The present disclosure relates to absorbent articles having a waist gasketing element, with the gasketing element having an adhesive zone and one or more adhesive-free zones. At least a portion of the waist gasketing element is adhesively attached to a chassis of the absorbent article. Additionally, a portion of the waist gasketing element is mechanically attached to a portion of the absorbent article. The bio-based content of the absorbent article is from about 5% to about 100% using ASTM D6866-10, method B.

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. Aspects of the methods for assembling elastomeric laminates may utilize elastic strands supplied from beams that may be joined with first and second substrates, and may be configured to carry out various types of operations, such as bonding and splicing operations.

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.

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 an 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 partially bonded to the remainder of the back elastic belt to define a pocket.

Ultrasonic welding is performed by passing a first sheet layer, a second sheet layer, and an elastic film interposed therebetween in a stretched state in a machine direction between an anvil roll having a large number of protrusions and an ultrasonic horn. The anvil roll includes a region having the protrusions and in the region. A site, in which welding is performed by one ultrasonic horn, has a portion in which an area rate of the protrusions changes in a roll circumferential direction and a roll length direction. A difference between a maximum value and a minimum value in a change of the area rate of the protrusions in the roll circumferential direction is 4.5% or less, and a difference between a maximum value and a minimum value in a change of the area rate of the protrusions in the roll length direction is 1.5% or less.

The present disclosure relates to assembling elastic laminates that may be used to make absorbent article components. Methods herein may include an anvil adapted to rotate about an axis of rotation, wherein first and second spreader mechanisms adjacent the anvil roll are axially and angularly displaced from each other with respect to the axis of rotation. During the assembly process, a substrate may be advanced in a machine direction onto the rotating anvil. The first spreader mechanism stretches a first elastic material in the cross direction, and the second spreader mechanism stretches a second elastic material in the cross direction. The stretched first and second elastic materials advance from the spreader mechanisms and onto the substrate on the anvil roll. The combined and elastic materials may then be ultrasonically bonded together on the anvil to form at least one elastic laminate.

Disclosed is an array 1 of wearable articles 20, each article comprising a main body 38 and a ring-like elastic belt 40 comprising a front belt and a back belt wherein at least the front belt or the back belt is an elastic member having an elastic member width in the transverse direction and a non-elastic region; wherein a first elastic member of a first article comprises a first non-elastic region; a second elastic member of a second article comprises a second non-elastic region; a third elastic member of a third article comprises a third non-elastic region; wherein the elastic member width of the first, second, and third elastic members are the same; and the first, second, and third non-elastic regions are different from each other.

The present disclosure relates to methods for assembling elastomeric laminates, wherein elastic material may be stretched and joined with either or both first and second substrates. First spools are rotated to unwind first elastic strands from a first unwinder in a machine direction. The first elastic strands are positioned between the first substrate and the second substrate to form an elastomeric laminate. Before the first elastic strands are completely unwound from the rotating first spools, second spools are rotated to unwind second elastic strands from a second unwinder. Subsequently, the advancement of the first elastic strands from the first unwinder is discontinued. Thus, the elastomeric laminate assembly process may continue uninterrupted while switching from an initially utilized elastic material drawn from the first spools to a subsequently utilized elastic material drawn from the second spools.
