Title:
MATERIAL FOR CLARIFYING GAS
Document Type and Number:
WIPO Patent Application WO/2004/009217
Kind Code:
A1
Abstract:
A material for clarifying a gas which comprises a gas-permeable base material having raised hairs and a particulate adsorbing agent fixed to the surface having raised hairs; and a method for forming the material which comprises allowing a gas-permeable base material to have raised hairs, scattering a particulate adsorbing agent on the surface having raised hairs, heating the base material to melt a heat-melting polymer scattered together with the particulate adsorbing agent or a fibrous heat-melting polymer constituting the base material, to thereby fix the particulate adsorbing agent on the surface having raised hairs. The material holds an enhanced amount per unit area of the particulate adsorbing agent fixed to the base material and exhibits good pleating workability, and thus can be suitably used as a filter material for an air clarifier, an air conditioner or the like.
