phosphate-free acid donor slowly releases acid in the hot dyebath down to pH 3.
When dyeing polyamide fibres and wool with acid, reactive chrome and metal complex dyes, the controlled lowering of the pH permits starting the dyeing process in the alkaline pH region where the dyes exhibit the least adsorption and the best migration.
This method allows perfect levelness to be achieved even with highly build-up byes,or with rapid fibres.
the low pH values attainable with Sandacid VS Liq also permits complete exhaustion of acid dyes,thus ensuring maximom reproducibility. |
