Abstract
PROCEDIMIENTO DE PRODUCCION DE HILO DE TEREFTALATO DE POLIETILENO ESTIRADO, HILO MULTIFILAMENTOSO ESTIRADO, CORDON PARA NEUMATICOS OBTENIDO DE DICHO HILO Y ARTICULOS QUE COMPRENDEN EL CORDON, TEREFTALATO DE POLIETILENO EN CONDICIONES DE ELEVADO ESFUERZO, SELECCIONANDO PARAMETROS PARA FORMAR UN HILO SIN ESTIRAR QUE ES UN HILADO PARCIALMENTE ORIENTADO CRISTALINO CON UNA CRISTALINIDAD DE 3-15% Y UNA ELEVACION DEL PUNTO DE FUSION DE 2-10GC. LUEGO SE ESTIRA EN CALIENTE A UNA RELACION TOTAL DE ENTRE 1,5/1 Y 2,5/1 CON LAS PROPIEDADES RESULTANTES: (A) MODULO TERMINAL DE AL MENOS 20 G/D, (B) ESTABILIDAD DIMENSIONAL DEFINIDA POR ASI4,5 + EL MENOR DE 13,5%, (C) TENACIDAD DE AL MENOS 7 GRAMOS POR DENIER, (D) ELEVACION DEL PUNTO DE FUSION DE 9-14GC, Y (E) FUNCION DE ORIENTACION AMORFA INFERIOR A 0,75. EL CORDON TRATADO RESULTANTE PARA NEUMATICOS PROPORCIONA UNA ELEVADA TENACIDAD EN COMBINACION CON UNA ESTABILIDAD DIMENSIONAL MEJORADA.
