Notes:
1. Do not use cationic additives. Because may cause conflict with anionic fluorescent whitening agent.

4. optical brightener BA has good fastness to H2O2, so with H2O2 bleaching and fluorescent whitening treatment can be in the same dye bath.
5. optical brightener BA is a kind of fluorescent dyes with excellent whitening effect, Only use appropriate amount is enough to show whitening effect. If use too much will appear extinction phenomenon.
6. optical brightener BA dyeing speed is fast, dye uniformity and compatibility is good, so room temperature bath without additives can dyeing
