Abstract

PROCEDIMIENTO PARA LA PRODUCCION SIMULTANEA DE UNA PLURALIDAD DE FILAMENTOS DE POLIAMIDAS AROMATICAS DE GRAN RESISTENCIA Y ELEVADO MODULO, A PARTIR DE POLIAMIDAS AROMATICAS CON ENLACES PROLONGADORES DE CADENAS QUE SON COAXIALES Y PARALELOS Y ESTAN DIRIGIDOS EN SENTIDOS OPUESTOS. COMPRENDE LAS SIGUIENTES OPERACIONES: PRIMERA, SE ALIMENTAN CANTIDADES SUSTANCIALMENTE UNIFORMES DE UNA SOLUCION ANISOTROPA, A UNA PLURALIDAD DE APERTURAS PRACTICADAS EN UNA PLACA DE HILERA; SEGUNDA, SE EXTRUYE DICHA SOLUCION ANISOTROPA EN SENTIDO DESCENDENTE A TRAVES DE LA PLURALIDAD DE APERTURAS, PARA FORMAR UNA SOLA URDIMBRE VERTICAL; Y POR ULTIMO, SE COAGULA LA SOLUCION ANISOTROPA EXTRUIDA DESPUES DE ATRAVESAR LA CAPA DE FLUIDO NO COAGULANTE.
