Abstract
The present application is direction to a system and method for preparing filter media from macro and nanofibers by ventilating a nanofiber media, combining the nanofiber media with macro fibers to form a hybrid media, inserting the hybrid media between a stitching plate and a stripper plate and alternatively inserting and withdrawing needles to combine the macro fibers with the nanofiber media and create a fiber web along at least one surface of the nanofiber media.
