Abstract (en)

[origin: DE19600572A1] The invention relates to a process for producing flexible cellulose fibres by spinning solutions of the cellulose through spinnerets over an air layer in an amine oxide-containing aqueous and/or alcoholic regenerating bath followed by drying, in which the damp threads from the spinneret are taken before drying through at least one post-treatment bath containing water and water-miscible alkanols, diols, triols or mixtures thereof, and a washing bath containing water, an alkanol, a diol or a triol.
