Soda Ash for Tie-Dye – EVERYTHING you need to know

Soda ash is sodium carbonate – Na 2 CO 3. In tie-dyeing, soda ash helps the dye to stick. It enables the dye molecules to bond permanently with the fabric molecules by providing an alkaline pH of 10.5 – 11. So whenever you use soda ash you have to think of how it's reaching both the dye and the fabric, and helping the dye stick to the fabric.
