Abstract
In a method for making bicomponent polymer fibers, first and second molten polymers are supplied to a rotating spinner having an orificed peripheral wall. The molten polymers are centrifuged through the orifices as molten bicomponent polymer streams. The streams are cooled to make bicomponent polymer fibers.
