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 also has the unique property of keeping loose dye suspended during washing, thus limiting the dye from re-depositing on other parts of the fabric.
Prewash fabric with Synthrapol to remove oils, waxes, starches and sizing, to help ensure an even dye job and reduce the risk of blotchy color. It can also be used as a scour for oily or dirty fleeces.
Synthrapol helps keep loose dye in suspension and is used to remove excess color and prevent backstaining, making it a good choice for a first washing of a multi-colored project.
Add Synthrapol to a dye bath or fabric paint to increase dye penetration and help ensure even coloring.
General use requires about 1 teaspoon per gallon of water, with more specific instructions for various uses printed on the label. Cleaning oily fleece may require more synthrapol, or multiple washings.
