A polymeric web exhibiting a soft and silky tactile impression on at least one side thereof is disclosed. The silky feeling side of the web exhibits a pattern of discrete hair-like fibrils, each of the hair-like fibrils being a protruded extension of the web surface and having a side wall defining an open proximal portion and a closed distal portion. The hair-like fibrils exhibit a maximum lateral cross-sectional diameter of between 2 and 5 mils, and an aspect ratio from 1 to 3. Methods and apparatus for making the polymeric web utilize a three-dimensional forming structure having a plurality of protrusions being generally columnar forms having an average aspect ratio of at least about 1.
A polymeric web comprising a polymeric film, said web exhibiting a soft and silky tactile impression on at least one side thereof, said silky feeling side of said web exhibiting a pattern of discrete generally columnar protruded extensions, wherein said generally columnar protruded extensions are an integral extension of said film, each said generally columnar protruded extension being formed by local plastic deformation of said film and having a side wall defining an open proximal portion and a closed distal portion, and having a maximum lateral cross-sectional dimension at or near said open proximal portion, wherein said generally columnar protruded extensions exhibit an average diameter of between 50 microns (0.02 inch) and 130 microns (0.005 inch), and an aspect ratio of from 1 to 3.
A three-dimensional polymeric web exhibiting a soft and silky tactile impression on at least one surface thereof, said web comprising a macroscopically expanded pattern of interconnecting members defining macroscopic surface aberrations, said macroscopic surface aberrations defining a first surface in a first plane of said web, and a second surface in a second plane of said web, said first surface of said web exhibiting a pattern of discrete generally columnar protruded extensions, each of said generally columnar protruded extensions being an integral extension of said first surface and formed by local plastic deformation of said web and having a side wall defining an open proximal portion and a closed distal portion, said generally columnar protruded extensions having a height and an average lateral cross-sectional diameter at ½ said height of between 50 microns (0.002 inch) and 130 microns (0.005 inch), an average center-to-center spacing of from about 100 microns to 250 microns (0.004 inch to 0.0 10 inch), and an aspect ratio from 1 to 3.
A disposable absorbent article comprising a fluid pervious polymeric web exhibiting a soft and silky tactile impression on at least one surface thereof, said silky feeling surface of said web exhibiting a pattern of discrete generally columnar protruded extensions, wherein said generally columnar protruded extensions are an integral extension of said web surface, each said generally columnar protruded extension being formed by local plastic deformation of said film and having a side wall defining an open proximal portion and a closed distal portion, and having a maximum lateral cross-sectional dimension at or near said open proximal portion, wherein said generally columnar protruded extensions exhibit an average diameter of between 50 microns (0.002 inch) and 130 microns (0.005 inch), and an aspect ratio of from 1 to 3.
