WRAPPER FOR ABSORBENT ARTICLE
The disclosure pertains to a wrapper (22) for an absorbent article (10) comprising a release paper (51,51′) comprising a layer of cellulosic fibers (33), a layer of peeling agent (32) arranged onto the layer of cellulosic fibers (33). According to the disclosure, the layer of cellulosic fibers (33) comprises a basis weight comprised between 10 gsm and 40 gsm. The disclosure also relates to an assembly comprising an absorbent article (10) and such wrapper (22) and a process to manufacture such assembly (10).
THREE-DIMENSIONAL MATERIALS
An absorbent article comprises a laminate, a backsheet, and an absorbent core disposed at least partially between the laminate and the backsheet. The laminate comprises a nonwoven, non-apertured topsheet and a nonwoven, non-apertured acquisition layer. The topsheet is less hydrophilic than the acquisition layer. The laminate comprises a generally planar first region and a plurality of discrete integral second regions formed in the topsheet and the acquisition layer to nest portions of the topsheet and the acquisition layer. The plurality of discrete integral second regions each comprise a wearer-facing surface. A non-uniform interruption is defined in the topsheet in each of at least some of the plurality of discrete integral second regions. Portions of the acquisition layer form portions of the wearer-facing surface in the non-uniform interruption in the at least some of the discrete integral second regions.

The present disclosure is directed, in part, to an absorbent article comprising a liquid management system (LMS) and an absorbent core disposed at least partially intermediate a topsheet and a backsheet. The LMS defines one or more channels therein. The one or more channels of the LMS may at least partially overlap or not overlap with channels defined in the absorbent core.
Absorbent cores and methods for forming absorbent cores
Pulpless absorbent cores and methods of manufacture are disclosed. A first exemplary absorbent core may comprise a carrier sheet having a first edge region, a central region, and a second edge region and particulate material disposed on the carrier sheet through the first edge region, the central region, and the second edge region. The absorbent core may additionally have an absorbent core width and the central region may have a central region width, and the central width may comprise between 33% and 75% of the absorbent core width. Further, the central region may comprise an average basis weight of particulate material that is at least 110% of an average basis weight of particulate material within at least one of the left edge region and the right edge region.
Absorbent article
An objective is to provide an absorbent article that can prevent backflow and can reduce water retention in a front sheet as much as possible. In an incontinence pad 1 for use with a medium or larger volume that absorbs 20 cc or a larger volume of urine, a front sheet 3 is formed by coating a water repellent on a spunlace nonwoven fabric that is made of 100 wt. % of cotton fiber. On a skin facing surface side, in a plan view, recess part lines 20, 21 of a diamond-shaped lattice pattern are formed from many first recess part lines 20 that go along a predetermined inclination angle direction and are formed with a constant gap in the pad longitudinal direction and many second recess part lines 21 that go along the inclination angle direction obtained by reversing the first recess part lines 20 in a width direction by the pad longitudinal direction and are formed with a constant gap in the pad longitudinal direction, partition areas 22 of a diamond-shaped lattice shape partitioned by these recess part lines 20, 21 are arranged adjacently in the longitudinal direction and the width direction. Furthermore, many open holes 10 penetrating through both sides are formed at least at an excretion hole corresponding part H.
ABSORBENT ARTICLE WITH TOPSHEET COMPRISING CELLULOSE-BASED FIBERS
The present disclosure relates to an absorbent article comprising a wearer-facing surface and an opposite garment-facing surface. The absorbent article comprises a liquid pervious topsheet, a liquid impervious backsheet, and an absorbent core disposed between the topsheet and the backsheet. The topsheet comprises a nonwoven substrate comprising cellulose-based fibers, a first surface and an opposite second surface. The first surface of the nonwoven substrate forms at least part of the wearer-facing surface. The first surface comprises a first area having a first contact angle no less than about 100°, as measured by Contact Angle Test, and the second surface comprises a second area having a second contact angle no less than about 82°, as measured by Contact Angle Test. The second contact angle is smaller than the first contact angle.
Absorbent article
In order to absorb a small amount of liquid, to prevent an absorbent article from being disintegrated by the absorbed liquid, and to prevent piping of a toilet from being clogged even if the absorbent article is flushed into a flush toilet, the absorbent article includes a pulp layer containing a crushed pulp or fibers mainly containing a crushed pulp, and the pulp layer has a water repellent surface layer portion formed by applying a water repellent agent to at least one surface layer portion.
Absorbent articles with different types of channels
An absorbent article has a front side, a back side, a longitudinal axis and includes a liquid permeable topsheet on the wearer-facing side, a liquid impermeable backsheet on the garment-facing side, and an absorbent core between the topsheet and the backsheet. The absorbent core includes a core wrap having a top side and a bottom side, an absorbent material having a deposition area between the top side and the bottom side of the core wrap, and at least two channels substantially free of absorbent material within the deposition area. In a first type of channels, the top side and the bottom side of the core wrap are bonded to each other. In a second type of channels, the top side and the bottom side of the core wrap are not bonded or are less bonded to each other than in the first type of channels.
ABSORBENT ARTICLE WITH HYBRID NONWOVEN WEB
An absorbent article comprises a topsheet, a backsheet, and an absorbent core positioned between the topsheet and the backsheet. The absorbent article comprises a nonwoven web. The nonwoven web having a first side and a second side. The nonwoven web comprises thermoplastic fibers and cellulosic fibers. At least a portion of the thermoplastic fibers are present on the first side and at least a portion of the cellulosic fibers are present on the second side. The nonwoven web has a pattern of discrete bond points, wherein the pattern of discrete bond points has a fiber free-length parameter, as defined by the Fiber Free-Length Test, with a value of less than 2.90 mm The second side of the nonwoven web forms part of an exterior surface of the absorbent article.
NONWOVEN AND ABSORBENT ARTICLES CONTAINING THE SAME
The present disclosure relates to an absorbent article comprising a liquid pervious topsheet, a liquid impervious backsheet, an absorbent core disposed between the topsheet and the backsheet, and an intermediate layer disposed between the topsheet and the absorbent core, wherein the intermediate layer comprises a nonwoven which comprises a plurality of apertures, absorbent fibers, and ultrafine fibers. The nonwoven comprises the ultrafine fibers of about 3% to about 35% by weight of the nonwoven, and at least most of the plurality of apertures have a hydraulic diameter in the range of about 600 μm to about 4500 μm.
