When the first intake layer includes a resilient coform material, the retention layer includes one of a high-density, hydrogen-bonded, fluff/superabsorbent polymer material, a spunlace material, a superabsorbent polymer/adhesive composite material, and a foam material. The absorbent composite can further include a distribution layer disposed between the topsheet and the backsheet, the distribution layer including one of a meltblown microfiber material, a spunlace material, and a foam material. ## Claims ### Claim 1 An absorbent composite disposed in an absorbent article between a topsheet and a backsheet, the absorbent composite comprising: a first intake layer disposed between the topsheet and the backsheet; and a retention layer disposed between the topsheet and the backsheet, wherein one of the first intake layer and the retention layer includes a resilient coform material. ### Claim 2 (depends on 1) The absorbent composite of claim 1, wherein the first intake layer includes a resilient coform material, and wherein the retention layer includes one of a coform material, a resilient coform material, a bonded-carded web (BCW) material, and an airlaid material. ### Claim 3 (depends on 2) The absorbent composite of claim 2, wherein the retention layer further includes superabsorbent material. ### Claim 4 (depends on 2) The absorbent composite of claim 2, wherein the retention layer further includes fluff pulp. ### Claim 5 (depends on 1) The absorbent composite of claim 1, wherein the first intake layer includes a resilient coform material, and wherein the retention layer includes one of a high-density, hydrogen-bonded, fluff/superabsorbent polymer material, a spunlace material, a superabsorbent polymer/adhesive composite material, and a foam material. ### Claim 6 (depends on 5) The absorbent composite of claim 5, wherein the retention layer further includes fluff pulp. ### Claim 7 (depends on 1) The absorbent composite of claim 1, wherein the retention layer includes a resilient coform material, and wherein the first intake layer includes one of a coform material, a resilient coform material, an airlaid material, a bonded-carded web (BCW) material, and a foam material. ### Claim 8 (depends on 7) The absorbent composite of claim 7, wherein the first intake layer further includes fluff pulp. ### Claim 9 (depends on 7) The absorbent composite of claim 7, wherein the resilient coform material in the retention layer includes superabsorbent material. ### Claim 10 (depends on 1) The absorbent composite of claim 1, further comprising a distribution layer disposed between the topsheet and the backsheet, the distribution layer including one of a meltblown microfiber material, a spunlace material, and a foam material. ### Claim 11 (depends on 1) The absorbent composite of claim 1, wherein the first intake layer includes a resilient coform material, and wherein the retention layer includes a high-density, hydrogen-bonded, fluff/superabsorbent polymer material. ### Claim 12 (depends on 1) The absorbent composite of claim 1, wherein the first intake layer includes a resilient coform material, and wherein the retention layer includes an airlaid material. ### Claim 13 (depends on 1) The absorbent composite of claim 1, wherein both the first intake layer and the retention layer include a resilient coform material. ### Claim 14 (depends on 13) The absorbent composite of claim 13, wherein the retention layer further includes superabsorbent material. ### Claim 15 (depends on 1) The absorbent composite of claim 1, further comprising a second intake layer disposed generally in parallel with the first intake layer, the second intake layer including one of an airlaid material, a bonded-carded web (BCW) material, a resilient coform material, and a foam material. ### Claim 16 (depends on 1) The absorbent composite of claim 1, wherein the intake layer is between the topsheet and the retention layer, and wherein the retention layer is between the backsheet and the intake layer. ### Claim 17 An absorbent composite disposed in an absorbent article between a topsheet and a backsheet, the absorbent composite comprising: a first intake layer including one of a coform material, a resilient coform material, an airlaid material, a bonded-carded web (BCW) material, and a foam material; and a retention layer disposed between the topsheet and the backsheet, the retention layer including one of a coform material, a resilient coform material, an airlaid material, a high-density, hydrogen-bonded, fluff/superabsorbent polymer material, a spunlace material, a superabsorbent polymer/adhesive composite material, and a foam material, wherein one of the first intake layer and the retention layer includes a resilient coform material. ### Claim 18 An absorbent composite adapted to be disposed in an absorbent article between a topsheet and a backsheet, the absorbent composite comprising: a first intake layer including a resilient coform material; and a retention layer disposed between the topsheet and the backsheet, the retention layer including one of a coform material, a resilient coform material, an airlaid material, a high-density, hydrogen-bonded, fluff/superabsorbent polymer material, a spunlace material, a superabsorbent polymer/adhesive composite material, and a foam material. ### Claim 19 An absorbent personal care article having a topsheet and a backsheet, the article comprising: an absorbent composite disposed between the topsheet and the backsheet, the absorbent composite including a first intake layer including a resilient coform material, and a retention layer disposed between the topsheet and the backsheet, the retention layer including one of a coform material, a resilient coform material, an airlaid material, a high-density, hydrogen-bonded, fluff/superabsorbent polymer material, a spunlace material, a superabsorbent polymer/adhesive composite material, and a foam material. ### Claim 20 A method for making absorbent personal care article having an absorbent composite, the method comprising: merging a stream of an absorbent material with a stream of meltblown fibers to form a composite stream; collecting the composite stream on a forming surface to form a resilient coform nonwoven web; and combining the resilient coform nonwoven web with a topsheet and a backsheet. ### Claim 21 An absorbent composite adapted for use in an absorbent article having a topsheet and a backsheet, the absorbent composite comprising: an intake layer including a foam material disposed between the topsheet and the backsheet, the intake layer having a plurality of holes therethrough; and a retention layer disposed between the topsheet and the backsheet, wherein the retention layer includes a resilient coform material. ### Claim 22 (depends on 21) The absorbent composite of claim 21, wherein the retention layer has a plurality of holes therethrough.
