Abstract

Se describe un proceso de hilado pro fusion y los filamentos huecos de nylon y los hilos fabricados por tal proceso el cual incluye extruir polímero de nylon fundido que tiene una viscosidad relativa (RV) de por lo menos aproximadamente 50 y un punto de fusion (TM) de aproximadamente 210 degree C a aproximadamente 210 degree C a aproximadamente 310 degree C desde un orificio capilar de hilera con segmentos de orificio multiples que proporcionan un área de extrusion total (EA) y un área vacía de extrusion (EVA) de manera que el contenido hueco de extrusion fraccional, definido por la proporcion, [EVA/EA] es de aproximadamente 0.6 a aproximadamente 0.95 y el grado de atenuacion de fusion, definido por la proporcion [EVA/(dpf)s, es desde aproximadamente 0.05 hasta aproximadamente 1.5, en la cual (dpf)s es el denier hilado por filamento, el (dpf)s se selecciona de manera que el denier por filamento a la elongacion al 25% (dpf)25 es aproximadamente 0.5 hasta aproximadamente 20 denier, la extraccion de corrientes de fusion multiples a partir de la hilera en una zona de enfriamiento bajo condiciones las cuales provocan autocoalescencia sustancialmente continua de las corrientes fundidas multiples de filamentos hilados tienen por lo menos un juego longitudinal y una proporcion de estirado residual (RDR) de menos de 2.75, y la estabilizacion de los filamentos huecos hilados proporcionan filamentos huecos con una proporcion de estirado residual (RDR) de aproximadamente 1.2 a aproximadamente 2.25.
