Problems solved by technology

The known dyeing process of disperse dyes needs to be cleaned. The cloth sample needs to be washed many times to achieve the required process. Therefore, a large amount of printing and dyeing wastewater that is difficult to treat will be generated in this process.
At the same time, the dyeing wastewater of disperse dyes has a relatively large component in the wastewater composition of the entire printing and dyeing factory, and it is also relatively difficult to treat, and it is also relatively harmful to the environment.
Although the existing wastewater treatment technology already has a good wastewater treatment effect, its technical requirements are high, the investment is large, and the treatment cost is relatively high.

Embodiment 1

[0031] AF-R orange (azo type)

[0032] Test cloth: polyester T100D / 144F semi-dull

[0033] Disperse dye: AF-R orange Liquor ratio: 1:20

[0034] Test equipment: Rapid ECO-24

[0035] Test process: high temperature, high pressure and less water dyeing process:

[0036] Weighing (disperse dye 2% owf, high temperature leveling agent SY-WS 1% owf) → chemical material → dyeing (pH value 5, heat up to 130°C at 1.8°C / min and keep it for 40min, then cool down to 80°C) → Add reduction cleaning agent (3% owf) → reduction cleaning (pH value 5, heat up to 90°C at 1.8°C / min and keep it warm for 25min, then cool down to 80°C) → iron dry

[0037] In the water-less dyeing process, the residual liquid after reduction and cleaning is recycled again and used as water for the next dyeing, and the cycle is ten times.

[0038] The relevant performance test results are shown in Table 1.

Embodiment 2

[0046] FB red (anthraquinone type)

[0047] Test cloth: polyester T100D / 144F semi-dull

[0048] Disperse dye: FB red bath ratio: 1:50

[0049] Test equipment: Rapid ECO-24

[0050] Test process: less water dyeing process:

[0051] Weighing (disperse dye 2% owf, high temperature leveling agent SY-WS 1% owf) → chemical material → dyeing (pH value 5, heat up to 130°C at 1.8°C / min and keep it for 40min, then cool down to 80°C) → Add reduction cleaning agent (3% owf) → reduction cleaning (pH value 5, heat up to 90°C at 1.8°C / min and keep it warm for 25min, then cool down to 80°C) → iron dry

[0052] In the water-less dyeing process, the residual liquid after reduction and cleaning is recycled again and used as water for the next dyeing, and the cycle is ten times.

[0053] The relevant performance test results are shown in Table 2.

Embodiment 3

[0062] color matching navy blue

[0063] Test cloth: polyester T100D / 144F semi-dull

[0064] dye:

[0065] C-BN Black 0.6%

[0066] S-5BL Ruby 0.2%

[0067] ES-BR Deep Blue 1.2%

[0068] Bath ratio 1:20

[0069] Test equipment: Rapid ECO-24

[0070] Test process: less water dyeing process:

[0071] Weighing (disperse dye 2% owf, high temperature leveling agent SY-WS 1% owf) → chemical material → dyeing (pH value 5, heat up to 130°C at 1.8°C / min and keep it for 40min, then cool down to 80°C) → Add reduction cleaning agent (3% owf) → reduction cleaning (pH value 5, heat up to 90°C at 1.8°C / min and keep it warm for 25min, then cool down to 80°C) → iron dry

[0072] In the water-less dyeing process, the residual liquid after reduction and cleaning is recycled again and used as water for the next dyeing, and the cycle is eight times.

[0073] The relevant performance test results are shown in Table 3.

Abstract

The invention relates to the technical field of dyeing, in particular to a high-temperature high-pressure less-water dyeing process. After dyeing in disperse dye liquor, a product is added into a terylene cleaning agent for reduction cleaning, and a cloth sample is directly dried; the terylene cleaning agent is TF-288B, and the use amount is 3% owf, so that the product can reach a normal dyeing process without water washing, and waste water obtained after dyeing can be recycled and can be used as dyeing water again without treatment. According to the high-temperature high-pressure less-water dyeing process, the dyeing and finishing process can be optimized from a source, the water consumption is saved, the wastewater treatment cost is reduced, and the process is a novel environment-friendly dyeing technology.

Description

technical field [0001] The invention relates to the technical field of dyeing, in particular to a high-temperature, high-pressure and less-water dyeing process. Background technique [0002] The current situation of my country's water resources is characterized by a large total amount and small individuals. Although the total amount of fresh water resources ranks fourth in the world, the per capita water resources are only 1 / 4 of the world's average level, and it is the 13 countries with the poorest per capita water resources in the world. one of the countries. The water environment capacity of various rivers and lakes has long been unable to bear water pollution, but various sewage discharges are constantly increasing. As far as the current situation of water pollution in rivers is concerned, industrial wastewater is the main source of pollution. The printing and dyeing industry is a typical high water consumption industry. The waste water produced by it is consumed in a h...
