본 발명은 에어백용 원단 및 그의 제조방법에 관한 것으로, 좀더 상세하게는 고강력 고신율 및 저모듈러스의 폴리에스테르 원사를 포함하여 장기간의 고온 열처리 이후에도 강인성 및 에너지 흡수 성능이 우수한 폴리에스테르 원단 및 그의 제조 방법, 이를 포함하는 차량용 에어백에 관한 것이다. 본 발명의 폴리에스테르 원단은 섬도가 300 내지 700 데니어인 폴리에스테르 원사를 포함하고, 110 ℃에서 1,000 시간 동안 열처리 후 측정한 원단의 TSRI지수가 0.85 이상이고 TERI지수가 0.80 이상을 유지함으로써, 승객에게 가해지는 충격을 최소화하여 탑승자를 안전하게 보호할 수 있다.

    PURPOSE: A fabric for an air bag and a method for fabricating the same are provided to ensure excellent shape stability, physical property, folding property, and flexibility and to safely protect passengers. CONSTITUTION: A polyester fabric contains polyester yarn of 300-700 denier. The polyester fabric has 0.85 or more of TSRI^1000 index(TSRI^1000 = TS^1/TS^0) and 0.08 or more of TERI^1000 index(TERI^1000=TE^1/TE^0). TSRI^100 indicates tensile strength retention index of a fabric measured after thermal treatment. TS^0 is tensile strength of the fabric measured at room temperature by ISO 13934-1 method. TS^1 is tensile strength of the fabric measured after thermal treatment at 110 Deg. C. for 1,000 hours. TERI^1000 indicates tensile elongation retention index of a fabric measured at 110 Deg. C. for 1,000 hours. [Reference numerals] (AA) Tensile strength(N/5cm); (BB) Room temperature(before heat aging); (CC) Heat aging(1000 hours); (DD) Heat aging(2000 hours); (EE) Heat aging(3000 hours); (FF) Embodiment 5
