Abstract

Procedimientos para la fabricación de un hilo multicomponente consistente en al menos dos componentes poliméricos sintéticos, en cuya sección transversal uno de los componentes - el componente matriz- separa uno de otro al menos a dos, de preferencia al menos a tres segmentos del otro componente o de los otros componentes ¿ el componente segmento o los componentes segmentos- conservando estos segmentos su forma y posición en la sección transversal a lo largo del hilo, caracterizado porque el componente matriz es alimentado en una corriente de núcleo primeramente cerrado, coaxialmente a la abertura de hilatura de una boquilla de hilatura, y porque el componente segmento o los componentes segmentos es o son introducidos a presión desde una dirección radial en corrientes parciales, separadas espacialmente unas de otras, en el componente matriz, antes de su salida por la abertura de hilatura.
