Title:
AIRBAG BASE FABRIC AND PRODUCTION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2022/102790
Kind Code:
A1
Abstract:
In conventional weaving methods, the tension of warp yarns at width-direction end parts during weaving tends to be insufficient, and as a result, a difference in crimp ratio between the width-direction center and the width-direction end parts of the base fabric has been generated. The difference in crimp ratio has caused unevenness in the width direction of a woven fabric. As a solution thereto, in the present invention, the boiling water shrinkage percentage of to-be-inserted additional yarns is set to be lower than that of foundation yarns, so that shrinkage is suppressed in the width-direction end parts of the base fabric, resulting in making it possible to decrease the difference in crimp ratio between the width-direction center and the width-direction end parts of the base fabric, thereby making it possible to produce an airbag base fabric having excellent evenness in the width direction.
