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, 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

The invention relates to thermoplastic molding compounds having melt viscosities of less than 30,000 mPas for use as a hot-melt adhesive, comprising the components A and B, wherein component A comprises one or more C/Ccopolymers each produced with metallocene catalysts and each having a melt viscosity at 170&#xb0; C. of less than 20,000 mPas, measured according to DIN 53019, and a molecular weight Mof 1000 g/mol to 50,000 g/mol, and component B comprises one or more C/Ccopolymers each produced with metallocene catalysts and each having a melt flow index MI of 1 to 100 g/m in, measured at 190&#xb0; C./2.16 kg, according to ASTM D 1238, and a molecular weight Mof 50,000 g/mol to 300,000 g/mol. Said thermoplastic molding compounds, because of the viscosity and mechanical properties thereof, are suitable for fiber mesh applications.

Thermoplastic molding compounds

An absorbent article, preferably a disposable absorbent article such as a diaper, is disclosed that provides an improved immobilization of absorbent polymer material when the article is fully or partially urine loaded. This absorbent core is useful for providing an absorbent article of increased wearing comfort. Specifically disclosed is an absorbent core useful for an absorbent article comprising a substrate layer and absorbent material, the absorbent material comprising an absorbent polymer material, the absorbent material optionally comprising absorbent fibrous material, the absorbent fibrous material not representing more than 20% of the weight of absorbent polymer material, wherein the absorbent material is immobilized when wet such that the absorbent core achieves a wet immobilization of more than 50%, preferably of more than 60%, 70%, 80% or 90% according to the Wet Immobilization Test described herein.

Comfortable diaper

An absorbent article, preferably a disposable absorbent article such as a diaper, is disclosed that provides an improved immobilization of absorbent polymer material when the article is fully or partially urine loaded. This absorbent core is useful for providing an absorbent article of increased wearing comfort. Specifically disclosed is an absorbent core useful for an absorbent article comprising a substrate layer and absorbent material, the absorbent material comprising an absorbent polymer material, the absorbent material optionally comprising absorbent fibrous material, the absorbent fibrous material not representing more than 20% of the weight of absorbent polymer material, wherein the absorbent material is immobilized by a thermoplastic fibrous material.

An absorbent article comprising a malodor reduction composition. The malodor reduction composition comprises a perfume mixture comprising about 5% to about 100%, by weight of said perfume mixture, of at least two perfume materials selected from the group consisting of terpinyl acetate, methyl iso-eugenol, phenyl acetaldehyde dimethyl acetal, and patchone.

Articles comprising malodor reduction compositions

An absorbent structure for an absorbent article, comprising a first substrate and an absorbent layer supported thereon, said absorbent layer comprising an absorbent material comprising a superabsorbent polymer material; wherein said absorbent structure comprises a fiberized net structure to at least partially immobilize said absorbent layer onto said first substrate, and whereby said fiberized net structure has a storage modulus (G') at 21&#xb0; C. of greater than about 1.2&#xd7;10Pa.

Absorbent articles with improved strength

Absorbent articles and absorbent core structures with improved core strength and stability with long core end seal and channel hang times.

Absorbent articles with improved cores

An absorbent structure comprising absorbent polymer particles supported by a substrate layer and immobilized on this substrate layer by a thermoplastic adhesive material and further comprising a component sorbing oily substances that may migrate from the thermoplastic adhesive material is disclosed. The absorbent structure can be suitably incorporated in a disposable absorbent article.

Absorbent structure comprising an oil-scavenger component

A process is provided for making a bond between a first, relative hydrophilic nonwoven and a second relatively less hydrophilic nonwoven by use of a construction adhesive, by applying the adhesive only to the first more hydrophilic nonwoven; also provided are absorbent cores for absorbent article comprising such bonded nonwovens, and such absorbent articles.
