Patent number: 9788701Abstract: According to a nonwoven fabric substrate (1) for wiping sheet of the invention, ridges (2) and grooves (3) are alternately formed at positions corresponding to each other on both surfaces (1a, 1b), and apertures (4) are formed in the grooves (3). Each of the ridges (2) and the grooves (3) extend parallel to one side of the nonwoven fabric substrate (1). Each of the grooves (3) alternately includes an aperture portion (3h) which has a plurality of the apertures (4), and a non-aperture portion (3n) which has no aperture (4) and is longer than a distance between the nearest end portions of the adjacent apertures (4) in the aperture portion (3h). An arrangement pattern of the aperture portion (3h) and the non-aperture portion (3n) provided in the groove (3a) is different from an arrangement pattern of the aperture portion (3h) and the non-aperture portion (3n) provided in an adjacent groove (3b).Type: GrantFiled: November 8, 2013Date of Patent: October 17, 2017Assignee: KAO CORPORATIONInventors: Taeko Hayase, Emiko Shirasaki, Minoru Wada

Patent number: 9782051Abstract: Provided is a nonwoven fabric substrate (1) in which ridges (2) and grooves (3) are alternately formed at positions corresponding to each other on each of both surfaces (1a, 1b), and apertures (4) penetrating the grooves (3) of both surfaces are formed. The ridges (2) and the grooves (3) extend parallel to each other. The ridges (2) and the grooves (3) extend in a direction intersecting with each of a pair of both sides (1c, 1d) extending in parallel of the nonwoven fabric substrate (1). In planar view, each of the grooves (3) alternately includes an aperture portion (3h) which has a plurality of the apertures (4), and a non-aperture portion which has no aperture (4) and is longer than a distance between the nearest end portions of the adjacent apertures (4) in the aperture portion (3h), and arrangement patterns of the aperture portion (3h) and the non-aperture portion (3n) provided in the adjacent grooves (3) are different from each other.Type: GrantFiled: November 8, 2013Date of Patent: October 10, 2017Assignee: KAO CORPORATIONInventors: Taeko Hayase, Emiko Shirasaki, Minoru Wada

Patent number: 6750165Abstract: A wet cleaning sheet 1 comprises an aqueous liquid-retaining layer 4 having an aqueous liquid-containing polymer and a chemical-containing layer 2 or 9 containing a chemical which causes the polymer to release the aqueous liquid. The aqueous liquid-retaining layer 4 and the chemical-containing layer 2 or 9 are formed and/or arranged in such a manner that they are kept out of substantial contact under no load applied but brought into contact with each other with a prescribed load applied whereby the aqueous liquid is gradually released from the polymer by the action of the chemical.Type: GrantFiled: June 5, 2002Date of Patent: June 15, 2004Assignee: Kao CorporationInventors: Shusuke Kakiuchi, Taeko Hayase

Publication number: 20030045197Abstract: A floor cleaning sheet (1) impregnated with an aqueous detergent is used as attached to a cleaning part (11) of a cleaning tool (10) having a handle (12) of stick form connected to the cleaning part (11). The surface layer of the floor cleaning sheet (1) which is to be brought into contact with a floor comprises nonwoven fabric formed by fiber entanglement of a fiber web and has a static friction resistance of 900 to 2500 cN against #1200-grit sandpaper.Type: ApplicationFiled: June 24, 2002Publication date: March 6, 2003Inventors: Shusuke Kakiuchi, Kenji Ishikawa, Taeko Hayase, Hiroyuki Akai
