POLYESTER FABRIC FOR AN AIRBAG, AND METHOD FOR MANUFACTURING SAME

摘要

The present invention relates to a fabric for an airbag including a polyester fiber, and particularly to a polyester fabric for an airbag of which toughness is 3.5 to 6.0 kJ/ m 3 and tearing strength measured according to the ASTM D 2261 TONGUE method is 18 to 30 kgf, wherein the fabric includes polyester fiber of which toughness is 70 to 95 J/m 3 , a method of preparing the same, and an airbag for a car including the same. The fabric for an airbag of the present invention is superior in energy absorbing ability and shape stability when the airbag expands, and also provides superior packing properties and air-tightness and can protect occupants safely by minimizing the impact applied to the occupants, by optimizing toughness and tearing strength of the fabric by using the polyester fiber having low modulus, high strength, and high elongation.
