Dyespin™ Plus. This black is made with six different dyes. For the traditional reactive dyeing process you will need dye powder, soda ash, urea (opt.), fabric detergent (opt.), dust mask, gloves, and safety glasses. Dye Mixing: For the color swatch, we used 3 tsp Epic Black dye powder to 1/2 cup warm water with 1/2 tsp urea.
