Embodiment 1

[0030] The present invention is described in conjunction with the accompanying drawings.

[0031] The supercritical carbon dioxide garment dyeing kettle of the present invention comprises a cylinder body 1 and a garment dyeing cylinder body 2, and the garment dyeing cylinder body 2 is fixed in the cylinder body 1; the upper end of the cylinder body 1 is equipped with a movable sealing cover 9, and the lower end is provided with a carbon dioxide fluid Outlet 3, the upper part of the cylinder body 1 is provided with a carbon dioxide fluid inlet 4; the outside of the cylinder body 1 is fixed with a heating jacket 5; the upper end of one side of the heating jacket 5 is provided with a heating medium outlet 6, and the lower end of the other side is provided with a heating medium Inlet 7; it is characterized in that the cylinder wall of the garment dyeing cylinder 2 is provided with a hole I8; the center of the bottom support plate 10 of the garment dyeing cylinder 2 is fixed with an...

Embodiment 2

[0034] Disperse red 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 out the entire dyeing cylinder; open the dyeing basket, and move 10 polyester-cotton blended white T-shirts and polyester blanks 15 pairs of trousers and 15 woolen silk scarves, about 20kg in total, are evenly loaded into the dyeing basket. 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 enters the dye kettle pre-installed with dye, and the supercritical fluid with dye passes through the dye kettle to make the device reach the target process...

Embodiment 3

[0036] Reactive blue 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 basket, and put 20 pieces of polyester sweaters, 30 pieces of pure cotton sports pants, 30 wool knitted scarves and 25 pairs of nylon elastic stockings, about 40kg in total, are evenly loaded into the dyeing basket. 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 enters the dye kettle pre-installed with dye, and the supercritical fluid with dye passes through the dye kettle to make the device reac...

Abstract

The invention relates to a supercritical carbon dioxide garment dyeing kettle. The supercritical carbon dioxide garment dyeing kettle comprises a cylinder body and a garment dyeing barrel body, wherein the garment dyeing barrel body is fixed in the cylinder body; a movable sealing cover is installed at the upper end of the cylinder body, a carbon dioxide fluid outlet is arranged at the lower end of the cylinder body, and a carbon dioxide fluid inlet is arranged at the upper part of the cylinder body; a heating jacket is fixedly arranged on the outer side of the cylinder body; and a heating medium outlet is arranged at the upper end of one side of the heating jacket, and a heating medium inlet is arranged at the lower end of the other side of the heating jacket. The supercritical carbon dioxide garment dyeing kettle is characterized in that an area distributor is fixedly arranged at the center of a support plate at the bottom of the garment dyeing barrel body, and divides the garment dyeing barrel body into three areas, namely, a clothes rack area I, a trousers rack area II and an ornament rack area III; a hole is formed in the support plate at the bottom of the garment dyeing barrel and the diameter of the hole is corresponding to the hole diameter of the cylinder body. According to the supercritical carbon dioxide garment dyeing kettle, the influence on degradation factors of fluid flow in the garment dyeing can be improved, and the dyeing uniformity and the dye-uptake can be improved.

Description

technical field [0001] The invention belongs to the field of textile printing and dyeing, and relates to a supercritical carbon dioxide dyeing kettle and an anhydrous dyeing method thereof, in particular to a dyeing kettle suitable for garment dyeing in a supercritical carbon dioxide dyeing device. Background technique [0002] Garment dyeing refers to the process of sewing gray fabrics or semi-finished products that have been pre-scoured and bleached into garments and then dyeing them. Most of the garment dyeing is to dye the semi-finished fabrics after scouring and bleaching into white blank garments. The production cycle of garment dyeing is short, so it can well adapt to the fast-paced and changing clothing industry, and is more and more popular in the market. However, the garment dyeing at the present stage still stays on the traditional dyeing method. After the dyeing is finished, the residual liquid needs to be drained and washed with multiple channels of clear water...
