A novel absorbent structure is disclosed in which an initially flat, dense structure becomes a three-dimensional, high bulk, channeled structure upon wetting. The structure offers unusually high directionality in fluid transport to improve the distribution of fluid in longitudinal articles. The self-bulking of the wetted article can also lead to improved fit in articles such as diapers and in general increases the void volume of the wetted article for high absorbent capacity.

[ We claim:] [1.] An absorbent article comprising: a liquid impervious backsheet; a liquid pervious topsheet; an absorbent core positioned between the topsheet and the backsheet; and a multifunctional transfer layer positioned between the absorbent core and the topsheet, said multifunctional transfer layer comprising a stability layer and an expansion layer heterogeneously attached to said stability layer at a discrete number of attachment regions, wherein, upon wetting, said expansion layer expands laterally in at least one direction substantially more than said stability layer, such that the wetted expansion layer puckers to form a plurality of pockets between the expansion layer and stability layer.
