Absorbent structure with dryness layer

An absorbent structure comprising:

• an absorbent core;
• an acquisition layer;
• and
• a dryness layer laminate positioned in liquid-transferring relationship between said acquisition layer and said absorbent core,
• said dryness layer laminate comprising a carrier substrate including first and second tissue layer, and a matrix of superabsorbent particles and adhesive filaments, with said superabsorbent particles stabilized between said first and second tissue layers of said carrier substrate by said adhesive filaments,
• said first and second tissue layers of said carrier substrate each having a basis weight of no more than about 20 grams per square meter, and a Frazier porosity of at least about 120 ft3/min/ft2, and said adhesive filaments of said dryness layer laminate comprising no more than about 4 weight percent of the superabsorbent particles,
• said superabsorbent particles of dryness layer having a basis weight between about 40 and 130 grams per square meter, wherein a coefficient of variation (COV) of the basis weight of said superabsorbent particles in said dryness layer laminate is greater than about 5%,
• said dryness layer laminate cooperating with said absorbent core to permit passage of liquid through said dryness layer for retention of the liquid by the absorbent core, such that the dryness layer laminate retains an amount of liquid that is less than 60% of its Absorption Under Pressure capacity at 0.3 psi in the Anarewet acquisition test, said superabsorbent particles in said dryness layer laminate functioning to enhance surface dryness of the absorbent structure.

An absorbent core system, comprising:

• a. an absorbent core comprised of cellulosic fibers;
• b. at least one synthetic nonwoven layer;
• and
• c. a dryness layer laminate, disposed between said absorbent core and said synthetic nonwoven layer, comprised of:
• i. first and second layers of tissue substrate,
• ii. a mixture of superabsorbent polymer and hot melt adhesive fibers between said first and second tissue substrates, and
• iii. superabsorbent polymer particles having a basis weight of between about 40 grams per square meter and 130 grams per square meter, wherein said dryness layer laminate exhibits a basis weight COV between 10% and 25%,
• wherein the only cellulosic fiber disposed between the superabsorbent polymer particles in said dryness layer laminate and said synthetic nonwoven layer is that cellulosic fiber which comprises said first and second tissue substrates of said dryness layer laminate.

An absorbent core system, comprising:

• an absorbent core comprising upper and lower layers, each of said upper and lower layers comprising a blend of wood pulp fibers and superabsorbent polymer,
• said superabsorbent polymer in said upper layer comprising about 35 weight percent of said blend of wood pulp fibers and superabsorbent polymer in said upper layer, and exhibiting a centrifuge retention capacity of less than about 30 grams/gram,
• said superabsorbent polymer in said lower layer comprising about 9 weight percent of said blend of wood pulp fibers and superabsorbent polymer in said lower layer, and exhibiting a centrifuge retention capacity of at least about 40 grams/gram;
• and
• a dryness layer comprising a substrate, filamentary adhesive, and superabsorbent polymer stabilized on said substrate by said filamentary adhesive, said absorbent core system exhibiting a Fourth Dose Rewet value less than about 1 gram, and a Fourth Dose Plate Wetness of less than about 0.1 grams.
