Abstract:
1. An absorbent core for an absorbent article intended for absorption of menses or blood or vaginal discharges, the core comprising: a perimeter; a substrate layer including a substrate layer first surface and a substrate layer second surface; the absorbent core further including a non uniform layer of absorbent polymer material; the non uniform layer of absorbent polymer material including a non uniform layer of absorbent polymer material first surface and a non uniform layer of absorbent polymer material second surface; the absorbent core further including a layer of a thermoplastic material; the layer of thermoplastic material including a layer of thermoplastic material first surface and a layer of thermoplastic material second surface; the absorbent core further including a cover layer including a cover layer first surface and a cover layer second surface wherein the non uniform layer of absorbent polymer material second surface is in at least partial contact with the substrate layer first surface, wherein portions of the layer of thermoplastic material second surface are in direct contact with the substrate layer first surface within the perimeter and portions of the layer of thermoplastic material second surface are in direct contact with the non uniform layer of absorbent polymer material first surface, and wherein the cover layer second surface is in direct contact with the layer of thermoplastic material first surface; and the substrate layer and the cover layer each including a fibrous web of fibres substantially randomly oriented with respect to an X-Y plane, wherein the substrate layer or the cover layer comprise a plurality of discrete regions of fibre reorientation, comprising a plurality of fibres having portions reoriented in a direction substantially orthogonal to the X-Y plane.
