A fastening system includes an engaging component and a receiving component. The engaging component has a plurality of engaging elements capable of engaging the receiving component. The receiving component includes a nonwoven fabric having composite fibers, an embossed section, and a non-embossed section. The composite fibers are bonded together in the embossed sections. The composite fibers include a first propylene polymer and a second propylene polymer, wherein the first and second propylene polymers extend continually in a longitudinal direction and are arranged such that the second propylene polymer is associated with the first propylene polymer such that the composite fiber forms a crimp therein. The embossed sections have a plurality of zigzag unit patterns arranged in a machine direction which have a ratio of W1/W2 in the range of about 0.5 to about 2Ø

L'invention concerne un système de fixation comprenant un composant de couplage et un composant de réception. Le composant de couplage comporte plusieurs éléments de couplage permettant de coupler le composant de réception. Le composant de réception comprend un tissu non-tissé à fibres composites, une partie gaufrée et une partie non gaufrée. Les fibres composites sont liées entre elles dans des parties gaufrées. Elle contiennent un premier polymère propylène et un second polymère propylène, ces polymères s'étendant en continu dans une direction longitudinale et étant disposés de manière que le second polymère propylène soit associé au premier de sorte que les fibres composites forment un embuvage. Les parties gaufrées possèdent plusieurs motifs en zigzag disposés dans le sens machine à coefficient de W1/W2 compris entre environ 0,5 et environ 2.
