A process for treating the surface of cellulosic shaped products such as fibers, films, filaments, yarns and the like, formed from a spinning dope of a solution of cellulose in amine oxide, comprises applying to the surface of the product after extrusion and prior to contact with each other a nonsolvent liquid that will reduce the solvent action of the amine oxide for cellulose at the surface of the product. Nonsolvents include 1-5C alcohols and on electrical charge may be induced onto the surface of the product prior to coating. Filaments may be stretched after extrusion. |
