Fluid acquisition layer
A liquid acquisition material for use in an absorbent article. The liquid acquisition material having first fibers and second fibers. The first fibers are chemically cross-linked cellulose fibers and the second fibers are selected from the group consisting of: polyethylene, polypropylene, polyester, rayon, lyocell, and mixtures thereof. The liquid acquisition material has a total dry weight, the first fibers have a first dry weight, and the second fibers have a second dry weight. The first dry weight is from 30 to 95 percent of the total dry weight and the second dry weight is from 5 to 70 percent of the total dry weight.
1. A diaper comprising:
a liquid pervious topsheet;
a liquid impervious backsheet;
an acquisition system disposed between said liquid pervious topsheet and said liquid impervious backsheet; and
a storage layer disposed between said acquisition system and said liquid impervious backsheet, wherein said storage layer comprises an absorbent gelling material,
wherein the acquisition system comprises an upper acquisition layer and a lower acquisition layer, wherein said lower acquisition layer is disposed between said upper acquisition layer and said storage layer and wherein the lower acquisition layer comprises a liquid acquisition material, said liquid acquisition material comprising: first fibers and second fibers, wherein said first fibers are chemically cross-linked cellulose fibers and said second fibers being selected from the group consisting of: polyethylene, polypropylene, polyester, rayon, lyocell, and mixtures thereof, wherein said liquid acquisition material has a total dry weight, said first fibers have a first dry weight of from about 30 to about 90 percent of said total dry weight, and said second fibers have a second dry weight of from about 10 to about 20 percent of said total dry weight, and wherein said liquid acquisition material has a Medium Desorption Pressure value corresponding to a height between about 5 cm and about 20.5 cm.
