PROCESS FOR MANUFACTURE OF CELLULOSE MOULDINGS, SUCH AS FIBRES, FILAMENTS, OR FILM, 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.
