Procion is a brand of reactive dyes, meaning the dye reacts with the cellulose fibres (plant-based fibres including cotton and linen) of fabric. A cellulose fibre will not work on protein fibre (animal-based fibres including silk and wool), it which case Acid Dye will need to be used.
I chose Procion over Acid Dye due to being a little cheaper, and the specific Procion type I bought was Procion MX, a cold water dye, what I didn’t realise was a fixer/setter is also required in this case sodium carbonate (soda ash) as this added to the price.
The procedure to dye fabrics with Procion MX is fairly straight forward, what I planned to dye black was a pink top and grey skirt.
- First fill a container with about ten litres of water, add the Procion MX dye and stir to make sure everything is dissolved and mixed evenly.
- Immense the cloths in the dye bath and stir for thirty minutes to make sure cloths are evenly dyed.
- Add the soda ash and again stir for thirty minutes to make sure soda ash is dissolved and mixed evenly.
- Remove cloths from dye bath and rinse with clean water to remove excess dye.
- Once the majority of dye is removed, it can be machine washed to remove any traces.
Enjoy the newly coloured clothes.
