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 substantially cylindrical, or tubular, garment structure can be provided using a three-dimensional or circular knitting machine, using a mold, or using an additive manufacturing process. A unit segment of the garment structure can include two waistband regions at opposite end faces of the cylindrical garment structure, and each of the waistband regions can correspond to a different one of two nested articles. Each of the two nested articles can be converted into a separate and distinct brief-style absorbent underwear assembly. In an example, a waistband region and body panel region of an absorbent underwear product can be formed using the same knitted material in a continuous, three-dimensional knitting process.

The present invention is intended to prevent cutting of the resilient and elastic members by a welding process. The foregoing issue is solved by passing a first sheet layer, a second sheet layer, and elongated resilient and elastic members continuously disposed in an MD direction between the two sheet layers, between a first roll with joint convex parts provided at circumferential intervals on an outer peripheral surface and a second roll opposed to the first roll, and pressurizing and heating the first sheet layer and the second sheet layer to form sheet joined sections by welding the first sheet layer and the second sheet layer in such a manner as to cross the resilient and elastic members and have MD-direction intervals therebetween, wherein circumferentially continuous grooves are formed on a pressurization surface of the second roll, passage sections of the resilient and elastic members are pressurized and heated in positions including the grooves of the second roll, and non-passage sections of the resilient and elastic members are pressurized and heated in positions not including the grooves of the second roll.

An absorbent article includes: a front waist portion extending along the lateral direction; a back waist portion extending along the lateral direction; and a crotch portion provided between the front waist portion and the back waist portion. A lateral end portion of the back waist portion on a one side and a lateral end portion of the front waist portion on the one side are joined by a first joining portion. The back waist portion has a fastening portion provided on another side in the lateral direction, and the fastening portion is capable of being fastened to the front waist portion when putting on the absorbent article. The front waist portion has a target region to which the fastening portion is to be fastened, and a lateral end of the target region on the one side is located on the one side relative to a lateral central position of the crotch portion.

An absorbent garment has a minimum crotch width less than 30% the front region width. The absorbent garment has an absorbent member minimum width less than 80 mm. The absorbent member minimum width is less than 53% the minimum crotch width and is less than 60% the absorbent member maximum width.

Articles of the present disclosure may have a tensile stress of the front proximal tummy zone higher than the tensile stress of any of the front waist zone, the front distal tummy zone, or the front leg zone, and a tensile stress of the back distal tummy zone higher than any of the tensile stress of the back waist zone, the back proximal tummy zone, or the back leg zone.

A stretchable/contractible sheet having an up-down direction and a left-right direction intersecting each other includes a first sheet; a second sheet; welded portions; and elastic members. Elastic members are arranged between the first sheet and the second sheet by welded portions and with a space in the up-down direction. The welded portions include a first welded portion; and a third welded portion. The welded portions further include a second welded portion; and a fourth welded portion. The first welded portion and the third welded portion have portions that overlap in the up-down direction. A length of a portion where the first welded portion and the third welded portion overlap in the up-down direction is larger than a length in the up-down direction between a lowermost end of the first welded portion and a lowermost end of the third welded portion.

Disclosed is a ring-like elastic belt comprising: a front belt and a back belt, each of the front belt and back belt comprising a tummy elastic array that comprises a major interval having a longitudinal dimension of at least about 10 mm; wherein the front belt and the back belt each have a Belt Tensile Strength of at least about 17.3 N/cm according to the measurements herein.

A disposable absorbent pant having a front belt portion and a rear belt portion is disclosed. The front and rear belt portions are joined at side seams and the rear belt portion has a greater length than the front belt portion. A lower edge of the rear belt portion forms at least in part edges of left and right leg openings to the rear of the side seams. The rear belt portion includes first and second layers of nonwoven web material sandwiching a plurality of laterally extending and laterally pre-strained elastic strands, disposed below the side seams. A first of the plurality of elastic strands differs from a second of the plurality of elastic strands by one or more of amount of pre-strain, tensile modulus, decitex, and combinations thereof.
