Supercritical carbon dioxide garment dyeing kettle and waterless dyeing method thereof

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...

AI Technical Summary

Problems solved by technology

[0003] At present, in the dyeing kettle of the supercritical carbon dioxide dyeing device, the garment fabric is wound on the dyeing frame to realize the dyeing process of the supercritical carbon dioxide fluid to the garment. Due to certain defects in the existing garment dyeing device, the contact area between the dye liquor and the garment fabric is uneven. Difficult loading and unloading before and after dyeing; and cannot guarantee the level dyeing of white blank garments during dyeing, etc.
