Embodiment 1

[0028] A supercritical carbon dioxide fluid sampling device, the device includes a carbon dioxide storage tank 1, a three-way valve 2, a condenser 3, a carbon dioxide circulation tank 4, a high-pressure pump 5, a carbon dioxide heat exchanger 6, a dyeing kettle 7, and a separation kettle 8, The carbon dioxide storage tank 1 is connected to the inlet I of the three-way valve 2, and the outlet of the three-way valve 2 passes through the condenser 3, the carbon dioxide circulation tank 4, the high-pressure pump 5, the carbon dioxide heat exchanger 6, the dyeing kettle 7, the separation Kettle 8 is connected to inlet II of three-way valve 2;

[0029] Described dyeing still 7 comprises sample unit supporting frame 72, 12 detachable sample units 73, motor 74 that different quality dyes are housed, and described sample unit supporting frame 72 is arranged in the cylinder body of dyeing still 7, and described motor 74 seals pass through the dyeing kettle 7 and are connected to the sam...

Embodiment 2

[0031] A supercritical carbon dioxide fluid sampling device, the difference from Embodiment 1 is that the 12 sample units 73 are horizontally arranged on the sample unit support frame 72 .

Embodiment 3

[0033] A dyeing method utilizing the device described in embodiment 1, said method comprising the following steps:

[0034] ① Switch the three-way valve I2 to the inlet I, and the carbon dioxide in the carbon dioxide storage tank 1 is cooled to liquid carbon dioxide by the condenser 3 and stored in the carbon dioxide circulation tank 4;

[0035] ②During dyeing: the carbon dioxide in the carbon dioxide circulation tank 4 is transported to the carbon dioxide heat exchanger 6 through the high-pressure pump 5, and the carbon dioxide is heated to a supercritical state. The carbon dioxide fluid flows into the channel of each sample unit 73, and then passes into the sample unit 73. From the inlet and outlet of the detachable sealing cover I731, the carbon dioxide fluid passes through the gas-solid separation membrane 732 and the porous partition plate I733 to reach the dye chamber 734. The critical carbon dioxide fluid reaches the sample chamber 736 through the porous partition plate...

Abstract

The invention relates to a supercritical carbon dioxide fluid proofing device and a dyeing method and belongs to the technical field of spinning. The device comprises a dyeing kettle, the dyeing kettle comprises a sample unit supporting rack, multiple sample units and a motor, the sample unit supporting rack is arranged inside a cylinder body of the dyeing kettle, the motor passes through the dyeing kettle in a sealed mode and is connected with the sample unit supporting rack, the multiple sample units are arranged on the sample unit supporting rack, a channel used for allowing the carbon dioxide fluid to flow into the sample units is formed inside the sample unit supporting rack, and the sample units comprise a gas-solid separating membrane, a porous partition plate I, a dye chamber, a porous partition plate II, a sample chamber and a detachable sealing cover II in sequence from near to far at a carbon dioxide fluid inlet and outlet of a detachable sealing cover I. The supercritical carbon dioxide fluid proofing device and the dyeing method have the advantage of putting forward the supercritical carbon dioxide fluid proofing device for the first time.

Description

technical field [0001] The invention relates to a supercritical carbon dioxide fluid sampling device and a dyeing method, belonging to the technical field of textiles. Background technique [0002] Supercritical carbon dioxide fluid dyeing technology utilizes industrial carbon dioxide waste gas to dissolve dyes in a supercritical state, and carry the dyes to the surface of the fiber. After adsorption and fixation, the fabric can be dyed quickly and evenly; Vaporization is separated from the dye, eliminating the need for cleaning and drying processes; and the remaining dye and carbon dioxide can be recycled and reused, thereby reducing greenhouse gas emissions. Therefore, the use of supercritical carbon dioxide fluid instead of water medium overcomes the main shortcomings of water medium dyeing technology, and the fiber can be dyed without water during the dyeing process, which fully embodies the modern processing concept of cleaning, greening and environmental protection . ...
