Abstract
A method for applying a high pressure liquid jet or stream to a web of polymeric film while the film is supported on a moving forming structure to produce a novel microbubbled substantially fluid-impervious web exhibiting substantially the same consumer preferred soft and silky tactile impression and reduced noise generation levels heretofore only achievable in microapertured, and hence substantially fluid pervious polymeric webs. In a particularly preferred embodiment, the microbubbled polymeric web exhibits a fine-scale pattern of discrete mushroom shaped surface aberrations, each of said surface aberrations having its amplitude oriented substantially perpendicular to the surface in which the surface aberration originates. Apparatus for producing microbubbled webs either in 'planar' or 'macroscopically expanded' form are also disclosed.
