The invention refers to water-insoluble fibers of cellulose acetate cellulose propionate and cellulose butyrate with an extremely high absorptive capacity for water and physiological liquids and to a process for their preparation.

Water-insoluble fibers of cellulose acetate, cellulose propionate and

Molding compositions containing cellulose, 95-50% of a tertiary amine oxide, and up to 25% of a non-solvent also up to 10% of other polymers, all proportions relative to the weight of the composition and as additive, 0.01 up to 0.5% by weight, relative to the tertiary amine oxide, of an organic compound with a minimum of four carbon atoms and a minimum of two conjugated double bonds and a minimum of two groups in the form of hydroxyl and/or amino groups which, in turn, have a minimum of one unsubstituted hydrogen atom and/or contain glycerol aldehyde.
