Embodiment
[0021] Example: such as figure 1 As shown, an overall circulation system of indigo dyeing solution, including a reducing solution tank 1 for holding a mixture of sodium hydrosulfide and caustic soda, an indigo stock solution tank 2 for holding an indigo powder solution, and a plurality of indigo dyeing tanks for pad dyeing Dyeing tank 3, circulating material tank 4, recycling material tank 5 and controller. The discharge port 41 of the circulating feed tank 4 is connected to the liquid replenishment port 31 of each indigo dyeing tank 3 through the first water pump 42 and the discharge pipe 43, and the liquid discharge port 32 of each indigo dyeing tank 3 passes through the return pipe 44 And the second water pump 45 is connected to the material return port 46 of the circulation tank 4 to form a circulating dye liquor circulation system. The feeding end of described reclaiming trough 5 is connected to return pipe 44 through pipeline, and electromagnetic valve 6 and the 3rd wat...

The invention provides an integral circulation system for an indigo dye liquor. The integral circulation system comprises a reduction liquor cylinder, an indigo stock solution cylinder, a plurality ofindigo dye tanks, a circulation trough, a recovery trough and a controller; the whole indigo dye liquor is circulated as a whole through the circulation trough, and the feeding end of the recovery trough is connected to a return pipe through a pipeline; the discharging end of the recovery trough is connected to the indigo stock solution cylinder, and the reduction liquor cylinder and the indigo stock solution cylinder are connected to the circulation trough through electromagnetic valves and pumps; and a sampling port is connected to the circulation trough and is connected to a pH meter, an oxidation-reduction potential tester and a spectrophotometer through pipelines. The circulation trough is used as a process detection point and a process control point, dye liquor parameters detected by the PH meter, the oxidation-reduction potential tester and the spectrophotometer are received through the controller, the indigo powder content and the sodium hydrosulfite content of dye liquor in the circulation trough are automatically controlled, and finally it is guaranteed that the dye liquor in all the indigo dye troughs is stable and meets the process requirements.
Description
technical field [0001] The invention belongs to the technical field of fabric dyeing, and in particular relates to an indigo dye liquor overall circulation system. Background technique [0002] Batik is an ancient traditional folk textile printing and dyeing handicraft of ethnic minorities in my country. Batik is to use a wax knife to dip melted wax to draw flowers on the cloth and then dip them in indigo. After dyeing and removing the wax, the cloth will show white flowers on a blue background or blue flowers on a white background. A variety of patterns, simple and elegant tones, and unique styles, used to make clothing and various daily necessities look fresh and pleasing to the eye, full of ethnic characteristics. With the development of technology, batik can be mass-produced through mechanization. [0003] Indigo dye is a kind of vat dye, which is insoluble in water. Before dyeing, indigo dye must be treated with reducing agent and other auxiliaries, so that indigo dye c...
