  • Publication number: 20080268732
    Abstract: Durable non-electrically conductive metal treatments (such as coatings or finishes) for yarns and textile fabrics are provided. Such treatments preferably comprise silver and/or silver ions; however, other metals, such as zinc, iron, copper, nickel, cobalt, aluminum, gold, manganese, magnesium, and the like, may also be present or alternatively utilized. Such a treatment provides, as one example, an antimicrobial fiber and/or textile fabric which remains on the surface and does not permit electrical conductivity over the surface. The treatment is extremely durable on such substrates; after a substantial number of standard launderings and dryings, the treatment does not wear away in any appreciable amount and thus the substrate retains its antimicrobial activity (or other property).

  • Patent number: 6946433
    Abstract: Durable antimicrobial treatments for textile fabrics are provided. Such treatments preferably comprise silver ions, particularly as constituents of inorganic metal salts or zeolites. This particular treatment requires the presence of a resin binder, either as a silver-ion overcoat or as a component of a dye bath mixture admixed with the silver-ion antimicrobial compound. Such a treatment is extremely durable on such substrates; after a substantial number of standard launderings and dryings, the treatment does not wear away in any appreciable amount and thus the substrate retains its antimicrobial activity. The particular treatment method, as well as the treated textile fabrics are also encompassed within this invention.

  • Patent number: 6797278
    Abstract: Broadly defined sol-gel films for the coating of solid substrates, wherein such sol-gel films provide effective and durable antimicrobial properties. The utilization of such films permits relatively low-temperature production of antimicrobial substrates, such as ceramics, metals (e.g., stainless steel, brass, and the like), plastics (e.g., polyimides, polyamides, polyacrylics, and the like), glass (e.g., borosilicates, and the like), as compared with typical glazes for ceramics and the like. The inventive films comprise, as the primary antimicrobial active ingredients, certain metal-containing inorganic or organic antimicrobial compounds, such as, preferably, metal-containing ion-exchange, oxide, glass, sulfadiazine, and/or zeolite compounds (most preferably, including silver therein as the metal component).

  • Publication number: 20040076792
    Abstract: Topical antimicrobial floor covering treatments comprising solid antimicrobial particles that become embedded within target fibers to impart a durable antimicrobial finish are provided. Such a topical treatment includes specific inorganic antimicrobial metal ion-based solid compounds, such as silver ion-exchange compounds, silver zeolites, and/or silver glasses, which is present within a liquid medium or mixed with another solid treatment agent. Such treatments also optionally include compositions of stain resistant agents, anti soil-redeposition compounds and liquids, surfactants, antistatic agents, and the like, to impart other characteristics to the target carpeted products. Such carpet treatments thus impart excellent antimicrobial characteristics at both the surface of the carpet pile, as well as within the pile itself.

  • Patent number: 6641829
    Abstract: Carpeted floor covering articles comprising carpet pile fibers to which a topical antimicrobial application of solid particles has been applied either during or after product manufacture (such as part of a cleaning or treatment process) are provided. Such a topical treatment includes specific inorganic antimicrobial metal ion-based solid compounds, such as silver ion-exchange compounds, silver zeolites, and/or silver glasses, which may or may not be dispersed within a liquid medium for ease in handling and application. Such treatments also optionally include compositions of stain resistant agents, anti soil-redeposition compounds and liquids, surfactants, antistatic agents, and the like, to impart other characteristics to the target carpeted products. Such carpeted products thus exhibit excellent antimicrobial characteristics at both the surface of the carpet pile, as well as within the pile itself.

  • Patent number: 6640371
    Abstract: Durable antimicrobial treatments for high pressure treatments (such as package dyeing) for specific dyed yarns for further incorporation within textile fabrics are provided. Such treatments preferably comprise silver ions, particularly as constituents of inorganic metal salts or zeolites. This particular treatment requires the presence of a resin binder as a component of the dye bath formulation admixed with the silver-ion antimicrobial compound, the formulation then forced through a target yarn spool in order to provide a finish over substantially all of the target yarn. The yarn may then be knit, woven, pressed, laid-in, etc., into a textile fabric exhibiting antimicrobial properties. Such a treatment has been found to be extremely durable on such substrates; after a substantial number of standard launderings and dryings, the treatment does not wear away in any appreciable amount and thus the substrate retains its antimicrobial activity.
