Problems solved by technology

However, the existing cotton fabric moisture absorption and quick-drying finishing technology usually makes the cotton fabric form a hydrophobic outer surface, which will inevitably reduce the hydrophilicity of the cotton fabric, thus affecting the wearing comfort of cotton fabric clothing.

preparation example Construction

[0019] The method of preparing a moisture absorbing carcass fabric according to the present invention includes the following steps:

[0020] (1) Mix the ethylene arralant, silane coupling agent, penetrant, sodium bicarbonate, magnesium chloride, and water to obtain the first finishing liquid, impregnate the first finishing liquid, tap, in 60- 80 ° C is stacked 5-48 hours, then washed, dry;

[0021] (2) Mix the hydrophilic softener and water to obtain a second finishing liquid, and the cotton fabric obtained after proceeding by step (1) is subjected to the second finishing liquid, and then dried and bake.

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

Embodiment 1

[0033] (1) Mix the ethylene arralant, vinyl triethoxysilane, penetrant NR, sodium bicarbonate, magnesium chloride, and water, and produce the first finishing liquid, wherein the concentration of ethylene arralase is 65 g / L, ethylene The concentration of the base triethoxysilane is 8 g / L, the concentration of the penetrant NR is 25 g / L, the concentration of sodium bicarbonate is 12 g / L, and the concentration of magnesium chloride is 8 g / L. The cotton fabric doshed tween rolled the first finishing solution, the control rolling rate was 65%, and the plate was piled up at 70 ° C for 24 hours, then washed, dried.

[0034] (2) The hydrophilic softener Synico-6811 was added to water, and the second finishing liquid was produced, wherein the hydrophilic softener SynicO-6811 had a concentration of 50 g / L. Then dry at 85 ° C for 2 minutes, then bake at 150 ° C for 3 minutes, thereby obtaining a cotton fabric A1 after finishing.

Embodiment 2

[0036] (1) Mix the ethylene arralant, vinyl trimethoxysilane, penetrant NR, sodium bicarbonate, magnesium chloride, and water, and produce the first finishing liquid, wherein the concentration of ethylene arralans is 50 g / L, vinyl The concentration of trimethoxysilane was 5 g / L, and the concentration of the penetrant NR was 30 g / L, the concentration of sodium bicarbonate was 8 g / L, and the concentration of magnesium chloride was 6 g / L. The first finishing liquid is rolled with the cotton fabric, and the control rolling rate is 60%, the roll, and is piled up at 60 ° C for 48 hours, then washed, dried.

[0037] (2) The hydrophilic softener Synico-6811 was added to the water, and the second finishing liquid was produced, wherein the hydrophilic softener Synico-6811 had a concentration of 40 g / L. It was then dried at 90 ° C for 1 minute, then baked at 140 ° C for 5 minutes, thereby obtaining a cotton fabric A2 after finishing.

Abstract

The invention relates to the technical field of textile printing and dyeing processing, and discloses a method for preparing moisture-absorbing and quick-drying cotton fabrics. The method comprises the following steps: (1) mixing glyoxal, silane coupling agent, penetrating agent, sodium bicarbonate, magnesium chloride and water to obtain a first finishing solution, padding the cotton fabric with the first finishing solution, Roll up, stack at 60-80°C for 5-48 hours, then wash and dry; (2) Mix the hydrophilic softener and water to obtain the second finishing solution, which will be obtained after the treatment in step (1) padding the second finishing solution on the cotton fabric, 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 present invention relates to the field of textile printing and dyeing, and more particularly to a method of preparing a moisture absorbent cascad fabric. Background technique [0002] In recent years, with the quality of life, people are increasingly pursuit of fitness and shaping, more and more athletics engaged in outdoor activities, and sports enthusiasts tend to natural fiber clothing, especially cotton fabrics, soft Comfortable, natural and environmentally friendly, simple nursing, durable, and favored. However, when the body dishink is large, cotton fiber will expand due to moisture, the fiber cross section is increased by 40-50%, and the fabric becomes close, the pores are blocked, and the microstructure between the skin and the clothes and the external environment. Exchange and wet exchange, and cotton fiber water absorption and water retention rate are large, sweat, and the sweat is difficult to quickly discharge, thereby producing a hot sense....
