摘要
A method of forming deformations in a nonwoven web includes the steps of: a) providing a precursor nonwoven web; b) providing a pair of forming members which include: a first forming member having a surface comprising a plurality of discrete, spaced apart male forming elements; and a second forming member having a surface comprising a plurality of recesses in the second forming member, wherein the recesses are aligned and configured to receive the male forming elements therein, wherein the recesses have a plan view periphery that is larger than, and may completely surround, the plan view periphery of the male elements; and c) mechanically deforming the precursor nonwoven web with the forming members by placing the precursor nonwoven web between the forming members. At least one of the first forming member and the second forming member has a plurality of discrete surface texture elements thereon. The method forms a nonwoven web having a generally planar first region and a plurality of discrete deformations. The deformations form protrusions that extend outward from the first surface of the nonwoven web and a base opening adjacent to the second surface of the nonwoven web.
