Disposable diaper having first and second absorbent structures and channels

A disposable diaper having a transverse and longitudinal dimension, the disposable diaper comprising a backsheet, a topsheet and an absorbent core disposed therebetween, wherein the absorbent core comprises a first absorbent structure comprising a first substrate layer, a first absorbent layer comprising absorbent polymer particles and cellulose, and a first adhesive layer in direct contact with the first absorbent layer, the first absorbent layer comprising:

• i. transverse and longitudinal dimensions;
• ii. a pair of opposing longitudinal edges extending in the longitudinal dimension;
• iii. a pair of opposing transversal edges extending in the transverse dimension;
• iv. front, crotch and back regions arranged sequentially in the longitudinal dimension;
• and
• v. two longitudinal portions delimited by a plane perpendicular to a central longitudinal axis of the first absorbent structure;
• wherein the first absorbent layer comprises at least two channels, each channel being substantially free of the absorbent polymer particles and cellulose and each channel extending through the thickness of the first absorbent layer in its longitudinal dimension, wherein each of the channels:
• a. has a width of from about 3 mm to about 15 mm;
• b. extends over at least about 15% of the longitudinal dimension of the first absorbent layer;
• c. is at least present in the crotch region or part thereof, and
• wherein the at least two channels comprise two adjacent channels, wherein the two adjacent channels are separated in the crotch region by a distance D of at least about 10 mm;
• and
• wherein the absorbent core further comprises an acquisition system, wherein said acquisition system at least partially fills in the two adjacent channels, and
• wherein the absorbent core comprises a second absorbent structure, the second absorbent structure comprising a second substrate layer, a second absorbent layer comprising absorbent polymer particles and cellulose and at least two channels, and a second adhesive layer in direct contact with the second absorbent layer;
• and
• wherein the first and second absorbent layers are mirror images of each other and are combined via direct contact of the first and second adhesive layers such that each channel of the second absorbent layer superposes a corresponding channel of the first absorbent layer to form a plurality of channels through the thickness of the absorbent core.
