However, the existing use of polyester fibers in the manufacture of airbags has made it difficult to install the airbags in the narrow space inside the car due to its extremely high stiffness, and has caused difficulties in the high-temperature heat treatment process due to its high elasticity and low elongation. Excessive thermal shrinkage, and limitations in maintaining good mechanical properties and unfolding properties under harsh conditions of high temperature and high humidity

[0098] PET chips with a defined intrinsic viscosity are processed into polyester fibers in one step by means of a melt spinning machine. The above-mentioned polyester fiber was woven into a green fabric for an airbag by a rapier loom, and washed and tentered to obtain an airbag fabric.
[0099] In this regard, Table 1 shows the intrinsic viscosity, CEG content, melt spinning temperature, draw ratio and heat treatment temperature of PET chips; fiber properties such as tenacity, tear strength, tensile strength and heat capacity of fusion (ΔH); weaving density of warp and weft yarns, weaving type, heat treatment temperature, rubber composition and coating weight of the fabric. Other conditions are as known in the prior art related to the preparation of polyester fabrics for airbags.

Abstract
The present invention relates to a fabric for an airbag which includes polyester fiber, and particularly, to a polyester fabric, the heat resistant constant (x) of which is 1.0 to 6.5 in an uncoated fabric state, to a method for manufacturing the polyester fabric, and to an automotive airbag including the polyester fabric. The fabric of the present invention for an airbag provides good mechanical properties such as high tenacity and high heat resistance, and excellent storability, shape stability and air blocking ability by using a polyester yarn having a low modulus, high strength and high elongation, and minimizes impacts applied to a passenger, thereby enabling the passenger to be safely protected.
Description
technical field [0001] The present invention relates to an airbag fabric and a preparation method thereof, and more particularly to a polyester fabric, a preparation method thereof, an airbag for automobiles comprising the polyester fabric, wherein the polyester fabric is used with a low Young's Modulus, high strength and high elongation polyester fibers to impart good mechanical properties (such as high strength and excellent heat resistance). Background technique [0002] Generally speaking, an airbag is a frontal collision of a car at an impact rate of about 40km / h or more. After the impact sensor detects the impact, it uses explosive chemicals to generate gas and inflate the airbag cushion to protect the occupants. car safety device. The structure of the conventional airbag system is as follows: figure 1 Illustrated. [0003] Such as figure 1 As shown, the conventional airbag system includes: an airbag module 100, which is installed in the steering wheel and includes...
