Dylon Dyes is a company started in London in the 1940s. Dylon makes both hot water washing machine dyes, good for solid colours, and cold water dyes, perfect for tie-dyeing by hand. Cold water dyes made for plant fibres such as cotton and linen are called Procion dyes. Dylon's Procion dyes come in small plastic discs, deceptively tiny containers that impart bright, rich colours. Procion dyes can be difficult to mix at first, but by using exactly the right combination of ingredients, you can achieve vibrant results.
Wash the item you wish to dye in Synthrapol or unscented, dye-free washing powder and leave it wet.
Place the item in a bowl with just enough cold water to cover it, then remove it and wring it out.
Dissolve one packet of dye, 113 g (4 oz) of salt and 1 sachet of Cold Fix for every packet of dye. Use hot tap water and mix the dye in a cup before adding it to the water in the bowl.
Pour the mixture in the cup into the bowl.
Put the item into the bowl and stir continuously for 10 minutes.
Allow the item to soak for one hour; three hours for black.
Pour the dye into the sink and hand wash the item in cold water and Synthrapol or dye-free detergent. Hang it to dry.
Always weigh your fabric before you wash it. You will need one packet of dye for every 227g (8 oz) of dry fabric, or 113 g (4 oz) of black. If you are tie-dyeing, pour the mixture in the cup into a squirt bottle or syringe and squirt it directly onto the wet fabric. Black dye may require a second application to make the colour dark enough and solid enough. Always hand-wash dyed items in cold water and hang them to dry. This will help keep the dye from fading.
