| Abstract | ProceSS for producing formed cellulosic articles, particularly fibers and filaments, comprising a) dissolving cellulose in an aqueous Solution of a tertiary amine oxide, especially N-methyl-morpholine N-oxide, and b) extruding the cellu lose Solution through an extrusion die Via an air gap into a precipitation bath with precipitation of the formed articles, Said cellulose Solution and/or said precipitation bath con taining a tenside, characterized in that in the step b) the tenside content c of the cellulose Solution and/or of the precipitation bath is in the range 100 ppmdcd5 ppm, and the width of the air gap is in the range from 2 to 20 mm. With this process the air gap width can be considerably reduced without deterioration of the properties of the fibers/ filaments. |
