Embodiment Construction

[0015] Technical scheme of the present invention comprises supercritical CO 2 Fluid dyeing process and supercritical CO 2 Fluid dyeing device.

[0016] 1. Supercritical CO 2 Fluid Dyeing Process

[0017] The core technology of the present invention is to use CO in a supercritical state 2 As a dye carrier for dyeing fabrics. liquid CO 2 Inject CO 2 in memory. The fabric is put into the dyeing kettle, and the solid dye is put into the dye kettle. Then start the booster pump to pump the liquid CO 2 from CO 2 Memory is injected into the dyeing system. CO of test dyeing unit 2 The design volume of the storage is 100 liters, liquid CO 2 Consumption is 150 kilograms. The staining requirement is deep staining. For 100 kilograms of dyed fabrics, the amount of solid dye is 7.5 kilograms. Then heat and pressurize the dyeing system to the dyeing temperature and pressure. The test temperature is 110°C and the pressure is 24Mpa. Then start the circulating pump to make the s...

Abstract

The present invention relates to a fluid waterless dyeing technique, in the concrete, it relates to a dyeing technique using carbon dioxide as dye carrier under the supercritical condition. The invented dyeing technique includes dyeing process and dyeing equipment. Its dyeing process includes the following steps: heating and pressurizing liquid CO2 in dyeing system and making said liquid CO2 into supercritical fluid; utilizing circulation pump to make CO2 be continuously and circularly reciprocated between dyeing tank and dye tank, dissolving dye while dyeing textile, then using new CO2 to wash dyed textile, after the dyed textile is washed, said equipment releases pressure, recovering CO2 and dye. Said dyeing equipment includes dyeing system and recovery separation system, said two systems one connected by means of pipeline.

Description

technical field [0001] The invention discloses a textile fluid anhydrous dyeing technology, specifically a dyeing technology in which carbon dioxide in a supercritical state replaces water as a dye carrier. Background technique [0002] For the dyeing of textiles, from the original handicraft operation to the modern large-scale industry, it is always to adopt the method of dyeing with water as the dyestuff carrier. According to relevant materials, my country's textile industry alone uses more than 1 billion cubic meters of water every year. And the printing and dyeing industry with water as the carrier of dyestuffs discharges a large amount of waste water containing inorganic salts and alkalis every year. Printing and dyeing consumes a lot of water, and the discharged wastewater has seriously polluted our scarce water resources. In today's deteriorating ecological environment, saving water and reducing environmental pollution has become a top priority. Also do not have th...
