Abstract

Un procedimiento mejorado para fabricar un hilo con apariencia hilada, caracterizado por estirar un hilo de alimentación, comprendido dicho hilo de alimentación una pluralidad de filamentos continuos, teniendo cada uno de dicha pluralidad de filamentos un área en sección transversal que varía repetitivamente desde pequeños valores en regiones delgadas a grandes valores en regiones gruesas a lo largo de su longitud, siendo dichos valores grandes al menos el 25% mayores que dichos valores pequeños, efectuándose dicho estiraje a una relación de estiraje seleccionada para romper una pluralidad de dichos filamentos en dichas regiones delgadas.
