ABSORBENT ARTICLE HAVING WAIST GASKETING ELEMENT
20230233383 · 2023-07-27 ·

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 chassis having a topsheet, a backsheet, and an absorbent core disposed between the topsheet and backsheet. A waist gasketing element is joined to the chassis and disposed in one of the first waist region or the second waist region. The waist gasketing element has a top layer and a bottom layer, and first area, A1. The top layer is bonded to the bottom layer in a closure bond region by a closure bonding technique. The closure bond region has an aggregate closure bond area, BA, which is less than 60% of the first area, A1.

Absorbent article having waist gasketing element

Methods of forming front and back waist gasketing elements on an absorbent article are provided. The methods include the steps of providing a web of chassis material and waist gasketing elements, each having a first transverse edge, a second transverse edge, a top and bottom layer. The methods further include bonding the top and bottom layers in closure bond regions, and joining the waist gasketing elements to the chassis to form a strip of final articles. The methods include dividing the strip of final articles between the first and second transverse edges such that a cut separates two final articles, a leading article and a trailing article, wherein each cut is disposed within a closure bond region, forms a back waist edge of the leading article and a front waist edge of the trailing article; and forms an outboard lateral edge of a back waist gasketing element on the leading article and an outboard lateral edge of a front waist gasketing element on the trailing article.

Disclosed is an absorbent core composite for a disposable absorbent article. The absorbent composite has a first fabric, a body side second fabric, and a plurality of aggregates of superabsorbent particles (SAP) situated between the first fabric second fabric. About each of a plurality of the SAP aggregates, an arrangement of spaced apart bond sites secures the second fabric to the first fabric and form a pocket in which the SAP aggregate is secured between the first fabric and the second fabric. The body side second fabric is a bulky nonwoven including fibers that entangle at least some particles in the SAP aggregate.

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 having a topsheet, a backsheet, and an absorbent core disposed between the topsheet and backsheet. A waist gasketing element is joined to the chassis and disposed in one of the first waist region or the second waist region. The waist gasketing element has a top layer and a bottom layer, an inboard lateral edge and an outboard lateral edge, and first area, A1. The top layer is bonded to the bottom layer in a closure bond region by a closure bonding technique. The closure bond region has an aggregate closure bond area, BA, which is at least about 10% of the first area, A1.

Water-absorbing resin particles are disposed, the water-absorbing resin particles including: a polymer particle containing a crosslinked polymer having a monomer unit derived from an ethylenically unsaturated monomer including at least one kind of compound selected from the group consisting of (meth)acrylic acid and a salt thereof; and a plurality of inorganic particles disposed on a surface of the polymer particle, in which a proportion of a (meth)acrylic acid and a salt thereof is 70 to 100 mol % with respect to a total amount of monomer units in the crosslinked polymer. In a case where a water absorption speed index I=(value of non-pressurization DW after 10 seconds)×6 [mL/g], and a water absorption speed index II=(value of non-pressurization DW after 3 minutes)/3 [mL/g], a static suction index α calculated by the following formula:


α=(I+II)/2

is 5.0 mL/g or higher.
