Abstract:
1. A receiving component of a fastener including a nonwoven web comprising a composite fiber having crimps, the nonwoven web comprising an embossed portion and a non-embossed portion on only one surface of the nonwoven web, the composite fibers in the embossed portion being bonded by thermal compression by an embossing roll, the composite fibers in the non-embossed portion being capable of engaging with a plurality of hooks of an engaging component, the embossed portion comprising an embossing pattern that comprises a plurality of zigzag unit patterns disposed in a machine direction, each zigzag unit pattern being spaced from each other, the zigzag unit patterns being continuous and parallel with a cross machine direction of the embossing roll, the zigzag unit patterns comprising a plurality of first diagonal lines and a plurality of second diagonal lines that are disposed alternately, the plurality of first diagonal lines being disposed parallel to each other and respective first diagonal lines being inclined to a first side at a same angle to the machine direction, the second diagonal lines being disposed parallel to each other and respective second diagonal lines being inclined to a second side at a same angle to the machine direction, first diagonal lines and second diagonal lines being continuous and connected alternately at an end portion or an adjacent portion to the end portion of the first diagonal lines and second diagonal lines, a triangle formed by adjacent three contact points of a first diagonal line and a second diagonal line adjacent to the first diagonal line of the zigzag unit pattern being overlapped by a part of another zigzag unit pattern that is adjacent to the triangle in the machine direction, where the three contact points are at a location where the first diagonal line and the adjacent second diagonal line connect and at other ends of the first diagonal line and the adjacent second diagonal line, and the triangle is formed when imaginary lines connect the three contact points to each other, the zigzag unit patterns having a ratio of W the composite fiber having crimps being a side-by-side composite fiber comprising a first propylene polymer and a second propylene polymer, wherein the first and second propylene polymers are arranged to occupy a first area and a second area of a cross section of the composite fiber, respectively, and extend continuously in a longitudinal direction, and each of the first and second propylene polymers forms at least a portion of peripheral surface continuously along the longitudinal direction of the composite fiber, and a melting point of the first propylene polymer measured by differential scanning calorimetry being higher than a melting point of the second propylene polymer by about 15° C. or more, and a weight ratio of the first propylene polymer to the second propylene polymer being from about 50/50 to about 5/95, wherein an area percentage of the embossed portion to a sum of the embossed portion and the non-embossed portion is in a range of about 20% to about 30%, and the nonwoven web is a spunbonded nonwoven web.
