Publication number: 20100191207Abstract: The present invention aims to provide liquid-pervious nonwoven fabric allowing body fluids to be spot-permeated. A nonwoven fabric includes core-sheath type composite fiber of 100 to 30% by weight wherein a core component comprises high fusion point resin and a sheath component comprises a low fusion point resin. In a cut surface of the nonwoven fabric extending in parallel to a first direction, the composite fibers extend in the first direction with repetitive curvatures in a thickness direction of the nonwoven fabric. In a cut surface of the nonwoven fabric extending in a second direction, the composite fibers 2 extend in the thickness direction TD at an average fiber angle of 75° or less. The individual composite fibers intersect one another and fused together at respective intersection points by fusion of the low fusion point resin forming the sheath component.Type: ApplicationFiled: March 18, 2008Publication date: July 29, 2010Applicant: UNI-CHARM CORPORATIONInventors: Toru Oba, Satoshi Mizutani, Hideyuki Ishikawa

Patent number: 7449014Abstract: A disposable wearing article is provided with leg elastic elements. The leg elastic elements include first leg elastic elements extending from transversely opposite margins of a front waist region to a front half of a crotch region and second leg elastic elements extending from transversely opposite margins of a rear waist region toward a rear half of the crotch region across a rear half of the crotch region. The first elastic elements extend generally in a transverse direction while the second elastic elements extend in a direction orthogonal to a transverse center line in such a manner that these elastic elements get nearer to a longitudinal center line as these elastic element extend from the rear waist region toward the crotch region.Type: GrantFiled: February 28, 2006Date of Patent: November 11, 2008Assignee: Uni-Charm CorporationInventors: Toru Oba, Takanori Matsuo
