Abstract

The present invention provides a splittable, multicomponent fiber or filament comprising a first polymer that has a high melting point and does not degrade in a corrosive environment, and a second polymer that has a high melting point but that is degradable in a corrosive environment. The multicomponent fiber or filament is particularly useful in filtration media.
