1. An absorbent core for an absorbent article, said core having a wearer facing surface and a garment facing surface, said core comprising a fibrous, layered structure of at least two layers, comprising:
a first layer having an overall basis weight of from 30 g/square meter to about 60 grams/square meter, the first layer comprising cellulose fibers, synthetic fibers and a latex, wherein the synthetic fibers are present in an amount of between about 7 percent to about 12 percent by weight of the first layer and the latex is present in an amount of less than about 10 percent by weight of the first layer, and wherein the first layer is substantially free of absorbent gelling materials; a second layer comprising fibers and an absorbent gelling material, said second layer being substantially free of cellulose fibers, the absorbent gelling material being present in an amount of about 70 percent to about 85 percent by dry weight of the second layer, and wherein said second layer comprises bicomponent synthetic fibers; said core comprising less than about 70% cellulose fibers based on the dry weight of said core; and said core comprising less than about 70% absorbent gelling materials based on the dry weight of said core, wherein the absorbent gelling materials comprise uncrosslinked polyacrylate.
