Abstract

A process is disclosed for preparing a homogeneous suspension of cellulose in an aqueous solution of a tertiary amine oxide. Cellulose is mixed with the aqueous solution of tertiary amine oxide in a mixer which has a container for accommodating the suspension and a mixing tool. This process is characterised by the use of a mixer with a container which rotates during the mixing process.
