Abstract: An absorbent article has a liquid-permeable top sheet of a white non-woven fabric, a liquid-impermeable back sheet opposing the top sheet, and an absorbent between the top sheet and the back sheet. A colored element is provided on the side of the top sheet that does not contact the skin, is visible through the top sheet, and is colored to a color other than white. The top sheet has protrusions and indentations in the thickness direction. The basic weight of the protrusions is greater than the basic weight of the indentations. The color difference between the Lab value of the color of the colored element visible through the protrusions of the top sheet and the Lab value of the color of the colored element visible through the indentations of the top sheet is 2.8 or more.

Abstract: An absorbent structure that includes a first region, a second region and a central region extending between the first and second regions, the first region and part of the central region are formed with a thick segment. The second region is formed with a thin segment having a thickness dimension smaller than that of the thick segment. Between the thick segment and the thin segment, a thickness-sloped segment having a thickness dimension gradually reduced from the side of the first region toward the second region and the thin segment and at least a region of the thickness-sloped segment being adjacent to the thin segment are debossed.

Abstract: The present invention aims to improve the tape fasteners provided on the diaper chassis so that the upper outside regions of the wearer's thighs should not be irritated by the edges of the tape fasteners. A lower edge of a first section in each tape fastener extends so that a space is defined between this lower edge and an imaginary extension of a lower edge of a second section in the tape fastener.

Abstract: A disposable wearing article improved so that a front waist region of a chassis can be reliably folded outwardly by relatively simple handling and, in such state, the article can be reliably fitted to the wearer's body. An article chassis is provided with an absorbent core extending across a crotch region into front and rear waist regions and the absorbent core is formed with a fold guiding zone extending across the front waist region in a direction of a transverse axis. A fastening system includes a first fastening system composed of first fastening elements provided on respective skin-contactable surfaces of a pair of fastening members extending outward in the direction of the transverse axis from lateral edges of the rear waist region and a second fastening system composed of the first fastening elements and a third fastening element formed on the skin-contactable surface of the front waist region.

Abstract: The present invention aims to provide an absorbent wearing article being capable of alleviating irritation to the wearer's skin as well as to be easily produced and a method for making the same. A liquid-absorbent chassis 4 is provided with a barrier cuff 5 including first and second barrier cuffs 5a, 5b each comprising an outermost edge 21, an innermost edge 24 and front and rear ends 22, 23 opposed to and spaced from each other in a longitudinal direction Y. The outermost edge 21 as well as the front and rear ends 22, 23 are joined to a topsheet 10 to define a fixed edge and the innermost edge 24 is not joined to the topsheet 10 to define a free edge adapted to be freely spaced from the liquid-absorbent chassis 4. Of the first and second barrier cuffs 5a, 5b, at least the fixed edge is formed by an inelastic, substantially non-extensible first sheet 25 while the free edge is formed by an elastically extensible second sheet 26.

Abstract: The present invention aims to provide a disposable diaper including leak barriers improved in its function to prevent loose passage from infiltrating thereinto and eventually leaching out therethrough. A disposable diaper (1) is provided with leak barriers (21) attached to opposite side edges of a crotch region (6) so that these leak barriers (21) may raise themselves on an inner sheet (3). The leak barriers (21) are formed of a nonwoven fabric made of thermoplastic synthetic fibers having a fineness in a range of 0.5 to 6 dtex and have a specific volume in a range of 9 to 13 cm3/g and a thickness in a range of 0.35 to 0.75 mm.

Abstract: The present invention aims to improve the tape fasteners provided on the diaper chassis so that the upper outside regions of the wearer's thighs should not be irritated by the edges of the tape fasteners. A lower edge 11a of a first section 11 in each tape fastener 10 extends so that a space S is defined between this lower edge 11a and an imaginary extension of a lower edge 12a of a second section 12 in the tape fastener 10.

Abstract: Multiple shape forming regions R1 each extending in a longitudinal direction of an absorbent article are formed in a top sheet in a cross direction. In each of the shape forming regions R1, a waveform including a top area T, a bottom area B, and a wall area between the top area T and the bottom area B is continuously formed in the longitudinal direction. The fiber density of the top sheet in the wall area W is set lower than the fiber density of the top sheet in the top area T or the bottom area B.

Abstract: An absorbent article such as a disposable diaper is provided with an indicator adapted to become visible as soon as bodily fluid is discharged. The indicator includes a composite nonwoven fabric composed of a hydrophilic melt blown nonwoven fabric layer and a hydrophilic spun bond nonwoven fabric layer on which a display element is depicted and laminated on one surface of the hydrophilic melt blown nonwoven fabric layer. A first surface of the composite nonwoven fabric facing an absorbent core of the diaper is held together with the display element and a second surface of the composite nonwoven fabric facing a backsheet of the diaper is held in close contact with the inner surface of the backsheet.

Abstract: In a disposable wearing article, and area of a rear waist region in which a core is present is divided into a first area and a second area. The second area is formed in its transversely middle zone with a through-hole extending through the core. A transverse fiexural stiffness of the core lying in the second area is lower than a transverse flexural stiffness of the core lying in the crotch region and the first area. Proximal portions of leak-barrier sheets and longitudinal ends of elastic members are in the first area. The first area lies above the crotch region in a thickness direction of the article and the second area forms a barrier and a pocket.

The display element is covered up by the composite nonwoven fabric in its dry state covers up and the display elements become visible from the outside of the backsheet through the nonwoven fabric as soon as the nonwoven fabric is wetted with bodily fluids.

Abstract: Here is disclosed a disposable wearing article in the article, an area of a rear waist region in which a core is present is divided into a first area and a second area. The second area is formed in its transversely middle zone with a through-hole extending through the core. A transverse flexural stiffness of the core lying in the second area is lower than a transverse flexural stiffness of the core lying in crotch region and the first area and proximal portions of leak-barrier sheets and longitudinal ends of elastic members are laid on the first area. The first area lies above the crotch region in a thickness direction of the article and the second area forms a barrier and a pocket.
