Abstract
"PROCESSO PARA A PRODUçãO DE FIBRAS CELULóSICAS". A invenção refere-se a um processo para a produção de fibras celulósicas por extrusão de uma solução de celulose em um óxido de amina terciária através de furos de fiação de um bocal de fiação e condução dos filamentos extrudados em um banho de precipitação através de um espaço de ar enquanto estão sendo estirados, os filamentos no espaço de ar sendo expostos ao fluxo de um gás. A invenção é caracterizada pelo fato da temperatura correta (T) do gás antes do contato com os filamentos ser 60<198>C < T < 90<198>C.
