Abstract

The invention relates to a system for color-changeable engineered supercritical carbon dioxide fluid anhydrous dyeing and finishing and a method thereof and belongs to the technical field of dyeing and finishing. The system comprises a dyeing and finishing unit, a separation kettle and a particle on-line detector. The dyeing and finishing unit comprises at least one group of dyeing and finishing kettles, pumps and adsorption kettles. An outlet I of each group of dyeing and finishing kettles is connected with an inlet I thereof through the respective pump, an outlet II of each group of dyeing and finishing kettles is connected with the separation kettle through the respective adsorption kettle, an outlet of the separation kettle is connected with a three-way valve inlet through the particle on-line detector, and a three-way valve outlet I is connected with the separation kettle. Multi-color multifunctional dyeing production of textiles is implemented through the plurality of dyeing and finishing kettles, and color change in supercritical carbon dioxide fluid anhydrous dyeing production is implemented.

Description

technical field

[0001] The invention relates to a color-changing engineered supercritical carbon dioxide fluid anhydrous dyeing and finishing system and a method thereof, belonging to the technical field of dyeing and finishing. Background technique

[0002] In recent years, supercritical fluid technology has been significantly improved and expanded from basic theoretical research to practical application, and has penetrated into many fields such as supercritical fluid dyeing, extraction, chemical reaction, and cleaning technology. As the main greenhouse gas, carbon dioxide is the most commonly used supercritical fluid. Its critical temperature and pressure are relatively mild, which are 31.1°C and 7.38MPa respectively.

[0003] However, the existing supercritical fluid dyeing equipment can only dye a single color effect in a single dyeing production, and it is still impossible to achieve multi-color production in one dyeing process, and only the color effect of textiles can...
