The reactive dye wet short steaming deep color dyeing method for the pure cotton cloth has the advantages that the dye and the alkaline agent solution are mixed and then are soaked, rolled, soaked, steamed and washed at one time, the working procedures are simple, the flow is short, the used equipment is few, the energy consumption is reduced, the migration is avoided, the dyeing quality is high, and the permeability, the uniformity and the flatness of the dyed cloth are all better than those of the conventional dyeing method. And the success rate of one-time lofting is high, the dyeing wastewater is less, and the method is environment-friendly.
Detailed Description
The invention is further described below in connection with the following description.
The vinyl sulfone reactive dye has high solubility and good strong alkali resistance, and is suitable for the dyeing method. The reactive dye is a multi-reactive group dye.
The pretreatment requirements of the fabric before dyeing are as follows: the cloth surface has no impurities such as sizing agent and the like; the cloth surface contains moisture uniformly; the inside and outside temperatures of the cloth surface are consistent; the capillary effect is more than or equal to 10cm/30 min; the pH value of the cloth surface is neutral.
Soft water is adopted when the reactive dye is uniformly dissolved in water to obtain the dye solution. After the reactive dye is completely dissolved, dissolving urea, a penetrating agent and a chelating dispersant in the dye solution to prepare a mixed solution. Stirring, filtering, and storing in a liquid storage barrel. The alkaline solution is filtered after being prepared and put into a liquid storage barrel for standby.
The mixing of the mixed solution and the alkaline agent solution is completed before dyeing, and the mixed solution and the alkaline agent solution are uniformly mixed according to the volume ratio of 8:2 by a proportioning pump and are input into a dye solution tank. If the mixture is mixed too early, the alkaline solution will react with the reactive dye, which will affect the dyeing effect.
The dye liquor level in the dye liquor tank can be monitored by means of a level sensor.
The method for washing, soaping and washing the cloth subjected to steaming fixation is the same as the existing dyeing post-treatment method in dyeing, and details are not given.
The room temperature in the present invention is 25 ℃ to 35 ℃.
