Abstract
Described are methods of manufacturing a cellulose-acetate bundle, the filaments making up the bundle being produced by extruding a solution containing, in addition to cellulose-(2,5)-acetate and solvent, non-toxic compounds which are only slightly soluble in the solution and whose molecular diameter is at least 30 % less than the diameter of the filaments. Water-soluble or bacteriologically degradable organic compounds, in particular starch, starch derivatives or dextrins, are used as the additives.
