ABSORBENT STRUCTURES COMPRISING FLUID STORAGE MEMBERS WITH IMPROVED ABILITY TO DEWATER DISTRIBUTION MEMBERS |
摘要 |
The present invention is an absorbent structure to be used in absorbent articles, having at least a first region for acquisition/distribution of fluid and a second region for storage of fluid. The first region can contain materials which have a relatively high capillary desorption pressure, as the materials in the second region exhibit a sufficiently high capillary absorption pressure so as to still efficiently drain the first region. The first region material has a Capillary Sorption Desorption Height (CSDH 90) of more than 40 cm and the second region material satisfies at least one of following requirements: (a) an absorption capacity of at least 15 g/g at 35 cm in the capsorption test; (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; (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.
