I just dyed some hemp cotton blend fabrics using the rust orange colored Jacquard dye. I used the ratio of 1 tbsp. dye to a 3 gallon bucket of water with 1.5 cups salt and 1/3 cup soda ash which would fall under the medium color range on Jacquard's site. I let the fabric soak for about 45 minutes. The fabric turned out a light peachy color instead of the terracotta/rust orange I was after.
So is it best to re-dye using the same ratio of dye/soda ash/salt? Or should I double the dye and increase the soda ash and salt quantities? Soak longer?
Thanks in advance for any advise!
