Abstract
A substantially planar absorbent core (28) extending in a transversal direction (x) and a longitudinal direction (y), and comprising a core wrap (16, 16′) enclosing an absorbent material (60) substantially free of cellulose fibers, the absorbent material forming a pattern of discrete absorbent material areas. The pattern comprises transversally-orientated areas (752) and longitudinally-orientated areas (754). The absorbent core may further comprise at least two longitudinally-orientated channel-forming areas (26).
Claims19
A substantially planar absorbent core extending in a transversal direction and a longitudinal direction, having:
- a longitudinal axis, a front region, a middle region and a back region, these three regions being of equal length in the longitudinal direction as measured on the longitudinal axis, and
- a core wrap fully enclosing an absorbent material, the absorbent material forming a pattern of discrete absorbent material areas wherein some of the discrete absorbent material areas are separated by unbonded areas wherein a top side of the core wrap is unbonded to a bottom side of the core wrap, and other of the discrete absorbent material areas are separated by bonded areas wherein the top side of the core wrap is bonded to the bottom side of the core wrap, and wherein at least one unbonded area is adjacent to at least one bonded area.
An absorbent article comprising a topsheet, a backsheet and an absorbent core disposed between the topsheet and backsheet, wherein the absorbent core comprises:
- a core wrap enclosing an absorbent material, the absorbent material forming a pattern of discrete absorbent material areas wherein some of the discrete absorbent material areas are separated by unbonded areas wherein a top side of the core wrap is unbonded to a bottom side of the core wrap, and other of the discrete absorbent material areas are separated by bonded areas wherein the top side of the core wrap is bonded to the bottom side of the core wrap, and wherein at least one unbonded area is adjacent to at least one bonded area.
