US Patent:

20080120954, May 29, 2008

Filed:

Nov 8, 2007

Appl. No.:

11/937245

Inventors:

Leonard E. DUELLO - Hewitt TX, US
Thomas D. Hawkins - Waco TX, US
Christopher B. Peart - Madisonville KY, US
Nathaniel J. Nance - Mexia TX, US

International Classification:

B01D 39/16
B29C 65/00

US Classification:

55528, 156 60

Abstract:

The present disclosure relates generally to a nonwoven filtration media comprising a bonded mix of different, discontinuous, thermoplastic resin fibers and optionally discontinuous cellulosic fibers. In some embodiments a tackifier is added to the nonwoven filtration media to provide a sticky or adhesive surface on the fibers. The nonwoven media has an advantageous combination of stiffness, foldability, efficiency and the ability to retain a fold. The nonwoven media can be thermally bonded during the production process. The advantageous combination of mechanical properties allow the disclosed nonwoven media to accept and retain folds and pleats better than some conventional filtration materials while the mix of different fibers provides desirable filtration properties.

B32B 38/16

US Classification:

210508, 156242

Abstract:

Disclosed herein is a multilayer, composite nonwoven material comprising a first’ fibrous nonwoven web having 1 an interior face in contact with an interior face of a second fibrous nonwoven web and a resin binding the fibers in the first and second webs; the fibers of the first web comprising staple length fibers having an. average denier in the range of about 0.9 to about 4.5 and the fibers of the second web comprising staple length fibers having an average denier in the range of about 2.0 to about 6.5, the first web having a different resin binder content than the second web. A fabric formed from the nonwoven material, a fluid filter, and a method of making the nonwoven material also are disclosed.

Abstract:

A water-dispersible nonwoven substrate includes a structured web of fibers. The structured web has a first surface and a second surface. The first surface has substantially filled protrusions extending outwardly from the first surface and connecting regions disposed between the protrusions. The average fiber densities of the protrusions and connecting regions are substantially the same, and the fibers are individualized plant-based fibers, reconstituted cellulosic fibers, or a combination thereof.
