본 발명은 폴리에스테르 원사를 포함하는 에어백용 원단에 관한 것으로, 특히, 섬도가 400 내지 650 데니어인 폴리에스테르 원사를 포함하고, 85 ℃ 및 65 %RH 조건 하에서 4 시간 동안 열처리 후 측정한 원단의 경사방향 활탈저항력 지수(EI)가 0.15 내지 0.38인 폴리에스테르 원단 및 그의 제조 방법, 이를 포함하는 차량용 에어백에 관한 것이다. 본 발명의 에어백용 원단은 낮은 모듈러스, 고강력, 고신율의 폴리에스테르 원사를 사용하여 강인성 및 인열강도 등의 기계적 물성이 우수하고, 이와 동시에 우수한 수납성, 형태안정성, 및 공기 차단 효과를 제공하며 승객에게 가해지는 충격을 최소화하여 탑승자를 안전하게 보호할 수 있다.

    PURPOSE: Polyester fiber capable of using for airbag fabric is provided to have excellent acceptability, shape stability and air blocking ability, thereby minimizing the impact to passenger and protecting passengers safely. CONSTITUTION: Polyester fiber comprises polyester yarn with the fineness 400-650 denier. The anti-slip index(EIwa) in equation 1(EIwa= ERwa/[(weft density + warp density) × D1/2]) measured after heat treatment under the condition of 85°C and 65 %RH for 4 hours is 0.15-0.38. In equation 1, ERwa is anti-slip index(N) along weft direction measures by ASTM D 6479 method, and D is the fineness of the polyester yarn(De). The polyester fiber is coated by powder type silicon, liquid type silicon, chloroprene, neoprene rubber or emulsion type silicon resin. The manufacturing method of polyester fiber comprises a step of weaving fabric for an airbag; a step of refining the fabric; and a step of tentering the fabric.
