Patent abstract
Process for manufacture of cellulose mouldings, such as fibres, filaments, or films, from TCF-bleached or ECF-bleached cellulose, in which the bleached cellulose is dissolved in an aqueous tertiary aminoxide to form a mouldable cellulose, the cellulose solution deforms, and the moulding comes into being by coagulation of the deformed solution, characterized in that, to reduce the cellulose decomposition in the process, TCF-bleached cellulose is used comprising carboxyl group content in the range from 1 to 35 μmol/g or an ECF-bleached cellulose with carboxyl group content in the range from 1 to 50 μmol/g. Cellulose mouldings having a reduced cellulose decomposition may be formed by said process.
