Problems solved by technology
However, there is a serious problem in the ozone process. If the ozone concentration is too high or the treatment time is a little longer, the surface of the fabric will turn yellow irreversibly. The concentration of ozone gas and the treatment time are extremely difficult to control

Embodiment example
[0039] The original traditional fading treatment line is transformed, and a recovery tank 8 is added, and an aeration device 81 is arranged at the bottom of the recovery tank 8 . The original traditional fading treatment line includes nine tanks. A singeing machine 1 is added before the nine tanks, and a reduction pool 6 is added after the nine tanks, so that the denim fabrics are successively passed through the singeing machine, the nine tanks, and the reduction tank. Pool 6 and the original anti-yellowing pool 7, set the speed of singeing machine 1 to 70 m / min.
[0040] Among the nine tanks of the continuous dyeing machine, the original cloth guide roller 34 in the tank, the second to the seventh tanks are sealed according to the following structure to form the oxidation tank 3: the bottom of the oxidation tank 3 A gas supply device 35 is provided, and the gas supply device 35 communicates with the ozone generator through a valve. The inlet and outlet of the oxidation tank t...

The invention discloses a jean fabric environment-friendly fading treatment process and an after-finishing thread, and belongs to the field of dyeing and finishing, the process comprises a singeing procedure, a desizing procedure and a fading procedure, the operation of the fading procedure comprises the steps that a jean fabric continuously passes through a plurality of oxidation tanks, the oxidation tanks are filled with water and ozone and a resist agent dissolved in the water, and the oxidation tanks are filled with a dyeing agent; according to the passing sequence of the denim fabric, the ozone concentration of the solution in the next oxidation box groove is 10%-20% lower than that in the previous oxidation box groove, and the concentration of the resist agent in all the oxidation box grooves is 0.5 g / L-2g / L. When the ozone solution is used for treatment, on one hand, the ozone concentration is easier to control, and on the other hand, the concentration of the resist agent in the oxidation box grooves is more uniform. On one hand, the ozone concentration in the solution in the oxidation tank is set to be gradually reduced according to the passing sequence of the denim fabric, so that too high ozone concentration and too long treatment time are avoided, on the other hand, a resist agent can be added in a liquid environment, staining and yellowing of the denim fabric are avoided, and the process is simple in wastewater component and low in wastewater treatment cost.
Description
technical field [0001] The invention relates to an environment-friendly fading treatment process and a finishing line for denim fabrics, belonging to the field of dyeing and finishing. Background technique [0002] The washing process is a part of the denim clothing finishing process, and it is a key process that determines the added value of denim clothing. The purpose is to make old denim clothing. Indigo dyes commonly used in denim yarn dyeing are vat dyes. The traditional washing process includes enzyme bleaching, oxygen bleaching, chlorine bleaching, manganese bleaching, etc., so that the indigo dye on the fabric is oxidized and faded. long. On the other hand, these water washing processes need to use a large amount of hydrogen peroxide, sodium hypochlorite, sodium hydroxide, and potassium permanganate, so that the wastewater contains a large amount of chloride ions and manganese ions, and the wastewater treatment cost is high. [0003] With the progress of the socie...
