ABSTRACT OF THE DISCLOSURE Disclosed is a fiber obtained by at least partially fibrillating or splitting a composite fiber having an islands-in- sea construction comprising a plurality of island components which are separated from and parallel to each other in the axial direction of the composite fiber and are surrounded by a sea component, wherein the sea component is made of an ion exchange resin and the island components are made of a reinforcing polymer which is not an ion exchanger. Also disclosed is a sheet composed of such a fiber. The fibrous resin is particularly useful in tobacco filters which may selectively reduce ionic, polar and mutagenic components as well as tar and nicotine in tobacco smoke.
