Abstract
The present invention is directed to a nonwoven fabric made from a composite of nonwoven and pulp where the nonwoven has a high loft derived from a heat set three-dimensional relief structure and/or hydroengorged fiber structure. A nonwoven web is hydraulically treated to create a hydroengorged material having an increased loft. Alternatively a nonwoven web is treated to have a heat set three-dimensional relief structure. The treated web is then hydroentangled with pulp to form a cotendered nonwoven/pulp composite fabric.
