Inventor(s): Lawrence Romano, Kenneth Close, Larry Brown and Steven Kalmanson
Company: Kimberly-Clark Worldwide, Inc.
A plurality of wipes has been issued a patent. Each wipe includes at least one nonwoven web featuring an edge portion adjoining a main portion. The web has a top surface and a spaced apart opposite bottom surface. The width of the web is perpendicular to the length of the web. The top surface of the main portion has a top plane and the bottom surface of the main portion has a bottom plane. The top and bottom planes are parallel to one another and a z-directional dimension of the web extends through the top and bottom planes and is orthogonal to the top and bottom planes. The edge portion includes an edge treatment, at least a portion of which is permanently deformed in a non-random pattern in the z-directional dimension. The top surface of the edge portion makes up a top edge plane and the bottom surface of the edge portion defines a bottom edge plane. At least one of the top edge plane and the bottom edge plane is outside of a bounded region between the top and bottom planes of the main portion. Each wipe is folded upon itself at least once and is positioned relative to adjacent wipes to form a stack of wipes.
