step (1) with the second finishing solution, and then drying and baking.

[0022] In the method of the present invention, in the first finishing liquid, the concentration of the glyoxal can be 30-100g / L, preferably 50-80g / L; the concentration of the silane coupling agent is 3-20g / L, preferably 5-10g / L; the concentration of the penetrant can be 10-40g / L, preferably 20-30g / L; the concentration of the sodium bicarb...

Embodiment 1

[0033] (1) Mix glyoxal, vinyltriethoxysilane, penetrant NR, sodium bicarbonate, magnesium chloride and water to prepare the first finishing liquid, wherein the concentration of glyoxal is 65g / L, ethylene The concentration of triethoxysilane is 8g / L, the concentration of penetrant NR is 25g / L, the concentration of sodium bicarbonate is 12g / L, and the concentration of magnesium chloride is 8g / L. The cotton fabric was soaked twice and rubbed with the first finishing liquid, the squeeze rate was controlled to 65%, coiled, stacked at 70° C. for 24 hours, and then washed and dried.

[0034] (2) Add the hydrophilic softener SYNICO-6811 into water to prepare the second finishing liquid, wherein the concentration of the hydrophilic softener SYNICO-6811 is 50 g / L. Then, it was dried at 85° C. for 2 minutes, and then baked at 150° C. for 3 minutes to obtain finished cotton fabric A1.

Embodiment 2

[0036] (1) Mix glyoxal, vinyltrimethoxysilane, penetrant NR, sodium bicarbonate, magnesium chloride and water to prepare the first finishing liquid, wherein the concentration of glyoxal is 50g / L, vinyl The concentration of trimethoxysilane is 5g / L, the concentration of penetrant NR is 30g / L, the concentration of sodium bicarbonate is 8g / L, and the concentration of magnesium chloride is 6g / L. The cotton fabric was soaked twice and rubbed twice with the first finishing liquid, the squeeze rate was controlled to 60%, coiled, stacked at 60° C. for 48 hours, and then washed and dried.

[0037] (2) Add the hydrophilic softener SYNICO-6811 into water to prepare the second finishing liquid, wherein the concentration of the hydrophilic softener SYNICO-6811 is 40 g / L. Then, it was dried at 90° C. for 1 minute, and then baked at 140° C. for 5 minutes to obtain finished cotton fabric A2.

Abstract

The invention relates to the technical field of textile printing and dyeing processing, and discloses a method for preparing a moisture-absorbing quick-drying cotton fabric. The method comprises the following steps of (1) mixing glyoxal, a silane coupling agent, a penetrating agent, sodium bicarbonate, magnesium chloride and water to obtain first finishing liquid, padding the cotton fabric into the first finishing liquid, rolling, piling for 5-48 hours at the temperature of 60-80 DEG C, and then washing and drying; and (2) mixing a hydrophilic softening agent and water to obtain second finishing liquid, padding the cotton fabric treated in the step (1) into the second finishing liquid, and then drying and baking. The cotton fabric obtained after finishing according to the method disclosedby the invention has better moisture absorption and quick drying performance and hydrophilicity.

Description

technical field [0001] The invention relates to the technical field of textile printing and dyeing, in particular to a method for preparing moisture-absorbing and quick-drying cotton fabrics. Background technique [0002] In recent years, with the improvement of the quality of life, people's pursuit of fitness and shaping has become higher and higher, and more and more athletes are engaged in outdoor activities. Sports enthusiasts prefer natural fiber clothing, especially pure cotton fabrics, which are soft Comfortable, natural and eco-friendly, easy care and long-lasting durability are the favorites. However, when the human body sweats a lot, the cotton fiber will swell due to moisture absorption, the fiber cross section will increase by 40-50%, the fabric will become tight, and the pores will be blocked, hindering the heat exchange between the microclimate between the skin and the clothing and the external environment. Exchange and moisture exchange, and the cotton fiber ...
