Disclosed is a pant type absorbent article having a back elastic belt comprising a waist guard portion extending towards the crotch region from a closed base line towards an open edge, wherein the waist guard portion is formed by a first inner waist fold extending from a second inner waist fold, the second inner waist fold extending from the inner sheet, and a first elastic member bonded between the first inner waist fold and the second inner waist fold, wherein the waist guard portion is partially bonded to the remainder of the elastic belt from which the first and second inner waist folds extend to define a pocket.

A pull-on diaper for younger baby has a transverse direction and a longitudinal direction, front and waist regions, a crotch region, and rear waist regions and leg cuffs extending along respective laterals of the crotch region. Each of front and rear waist panels is sectionalized into a first elastically contractible region and a second elastically contractible region wherein a dimensional ratio in the longitudinal direction between the first elastically contractible region and the second elastically contractible region is in a range of 1:1.6 to 1:2.2 and an elongation ratio of waist elastics attached to the first elastically contractible region is lower than an elongation ratio of the waist elastics attached to the second elastically contractible region and the elongation ratio of the waist elastics attached to the second elastically contractible region is lower than an elongation ratio of leg cuff elastics.

Disclosed is a pant type absorbent article having a waist guard portion on the back elastic belt, wherein the waist guard portion has a specific location in view of the location from the distal edge to the proximal edge relative to the percentage of the seam length LS, the waist guard portion comprising a waist guard elastic portion having a longitudinal dimension of no greater than about 40 mm, wherein the remainder of the elastic belt superposing the waist guard elastic portion is defined a correlated portion, wherein the tensile stress of the waist guard elastic portion is higher than that of the correlated portion.

Disclosed is a pant type absorbent article having a waist guard portion on the front and/or back elastic belt, wherein the waist guard portion has a specific location in view of the location from the distal edge to the proximal edge relative to the percentage of the seam length LS, the waist guard portion comprising a waist guard elastic portion having a longitudinal dimension of no greater than about 40mm, wherein the remainder of the elastic belt superposing the waist guard elastic portion is defined a correlated portion, wherein the tensile stress of the waist guard elastic portion is higher than that of the correlated portion.

A composite laminate is provided with improved appearance aesthetics and functionality for use in disposable diaper and hygiene products, providing particularly low elongation dependency of unload power, and a soft feel. The composite laminate body has a plurality of elastic fibers arranged in parallel in one direction, interposed between two sheets of cloth; and resin bonding the elastic fibers and the two sheets of cloth, provided in a plurality of strands arranged to be parallel in one direction that intersects with the elastic fibers; wherein the two sheets of cloth and the elastic fibers are separated between locations where adjacent resin strands and elastic fibers intersect in the longitudinal direction of the elastic fibers.

An absorbent article such as a baby diaper comprising a three-dimensional laminate 30 having a first layer 1 intermittently bonded to a second layer 2 by a heterophase polymer. The topsheet comprises three-dimensional protrusions 9 in the first layer 1 which are not bonded to the second layer 2. The heterophase polymer has an enthalpy of fusion of at least 10 J/g. The laminate may be used on the wearer-facing side of the article as topsheet 24 and/or on the garment-facing side as part of the backsheet 26. The first layer may comprise natural fibers.

An absorbent article includes a stretchable sheet that is a laminate of a non-stretchable first sheet layer, a non-stretchable second sheet layer, and an elastic film disposed between the first and second sheet layers, and the elastic film is stretchable at least in the front-back direction. The first sheet layer is bonded to the second sheet layer at a large number of joints directly or through the elastic film and the joints are arrayed at intervals. The stretchable sheet is contracted by a contraction force of the elastic film and can be stretched by an external force applied in the front-back direction. The leg portion is also contracted by a contraction force of the elastic film and can be stretched by an external force applied in the width direction. The leg portions and adjoined regions have different joint area rates and thereby have different stretching stresses.

An absorbent article includes a liquid pervious topsheet, a backsheet at least peripherally joined to the topsheet, and an absorbent core disposed between said topsheet and said backsheet. The absorbent article further includes an integrated nonwoven fluid management layer having a basis weight between about 40 gsm and about 65 gsm; and an Urine Standard Rewet Value of 10 mg or less.

A fluid management layer having an integrated, carded, nonwoven is described. The fluid management layer has a basis weight of between about 40 grams per square meter (gsm) and about 75 gsm; a plurality of absorbent fibers, a plurality of stiffening fibers and a plurality of resilient fibers; wherein the fluid management layer exhibits a total compression of greater than 0.40 mm and has a total recovery of at least 0.35 mm, and wherein the fluid management layer has a density of less than or equal to 0.08 g/cc.
