NONWOVEN, SHEET FOR ABSORBENT ARTICLE, AND ABSORBENT ARTICLE USING THE SAME

摘要

The present invention relates to a nonwoven comprising: a first fiber layer comprising a first core/sheath composite fiber having three-dimensional crimp, which is composed of a sheath component comprising linear low density polyethylene, and a core component comprising thermoplastic resin having a high melting point, and the center of gravity of the core component being offset from the center of gravity of the fiber; a second fiber layer comprising a second core/sheath composite fiber having three-dimensional crimp, which is composed of a sheath component comprising high density polyethylene, a core component comprising thermoplastic resin having a high melting point, the center of gravity of the core component being offset from the center of gravity of the fiber; wherein at least a portion of the first and the second core/sheath composite fibers is thermal bonded via the sheath components of the first and the second core/sheath composite fibers

1. A sheet for an absorbent article comprising a nonwoven comprising
a first fiber layer comprising a first core/sheath composite fiber having three-dimensional crimp, wherein a sheath component of the first core/sheath composite fiber comprises linear low density polyethylene, a core component of the first core/sheath composite fiber comprises thermoplastic resin having a melting point of at least about 20° C. higher than a melting point of the linear low density polyethylene, and the center of gravity of the core component is offset from the center of gravity of the fiber; a second fiber layer comprising a second core/sheath composite fiber having three-dimensional crimp, wherein a sheath component of the second core/sheath composite fiber comprises high density polyethylene, a core component of the second core/sheath composite fiber comprises thermoplastic resin having a melting point of at least about 20° C. higher than a melting point of the high density polyethylene, and the center of gravity of the core component is offset from the center of gravity of the fiber; wherein at least a portion of the first and the second core/sheath composite fibers is thermally bonded via the sheath components of the first and the second core/sheath composite fibers.
