Claim 14:
15. An absorbent article for personal hygiene comprising:
a liquid permeable topsheet;
a liquid impermeable backsheet;
an absorbent core disposed between the topsheet and the backsheet; and
an acquisition/distribution layer disposed between the absorbent core and the topsheet;
wherein the absorbent core comprises:
a core wrap enclosing an absorbent material comprising a combination of superabsorbent polymer particles and airfelt, the core wrap comprising a top side and a bottom side;
a pair of areas substantially free of absorbent material disposed symmetrically relative to a longitudinal axis through which the top side of the core wrap is attached to the bottom side of the core wrap, so that when the absorbent material swells the core wrap forms a pair of channels along the areas substantially free of absorbent material and corresponding ditches;
wherein the superabsorbent polymer particles have a time to reach an uptake of 20 g/g (T20) of less than 240 s, as measured according to the K(t) test method; and
wherein the attachment between the top side core wrap and the bottom side core wrap is achieved through adhesive bonding, pressure bonding, ultrasonic bonding, heat bonding, or combinations thereof.
