PROCESS FOR MAKING A MICRO-TEXTURED WEB

摘要

Processes for making micro-textured webs are disclosed. The present process includes the steps of providing a precursor web; providing a first pair of mated forming members including a first forming member and a second forming member forming a first deformation zone therebetween; moving the precursor web through the first deformation zone forming a first plurality of structures; providing a second pair of mated forming members including a third forming member and a fourth forming member forming a second deformation zone therebetween; moving the precursor web through the second deformation zone forming a second plurality of structures, and wherein the first plurality of structures is different than the second plurality of structures.

1. A process for making a micro-textured web, the process comprising:
a. providing a precursor web; b. providing a first pair of mated forming members including a first forming member and a second forming member forming a first deformation zone therebetween, wherein the first forming member comprises a plurality of protrusions and wherein at least the second forming member comprises a plurality of voids; c. moving the precursor web through the first deformation zone, wherein the voids of the second forming member engage with the protrusions of the first forming member at an engagement position thereby forming a first plurality of structures on the precursor web; d. providing a second pair of mated forming members including a third forming member and a fourth forming member forming a second deformation zone therebetween, wherein the third forming member comprises a plurality of voids and the fourth forming member comprises a plurality of protrusions; and e. moving the precursor web through the second deformation zone, wherein the voids of the third forming member engage with the protrusions of the fourth forming member at an engagement position thereby forming a second plurality of structures on the precursor web,wherein the first plurality of structures is different than the second plurality of structures.
