Abstract
A non-woven mat of fibrous thermoplastic insulation is produced by melt blowing recycled polyethylene teraphthalate (PET). The PET is melted, pressurized and extruded from an extrusion head into substantially continuous fibers that are subjected to turbulent high velocity air that attenuates the fibers. The fibers are then collected on a collection device building up a non-woven mat. The collection device is spaced from the extrusion device forming a flight path for the fibers that is sufficiently long that the fibers split apart under the force of the high velocity air, fibrillating into a plurality of very fine fibrils of under 15 microns in diameter. These fibrils are analogous to goose down and greatly enhance the loft and R value of the mat.
