The application relates to a nonwoven composite containing a plurality of solid regions and a plurality of porous regions. The solid and porous regions form a repeating pattern on the surface of the composite. The solid regions contain a solid region nonwoven layer, an optional solid region polymer-fiber infused layer, and a solid region cap layer. The solid region nonwoven layer contains a plurality of first staple fibers and less than about 5% by volume of a first polymer. The solid region cap layer contains the first polymer and less than about 5% by volume of the first staple fibers. The porous regions contain a porous region nonwoven layer and a porous region polymer-fiber infused layer. The porous region nonwoven layer contains a plurality of the first staple fibers and less than about 5% by volume of a first polymer. The porous region polymer-fiber infused layer contains a plurality of pores.
A nonwoven composite having an upper surface and a lower surface, the upper surface and the lower surface further defining a composite thickness, wherein the nonwoven composite comprises a plurality of solid regions and a plurality of porous regions, wherein the solid regions have an average surface area size of greater than about 1 mm2, wherein the porous regions have an average surface area size of greater than about 1 mm2, wherein the porous regions and solid regions form a pattern on the lower surface of the nonwoven composite,
