Abstract (en)

[origin: WO9945878A1] The present invention relates to absorbent structures for use in absorbent articles, comprising a first region for acquisition/distribution of fluid and a second region for storage of fluid. The first region comprises materials, which may have a relatively high capillary desorption pressure, as the second region comprises materials or members exhibiting a sufficiently high capillary absorption pressure so as to still efficiently drain the first region. Thus, the first region comprises material having a cumulative flux of more than 0.075 g/cm<2>/sec at 12.4 cm heights, and/or a wicking time of less than 120 seconds at this height, and second region comprises material which satisfies at least one of following requirements: (a) an absorption capacity of at least 15 g/g at 35 cm in the capsorption test; and/or (b) an absorption capacity of at least 15 g/g at 0 cm in the capsorption test and an absorption efficiency of at least 55 % at 40 cm, and/or (c) a Capillary Sorption Absorption height at 50 % of its capacity at 0 cm absorption height (CSAH 50) of at least 35 cm in the capsorption test.
