    摘要： One aspect of the present invention relates to an absorbent composite suitable for use in a disposable absorbent garment. The absorbent composite includes means for containing a superabsorbent material and a superabsorbent material contained by said containment means. The superabsorbent material has a Pressure Absorbency Index of at least 100 and a 16-hour extractable level of less than about 13 weight percent; a Pressure Absorbency Index of at least 100 and a Vortex Time of less than about 45 seconds; or a Pressure Absorbency Index of at least about 110. The superabsorbent material is present in said containment means in an amount of from about 30 to about 100 weight percent based on total weight of the containment means and the superabsorbent material. In a second aspect, the present invention relates to a disposable absorbent garment including an outer cover, a body-side liner, and an absorbent composite such as that described above.

    摘要： A distinctive absorbent article includes a backsheet layer, and an absorbent structure superposed on the backsheet layer. The absorbent structure includes particles of high absorbency material, and a liquid permeable topsheet layer is superposed on the absorbent structure to sandwich the absorbent structure between the topsheet layer and the backsheet layer. A fibrous face sheet layer is incorporated in the article for restraining a movement of the high absorbency material from selected regions of the absorbent structure. The face sheet layer has a Frazier Porosity value of at least about 150 cubic feet per minute per square foot of surface area (cfm/ft.sup.2), and has not more than about 100 pores (per 31.37 cm.sup.2 of surface area) with a pore size greater than about 300 micrometers.

    摘要： A polymeric composition specifically adapted to absorb blood and other proteinaceous fluids and having repeating units, said polymeric composition comprising pendant neutralized carboxyl groups (salts) and pendant carboxyl groups. The polymeric composition is characterized in that the ratio of pendant neutralized carboxyl groups to pendant carboxyl groups is within the range of from about 1:9 to about 9:11, at least about 20 mole percent of the repeating units comprise a pendant neutralized carboxyl group or a pendant carboxyl group, and at least about 50 percent of the pendant neutralized carboxyl groups have been neutralized with a potassium or lithium base.
