Absorbent article with an ear portion
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 further includes a chassis comprising a topsheet, a backsheet, and an absorbent core disposed between the topsheet and backsheet; and an ear. The ear includes a laminate having a first nonwoven and second nonwoven and an elastomeric material sandwiched between said first and second nonwovens. The laminate comprises a plurality of ultrasonic bonds. The ear also has a first inelastic region and an elastic region. The ear is joined to the chassis in the first inelastic region, and a fastening system is joined to the ear in the elastic region.
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 methods and apparatuses may be configured with a plurality of elastic strands wound onto a beam, wherein one or more elastic strands comprises a spin finish. During assembly of an elastomeric laminate, the beam is rotated to unwind the elastic strands from the beam. A portion of the spin finish may be removed from the advancing elastic strand with a spin finish removal apparatus. The spin finish removal apparatus may be configured to apply detergent to an advancing elastic strand and may also wipe and/or dry the advancing elastic strand. The treated stretched elastic strand may then be connected between a first substrate and a second substrate. In some configurations, adhesive may be applied to the treated the elastic strand, the first substrate, and/or the second substrate.
ABSORBENT ARTICLE WITH LEG GASKETING CUFF
A disposable absorbent article may include a topsheet, a backsheet, an absorbent core disposed between the topsheet and the backsheet, and a leg gasketing system. 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.
ABSORBENT ARTICLE WITH A LOWER INTERMEDIATE LAYER PARTIALLY BONDED TO THE ABSORBENT CORE
An absorbent article comprising a liquid permeable topsheet, a backsheet, an absorbent core comprising an absorbent material and a core wrap is provided. The article comprises an intermediate layer between the bottom side of the core wrap and the backsheet. The intermediate layer and the absorbent core are only partially bonded to each other at their interface and the interface comprises a bonded portion and a unbonded portion. The intermediate layer can at least partially decouple from the absorbent core in the unbonded portion, which increases flexibility of the article in the transversal direction.
Absorbent articles with improved low viscosity waste acquisition
An absorbent article includes a liquid permeable, apertured topsheet, a liquid impermeable backsheet, an absorbent core disposed at least partially intermediate the topsheet and the backsheet, and an acquisition material disposed at least partially intermediate the topsheet and the absorbent core. The acquisition material has a caliper in the range of about 2.5 mm to about 10 mm, according to the Caliper Test, and an Air Permeability in the range of about 5,000 l/m.sup.2/s to about 11,000 l/m.sup.2/s, according to the Air Permeability Test. The acquisition material has a first surface, a second surface, and a plurality of three-dimensional features extending outwardly from the first surface or the second surface.
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.
ABSORBENT PADS AND GARMENTS
A pad for a garment includes a body and capping. The body has a front, a rear and a periphery and includes one or more absorbent layers for absorbing liquid and a gas-permeable barrier overlying the one or more absorbent layers to block the liquid. The capping runs along and caps at least a portion of the periphery to block the liquid. The capping has a front portion overlying the front, a rear portion overlying the rear, and a mounting portion, projecting away from the body, for mounting the pad.
Methods and apparatuses for making elastomeric laminates with elastic strands unwound from beams
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. A first beam is rotated to unwind a first plurality of elastic strands from the first beam in the machine direction. The first plurality of elastic strands are positioned between the first substrate and the second substrate to form the elastomeric laminate. Before the first plurality of elastic strands are completely unwound from the first beam, a second beam is rotated to unwind the second plurality of elastic strands from the second beam. Subsequently, the advancement of the first plurality of elastic strands from the first beam is discontinued. Thus, the elastomeric laminate assembly process may continue uninterrupted while switching from an initially utilized elastic material drawn from the first beam to a subsequently utilized elastic material drawn from the second beam.
Shaped Nonwoven
A nonwoven fabric including continuous filaments forms the nonwoven fabric. The nonwoven fabric having a first surface, a second surface, and a visually discernible zone on the second surface and extending from the first surface. The visually discernible zone has a pattern of three-dimensional features. The first surface is relatively flat. A first plurality of the three-dimensional features have different Z-direction maximum dimensions relative to the first surface. A second plurality of the three-dimensional features have substantially the same Z-direction maximum dimensions relative to the first surface. Each of the three-dimensional features define a microzone comprising a first region and a second region. The first and second regions have a difference in values for an intensive property.
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.
