METHOD FOR THE HYDROPHILIC PROCESSING OF CELLULOSE FIBRE AND PRODUCTION METHOD FOR HYDROPHILIC CELLULOSE FIBRE

WIPO Patent Application WO/2011/024807

A1

Disclosed is a processing method for making cellulose fibres hydrophilic, whilst limiting losses in colour and strength. The hydrophilic processing method comprises a first oxidation step, whereby cellulose fibres are oxidised in a first reaction solution that includes an N-oxyl compound and a re-oxidising agent for said N-oxyl compound, and a second oxidation step, whereby the oxidised cellulose resulting from the first oxidation step is oxidised in a reaction solution that includes an oxidising agent that oxidises aldehyde groups.
