Abstract
Methods and systems are provided for a process to generate a nonwoven textile. In one example, the nonwoven textile may have layered, zonal properties resulting from entangling of two or more types of staple fibers through a merging region between the layers of staple fibers while maintaining distinct zones, each zone comprising a type of staple fiber. Furthermore, the process may include embedding a filament layer into the nonwoven textile via a continuous assembly line.
