Synthrapol Fabric Dye (000300)

Synthrapol is used to suspend and carry excess dye from cotton fiber. It removes any unfixed or unreacted dye to keep it from redepositing dye onto areas of the fabric that you don't want to be stained. It is recommended for use as a pre-wash to remove excess dye (especially in reds and blues), sizing, dirt, and oils. Please note: It only works on fiber-reactive dyes, which is generally what is used in quilting fabric. 4 oz. bottle.
