An unitary stratified composite composed of a first stratum and a second stratum integrally connected by a transition zone is disclosed. The first stratum serves as a liquid acquisition stratum that rapidly acquires and then transfers liquid to the second stratum. The second stratum serves to withdraw liquid from the first stratum and further severs as a temporary storage stratum. Methods for forming the unitary stratified composite are also disclosed.

Methods for forming an absorbent fibrous composite containing absorbent material dispersed in bands through the composite and along the composite's length are disclosed. The methods generally include depositing a fibrous slurry on a foraminous support to form a web and depositing or injecting absorbent material into the web across its width to provide a web having absorbent material in bands along the composite's length. Drying the web provides a fluted absorbent composite. In one embodiment, the method is a wetlaid method and in another embodiment, the method is a foam-forming method. Preferably, the methods are twin-wire forming methods.

A unitary absorbent composite having a plurality of strata is disclosed. In the composite, adjacent strata are separated by a transition zone integrally connecting the strata. Each stratum includes fibers and a binder, and the transition zone includes fibers from adjacent strata. Method for forming the unitary composite are also disclosed.
