Abstract
An absorbent article comprises a topsheet on the wearer-facing side, a backsheet on the garment-facing side, and an absorbent core positioned between the topsheet and the backsheet. The absorbent core comprises an absorbent material comprising a superabsorbent polymer, a core wrap enclosing the absorbent material, and a first channel disposed on one side of the longitudinal axis and a second channel disposed on the other side of the longitudinal axis.
Claims17
A process for gluing an absorbent core to a backsheet, the process comprising the steps of:
- providing an absorbent core having a longitudinal axis and comprising:
- an absorbent material comprising a superabsorbent polymer;
- a core wrap enclosing the absorbent material;
- a first channel disposed on one side of the longitudinal axis and a second channel disposed on the other side of the longitudinal axis, wherein the first channel and the second channel are substantially free of the absorbent material;
- applying a first glue on the backsheet or the absorbent core, on a first glue application area according to a first glue application pattern;
- applying a second glue on the backsheet or the absorbent core, on a second glue application area according to a second glue application pattern;
- and
- bringing the backsheet and the absorbent core in contact so that they are attached by the first glue and second glue.
