Dispersible cation

Contact with dyes has been for many years, because they have been dye factories, companies to do dye analysis, testing, proofing, color, application of the work, so the dye is also a soft spot. The first knowledge of cationic dyes was about 15 years ago, and it was not very well understood at that time.

Cationic dyes are currently widely used in two categories, one is the common type of cationic dyes, it is worthy of the name, in the solution with a positive charge, that is, cationic; The other is a dispersed cationic dye, which is the product of ordinary cationic dyes after commercial processing, it exists in the solution with a negative charge, that is, anionic, in my eyes it is what I want to say "shemie", because many people in the actual application do not know whether it is "male" or "female".

Dispersible cationic dyes are characterized by simple dissolution, warm water can be, it is generally recommended that the water temperature be controlled at about 50 ° C, and the pollution is small, the levelling property is good, the solution is anion, so that it can be dyed with disperse dyes, reactive dyes, acidic dyes, direct dyes, without any problems. In particular, the rise of CDP of modified polyester has made dispersible cationic dyes better applied. Recently in the fabric market, CDP/PET curtains, sofas, sports shoes, clothing and other fabrics are dyed with dispersed cationic dyes and disperse dyes in one bath to achieve different style effects.

In the application of dispersed cationic dyes, the biggest misunderstanding is that many times, users simply think that it is a cationic dye, mixed with ordinary cationic dyes and cationic auxiliaries, and then it will inevitably occur a variety of dyeing problems such as dye spots and color spots. In addition, when it is dissolved, its identity is also not clear, and it is dissolved with steam or hot water, which destroys the structure of dispersed cationic dyes, which will also lead to many production problems.

Dispersible cationic dyes are currently more famous on the market is the Japanese chemical Kayacryl ED type, the domestic SD type, and the names of other manufacturers are different, we must understand its properties when using, so as to better use.

Small partners engaged in proofing and dyeing, when you encounter cationic dyes, please be sure to remember that there are "men" and "women" in this dye. Dispersible cationic dyes are the "girl" that stands out, because dispersive, active, acidic, and direct dyes are all "partners" that they can play with. This makes it easy to dye blended fabrics, and there are many possibilities.

Dye fills the world with color, and the dyeing work is the dancer of color.
