Alkanet Root Dye Recipe for Linen, Cotton and Cellulose Fibres
for 100 grams of fibre
20 grams Alkanet Root Rhubarb Dye Powder
Soak the Alkanet in a glass jar overnight with a bit of alcohol. This helps to release the dye pigment from the Alkanet. I leave the jar outside as the alcohol fumes can be overpowering and flammable.
The following day Put Alkanet Root into dye pot filled with water.
Let simmer in dyepot for +1 hour at 50 deg.
Add pre-mordanted wool yarn and sample fabrics.
Let simmer in dyepot for +1 hour.
Remove the wool yarn. Let this cool and rinse thoroughly to remove the excess dye powder.
Turn the heat off the dyepot and leave the linen and cotton samples to soak overnight. More colour will continue to develop as the dyebath cools.
All cellulose fibres, yarns and fabrics must be scoured prior to mordanting or dyeing. Please see my previous article on how to do this.
How to Scour Linen
For these samples, I used several different linen and cotton fabrics as well as wool yarn.
Natural Linen (light weight)
