Chemical process

Šmykľavka: 1
2. Yeah, I read that disperse dyes have the smallest molecules among all the common dye classes.
1. Hey, have you guys ever looked into the chemistry of disperse dyes?
3. Really? Why’s that important?
4. It helps them penetrate synthetic fibers more easily. Also, one key thing is that disperse dyes don’t have polar groups, which is why they’re insoluble in water.
Šmykľavka: 2
5. Right, that makes sense. No polar groups, so they need a dispersing agent to work in water. But do you know what types of chemical structures they mostly have?
7. That’s true, and then you’ve got anthraquinone-based dyes, which make up about 15%.
6. Actually, I do! Monoazo compounds make up around 80% of disperse dyes. It’s the dominant structure in this class.
Šmykľavka: 3
9. Exactly. But it’s the monoazo types that are the majority, which is why most disperse dyes are derived from them.
8. And the remaining 5%? Those are other structures, right?
10. I guess that explains why disperse dyes are so effective on synthetic fabrics like polyester—they’re small, non-polar, and perfectly suited for the job.
