ABSORBENT CORES HAVING IMPROVED ACQUISITION CAPABILITY, AND ABSORBENT ARTICLES CONTAINING THEM

摘要

The invention relates to an absorbent core capable of absorbing discharged aqueous body fluids, said absorbent core comprising: (1) an upper fluid acquisition/distribution component capable of receiving aqueous fluids, the fluid acquisition/distribution components being positioned in the fluid discharge region of the absorbent core; (2) at least one upper fluid storage component positioned at least partially underneath and in fluid communication with the upper fluid acquisition/distribution component(s), the upper fluid storage component being capable of expanding in the z-direction when contacted with aqueous body fluids to form a fluid acquisition zone; (3) a fluid acquisition zone capable of receiving aqueous body fluids, the fluid acquisition zone being at least partially surrounded by said at least one upper fluid storage component(s); (4) a lower fluid acquisition/distribution component capable of acquiring and transporting aqueous body fluids being positioned at least partially underneath and in fluid communication with the upper fluid storage component(s); and (5) preferably, at least one lower fluid storage component positioned underneath the lower fluid acquisition/distribution component and in fluid communication therewith. The invention further relates to an absorbent article useful for absorbing discharged aqueous body fluids that comprises: A) a fluid pervious topsheet; B) a backsheet; and C) an absorbent core of the present invention.
