Abstract
A method for making dual-glass fibers includes supplying first and second molten glass to a rotating spinner having an orificed peripheral wall, where the first glass has a higher viscosity than that of the second glass, centrifuging the first and second glasses through the orifices as molten dual-glass streams, maintaining the dual-glass streams at a temperature sufficient to enable the second glass to flow around the first glass, and cooling the dual-glass streams to make dual-glass fibers.
