Soda Ash = sodium hydrogen carbonate
It's used as a fixative for the dye. You can buy it in craft stores, online at Dharma Trading Company or ProChemical and Dye Company. Those are all more expensive than where I got my 4.25 lbs. pail though. I got it at Menards in the pool isle. It's used to raise the alkalinity in your pool. Menards is a home building supplies store, like Home Depot or Lowes.
If you are using Procion dyes, you should follow the instructions that both Dharma Trading Co. & Pro Chemical and Dye provide on their websites. In order for the dye to do it's job you need to leave it for 24 hours. Soda ash is either mixed with the dye bath or mixed with water and the fabric soaks in it for 20 min., before going in the dye bath. Just look up on those websites for their instructions.
