Abstract
An air bag fabric includes a warp and a weft, each including polyamide multifilaments with a total fineness of 200 to 700 dtex and a single fiber fineness of 1 to 2 dtex and having a cover factor (CF) of 1,800 to 2,300, wherein a ratio ECw/Mtw between edgecomb resistance, EDw, and single fiber fineness, Mtw, in the warp direction, and a ratio ECf/Mtf between edgecomb resistance, ECf, and single fiber fineness, Mtf, in the weft direction are both in a range of 250 to 1,000 N/dtex.

An air bag fabric comprising a warp and a weft each comprising polyamide multifilaments with a total fineness of 200 to 700 dtex and a single fiber fineness of 1 to 2 dtex and having a cover factor (CF) of 1,800 to 2,300, wherein a ratio ECw/Mtw between edgecomb resistance, ECw, and single fiber fineness, Mtw, in the warp direction, and a ratio ECf/Mtf between edgecomb resistance, ECf, and single fiber fineness, Mtf, in the weft direction are both in a range of 250 to 1,000 N/dtex.
A yarn for air bags comprising polyamide multifilament with a total fineness of 200 to 700 dtex, a single fiber fineness of 1 to 2 dtex, strength of 7 to 10 cN/dtex, and elongation of 20 to 30% said airbags having a cover factor (CF) of 1,800 to 2,300, and wherein a ratio ECw/Mtw between edgecomb resistance, ECw, and single fiber fineness, Mtw, in the warp direction, and a ratio ECf/Mtf between edgecomb resistance, ECf, and single fiber fineness, Mtf, in the weft direction are both in a range of 250 to 1,000 N/dtex.
