摘要:Process for the production of cellulose fibres, or filaments of pulp according tothe dry - wet extrusion process with aqueous amine oxides, in particular n -methylmorpholine - n - oxide, in whicha) cellulose and aqueous amine oxide at elevatedtemperature in a mixing - / kneader reactor and dispersed under removal of water andshearing into a homogeneous solution with a zero the structural viscosity in the range of1000 – 8000 pas and a relaxation time in the range of 0,5 transferred – 80 seconds,b) thesolution of at least a spinneret, and feeds in the spinning capillaries with the strain rate ε .deformed,c) the deformed solution by means of a not ausfäll end medium with
simultaneous further deformation with the strain rate · ε . transported,d) in a precipitationbath the cellulose yarn or the - group of yarns, by deflecting over a godet separatesfrom the precipitation bath, in a multistage aftertreatment apparatus is washed in fiber -or filament form, if appropriate, bleached, and then brightened, dried, optionally
crosslinked and subsequently the filaments as yarn individually or combined, to the cablewinds..
