Abstract
Three-dimensional web materials, more particularly, a three-dimensional web material having a first side and a second side are disclosed herein. The first side comprises at least one region having a plurality of spaced elongate three-dimensional protrusions extending outwardly from the first side which are preferably unitarily formed from the web material. The elongate protrusions form an amorphous pattern of a plurality of elongate two-dimensional geometrical shapes.
Claims19
A three-dimensional web material having a machine direction and a cross-machine direction orthogonal and coplanar with said machine direction, said material having a first side and a second side, wherein said first side comprises an amorphous pattern of spaced three-dimensional protrusions extending outwardly from a base disposed upon said first side, said base comprising an elongate two-dimensional geometrical shape disposed in said machine and cross-machine directions, each of said elongate two-dimensional geometrical shapes having an aspect ratio relative to said machine and cross-machine directions of greater than 1 and a longitudinal axis having an angle of from about −10 degrees to about +10 degrees relative to said cross-machine direction, said protrusions having a statistically-controlled degree of randomness.
An embossment pattern for a three-dimensional web material having a machine direction, a cross-machine direction orthogonal and coplanar with said machine direction, and a first side, said embossment pattern comprising a plurality of spaced three-dimensional protrusions extending outwardly from said first side, each of said plurality of spaced three-dimensional protrusions having an elongate base disposed upon said first side, said elongate base comprising an elongate two-dimensional geometrical shape disposed in said machine and cross-machine directions, each of said elongate bases having an aspect ratio ranging from greater than 1 to about 5 in said machine direction and a longitudinal axis having an angle of from about −10 degrees to about +10 degrees relative to said cross-machine direction, said protrusions having a statistically-controlled degree of randomness.
