Jacquard Synthrapol is a professional textile detergent formulated to clean and prepare fabrics before and after dyeing. Used as a pre-wash, it removes oils, sizing, and manufacturing residues that can interfere with dye absorption. After dyeing, it effectively removes excess, unfixed dye from the fabric surface, preventing backstaining or dull colours.

Synthrapol is gentle yet highly effective on natural and synthetic fibres, ensuring colours remain crisp, bright, and permanent. It’s a staple in any textile studio or dyeing workshop, helping to maintain quality and consistency across projects.

Benefits

Using Synthrapol ensures every dyeing project starts and ends with clean, reliable results. It enhances dye uptake, prevents colour transfer, and helps maintain the brilliance of finished fabrics.

Perfect For:

• Pre-treating fabrics before dyeing or painting
  
• Post-dye washing to remove unfixed dye
  
• Studio and classroom dyeing setups

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.
