Embodiment 1

[0084] (silk preparation)

[0085] As the warp and weft, prepare polyester, have a circular cross-sectional shape, consist of 96 single fibers (5.83 dtex 96F) with a single fiber fineness of 5.83 dtex, a total fineness of 560 dtex, and a tensile strength of 7.5 cN / dtex, 21% elongation, untwisted synthetic fiber filament.

[0086] (making of warping and weaving beams)

[0087] Above-mentioned silk is used as warp yarn, in warping machine, the tension of warping sheet yarn is adjusted to 50g / root, and in shaft warping machine, the tension of shaft warping sheet yarn is adjusted to 75g / root, and warp yarn weaving is made. axis.

[0088] (weaving)

[0089]Using the above-mentioned warp yarn beam and the weft yarn composed of the above-mentioned filaments, weaving is carried out by a loom equipped with a positive warp loosening mechanism (KK Toyoda Automatic Loom Water Jet Loom LWT710), and the weaving density of the obtained warp yarn is 46 / 2.54cm, weft yarn weaving density...

Embodiment 2

[0095] Change the coating amount of the resin to 18g / m 2 , except that, the base fabric was obtained by the same method as in Example 1. Table 1 shows the properties of the obtained base fabric.

Embodiment 3

[0097] In the weaving process, the amount of pine is changed to 4.8mm, and the amount of resin coating is changed to 28g / m 2 , except that, the base fabric was obtained by the same method as in Example 1. Table 1 shows the properties of the obtained base fabric.

Abstract

The present invention relates to a polyester base fabric for airbags, which is a polyester base fabric for airbags woven from polyester fibers, which is stretched to a stress of 118N / cm and then relaxed to When the stress is 0N / cm, the energy absorption in the warp direction and the weft direction is 1.0-3.0J / cm2, and the ratio of the energy absorption in the warp direction to the energy absorption in the weft direction is 0.5-2.0.

Description

technical field [0001] The present invention relates to a polyester base fabric for an airbag, a polyester airbag, and a method for producing a polyester base fabric for an airbag. More specifically, the present invention relates to a polyester base fabric for an airbag capable of producing an airbag that maintains the mechanical properties of the airbag and has improved restraint performance against passengers during deployment, and a polyester base fabric for sewing the airbag. A polyester airbag obtained from an ester base fabric and a method for producing a polyester base fabric for an airbag. Background technique [0002] In recent years, various airbags have been installed in automobiles as passenger safety protection devices of automobiles. Examples of various airbags include a driver's seat, a passenger's seat, a thigh protection built in a passenger seat, and a curtain airbag deployed along a side window. As a base fabric constituting an airbag, a base fabric made...
