Supercritical carbon dioxide horn button dyeing kettle and its dyeing process

Abstract

The invention discloses a supercritical carbon dioxide ox horn button dyeing kettle and a dyeing technology. The dyeing kettle comprises a kettle body. A carbon oxide fluid and dye inlet and a carbon oxide fluid and dye outlet are formed in the bottom of the kettle body; during the dying, the carbon oxide fluid and dye flow into the kettle body from the bottom to impact the button and drive the button to dye in a non-static way, so the button can move due to air flow impact; and dying flaws of overlapped parts between buttons can be avoided. The cylindrical bottom of the dyeing kettle is in an inverted trapezoidal structure to enable the buttons to have contact with carbon oxide fluid with dying paint and finish dying. Buttons with rich colors can be acquired by the use of the dying technology; dyed products require no cleaning and drying operations; a water-free dying process is achieved; production cost is reduced; and dying quality is improved and environment 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 horn 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 recyclabilit...
