Acid Fixing Agent Cafix A-22

Product Summary

Cafix A-22 is a new product of water soluble high polymer compound which is different from Cafix A-20 and tannic acid. Before using Cafix A-20, we suggest you adjust the pH value to 5 by acetic acid or formic acid which can make Cafix A-20 works and won’t cause the fixing spot. Cafix-22 is acid base. If your usage is around 2 ~ 5%, you don’t have to add acetic acid and formic acid. Cafix A-22 can improve washing fastness and no shade change.

  1. The dosage depends on the color of dyes.

        Light color : 1 ~ 2% (o.w.f.)

        Middle color : 2 ~ 4% (o.w.f.)

        Dark color : 4 ~ 5% (o.w.f.)


  1. Application of fixing agent:

        When applying Cafix A-22 in 2 ~ 5% (o.w.f.), you don’t have to adjust pH because the pH value will be in 4.0 to 5.0.

        If the concentration lower than 1% (o.w.f.), you have to add some acetic acid and fomic acid to adjust pH.

        Fixing condition  90℃ × 20~30 minsd

        In re-dyes and strip the color process, we suggest to use 1 ~ 3 g/L ammonia and Cascour-810A(alkali soaping agent)0.5 ~ 1 g/L and 90℃  for 15 ~ 20 mins to get rid of the fixing agent.



  1. If you leveling agent for dyeing is cationic, you need to washing completely or it will cause fixing spot on the fabric.
  2. If the water hardness is very high, it will also cause fixing spot. In addition, metal salts and neutral salts usage no more than 30g/L.
