Patent number: 11359308Abstract: High permeability curly fibers with enhanced fiber strength are produced by mercerizing cellulosic fibers. The fibers have relatively high values for curl, kink level, wet tensile strength, and bulk density when compared with current fibers. The disclosed fibers can be used in a wide range of applications including paper products such as filters.Type: GrantFiled: July 31, 2020Date of Patent: June 14, 2022Assignee: GP CELLULOSE GMBHInventors: Alan Jeffrey Campbell, Sonja McNeil Fields, Danny R. Moore, Stephen Skirius

Patent number: 10300457Abstract: The present invention is directed to an absorbent material and the fibers therein, having two or more layers including an upper surface layer which has on the outer surface of the layer one or more surface area zones which are more wettable zones and adjacent thereto one or more less wettable zones, where the more wettable zones have a greater hydrophilicity than the less wettable zone. The present invention is also directed to the fibers therein, which contain polyvalent cation-containing compounds and fatty acid containing compounds. The present invention also provides for methods of treating fibers or solid materials and processes of producing the hydrophobic materials.Type: GrantFiled: December 23, 2014Date of Patent: May 28, 2019Assignee: GEORGIA-PACIFIC NONWOVENS LLCInventors: Jacek K. Dutkiewicz, Stephen A. Skirius, Sonja McNeil Fields, Lynn Hung Rushing, David Jay Smith, Michael Kalmon, Ronald Timothy Moose, Ryszard Fryczkowski, Beata Fryczkowska, Monika Rom
