An improvement in the subject matter of the main patent is in a process for the manufacture of fiber-sheets, films and similar products by spinning viscose in acid spinning baths preferably containing sulfuric acid in which a viscose containing organic substances which are soluble in viscose and forming with viscose is used. Zinc of the temperally stable zinc chelate spinning product is spun into a spinning bath containing zinc and the freshly spun products are characterized in that a viscose is used in which one or more compounds of the formula are present as chelating agents. (see formula) ** where r1 and r represent a substituted alkyl or aryl radical or noo hydrogen. (Machine-translation by Google Translate, not legally binding)
