Abstract:
1. A process for producing a nonwoven laminate wipe comprising: forcing polymeric fibers through a first porous forming surface to produce a first polymeric layer having a plurality of projections, each projection surrounded by a valley, wherein the first polymeric layer is formed with an air pressure differential, the first porous forming surface having a first side on which the polymeric fibers are collected to form said first polymeric layer and a second side opposite the first side, each projection of the first polymeric layer extending through the first porous forming surface and outward of the second side thereof during the production of the first polymeric layer; forcing polymeric fibers through a second porous forming surface to produce a second polymeric layer having a plurality of projections, each projection surrounded by a valley, wherein the second polymeric layer is formed with an air pressure differential, the second porous forming surface having a first side on which the polymeric fibers are collected to form said second polymeric layer and a second side opposite the first side, each projection of the second polymeric layer extending through the second porous forming surface and outward of the second side thereof during the production of the second polymeric layer; arranging the first and second polymeric layers with projections of said layers opposing each other and in contact with each other wherein opposing valleys form a void volume between the first and second polymeric layers; and bonding the first and second polymeric layers together at the opposed projections.
