Abstract
An improved cloth-like base web is disclosed. In particular, the base web of the present invention has a cloth-like look and feel and has improved absorbency. The base web is made by first hydroneedling a web containing pulp and/or staple fibers. A bonding material is then applied to at least one side of the web and the web is creped on at least one side. By combining a hydroneedling operation with a creping operation, a base web is produced that is strong, stretchable, very soft and absorbent.
