Embodiment 1

[0042] (1) Mix acrylate, penetrant NR, maleate, ammonium persulfate and water to prepare the first finishing solution, wherein the concentration of acrylate is 50g / L, and acrylate is dimethyl methacrylate A mixture of amino ethyl ester, hydroxyethyl methacrylate and methyl methacrylate, the mass ratio of the three is 1:1:1, the concentration of penetrant NR is 25g / L, and the concentration of maleate is 12g / L L, the concentration of ammonium persulfate 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 50° C. for 24 hours, then washed with water and dried.

[0043] (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

[0045](1) Mix acrylate, penetrant NR, fumarate, ammonium persulfate and water to prepare the first finishing solution, wherein the concentration of acrylate is 40g / L, and acrylate is dimethyl methacrylate A mixture of amino ethyl ester, hydroxyethyl methacrylate and methyl methacrylate, the mass ratio of the three is 1:0.8:1.2, the concentration of penetrant NR is 30g / L, and the concentration of fumarate is 8g / L L, the concentration of ammonium persulfate is 6g / L. The cotton fabric was soaked twice and rubbed with the first finishing liquid, the squeeze rate was controlled to 60%, coiled, stacked at 40° C. for 48 hours, then washed with water and dried.

[0046] (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.

Embodiment 3

[0048] (1) Acrylate, penetrant NR, itaconate, ammonium persulfate and water are mixed to obtain the first finishing solution, wherein the concentration of acrylate is 60g / L, and acrylate is dimethyl methacrylate A mixture of amino ethyl ester, hydroxyethyl methacrylate and methyl methacrylate, the mass ratio of the three is 1:1.2:0.8, the concentration of penetrant NR is 20g / L, and the concentration of itaconate is 15g / L L, the concentration of ammonium persulfate is 10g / L. The cotton fabric was soaked twice and rubbed with the first finishing liquid, the squeeze rate was controlled to 70%, coiled, stacked at 60° C. for 12 hours, then washed with water and dried.

[0049] (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 60 g / L. Then, it was dried at 75° C. for 3 minutes, and then baked at 160° C. for 1 minute to obtain finished cotton fabric A3.

Abstract

The invention relates to the technical field of textile printing and dyeing, and discloses a method for preparing moisture-absorbing and quick-drying cotton fabrics with internal and external hydrophobic and hydrophilic structures from acrylate. The method comprises the following steps: (1) mixing acrylate, penetrating agent, unsaturated acid salt, persulfate and water to prepare the first finishing solution; (2) padding the cotton fabric with the first finishing solution , rolled up, stacked at 40-60°C for 5-48 hours, then washed and dried; (3) mixing the hydrophilic softener with water to prepare the second finishing solution; (4) mixing the step (2 ) padding the second finishing liquid obtained by padding, then drying and baking. The cotton fabric obtained after finishing according to the method of 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 with internal and external hydrophobic and hydrophilic structures from acrylate. 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 ...
