Synthrapol Soap


Out of Stock


Synthrapol is a neutral detergent used as a prewash to remove sizings and silk gum, as an afterwash to remove residual dyes or wetting agent to make wool and other hard to wet fibers receptive to paint and dye. It is recommended to use Synthrapol when washing hand dyed fabrics before using them in a garment or quilt, or when fabric is already quilted and bleeds onto adjacent fabric, or simply to soak fabric before dyeing.

  • Use in dyebath for even dye results
  • Use before dyeing to remove sizing and silk gum
  • Removes excess dye from hand dyed fabrics

Size: 4 fl. ounces.

Prewash: To remove sizings, oils and waxes, add 3 TBS Synthrapol + 2 TBS Soda Ash (aka washing soda found in the laundry detergent section of a grocery store) per 8 lb washing machine load. Set on hottest setting. Wash 10 minutes, and rinse thoroughly in warm water.

After Dyeing:
Rinse fabric in cold water. Wash 10 minutes in hottest water with 3 TBS Synthrapol per 8 lb washing machine load. Rinse in warm water. Repeat if necessary.

Wetting Agent:

For wool or other hard to wet fibers - add 2 or 3 drops to the dye bath
For painting hard to wet fabrics - add one drop to paint.
For marbling - add one small drop to colors to facilitate spreading on the marbling medium.
