Zusammenfassung:A method of making a spinner disc for a rotary fiberization process includes: forming a spinner disc from an alloy that forms a protective oxide film on surfaces of the spinner disc exposed to the atmosphere; forming fiberizing holes in an annular peripheral sidewall of the spinner disc; and applying a plasma to a surface of the spinner disc to remove hydrocarbons and sulfurous compounds from the surface of the spinner disc which would otherwise reduce and/or react with and degrade the protective oxide film forming on the surface of the spinner disc when the spinner disc is exposed to the atmosphere.
