Abstract

UN INCREMENTO SIGNIFICANTE EN EL INDICE DE PRODUCCION DE FIBRAS HUECAS POROSAS SIMETRICAS DE ALTA CALIDAD SE PUEDE OBTENER AL SELECCIONAR LAS MATERIAS PRIMAS, EL EQUIPAMIENTO Y LAS CONDICIONES DE PROCESO. EN PARTICULAR, LA SELECCION DE CONCENTRADOS DE POLIMERO, SOLUCIONES PRECIPITADORAS Y LAS DIMENSIONES DEL TINTE DE FIBRA SON IMPORTANTES PARA LOGRAR UNA VELOCIDAD DE PRODUCCION MAYOR DE 30 METROS POR MINUTO. EN EL PROCESO, UNA SOLUCION ESTIMULANTE POLIMERICA (12) SE FILTRA A TRAVES DE UNA PRENSA FILTRO (16) Y SE CONDUCE A UN APARATO DE HILADO HUMEDO DE INYECCION EN SECO (20) CON UNA SOLUCION PRECIPITADORA (22). LAS SOLUCIONES (12,22) CENTRIFUGAN EN EL APARATO (20) PARA FORMAR UNA FIBRA QUE SE TEMPLA Y BOBINA EN UNA RUEDA (40). EL PRODUCTO DEL PROCESO DE LA INVENCION ES UNA FIBRA DE ALTA CALIDAD QUE PUEDE USARSE EN GRAN VARIEDAD DE USOS MEDICOS INCLUYENDO DIALISISRENALES, FILTRACIONES DE SANGRE, ETC.
