Abstract

The invention discloses a dyeing technology of acrylon. The dyeing technology comprises the steps of putting a to-be-dyed acrylic fabric into a working solution containing 1.5% anionic dye and a 0.3% retarding agent MOB at the room temperature; adjusting the pH value of dye bath to be 4-4.5 with acetic acid, heating up to 100 DEG C at the speed of 1.5 DEG C / min, carrying out heat-preservation dyeing for 40-60 minutes, then cooling to 60 DEG C from 100 DEG C at the speed of 1 DEG C / minute, and carrying out heat preservation for 30 minutes; soaking the acrylic fabric in a mixed solution of sodium carbonate and a detergent with the temperature of 100 DEG C, and carrying out heat preservation for 60 minutes; and washing, dewatering and drying. In the dyeing process, the switching rates of an auxiliary agent and dye are stable, so that the dyeing defect and dyeing blockage can be avoided; the dyeing can be smoothly carried out as long as the boiling dyeing time is well controlled, so that the dyeing technology is convenient to operate.

Description

[0001] technical field

[0002] The invention belongs to a dyeing process, in particular to an acrylic fiber dyeing process.

[0003] Background technique

[0004] When dyeing traditional acrylic fabrics, the dosage of anionic dyes is 1.5%, retarder 1227 is 1%, and acetic acid is used to adjust the pH value of the dye bath to 4-4.5. The dyeing process adopts a step-by-step heating method, that is, after adding materials, the temperature is gradually raised to 86°C, the temperature is kept for 15 minutes, and then the temperature is raised to 100°C for 30 minutes. Although the operation is cautious, there are still color flowers. Contents of the invention

[0005] In order to overcome the above-mentioned defects in the prior art, the object of the present invention is to provide an acrylic dyeing process with good dyeing effect and colorless flowers appearing.

[0006] Acrylic fiber dyeing process provided by the invention, its processing step is as follows:
