Disposable Floating Absorbent Core and Disposable Absorbent Assembly Including Same, and Method of Making Same
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.
Methods and apparatuses for making elastomeric laminates with elastic strands provided with a spin finish
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.
Methods and apparatuses for making elastomeric laminates
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.
Absorbent articles comprising stretch laminates
An absorbent article includes a chassis comprising 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 an ultrasonically bonded stretch laminate. The stretch laminate includes a first nonwoven and a second nonwoven, and an elastomeric film sandwiched between the first and second nonwovens. The elastomeric film has two surfaces and a skin on at least one of the surfaces. The stretch laminate further incudes a first zone and second zone. In the second zone, the laminate is elastically extensible in a stretch direction. In the first zone, the laminate is unactivated and the elastomeric film comprises activation stripes.
METHODS AND APPARATUSES FOR MAKING ELASTOMERIC LAMINATES
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.
Methods and apparatuses for making elastomeric laminates with elastic strands
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.
HIP-TO-WAIST AND WAIST-TO-CROTCH SILHOUETTE(S) OF ABSORBENT ARTICLE(S) COMPRISING BEAMED ELASTICS
The present disclosure relates to absorbent articles comprising belts comprising 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 low decitex (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 Test in the Method below) under the elastics, while providing adequate modulus of (between about 2 gf/mm and 15 gf/mm), resulting in a Product Hip-to-Waist Silhouette from about 0.8 to about 1.1 and a Product Waist-to-Crotch Silhouette from about 0.8 to about 2.0 to provide for the advantages described above.
Absorbent article having waist gasketing element
An absorbent article for wearing about the lower torso of a wearer includes a first waist region having a first waist edge, a second waist region having a second waist edge, and a crotch region disposed between the first and second waist regions. The article further includes a first longitudinal edge, a second longitudinal edge, and a chassis comprising a topsheet, a backsheet, and an absorbent core disposed between the topsheet and backsheet. A waist gasketing element is disposed in one of the first or the second waist regions and joined to the chassis in a chassis attachment region. The waist gasketing element comprises an outboard lateral edge and an inboard lateral edge. The chassis attachment region comprises a first zone proximate to the outboard lateral edge and a second zone disposed longitudinally inboard of the first zone. Each of the first and the second zones comprise one or more chassis attachment bonds. The first zone comprises a first total basis weight and the second zone comprises a second total basis weight, wherein the second total basis weight is greater than the first total basis weight.
ELASTOMERIC LAMINATE WITH SOFT NONCRIMPED SPUNBOND FIBER WEBS
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 first nonwoven and second nonwoven and an elastomeric material sandwiched between said first and second nonwovens. The laminate further includes a plurality of ultrasonic bonds.
LAMINATE(S) COMPRISING BEAMED ELASTICS AND ABSORBENT ARTICLE(S) COMPRISING SAID LAMINATE(S)
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.
