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."PROCESS FOR THE PRODUCTION OF CELLULOSE FIBERS". The invention relates to a process for producing cellulosic fibers by extruding a cellulose solution into a tertiary amine oxide through spinning holes of a spinning nozzle and conducting extruded filaments in a precipitation bath through a airspace while being stretched, the filaments in the airspace being exposed to the flow of a gas. The invention is characterized by the fact that the correct gas temperature (T) before contact with the filaments is 60 <198> C <T <90 <198> C.
