Dyeing process of active dye

Abstract

The invention discloses a dyeing process of active dye. The process comprises the following steps: drying active dye, and then standing at room temperature for 5 minutes; adding a dye leveler; adding a dispersing agent; heating to 40 DEG C; soaking the dye which is processed with clear water for 30 minutes; keeping the temperature for 20 minutes; adding 30% of mirabilite and soaking for 20 minutes; adding 60% of mirabilite and soaking for 10 minutes; heating to 60 DEG C; keeping the temperature for 10 minutes; adding 2% of sodium carbonate and soaking for 20 minutes; adding 8% of sodium carbonate and soaking for 20 minutes; adding 15% of sodium carbonate and soaking for 2 0 minutes; keeping the temperature for 40 minutes; flushing with cold water for 10 minutes; adding glacial acetic acid; flushing with hot water of 80 DEG C for 15 minutes; soaping twice; flushing with hot water for 15 minutes; neutralizing; carrying out fixation; softening; carrying out post-treatment; and discharging the cloth. According to the dyeing process of the active dye disclosed by the invention, after the dye is added, the dye is uniformly attached to the fabric; the mirabilite is added in batches; the salinity in the dye liquid is not too high; color points are prevented from being separated out on the fabric surface; the time interval of adding an additive is prolonged; the adsorption diffusion process of the dye is prolonged; dye molecules in the dye bath can be relatively fully diffused and adsorbed into the fiber; the dye concentration in the dye bath is lowered; the trend of agglomeration of the dye molecules is lowered; and high color fastness is ensured.

Description

technical field [0001] The invention relates to a dyeing process of reactive dyes, in particular to a dyeing process of reactive dyes containing turquoise blue. Background technique [0002] When the dyeing process is carried out with Cui Lan reactive dyes, the process is to add Glauber's salt first and then add the dye, which will easily cause the salt concentration in the dye solution to be too high and cause the dye to precipitate on the cloth surface to form color flowers and color spots. , although in the dyeing process will use turtle compound dispersant, and adopt methods such as adding salt and alkali in multiple steps, and the heating rate is extremely slow, but the probability of color flower is still very high, so it is necessary to strip the color and then re-dye. But in this way, the fastness is poor and the washing water is not clean. Contents of the invention [0003] In view of the above-mentioned technical problems, the object of the present invention is ...
