摘要： An active force electric field anti-pathogenic fabric is used to remove pathogens from an environment surrounding the fabric. The fabric can be woven into daily clothing items, personal protective equipment, or other clothing items typically worn by a user. The fabric includes a current-carrying mesh that is coated with active materials used to remove pathogens from the air. As such, the fabric operates as an anti-pathogenic material that is used to remove harmful particles from an area surrounding a user. Accordingly, microorganisms, smoke particles, industrial pollutants, odor molecules, allergens are structurally disassociated into harmless protein fragments and natural molecules when encountering the purifying agents in the fabric.

摘要： An antibacterial filter, a method for manufacturing the filter, and an air purifier comprising the filter. The antibacterial filter contains a specific range of active copper particles bound to the surface of fibers, and thus can effectively prevent microorganisms, such as bacteria, fungi, and viruses, harmful to the human body, from proliferating on or contaminating the filter surface, and further improve antibacterial performance and sustained antibacterial performance. Additionally, when the antimicrobial filter is applied to an air purifier, it is possible to supply purified air and, at the same time, further improve the durability and lifetime characteristics of the filter.

摘要： A system and method of forming fiberglass air filtration media is disclosed which does not require the use of oil additives. A mixture of resin binder, polymer, and dry adhering agent is formed and applied to the fiberglass as it spins onto the drum. Additionally, the fiberglass filtration media density can vary such that the fiber on the air inflow is less dense than the fiber on the air outflow. After oven curing, the finished air filtration media has an improved ability to attract and hold dust and other contaminants.

摘要： A method of bonding a nanofiber web of nanofibers having diameters of between about 50 nanometers and about 2,000 nanometers onto a surface of a woven or nonwoven polymeric media having media fiber diameters of between about 700 nanometers and about 50,000 nanometers utilizes exposing the topmost layer of nanofibers and media fibers to a jet of heated air for a time and at a distance such that substantially only the topmost layer of fibers are bonded. The jet of heated air exits through a nozzle slot having a length of less than about 2 inches in the nanofiber web travel direction. The temperature of the heated air ranges from about 2 to about 10 times the nanofiber melting temperature, and heat air has a nozzle slot velocity of greater than about 500 feet/minute. An adhesive may bond the nanofibers, to a media, which may be bi-component fiber fibers.

摘要： The present invention relates to a composition, textile, and mask for reducing the inhalation of pollutants. The composition includes an aqueous solution of an inorganic iodide compound, a metal phthalocyanine, and a polymeric binder. The inorganic iodide can be cuprous iodide, the metal phthalocyanine can be iron phthalocyanine, and the polymeric binder can be polyvinylpyrrolidone or polyvinyl alcohol. This pollutant-inactivating composition neutralizes pollutants such as nitrogen dioxide, sulfur dioxide, ozone, volatile organic compounds and other unpleasant airborne agents, without requiring elevated temperatures or bulky canisters containing adsorbents. Optionally, a humectant can also be incorporated into the coating solution to retain moisture in the active filter matrix, which enhances the activity of the composition to inactivate oxidizing gases and other toxic constituents of air pollution.

摘要： Disclosed herein is a method of producing a filter medium for treating medium and high temperature exhaust gas using foam coating and a filter medium produced using the method. The filter medium has excellent heat resistance and heat contraction resistance, and exhibits partial dust collection efficiency of 99% or more by weight, total dust collection efficiency of 99.999% or more by weight, and high dust removal efficiency, for all dust particle sizes. Further, the filter media can be efficiently used to treat medium and high temperature exhaust gas because pores having an average pore size of 30 μm or less are uniformly distributed on the surface of the filter media.
