Publication number: 20080311343Abstract: A microcreped wet laid nonwoven with recoverable stretch suitable for apparel applications such as waistbands and interlinings. The microcreping and heat setting improves dimensional stability after washing and drying cycles, minimizes shrinkage and substantially eliminates the surface wrinkling phenomenon, known in the industry as “alligatoring”, associated with wet laid and other apparel nonwovens.Type: ApplicationFiled: May 9, 2006Publication date: December 18, 2008Inventors: Larry L. Kinn, Rui B. Ferreira, Clement J. Haley, Raymond A. D'Amato

Patent number: 7329623Abstract: A nonwoven web of a wettable fiber matrix, wherein the wettable fiber matrix are thermoplastic polymeric fibers blended with at least one hydrophilic melt additive. In alternate embodiments, the nonwoven web further includes binder fibers which may be wettable or non-wettable or combinations of both.Type: GrantFiled: August 30, 2002Date of Patent: February 12, 2008Assignee: Ahlstrom Mount Holly Springs LLCInventors: Larry L. Kinn, Ashish Mathur, Gregory Neil Henning

Patent number: 7063917Abstract: A nonwoven material having a laminated construction and including a first layer of nonwoven fibers defining a first surface of the material; a second layer of nonwoven fibers defining the opposite surface of the material; and a third layer of nonwoven fibers located between the first and second layers. The layers are bonded together to form a laminate. At least one of the nonwoven layers comprises a nonwoven web of meltblown fibers. Additionally, one or more of the layers has been rendered permanently hydrophilic by forming the nonwoven web from meltspun fibers of a normally hydrophobic polymer having a hydrophilic melt additive incorporated therein.Type: GrantFiled: February 19, 2002Date of Patent: June 20, 2006Assignee: Ahlstrom Mount Holly Springs, LLCInventors: Larry L. Kinn, Clement J. Haley, Gregory N. Henning

Patent number: 6696373Abstract: Nonwoven webs in accordance with the present invention include multicomponent fibers bonded by a multiplicity of bond sites to form a coherent web. The multicomponent fibers include a first component formed of a hydrophobic polypropylene and a second component formed of a blend of a hydrophobic polyolefin and a hydrophilic melt additive. This second component is disposed at the surface of the fibers. The hydrophilic melt additive-modified polyolefin component can be arranged in various configurations in the cross-section of the fiber and the fibers can have various cross sections. For example, the hydrophilic component can occupy a portion of the surface of the fiber, as would occur for example with a side-by-side or segmented pie multicomponent fiber configuration. Alternatively, the modified hydrophilic polyolefin can occupy substantially the entire surface of fiber, as for example by producing the fibers in a sheath core configuration with the hydrophilic modified component forming the sheath.Type: GrantFiled: November 29, 2000Date of Patent: February 24, 2004Assignee: BBA Nonwovens Simpsonville, Inc.Inventors: Larry L. Kinn, Gregory Neil Henning, Clement J. Haley

Patent number: 4973382Abstract: A nonwoven filtration fabric is composed of a plurality of fiber components of dissimilar denier and length which are evenly intermingled and bonded together in a sheet, including a first fiber component of staple polyester fibers of high denier and a textile length, a second fiber component of staple polyester fibers of low denier and shorter length than the first fiber component, a third fiber component of wood pulp fibers of shorter length than the first fiber components, and a suitable binder. The fabric is formed by a wet laid process in which the dissimilar fiber components are evenly mixed and distributed in a homogeneous slurry. A filter media made of the fabric has a high tensile strength, even pore size and distribution, low pressure drop, and is suitable for macrofiltration applications, such as filtering milk.Type: GrantFiled: July 26, 1988Date of Patent: November 27, 1990Assignee: International Paper CompanyInventors: Larry L.
