Abstract

A method for the production of cellulose fibers or filaments from cell material, by the dry-wet extrusion method with aqueous amine oxides, in particular, N-methylmorpholine-N-oxide as solve is described comprising the following steps: a) dispersion of a cell material, or a cell material mixture with a cuoxam DP from 250-3000, in aqueous amine oxide, b) transformation of the obtained dispersion, by water evaporation with shear, at elevated temperature, into a homogeneous solution with a zero shear viscosity of 600 to 6000 Pa.s and a relaxation time of 0.3 to 50 seconds all at 85° C., c) feeding the solution to a spinning jet, previous to which it is passed through flow chamber prior the jet(s), in which the retention time at the spinning temperature, d) forming the solution into at least one capillary in each spinning jet, drawing the capillary(ies) from each jet through anon-precipitating medium and then precipitating the cellulose fibers on drawing through a precipitating bath and e) at the end of the precipitating bath section drawing off the fibers by deflecting the precipitation flow. In stage d) the capillary bundle(s) are treated with a gas flow, just before the entry thereof into the precipitating bath, at an angle alpha to the capillary flow, wherein 45°<alpha<90°.
