    摘要: Dyed raw cellulose can be bleached in a bleaching and after-treatment bath containing, in addition to usual stabilizers, cationic-monomeric and/or polymeric compounds and, if desired, nonionic surfactants. Bleaching is carried out with the aid of aqueous-hydrogen peroxide. The stabilizers that can be used and the cationic compounds are defined in the specification. Nonionic tensides, if their co-use is desired, are those of the class polyglycolethers.
