DEODORIZING FILTER MATERIAL

摘要

A deodorizing filter material characterized by comprising a pair of two-dimensional reticular skeletons disposed parallel and spaced a predetermined distance apart from each other, a limitless number of connecting threads which connect the pair of two-dimensional reticular skeletons to form a three-dimensional fiber skeleton, to which a deodorant is adhered, the deodorizing filter material having excellent deodorizing performance superior to one using a polyurethane foam matrix, without producing problems such as those concerning construction, production, and strength, and by reason of the same laminar flow effect as in the case of using a matrix of honeycomb construction. Further, a renewable deodorizing filter material characterized in that a deodorant having a gas adsorbing action due to ion exchange function is adhered to the skeleton surface of a filter matrix of three-dimensional construction makes it possible to recycle filters whose deodorizing performance has degraded.
