Embodiment 1

[0042] Fluorescent yellow dyeing of aramid yarn

[0043]Smelt the bobbins first: use a degreasing agent with a concentration of 3g / L and a phosphite triester with a concentration of 2g / L at a temperature of 90°C with a liquor ratio of 1:10 to process the yarn in the meridian winding process. Aramid yarn or aramid sewing thread boil for 10 minutes.

[0044] Dissolve the fluorescent yellow dye in the dyeing vat, and ensure that the concentration of the dye in the dyeing vat is: cationic Y10GFF0.42-0.48g / L, acetic acid 3-3.5g / L and sodium chloride 20g / L, then heat the dye to 70°C, then add carrier HPS505 into the dye vat, the concentration of HPS505 is 40g / L, run for 5-10 minutes, heat the mixture in the dye vat to boiling within 60 minutes for boiling dyeing.

[0045] After the boiling dyeing is completed, the pH value of the mixture in the dyeing vat is adjusted to 9, the dyeing is incubated at 130°C for 30 minutes, and then the color is fixed for 30 minutes. After the color ...

[0063] Dyeing navy blue A color on aramid yarn

[0064] Smelt the bobbins first: use a degreasing agent with a concentration of 3g / L and a phosphite triester with a concentration of 2g / L at a temperature of 90°C with a liquor ratio of 1:10 to process the yarn in the meridian winding process. Aramid yarn or aramid sewing thread boil for 10 minutes.

[0065] Dissolve the dye for dyeing navy blue A color in the dyeing vat, and ensure that the concentration of the dye in the dyeing vat is: Y X-GL1.8g / L, R X-GRL0.78g / L, B X-BL2.1g / L, acetic acid 3 -3.5g / L and sodium chloride 20g / L, then heat the dye to 60°C, then add the carrier HPS303 into the dye vat, the concentration of HPS303 is 40g / L, run for 5-10 minutes, put the mixture in the dye vat Heat up to boiling within 60 minutes and carry out boiling dyeing for 60 minutes.

[0066] After the boiling dyeing is completed, the pH value of the mixture in the dyeing vat is adjusted to 9, the dyeing is incubated at 130°C for 30 minutes...

Abstract

The invention discloses a cheese dyeing method for aramid yarns or aramid sewing threads. The cheese dyeing method comprises the following steps of: boiling off the aramid yarns or the aramid sewing threads subjected to cheese winding for 10 minutes by using a degreasing agent with the concentration being 3g / L and triester phosphite with the concentration being 2g / L at 90 DEG C according to a bath rate of 1:10; dissolving dyes in a dye vat and heating to 60-80 DEG C, then adding corresponding vectors into the dye vat, putting the aramid yarns or the aramid sewing threads into the dye vat after running for 5-10 minutes, then carrying out boiling dyeing for 60 minutes, raising the temperature in the dye vat to 130 DEG C after the boiling dyeing, preserving the heat and dyeing for 30 minutes, and carrying out color fixing for 30 minutes; and washing, dehydrating and drying the aramid yarns or the aramid sewing threads subjected to color fixing to obtain dyed aramid yarns or aramid sewing threads. According to the cheese dyeing method, the worldwide problem that fluorescent fiber cannot be produced by dope dyeing aramid is solved.

Description

technical field [0001] The invention relates to the field of flame-retardant fabrics and protective clothing, in particular to a method for dyeing a package of aramid yarn or aramid sewing thread. Background technique [0002] Aramid fibers are divided into two types: stock solution dyeing and post-white dyeing. The former is more expensive; it is usually used in emergency clothing for firefighters, anti-riot police clothing and special forces clothing. It is used in high-risk industries such as petroleum, petrochemical and other fields. high and discarded. In addition, the color is also limited; for example, the dope dyed aramid fiber cannot produce fluorescent colored fibers. In the prior art, various dyeing methods have been used to treat aramid fiber, but the color fastness is poor and the cost is high, which limits the application space of aramid fiber. [0003] Therefore, prior art still needs further improvement and development. Contents of the invention [0004]...
