Abstract
A process of reinforcing airbag fabric edges to prevent raveling or fraying of the fabric during the cutting process. The process is carried out by coating the yarn crossovers with a flexible, thin film of a radiation polymerizable resin and then curing the coating system at high production speeds. The airbag fabric is cut in those areas where the coating has been applied and cured, thereby providing a band or border of cured resin of sufficient width to prevent raveling of the airbag fabric edge. The process is particularly suitable for the fabrication of airbags used for the protection of vehicle occupants as in automobiles. Airbags constructed of a breathable, edge-coated fabric are also described.
