Dupont Alter Ego dyes for cellulose plant fibres including cotton, viscose and linen. The dye can be used two ways:
For dyeing cellulose, the dye can be used in a dye bath by diluting at a ratio of 15ml to 1 litre of warm water. Dissolve 10g of coarse salt and 20g soda ash (steam fixing is an alternative to using soda ash) in the warm water and stir in the dye. Rinse out your fabric or fibres in water and squeeze out the excess. Immerse the material in the dye bath while still wet and gently heat for 5 minutes before increasing to a boil, stirring regularly. Switch off the heat and leave to stand for 10 minutes. Remove any residue dye by rinsing in a solution of synthrapol (or washing powder) and then clean water until clear.
Double dyeing with Dupont Alter Ego dyes and Dupont Classic dyes (in the same dye bath) is the exciting technique of dyeing materials, which contain both cellulose and protein fibre, two different colours in one go! This method works particularly well for dyeing devore fabric which has a silk (protein) backing and a viscose (cellulose) pile.
The method for double dyeing is:
To dye 25-35g material you will need 10ml of Alter Ego per 1 litre of water, 5ml of Classic, 6 drops of Alter Ego Fixative and 3 drops of vinegar, 5ml of coarse salt. Stir the ingredients into a pan of warm water, rinse the fabric, wring out and immerse it still wet in the mixture. Stir over the heat for 5 minutes. Heat to boiling. Let it boil for 5 minutes. Remove the pan from the heat and let it cool for 10 minutes. Rinse the fabric with water and then wash with warm water and soap. It is possible that one of the darker colours takes over and influences, even very slightly the lighter colour. Allow to dry before setting in a steamer or microwave.
