Abstract
A method for forming an airbag fabric for use in protecting vehicle occupants during a collision. The airbag fabric includes at least a portion of fabric woven by water-jet weaving yarns without chemical sizing compounds thereon at weave constructions comparable to those available by traditional Rapier weaving processes.
Claims8
A method for water-jet weaving a high weave density fabric for use in a vehicle airbag, the method comprising the steps of:
- (a) conveying a plurality of warp yarns having a denier of about 630 or greater with no chemical sizing compound thereon through a water-jet weaving machine;
- (b) inserting a plurality of fill yarns having a denier of about 630 or greater with no chemical sizing compound thereon between said plurality of warp yarns by means of a water-jet such that any yarn oils are at least partially removed by said water jet;
- and
- (c) beating said plurality of fill yarns into place between said warp yarns such that a fabric having a weave density of about 39 threads per inch or greater is produced.

A method for water-jet weaving a high weave density fabric for use in a vehicle airbag, the method comprising the steps of:
- (a) conveying a plurality of warp yarns having a denier of about 840 or greater with no chemical sizing compound thereon through a water-jet weaving machine;
- (b) inserting a plurality of fill yarns having a denier of between about 840 or greater with no chemical sizing compound thereon between said plurality of warp yarns by means of a water-jet such that any yarn oils are at least partially removed by said water jet;
- and
- (c) beating said plurality of fill yarns into place between said warp yarns such that a fabric having a weave density of about 34 threads per inch or greater is produced.
