PROCESS FOR PRODUCTION OF OXIDISED CELLULOSE PULP

摘要

The present invention relates to a process for producing an oxidised cellulose pulp fibrillar network comprising the following steps: (a) oxidising a cellulose pulp to obtain about 0.3 to 2.5 mmol carboxylic groups per gram cellulose pulp; and about 0.1 to 5.0 mmol aldehyde groups per gram cellulose pulp; and (b) homogenisation of the cellulose pulp of step (a) wherein the cellulose fibres are refined to provide a cellulose pulp comprising 0-50 % of fibres having an average length 0.7 mm - 2.1 mm; and 50-100 % of fibres having a particle size of 0.05 -500 micrometer (µm). Also step (c) drying of the cellulose pulp obtained by step (b) may be included in the process.
