Abstract

Procedimiento para preparar fibras a base de poliolefinas muy cristalinas de gran tenacidad, por extrusión de masa fundida, seguida por estiraje, caracterizado por el hecho de que los filamentos obtenidos por extrusión de la masa fundida, constituidos en esencia por poliolefinas y que salen de la hilera se mantinene a temperatura de 130º a 300ºC y luego se estiran y se someten a estabilización y a tratamientos de acabado.
