Abstract:
1. A process for producing an oxidised cellulose pulp fibrillar network, comprising: (a) oxidising a cellulose pulp with an oxidising agent to obtain about 0.5 to about 2.2 mmol carboxylic groups per gram of the cellulose pulp; and about 0.1 to 5.0 mmol aldehyde groups per gram of the cellulose pulp; (b) homogenisation of the cellulose pulp of step (a) wherein cellulose fibres of the cellulose pulp are refined to provide 0-50% of the cellulose fibres having a ‘Kajaani fibre length’ of 0.7 mm-2.1 mm; and 50-100% of the cellulose fibres having a ‘Malvern particle size’ of 0.05-500 micrometer (μm); and optionally (c) combining with lignocellulosic fibres.
