    摘要: Dyed fibrous materials made of or containing cellulose which were not bleached before dyeing are aftertreated in a combined bleaching and washing bath which can, optionally, contain as stabilizers derivatives of phosphonic or phosphorous acid, optionally as a combination with polyhydroxy compounds. The resulting materials have bright and brilliant shades.This aftertreatment makes it possible to by-pass the otherwise customary, time-consuming and expensive drying of the materials between a bleach before dyeing and the dyeing itself.
