METHODS AND APPARATUSES FOR MAKING ELASTOMERIC LAMINATES WITH ELASTIC STRANDS
20220000676 · 2022-01-06 ·

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.

FLUID MANAGEMENT LAYER FOR AN ABSORBENT ARTICLE

A fluid management layer having a basis weight of between about 40 grams per square meter (gsm) and about 120 gsm is described. The fluid management layer has a plurality of absorbent fibers, a plurality of stiffening fibers and a plurality of resilient fibers, wherein the absorbent fibers are present at about 20 percent to about 75 percent by weight, and wherein the integrated, carded, staple fiber, nonwoven has a first side and a second side, and wherein there is a higher number of absorbent fibers on the first side or second side versus the other.

STRETCH LAMINATE WITH BEAMED ELASTICS AND FORMED NONWOVEN LAYER

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.

FEMININE HYGIENE ARTICLE WITH IMPROVED WINGS

Feminine hygiene articles are disclosed herein. The feminine hygiene articles described herein can provide easily discernable placement and orientation guides which reduce the likelihood of misapplication by the user, facilitated attachment guides which can reduce the likelihood of misapplication of the feminine pad, and can also reduce the likelihood of improper attachment of the feminine pad to a panty. The feminine hygiene articles disclosed include uniquely shaped wings which can provide cues on proper attachment of the article to the panty and may help in providing sustained coverage of the feminine hygiene article to the panty which reduces the likelihood that the pad will become detached during use.

PATTERNED APERTURED WEBS

A patterned apertured web is disclosed. The patterned apertured web includes a plurality of land areas in the patterned apertured web and a plurality of apertures defined in the patterned apertured web. At least some land areas of the plurality of land areas surround at least some apertures of the plurality of apertures. The patterned apertured web has an Effective Open Area in the range of about 3% to about 30%, according to the Aperture Test herein. The patterned apertured web has a plurality of Interaperture Distances, according to the Aperture Test herein. The Interaperture Distances have a distribution having a median and a mean. The plurality of apertures include a first set of apertures defining a first shape and a second set of apertures defining a second shape.

ARRAY OF DISPOSABLE ABSORBENT ARTICLES HAVING A SEQUENCE OF GRAPHICS CORRESPONDING TO A WEARER'S STAGES OF DEVELOPMENT

An array of disposable absorbent articles comprising a sequence of graphic designs corresponding to a wearer's stage of development.

Patterned apertured webs

A patterned apertured web is disclosed. The patterned apertured web includes a plurality of land areas in the patterned apertured web and a plurality of apertures defined in the patterned apertured web. At least some land areas of the plurality of land areas surround at least some apertures of the plurality of apertures. The patterned apertured web has an Effective Open Area in the range of about 3% to about 30%, according to the Aperture Test herein. The patterned apertured web has a plurality of Interaperture Distances, according to the Aperture Test herein. The Interaperture Distances have a distribution having a median and a mean. The plurality of apertures include a first set of apertures defining a first shape and a second set of apertures defining a second shape.

Shaped nonwoven

A through-air thermally bonded nonwoven fabric is provided. The nonwoven fabric can include a first surface and a second surface and a visually discernible pattern of three-dimensional features on one of the first or second surface. Each of the three-dimensional features can define a microzone comprising a first region and a second region. The first and second regions can have a difference in values for an intensive property, wherein at least one of the surfaces has a TS7 value of less than about 15 dB V.sup.2 rms, and wherein the first surface has a TS7 value that is higher than the second surface TS7 value.

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.

Inline high-speed manufacturing and printing of absorbent products

The present invention methods for manufacturing absorbent articles that involve the placement of absorbent cores having variable absorbency levels on consecutively aligned absorbent articles within the same manufacturing line. Additionally, the present invention also includes the provision of single packages of disposable absorbent articles that contain a first absorbent article having a first absorbency level and a second absorbent article having a second absorbency level, wherein the second absorbency level is higher than the first absorbency level.
