Abstract

PROCEDIMIENTO PARA AUMENTAR EL PORCENTAJE VACIO DE FILAMENTOS HUECOS.SE PONE EN CONTACTO UN FILAMENTO HUECO (1) RECIEN FORMADO, EN ESTADO SUSTANCIALMENTE AMORFO, CON AGUA (5) O VAPOR DE AGUA A UNA TEMPERATURA DE UNOS 92JC COMO MINIMO, DURANTE UN TIEMPO DE UNOS TRES SEGUNDOS POR LO MENOS. EL FILAMENTO HUECO ES ALARGADO LENTAMENTE Y A TENSION BAJA EN DIRECCION LONGITUDINAL MIENTRAS ESTA EN CONTACTO CON EL AGUA. EL FILAMENTO YA DISTENDIDO PUEDE SER DESPUES ESTIRADO (10) DE FORMA CONVENCIONAL, ES DECIR, A GRAN VELOCIDAD Y BAJO UNA TENSION ALTA PARA ORIENTARLO.
