<p>PURPOSE:To remove harmful gas, fine particles, etc., in an outside air to be introduced into a car or in air in a car by mounting on a car an air filter obtd. by radiation graft polymn. of monomers having ion exchanging groups to woven fabric or the like made of ion exchange fiber consisting of a polyolefin, etc., as the base body. CONSTITUTION:An air filter 5 is produced by radiation graft polymn. of monomers having ion exchanging groups to woven fabric or nonwoven fabric made of ion exchange fiber consisting of a polyolefin, etc., as the base body. Or the air filter 5 is produced by radiation graft polymn. of monomers to which ion exchanging groups can be easily introduced and then introducing ion exchange groups thereto. The ion exchange groups are sulfo groups, phosphoric acid groups or carboxyl groups as cation exchange groups, or quaternary ammoium, tertiary amines, secondary amines or primary amines as anion exchange groups. By mounting this filter 5 on a sucking entrance for outside air or the like of a car, harmful gas, odor, fine particles, etc., in air of in the car can be removed.</p> |
