Embodiment 1

[0029] A device for dyeing with cylinders, such as figure 1 As shown, a main dye vat 100 and a slave dye vat 200 are included.

[0030] The upper part of the main dye vat 100 communicates with the upper part of the dye vat 200 through an air pressure balance pipeline 300 , and the air pressure balance pipeline 300 is provided with an air pressure balance valve 310 . The lower part of the main dyeing vat 100 communicates with the lower part of the secondary dyeing vat 200 through a liquid communication pipeline 400 , and a communication valve 410 is provided on the liquid communication pipeline 400 .

[0031] The main dye vat 100 is provided with a first water inlet pipe 110 and a first water outlet pipe 130, on which a first water inlet valve 111 and a first water outlet valve 131 are respectively arranged; the slave dye vat 200 is provided with a second water inlet pipe 210 and the second water outlet pipe 230, on which are respectively provided with the second water inlet v...

experiment example

[0047] 1. Dyeing effect.

[0048] Adopt the method for the dyeing of cylinders of embodiment 1, carry out the dyeing test of cylinders.

[0049] 1. Test plan:

[0050] The first dye solution main pump and the second dye solution main pump are both 50HZ dual-cylinder dyeing equipment. According to the method of the above-mentioned embodiment 1, when the dyeing is started, one main pump is turned on, the other main pump is turned off, and the two main pumps alternate switch, toggle every 15 seconds.

[0051] 2. Test situation:

[0052] Arrange for trial production of 1 cylinder of gray yarn, the color difference between inside and outside is comparable to that of normal bulk products, and the color dyeing is normal.

[0053] 3. Test data:

[0054] The test cylinder number is C304685780 / 2GYE0141, the package yarn specification is 0.9KG / piece, a total of 6 pieces, the computer value of the internal and external difference is tested, the computer test value and the human eye ev...

Abstract

The invention relates to a linked vat dyeing method, and belongs to the technical field of textile printing and dyeing. The linked vat dyeing method comprises the following steps that cheeses are placed into a main dye vat and a slave dye vat respectively, and an air pressure balance valve and a coupling valve are turned on; a dye solution is pumped into the main dye vat, a first dye solution main pump of the main dye vat is started, a second dye solution main pump of the slave dye vat is stopped, the dye solution is made to enter the slave dye vat through a first liquid flow pipeline, is leaked from the interior of a beam of the cheese of the slave dye vat to the exteriors of the cheese, enters a vat body of the slave dye vat and flows back to the main dye vat through the coupling valve, and dyeing is performed while the steps are executed repeatedly; after the preset time is up, the second dye solution main pump of the slave dye vat is started, the first dye solution main pump of the main dye vat is stopped, and circulated dyeing is performed according to the mode. According to the method, the first dye solution main pump and the second dye solution main pump are started alternately, and the cheese inside the slave dye vat and the cheese inside the main dye vat are dyed alternately. The dye solution utilization rate is increased, the dye bath ratio and energy consumption are lowered, and large production benefits are generated.

Description

technical field [0001] The invention relates to the technical field of textile printing and dyeing, in particular to a combined cylinder dyeing method. Background technique [0002] For the dyeing of a large number of single-color yarns of the same variety, the conventional dyeing method can reduce the number of vats used and avoid the phenomenon of vat difference (that is, the dyeing time in different dyeing vats, the dyeing liquid and the dyeing process and other factors. Different dyed fabrics have different color shades), and save dyeing water and auxiliaries. [0003] However, there are still some deficiencies in conventional multi-cylinder dyeing. For example, there is still a lot of room for saving dyeing water and auxiliaries in conventional multi-cylinder dyeing. In order to solve this problem, a method that can reduce the dyeing bath ratio of the combined tank, further save the amount of dyeing water and auxiliary materials, and at the same time reduce the cost o...
