Embodiment 1

[0031] Utilize supercritical CO2 The method for dyeing cloth of anhydrous dyeing system, comprises the following steps:

[0032] A. Preparation and storage of CO2: send the CO2 gas generated by the CO2 generation device into the storage tank by using the delivery plunger pump;

[0033] B. Cooling: The CO2 gas in the storage tank is cooled by the cooling device in turn. The pressure of the CO2 gas before and after cooling is 6MPA, and the temperature is 0°C;

[0034] C. Pressurization: Use a pressurized plunger pump to pressurize the CO2 gas, and the pressure of the CO2 gas after pressurization is 28MPA;

[0035] D. Heating: Use a heating device to form CO2 into a supercritical fluid, and heat the supercritical fluid to 120°C;

[0036] E. Dyeing: The circulation pump drives the mixture of supercritical fluid and dye to circulate in the circulation channel to dye the cloth in the autoclave; the pressure in the autoclave is 28MPA, the temperature is 120°C, and the circulation ti...
