Methods and apparatuses for making elastomeric laminates with elastic strands unwound from spools on surface unwinders

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.

Absorbent article(s) chassis comprising beamed elastics

The present disclosure relates to absorbent article's chassis 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 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. The elastics in the chassis may be oriented parallel or transverse to the longitudinal axis.

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.

The panty may include a crotch portion that exhibits a crotch longitudinal Elongation of 5 percent to 100 percent and a crotch longitudinal Tensile Modulus of 20 gf/mm to 100 gf/mm; and a crotch lateral Elongation of 50 percent to 200 percent and a crotch lateral Tensile Modulus of 2 gf/mm to 20 gf/mm. A combination of a brief panty and an absorbent pad, and an array including a brief panty product and an absorbent pad product, are also disclosed. The products are useful for management of incontinence.

DISPOSABLE ABSORBENT ARTICLE COMPRISING A CORE WITH MULTIPLE LAMINATES

Disposable absorbent articles suitable for providing leakage protection for users that experience relatively small to relatively large discharges of fluids are described. The article includes a primary topsheet, a backsheet, and an absorbent system disposed between the topsheet and the backsheet. The absorbent system includes a first absorbent core and a second absorbent core, and wherein the primary topsheet and at least the first absorbent core include a plurality of recessed areas.

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; and the first nonwoven includes an exterior surface having an average TS750 value of 5 db V2rms or less.

BEAMED ELASTIC LAMINATE PROPERTIES

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 low Average-Dtex (less than 300, less than 200, less than 100 dtex) and/or low Average-Pre-Strain (less than 300%, less than 200%, less than 100%) elastics to deliver low Pressure Under Strand (less than 1 psi according to the conditions defined by the Pressure-Under-Strand Test), while providing adequate Section-Modulus (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 100 mls of liquid), to provide for the advantages described above. Further, the elastomeric laminates of the present disclosure outperform existing laminates currently used for disposable absorbent articles as it relates to one or more key parameters (including Percent Contact Area, 2-98% Height Value, Pressure-Under-Strand, Air Permeability, Water Vapor Transmission Rate, Caliper, Caliper Retention Value, Cantilever Bending, Open Area, Section-Modulus, Rugosity Wavelength, Rugosity Frequency, Graphic Distortion Ratio).

ABSORBENT ARTICLES WITH FRANGIBLE PATHWAYS HAVING TEAR ZONES

The present disclosure relates to absorbent articles including a first belt and a second belt, the first belt and/or the second belt comprising one or more frangible pathways. The frangible pathway may comprise a first tear zone and a second tear zone extending between an inner edge and an outer edge of the first belt. The diaper pant may be configured such the tear strength of the belt is greater than the tear strength of the frangible pathway so that a first tear line propagating along the first tear zone and a second tear line propagating along the second tear zone are inclined to tear along the frangible pathway rather than in an unintended tear direction.

ABSORBENT ARTICLES WITH FRANGIBLE PATHWAYS HAVING TEAR ZONES

The present disclosure relates to absorbent articles including a first belt and a second belt, the first belt and/or the second belt comprising one or more frangible pathways. Each of the one or more substrates forming the belt has a material tear strength and the frangible pathway has a pathway tear strength. The material tear strength is greater than the pathway tear strength such that when a user tears along the one or more frangible pathways the tear propagates along the frangible pathway rather than in an unintended tear direction.
