Abstract
A method for manufacturing a one-piece woven (OPW) air bag includes providing yarns having a spin finish and warping the yarns on at least one beam of a loom. The yarns are simultaneously woven into a fabric air bag structure having two layer portions defining an inflatable volume and single layer portions forming seams delimiting the inflatable volume. The air bag structure is coated to cover the spin finish. The coated air bag structure is cut to define the one-piece woven air bag.
