- the polyethylene terephthalate fiber provides a fabric for an air bag, characterized in that the instantaneous thermal strain is 1.0 to 5.0%.
- T 3 is the time when the steel rod heated to 450 ° C. falls through the fabric at a height of 10 cm above the fabric
- T 4 is the time when the same steel rod falls from the same height.
- the airbag fabric is characterized in that the rigidity is 5.0 to 15.0 N.
- the polyethylene terephthalate fiber is characterized in that the strength at room temperature is 8.0 to 11.0g / d, the elongation is 15% to 30%.
- the polyethylene terephthalate fiber is characterized in that the instantaneous thermal strain is 1.0 to 5.0%, single yarn fineness is 4.5 denier or less.

- the edge sewing portion is prevented from bursting in the airbag cushion development test
- a fabric for polyethylene terephthalate airbags that has improved bursting and improved airbag fabric foldability and storage.
- polyethylene terephthalate obtained by spinning a polyethylene terephthalate chip having an intrinsic viscosity (0.8) of 0.8 to 1.3 dl / g in order to safely absorb the instantaneous impact energy of the exhaust gas generated by the explosives inside the air bag.
- Polyester yarns having an intrinsic viscosity (IV) having an intrinsic viscosity of less than 0.8 dl / g are not suitable because they do not have sufficient toughness to be used as air bags.
- Resin for producing synthetic fiber multifilament for airbag includes polyethylene terephthalate, polybutylene terephthalate, polyethylene naphthalate, polybutylene naphthalate, polyethylene-1,2-bis (phenoxy) ethane-4,4 ' Copolymers comprising dicarboxylate, poly (1,4-cyclohexylene-dimethylene terephthalate) and at least one repeating unit of the polymer, for example polyethylene terephthalate / isophthalate copolyester, poly Butylene terephthalate / naphthalate copolyester, polybutylene terephthalate / decanedicarboxylate copolyester, and mixtures of two or more of the above polymers and copolymers.
- polyethylene terephthalate resin is particularly preferable in terms of mechanical properties and fiber formation.
- Polyethylene terephthalate fiber for airbags of the present invention is 8.0 to 11.0g / d at room temperature, it is preferable that the elongation is 15 to 30%.
- the strength of the polyethylene terephthalate fiber for airbags of the present invention is less than 8.0g / d, the tensile strength and tear strength of the woven airbag fabric is low, which is not suitable.
- single yarn fineness is 4.5 denier or less, and, as for the polyethylene terephthalate fiber for airbags of this invention, it is more preferable that it is 3 denier or less.
- the more the fiber of a single yarn fineness is used the softer the woven fabric will be, the more excellent the foldability and the better the storage performance.
- single yarn fineness becomes small covering property improves and, as a result, the air permeability of a fabric can be suppressed. If the single yarn fineness exceeds 4.5 deniers, the foldability and the storage performance of the fabric are deteriorated and the low air permeability is deteriorated, and thus, the airbag fabric does not have a sufficient function.
- the instantaneous heat strain in 100 degreeC is 1.0 to 5.0%, More preferably, the instantaneous heat strain is 2.0 to 4.0%. If the instantaneous thermal strain of the fiber is less than 1.0%, the energy absorbing capacity applied when the airbag cushion is inflated by the hot gas is poor, and the airbag cushion is likely to burst. In addition, when the instantaneous thermal strain of the fiber exceeds 5.0%, the increase in the length of the fiber at a high temperature causes a problem of uncontrolled expansion gas leakage due to the opening of the bar when the airbag cushion is inflated by the hot gas.
- the stiffness is preferably 5.0-15.0 N, as assessed by a circular bend measurement method, more preferably. 6.0 ⁇ 9.0N level is suitable. If the stiffness exceeds 15.0N, the fabric becomes stiff, which results in poor storage performance in manufacturing the airbag module and lowers the airbag cushion deployment performance.
- the hot rod test measured using a rod heated at 350 ° C. for uncoated polyethylene terephthalate fabrics of 50 wt. Do. If the heat resistance measured at 350 ° C. is less than 0.75 seconds, the heat resistance of the fabric for the airbag becomes too low, so that the airbag cushion does not endure high temperature gas and the sewing part of the edge is easily broken. When the heat resistance measured at 350 ° C. exceeds 1.0 second, a higher fineness polyethylene terephthalate yarn should be used, which increases the rigidity of the fabric, resulting in deterioration of module storage capacity of the airbag fabric.
- the hot rod test measured using a steel rod heated to 450 ° C. for uncoated polyethylene terephthalate fabric having 50 ton of weft yarn density per inch after scouring was preferably 0.45 to 0.65 seconds. Do. When the heat resistance measured at 450 ° C. is less than 0.45 seconds, the heat resistance of the fabric for the airbag becomes too low, so that the airbag cushion does not endure high temperature gas and the sewing part of the edge is easily broken. If the heat resistance measured at 450 ° C. exceeds 0.65 sec, a higher fineness polyethylene terephthalate yarn should be used, which increases the rigidity of the fabric, resulting in deterioration of module storage capacity of the airbag fabric.
- a woven fabric with polyethylene terephthalate fiber when weaving a woven fabric with polyethylene terephthalate fiber, it is preferable to weave a plain weave having a symmetrical structure, but to obtain a woven fabric having better physical properties, it is optional to use a yarn having a thinner linear density. You can also weave in Panama.

- the test is started 2 minutes after the stress is applied and the temperature is rapidly raised to heat for 30 seconds from 30 ° C to 100 ° C.
- the instantaneous thermal strain is expressed as a percentage by dividing the increase in sample length when the temperature reaches 100 ° C. by the initial sample length.
- the rigidity of the fabric is measured by circular bend measurement according to ASTM D4032. At this time, the inclination and weft directions are measured for each, and the average value of the warp and weft directions is expressed in Newton.
