Beschreibung
Zusammenfassung:	A method of producing shaped articles e.g. fibres and fibres of regenerated cellulose comprises dissolving in organic solvents O- trimethylsilyl (O-TMS) celluloses of the general formula wherein n denotes the mean average degree of polymerisation and stands for the numerical values 30 to 3,000 and R means hydrogen or trimethylsilyl provided that the degree of substitution amounts to 1 to 3, converting the solution into shaped articles, quantitatively desilylating the articles either slmultanesouly or in a subsequent working step in the presence of at least stoichiometric amounts of water, preferably in an acidic medium and, if desired, subjecting the products obtained to an after-treatment.
