    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.

    摘要: Mixtures of various starch-degrading enzymes (amylases) which comprise at least one high temperature amylase (HTA) and at least one low temperature amylase (LTA) in an activity ratio of HTA to LTA of 10%:90% to 90%:10% develop at least 60% of their maximum activity in the temperature range from 30.degree. to 90.degree. C. Such mixtures can be diluted with water and treated with customary additives. These mixtures are suitable for desizing textiles sized with starch by treatment of the textiles with the mixtures mentioned and subsequent rinsing.
