TC-Acid Donor SWP

TC Surespender SWP

TC-Acid Donor SWP is used when dyeing polyamide fibres and wool with acid and metal complex dyes. Dyeing starts in the neutral to weakly alkaline medium, the most beneficial conditions for even distribution of the dye. The product leads to a gradual shift of the pH value into the acidic area, which achieves optimal exhaustion of the dyes. It is of advantage that best levelness, outstanding reproducibility and shorter dyeing times result even under very unfavorable dyeing conditions.

Properties and Advantages:
  • colourless, clear liquid
  • density approx. 1.2g/cm3
  • can be distributed with cold water in any ratio
  • Hard-water-resistant
  • Acid-resistant
  • Low-foaming
  • Effects excellent levelness, short dyeing times and high reproducibility even under unfavorable conditions
  • Alkali-sensitive
Solving recommendation:

TC-Acid Donor SWP will be added directly to the bath, right before the start of dyeing.

Amounts:
 0.2 - 2.0 ml/l TC-Acid Donor SWP
0.5 - 2.0 %  Alviron P 96 (Wool) or Alviron CNF (Polyamide)
