Abstract
In a method for producing a monofilament with reduced secondary binding forces of at least two commonly extruded polymers for the production of bristles or interdental cleaners which are slittable substantially axially through the action of mechanical forces, the at least two polymers of the monofilament are disposed in a regular geometrical arrangement with substantially axially extending boundary layers in which the reduced secondary binding forces prevail for generation of defined slits of flags.
