摘要：
An absorbent article having an ultimate fluid storage region and a fluid distribution region, positioned between the ultimate storage region and the garment oriented surface of the article, in fluid communication with the ultimate fluid storage region, the ultimate fluid storage region includes a material which has: (1) a Capillary Sorption Desorption Capacity at 100 cm (CSDC 100) of at least 10 g/g; (2) a Capillary Sorption Desorption Capacity at 0 cm (CSDC 0) higher than the CSDC 100; (3) a Loosely Bound Liquid Capacity (LBLC); and (4) a Capillary Sorption Desorption Release Height when 50% of the LBLC are released (CSDRH 50) less than 60 cm. Further, the liquid distribution layer material has a Capillary Sorption Absorption Height at 30% of its maximum capacity (CSAH 30) of at least 35 cm. Disuibution material can be foam materials, particularly those derived from high internal phase water-in-oil emulsions.
