Abstract
Official abstract text for this publication.
Absorbent members, especially bulked absorbent members, and methods of making the same are disclosed. The absorbent member may be in the form of a unitary absorbent fibrous layer comprising at least some cellulose fibers. The unitary absorbent fibrous layer is at least partially stratified through its thickness. The absorbent member may also have a plurality of discrete deformations, such as depressions and/or apertures in its surfaces. The method involves subjecting a precursor web to at least one cycle (or pass) through a mechanical deformation process. The mechanical deformation process utilizes a first forming member and a second forming member that form a nip therebetween through which the precursor web is passed. The first and second forming members are moving at different speeds relative to each other when they come together to form the nip.
First claim
Opening claim text (preview).
What is claimed is: 1. A method for making an absorbent member, said method comprising: a) providing a precursor web material, said precursor web material comprising a wetlaid cellulosic fibrous structure, said precursor web material having a first surface and a second surface; b) providing a pair of forming members forming a nip therebetween, said forming members comprising: a first forming member having a surface comprising a plurality of first forming elements, wherein said…
