Abstract
Official abstract text for this publication.
A coated base fabric for an airbag has a fabric composed of polyamide fibers provided with a resin coating, wherein the polyamide fibers which compose the base fabric have a total fineness of not less than 100 dtex and not more than 250 dtex and a tenacity of not less than 8.1 cN/dtex and the coated base fabric has a basis weight of not more than 170 g/m2, packability of the base fabric in accordance with ASTM D6478-02 of not more than 1,400 cm3, a tear strength in a warp direction and a weft direction of not less than 200 N and an edgecomb resistance in the warp direction and the weft direction of not less than 200 N.
First claim
Opening claim text (preview).
The invention claimed is: 1. A coated base fabric for an airbag in which a fabric composed of polyamide fibers is provided with a resin coating, wherein the polyamide fibers composing the base fabric have a total fineness of not less than 100 dtex and not more than 250 dtex and a tenacity of not less than 8.1 cN/dtex, and the coated base fabric for airbag has a basis weight of not more than 170 g/m 2 , packability of the base fabric in accordance with ASTM D6478-02 of not more than 1,400 cm 3 , a tear strength in a warp direction and a weft direction of not less than 200 N, and an edgecomb resistance in the warp direction and the weft direction of not less than 200 N. 2. The coated base fabric of claim 1 , wherein tenacity of the polyamide fibers is not less than 9.0 cN/dtex. 3. The coated base fabric of claim 1 , wherein a coating weight of the resin is 5 to 20 g/m 2 . 4. The coated base fabric of claim 1 , wherein a single fiber fineness of the polyamide fibers is 1 to 4 dtex. 5. An airbag produced by sewing the coated base fabric of claim 1 . 6. A method of producing the coated base fabric of claim 1 , comprising performing weaving by adjusting warp tension to 30 to 70 cN/end and shedding timing in weaving to 330 to 340 degrees. 7. The coated base fabric of claim 2 , wherein a coating weight of the resin is 5 to 20 g/m 2 . 8. The coated base fabric of claim 2 , wherein a single fiber fineness of the polyamide fibers is 1 to 4 dtex.
