Abstract
Feathered edges of fiberglass fabrics woven on a shuttleless or airjet loom are secured and prevented from ravelling by a glass yarn coated with a hot melt composition. The coated yarn is woven along the longitudinal edges of the fabric, typically in a leno weave, then heated to thermobond the adjacent glass fibers with the hot melt composition at their crossover points. A procedure for applying a hot melt to a yarn through a heated die is used.
