  • Publication number: 20130323290
    Abstract: Antitoxic fibers and fibrous media contain impregnated material including an antitoxin. A method for producing antitoxic fibers and fibrous media includes impregnating a fibrous media by dipping in a dipping solution containing a concentrate of an antitoxin to form a fiber with impregnated material including an antitoxin. The impregnated material is at least about 1.0% to about 2.5% by weight of the fibers and includes additive chemical components including at least one of an anionic, cationic or nonionic component, an oil and/or an organic solvent, and an alcohol. The additives include those found in a spin finish. The antitoxin is in an amount of at least 0.1% by weight of the fiber. The manufacturing process can be applied to any woven or nonwoven media.

  • Publication number: 20130039968
    Abstract: The invention provides a novel method of generating fabrics with outstanding antitoxic properties. The antitoxic properties are imparted to the fabric by introducing an active agent such as an antimicrobial or antiviral agent to the fabric. The active agent may be introduced into the fabric at multiple stages of the manufacturing process. For nonwoven fabrics, the active agent can be introduced during web formation and/or during post-processing steps. The fabrics produced in accordance with the present invention have widespread utility. For instance, they can be used as wound dressings, gowns, drapes, air filters, protective clothing and wipes.

  • Patent number: 8071713
    Abstract: The invention provides a novel method for manufacturing iodinated resin particulates that have widespread utility as disinfectants. The invention also provides novel iodinated demand disinfectant iodinated resins that have superior properties than resins known in the art. The novel manufacturing process of the current invention is highly efficient and environmentally friendly and is conducted without the presence of water. Additionally, the manufacturing process produces iodinated resins that have better overall biological performance than resins produced by prior art methods owing to higher degrees of iodine in the manufactured resin particulates and higher degrees of uniformity of iodine content when comparing particulate to particulate.

  • Publication number: 20100316588
    Abstract: The invention relates to elastomeric products that are coated with a thin layer of elastomeric polymeric coating containing an antitoxic agent, particularly a demand disinfectant iodinated resin. The antimicrobial coated catheters are prepared by adding the antitoxic agent to a solution of a liquid elastomeric polymer and then coating the surface of the elastomeric through a dipping or spraying procedure. The antimicrobial coatings can be applied to a variety of different elastomeric products including gloves and catheters and are capable of providing a high level of protection against microbes and other contaminants.

  • Publication number: 20080102005
    Abstract: A method for disinfecting microorganisms in metalworking fluids without leaving behind unacceptable amount of chemicals in the treated fluids. The method comprises passing the fluid in a recirculating cooling system through a filter, which contains a demand disinfectant, preferably an iodinated resin. The iodinated resin inhibits the growth of microorganism in the fluid, which is then cycled back into the system. The present invention also relates to a filter and system for disinfecting microorganisms in metalworking fluids.

  • Patent number: 6184167
    Abstract: Disclosed herein are thermally stable ZSM-5 zeolite materials. The novel materials having substantially uniform micropores narrower (about 0.49 nm) or wider (about 0.55 nm and above) than those of conventional ZSM-5 zeolite (0.52-0.54 nm). Also disclosed is a preparation method (desilication/reinsertion/stabilization or DRS) for converting conventional ZSM-5 zeolite materials to the thermally stable zeolite materials of the present invention. The method of the present invention comprises the steps of sequentially treating ZSM-5 zeolite with aqueous solutions of sodium carbonate and sodium hydroxide to obtain a desilication of the zeolite, reinserting some of the silicon species (mainly sodium orthosilicate and sodium pyrosilicate) which have been selectively removed from the zeolite framework during the desilication operation, and activating the resulting materials in air or in the presence of steam at high temperatures. The amount of the reinserted silicon species depends on the pore size wanted.
