Several major factors affecting the reactive turquoise blue staining
Analysis of influencing factors on reactive turquoise blue dyeing
In view of the reactive turquoise blue dye, the factors affecting its dyeing are discussed. As the active turquoise blue dye has high molecular weight and high direct, it is not easy to be dyed even, and it is easy to appear color stain, color flower and color fastness.
Therefore, a dye with moderate water solubility, small particles, uniform diffusion and less impurity should be selected.
At the same time, the amount of salt should be reduced as much as possible.
Check the color should be selected as alkali, soda ash fixative, charging time should not be too long;
And the use of assistants to help dissolve, diffuse and slow down the adsorption.
The hardness of the water should be controlled below 50 mg/L.
In order to avoid the problem in the process of reactive turquoise blue dyeing, it is dyed at 75~80 C.
1. from the perspective of dye, how much amount of dye, dye water soluble groups (i.e. dye solubility level), dye filling agent (dispersant, salt content, solvent) have great influence on the advantages and disadvantages of the dye molecules in the manufacturing process of the size of dye powder dissolved, expanding and leveling.
