A High Internal Phase Emulsion (HIPE) foam having cellulose nanoparticles.

Open-cell foam having a structure of interconnected struts formed of polymeric material and defining open cells, resulting from polymerization of a continuous phase of a high internal phase water-in-oil emulsion, the struts comprising the polymeric material with clay nanoparticles at least partially captured therewithin, is disclosed. The clay nanoparticles may be present in combination with a surface modifier. Methods for making the open-cell foam are also disclosed. Absorbent articles including the open cell foam are also disclosed.

An absorbent disposable article, such as a diaper, panty diaper, panty liner, sanitary napkin or incontinence device is disclosed. The article has a porous polymer-based structure obtainable by a process of: (a) depositing and photopolymerizing, layer-by-layer in accordance with a predetermined 3D model, an emulsion having an external continuous phase surrounding droplets of an internal phase having has one or more photopolymerizable monomers and/or oligomers and a photopolymerization initiator; and (b) removing the internal phase from the continuous polymer phase formed from the one or more photopolymerizable monomers and/or oligomers. The process produces a monolithic porous structure having three types of pores: (i) pores resulting from the location from which the internal phase was removed, (ii) pores interconnecting the pores according to (i), and (iii) pores as predetermined by the 3D model. The invention also relates to a method of making the article.

The present disclosure relates to homogeneous or heterogeneous polymer foam structures having a graphic printed thereon. As discussed herein, foam structures, such as for example High Internal Phase Emulsion (HIPE) foam structures may include a first surface and a second surface opposite the first surface, and one or more graphics may be printed directly on the first and/or second surfaces of the foam. The graphic may comprise ink positioned on the first and/or second surface, wherein the ink may penetrate into the foam structure below the surface on which the ink is applied. As such, the ink may reside on the foam structure and/or within the foam structure at various depths below the first and/or second surface.

An absorbent structure comprising a heterogeneous mass comprising one or more enrobeable elements and one or more discrete open cell foam pieces wherein at least one of the discrete open cell foam pieces comprises a first vacuole and a second vacuole wherein the first vacuole has a first cross sectional area, wherein the second vacuole has a second cross sectional area, wherein the first vacuole enrobes a first enrobeable element, wherein the second vacuole enrobes a second enrobeable element, wherein the first enrobeable element and the second enrobeable element exhibit different surface properties.

The present disclosure provides a sanitary napkin that is thin, highly absorbent and has resiliency properties that are selected to provide good comfort potential and at the same time reduce the likelihood of deformation and breaking. In a specific example, the sanitary napkin comprises a cover layer, an absorbent system and a barrier layer. The absorbent system includes an absorbent core and a reinforcement layer.

A product including a feminine hygiene pad in a folded configuration provided within an individualized envelope package is disclosed. The pad is folded separately of the envelope package and is entirely contained within the package. The package has a rectangular shape and includes a section of polymeric film, a pair of side seams, and a closure flap overlapping an opening edge, wherein the package is configured to create an access opening upon lifting of the closure flap, while allowing material along the side seams to remain unseparated.

An absorbent article. The absorbent article includes a topsheet having a body contacting surface, a backsheet joined to said topsheet, and an absorbent core disposed between the topsheet and the backsheet, wherein the absorbent core has an upper layer and a lower layer.
