聚酯纤维及其制备方法
摘要：
本发明涉及一种可用于气囊织物的聚酯纤维。具体而言，本发明涉及一种聚酯纤维，该聚酯纤维在185℃热处理2分钟后在施加1.0g/d的拉伸强度时伸长率为1.65%～2.5%，并且在拉伸强度从8.0g/d到最大强度时附加伸长的伸长率在0.5%～5%的范围内。本发明还涉及所述聚酯纤维的制备方法以及由该聚酯纤维制成的气囊织物。本发明的聚酯纤维同时具有低初始杨氏模量和优异的机械特性，因此，它可以提供优异的封装性、尺寸稳定性和优异的气密效果，同时使作用到乘客上的冲击最小化，从而安全地保护乘客。
摘要（英）：

This disclosure relates to polyester fiber that can be used for an airbag fabric. Particularly, the present invention relates to a polyester fiber that has elongation of 1.65% to 2.5% when tensile strength of 1.0 g/ d is applied after heat treatment at 185 °C for 2 minutes, and additionally elongates in the range of elongation from 0.5% to 5% at the range of tensile strength from 8.0 g/d to the maximum strength. The present invention also relates to a method for preparing the same, and fabric for an airbag prepared therefrom. The polyester fiber of the present invention simultaneously has low initial Young's modulus and excellent mechanical properties, and thus, it may provide excellent packing, dimensional stability, and excellent air cut-off effect, and simultaneously, minimize impact applied to a passenger thus safely protecting a passenger.
