Alum (potash alum) is a traditional mordant that helps dyes bind to fibre. Ratios vary by fibre and dye – treat this as a starting trial, not a production recipe.
Steps
- Dissolve 20 g alum powder in 1 L warm water.
- Wet scour fibre, then soak in the mordant bath with gentle heat as your dye protocol requires.
- Rinse lightly and proceed to the dye bath.
