Linen and cotton yarns require a different mordant preparation prior to using natural dyes.
- Use clean, scoured wool or yarn.
- Fill a large pot with clean water and heat.
- Weigh the yarn or clean, dry fleece.
- Using 20% Alum to weight of fibre, mix the Alum into the hot water.
- Using 10% Tara Powder to weight of fibre, place the Tara Powder into a nylon stocking or small bag. Add it to the hot water mixture.
- Rinse the wool so that it is damp.
- Add the wool or skeins of yarn into the hot Alum/Tara mixture.
- Make sure that the wool is all covered by the water, if not, add more water to the pot.
- Simmer the mordant mixture for x-about an hour at 90 degrees Celsius.
- Remove the yarns from the mordant mixture.
- The Alum/Tara mixture can be reused by adding 1/2 the amount of Alum and Tara powder as previously
- If dyeing skeins of yarn, make sure that the skeins are tied securely, but loosely in at least 3 places, to avoid tangling.
- The mordanted yarns can be dyed immediately, or dried and stored for later natural dyeing.
- The mordant is suitable for cottons, linens and other bast fibres.How To
