Abstract
Abstract A laminate with improved aesthetic attributes is disclosed. The laminate comprises an air laid web of cellulosic fibers containing a pattern of highly compacted spot-bonded areas and fluffly mound regions of substantially unbonded fibers disposed between the bonded areas. The cellulosic web is united to a network of reinforcing elements, such as a scrim, drafted fiber web, or continuous filament web, with a layer of open patterned adhesive.
