Absorbent pads comprising zones of differential absorbent capacity

摘要

An folded absorbent sanitary pad having a lower basis weight of superabsorbent polymer in correspondence with the folding lines which helps reducing the stiffness of the article caused by the folding lines.

主权项

1. A folded absorbent pad having, in its flattened unfolded configuration a central longitudinal axis and a central transversal axis said pad comprising:
a topsheet, a backsheet and an absorbent core disposed between said topsheet and backsheet, one or more folding lines wherein at least one of said folding lines is parallel to said central transversal axis and extends from a first side end to a second side end of the absorbent pad, said absorbent core comprising a storage layer said storage layer comprising superabsorbent particles and comprising, in correspondence with the one or more folding lines, one or more folding portions said folding portions being defined as portions of the storage layer overlapping said folding lines within the absorbent core and extending for from 3 to 20 mm on both sides of said folding lines along a direction perpendicular to said folding lines, wherein the folding portions abut non-folding portions on at least two edges, wherein in at least one of said folding portions the average basis weight of the SAP is at least 10 gsm lower than the average basis weight of superabsorbent polymers in the entire storage layer, and wherein the folding portion average basis weight is uniform throughout the folding portion.
