Abstract: A multi-layered web is disclosed that is resilient and/or elastic in the Z-direction. Thus, when the web is compressed, the web assumes a compacted state and then expands to an expanded state when the compressive forces are removed. In one embodiment, the multi-layered web includes a middle layer made from a resilient blend of fibers positioned inbetween two outer layers. The middle layer, for instance, can contain elastomeric fibers, three-dimensional fibers, and/or debonded fibers.

Abstract: A system comprising a pulper configured to (i) accept surfactant, a liquid and fiber stock and (ii) generate a foam that suspends the fiber stock, wherein the foam has a half-life; a headbox configured to receive the foam-suspended fiber stock from the pulper and displace the foam-suspended fiber stock onto a forming wire, wherein a time it takes the foam-suspended fiber stock to move from the pulper to the headbox is less than the half-life; and a foam return device that removes at least some of the foam from the forming wire and returns the at least some of the foam to the pulper.

Abstract: A process for foam forming webs is disclosed. The foam formed webs can be used as wiping products, such as industrial wipers, food service wipers, and the like. The web contains a mixture of cellulosic fibers and longer, strength building fibers. The web is foam formed and then subjected to one or more hydroentangling steps. After hydroentangling, the web is dried in a non-compressive manner.
