Abstract
La presente invención trata de un proceso de producción de material de nano-celulosa basado en el uso de fraccionamiento de cadena de pulpa celulósica originada de pre-tratamiento o de desfibrilación mecánica (pulpa parcialmente refinada/desfibrada) em combinación con etapas de desfibrilación mecánica, siendo que la fracción aceptada y la fracción rechazada pueden ser destinadas a etapas de ajustes de consistencia de manera a anteceder una otra etapa de desfibrilación distinta.
