Embodiment 1

[0029] Such as figure 1 As shown, the immersion dyeing equipment provided in Example 1 that can maintain a stable dye liquor concentration includes a dye vat 1, a dye liquor storage tank 2, an automatic feeding device 3, a dye liquor concentration data acquisition device 4, and a storage liquor concentration data acquisition device. device 5, metering pump 6 and terminal server 7;

[0030] The dye liquor concentration data acquisition device 4 is connected with the dye vat 1, and is used to collect the dye liquor concentration data in the dye vat 1, and the output end of the dye liquor concentration data acquisition device 4 is connected with the terminal server 7 signal; the terminal server 7 The output end of the metering pump 6 is connected to the metering pump 6, the inlet of the metering pump 6 is connected to the outlet of the dye solution storage tank 2 through a liquid outlet pipeline 8, and the outlet of the metering pump 6 is passed through a liquid inlet pipeline 9 ...

Embodiment 2

[0043] The difference between this embodiment 2 and embodiment 1 is that: the dipping dyeing equipment is not provided with a circulation pipeline connected with the dye solution outlet of the dye vat, and a storage solution concentration data acquisition device connected with the dye solution storage tank is not provided; The feeding device is directly connected with the dye liquor storage tank through a valve.

[0044] Utilize the dip dyeing equipment of embodiment 2 to carry out the method for dip dyeing, may further comprise the steps:

[0045] (1) Store the prepared dye solution in the dye solution storage tank, and the initial concentration of the dye solution in the dye solution storage tank is equal to the preset concentration, and inject a certain amount of dye solution into the dye tank by using a metering pump;

[0046] (2) The fabric is immersed in the dye vat for dyeing. During the dyeing process, the dye liquor concentration data acquisition device collects the r...

Abstract

The invention discloses dip dyeing equipment capable of maintaining stable dye liquor concentration. The dip dyeing equipment comprises a dye vat, a dye liquor storage tank, an automatic feeding device, a dye liquor concentration data acquisition device, a metering pump and a terminal server. The dye liquor concentration data acquisition device is connected with the dye vat and used for acquiringdye liquor concentration data in the dye vat, and the dye liquor concentration data acquisition device is in signal connection with the terminal server. The output end of the terminal server is connected with the metering pump, an inlet of the metering pump is connected with an outlet of the dye liquor storage tank, and an outlet of the metering pump is connected with the dye vat. The output end of the terminal server is connected with an automatic feeding device. The automatic feeding device is connected with the dye liquor storage tank. The invention further provides a dyeing method by usingthe dip dyeing equipment. The dye liquor concentration in the dye vat can be kept within the preset interval all the time, the dye-uptake rate is controlled within the optimal range, the problems ofcolor spots and the like caused by dye agglomeration due to high dye concentration are solved, dyeing uniformity is ensured, and the quality of dyed products is improved.

Description

technical field [0001] The invention belongs to the technical field of textile printing and dyeing, and in particular relates to a dipping dyeing device and a dyeing method capable of maintaining a stable dye liquor concentration. Background technique [0002] In the traditional process of intermittent dip dyeing of textiles, the dye solution prepared in advance in the dyeing material tank is often injected into the dyeing tank at one time at the beginning of dyeing. Change from fast to slow. At the beginning of dyeing, the dyes diffuse rapidly to the fabric, which easily leads to uneven dyeing, especially for dyes with poor solubility, which are easy to agglomerate at high concentrations, so that "dyeing defects" are prone to appear during the dyeing process. Therefore, it is difficult to achieve "one-time accurate" dyeing with the traditional intermittent dyeing process, especially for some sensitive color dyes, it often needs to be corrected through multiple color correc...
