Synthrapol - 16oz
**PLEASE NOTE - This product is only available for Pick Up and Drop Off.
Synthrapol is used to suspend & remove excess dye from 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.
Invisible lubricants, dirt, oil, & other impurities can interfere with the dye and cause uneven dyeing. Prewashing in Synthrapol helps remove all these before dyeing your fabric.
It is highly recommended for use as a pre wash to remove excess dye (especially in reds and blues), sizing, dirt and oils.
