Embodiment 1

[0020] See attached figure 1 , which is a structural schematic diagram of a color-fixing processing device for textiles provided in this embodiment. It includes a color-fixing liquid storage tank, a color-fixing tank and a supercritical carbon dioxide fluid treatment system with a circulation pump. The belt circulation system is omitted in the figure. Pumps for supercritical carbon dioxide fluid handling systems.

[0021] The color-fixing liquid storage kettle 2 is a cylindrical cavity with an inverted "mountain" type tubular fluid distributor 4 inside, which is composed of three interconnected pipes, with the mouth of the pipe bent downward, and two of the pipes are circulating fluid The outlet pipe, the pipeline located in the center is the circulating fluid inlet pipe 1, which communicates with the supercritical carbon dioxide fluid system through the opening at the lower end of the color-fixing liquid storage tank, and the color-fixing liquid storage tank and the color-fi...

Abstract

The invention discloses a method for fixing the colors of textiles and a device thereof, and particularly discloses a technology for performing phase transfer catalytic color fixing on natural fiber textiles by adopting dispersed active dyes in a supercritical carbon dioxide fluid. The lower end of a color fixing kettle is connected with a color fixing liquid storing kettle; a fluid distributor is arranged in the color fixing liquid storing kettle; a circulation fluid is fully contacted with color fixing mixed liquid containing a color fixing alkaline accelerant and a phase transfer catalyst when flowing through the fluid distributor; the color fixing alkaline accelerant is transferred onto fibers by using a phase transfer catalyst principle, so that the reaction activity between functional groups on the fibers and dyes is increased, and color fixing of dyes on the fibers is realized. According to the method, a phase transfer catalytic color fixing method and a device thereof with a reasonable structure is adopted, so that the color fixing efficiency of dyes on textiles is increased remarkably; moreover, equipment and a process are simple, and operation is convenient.

Description

technical field [0001] The invention relates to a unit device and method for color-fixing processing of fiber textiles, in particular to a method for performing phase-transfer catalytic color-fixing processing of fiber textiles, especially natural fiber textiles, by using disperse reactive dyes in a supercritical carbon dioxide fluid The device and method belong to the technical field of textile dyeing and finishing. Background technique [0002] Supercritical carbon dioxide fluid dyeing processing technology has remarkable ecological, environmental protection, energy saving and emission reduction and other clean production characteristics, and is of great significance to changing the current situation of high pollution and high energy consumption in the traditional textile printing and dyeing industry. At present, polyester and other hydrophobic synthetic fiber textiles use disperse dyes, which can obtain good dyeing effects in supercritical carbon dioxide fluid processing....
