Zusammenfassung:PCT No. PCT/DE96/02190 Sec. 371 Date Dec. 14, 1998 Sec. 102(e) Date Dec. 14, 1998 PCT Filed Nov. 13, 1996 PCT Pub. No. WO97/25462 PCT Pub. Date Jul. 17, 1997The 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.
