Abstract

A high utility (strong in both dry and wet states, highly absorbent, abrasion resistant, thick, and soft) disposable wiper or towel that contains 85% or more recycled fibers and, in one construction, 100% recycled fibers. The recycled fibers are from post-consumer waste and/or post-industrial waste. The base sheet is produced in a wet-pressed, creped process and is post-treated using a DRC process. The final wiper or towel is a double re-creped, non-woven sheet having a first side and a second side. The non-woven sheet includes about 85% to about 90% by weight of cellulose fibers. The non-woven sheet includes at least about 10% to about 15% by weight of binder.
