non-woven material production method having isolated three-dimensional deformations with wide-base openings using surface textured forming elements

摘要

The present invention relates to a method of forming deformations in a nonwoven web that includes the steps of: a) providing a precursor nonwoven web; b) providing a pair of forming elements comprising: a first forming element having a surface comprising a plurality of distinct and spaced male forming elements; and a second forming element having a surface comprising a plurality of recesses in the second forming element, wherein the recesses are aligned and configured to receive male forming elements therein, wherein the recesses have a periphery; planar, which is larger than and may completely surround the periphery, plan view, of the male elements; and c) mechanically deforming the precursor nonwoven web with the forming elements by placing the precursor nonwoven web between the forming elements. at least one of the first forming element and the second forming element has a plurality of distinct surface texture elements thereon. The method forms a nonwoven mat having a generally flat first region and a plurality of distinct deformations. the deformations form protrusions extending outwardly from the first surface of the nonwoven web and a base opening adjacent the second surface of the nonwoven web.
