  • Publication number: 20210212865
    Abstract: An absorbent article having a liquid-handling system includes a liquid permeable bodyside liner; a liquid impermeable outer cover; and an absorbent core disposed between the liner and the outer cover, wherein the absorbent core has a longitudinal direction, wherein the absorbent core includes a layer of a three-dimensionally patterned, wetlaid, cellulosic tissue nonwoven material, and wherein the layer includes longitudinal ridges and grooves. The absorbent core can include multiple layers of a three-dimensionally patterned, wetlaid, cellulosic tissue nonwoven material, wherein each layer of the multiple layers includes longitudinal ridges and grooves, and wherein the multiple layers are joined by lines of embossing, such lines of embossing extending in the longitudinal direction. Each layer of the multiple layers can include embossed longitudinal ridges and grooves.

  • Publication number: 20210007879
    Abstract: An absorbent article can have a topsheet layer, a liquid impermeable layer, and an absorbent core positioned between the topsheet layer and the liquid impermeable layer. The absorbent article can further include an exudate management layer in fluid communication with the topsheet layer. In various embodiments, the exudate management layer can be positioned on a body facing surface of the topsheet layer. In various embodiments, the exudate management layer can be positioned between the topsheet layer and the absorbent core. The exudate management layer has a first component which defines an opening for direct passage of body exudates into the absorbent core. The exudate management layer has a second component which at least partially overlaps the first component of the exudate management layer and further extends in the longitudinal direction of the absorbent article in a direction towards the posterior region of the absorbent article.

  • Patent number: 6979386
    Abstract: A tissue product containing a cellulosic fibrous material and less than about 10 wt. % of a superabsorbent material (e.g., fibers, particles, etc.) is provided. In some instances, the superabsorbent material can absorb between about 100 to about 350 grams of an aqueous solution per gram of superabsorbent material. In some embodiments, the superabsorbent material can be applied at the stock-preparation stage of a papermaking process, and can be provided in a dry or preswollen state.
