Abstract
A technical problem to be solved by the present invention is to provide a non-coated fabric for airbags and a coated fabric for airbags that are both less likely to have yarn slippage after being sewn, and that can be compactly stored; and airbags using these fabrics. The fabric for airbags according to the present invention is a non-coated fabric for airbags or a coated fabric for airbags that both have a crimp ratio of 12% or more in the warp direction, and a crimp ratio of 61 or less in the weft direction.
Claims12
A non-coated fabric for airbags having a crimp ratio of 12% or more in the warp direction and a crimp ratio of 6% or less in the weft direction;
- wherein the non-coated fabric is a base fabric of a side-curtain airbag, and the non-coated fabric has an edgecomb resistance of 1500 N or more in the warp yarn direction based on two layers of the non-coated fabric.
A coated fabric for airbags having a crimp ratio of 12% or more in the warp direction and a crimp ratio of 6% or less in the weft direction;
- wherein the coated fabric is a base fabric of a side-curtain airbag, and the coated fabric has an edgecomb resistance of 1600 N or more in the warp yarn direction based on two layers of the non-coated fabric.
A non-coated fabric for airbags having a crimp ratio of 12% or more in the warp direction and a crimp ratio of 6% or less in the weft direction;
- wherein the non-coated fabric is a base fabric of a side-curtain airbag, and the non-coated fabric has a weaving density of 56 yarn threads/2.54 cm or more in both the weft direction and the warp direction.
