A wool or the like fiber scour including at least one of the following, (a) scouring process wherein the fiber is subjected to an acid extraction process to remove absorbed iron, and by to greatly improve the brightness (Y tristimulus value) of the wool; (b) a scouring process wherein a bleaching process is carried out part way through the wet process following by dying, rewriting and chemical reduction, therefore stabilising the bleached color to prevent subsequent reversion in the dyebath; or (c) a scouring process wherein scoured clean fiber is dried and dusted, and then reimmersed in liquors containing detergents and dispersants, thereby effectively removing extra amounts of residual dirt. The scour produces an improved quality of fibres.
