Macroscopically expanded three-dimensional plastic web exhibiting non-glossy visible surface and cloth-like tactile impression and process for its manufacture.

摘要

A macroscopically expanded three-dimensional plastic web exhibiting a non-glossy visible surface, and, if desired, a cloth-like or fiber-like tactile impression. The visible surface of a macroscopically expanded three-dimensional plastic web of the present invention is preferably provided with a regularly spaced, microscopic pattern of surface aberrations which is too fine to be discernible by the naked eye when the perpendicular distance between the viewer's eye and the plane of said web is 30 cm or greater, but which pattern is effective in substantially eliminating specular reflection of incident light. Said webs may be produced by means of a one-sided forming process wherein said surface aberrations are transmitted through the thickness of said web during processing or by means of a two-sided forming process wherein said surface aberrations are imposed directly onto the visible surface of said web. Macroscopically expanded three-dimensional plastic webs of the present invention may be effectively employed as alternatives for cloth and fibrous structures which contact the wearer's skin, as well as for new and existing product applications where a non-plastic visual and tactile impression are desired.
