※Figure for absorption efficiency is when dyeing with waste paper pulp and alum for 0.3% (o.w.p.)
※Caution
- When dissolved in hard water, dye may become precipitated if left for a long time after cooling. Adding sodium phosphate improves solubility and brightness.
- Using with positive ionic substances may cause precipitation. Do not mix with basic dye if possible.
- For use on waste papers, inject to beater, mixing chest and machine chest as a solvent after deinking process.
