Abstract
An absorbent core for disposable absorbent articles comprising absorbent material having a basis weight that varies across the absorbent core is provided.
Claims7
A method for making an absorbent core which comprises the steps of forming an absorbent structure by:
- (a) providing a substrate layer having a longitudinal dimension and a transverse dimension;
- (b) forming a profiled absorbent layer by depositing an absorbent material comprising absorbent polymer material on said substrate layer to create zones of different absorbent material basis weight in the longitudinal dimension and transverse dimension;
- (c) applying thermoplastic adhesive material on the absorbent layer to create zones of different thermoplastic adhesive material basis weight;
- (d) forming at least six low basis weight transverse segments and at least one reference segment, wherein:
- in the at least six low basis weight transverse segments, an average absorbent material basis weight and an average thermoplastic adhesive material basis weight of the absorbent layer are lower relative to an average absorbent material basis weight and an average thermoplastic adhesive material basis weight in the at least one reference segment.
