Abstract

LA INVENCION SE DIRIGE A UN PROCESO PARA LA PRODUCCION DE UN HILO MULTIFILAMENTO DE TELEFTALATO DE POLIETILENO, DIMENSIONALMENTE ESTABLE Y QUE CONSTA DE FILAMENTOS DE AL MENOS 2.5 "DENIER" POR FILAMENTO. EL PROCESO COMPRENDE LOS PASOS DE: A) LA EXTRUSION DE UN POLIMERO DE TELEFTALATO DE POLIETILENO FUNDIDO A TRAVES DE UNA BOQUILLA QUE TIENE UNA PLURALIDAD DE ORIFICIOS DE EXTRUSION PARA FORMAR FILAMENTOS; B) EL AVANCE DE LA HEBRA DE MULTIFILAMENTOS EXTRUDIDA PRIMERO A TRAVES DE UNA ZONA DE DEMORA Y POSTERIORMENTE A TRAVES DE UNA ZONA DE ENFRIAMIENTO SUBITO PARA SOLIDIFICAR LOS FILAMENTOS EN UNA FORMA CONTROLADA; C) LA EXTRACCION DE LA HEBRA MULTIFILAMENTOSA SOLIDIFICADA DE LA ZONA DE ENFRIAMIENTO BRUSCO A UNA VELOCIDAD DE ENROLLADO V; MEDIANTE LO CUAL LOS PASOS DESDE A) HASTA C) SE REALIZAN BAJO CONDICIONES ADECUADAS PARA FORMAR UNA HEBRA MULTIFILAMENTOSA PARCIALMENTE ORIENTADA QUE TENGA UNA BIRREFRIGENCIA (DELTAN SUB U) DE AL MENOS 0.020 Y EN DONDE DELTAN SUB U ES = R SUB FV ELEVADO 2.0IV ELEVADO 2.4 DONDE IV ES LA VISCOSIDAD INTRINSECA DE LA HEBRA EXTRAIDA Y ES AL MENOS 0.80 Y R SUB F ES AL MENOS 9.0 X 10 ELEVADO -3; Y D) LA EXTRACCION EN CALIENTE DE LA HEBRA MULTIFILAMENTOSA PARCIALMENTE ORIENTADA. EL PROCESO PERMITE LA PRODUCCION DE HEBRAS DE ALTA BIRREFRIGENCIA A VELOCIDADES INFERIORES IV''S INFERIORES QUE LAS PREVIAMENTE DEMOSTRADAS EN LOS PROCEDIMIENTOS ANTERIORES.
