Publication number: 20120070342Abstract: A light-activated antimicrobial article is disclosed, consisting essentially of an acridine dye covalently bonded without a linking group to a nylon material. The article may be made using electron beam processing. The article in combination with light absorbed by the acridine dye may be used to inhibit the growth of microorganisms. A photosensitive nylon material in which the acridine dye is disposed on the nylon material may also be used. Medical kits that include a light source and an article having the acridine dye are disclosed.Type: ApplicationFiled: June 23, 2010Publication date: March 22, 2012Inventors: Maria A. Appeaning, Sonja K. Belgrade, Douglas E. Weiss, Narina Y. Stepanova, Caroline M. Ylitalo

Patent number: 8138106Abstract: An odor-inhibiting fiber having a cellulosic fiber and an odor-inhibiting formulation. The odor-inhibiting formulation may contain an odor-inhibiting agent, such as a biocide, an enzyme, a urease inhibitor. The odor-inhibiting formulation also may contain a liquid carrier such as a hydrophobic or hydrophilic organic liquid, or a mixture of a hydrophobic and hydrophilic organic liquid. The cellulosic fiber is impregnated with the odor-inhibiting formulation to produce fiber having odor-inhibiting characteristics. The resultant odor-inhibiting fiber is useful in making absorbent articles with odor-inhibiting characteristics. The fiber of the embodiments prevents odor by inhibiting bacteria growth and ammonia production, especially when used in an absorbent article such as a diaper or adult incontinence device.Type: GrantFiled: September 30, 2005Date of Patent: March 20, 2012Assignee: Rayonier TRS Holdings Inc.Inventors: Othman A. Hamed, Harry J. Chmielewski

Publication number: 20120015576Abstract: The invention relates to a planar or shaped textile material comprising or constituted of fibers, at least part of the fibers being coated with a hydrolytically condensed inorganic/organic hybrid material having single-walled or multi-walled carbon nanotubes which are embedded therein, optionally covalently bound thereto. The carbon nanotubes are preferably functionalized, especially with carboxylic acid groups or sulfanilic acid groups. The textile material is suitable for producing protective clothing, barrier materials or the like. The invention further relates to the use of the above-defined hybrid material as a coating material which imparts stain-resistance and/or antimicrobial properties to the coated substrate.Type: ApplicationFiled: March 18, 2010Publication date: January 19, 2012Inventors: Sabine Amberg-Schwab, Annett Halbhuber, Detlev Uhl, Karl-Heinz Haas

Publication number: 20120015574Abstract: A method for production of a reactive polyurethane emulsion for use in impregnating and coating a textile fabric includes reacting polyols alone or in combination with at least one of diols and triols with a substoichiometric amount of diisocyanates so as to form medium-viscosity, OH-terminated prepolymers. The prepolymers are mixed with an external emulsifier. At least one of a diisocyanate, a triisocyanate and a polyisocyanate are added so as to bring about a crosslinking of the prepolymers.Type: ApplicationFiled: March 25, 2010Publication date: January 19, 2012Applicant: CARL FREUDENBERG KGInventors: Birgit Severich, Thomas Schauber, Horst Muehlfeld, Robert Groten, Bjoern Hellbach, Ansgar Komp, Christian Waschinski
