Abstract

A method of producing short silane-treated glass or mineral wool fibers with a very low shot content. The method comprises the steps of making a mass of the individual fibers and associated shot wherein the fiber diameters are in a prescribed range, but the fiber lengths and weight percent shot are greater than desired; putting the fiber mass and shot through a refiner to reduce the length of the fibers; subjecting the refined fibers and the shot to the action of a seperator to reduce the weight percent shot; and then reacting the separated short fibers with a silane. The resultant fibers are an effective reinforcing agent when incorporated into a general purpose resin.
