ANTI-RAVEL AIR BAG FABRIC REINFORCEMENT

摘要

A process of reinforcing air bag fabric edges to prevent raveling or fraying of the fabric (21) during the cutting process. The process is carried out by coating the yarn crossovers with a flexible, thin film of a radiation polymerizable resin (16) and then curing the coating system at high production speeds. The air bag fabric (21, 22) is cut in those areas (25, 27, 28, 30 and 32) where the coating (16) has been applied and cured, thereby providing a band or border of cured resin of sufficient width to prevent raveling of the air bag fabric edge. The process is particularly suitable for the fabrication of air bags (1) used for the protection of vehicle occupants as in automobiles. Air bags (1) constructed of a breathable, edge-coated fabric are also described.
