Abstract:
1. A process for making a micro-textured web, the process comprising: a. providing a precursor web; b. providing a pair of mated forming structures, including a first forming structure and a second forming structure, wherein at least the first forming structure comprises voids, and wherein at least the second forming structure comprises protrusions; and c. moving the precursor web through a deformation zone between the pair of mated forming structures at a line speed of at least about 6 m/s, wherein the voids of the first forming structure engage with the protrusions of the second forming structure at an engagement position; wherein discrete three-dimensional elements are formed in the precursor web as the protrusions on the second forming structure engage with the voids on the first forming structure; and wherein at least one protrusion has center-to-center spacings of less than about 800 microns with at least three of its adjacent protrusions.
