Abstract

Procedimiento para el rizado tridimensional de bandas de filamentos múltiples, compuestos de un polímero termoplástico sintético de alto peso molecular, mediante maquinas de rizado por recalcado mecánico, caracterizado porque se rizan bandas cuyas secciones filamento individuales se encuentran simétricamente con respecto a dos ejes esencialmente perpendiculares entre si, estando los momentos de inercia superficial de las distintas secciones de filamento individual con respecto a estos ejes en una proporción de 3:1 hasta 7:1.
