Abstract
The present invention relates generally to an absorbent multi-layer material or to a core for an absorbent article, and more particularly to an absorbent multi-layer material or to a core comprising a central absorbent layer positioned between an upper layer and a lower layer, wherein at least of the upper and/or lower layer(s) has a vertical wicking index of greater than about 6 cm after 19 minutes and/or greater than about 3 cm after 1 minute. Such a multi-layer material or multi-layer core provides improved strength, absorption and rewetting properties. An absorbent article that contains such a multi-layer material or core provides improved ability to absorb and retain fluids and consequently, prevents excessive rewetting and leakage.
