An absorbent article comprising a hotmelt adhesive comprising a styrene-block-copolymer (SBC), an amorphous polyolefin and optionally a tackifier. The SBC is preferably selected from the group of SEBS, SEPS and SEP polymers, and the amorphous polyolefin is preferably a propylene-based copolymer (PbP) having a weight-average molecular weight Mw of less than 10 000 g/mol. The hotmelt adhesive bonds two components of the article, for example SAP particles on the core wrap.

Absorbent articles comprising a SBC based hotmelt adhesive

An absorbent article such as a baby diaper comprising a three-dimensional laminatehaving a first layerintermittently bonded to a second layerby a heterophase polymer. The topsheet comprises three-dimensional protrusionsin the first layerwhich are not bonded to the second layer. The heterophase polymer has an enthalpy of fusion of at least 10 J/g. The laminate may be used on the wearer-facing side of the article as topsheetand/or on the garment-facing side as part of the backsheet. The first layer may comprise natural fibers.

Absorbent article with three-dimensional hot-melt bonded laminate

Described herein is an absorbent article. The absorbent article includes an assembly of components and an adhesive composition joining at least two of the assembly of components together. The adhesive composition includes from about 50 wt. % to about 80 wt. % of one or more copolymers and a blend of one or more heterophase copolymers. The one or more copolymers include from about 30 mole % to about 70 mole % of monomer units selected from ethylene. 1-butene, and mixtures thereof. The one or more copolymers also include from about 30 mole % to about 70 mole % of propene monomer units. The adhesive composition is free of polyisobutylene and has a viscosity of from about 2,000 mPa·s to about 11,500 mPa·s at 150° C.

Absorbent article comprising an adhesive composition

An absorbent article having improved adhesive attachment means to secure the absorbent article in the crotch region of a garment. The adhesive attachments means of this invention consists of an adhesive exhibiting reduced migration.

Adhesive attachment for absorbent article

An absorbent article (′) comprising a topsheet (), a backsheet (), and an absorbent core (), and at least one nonwoven-nonwoven adhesive bond other than a core stabilization bond, wherein the adhesive of the adhesive bond has a Toughness of at least 11 MJ/m, a Yield Stress of at least 0.7 MPa. The adhesive may further have a storage modulus G′ of at least 7.5 MPa. These are as measured at 37° C. according to the methods described herein. The adhesive comprises at least 5% by weight of the adhesive of a tackifier.

Absorbent article with high toughness adhesive

A hotmelt composition comprising, a low molecular weight metallocene-catalyzed polymer, a high molecular weight polymer, an amorphous polyolefin and a tackifier. The hotmelt composition is particularly useful in absorbent articles such as diapers. The hotmelt composition provides especially good nonwoven-film bonds but can also be used for nonwoven-nonwoven bonds.

Tackified hotmelt adhesive composition

A hotmelt composition comprises at least three co-polymers defined by their chemistry and molecular weight. The hotmelt composition may be without tackifiers. The hotmelt can be used in absorbent articles such as diapers comprising two substrates at least partially attached by the hotmelt composition. The hotmelt provides especially good nonwoven-nonwoven bond and nonwoven-film bond.

Hotmelt composition comprising three polymers having different peak molecular weights

An absorbent article, preferably a disposable absorbent article such as a diaper, is disclosed having an absorbent core which imparts increased wearing comfort to the article and makes it thin and dry. The absorbent core useful for an absorbent article comprises a substrate layer, a discontinuous layer of absorbent material, and a layer of thermoplastic material. A second surface of the discontinuous layer of absorbent material is in at least partial contact with a first surface of the substrate layer. Portions of a second surface of the layer of thermoplastic material are in direct contact with the first surface of the substrate layer and portions of said second surface of the layer of thermoplastic material are in direct contact with a first surface of the discontinuous layer of absorbent material. A process for providing a storage layer for an absorbent core useful in an absorbent article is further disclosed.

Thin and dry diaper

Described herein is an absorbent article having an absorbent core. The absorbent core includes a superabsorbent polymer material and a superabsorbent polymer immobilizing material. The superabsorbent polymer immobilizing material includes from about 20% to about 70% of a first polymer and from about 30% to about 80% of a second polymer. The superabsorbent polymer immobilizing material has a Shear Viscosity at 10 (1/s) at 230&#xb0; C. of from about 300 mPa&#xb7;s to about 10,000 mPa&#xb7;s.

Absorbent cores comprising a superabsorbent polymer immobilizing material

Grafted, crosslinked cellulosic materials include cellulose fibers and polymer chains composed of at least one monoethylenically unsaturated acid group-containing monomer (such as acrylic acid) grafted thereto, in which one or more of said cellulose fibers and said polymer chains are crosslinked (such as by intra-fiber chain-to-chain crosslinks). Some of such materials are characterized by a wet bulk of about 10.0-17.0 cm3/g, an IPRP value of about 1000 to 7700 cm2/MPa&#xb7;sec, and/or a MAP value of about 7.0 to 38 cm H2O. Methods for producing such materials may include grafting polymer chains from a cellulosic substrate, followed by treating the grafted material with a crosslinking agent adapted to effect crosslinking of one or more of the cellulosic substrate or the polymer chains. Example crosslinking mechanisms include esterfication reactions, ionic reactions, and radical reactions, and example crosslinking agents include pentaerythritol, homopolymers of the graft species monomer, and hyperbranched polymers.
