The invention relates to a patterned spunbonded nonwoven fabric sheet comprising a plurality of spunbonded crimped fibers bonded together at a plurality of bonding points, wherein all fibers of the patterned spunbonded nonwoven fabric sheet are spunbonded crimped fibers and wherein the configuration of the fibers within the sheet is inhomogeneous and varies according to a preferably regular pattern. The invention further relates to a method for forming such patterned spunbonded nonwoven fabric sheet from a flat spunbonded nonwoven fabric sheet starting material. Still further, the invention relates to such flat spunbonded nonwoven fabric sheet starting material. L'invention concerne une feuille de tissu non-tissé filé-lié à motifs comprenant une pluralité de fibres frisées filées-liées liées ensemble au niveau d'une pluralité de points de liaison, toutes les fibres de la feuille de tissu non-tissé filé-lié à motifs étant des fibres frisées filées-liées et la configuration des fibres à l'intérieur de la feuille étant non homogène et variant selon un motif de préférence régulier. L'invention concerne en outre un procédé de formation d'une telle feuille de tissu non-tissé filé-lié à motifs à partir d'un matériau de départ de type feuille de tissu non tissé filé-lié plat. En outre, l'invention concerne un tel matériau de départ de type feuille de tissu non tissé filé-lié plat.
