Problems solved by technology

[0003] In existing research projects, such as the Hong Kong short-term patent application number 06112486.0, although supercritical carbon dioxide dyeing has been proven to be widely used in the dyeing of synthetic fibers, it lacks the treatment of textile materials before and after dyeing. The specific process of the treatment, but the pre-treatment and post-treatment of the dye is also a very important step in the actual dyeing production

Embodiment 1

[0038] This embodiment provides a method for dyeing and finishing textile materials with supercritical fluid. Before dyeing textile materials with supercritical fluid, use supercritical fluid to clean the pretreatment process of textile materials. The specific process is as follows:

[0039] The carbon dioxide fluid is stored in the storage tank at room temperature and the pressure is about 5Mpa. The carbon dioxide enters the cooler and the temperature is controlled between 0 and 10°C (preferably 5°C), so that the carbon dioxide can fully form a liquid and the pressure is kept at About 5Mpa, the carbon dioxide is raised to a suitable pressure through a high-pressure pump, and the pressure can be controlled to about 10Mpa to reach a supercritical state, and then the temperature is raised to 50-100°C through a heat exchanger. Into the autoclave, the textile material is rinsed. The carbon dioxide containing oil is reduced to about 5Mpa by decompression. At this time, the absorbed...

Embodiment 2

[0040] Embodiment 2: Example of dyeing and functional material addition:

[0041] This embodiment provides a textile material dyeing and finishing method with supercritical fluid. Before dyeing the textile material with supercritical fluid, the pretreatment process of cleaning the textile material with supercritical fluid is used, and the cleaning pretreatment process and implementation Example 1 is exactly the same and will not be repeated here. The process of dyeing and adding functional materials is as follows:

[0042] The carbon dioxide fluid is stored in the storage tank at room temperature and the pressure is about 5Mpa. The carbon dioxide enters the cooler and the temperature is controlled between 0 and 10°C (preferably 5°C), so that the carbon dioxide can fully form a liquid and the pressure is kept at About 5Mpa raises the carbon dioxide to a suitable pressure through a high-pressure pump to make it reach a supercritical fluid state.

[0043] The pressure can be con...

Embodiment 3

[0044] Embodiment 3: This embodiment provides a kind of textile material dyeing and finishing method of supercritical fluid, comprises the post-treatment process of removing floating color after dyeing is finished, specifically as follows:

[0045] The carbon dioxide fluid is stored in the storage tank at room temperature and the pressure is about 5Mpa. The carbon dioxide enters the cooler and the temperature is controlled between 0 and 10°C (preferably 5°C), so that the carbon dioxide is fully liquid and the pressure is kept at about The carbon dioxide is raised to a suitable pressure through a high-pressure pump at 5Mpa, and the pressure can be controlled to about 10Mpa to reach a supercritical fluid state, and then the temperature is raised to 50-100°C through a heat exchanger. Into the autoclave, the textile material is rinsed. The carbon dioxide containing the floating color dye is reduced to about 5Mpa through the pressure reducing valve. At this time, the absorbed heat ...

Abstract

The present application is directed to a method of waterless processing of textile materials using supercritical fluid, including the use of supercritical fluid to dye the textile materials, the use of supercritical fluid for a pre-processing procedure of cleansing the textile materials, and the use of supercritical fluid to wash off unfixed dyes and cleansing of the textile materials and to perform the post-processing procedure of adding functional materials after the use of supercritical fluid to dye the textile materials. The present application provides an integrated technology of pre-processing, dyeing and post-processing of textile materials using supercritical fluid. At the same time, cleansing and dyeing are performed which effectively raises the efficiency.

Description

technical field [0001] The invention relates to a supercritical fluid anhydrous finishing method for textile materials. Background technique [0002] The traditional textile finishing and dyeing process mainly uses water as the medium. In addition to consuming a large amount of water resources, there are also problems such as large environmental pollution, high energy consumption, and high processing costs. At present, many countries and regions have tightened environmental protection regulations, making the traditional dyeing and finishing industry face difficulties. In order to solve the problem of water pollution caused by the textile dyeing and finishing industry, the Hong Kong Productivity Council began to develop the supercritical carbon dioxide water-free dyeing process in 2005, which can use recycled industrial carbon dioxide as a carrier to carry dyes to dye textiles in a supercritical state . The feature of this technology is that the dyeing process does not use ...
