Polyester fibers for airbags having an impact resistance of 0 or more and a knot strength of 4.1 g / d or more have been proposed. All of these fibers have a compressive stress (about 22 kg / mm) in the fiber cross-sectional direction. 2 ) Large energy absorption due to deformation in the cross-section of the fiber is small. For this reason, in the case of using a non-coated airbag base fabric, there is a problem that the base fabric weight is increased and the storage property is reduced if it is attempted to simultaneously satisfy the ventilation prevention property and the impact resistance.

In other words, it is important to suppress the crystallization of the fiber surface by using a non-contact type heat source for the heat drawing and relaxation heat treatment. It is presumed that the crystallization of the portion proceeds, and it is impossible to obtain a fiber having a low sectional compressive stress.
