The present invention relates to a cellulose-containing fibrous material, wherein hydroxy groups were oxidized at the C(6) of glucose units of the cellulose into aldehyde and/or carboxy groups, a paper or nonwoven (product) made therefrom, in particular tissue (products) and a process for their manufacture. The paper or nonwoven (products) of the invention display excellent strength properties.

Oxidized cellulose-containing fibrous materials and products made therefrom

A process for oxidizing cellulose, in which a nitroxyl compound such as TEMPO is oxidized using an oxidizing agent in the presence of a complex of a transition metal such as Mn, Fe, Cu, and a complexing agent such as a polyamine, or an oxidative enzyme, and the resulting nitrosonium ion is used to selectively oxidize cellulose 6-hydroxy-methylene groups to carbaldehyde groups and carboxylic acid groups.
