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 the acquisition layer and the absorbent core, wherein the dryness layer laminate comprises:
• a) a carrier substrate having first and second tissue layers, and
• b) a matrix of superabsorbent particles and adhesive filaments,
• wherein the superabsorbent particles are stabilized between the first and second tissue layers of the carrier substrate by the adhesive filaments, wherein the first and second tissue layers of the carrier substrate each have a basis weight of no more than 20 grams per square meter, wherein the adhesive filaments of the dryness layer laminate comprising no more than 4 weight percent of the superabsorbent particles of the dryness layer laminate, wherein the superabsorbent particles of the dryness layer laminate have a basis weight between about 40 and about 130 grams per square meter, wherein a coefficient of variation (COV) of the basis weight of the superabsorbent particles throughout the dryness layer laminate is between about 5% and about 25%, so that the dryness layer laminate cooperates with the absorbent core to permit passage of liquid through the dryness layer laminate for retention of the liquid by the absorbent core, and
• wherein the superabsorbent particles in the dryness layer laminate are configured to enhance surface dryness of the absorbent structure.

An absorbent core system, comprising:

• a. an absorbent core;
• and
• b. a dryness layer laminate that is comprised of:
• i. first and second layers of tissue substrate, each of the first and second layers of tissue substrate comprised of cellulosic fibers,
• ii. a matrix comprising superabsorbent polymer particles and hot melt adhesive fibers stabilized between the first and second layers of tissue substrate,
• wherein the superabsorbent polymer particles of the dryness layer laminate have a basis weight of between about 40 grams per square meter and about 130 grams per square meter, and wherein a coefficient of variation (COV) of the basis weight of the superabsorbent particles throughout the dryness layer laminate is between about 10% and about 25% so that the dryness layer laminate cooperates with the absorbent core to permit passage of liquid through the dryness layer laminate for retention of the liquid in the absorbent core.

An absorbent core system, comprising:

• an absorbent core comprising upper and lower layers, each of the upper and lower layers of the absorbent core comprising a blend of wood pulp fibers and superabsorbent polymer, wherein the superabsorbent polymer in the upper layer of the absorbent core comprises about 35 weight percent of the blend of wood pulp fibers and superabsorbent polymer in the upper layer, and exhibits a centrifuge retention capacity of less than 30 grams/gram, wherein the superabsorbent polymer in the lower layer of the absorbent core comprises about 9 weight percent of the blend of wood pulp fibers and superabsorbent polymer in the lower layer, and exhibits a centrifuge retention capacity of at least 40 grams/gram;
• and
• a dryness layer laminate overlying the absorbent core, the dryness layer laminate comprising a substrate, filamentary adhesive, and superabsorbent polymer particles stabilized on the substrate by the filamentary adhesive, wherein the superabsorbent polymer particles of the dryness layer laminate has a basis weight between about 40 and about 130 grams per square meter, wherein a coefficient of variation (COV) of the basis weight of the superabsorbent particles throughout the dryness layer laminate being between about 5% and about 25% so that the dryness layer laminate cooperates with the absorbent core to permit passage of liquid through the dryness layer laminate for retention of the liquid by the absorbent core, and
• wherein the absorbent core system is devoid of an acquisition layer positioned above the dryness layer laminate.
