Scouring natural fibres

Scouring is a very important step in the dyeing process. Missing this step can result in patchy weak colour bonds and disappointing outcomes.

Scouring is the deep-cleaning process used to prepare natural fibres, cotton, wool, linen, and silk before dyeing. It removes oils, waxes, dirt, and processing residues that prevent dyes from bonding evenly. By gently simmering fibres in hot water with a mild alkaline soap or detergent, scouring opens the fibre structure, improves absorbency, and ensures brighter, more consistent colour results in natural dyeing.

Each fibre has it's own personality in terms of it's strengths and weaknesses so it's important to get to know how to treat each one individually during the dye process. Wool and silk should not be heated above 60C to avoid felting and damaging the fibres. Also, you don't want to shock it with extreme temperature changes.
