The problem addressed by the present invention is to provide a polyester base fabric for an airbag, which uses polyester fibers that can be reduced in cost while maintaining the mechanical characteristics required for the base fabric for an airbag and exhibiting a high restraint performance for accommodating an occupant when deployed, and which does not exhibit a high restraint performance even if the polyester base fabric changes over time. The constraint performance remains at a high level. As a means for solving the problem, the present invention provides a polyester base fabric for an airbag, which has a resin on at least one surface, and which is characterized in that the crimp percentage of the polyester base fabric is optimized, and the number of scrubbing tests after 408-hour degradation treatment at 70 DEG C and 95% RH is 400 or more.
本发明所解决的问题是提供一种气囊用聚酯基布,所述聚酯基布使用能够降低成本的聚酯纤维,同时保持气囊用基布所需的机械特性,并且表现出在展开时容纳乘员的高约束性能,即使聚酯基布随着时间推移发生变化,所述约束性能仍保持在高水平。作为用于解决所述问题的手段,本发明提供了一种气囊用聚酯基布,所述聚酯基布在至少一个表面上具有树脂,同时其特征在于:该聚酯基布的卷曲率被优化,并且在70℃在95%RH下的408小时劣化处理后的擦洗试验次数为400以上。
