Abstract
This invention involves apparatus and methods for making fibers by passing a molten material like glass, polymer, etc. through orifices or tips in a fiberizing bushing and then cooling the molten material coming from the tips and newly formed fibers with a cooling apparatus. The cooling apparatus is made from a metal to withstand the environment close beneath a fiberizing bushing and to provide the needed thermal conductivity to carry heat away rapidly. Alloys comprising nickel and titanium and that are in a martensite structure below about 200 degrees F. are used for at least parts of the cooling apparatus to reduce cost and/or provide for improved life and cooling performance and/or to improve fiberizing efficiency.
