The invention discloses a supercritical carbon dioxide shell button dyeing kettle and a dyeing process thereof. The dyeing kettle includes a kettle body, and the bottom of the kettle body is respectively provided with a carbon dioxide fluid and a dye inlet and a carbon dioxide fluid and a dye outlet. When dyeing, the carbon dioxide fluid and the dye at the bottom flow into the kettle body, impact the buttons and drive the buttons to dye in a non-static manner. , so that the buttons move under the variable speed impact of the airflow, avoiding the dyeing defects at the overlap of buttons. At the same time, the bottom of the barrel of the dyeing kettle of the present invention is designed as an inverted trapezoidal structure to prevent the button from being in contact with the carbon dioxide fluid carrying the disperse dye and thus unable to be dyed. By adopting the dyeing process of the present invention, buttons with rich and complete colors can be obtained, and the dyed products do not need post-processing such as washing and drying, so that the whole process of anhydrous dyeing is realized, production costs are saved, dyeing quality is improved, and environmental pollution is reduced.
Description
technical field [0001] The invention belongs to the technical field of textile printing and dyeing, and relates to a supercritical carbon dioxide dyeing kettle, in particular to a supercritical carbon dioxide shell button dyeing kettle and a dyeing process thereof. Background technique [0002] my country is a country with a shortage of water resources, and the environment of water resources is also deteriorating. Coupled with the waste of water, the situation of water resources is not optimistic. The traditional water-bath dyeing of buttons mainly uses water as the medium. During the dyeing process, a large amount of chemical substances such as dyes, auxiliary agents and surfactants cause serious pollution to the environment. Masterbatch causes instability in the production process of buttons, which restricts the sustainable development of the garment accessories industry. In the 21st century, the requirements for easy control, high efficiency, no pollution and recyclabili...
