Abstract

The invention relates to continuous processes for preparing dimethylformamide-insoluble acrylic filaments and fibers which incur a weight loss of at most 20, preferably 15% on being heated up to 400 DEG C., by spinning appropriate polymer solutions, treating the filament bundles obtained before the first drying or heating stage in a continuous manner with an aqueous solution containing copper(I) ions, thermally fixing the copper content, and heating the bundles to 200 DEG to 350 DEG C.
