Abstract

Patente de Invenção:<B>"PROCESSO PARA A PREPARAçãO DE SOLUçõES DE CELULOSE"<D>. Processo para a preparação de uma solução de celulose moldável em um aminóxido terciário contendo água, caracterizado pela combinação das etapas de que (a) materiais celulósicos pré-triturados são introduzidos em uma solução aquosa de um aminóxido terciário, para preparar uma primeira suspensão com uma densidade da substância seca de, pelo menos, 10% em massa de celulose, (b) a primeira suspensão é submetida a uma moagem de alta consistência, sendo obtida uma segunda suspensão e (c) a segunda suspensão e transferida sob adução de calor sob baixa pressão na solução moldável de celulose.
