Title:
METHOD FOR PRODUCING ACTIVE CARBON SHEET AND ACTIVE CARBON SHEET
Document Type and Number:
Japanese Patent JP2003064563
Kind Code:
A
Abstract:
To provide a method for producing an active carbon sheet for a chemical filter capable of removing toxic substances at a high efficiency with the least possible inhibition of adsorption activity and catalyst activity essentially possessed by active carbon.
This method is to produce the active carbon sheet comprising the active carbon and thermally fusible synthetic fibers as main constituent elements. In the method, the thermally fusible synthetic fibers are washed with a cleaning agent such as water or an organic solvent to remove an agent such as a spinning oil agent sticking to the thermally fusible synthetic fibers before introduction into a sheet-forming step. The resultant thermally fusible synthetic fibers are then used.
