An absorbent article includes a chassis. The chassis includes a topsheet, a backsheet, and an absorbent core disposed between the topsheet and the backsheet, and at least one elastically elongatable panel joined to the chassis. The elastically elongatable panel includes a stretch laminate having layers that are joined by ultrasonic bonding. The stretch laminate has at least one cover layer and an elastomeric film attached to the cover layer. The elastomeric film has two surfaces and a skin on at least one of the surfaces. The stretch laminate includes at least one anchoring zone and at least one stretch zone. The stretch laminate may include activation stripes and/or a plurality of wrinkles.

A stretch laminate is disclosed. The stretch laminate may include a layer of nonwoven material that includes an accumulation of filaments and has an inner surface and an outer surface, the outer surface having an ordered arrangement of zones, each zone having an attenuated region adjacent to a build-up region wherein the attenuated region has a first basis weight and the build-up region has a second basis weight greater than the first basis weight, the difference in basis weights corresponding to disposition of the filaments according to the ordered arrangement. The stretch laminate may include a plurality of elastic strands space apart from each other in a crotch-stretch direction. In some examples the elastic strands may have an Average Strand Spacing no greater than 3 mm and/or an Average Decitex no greater than 300, and/or an Average Pre-Strain no greater than 250 percent.

A disposable wearing article includes: a waist portion having an outer side portion exposed on an external surface and an inner side portion overlapped with an inner side of the outer side portion; an adjacent portion adjacent to the waist portion; an outer side stretchable region extending over the outer side portion and the waist adjacent portion; and an inner side stretchable region provided in the inner side portion, wherein the outer side portion and the inner side portion are joined with each other in a stripe pattern formed by disposing, alternately and repeatedly in the width direction, inner/outer bonded portions continuous in a front-back direction and inner/outer non-bonded portions continuous in the front-back direction, and a natural length in the width direction of the outer side portion is 1.1 to 1.8 times a natural length in the width direction of the inner side portion.

In order to prevent degradation of appearance, prevent a decrease in flexibility, and improve non-elasticity in a non-stretchable region in an elastic film stretchable structure, the invention is characterized by having an elastic film stretchable structure (20X) formed by stacking an elastic film (30) between a first sheet layer (20A) and a second sheet layer (20B), wherein a region having the elastic film stretchable structure (20X) includes a non-stretchable region (70) and a stretchable region (80) provided at least at one side of the non-stretchable region (70) in a stretching and contracting direction, the stretchable region (80) being stretchable in the stretching and contracting direction, the first sheet layer (20A) and the second sheet layer (20B) are joined via through holes (31) penetrating the elastic film (30) at the large number of sheet bond portions (40) arranged at intervals, and the non-stretchable region (70) does not have a section in which the elastic film (30) linearly continues along the stretching and contracting direction, due to presence of the through holes (31), even though the elastic film (30) continues in the stretching and contracting direction.

The present disclosure relates to one or a combination of an absorbent article's chassis, inner leg cuffs, outer leg cuffs, ear panels, side panels, waistbands, and belts that may comprise one or more pluralities of tightly spaced (less than 4 mm, less than 3 mm, less than 2 mm, and less than 1 mm) and/or very fine (less than 300, less than 200, less than 100 dtex) and/or low strain (less than 300%, less than 200%, less than 100%) elastics to deliver low pressure less than 1 psi (according to the conditions defined by the Pressure-Under-Strand method below) under the elastics, while providing adequate modulus of (between about 2 gf/mm and 15 gf/mm) to make the article easy to apply and to comfortably maintain the article in place on the wearer, even with a loaded core (holding at least 50 mls of liquid), to provide for the advantages described above.

The present disclosure relates to methods for making elastomeric laminates that may be used as components of absorbent articles. The elastomeric laminates may include a first substrate, a second substrate, and an elastic material located between the first and second substrates. During assembly of an elastomeric laminate, a beam is rotated to unwind the elastic strands from the beam, wherein the strands may include a spin finish. First bonds are applied to bond discrete lengths of the stretched elastic strands with and between the first substrate and the second substrate, wherein the discrete first bonds are arranged intermittently along the machine direction. In addition, second bonds are applied between consecutive first bonds to bond the first and second substrates directly to each other, wherein the second bonds extend in the machine direction and may be separated from each other in a cross direction by at least one elastic strand.

The present disclosure relates to methods for making elastomeric laminates that may be used as components of absorbent articles. In particular, discrete mechanical bonds are applied to a first substrate and a second substrate to secure elastic strands therebetween, wherein the discrete bonds are arranged intermittently along the machine direction. During the bonding process, heat and pressure are applied to the first substrate and the second substrate such that malleable materials of the first and second substrates deform to completely surround an outer perimeter of a discrete length of the stretched elastic strand. After removing the heat and pressure from the first and second substrates, the malleable materials harden to define a bond conforming with a cross sectional shape defined by the outer perimeter of the stretched elastic strand.

An absorbent article is disclosed. The absorbent article includes a core and a chassis. One or more discrete bonding zones bond the core to the chassis, and one or more unbonded zones of the core are not bonded to the chassis, forming a floating core. The core is not elastically coupled with the chassis. A method of making the absorbent article may include selectively bonding the chassis to the core at discrete bonding zones.

An absorbent article includes a first waist region, a second waist region, and a crotch region disposed between the first and second waist regions. The article also includes a chassis having a topsheet, a backsheet, and an absorbent core disposed between the topsheet and backsheet; and an ear joined to the chassis. The ear includes a laminate formed from a nonwoven and an elastomeric material sandwiched between said first and second nonwovens. The laminate further includes a plurality of ultrasonic bonds.
