Disposable absorbent diapers are provided with improved comfort, fit and liquid transportation. The absorbent core of the disposable absorbent diapers comprises at least one absorbent structure comprising a substrate layer and an absorbent layer with channels. The channels are formed by bonding of the first substrate layer (16) to a second substrate layer through the channels so that the channels are at least partially maintained both in the dry state and in the wet state.Cette invention concerne des couches absorbantes jetables plus confortables, plus ajustées et plus absorbantes. Le noyau absorbant de ces couches comprend au moins une structure absorbante constituée d'une couche de substrat et d'une couche absorbante comportant des canaux.
