What Synthrapol does in dyeing
Synthrapol is a specialist detergent used in textile preparation and washing after dyeing. Jacquard describes uses including prewashing and removing excess dye. Follow the exact product directions for the fiber, dye system and equipment.
Before dyeing
Preparation helps remove substances that interfere with wetting and dye uptake. The appropriate cleaning method depends on the textile and existing finish; do not assume a detergent removes every coating or stain.
After dyeing
A prescribed afterwash helps remove loose dye. That washing stage is different from fixing dye to the fiber. Synthrapol is not a universal dye fixative or a guarantee against all future fading and transfer.
Use the product-specific method
Check the selected dye’s complete preparation and washing sequence.
Use the detergent amount and water conditions specified by the manufacturer.
Respect the garment’s care and construction limits.
Do not add extra products simply because they are used in a different dye recipe.
Keep the product label and safety guidance available.
