Absorbent article with channels and method for manufacturing thereof

An absorbent article comprising a liquid pervious topsheet, a liquid impervious backsheet, and an absorbent core comprising an absorbent material between a top core wrap sheet and a back core wrap sheet, said absorbent core being positioned in between said topsheet and said backsheet;

• said absorbent material comprising at least one of cellulosic fluff pulp and superabsorbent particles;
• said absorbent core having a first and second longitudinal edge and a front and rear transverse edge, said absorbent core having a longitudinal center line dividing the absorbent core in a first longitudinal portion and a second longitudinal portion on either side of the longitudinal center line, said absorbent core having a transverse crotch line dividing the absorbent core in a front portion between the transverse crotch line and the front transverse edge and a rear portion between the transverse crotch line and the rear transverse edge;
• said absorbent core being provided with a first and second elongate attachment zone where the top core wrap sheet is welded to the back core wrap sheet in accordance with a sealing pattern of discrete elements;
• said first elongate attachment zone crossing said longitudinal center line in a first crossing point;
• and said second elongate attachment zone crossing said longitudinal center line in said first crossing point;
• said first and second attachment zone together forming at least one of a substantially V-shaped zone and a substantially U-shaped zone;
• said first and second attachment zone each extending, seen in a transverse direction of the absorbent core, over the transverse distance which is at least 3 mm;
• and
• said first and second attachment zones being permanent attachment zones which remain attached when wetted.

• said absorbent core being provided with a plurality of attachment zones where the top core wrap sheet is attached to the back core wrap sheet;
• said plurality of attachment zones comprising:
• in said rear portion, a first attachment zone, a second attachment zone and a V-shaped rear interconnecting attachment zone connecting said first and second attachment zone, so as to form together a substantially V-shaped rear attachment zone;
• said first and second attachment zone extending from said rear interconnecting attachment zone in the direction of the rear transverse edge;
• in said front portion, a third attachment zone, a fourth attachment zone, and a V-shaped interconnecting attachment zone connecting said third and fourth attachment zone, so as to form together a substantially V-shaped front attachment zone;
• said first and second attachment zone extending from said front interconnecting attachment zone in the direction of the front transverse edge;
• and
• a central attachment zone connecting said front interconnecting attachment zone with said rear interconnecting attachment zone.
