Abstract
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.
