Abstract: A means which is to attach an absorbent article such as a sanitary napkin to an undergarment and disposed between a sanitary napkin and an inner surface of a crotch region of the undergarment. The means is formed by a first sheet and a second sheet overlying the first sheet. The first sheet 6 is elastically flexible and stretchable in its longitudinal direction and the second sheet has its longitudinally opposite end portions bonded to longitudinally opposite end portions of the first sheet and elastically stretchable at least in the longitudinal direction. The inner surface of the second sheet is formed so that the outer surface of the napkin may be fixed thereon.

Abstract: A topsheet for a disposable wearing article is formed with a plurality of fine openings each having an area of about 0.16-5 mm2 and a pant of the peripheral edge of each opening us protuberated upward from upper surface of the topsheet. The topsheet is thereby improved so that body fluids can be rapidly absorbed and stuffiness as well as eruption of the wearer's skin can be reliably avoided.

Abstract: In a fibrous web, press-welded line portions are formed, and press-welded dot portions are formed in portions other than the press-welded line portions. The formation of the press-welded line portions makes it possible to raise the surface of the fibrous web, to increase the bulkiness of the nonwoven fabric and to make the nonwoven fabric soft. Further, figures are drawn by the press-welded line portions, whereby the nonwoven fabric comes to have an excellent appearance in comparison to a conventional nonwoven fabric.

Abstract: A disposable body fluid absorbent wearing article includes a liquid-pervious topsheet including plastic film layer sections, liquid-pervious openings and a first fibrous layer bonded to the lower surface of the film layer sections. A second fibrous layer forming a liquid-absorbent core is contiguous to the lower surface of a first fibrous layer and a third fibrous layer is contiguous to the lower surface of the second fibrous layer. The wearing article is constructed so that its Klemm's water absorbency may progressively increase in the order of the first fibrous layer, the second fibrous layer and the third fibrous layer.

Abstract: In a fibrous web, press-welded line portions are formed, and press-welded dot portions are formed in portions other than the press-welded line portions. The formation of the press-welded line portions makes it possible to raise the surface of the fibrous web, to increase the bulkiness of the nonwoven fabric and to make the nonwoven fabric soft. Further, figures are drawn by the press-welded line portions, whereby the nonwoven fabric comes to have an excellent appearance in comparison to a conventional nonwoven fabric.

Abstract: A composite sheet includes a sheet-like fibrous assembly and a plurality of thermoplastic film layers. Each of the layers is formed on its upper surface with a plurality of grooves extending from one side edge to the other side edge of the layer.

Abstract: A flexible composite sheet includes a fibrous assembly and a plurality of narrow film strips bonded to upper surface of the fibrous assembly. The narrow strips are intermittently arranged so that the fibrous assembly may be exposed between each pair of the adjacent narrow strips. Sides defining each of the narrow strips are formed with tooth-like portions.

Abstract: A flexible sheet for disposable sanitary article includes a plurality of aperture-arrays each having a plurality of apertures, a plurality of plane regions arranged so that each pair of the adjacent plane regions have one of the aperture-arrays therebetween and a plurality of regions rising on the plane regions along their peripheral edges surrounding the respective apertures to form irregular undulations. The rising regions each defining on its both sides trough regions having a depth of at least 0.01 mm are distributed over the flexible sheet at a density of at least 500/cm2.

Abstract: A topsheet for body exudates absorbent article includes a hydrophilic nonwoven fibrous sheet and a plurality of thermoplastic synthetic resin filaments extending in one direction parallel to one another and continuously bonded to an upper surface of the nonwoven fibrous sheet so that a composite sheet of these sheet and filaments have crests and troughs alternately repeating longitudinally of the filaments and respectively extend transversely of the filaments. An apparatus and a method for manufcturing the topsheet are also disclosed, wherein a pair of mutually engageable embossing rolls are used for forming the crests and the troughs onto the coposite sheet.

Abstract: A female member of a mechanical fastener includes a fibrous layer and a plurality of strips. A plurality of ridges are intermittently shaped from a bottom side toward a top side of the fibrous layer. A plurality of strips are bonded to the bottom side of the fibrous layer so as to be spaced one from another and extend in parallel one to another in one direction so that the bottom side of the fibrous layer is spaced toward the top side of the fibrous layer from the respective strips along the respective ridges.
