This invention relates to a method for preparing glassy fibers having protuberances studded on the surface of the fiber, characterized in that each protuberance comprises an unmelted component of the starting materials and is formed on the surface of the fiber by fiberizing the partially unmelted starting materials by a spinner or blowing technique.

This invention pertains to a method of making inorganic vitreous fibers having small protrusions, such that the fiber produces a high strength reinforced molded product. The fibers are formed by introducing high melting constituents such as glass fiber, rock wool, ceramic fiber, silica particles, alumina particles, zirconia particles or mullite particles to molten inorganic material such that the constituents when flung from a ratary device are incorporated into the molten inorganic material.
