    • The present invention relates to a polyester yarn usable in an air bag fabric, and more specifically, to a method for manufacturing a polyester yarn, an air bag yarn manufactured therefrom, and an air bag fabric including the same, wherein the method comprises the steps of: mixing a specific dicarboxylic acid composition and glycol in a predetermined range, and performing an ester reaction; performing a polycondensation reaction for an oligomer created by said ester reaction; performing solid state polymerization for a polymer created by said polycondensation reaction; and performing melt spinning for a polyester chip created by said solid state polymerization, and performing stretching. The polyester yarn manufactured by the present invention has low modulus, high strength, and further, high contraction. In addition, the polyester yarn of the present invention obtains an excellent mechanical property with remarkably low stiffness, thereby providing a superior storage effect, shape stabilization, and an air blocking effect when used for an air bag fabric.

    • The present invention relates to a high-strength, high-extension polyester fiber to be used for anchoring, mooring, or towing a ship, and more particularly, to a polyester fiber having an elastic recovery percentage of 70% or higher at 10% deformation at the maximum load measured at room temperature, an elastic recovery percentage of 50% or higher at 20% deformation at the maximum load, and an elastic recovery percentage of 40% or higher at 30% deformation at the maximum load. The present invention also relates to a method for producing the polyester fiber and to a polyester fiber rope comprising same. The polyester fiber of the present invention comprises a filament having high strength, high extension and a high recovered-work ratio, and thus has high strength and extension properties and ensures superior mechanical properties. Therefore, the polyester fiber of the present invention may be produced into a fiber rope which can minimize yarn cutting and significantly improve shock-absorbing performance in various external conditions such as raging waves and severe ship rolling, and which has a long lifespan and ensures a high level of safety.
    • 本发明涉及一种用于锚固,系泊或牵引船舶的高强度,高延展性的聚酯纤维,更具体地说,涉及一种在10%变形时弹性回复率为70%或更高的聚酯纤维 在室温下测得的最大载荷下,最大载荷下20%变形时的弹性恢复率为50%以上,最大载荷下30%变形时的弹性恢复率为40%以上。 本发明还涉及一种聚酯纤维的制造方法和包含该聚酯纤维的聚酯纤维绳。 本发明的聚酯纤维包括具有高强度,高延伸性和高回收率的长丝,因此具有高强度和延伸性能并且确保优异的机械性能。 因此,本发明的聚酯纤维可以制造成能够使纱线切割最小化的纤维绳,并且在诸如汹涌波浪和严重的船舶滚动等各种外部条件下显着提高冲击吸收性能,并且其寿命长,并且确保 高水平的安全。
