Abstract

La invencion se refiere a un procedimiento para la produccion de cuerpos de celulosa moldeados que exhiben brillo alto, que se caracteriza por una combinacion de pasos de: blanquear la pulpa usando un agente blanqueador, siempre y cuando el agente blanqueador no contenga cloro o ningun compuesto de cloro; disolver la pulpa blanqueada usando el agente blanqueador en un oxido de amina terciaria acuoso, una solucion de celulosa moldeable siendo obtenida; y procesar la solucion de celulosa moldeable en cuerpos moldeados.
