Notes: 　　　　　　　

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

2. Water containing metal ions，such as: Cu、Fe、Mn、Zn，will affect the whitening effect of OBA. For this

aspect，Can use metal ion chelating agent to remove in advance.

3. Do not exposed to the sun after dissolution.

4. CXT has good fastness to H2O2,so with H2O2 bleaching and fluorescent whitening treatment can be in the same dye bath。

5. CXT 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.Its dyeing speed is fast, dye uniformity and compatibility is good, so Room temperature bath without additives can dyeing

7. If used in the dye bath containing sodium chlorite，will effect the whitening effect, so need to remove chlorine fully before use CXT.

8. The fluorescent brightener CXT poorly soluble in water, only recommended for Exhaust, not recommended for Padding. Its aqueous solution has milk-white suspension, but does not affect the use effect.
