Abstract
An air bag material and a process for making the material are disclosed. The air bag material is formed from a water jet woven fabric containing warp yarns and weft yarns. In accordance with the present disclosure, the warp yarns are treated with a size composition prior to being woven into the fabric. The size composition improves the runnability of the yarns. Of particular advantage, the size composition does not need to be removed after the fabric is produced. In fact, leaving the size composition on the fabric has been found to significantly increase the tear strength of the fabric.
