Abstract
"PROCESSO PARA A PREPARAçãO DE FIBRAS CONSTITUìDAS DE POLITETRAMETILENOADIPAMIDA E MATERIAL DE FIBRAS CONSTITUìDO DE POLITETRAMETILENOADIPAMIDA". Em um processo para a preparação de fibras de politetrametilenoadipamida (poliamida 4.6) utiliza-se pelotas prensadas constituídas de pó de polímero como material inicial. Desta forma torna-se possível uma fiação isenta de problemas com a poliamida 4.6.
