This is washing soda!! Used it in dyeing fabrics, it does controls PH in water, neutralizing acidity... also binds the dye to the fabric at molecular level apparently... permanently... Best to pre-soak the fabric in water mixed w soda ash + salt before dye process. Dyed fabric color stays brighter + less running color from fabric .... salt helps w color brightness .... each dye color apperently has its own separate 'dye+afterdye' reaction process curve advances the heat-timeline as these compounds are added to the dyebath! (Yes ... some are adding soda ash and salt directly into the dyebath - be ready to use on fabric as this way your dye is active)

I’m fairly new to tie dying but using this as a pre soak intensified my colors so beautifully! I didn’t even have to use that much but it really made my latest shirt pop! Can’t wait to make some more.

Works great.
