Abstract:
1. An air bag formed of two woven fabrics interwoven with each other to be a bag-shaped body, each composed of polyamide fiber yarns containing a copper compound in a mixture of a halogenated alkali metal, the copper compound selected from a group consisting of a copper salt and a halogenated copper, and having a copper concentration in the range of 30 to 200 ppm, and the polyamide fiber yarns having a total fineness in the range of from 66 decitex to 167 decitex and the yarn containing a plurality of single filaments, each filament having a fineness in the range of 1 to 3.3 decitex, wherein the product of fineness of the warp or weft of the fabric multiplied by the weave density of the fabric being not more than 16000 decitex·end or pick, respectively, /2.54 cm, the fabric having the load at 15% tensile elongation in the range of 3 to 35 N/%/2.54 cm, the tensile work at break in the range of 7000 to 30000 N·%/2.54 cm, and a value of fabric strength at break in a range from 740 to 1010 N/2.54 cm.
