摘要:
A polyester fiber that can be used for an airbag fabric is disclosed. The polyester fiber has an 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 polyester fiber 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.

摘要:
Disclosed is a inflatable double-layered fabric. The fabric includes an inflating part having gas inflatability, a non-inflating part supporting the inflating part, and a co-woven part constituting a boundary between the inflating part and the non-inflating part, wherein the inflating part is composed of two separated fabric layers, and the weave of the co-woven part is set up at a nk+1 pixel from the width or length end of the double-layered fabric (where, k is 2 or 3, and n is 0 or a positive number) when dividing the double-layered fabric into a plurality of pixels, an airbag including the same, and a method of preparing the airbag.
