Abstract

Patente de Invenção: <B>"PROCESSO PARA A PREPARAçãO DE FIBRAS DE CELULOSE E DISPOSITIVO PARA EFETUAR O PROCESSO"<D>. Para a preparação de fibras de celulose, uma solução de celulose em um óxido de amina terciária é conformada a quente para a produção de filamentos, os filamentos são resfriados e são a seguir introduzidos em um banho de precipitação para precipitar a celulose dissolvida, pelo que a solução conformada é exposta a uma corrente de gás essencialmente laminar (figura 2a) para resfriamento antes de sua introdução no banho de precipitação.
