Articles can be provided with odor resistance by applying a dispersion of a halogenated heterocyclic N-halamine in an inert liquid carrier onto the surface of the article and allowing the inert liquid carrier to penetrate into it. The N-halamine accordingly becomes deposited on the surface of the article after the inert liquid carrier penetrates into the article. This method can be used to provide odor resistance to a variety of substrates, including garbage bags. It can also be used to deposit other functional particulates onto the surface of substrates having sufficient porosity to take up the vehicle. For instance, such functional particles can be oxidants that display antimicrobial and/or enzyme inhibitory efficacy or particles having toxin interaction potentials through oxidative degradation or adsorption of toxic substances in air and/or water, such as fluoride uptake by metal oxide microparticles.
A method for manufacturing a medium for purifying fluids which comprises applying a dispersion of a micronized metal oxide in an inert liquid carrier to the surface of a substrate having a high surface area and allowing the inert liquid carrier to penetrate into the substrate leaving the micronized metal oxide stranded on the surface of the substrate.
A method for manufacturing a medium for purifying fluids containing toxic compounds which comprises applying a dispersion of a halogenated heterocyclic N-halamine in an inert liquid carrier to the surface of a substrate having a high surface area and allowing the inert liquid carrier to penetrate into the substrate, wherein the inert liquid carried does not react with halogen atoms in the halogenated heterocyclic N-halamine, wherein the halogenated heterocyclic N-halamine is capable of destroying the toxic compound by oxidative action, and wherein the halogenated heterocyclic N-halamine becomes deposited on the surface of the substrate after the inert liquid carrier penetrates into the substrate.
A deodorizing solution which is comprised of an organic liquid and a halogenated heterocyclic N-halamine, wherein the organic liquid does not react with halogen atoms in the halogenated heterocyclic N-halamine, and wherein the halogenated heterocyclic N-halamine is soluble with the organic liquid.
A highly efficient air filter which is comprised of an air filtration medium which has been treated with a dispersion of a halogenated heterocyclic N-halamine in an inert liquid carrier.
An air filter which is comprised of an air filtration medium having particles of a halogenated heterocyclic N-halamine deposited on the surface thereof.
