摘要：
Processes for making micro-textured webs. The process comprises providing a precursor web 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 moving the web through a deformation zone of the mated forming structures, wherein the voids of the first forming structure engage with the protrusions of the second forming structure at an engagement position. Discrete three-dimensional elements are formed in the web as the protrusions on the second forming structure engage with the voids on the first mating structure. At least one protrusion has center-to-center spacings of less than about 800 microns with at least three of its adjacent protrusions.
