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.
Absorbent structure comprising a first region and a second region in liquid communication with said first region characterized in that said first region comprises material having a Capillary Sorption Desorption Height (CSDH) 90 of more than 40 cm, and said second region comprises material which satisfies at least one of following requirements:
An absorbent structure according to any of the preceding claims, wherein said first region comprise fibrous material.
An absorbent structure according to any of the preceding claims, wherein said first region comprises foam material.
An absorbent structure according to any of the preceding claims, wherein said second region comprises a high surface area material.
An absorbent structure according to any of the preceding claims, where said second region comprises hydrogel forming materials.
Disposable absorbent articles comprising at least one absorbent structure according to any of the preceding claims.
Disposable absorbent article according to any of the preceding claims for being used as baby diaper, adult incontinence article, feminine hygiene article, training pant and the like.
Absorbent structure comprising a first region and a second region in liquid communication with said first region characterized in that said first region comprises material having a CSDH 80 of more than 35 cm and said second region comprises material which satisfies at least one of following requirements:
