a Application
1.Stripping after dyeing and printing For vat dyes
Significant results can be achieved when add DA-BS800 to stripping bath of vat dyes. While the stripping effect depend on the amount of DA-BS800. Recommended dosage for stripping is as follows when in big liquid ratio.
3-5 g/L DA-BS800
As refer to deep color, suggest adding protective colloid, such as Dekol SN-S (2g/L) or dispersing agents such as Setamol WS or Uniperol AC (2g/L) to avoid precipitation. If it is hard water, we recommend adding Dekol SN-S or Trilon TB. The stripping temperature should be as high as possible, but can not exceed 85a in order to maintain the stability of the dye bath.
Recipe:
2 g/L Dekol SN-S
1-2 g/L Setamol WS or/and
1-2 g/L Uniperol AC
