The main application areas of Acid Blue 80

1. Textile industry

Acid Blue 80 is mainly used for the dyeing of protein fibers (such as wool, silk) and polyamide fibers (such as nylon). It can form an ionic bond with the amino in these fibers, thus achieving a firm dyeing.

2. Paper industry

In specialty paper production, Acid Blue 80 is used to produce colored paper, especially for occasions requiring high color fastness.

3. Other industrial applications

– Leather staining
– Ink manufacturing
– Bio-dyes (limited application)

Advantages of Acid Blue 80

1. Good color fastness: especially excellent performance of light resistance and washing resistance
2. Bright color light: can produce a bright, pure blue tone
3. Good solubility: easy to prepare dyeing bath
4. Good matching: can be mixed with other acidic dyes to match different colors
