Problems solved by technology

Although the technological process from the gray yarn to the winding drum is relatively short, it takes a long time, and it needs to go through dehydration, drying and other processes during the process, which consumes a lot of water and energy.
In addition, due to the insufficient fluffiness and plumpness of traditional cheese dyed yarn, its level dyeing performance is poor

Embodiment 1

[0025] The carbon dioxide cheese dyeing kettle of the present invention comprises a cylinder body 1 and a cheese support 2; the cheese support 2 is fixed in the cylinder body 1; the upper end of the cylinder body 1 is fixed with a movable sealing cover 3, and the lower end is provided with a carbon dioxide fluid inlet 4, The upper part of the cylinder 1 is also provided with a carbon dioxide fluid outlet 5; a heating jacket 6 is fixed on the outside of the cylinder 1; the upper end of one side of the heating jacket 6 is provided with a heating medium outlet 7, and the lower end of the other side is provided with a heating medium inlet 8. It is characterized in that the cheese support 2 is composed of a distribution site 201, a central axis 203 and six inserts 202; There are 6 inserts 202 distributed; the inserts 202 are movably connected with the distribution site 201, and can rotate freely around the connection; the central axis 203 is a porous shaft structure; the distributio...

Embodiment 2

[0028] Put 3kg of reactive disperse black dye into the dye kettle, and put 90kg of wool cheese into the special support for cheese. Turn on the refrigeration system, when the pressure of the storage tank drops to 4~4.3MPa, the liquid level of the storage tank rises to 425~427mm, and carbon dioxide gas starts to be introduced. Then, turn on the heater and oil pump to heat the temperature to 90-95°C, start the high-pressure pump to pressurize to 22-23 MPa, and dye for 28-31 minutes. After dyeing, turn off the high-pressure pump, heater and oil pump, release the pressure, cool down and keep it at 3~4MPa, 32~34℃ to recover carbon dioxide and dye, and take out the dyed wool cheese. After dyeing, the color fastness to washing of the cheese can reach grade 3, the color fastness to rubbing can reach grade 4, and the color fastness to light and weather can reach grade 4. The color fastness of wool cheese dyed with traditional reactive disperse black dyes is 3-4 grades. After using spe...

Embodiment 3

[0030]Take out 3.5kg of disperse dark blue dye and put it into the dye kettle, put 35kg of cashmere cheese into the special cheese holder, turn on the refrigeration system, reduce the pressure of the storage tank to 4MPa, the liquid level of the storage tank rises to 421-424mm, and start to introduce carbon dioxide gas. Turn on the heating system and raise the temperature to 130-135°C. Turn on the high-pressure pump, increase the pressure to 20-21MPa, and dye for 30-33 minutes. After dyeing, turn off the high-pressure pump and heating system, release the pressure, lower the temperature to 3.5-4MPa, 38-41°C, recover carbon dioxide and dye, and take out the dyed cheese. After dyeing, the color fastness to washing of cheese yarn is grade 4, the color fastness to rubbing is grade 5, and the color fastness to washing can reach grade 4. The color fastness of package yarn dyed with traditional disperse dark blue dyes is 3-4 grades, and the color fastness of cashmere cheese yarn dyed...

Abstract

The invention relates to a supercritical carbon dioxide cheese dyeing kettle and a waterless supercritical carbon dioxide cheese dyeing method. In the dyeing kettle, when carbon dioxide fluid enters a distribution tray from an inlet, blades start rotating clockwise under the effect of pressure; inserted drill rods are driven to rotate by a rotation part; and the rotating speed of the inserted drill rods is increased along with the increase of pressure in a cylinder body. When a cheese is dyed, the cheese on the inserted drill rods is dyed at a speed of 0.2-0.5 r / s. When the rotating cheese is dyed, the cheese is subjected to the pressure of the fluid flowing out from a central shaft; the rotation and bicirculation of the cheese dyeing are realized; the uniform dyeing effect of the dyed cheese can be improved; and the migration ability and the diffusibility can be improved.

Description

technical field [0001] The invention belongs to the field of textile printing and dyeing, and puts wool, cashmere, yak wool, cotton and cotton blended cheese with a certain degree of bulk into a special dyeing kettle for cheese, and performs supercritical carbon dioxide dyeing on the cheese to provide a supercritical cheese suitable for cheese. Critical carbon dioxide staining method. Background technique [0002] Traditional dyeing mainly uses water as the medium. During the dyeing process, a large number of chemical substances such as dyes, auxiliaries and surfactants cause serious pollution to the environment, and also restrict the sustainable development of the textile printing and dyeing industry. In the 21st century, the requirements for easy control, high efficiency, no pollution and recyclability are becoming more and more prominent. The supercritical carbon dioxide anhydrous dyeing technology developed at the end of the last century is considered as a "green and su...
