Embodiment 1

[0018] A kind of yarn dyeing process, complete the yarn dyeing process through the loose winding step, warping step, dyeing step and post-processing step, the specific steps are as follows:

[0019] (1) Loose winding steps: loose bobbin yarn density range is 0.27g / cm 3 ;

[0020] (2) Warping steps: the warp beam density range is 0.36g / cm 3 ;

[0021] (3) Dyeing step: The dyeing process adopts a one-bath method, using an auxiliary agent to infiltrate the yarn first, and then coloring. The auxiliary agent is composed of alkyl metaphosphate and polyethylene glycol ester, and the mass percentage of the two is is 20:80;

[0022] (4) Post-processing step: In the post-processing process, the bobbins are not oiled.

[0023] Dyeing steps, the specific steps are:

[0024] 1) First use the auxiliary agent for infiltration: the auxiliary agent and water are mixed at a mass ratio of 1:500 to form a permeate, and the yarn is immersed in the permeate at a temperature of 45°C for 30 minu...

Embodiment 2

[0028] A kind of yarn dyeing process, complete the yarn dyeing process through the loose winding step, warping step, dyeing step and post-processing step, the specific steps are as follows:

[0030] (2) Warping steps: the warp beam density range is 0.44g / cm 3 ;

[0031] (3) Dyeing step: The dyeing process adopts a one-bath method, using an auxiliary agent to infiltrate the yarn first, and then coloring. The auxiliary agent is composed of alkyl metaphosphate and polyethylene glycol ester, and the mass percentage of the two is is 35:65;

[0032] (4) Post-processing step: In the post-processing process, the bobbins are not oiled.

[0033] Dyeing steps, the specific steps are:

[0034] 1) First use the auxiliary agent for infiltration: the auxiliary agent and water are mixed at a mass ratio of 2:500 to form a permeate, and the yarn is immersed in the permeate at a temperature of 60°C for 40 minu...

Embodiment 3

[0038] A kind of yarn dyeing process, complete the yarn dyeing process through the loose winding step, warping step, dyeing step and post-processing step, the specific steps are as follows:

[0039] (1) Loose winding steps: loose bobbin yarn density range is 0.3g / cm 3 ;

[0040] (2) Warping steps: the warp beam density range is 0.4g / cm 3 ;

[0041] (3) Dyeing step: The dyeing process adopts a one-bath method, using an auxiliary agent to infiltrate the yarn first, and then coloring. The auxiliary agent is composed of alkyl metaphosphate and polyethylene glycol ester, and the mass percentage of the two is is 26:74;

[0042] (4) Post-processing step: In the post-processing process, the bobbins are not oiled.

[0043] Dyeing steps, the specific steps are:

[0044] 1) First use the auxiliary agent for infiltration: the auxiliary agent and water are mixed at a mass ratio of 1.5:500 to form a permeate, and the yarn is immersed in the permeate at a temperature of 55°C for 35 minu...

Abstract

The invention discloses a yarn dyeing process, which is characterized in that: the yarn dyeing process is completed through a loose winding step, a warping step, a dyeing step and a post-treatment step; the advantage of the invention is that the invention saves the The oiling process is omitted in the pre-treatment process and the post-treatment process. The permeate will not be discharged after the auxiliary agent has penetrated, and the next step of coloring will be carried out directly. There is no need to add retarder or leveling agent during coloring, which helps The dye can help the dye to be directly dyed on the yarn and achieve the purpose of level dyeing; the invention greatly shortens the dyeing process time and reduces the discharge of sewage; saves the auxiliary agent used in the pretreatment process and makes the yarn The pH value of the fabric is lowered, making it more soft and durable.

Description

technical field [0001] The invention relates to the technical field of textiles, in particular to a yarn dyeing process. Background technique [0002] Cotton fabric has been popular among people since ancient times. It is soft, warm, durable, and has good moisture absorption and perspiration effects. It has also been recognized as an excellent textile in terms of cotton planting and dyeing techniques. Cotton fiber is easy to dye, which is mainly reflected in the performance of the fiber itself, which can make the dye achieve a good dyeing rate and have excellent color fastness, which is also impossible for other fabrics. However, although the impurities in the cotton fiber only account for 6% of the total amount, they still have a great impact on the dyeing effect in the dyeing process. It affects the inner quality of the bobbin and causes waste of raw materials. Contents of the invention [0003] The object of the present invention is to provide a yarn dyeing process th...
