    摘要： An absorbent core comprising: a front portion; a back portion; a middle portion position between the front portion and the back portion; and a longitudinal axis extending along a length of said core and crossing said front, middle and back portions, the absorbent core having a width extending perpendicular to said length and a perimeter comprising at least two opposing ends and at least two opposing sides positioned between said ends, said core comprising an absorbent material sandwiched between upper and lower layers of said core wherein the absorbent core comprises at least one interconnected channel substantially free of absorbent material and with at least portions thereof extending along both the length and the width of said core arranged to form an open end proximal to the front portion and a closed end proximal to the back portion and wherein said channel is formed by mechanically bonding said upper layer directly to said lower layer at a plurality of distinct bonding sites, wherein each channel portion comprises no more than two consecutive bonding sites taken along a channel width axis.

    摘要： The present invention relates to absorbent cores for use in absorbent articles, preferably of the disposable personal hygiene type. It discloses absorbent cores comprising a foam layer incorporating a nonwoven fabric and having a top surface and a bottom surface, said foam layer top surface comprising one or more indented compressed portions and one or more raised non-compressed portions. The foam layer has openings extending through the foam and the nonwoven fabric. The absorbent core further comprises, joined to the bottom surface of the foam layer, a nonwoven comprising superabsorbent polymers. Absorbent cores of the present invention provide a fast acquisition of body exudates and a good liquid retention capacity. This is further achieved in a simple and cost-effective way without complex and considerable foam formulation and processing requirements.
