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 2.0.

What is claimed is: 1. A fastening system comprising: an engaging component comprising a plurality of engaging elements; a receiving component, wherein the engaging component is capable of engaging the receiving member, the receiving component comprising: a nonwoven fabric comprising: composite fibers having a first propylene polymer and a second propylene polymer, wherein the first and second propylene polymers extend continually in a longitudinal direction and the second propylene type polymer is associated with the first propylene type polymer such that the composite fiber forms a crimp therein; embossed sections having a plurality of zigzag unit patterns arranged in a machine direction with predetermined spacings, the zigzag unit patterns continually extending substantially parallel with a cross direction of the embossing roll, wherein the zigzag unit patterns each comprise a continual zigzag pattern in which a plurality of first diagonal lines and a plurality of second diagonal lines are arranged alternately and are connected together adjacent to end parts of the diagonal lines, the first diagonal lines being arranged at a first angle with respect to the cross direction and being inclined to one side at about the same first angle relative to the machine direction, the second diagonal lines being arranged at a second angle with respect to the cross direction and being inclined to the other side at about the same second angle relative to the machine direction, wherein the first diagonal lines and the second diagonal lines in the zigzag unit pattern form triangles comprising three adjacent contact points of diagonal lines, the triangles including part of the zigzag unit pattern extending in the machine direction adjacent thereto; and nonembossed sections, wherein the composite fibers are bonded together in the embossed sections, and wherein the unit pattern has a ratio of W1/W2 in the range of about 0.5 to about 2.0. 2. The fastening system of claim 1, wherein the predetermined spacing W3 is between about 2 mm to about 5 mm and W1 is between about 5 mm to about 20 mm. 3. The fastening system of claim 1, wherein at least one of the first diagonal lines extends beyond a contact point. 4. The fastening system of claim 1, wherein at least one of the second diagonal lines extends beyond a contact point. 5. The fastening system of claim 1, wherein the embossed section further comprises dot patterns which are disposed between two adjacent unit patterns and in which the composite fibers are bonded together by thermocompression bonding with an embossing roll. 6. The fastening system of claim 1, wherein the first and second propylene polymers have a ratio of melt flow rate (MFR, 230° C., 2.16 kg load) measured in accordance with ASTM D 1238 in the range of 0.8 to 1.2 (second propylene polymer/first propylene polymer). 7. The fastening system of claim 1, wherein the first and second propylene polymers are each a propylene homopolymer or a propylene/ethylene random copolymer having an ethylene unit content in the range of 0 to 10 mol % and a melt flow rate (MFR, 230° C., 2.16 kg load) in the range of 20 to 200 g/10 min as measured in accordance with ASTM D 1238. 8. The fastening system of claim 1, wherein the nonwoven fabric comprises a laminate wherein the nonwoven fabric comprising the crimped composite fiber is disposed as an outermost layer of the laminate, and wherein at least one layer is laminated on a back surface of the nonwoven fabric. 9. The fastening system of claim 7, wherein the nonwoven fabric comprises a laminate wherein the nonwoven fabric is joined to a second nonwoven fabric comprising a propylene polymer fiber in a face-to-face orientation. 10. A disposable article comprising: an outer-facing surface, a wearer-facing surface, and a fastening system disposed on the outer-facing surface or the wearer-facing surface of the article, the fastening system comprising: an engaging component comprising a plurality of engaging elements; a receiving component, wherein the engaging component is capable of engaging the receiving member, the receiving component comprising: a nonwoven fabric comprising: composite fibers having a first propylene polymer and a second propylene polymer, wherein the first and second propylene polymers extend continually in a longitudinal direction and the second propylene type polymer is associated with the first propylene type polymer such that the composite fiber forms a crimp therein; embossed sections having a plurality of zigzag unit patterns arranged in a machine direction with predetermined spacings, the zigzag unit patterns continually extending substantially parallel with a cross direction of the embossing roll, wherein the zigzag unit patterns each comprise a continual zigzag pattern in which a plurality of first diagonal lines and a plurality of second diagonal lines are arranged alternately and are connected together adjacent to end parts of the diagonal lines, the first diagonal lines being arranged at a first angle with respect to the cross direction and being inclined to one side at about the same first angle relative to the machine direction, the second diagonal lines being arranged at a second angle with respect to the cross direction and being inclined to the other side at about the same second angle relative to the machine direction, wherein the first diagonal lines and the second diagonal lines in the zigzag unit pattern form triangles comprising three adjacent contact points of diagonal lines, the triangles including part of the zigzag unit pattern extending in the machine direction adjacent thereto; and nonembossed sections, wherein the composite fibers are bonded together in the embossed sections, and wherein the unit pattern has a ratio of W1/W2 in the range of about 0.5 to about 2.0. 11. The disposable article of claim 10, wherein the article is selected from group consisting of: an absorbent article, a diaper, a pant, an adult incontinence article, a feminine hygiene article, a body wrap, a bib, and a consumer good. 12. The disposable article of claim 11, wherein the article is a diaper, and wherein the receiving component is joined to an outer-facing surface of the diaper. 13. The disposable article of claim 10, wherein the predetermined spacing W3 is between about 2 mm to about 5 mm and W1 is between about 5 mm to about 20 mm. 14.
