<p>Provided are an airbag fabric superior both in low air permeability and compactness in packing that are needed for airbag fabrics and also in edgecomb resistance that can reduce the yarn displacement in the sewn region of the fabric, an airbag prepared by using the same, and a production method thereof.
An airbag fabric consisting of warp and weft yarns of the synthetic fiber yarn, characterized by satisfying the following requirements:
(1) the total fineness of the synthetic fiber yarn is 100 to 700 dtex;
(2) Nf/Nw ‰¥ 1.10
wherein,
Nw represents the weaving density of warp yarns (yarns/2.54 cm) and
Nf represents the weaving density of weft yarns (yarns/2.54 cm);
(3) EC1 ‰¥ 400N and EC2 ‰¥ 400N
wherein,
EC1 represents the edgecomb resistance (N) in the machine direction, as determined according to ASTM D6479-02, and
EC2 represents the edgecomb resistance (N) in the crosswise direction as determiend according to ASTM D6479-02;
(4) 0.85 ‰¤ EC2/EC1 ‰¤ 1.15; and
(5) the air permeability, as determined according to the Frajour type method specified in JIS L1096 at a test pressure difference of 19.6 kPa, is 1.0 L/cm 2 ·min or less.</p> |
