Abstract
Absorbent core for disposable absorbent articles, for example for the absorption of menses or blood.
Claims17
An absorbent core for an absorbent article, said core comprising a substrate layer having a basis weight from about 75 g/m2 to about 120 g/m2,
- said substrate layer comprising a first surface and a second surface,
- said absorbent core further comprising a layer of absorbent polymer material,
- said layer of absorbent polymer material comprising a first surface and a second surface,
- said absorbent core further comprising a layer of adhesive,
- said layer of adhesive comprising a first surface and a second surface,
- wherein said layer of absorbent polymer material is comprised between said layer of adhesive and said substrate layer,
- said second surface of said layer of absorbent polymer material is in contact with said first surface of said substrate layer,
- and said first surface of said layer of absorbent polymer material is in contact with said second surface of said layer of adhesive,
- wherein said substrate layer comprises a composite of at least a first layer and third layer of fibrous non-woven webs, said first layer and said third layer comprising synthetic fibers with an average fiber denier from about 1 to about 6.0, said composite further comprises a second layer comprising pulp, wherein said first layer is joined to a face of said second layer in a face to face relationship by bonding between the layers and said third layer is joined to a second face of said second layer in a face to face relationship by bonding between the layers, wherein said bonding comprises intertwining of the fibers between the layers.
