JACQUARD DYE FOR FELT AND WOOL 450 g

Dye for hard-to-dye protein fibres such as wool, mohair, feathers and more. The colours have been specially selected for their colourfastness and affinity for wool. Unlike typical acid dyes, SuperFast Acid Dyes are all premetallised (also known as "metal complex dyes"). Premetallised dyes fix faster than any other dye and are considered to have maximum wash-fastness and lightfastness, making them especially suitable for wool.
These colours dye more easily and do not migrate once fixed.
Because the dye molecules are complexed with metals (usually cobalt, copper or chromium), the molecules are especially large and heavy, which is what gives them their unique electrochemical properties. However, this does not mean they are unsafe or bad for the environment when used correctly.
