ABSTRACT:
A multi-ply absorbent wiping product having a relatively inextensible center ply bonded to highly extensible outer plies to provide superior wet bulk caliper and impression, wet strength and absorption characteristics. The central ply is comprised of wet strength, cellulosic tissue paper having less than about 10 percent stretch. Both sides of the central ply are imprinted with a suitable polymer resin in a regulated pattern covering between about 15 and about 55 percent of the total surface on each side of the central ply. An outer ply of wet strength, highly extensible, creped cellulosic tissue paper is adhered to each of the opposite surfaces of the central ply by feeding the layers between the nip of a pair of synchronously driven, hard-surfaced embossing rolls having a mating pattern of embossments thereon.
