Abstract

The invention relates to a process for producing cellulose moulded articles of high brightness, the process being characterised by the following combination of measures: pulp is bleached with a bleaching agent which must not contain chlorine or any chlorine compound; the pulp once bleached is dissolved in an aqueous tertiary amine oxide to produce a mouldable cellulose solution; and the mouldable cellulose solution is worked into moulded articles.
