Abstract:
A papermaking fabric comprising an upper porous nonwoven member and an underlying porous member supporting said upper porous member wherein:(1) the upper porous nonwoven member comprises a material selected from the group consisting of a fibrous nonwoven web, a scrim, an extruded polymeric network, an open-cell foam and an extruded polymeric foam, having a Low Pressure Compressive Compliance greater than 0.05, a High Pressure Compressive Compliance greater than 0.05, and an Upper Surface Depth of at least 0.1 mm; and(2) the permeability of said wet molding substrate is sufficient to permit an air pressure differential across the wet molding substrate to effectively mold said web onto said upper porous nonwoven member to impart a three-dimensional structure to said web.
