Beschreibung
Zusammenfassung:	The present invention provides nonwoven laminate materials with high overall uniformity of material properties, particularly tensile strength properties. The present invention also includes methods for forming the nonwoven laminate materials wherein the fiber extrusion and drawing apparati are oriented at a non-right angle with respect to the direction of web production or MD. L'invention concerne des matériaux stratifiés non tissés présentant une uniformité globale de propriétés de matériau élevée, en particulier, des propriétés de résistance à la traction. L'invention concerne également des procédés permettant de former lesdits matériaux stratifiés non tissés dans lesquels l'extrusion des fibres et les appareils d'étirage sont orientés selon un angle non droit par rapport au sens de production de la bande ou sens machine (MD).
