The present invention is intended to improve the liquid diffusibility and fit of an absorber having a first slit extending in a front-back direction and second slits continuing laterally from the first slit to the side edges. The foregoing issue is solved by providing one first slit extending in the front-back direction in a width-direction intermediate portion of an absorber, providing second slits continuing from each of front end side and back end side of the first slit toward width-direction both sides to the side edges, and providing second slit elastic members to cross in the direction of continuance of the second slits and exert a contraction force in the direction of closing of the second slits.

A diaper has vertical and lateral directions, and a skin facing surface and a non-skin facing surface on an opposite side thereof, includes a front waist region, a rear waist region, a crotch region positioned between the front and rear waist regions, and includes a pair of leg openings, and a waist opening defined by side edges of the front and rear waist regions. At least one of the front and rear waist regions includes a pair of tape fasteners fixed to the non-skin facing surface of the side edges. At least one of the front and rear waist regions includes a pocket openable toward the crotch region, on the skin facing surface. An upper end of a fixing part of the tape fastener is positioned at a lower side of a closing edge (folding part) positioned on the waist opening side of the pocket in the vertical direction.

A tape-type disposable diaper wherein lower edges of wing parts of a ventral part have a first part on a base edge side and a second part on a tip end side, which are wavy portions having inward recessed valleys. In the wavy portion of the first part, the obtuse side intersection angle .sub.1 between a tangent contacting both of adjacent valleys and a front-back direction is 160 to 175 degrees. In the wavy portion of the second part, an obtuse side intersection angle .sub.2 between a tangent contacting both of the adjacent valleys and the front-back direction is 120 to 150 degrees. The first part in the front-back direction is 0.15 to 0.30 times the dimension of the crotch portion in the front-back direction, and the second part in the front-back direction is 0.10 to 0.25 times the dimension of the crotch portion in the front-back direction.

A wetness indicating composition can include a mixing solvent including water and a water-miscible volatile organic solvent. The wetness indicating composition can also include an amphiphilic polydiacetylene and a hydrophobic binder. In some embodiments, the wetness indicating composition can be applied to a substrate and serve as a wetness indicator for an absorbent article.

Absorbent articles with substantially cellulose-free cores with zeolites.

A diaper is configured to prevent a projecting section from being folded between the diaper and the skin. Lower edges of a wing part have a wavy portion having a plurality of outwardly bulging peaks. A side elastic member is on the width direction center side of the wing part in the side flap portion. A flat gather is contracted in the front-back direction by the side elastic member. An overlapping range is provided where a front-back direction range in which contraction force of the side elastic member acts and part of a front-back direction range of the wavy portion overlap, the maximum elongation of the flat gather is 150 to 350%, the width direction interval between the side elastic member and the wavy portion in the overlapping range is 15 to 50 mm at the maximum and 5 to 20 mm at the minimum.

An absorbent article can include a chassis including an absorbent body. The chassis can include a body facing surface. The absorbent article can also include a pair of body exudate containment flaps attached to the body facing surface of the chassis. The containment flaps can include a first portion located in the front portion of the absorbent article and chassis, and a second portion located in the rear portion of the absorbent article and chassis. The second portion of the containment flaps can have one or more properties that are different than one or more properties of the first portion of the containment flaps to reduce the lateral flow of body exudates out the sides of the absorbent article.

A disposable absorbent product includes a double-network polymer element including a cross-linked, covalently-bonded polymer and a reversible, partially ionicly-bonded polymer, wherein the element has a moisture level less than or equal to 15 percent of the total weight of the element, wherein the element comprises a latent retractive force, and wherein the element is configured to release the retractive force to achieve a dimensional change in the disposable absorbent product with exposure of the element to an aqueous liquid. Manufacturing a disposable absorbent product includes producing a double-network hydrogel; elongating by force and dehydrating while still elongated the double-network hydrogel, wherein elongating and dehydrating captures a latent retractive force in the element; and positioning the element in a disposable absorbent product such that a dimensional change in the disposable absorbent product is achieved with exposure of the element to an aqueous liquid.

A disposable diaper having a first sheet of viscose fiber material disposed against a child's skin, an acquisition and diffusion layer (ADL) interposed over top of the first sheet of viscose fiber, a coating layer of tissue fiber interposed over top of the ADL layer, an absorbency core layer interposed over top of the coating layer, a permeable layer of polymer film interposed over top of the absorbency core layer, and a second sheet of viscose fiber material overlaid over top of the permeable polymer film layer, the second sheet functioning as the exterior sheet of the disposable diaper.

A low bulk, high capacity disposable absorbent pant is disclosed. The pant may have a variety of combinations of features that contribute to imparting the pant with a more close-fitting, discreet appearance, particularly under outer clothing, more resembling that of an ordinary undergarment. The features may include an arrangement of relatively closely-spaced elastomeric strands in a belt structure; elastomeric strands in the belt structure having active portions that traverse forward and rearward portions of an absorbent pad assembly; an arrangement of elastomeric strands in the belt structure below the side seams; an arrangement of longitudinal elastic strands in the absorbent pad assembly that are closer to the longitudinal axis of the pant than to the side seams; and/or an absorbent core structure having portions that are tapered and/or channeled.
