Synthrapol® is an industrial strength, pH neutral, liquid detergent used as a prewash and afterwash for dyed or painted fabrics and as a wetting agent for fabric dyes and paints. Synthrapol® has the unique property of keeping loose dye suspended during washing, thus preventing backstaining while aiding in the removal of excess color.
Prewash:
Prewashing fabric with Synthrapol® to remove oils, waxes, starches and sizings helps ensure an even dye job and reduces the risk of blotchy color. Directions: Add 3 tablespoons/44 ml Synthrapol per 8 lb/3.63 kg washing load. For cotton and other cellulose fibers, add 2 tablespoons/30 g soda ash. Wash for at least 10 minutes using hot water and then rinse thoroughly.
Afterwash:
Synthrapol® helps keep loose dye in suspension and is used to remove excess color and prevent backstaining. Directions: After dyeing or painting, rinse fabric in cold water and then wash for at least 10 minutes using 3 tablespoons/44 ml Synthrapol® per 8 lb/3.63 kg fabric. Use hot water for cotton, cool to warm water for silk and wool, and then rinse thoroughly in cold water.
Wetting Agent:
Adding Synthrapol® to a dye bath or fabric paint can increase dye penetration and helps ensure even coloring. Directions: When dyeing wool and other hard-to-wet fibers, add 2 to 3 drops Synthrapol® per 5 lb/2.27 kg fabric.
To increase the penetration, coverage and adhesion of fabric paints on hard-to-wet fabrics, add 1 to 2 drops Synthrapol® per 2 fl oz/59.15 ml paint.
