Patent number: 11952657Abstract: This invention relates to a method for hiding stains in medical dressings and other textile substrates. The method includes applying a metallic silver coating to a textile substrate via a plasma enhanced chemical vapor deposition (PECVP) process. The metallic silver coating effectively hides any stain that comes into direct contact with the treated substrate by transferring the liquid beneath the surface of the coating. The invention also relates to textile substrates containing metallic silver coatings.Type: GrantFiled: April 19, 2020Date of Patent: April 9, 2024Assignee: Milliken & CompanyInventors: Rajib Mondal, Matthew I. Foote, Gregory A. Satterfield, II, Cristina M. Acevedo, Geoffrey R. Haas

Publication number: 20220273495Abstract: This disclosure relates to a multi-layer wound care device having absorption and fluid transfer properties. The wound care device contains capillary force one-way pumps that are capable of transporting fluid, such as wound exudate, away from a wound site to the opposite side of the wound care device, which functions as a segregated fluid reservoir. This fluid transport mechanism generally aids in reducing wound maceration by removing excess wound fluid and the protease enzymes and infectious bacteria contained within the wound fluid. The wound care device performs this function, often times for multiple days, without the loss of the physical integrity of the wound care device. In addition to providing a uni-directional fluid transport mechanism, the wound care device provides improved absorption properties.Type: ApplicationFiled: May 18, 2022Publication date: September 1, 2022Inventors: Rajib Mondal, Matthew I.

Patent number: 7858674Abstract: This disclosure relates generally to molded rubber articles such as the type used in water contact applications. More particularly, this disclosure is directed to molded rubber articles containing antimicrobial agents that control biofilm growth on the surface of the molded article. The molded rubber article is comprised of curable rubber compounds and a combination of both inorganic silver-containing antimicrobial agents and organic antimicrobial agents. An exemplary molded rubber article comprises ethylene propylene diene monomer rubber, silver-containing ion exchange antimicrobial agent, and an organic antifungal agent such as zinc pyrithione.Type: GrantFiled: February 5, 2007Date of Patent: December 28, 2010Assignee: Milliken & Co.Inventors: Geoffrey R Haas, Robert C Kerr, Carolina Mateus, David L Morris, Bhawan Patel, Jenci Kurja

Publication number: 20090032063Abstract: This invention relates to solid cleaning compositions and the method for using the solid compositions to clean appliances and other soiled surfaces. The solid cleaning composition is generally comprised of a majority by weight of a cleaning active system; ingredients for forming the cleaning active system into a solid form; and optionally, a fragrance. The solid cleaning composition is ideally suited for reducing and/or eliminating microbial growth, including biofilm growth, contained within and/or on appliances, particularly those appliances that have water contact surfaces such as washing machines and dishwashers. The solid cleaning composition further provides reduction and/or elimination of undesirable odor and staining typically associated with such microbial growth.Type: ApplicationFiled: July 30, 2007Publication date: February 5, 2009Inventors: Geoffrey R. Haas, Emily W. Michaels, Carolina Mateus, Robert L. Schuette, Walter P. Horton

Publication number: 20040017021Abstract: Improvements in increasing the amount of available silver in thermoplastic articles comprising certain silver-containing antimicrobial agents are provided. Such an invention requires the incorporation of a sufficient amount of a carboxylic acid salt within the thermoplastic article simultaneously with the necessary silver-containing antimicrobial agent. Certain carboxylic acid salts are standard acid scavengers for thermoplastic applications; however, the amounts required within this inventive thermoplastic article is well in excess of that commonly added within such articles. Surprisingly, such an excess amount of such standard salts, as well as other non-standard salts, present within the target thermoplastic causes the release of greater amounts of silver to the target article's surface, thereby permitting a greater degree of antimicrobial activity, among other potential benefits for such an increase in surface-available silver.Type: ApplicationFiled: July 15, 2003Publication date: January 29, 2004Inventors: Erik Laridon, Robert Dankel, Geoffrey R. Haas

Patent number: 6555599Abstract: Ethylene-propylene diene monomer (EPDM) rubber-containing articles that exhibit highly desirable long-term effective antimicrobial characteristics are provided. Such articles are in either solid or blown (foam or sponge) state (or combinations of both in multilayered forms) that can be utilized in a variety of different applications. As silver-based compounds are deleteriously affected by utilization of standard curing agents and curing accelerators, such as sulfur-based compounds and/or systems, the ability to provide such an effective antimicrobial vulcanized rubber article is rather difficult. However, this invention encompasses the presence of different non-sulfur-based curing systems and agents, such as peroxides, as one example, that permit vulcanization and do not irreversibly bind silver ions thereto, thereby resulting in long-term antimicrobial performance of the ultimate rubber article itself.Type: GrantFiled: March 26, 2001Date of Patent: April 29, 2003Assignee: Milliken & CompanyInventors: John G. Lever, Geoffrey R. Haas, Bhawan Patel

Patent number: 6455610Abstract: Certain non-silicone pre-vulcanized raw rubber formulations that include silver-based compounds to provide highly desirable long-term antimicrobial characteristics within the ultimate cured rubber articles made therefrom are provided. Such formulations are intended to be vulcanized to provide solid or blown (foam or sponge) rubber articles which can be utilized in a variety of different applications (as well as multi-layered composites including such antimicrobial rubber. As silver-based compounds are deleteriously affected by utilization of standard curing agents and curing accelerators, such as sulfur-based compounds and/or systems, the ability to provide such an effective antimicrobial vulcanized rubber article is rather difficult.Type: GrantFiled: March 23, 2001Date of Patent: September 24, 2002Assignee: Milliken & CompanyInventors: John G.

Patent number: 6448306Abstract: Certain butadiene and/or natural rubber articles, such as acrylonitrile-butadiene rubber (NBR), natural rubber, and derivatives thereof, that exhibit highly desirable long-term effective antimicrobial characteristics. Such formulations are intended to be vulcanized to provide solid or foam rubber articles which can be utilized in a variety of different applications. Preferably such butadiene rubber formulations comprise silver-based antimicrobial compounds. As such silver-based compounds are deleteriously affected by utilization of standard non-silicone-rubber curing agents, such as sulfur-based catalysts, the ability to provide such an effective antimicrobial vulcanized rubber article is rather difficult. However, the invention encompasses the utilization of different catalyst species that permit vulcanization and silver stability for long-term antimicrobial performance of the silver-based compounds.Type: GrantFiled: March 23, 2001Date of Patent: September 10, 2002Assignee: Milliken & CompanyInventors: John G.
