A nonwoven laminate comprising a carded staple fiber nonwoven and a filament nonwoven, which are mechanically bonded by hydraulic needling, and comprising a first and second surface, wherein both the first and second surface of said nonwoven laminate have perforations distributed in a pattern, the second surface of said nonwoven laminate has a texture of elevations extending parallel to each other, and said perforations are disposed between said elevations, wherein said perforations are arranged in a hexagonal pattern, wherein each of said elevations is continuous and line-shaped and comprises compacted fibers of the carded staple fiber nonwoven and the filament nonwoven, wherein the compacted fibers form parallel strands within the elevations for capillary liquid transport and any two of the elevations adjacent to each other define there-between a channel for pressure-driven liquid transport and said line-shaped elevations extend at an angle of 90° relative to an axis of symmetry S1 which determines the orientation of the hexagonal pattern of said perforations.
