Abstract

PURPOSE: To provide an adsorbing filter-sheet having harmful gas rmoving ability and of low head loss, by providing penetrated holes of prescribed opening ratio to a cloth-formed matter of activated carbon fibers having a specified head loss constant and a specified bezene adsorbing rate constant.
CONSTITUTION: A cloth-formed matter of activated carbon fibers having the head loss constant ranging 0.03W13 and ≥0.2/sec benzene adsorbing rate constant is prepared. The matter is produced by a carbonizing activation of precursory organic fibers such as cellulose, PAN in the atmosphere of combustion gas containing such as inert gas. Next, one or plural penetrating holes having the opening ratio made to be 0.001W0.5 are provided to the matter, and needle punching is also applied to the matter to obtain a desired adsorbing filter-sheet. Said penetrated holes are usually punched in the size ranging 5W10mm, and that is suitable. The filter sheet is suitable for a room purifying device and an air conditioner in a car room, etc. Further, the sheet has especially the adsorbing rate of 100W1,000 times as much as an ordinary activated carbon.
