Problems solved by technology

[0002] Most of the existing fabrics are dyed by exhaust dyeing. This method consumes a lot of water, and it is necessary to reduce the hardness and turbidity of the printing and dyeing water to prevent the water quality from affecting the printing and dyeing effect. After dyeing, the fabric needs to be fixed and dyed. Rinsing, drying and other processes to complete the printing and dyeing, the process is complicated and the cost is high, even if the water is treated, the metal ions contained in it may still affect the color of the fabric

Embodiment 1

[0012] Put the dye into the pressure tank 1, then inject carbon dioxide into the pressure tank with a high-pressure pump, heat to 40°C after the pressure reaches 7.3MPa, continue to inject carbon dioxide until the pressure is 20MPa, at this time the carbon dioxide is in a supercritical state, stir evenly. The fabric is sent to the dyeing area at a speed of 100 m / min by the mesh conveyor belt through the conveying device 4 (the dyeing area is between the atomization chamber 2 and the vacuum system 3), and the vacuum system 3 is turned on, and the vacuum degree of the vacuum system is -0.04 MPa, open valve 5 at the same time, pump the dye and carbon dioxide in the pressure tank into the atomization chamber, when the atomization chamber sprays out, because the pressure of carbon dioxide drops from 20MPa to below 1 atmospheric pressure instantly, it has a certain effect on the dye in the carbon dioxide medium The blasting effect makes the atomized particles very fine and uniform, a...

Embodiment 2

[0014] The difference from Example 1 is that the temperature in the pressure tank is 50° C. and the pressure is 25 MPa.

Abstract

The invention discloses a printing and dyeing method for a fabric. The method comprises the following steps: contacting one surface of the fabric with an atomizer chamber and the other surface of the fabric with a vacuum system; dispersing a dye into a supercritical carbon dioxide medium; then injecting the dye into the atomizer chamber for atomization; and starting the vacuum so as to allow the atomized dye to be adsorbed by the fabric. According to the invention, the supercritical carbon dioxide medium is used; a water treatment step before printing and dyeing and subsequent procedures like dye fixation and rinsing are not needed, which enables the process to be simplified; compared to particles obtained through atomization in an aqueous medium, particles obtained through atomization in the supercritical carbon dioxide medium are more uniform and finer, and the fabric obtained in the invention has a more brilliant color.

Description

technical field [0001] The invention belongs to the field of textile printing and dyeing, and in particular relates to a vacuum printing and dyeing method for cloth. Background technique [0002] Most of the existing fabrics are dyed by exhaust dyeing. This method consumes a lot of water, and it is necessary to reduce the hardness and turbidity of the printing and dyeing water to prevent the water quality from affecting the printing and dyeing effect. After dyeing, the fabric needs to be fixed and dyed. Rinsing, drying and other processes to complete printing and dyeing are complicated and costly. Even if the water is treated, the metal ions contained in it may still affect the color of the fabric. Contents of the invention [0003] The object of the present invention is to provide a non-aqueous medium cloth printing and dyeing method. [0004] The technical scheme adopted by the present invention to realize the above object is as follows: [0005] A cloth printing and d...
