Abstract: An apparatus for producing fibers from molten material includes a drive shaft rotatable about an axis, a slinger basket including a base, a side wall, and an interior void. The side wall extends axially upward from the base and includes a plurality of distribution holes. The interior void extends radially from the drive shaft to the side wall and extends axially from the base to an upper opening which extends radially outward from the drive shaft toward the upper flange. A spinner body is coupled with the slinger basket and includes a roof contacting and extending radially outward from the upper flange such that the upper opening is substantially unobstructed by the spinner body. A spinner side wall extends axially downward from the roof and includes a fiberizing region including a plurality of fiberizing holes provided therein.

Abstract: A fiberglass material contains glass fibers having graphite evenly distributed thereon. The graphite provides a coating that makes the fiberglass material substantially free of static electricity. Suitable graphite content of the fiberglass material is about 0.25 wt % to about 0.50 wt %, or about 0.25 wt % to about 1.0 wt %, or about 0.8 wt % of dry weight of the glass fibers. The graphite used may be synthetic material or natural material substantially free of silica. Other components of the fiberglass material may include de-dusting oil.
