Abstract
Preferably configured in ridge and recess irregularity, the inventive article provides adsorption of malodor components in air and also dust collecting function. It comprises woven sheet having coarse three dimensional structure whose areas of sheet surface as well as internal fiber structure allowable to contact to incoming outer air are formed with a binder layer made of latex or emulsion or non-solvent adhesive and such binder layer is adhered with activated carbon particles partially exposed. The process of adhereing activated carbon particles is conveniently performed by a fluidizing bed. The inventive sheet form fabric incorporates the particles with a high void ratio and uniformity and thereby exhibits high adsorptive rate and capacity, and exceedingly low pressure loss with such result that it is applicable regardless of high or air wind rate. Preferable use is a filter element of air-conditioner for cars.
