Abstract

Un procedimiento de hilatura en fusión, para producir un hilo de poliamida de filamentos múltiples, que tiene una voluminosidad latente de un 18% por lo menos, caracterizado porque a) se extruye, a una velocidad de extrusión dada, a través de orificios de hilera no circulares, una poliamida formadora de fibra, que consiste esencialmente en unidades repetidas al azar de la fórmula **(Fórmula)** en las cuales la relación molar de unidades (i) a unidades (ii) se encuentra en el margen de aproximadamente 90:10 a aproximadamente 99:1, para formar una corriente fundida; (b) se enfría diferencialmente con rapidez dichas corrientes fundidas; y (c) se retiran dichos filamentos desde dicha zona de enfriamiento.
