Synthrapol is a mild soap specifically made for removing excess dye so
that dried articles may be washed with other laundry. When dyeing not
all of the dye will react with the fiber being dyed. Excess dye, therefore,
must be removed to prevent backstaining. Rinse the fiber as thoroughly
as possible with a small amount of Synthrapol, then launder with one
tablespoon per load. Synthapol suspends and carries the excess dye
from the fiber.
