Apparatus for Making Polymeric Web Exhibiting a Soft and Silky Tactile Impression

摘要

A method for making a polymeric web exhibiting a soft and silky tactile impression on at least one side thereof, the method comprising the steps of: providing a forming drum comprising at least one vacuum chamber; providing a forming structure, the forming structure being moveable upon the forming drum; extruding a precursor web directly onto the forming structure; moving the forming structure adjacent the vacuum chamber; applying vacuum at a sufficient level to induce a sufficient partial pressure to conform the precursor web to the forming structure; providing a source of heat; and annealing the precursor web by heating the precursor web; thereby forming the polymeric web exhibiting a soft and silky tactile impression on at least one side thereof, the polymeric web comprising hair-like fibrils having closed distal ends and an average aspect ratio of at least about 0.5.
