Embodiment 1

[0030] The present invention combines the attached figure 1 And attached figure 2 Be explained.

[0031] The supercritical carbon dioxide hair ball dyeing kettle of the present invention comprises a cylinder body 1 and a hair ball dyeing cylinder body 2, and the hair ball dyeing cylinder body 2 is fixed in the cylinder body 1; The carbon dioxide fluid outlet 4, the upper part of the cylinder body 1 is also provided with the carbon dioxide fluid inlet 5; the outer side of the cylinder body 1 is fixed with a heating jacket 6; There is a heating medium inlet 8; it is characterized in that a central tube 202 is fixed at the center of the hair ball dyeing cylinder 2, and at least one limit upper cover 201 is fixed on the central tube 202; the central tube 202 is a porous shaft structure, the bottom support plate 203 of the cylinder body 2 is provided with a hole I204, and the central hole Ia204a corresponds to the inner cavity of the central pipe 202; the limit upper cover 201 ...

Embodiment 2

[0034]Disperse blue dye 5kg is placed in the dye still of supercritical carbon dioxide dyeing device. Use special equipment (such as an electric hoist), open the lifting ring of the dyeing cylinder in the dyeing kettle of the supercritical carbon dioxide dyeing device, and lift the entire dyeing cylinder; open the dyeing cylinder, and use special equipment (such as a ball forming machine) to pack 50kg hair balls Put it into the dyeing cylinder, place the limit upper cover in the dyeing cylinder to limit the amount of hair balls, and connect with the cylinder through an O-ring, and the position of the O-ring can be placed inside the dyeing cylinder according to needs. Then turn on the refrigeration system, pressurize the liquid carbon dioxide to above the critical pressure, and then heat the high-pressure liquid carbon dioxide to above the critical point temperature through the heat exchanger, that is, the carbon dioxide reaches the critical state. Supercritical carbon dioxide ...

Embodiment 3

[0036] Reactive red dye 4kg is placed in the dye still of supercritical carbon dioxide dyeing device. Use special equipment (such as an electric hoist), open the lifting ring of the dyeing cylinder in the dyeing kettle of the supercritical carbon dioxide dyeing device, and lift the entire dyeing cylinder; open the dyeing cylinder, and use special equipment (such as a ball forming machine) to evenly mix 80kg hair balls Put the cake into the dyeing cylinder after making the cake, place the limit upper cover in the dyeing cylinder to limit the amount of hair balls, and connect with the cylinder through an O-ring, and the position of the O-ring can be placed inside the dyeing cylinder according to needs . Then turn on the refrigeration system, pressurize the liquid carbon dioxide to above the critical pressure, and then heat the high-pressure liquid carbon dioxide to above the critical point temperature through the heat exchanger, that is, the carbon dioxide reaches the critical s...

Abstract

The invention relates to a supercritical carbon dioxide hairball dyeing kettle which comprises a cylinder body and a hairball dyeing barrel body fixed in the cylinder body, wherein a movable sealing cover is fixed at the upper end of the cylinder body, and the lower end of the cylinder body is provided with a carbon dioxide liquid outlet; a carbon dioxide liquid inlet is arranged at the upper part of the cylinder body; a heating clamping sleeve is fixed outside the cylinder body; a heating medium outlet is arranged at the upper end of one side of the heating clamping sleeve, and a heating medium inlet is arranged at the lower end of the other side of the heating clamping sleeve; the supercritical carbon dioxide hairball dyeing kettle is characterized in that a hole III is formed in the wall of the hairball dyeing barrel body; a central pipe is fixed to the centre of the hairball dyeing barrel body, and at least one upper limiting cover is fixed to the central pipe; the central pipe has a multi-pore shaft structure; a hole I is formed in a supporting plate at the bottom of the barrel body; a central hole Ia is corresponding to an internal chamber of the central pipe; and a hole II is formed in the upper limiting cover. According to the supercritical carbon dioxide hairball dyeing kettle increased, the direct contacting surface area of the a hairball and the dyeing liquid can be increased, and improves the influence due to the gravity in hairball dyeing can be improved, and the dyeing speed and the dye pickup can be improved, as well as the dyeing uniformity is improved.

Description

technical field [0001] The invention belongs to the field of textile printing and dyeing, and relates to a supercritical carbon dioxide wool ball dyeing kettle and an anhydrous dyeing method thereof, and more specifically relates to a dyeing kettle suitable for wool ball dyeing in a supercritical carbon dioxide dyeing device. Background technique [0002] The traditional wool top dyeing is to dye the wool top raw material into top balls. When dyeing, the top balls are first strung on the mandrel, the mandrel is put into the dyeing cylinder, and then the dyeing cylinder containing the wool top balls is put into the dyeing kettle for dyeing. After the dyeing is finished, the residual liquid needs to be drained, and the floating color should be removed by washing with water or soaping multiple times. The tops are then dried. Because wool top balls go through multiple processes such as dyeing and cleaning, the fibers in the dried wool top balls are relatively chaotic, and the ...
