  • Heating regeneration type organic rotor member and method for producing the same
    Patent number: 6820681
    Abstract: The object of the present invention is to provide a heating regeneration type organic rotor member which comprises a honeycomb structural body capable of being continuously regenerated by heating upon rotational driving and remarkably improved in mechanical strength by using a fiber substrate essentially composed of organic fibers and which can efficiently adsorb and remove moisture and odor components in the air by the action of moisture adsorbent and active carbon carried on the fiber substrate, and to provide a method for producing the same. According to the present invention, there is provided a heating regeneration type organic rotor member which is produced by forming a functional substrate into a honeycomb structural body, the functional substrate comprising a fiber substrate containing organic fibers as an essential component and carrying thereon a moisture adsorbent and an active carbon.

  • Photoreactive noxious substance purging agent and photoreactive noxious substance purging material using the agent
    Patent number: 5670247
    Abstract: Disclosed is a photoreactive noxious substance purging agent comprising a photoreactive semiconductor, a carrier, and a microfibrillated microfiber. In this photoreactive noxious substance purging agent, loss of the photoreaction effective surface of the photoreactive semiconductor can be held down to the minimum and a sufficient noxious substance removing characteristics can be exhibited.
