The present invention is directed towards yarns of covered high modulus filament materials and fabrics which are formed therefrom. The present invention is intended to provide a composite filamentary material which exhibits the advantages of high modulus materials while providing a means for compensating the diminished properties exhibited by such fibers in the direction normal to molecular chain orientation. The composite filament structure of the present invention is a high modulus filament material covered with bicomponent filaments. The composite filament structure has a first interior layer of high modulus filament material and a second exterior layer of bicomponent fibers, the second exterior layer of bicomponent fibers being covered around the first interior layer of high modulus material along its entire length. The entire surface area of the high modulus material should be covered.
La présente invention concerne des fils constitués de matériaux fil à haut module recouverts, ainsi que des tissus fabriqués à partir de ces matériaux. Elle a pour objet de fournir un matériau filiforme composite qui présente les avantages des matières à haut module, ainsi qu'un moyen de compenser la réduction des propriétés de telles fibres lorsque celles-ci sont dirigées dans le sens perpendiculaire à l'orientation de la chaîne moléculaire. La structure filiforme composite de la présente invention est un matériau filiforme à haut module, recouvert de filaments à deux composants. La structure filiforme composite comprend une première couche intérieure de matériau filiforme à haut module et une deuxième couche extérieure de fibres à deux composants recouvrant sur toute sa longueur la première couche intérieure de matériau filiforme. Toute la surface du matériau à haut module doit être recouverte.
