Abstract: An air-laid unitary absorbent layer composed of crosslinked cellulosic fibers and a binder is disclosed. In a preferred embodiment, the binder is a bicomponent binding fiber. In combination with one or more other layers in an absorbent article, the unitary absorbent layer can rapidly acquire, distribute, temporarily store, and then release the acquired liquid to other liquid retention layers. A method for forming the unitary absorbent layer is also disclosed.

Abstract: A 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 serves as a temporary storage stratum. Methods for forming the unitary stratified composite are also disclosed.

Abstract: 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 (202, 204) to form a web and depositing or injecting absorbent material into the web across its width to provide a web (126) 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 wet-laid method and in another embodiment, the method is a foam-forming method. Preferably, the methods are twin-wire forming methods.
