Absorbent product for personal use

An absorbent product consisting essentially of an absorbent core including a given amount of a super absorbent polymer, said core consisting essentially of a water permeable cover sheet,

• an absorbent fluff layer having first and second major surfaces, said first surface being positioned adjacent to said cover sheet,
• an absorbent laminate layer for absorbing and retaining liquid, said absorbent laminate layer
• (a) being positioned between said fluff layer and said cover sheet,
• (b) consisting essentially of aperture free tissue and a first portion of super absorbent polymer that is subject to gel blocking when wet, and is present in an amount sufficiently great that gel blocking occurs when the laminate is wet, said first portion of super absorbent polymer being less than the given amount, and being secured to and supported on said tissue, and
• (c) being positioned so that it is adjacent to and covers at least a central portion of the first major surface of said fluff layer,
• a second portion of super absorbent polymer distributed in said fluff layer, adjacent to the first major surface thereof,
• wherein said fluff layer and said absorbent laminate layer are connected to each other by a plurality of channel regions consisting of compressed, physically integrated portions of said fluff layer and of said absorbent laminate layer, the channel regions having a given density and, between the channel regions, discrete regions composed of portions of said fluff layer and of said absorbent laminate layer, and having a density less than the given density, said channel regions having been formed by pressing absorbent laminate into a moistened surface of said fluff layer, and the absorbent core has improved absorbency as a consequence of said channel regions, and is operable to absorb, through said cover sheet, multiple wettings with simulated urine in quantities which would cause gel blocking in the absence of said channel regions, and
• a water impervious backing sheet positioned adjacent the second surface of said absorbent fluff layer.

An absorbent core including a super absorbent polymer, said core consisting essentially of

• a water permeable cover sheet,
• an absorbent fluff layer having first and second major surfaces, the first surface being positioned adjacent to said cover sheet,
• a layer of tissue disposed between the first major face of said fluff layer and said cover sheet, and
• super absorbent polymer powder distributed in said fluff layer, adjacent to the first major surface,
• wherein said fluff and tissue layers are connected to each other by a plurality of channel regions consisting of compressed, physically integrated portions of the fluff and tissue layers having a given density and, between the channel regions, discrete regions of portions of said fluff and tissue layers having a density less than the given density, said channel regions having been formed by pressing the tissue layer into a moistened surface of the fluff layer, and the absorbent core has improved absorbency as a consequence of said channel regions, and is operable to absorb, through said cover sheet, multiple wettings with simulated urine in quantities which would cause gel blocking in the absence of said channel regions.
