Abstract
La presente invención se refiere a un procedimiento para fabricar hilos mediante hilado por fusión de tereftalato de polietileno (PETP), en cuyo procedimiento en una operación el PETP sólido se funde y el PETP fundido se extrae a tavés de orificios de hilar y se solidifica en un producto hilado que es estirado en un hilo, caracterizado porque se llenan los siguientes requisitos: a) el PETP sólido tiene una viscosidad relativa dentro de la escala de 1.8 a 2.1; b) antes de hilar el PETP se mezcla con 0.1 por ciento a 0.8 por ciento en peso de una bis centenimina; c) el PETP fundido se extrae de los orificios de la hilera a una velocidad dentro de la escala de 1500 a 4000 metros por minuto y d) el producto hilado formado se estira sin enrollamiento intermedio a una relación de estiraje de 1.5 a 4.0 con la condición de que la relación de estiraje de 1.5 a 4.0 con la condición de que la relación de estiraje no es de manera tal que la velocidad final del hilo sea mayor de 6000 metros por minuto.The present invention relates to a process for manufacturing yarns by melt spinning of polyethylene terephthalate (PETP), in which process in one operation the solid PETP is melted and the molten PETP is extracted through spinning holes and solidified in a spun product that is stretched on a thread, characterized in that the following requirements are met: a) solid PETP has a relative viscosity within the range of 1.8 to 2.1; b) before spinning the PETP is mixed with 0.1 percent to 0.8 percent by weight of a bis-centenimine; c) the melted PETP is extracted from the row holes at a speed within the scale of 1500 to 4000 meters per minute and d) the spun product formed is stretched without intermediate winding at a draw ratio of 1.5 to 4.0 with the condition that the draw ratio of 1.5 to 4.0 with the proviso that the draw ratio is not such that the final wire speed is greater than 6000 meters per minute.
