Abstract
The present invention is generally directed to base webs that are creped after a bonding material has been applied to at least one side of the web according to a predetermined pattern. The base web disclosed in the present application is made from at least three fibrous layers. The outer layers of the web contain synthetic staple fibers for increasing the tensile strength and abrasion resistant properties of the web. In one embodiment, the middle layer can further contain hardwood fibers, such as eucalyptus fibers, which improves the wipe dry properties of the web.
