A waist portion W has a first portion P1 and a second portion P2 each including a waist elastic member. The first portion P1 includes an over sheet layer folded back at an edge of a waist opening WO extending to an inside of a waist inner sheet layer. The over sheet layer is formed of a sheet material having a portion folded back at an edge of the waist opening WO from a position outside the waist elastic member in the second portion P2 and extending to a position inside the waist elastic member in the second portion P2. In the first portion P1, the waist elastic member is not fixed to the sheet material. In the second portion P2, the waist elastic member is fixed to the sheet material, and the sheet material is contracted in a width direction WD together with the waist elastic member.

Methods of making laminates for absorbent articles

A method of making a laminate for an absorbent article is provided. The laminate comprises elastic elements disposed at least partially intermediate two substrates. The first substrate has a primary fiber bond pattern formed therein and comprising a plurality of primary fiber bonds. The method comprises forming densified regions in the first substrate. A perimeter of each of the densified regions is larger than a perimeter of each of the primary fiber bonds. The densified regions together form a pattern of densified regions in the first substrate. The method comprises adhesively attaching the elastic elements to the first substrate, joining the second substrate to the first substrate or to some of the elastic elements, and forming a plurality of rugosities in the first substrate by allowing the elastic elements to at least partially contract. The frequency and amplitude ranges of the rugosities result from the pattern of the densified regions.

Wearable article having elastic belt

An article with the entirety of the length of the belt side edge of the front belt seamed with a certain length of the belt side edge of the back belt to define a seam length LS. The front and back belts may each be divided into 4 zones extending in the transverse direction and defined by its location from the distal edge to the proximal edge relative to the percentage of the seam length LS where: 0-25% is the waist zone, 25-50% is the distal tummy zone, 50-85% is the proximal tummy zone, and 85-100% is the leg zone. The tensile stress of the front leg zone may be no more than 50% of the tensile stress of the front proximal tummy zone, and the tensile stress of the back leg zone may be no more than 100% of the tensile stress of the back proximal tummy zone.

PANT-TYPE ABSORBENT ARTICLE WITH WAIST GUARD

Disclosed is a pant type absorbent article having a waist guard on the back elastic belt, wherein the waist guard comprises a waist guard elastic portion. The absorbent article has a Blowout Percent Leakage of less than 1% when subjected to the Blowout Method herein.

Absorbent article with waist gasketing element and leg cuffs

A disposable absorbent article may include a chassis that includes a topsheet, a backsheet, and an absorbent core disposed between the topsheet and the backsheet; and a leg gasketing system and a waist gasketing element. The leg gasketing system may include an inner cuff and an outer cuff; the inner cuff may include an inner cuff folded edge and an inner cuff material edge and the outer cuff may include an outer cuff folded edge and an outer cuff material edge such that the web of material is folded laterally inward to form the outer cuff folded edge and folded laterally outward to form the inner cuff folded edge. The leg gasketing system may also include a pocket. When tested by the Blowout Method Test as described herein, the disposable absorbent article has a Blowout Percent Leakage of less than about 9.0%.

Absorbent article having a folded waist

An article including a front region, a back region, and a chassis. The chassis may include an absorbent core having a front end edge and a back end edge. The front region and the back region may extend laterally outward beyond side edges of the chassis. The front region and the back region may abut to form a first seam and a second seam. At least one of the front region and the back region may include an elastic member. A first outer nonwoven layer of the front region and a second outer nonwoven layer of the back region may be folded to form an upper edge in the front and back regions such that a distal end of each of the first and second outer nonwoven layer may be disposed between the upper edge and the front and back end edges of the absorbent core, respectively.
