Abstract

CARACTERIZADO PORQUE COMPRENDE LOS SIGUIENTES PASOS: A) LA DISOLUCION DE LA CELULOSA EN UNA SOLUCION ACUOSA DE UN OXIDO TERCIARIO DE AMINA, EN PARTICULAR DE N-OXIDO DE N-METILMORFOLINA-N PARA FORMAR UNA SOLUCION DE CELULOSA MOLDEABLE, CUYO VALOR DE pH DENTRO DE UN MARGEN CUYO LIMITE SUPERIOR Y CUYO LIMITE INFERIOR SE DEFINEN EN FUNCION DE LA CONCENTRACION DEL OXIDO TERCIARIO; B) EL MOLDEO DE LA SOLUCION ACUOSA Y LA CONDUCCION DE LAS SOLUCION DE CELULOSA MOLDEADA A UN BANO DE PRECIPITACION ACUOSA EN EL QUE SE PRECIPITA LA CELULOSA, CON LO CUAL SE FORMA UN CUERPO DE MOLDEO Y UN BANO DE PRECIPITACION USADO; Y C) LA REGENERACION DEL BANO DE PRECIPITACION USADO, FORMANDOSE UNA SOLUCION DE OXIDO DE AMINA REGENERADA, ACUOSA QUE SE USA EN EL PASO (A) DE NUEVO PARA LAS DISOLUCION DE CELULOSA
