Abstract

EL INVENTO PROPORCIONA UN METODO PARA FABRICAR FIBRA DE POLIAMIDA CON UN ALTO PESO MOLECULAR Y/O RESISTENCIA QUIMICA Y TERMICA UTILIZANDO EXPULSORES DE TORNILLO UNICOS O GEMELOS. EL PROCESO INCLUYE: MEZCLA FUNDIDA DE UNA POLIAMIDA Y UN POLIMERO QUE CONTENGA AL MENOS ALREDEDOR DEL 75% DE PESO DE POLI(ADIPAMIDA DE HEXAMETILENO) O POLI({EP}-CAPROAMIDA) Y TENGA UN ACIDO FORMICA DE VISCOSIDAD RELATIVA ENTRE SOBRE 20 Y ALREDEDOR DE 50 CON UN ADITIVO DE POLIAMIDA CONCENTRADO QUE CONTENGA POLIMERO DE POLIAMIDA Y UN ADITIVO SELECCIONADO ENTRE LA CLASE FORMADA POR ESTABILIZADORES, CATALIZADORES Y MEZCLAS DE LOS MISMOS PARA FORMAR UN POLIMERO FUNDIDO QUE CONTENGA ALREDEDOR DE 0.005 A ALREDEDOR DE 2 PORCIENTO DEL PESO DEL ADITIVO; Y SACAR EL POLIMERO FUNDIDO DE UN HILADOR Y FORMAR UN AFIBRA QUE TENGA UN PESO POR FILAMENTO DE 1 A 40. LAS FIBRAS HECHAS POR ESTE PROCESO TIENEN GRAN UTILIDAD................A LAS QUE PROPORCIONAN MEJORADA RESISTENCIA AL USO Y/O AGRESION QUIMICA.
