Title:
ACTIVATED CARBON FIBER FILTER AND ITS PRODUCTION
Document Type and Number:
Japanese Patent JP2000005543
Kind Code:
A
Abstract:

To reduce air resistance while increasing adsorption by constituting a filter used for removing a gas in the air so that an activated carbon fiber is provided in a fluffed state on a base cloth having a mesh-like structure.

The base cloth 1 having the mesh-like structure is formed by connecting warp 2 and weft 3 in zigzag and the mesh (void) 4 is formed into a hexagonal structure. The activated carbon fiber filter is produced by providing the activated carbon fiber 5 in the fluffed state on the warp 2 of the base cloth 1. The activated carbon fiber 5 can be formed from a multifilament forming a loop. The mesh (void) 4 of the base cloth 1 is preferably made large to reduce the pressure drop and is preferably ≥2 mm2. The activated carbon fiber 5 is provided on one surface of the base cloth 1 and also can be provided on both surfaces. And the activated fiber filter is manufactured by providing a fiber on the base cloth 1 preferably having the mesh like structure in the fluffed state and next, carbonizing and activating.
