Problems solved by technology

The whole dyeing process needs to consume a lot of water
Although some new dyeing machines with low dyeing liquor ratio have been developed, the three dyeing steps including yarn pre-treatment, dyeing and post-treatment require that the yarn must be completely immersed in the dye solution, otherwise it will affect the quality of dyeing. , such as level dyeing, etc. have a major impact

Embodiment 1

[0028] Embodiment one: 80S / 2 pure cotton cheese dyeing (850 kilograms)

[0029] The water-saving dyeing method of 80S / 2 pure cotton cheese in the present embodiment is as follows:

[0030] 1. Determination of water level:

[0031] According to the adjustment, it is determined that the optimum water level for 850 kilograms of pure cotton cheese is 3200 liters.

[0032] 2. Dyeing process

[0033] Scouring→acid washing→washing at 85 degrees→compressed air squeezing→cold water washing→dyeing→high temperature washing→compressed air squeezing→pickling→soaping→compressed air squeezing→hot water washing→compressed air squeezing→cold washing →Compressed air to squeeze water→Fix color→Drying;

[0034] 1) The running direction of the main pump of the dye vat is a one-way cycle from inside to outside;

[0035] 2) The main pump speed range is 1200 rpm;

[0036] 3) The washing time is 5-10 minutes;

[0037] 4) Squeeze water by compressed air 1-3kg / cm2;

Embodiment 2

[0038] Embodiment two: 100S / 2 pure cotton beam dyeing (300 kilograms)

[0039] 1. Determination of water level:

[0040] According to adjustment, the optimal water level of determining 300 kilograms of pure cotton beam yarns is 2900 liters.

[0041] 2. Dyeing process

[0042] Scouring→acid washing→water washing at 85℃→compressed air squeezing→cold water washing→dyeing→high temperature washing→compressed air squeezing→pickling→soaping→compressed air squeezing→hot water washing→compressed air squeezing→cold washing →Compressed air to squeeze water→Fix color→Drying;

[0043] 1) The running direction of the main pump of the dye vat is a one-way cycle from inside to outside;

[0044] 2) The main pump speed range is 1150 rpm;

[0045] 3) The washing time is 5-10 minutes;

[0046] 4) Squeeze water by compressed air at 1-3kg / cm2.

Abstract

The invention relates to a water conservation technique for yarn dyeing, wherein low level dyeing is realized through modification of dye liquor recycling pattern and optimization of the dyeing process, the water consumption can be 20-50% lower then the conventional procedures.

Description

technical field [0001] The invention relates to water-saving technology, in particular to a novel yarn dyeing water-saving technology. By adopting water-saving dyeing technology, the amount of dyeing auxiliaries and energy can be saved at the same time, and the dyeing time can be shortened. The method of the invention is suitable for yarn dyeing, not only for the dyeing of chemical fiber yarns, but also for the dyeing of blended yarns or cotton yarns. The dyed form of yarn can be warp beam or cheese. Background technique [0002] The textile printing and dyeing industry has always been a major consumer of water resources. Along with the consumption of water resources, a large amount of wastewater is produced. The treatment cost of this wastewater is very high. If it is discharged directly without treatment, it will have a negative impact on the ecological environment, especially rivers and rivers. Groundwater resources have been seriously polluted. [0003] With the devel...
