ABSTRACT:
A process is disclosed for the preparation of a shapeable solution of cellulose in an aqueous tertiary amine-oxide from comminuted cellulose. The process includes introducing previously comminuted cellulose material into an aqueous solution of a tertiary amine-oxide to prepare an initial suspension, subjecting the initial suspension to high-consistency milling to further break-up the cellulose material to obtain a second suspension, and converting the second suspension into a shapeable solution of cellulose by heating under reduced pressure.
