Abstract
La invencion se refiere a un procedimiento para la produccion de una suspension de celulosa en un oxido de amina terciaria, acuoso, líquido, en donde la celulosa desmenuzada es mezclada con dicho oxido de amina terciaria, acuoso, líquido, dicho procedimiento comprendiendo: A) poner en contacto la celulosa desmenuzada con el oxido de amina terciaria, acuoso líquido, siendo preparada una primera mezcla y B) esparcir esta primera mezcla mecánicamente como una capa sobre una superficie y transportarla a lo largo de esta superficie mientras está siendo mezclada en forma intensiva, hasta que se produce una suspension homogénea que es removida de la superficie, en donde (C) las mediciones de (A) y (B) se llevan a cabo en forma continua.
