Texturizing is a process in which a fiberglass roving (or a yarn) is subjected to an air jet that impinges on its surface to make the roving “fluffy”. The air jet causes the surface fibers to break at random, giving the roving a bulkier appearance. The extent to which this occurs can be controlled by the velocity of the air jet and the roving feed rate. The texturizing process allows the resin-to-glass ratio to be increased in the final composite part. End use applications include: fabric for welding curtains, stress-relieving blanket, compression gasketing, friction material, muffler filling and pipe insulation.
