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.

Innovation is Ernest Solvay's legacy. In 1863, Ernest Solvay invented a radically new industrial process for the production of soda ash. His technological breakthrough, known as the Solvay process or ammonia-soda process, provided a more efficient and cleaner alternative to the Leblanc process it replaced. By 1900, Solvay's innovation was ...
Soda Ash
Soda ash is used in a large number of prepared domestic products: washing powders, soaps and scouring powders where it acts primarily as a builder or water softener.

Soda Ash
The preparation of soda ash is generally done using one of four processes – the Leblanc process, the Dual-process, the Solvay process, and the Electrolytic process. Soda ash is a weak acid that is slightly soluble in ethanol and insoluble in alcohol. One of the important applications of this compound is as a water softener.
