Abstract

a presente invenção se refere a um método de formação de uma solução aquosa compreendendo celulose microfibrilada, o método compreendendo as etapas de provisão de um material compósito substancialmente seco, compreendendo celulose microfibrilada e um material de enchimento, em que referido material de enchimento é precipitado em cima de fibras ou de fibrilas de referida celulose microfibrilada; provisão de um meio aquoso, em que o método adicionalmente compreende a etapa de abaixamento do valor de ph de referido meio aquoso, e então, misturação de referido meio aquoso com referido material compósito substancialmente seco, de maneira tal que o material de enchimento é liberado a partir de referida celulose microfibrilada, assim dissolvendo referida celulose microfibrilada; ou a etapa de misturação de referido meio aquoso com referido material compósito substancialmente seco, e então, abaixamento do ph de referida mistura, de maneira tal que o material de enchimento é liberado a partir de referida celulose microfibrilada, assim, liberando referida celulose microfibrilada.
