Patent number: 8246730Abstract: The assemblies of the invention can comprise a fine fiber layer having dispersed within the fine fiber layer an active particulate material. Fluid that flows through the assemblies of the invention can have any material dispersed or dissolved in the fluid react with, be absorbed by, or adsorbed onto, the active particulate within the nanofiber layer. The structures of the invention can act simply as reactive, absorptive, or adsorptive layers with no filtration properties, or the structures of the invention can be assembled into filters that can filter particulate from a mobile fluid while simultaneously reacting, absorbing, or adsorbing materials from the mobile fluid.Type: GrantFiled: June 30, 2011Date of Patent: August 21, 2012Assignee: Donaldson Company, Inc.Inventors: Andrew J. Dallas, William Lefei Ding, Jon D. Joriman, Dustin Zastera, James R. Giertz, Veli Kalayci, Hoo Y. Chung

Patent number: 8247069Abstract: The invention relates to a web or filter structure such as the filtration media comprising a collection of fiber comprising a first polymer and a second polymer in a fine fiber or fine fiber web structure. The combination of two polymers provides improved fiber rheology in that the fiber has excellent temperature and mechanical stability. The combination of polymers imparts the properties of elasticity or tackiness, which is desirable for adhering particles to the fiber web, with high temperature resistance.Type: GrantFiled: May 26, 2011Date of Patent: August 21, 2012Assignee: Donaldson Company, Inc.Inventor: Veli Kalayci

Patent number: 8141716Abstract: A polymer alloy has been developed comprising a polysulfone and a vinyl lactam polymer. The resulting alloy has excellent thermal characteristics and even in the presence of substantial quantities in vinyl lactam polymers, has solvent resistance to both organic and aqueous solvent materials. The materials, when dissolved in solvents, can be spun from a variety of solvents into a variety of useful fiber materials. The resulting fine fiber, microfiber and nanofiber materials have excellent thermal and chemical resistance for a variety of fiber applications. The polymer alloys of the invention can be spun into nanofiber mats that can act as a filtration media and can also be combined into conventional substrate materials for fabrication into filter structures.Type: GrantFiled: February 10, 2011Date of Patent: March 27, 2012Assignee: Donaldson Company, Inc.Inventors: Ismael Ferrer, Richard S.

Publication number: 20060230731Abstract: A web can comprise a substantially continuous fiber mass and a separation means dispersed into the fiber. The web having a preferred thickness resulting from forming a polymer material and a particulate into a fine fiber layer can have a variety of end uses. A filtration media can include a structure comprising such a web of fine fiber and a substantial volume of particulate embodiment of the separation means. The resulting fine fiber structure provides an improved filtration medium having substantial depth, thickness, and a layered structure. The improved properties of the web results from inclusion of the separation or spacer particulate.Type: ApplicationFiled: February 13, 2006Publication date: October 19, 2006Inventors: Veli Kalayci, Douglas Crofoot, Timothy Grafe, Kristine Graham
