ABSTRACT A non-woven fabric is characterized by including a filament layer in which one or more continuous filaments composed of a polymeric material are spirally collected substantially along a shape obtained by offsetting an ellipse having an elongated major axis in a plane. This non-woven fabric can be obtained by spinning a filament composed of a polymeric material, vibrating the filament, amplifying vibration of the filament, and collecting the filament into an elliptic shape having an elongated major axis so that the filament is arranged in a direction of the major axis.

Tissu non tissé caractérisé en ce qu'il comprend une couche de filaments dans laquelle de nombreux filaments formés sur un matériau polymère sont agencés en spirale, telles de nombreuses ellipses étroites disposées sur un plan l'une à côté de l'autre. On produit ce tissu en filant un matériau polymère, en faisant vibrer les filaments, en amplifiant la vibration et en disposant les filaments de manière à former un ensemble d'ellipses étroites essentiellement dans le sens de l'axe principal de l'ellipse.
