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.
Claims13
A method of preparing filter media comprising:
- inserting one or more layers of a nanofiber media between an upper surface and a lower surface, wherein the upper surface and the lower surface are configured to receive a first plurality of needles;
- piercing the nanofiber media with the first plurality of needles;
- withdrawing the first plurality of needles;
- aligning macro fibers along a first surface of the nanofiber media to create a hybrid media;
- inserting the hybrid media between a stripper plate and a stitcher plate;
- piercing the hybrid media with a second plurality of needles;
- and
- withdrawing the second plurality of needles;
- wherein at least a combination of the piercing of the hybrid media and the withdrawing from the hybrid media comprises:
- catching, by the second plurality of needles, macro fibers;
- and
- combining, by the second plurality of needles, the macro fibers with the nanofiber media.
A method of preparing filter media comprising:
- inserting one or more layers of a nanofiber media between an upper surface and a lower surface, wherein the upper surface and the lower surface are configured to receive a plurality of teeth;
- piercing the nanofiber media with the plurality of teeth;
- withdrawing the plurality of teeth;
- aligning macro fibers along a first surface of the nanofiber media to create a hybrid media;
- inserting the hybrid media between a stripper plate and a stitcher plate;
- piercing the hybrid media with a plurality of needles;
- and
- withdrawing the plurality of needles;
- wherein
- at least a combination of the piercing of the hybrid media and the withdrawing from the hybrid media comprises:
- catching, by the plurality of needles, macro fibers;
- and
- combining, by the plurality of needles, the macro fibers with the nanofiber media.
