The secondary topsheet has a first layer and a second layer. The first layer is located between the topsheet and the second layer, and a mean pore size of the first layer is larger than a mean pore size of the topsheet.

Absorbent articles with different types of channels

An absorbent article has a front side, a back side, a longitudinal axis, a liquid permeable topsheet, a liquid impermeable backsheet and an absorbent core between the topsheet and the backsheet. The absorbent core includes a first type of channels, wherein the top side and the bottom side of the core wrap are bonded to another, and a second type of channels, wherein the top side and the bottom side of the core wrap are not bonded or are less bonded to one another in this second type of channels than in the first type of channels. The absorbent material may also include cellulose and superabsorbent particles.

Absorbent articles with different types of channels

An absorbent article has a front side, a back side, a longitudinal axis, a liquid permeable topsheet, a liquid impermeable backsheet and an absorbent core between the topsheet and the backsheet. The absorbent core includes a first type of channels and a second type of channels. The first type of channels have bonds with a Static Peel Force Time which is higher than the Static Peel Force Time of the second type of channels.

Topsheet comprising natural fibers with good mechanical strength

A topsheet for use with an absorbent article is provided and comprises a first layer and a second layer. The first layer may be a spunlace nonwoven and may comprise at least 15% by weight of natural fibers by total weight of the first layer. The first layer may comprise a plurality of protrusions and a plurality of apertures. The first layer and the second layer may be in contact with each other between the majority of the protrusions. The second layer may have a plurality of apertures at least partially aligned with the apertures of the first layer.

A transfer pad is provided for use in transferring a person reclining on a bed with bed linens that includes a top sheet formed from a fluid permeable material, a bottom sheet and an absorbent core contained within the top and bottom sheet. The bottom sheet has a bottom surface formed of a material having a coefficient of friction adapted to slide on the bed linens with the patient on the transfer pad. The top and bottom sheets are connected at a fluid leak-proof seam around a perimeter of the top and bottom sheets. The absorbent core is disposed within the perimeter and includes in sequence a first tissue sheet, a fluid absorbent sheet formed of a cellulosic pulp and a super-absorbent polymer (SAP) and a second tissue sheet. The absorbent pad includes handles along each side that can be grasped by a caregiver to slide the transfer pad, with a patient thereon, across the bed linens.

UPPER LAYER SYSTEM FOR ABSORBENT ARTICLE

A feminine hygiene pad, having a topsheet of a unitary fibrous nonwoven web, is disclosed. The web includes bicomponent staple topsheet fibers having an average denier of 3.0 to 5.0 and a sheath-core bicomponent configuration, wherein the sheath component comprises polyethylene (PE) and the core component comprises polyethylene terephthalate (PET), in a weight ratio of PE:PET of 40:60 to 60:40; the fibers include hydrophobic fibers; and the web includes inter-fiber bonds randomly distributed therewithin along the x-, y- and z-directions, wherein the inter-fiber bonds are present where sheaths of adjacent fibers are fusion-bonded together without compression.

A feminine hygiene pad having a topsheet including a fibrous nonwoven web material having hydrophilic fibers, and an absorbent layer including an open-celled foam formed through polymerization of a high internal phase emulsion (HIPE) is disclosed. The topsheet and the absorbent layer are disposed in direct face-to-face relationship with each other, and attached to each other within a bonding region. Within the bonding region, each first identifiable point of attachment between the topsheet and the absorbent layer has a neighboring second identifiable point of attachment between the topsheet and the absorbent layer within a 6 mm radius of the first identifiable point of attachment.

ABSORBENT ARTICLE WITH CONFORMING FEATURES

An absorbent has longitudinal and lateral centerlines, first, second, and target regions, the target region being disposed between the first second regions. Each of the first, second target regions extend laterally across the disposable absorbent article. The disposable absorbent article also has a topsheet; a backsheet; an absorbent core disposed between the topsheet and backsheet; a fluid management layer disposed between the topsheet and absorbent core; and a target zone disposed in the target region. The target zone has a first plurality of conforming features in at least the absorbent core or a combination of the absorbent core and at least one of the topsheet or fluid management layer. The absorbent article also has a long fiber network.

Absorbent structure with stratified distribution layer

An absorbent structure including a distribution layer and a storage layer is disclosed. The distribution layer has two or more stratums. The two or more stratums include a body facing stratum and a subsequent stratum below the body facing stratum. The density of the subsequent stratum is a fraction of the density of the body facing stratum and the porosity of the subsequent stratum is a multiple of the body facing stratum porosity.

Topsheet comprising natural fibers

A topsheet for an absorbent article is provided and has at least a first layer. The first layer comprises at least 15% by weight of natural fibers by total weight of the first layer.
