Embodiment 1

[0026] A color-changing engineered supercritical carbon dioxide fluid anhydrous dyeing and finishing system, the system includes a carbon dioxide gas source 1, and the carbon dioxide gas source 1 is connected to the inlet I of the carbon dioxide circulation tank 4 through a heater 2 and a condenser 3 in sequence , the outlet of the carbon dioxide circulation tank 4 is connected to each group of magnetic circulation pumps 9 through the precooler 5, the high pressure pump 6, and the preheater 7 successively, and the magnetic circulation pump 9 is connected to the inlet I of the dyeing and finishing kettle 8 respectively. connected, the outlet I of the dyeing and finishing kettle 8 returns to its inlet I through the respective magnetic circulation pump 9, the outlet II of the dyeing and finishing kettle 8 is connected with the separation kettle 11 through the respective adsorption kettle 10, and the outlet of the separation kettle 11 is The particle online detector 12 is connected...

Embodiment 2

[0029] A dyeing and finishing method utilizing the system described in Example 1, said method is: place Disperse Blue 60, Disperse Red 153, and Disperse Yellow 114 in different dyeing chambers respectively, and the consumption is 0.5w / w%. Super-imitation cotton fiber, polyester fabric, and wool cheese are respectively placed on different textile dyeing and finishing racks 86;

[0030] The carbon dioxide is heated and then cooled to a liquid state and stored in the carbon dioxide circulation tank 4. During dyeing and finishing, the carbon dioxide in the carbon dioxide circulation tank 4 is condensed, boosted, and heated to a supercritical state, and the supercritical carbon dioxide fluid enters the dyeing and finishing tank 8 of each group Finally, dissolve the dye first, then dye the textiles, circulate the dyeing under the action of the magnetic circulation pump 9, and dye for 60 minutes under the conditions of 120°C and 24MPa. Initial separation, the adsorption temperature i...

Embodiment 3

[0033] A kind of dyeing and finishing method utilizing the system described in embodiment 1, the difference with embodiment 2 is:

[0034] Disperse Red 153 was placed in different dye chambers, and the dosage was 1w / w%;

[0035] Dyeing at 100°C and 24MPa for 60min.

[0036] After testing, the K / S values ​​of dyed super-imitation cotton fiber, polyester fabric, and wool cheese are 11.4, 10.6, and 5.2 respectively, and the standard deviation of the dyed K / S value is lower than 0.25%. , The color fastness to rubbing is above grade 4, and the color fastness to sunlight is above grade 6, meeting the requirements of commercial production.

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...
