Problems solved by technology

[0003] At present, most wool nitrile dyeing processes generally carry out soaping treatment and multiple cleaning treatments during the post-treatment process of wool nitrile skein yarn. At present, because the cleanliness of the dyeing water after dyeing is difficult to control, the dyeing water will be discharged and re- Add clean water, then pour in an appropriate amount of soaping agent, and then soap the wool nitrile after stirring. After the soaping is completed, the soaping liquid is discharged, and the next step is to add cleaning water for rinsing. The product obtained after processing requires a lot of consumption water, wasting water

Embodiment 1

[0025] Embodiment 1, a kind of dyeing process of wool nitrile mainly comprises the following steps:

[0026] Step S1, hang the yarn into the vat, hook the wool nitrile skein to the steam pipe in the dyeing vat (the dyeing vat is produced by the Boiler Operation Department of Dalang Zhongshun, Dongguan City) at certain intervals;

[0027] Step S2: In the first stage, the skein is soaked into the material, and water is passed into the dye vat, and the dispersant is added and then stirred. The heating system of the dye vat heats the water and raises the temperature to 40°C, and then adds neutral dye (neutral orange RL) ;

[0028] Step S3, the first stage of temperature-rising dyeing, for the wool nitrile skein that needs to be dyed to a light color, the temperature-rising speed is 1°C / min to carry out temperature-rising dyeing, and dyeing to 70°C, and then add cationic dyes (using cationic yellow X-6G as As a cationic dye), heat up to 100°C at a heating rate of 1min / °C and keep ...

Embodiment 2

[0032] Example 2, a wool nitrile dyeing process, differs from Example 1 in that in step S3, after dyeing to 75°C, the temperature continues to rise to 80°C, and then the temperature is raised to 90°C within 1.5min / °C. °C, and then heated to 100 °C within 1 min / °C.

Embodiment 3

[0033] Example 3, a wool nitrile dyeing process, the difference from Example 1 is that in the step S3, after dyeing to 75°C, continue to heat up to 80°C, and then heat up to 90°C within 2min / °C , and then heated up to 100°C within 1min / °C.

Abstract

The invention discloses a dyeing process of wool acrylic and relates to the field of skein dyeing. The dyeing process mainly comprises the following steps: S1, enabling wound yarns to enter a vat; S2,carrying out first-stage wetting and feeding on the skein; S3, carrying out first-stage temperature rise and dyeing; S4, carrying out first-stage water outlet cooling; S5, carrying out second-stage wetting and feeding on the skein; S6, carrying out second-stage temperature rise and dyeing; S7, adding alkali for fixing color; S8, carrying out second-stage water outlet cooling; S9, flushing and carrying out alkali washing; S10, neutralizing and carrying out finishing treatment; S11, draining water, cooling and discharging from the vat. According to the dyeing process disclosed by the invention,by controlling dyeing conditions, dyeing water can be used as a dosing solution of a soaping agent and can be directly used without being drained, thereby improving the utilization rate of water resources.

Description

technical field [0001] The invention relates to the field of hank yarn dyeing, in particular to a wool nitrile dyeing process. Background technique [0002] Wool acrylic is a blend of two fibers of different materials. The two materials are acrylic and wool. The dyes required for dyeing each fiber are different. For example, acid dyes are needed for dyeing wool, and cationic dyes are needed for dyeing acrylic fibers. Not only that, but also different dyeing conditions such as temperature and time are used in the dyeing process for different types of fibers. [0003] At present, most wool nitrile dyeing processes generally carry out soaping treatment and multiple cleaning treatments during the post-treatment process of wool nitrile skein yarn. At present, because the cleanliness of the dyeing water after dyeing is difficult to control, the dyeing water will be discharged and re- Add clean water, then pour in an appropriate amount of soaping agent, and then soap the wool nitr...
