An absorbent article is provided, the absorbent article comprising a nonwoven material. The nonwoven material comprises core/sheath bicomponent fibers wherein the core is formed of PET resin. The present disclosure also provides a wipe comprising a nonwoven material, the nonwoven material comprising core/sheath bicomponent fibers wherein the core is formed of PET resin. The PET has less than 150 ppm of antimony.

A process of making an absorbent article comprising providing a liquid permeable topsheet web extending substantially continuously in a machine direction. The topsheet web having a first and second surface and a backsheet web extending substantially continuously in the machine direction and an acquisition layer having a first and second surface. The process comprises aligning the topsheet web and the acquisition layer in a face to face relationship such that the second surface of the topsheet in in contact with the first surface of the acquisition layer and simultaneously mechanically deforming and combining the topsheet web together with the acquisition layer. The topsheet web and acquisition layer are nested together such that a majority of the three-dimensional protrusions formed in the topsheet web coincide with and fit together with a majority of the three-dimensional protrusions formed in the acquisition layer to provide a topsheet/acquisition layer laminate web having three-dimensional protrusions.

A pant type disposable absorbent product comprising a front body panel, a back body panel positioned at a distance from said front body panel, and an absorbent member, said absorbent product having a longitudinal central axis X-X and a transverse central axis Y-Y; said front body panel being substantially rectangular, and having a waist edge, two side edges, and an inward edge comprising a crotch edge, and leg opening edges on each side of the crotch edge, between the crotch edge and each side edge, said front body panel being at least partially elasticized, said back body panel having a waist edge, two side edges, a crotch edge, and leg opening edges on each side of the crotch edge, between the crotch edge and each side edge, wherein a distance from the crotch edge to the waist edge is greater than the length of the side edges.

The invention relates to slit absorbent articles and the use of slits in absorbent materials to provide improved liquid intake rate, flexibility and softness compared to the unmodified material. The absorbent material, including superabsorbent materials, are particularly useful as absorbent cores in disposable absorbent articles such as diapers, incontinent products, sanitary napkins and the like.

A fluff pulp is provided, which comprises softwood fibers; and 3 to 35% by weight of hardwood fibers. A fluff is also provided, which comprises the fiberized or shredded fluff pulp. A core is also provided, which comprises the fluff and at least an SAP. Processes for making and using the fluff pulp, fluff, and core are provided, and products made thereby.

An absorbent article comprising an absorbent core sandwiched between a liquid permeable topsheet and a liquid impermeable backsheet, and an acquisition distribution layer positioned between said topsheet and said absorbent core, wherein the absorbent core comprises absorbent material selected from the group consisting of cellulose fibers, superabsorbent polymers and combinations thereof, wherein said absorbent core comprises at least one core wrap substrate enclosing said absorbent material, and wherein a top layer of said core wrap is adhered to a bottom layer of said core wrap to form one or more channels substantially free of said absorbent material, wherein said channels have a length extending along a longitudinal axis and the absorbent core has a length extending along said longitudinal axis and wherein the length of said channels is from 10% to 95% of the length of said absorbent core and wherein said channels each follow a substantially continuous path such as from a first end of a channel to a second end of the same channel wherein the acquisition distribution layer comprises a spunbond and/or carded nonwoven layer comprising synthetic fibers, wherein said synthetic fibers are comprised at a level of greater than 80% wt by weight of said acquisition distribution layer, and wherein said acquisition distribution layer has a basis weight of from 10 to 50 g/m.sup.2.

An absorbent core for use in an absorbent article, the absorbent core extending in a transversal direction and a longitudinal direction. The absorbent core includes a fluid-permeable top layer, a bottom layer, and a central layer between the top layer and the bottom layer. The central layer may be a high loft fibrous nonwoven layer, in particular having a density of less than about 0.200 g/cc, measured at a pressure of 4.14 kPa. Superabsorbent polymer particles may be blended with the fibers of the central layer, except for one or more longitudinally-extending channels substantially free of superabsorbent polymer particles.

Catalysts for dehydrating hydroxypropionic acid, hydroxypropionic acid derivatives, or mixtures thereof to acrylic acid, acrylic acid derivatives, or mixtures thereof with high yield and selectivity, short residence time, and without significant conversion to undesired side products, such as, for example, acetaldehyde, propionic acid, and acetic acid, are provided. The catalysts are mixed condensed phosphates. Methods of preparing the catalysts are also provided.

An absorbent structure including a dryness layer laminate is disclosed, with the structure suitable for use in disposable absorbent products such as for infant or incontinence care. The dryness layer laminate is positioned adjacent an associated absorbent core, between the absorbent core and the wearer, for enhancing surface dryness and comfort for the wearer. The dryness layer laminate comprises adhesive fibers or filaments, and particulate superabsorbent, and is configured to permit liquid to pass through the laminate to the associated absorbent core, while acting to remove liquid from the surface of the absorbent structure positioned adjacent to the wearer.

An absorbent article comprising an absorbent member positioned between a topsheet and a backsheet is provided. The absorbent member contains at least one layer that comprises superabsorbent particles containing nanopores having an average cross-sectional dimension of from about 10 to about 500 nanometers.
