In the absorbent portion of the absorbent article, the superabsorbent material located between the two sheets in the absorbent zone swells by the absorption of moisture in the excrement and extends in the longitudinal direction from the opening, facing the wearer's crotch region. Spaces formed in a portion of the layer are formed between the non-absorbent region and the upper absorbent layer where no superabsorbent material is present, and between the non-absorbent region and the lower absorbent layer. In the absorbent article, through the space, the moisture of the second excretion and thereafter can quickly spread over a wide area along the longitudinal direction of the absorbent part, and the moisture of the excrement can be absorbed in the wide area of the absorbent part. As a result, it is possible to maintain high absorption capacity in multiple excretion in absorbent products.

Paper tissue with high bulk and low lint

A tissue paper product is provided having at least one ultra-low density ply having a highly porous, open-celled structure and that comprises cellulosic fibers, a water insoluble binder and a foaming surfactant. The cellulosic fiber comprises greater than 50% by weight of the ply and are bonded to one another by hydrogen bonding. Further, the ply has a density less than about 0.04 g/cc and yet still provides low lint and high strength properties with the use of minimal binder. The ultra-low density ply may comprise or be included in sheets forming a stack of dispensable wipers or may be employed as or part of an absorbent core or liquid distribution layer of a personal care absorbent personal care product such as a diaper or feminine pad.

Disposable absorbent article

A disposable absorbent undergarment is disclosed. It includes an absorbent assembly comprising a core formed of a synthetic tow or of synthetic nonwoven layers and having first section comprising a slow acting but high absorption capacity SAP and a second section comprising a fast acting but lower absorption capacity SAP, all of which is wrapped in a wrapper to hold the SAP in place. The absorbent assembly may be quilted and corrugated. The undergarment also includes releasably securable fasteners to enable it to be readily removed and a suspension system to ensure that the garment fits properly and doesn't leak even when holding a large amount of exudate. Odor removal/masking and treatment features may be provided. It addition the undergarment may include a wetness indicator.

Excellent Liquid Spreading Absorbent Pad

The present invention relates to an absorbent pad with excellent liquid diffusion functions. To this end, the absorbent pad comprises: a back sheet; a liquid absorbent layer: an absorption dispersion layer; a high density thermally bonded non-woven fabric layer; and a top sheet, which are laminated in order. The high density thermally bonded non-woven fabric layer is composed of a multi-lobal thermally bonded composite fiber having a release ratio of 1.3 to 3.5. The core portion of the composite fiber comprises a polyester resin or a polypropylene resin, and the sheath portion comprises a sheath-core type polyolefin-based resin having a melting point lower than the polyester-based resin by at least 20 deg. C.

Absorbent cores having material free areas

An absorbent core for use in an absorbent article is provided and comprises a core wrap enclosing an absorbent material, the absorbent material comprising superabsorbent polymer particles. The superabsorbent polymer particles represent less than 85% by weight based on the total weight of the absorbent material. The core wrap comprises a top side and a bottom side, the absorbent core comprises one or more area(s) substantially free of absorbent material through which the top side of the core wrap is attached to the bottom side of the core wrap, so that when the absorbent material swells the core wrap forms one or more channel(s) along the area(s) substantially free of absorbent material.
