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.

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.

A process of reinforcing airbag fabric to prevent raveling of yarns during cutting of the fabric, said process comprising the steps of: (a) applying a thin layer of coating comprising a radiation-curable, resin and at least one flame retardant to a pre-selected area of airbag fabric to be cut, said radiation-curable resin being curable and crosslinkable at substantially ambient temperatures; (b) irradiating the coated airbag fabric of step (a) in at least those areas containing the radiation-curable resin under conditions to cure and crosslink the resin into a thin, flexible, nonreactive coating impregnating the airbag fabric and securing the yarn crossovers together to prevent raveling and combout; and (c) cutting the irradiated airbag fabric in the coated areas into the pre-selected configuration, thereby producing a ravel-resistant edge.
