Abstract
An absorbent article includes a topsheet, a backsheet and an absorbent core disposed between the topsheet and the backsheet. A sublayer is disposed between the topsheet and the absorbent core. The sublayer includes sides edges which extend past the side edges of the absorbent core and end edges which extend to the front and rear waist regions of the absorbent article. The side edges of the sublayer are secured to the backsheet in the area between the side edges of the absorbent core and the leg elastics. The attachment of the side edges of the absorbent core improves the liquid take-up by ensuring contact between the absorbent core and the sublayer even after the bond between the sublayer and the absorbent core may have failed. In addition, the attachment of the side edges to the backsheet ensures that the absorbent core maintains its shape even after it is saturated with liquid.
