Abstract

PROCEDIMIENTO DE EXTRUSION DE UN POLIESTER LINEAL FUNDIDO. SE FUNDE EL POLIESTER SINTETICO A TRAVES DE UN ORIFICIO DE HILERA PARA FORMAR UN FILAMENTO QUE TIENE AL MENOS UNA ALETA QUE SE EXTIENDE A PARTIR DE UNA PARTE DE VASTAGO. SE ENFRIA EL FILAMENTO DIRIGIENDO UNA CIRCULACION CONTROLADA DE GAS DE REFRIGERACION A TRAVES DEL FILAMENTO CERCA DEL ORIFICIO. SE DESPLAZA EL FILAMENTO A TRAVES DE LA ZONA DE REFRIGERACION A UNA GRAN VALOCIDAD, ESTIRANDOLO POSTERIORMENTE DE UNA A CUATRO VECES SU LONGITUD ORIGINAL EN CONDICIONES DE CONSERVACION DE SU ESTADO AMORFO. SE ENCOGE EL FILAMENTO ESTIRADO EN 15-75% PARA PRODUCIR UN FILAMENTO ONDULADO.
