  • Patent number: 7052533
    Abstract: The invention provides a filter element exhibiting an excellent deodorizing and adsorbing function with low pressure drop, as well as to a method for its manufacture and a filter using the element. The filter element is manufactured by coating a base fabric with an adhesive and allowing the fabric to move in an electrostatic field formed by a high voltage generating device to allow pulverized adsorbent powder with a specific mean particle size and standard deviation to electrostatically adhere to the base fabric surface. The filter element can also be manufactured by dispersing a pulverized adsorbent powder on the surface of a base fabric comprising heat-fusible fibers, and then partially fusing the heat-fusible fibers by heating to attach them to the adsorbent powder and allow the adsorbent powder to adhere to the base fabric surface.

  • Publication number: 20050092675
    Abstract: The invention provides a filter element exhibiting an excellent deodorizing and adsorbing function with low pressure drop, as well as to a method for its manufacture and a filter using the element, and this is achieved by a filter element which satisfies the relationship that 0?A?1.1 mB+C and m=0.28?0.0005 D50, with the proviso that 0<C?15, where D50 (?m) is the 50% particle diameter of the adsorbent powder, B (g/m2) is the amount of the adsorbent powder adhered to the base fabric, A (Pa) is the pressure drop of the filter as measured at room temperature under an air flow rate of 1 m/sec and C (Pa) is the pressure drop of the base fabric when coated with the adhesive and dried, as well as a method for its manufacture and a filter using the element.
