The reversible color-changing ink formulation includes about 55-98% by weight of a polymer binder, about 0.1-20% by weight of a reversible color-changing dye that reversibly changes between a first color and a second color at a pH of about 5.5 to about 8.0, and optional amounts of plasticizer, inorganic particulate filler, and color brightener. During use, the nonwoven wipe is impregnated with a sanitizer solution that contains a quaternary ammonium compound. The nonwoven wipe reversibly changes between a first color when impregnated with the sanitizer solution and a second color when the sanitizer solution is depleted during use. The change to the second color indicates the need to recharge the nonwoven wipe with the sanitizer solution, whereupon the first color returns.Type: GrantFiled: October 15, 2010Date of Patent: July 8, 2014Assignee: Illinois Tool Works Inc.Inventors: Paul Richard Jelonek, Ernani Bernardo

Multi-functional yarns and fabrics having anti-microbial, anti-static and anti-odor characterisitics
Patent number: 8771831Abstract: The present invention is directed to yarns and fabrics that exhibit anti-static, anti-odor, and anti-microbial properties. The yarn is comprised of several groups of predetermined fibers. One of these groups of predetermined fibers comprises fibers that exhibit anti-microbial, anti-odor and anti-static characteristics. In one embodiment, the yarn comprises a first plurality of fibers, a second plurality of fibers that are different from the fibers of the first plurality, and a third plurality of fibers that are different from the fibers of the first and second pluralities. In one embodiment, the fibers which exhibit anti-microbial, anti-odor and anti-static properties are metallic coated fibers. Other fibers used to form different embodiments of the yarns include cotton, nylon, polyester, wool, meta-aramid fibers, para-aramid fibers, and stretch fibers.Type: GrantFiled: December 23, 2005Date of Patent: July 8, 2014Assignee: The United States of America as Represented by the Secretary of the ArmyInventor: Carole A.

Patent number: 8759235Abstract: A new orthopedic prayer mat proposed, whereas the new orthopedic prayer mat has a multiple layered structure. The top layer is made from microfiber which is antimicrobial, anti-molding, water-resistant, anti-dust and heat-resistant. The bottom layer is an anti-slip layer to prevent the user from physical injury in any situation while using the mat, and a soft polyurethane layer and an anti-fatigue layer or a hard polyurethane layer are arranged between the top microfiber layer and the bottom anti-slip layer in order to absorb pressure pressure and providing support, and the soft and hard polyurethane layer are combined at an angle to adjust the ratio of the weight-absorption and bearing to form the orthopedic prayer mat. Further the angle between the layers is tailored for users according to user's weight, height, body structure type and healthy conditions.Type: GrantFiled: May 10, 2011Date of Patent: June 24, 2014Inventor: Nader Sabry

Publication number: 20140154940Abstract: A controlled release biocidal salt of a first component comprises a cation of a N?—(C1-C22) alkanoyl di-basic amino acid alkyl (C1-C22) ester cationic biocidal molecule and a second component comprising an anion of a monomeric anionic molecule having insignificant biocidal activity. The salt is characterized such that when the salt is exposed to an aqueous medium, the salt partially dissolves thereby releasing biocidal ions in an amount sufficient to exceed the MIC or MBC of a target bacteria being controlled, and further characterized as leaving a residual reservoir of undissolved salt capable of releasing more biocidal ions as the salt is consumed or otherwise removed from the environment encompassing the target bacteria. The preferred cationic biocidal molecule comprises N?-lauroyl-L-arginine ethyl ester (“LAE”).Type: ApplicationFiled: February 10, 2014Publication date: June 5, 2014Applicant: Nevada Naturals Inc.Inventors: Anthony J.

Patent number: 8703627Abstract: An antiadhesive material that is excellent in biocompatibility and bioabsorbability, as well as excellent strength in suturing and bonding, is provided. A reinforcing material 12 made of a biodegradable polymer is placed in a gelatin solution so that the reinforcing material 12 is impregnated with the solution, and the gelatin is caused to gelate and dried. By so doing, an antiadhesive material in which a gelatin film 11 and the reinforcing material 12 are integrated is obtained. The reinforcing material 12 preferably is arranged in a portion of the gelatin film 11 to be subjected to suturing, and preferably is arranged along a periphery of the gelatin film 11. The gelatin film 11 preferably is a cross-linked gelatin film, and the reinforcing material 12 preferably is a nonwoven fabric.Type: GrantFiled: June 12, 2002Date of Patent: April 22, 2014Assignees: Gunze Limited, JMS Co., Ltd.Inventors: Shojiro Matsuda, Yoshimi Tanaka, Yoshito Ikada

Patent number: 8684189Abstract: Described is the application of layer-by-layer (LbL) electrostatic assembly techniques to electrospun nanofibers in order to fabricate novel, breathable electrospun fiber-based chemical and biological detoxifying protective fabrics and filters. The combination of layer-by-layer electrostatic assembly and electrospinning technique allows one to take advantage of high specific surface area, light weight and breathability of electrospun fiber mats while simultaneously providing the versatility to incorporate different functional polyelectrolytes to achieve multifunctional coatings for both chemical and biological protection together. The functionalized fiber mats can be incorporated into breathable chemical and biological protective fabrics, filters and masks. In addition, LbL electrostatic coating of porous non-woven materials provides the versatility to generate multifunctional polymer-based membrane materials for other applications.Type: GrantFiled: July 21, 2010Date of Patent: April 1, 2014Assignee: Massachusetts Institute of TechnologyInventors: Liang Chen, Lev E.
