Definitions
- the present invention relates to a polyethylene terephthalate fiber for air bags and a textile for air bags made from the same, and, more particularly, to a textile for air bags having an improved rupture property at a sewn welt portion so that a polyethylene terephthalate multifilament made by spinning polyethylene terephthalate chips having an intrinsic viscosity of 0.8 to 1.3 can be prevented from rupturing in an air bag cushion deployment test when the polyethylene terephthalate multifilament is applied to the textile for air bags by adjusting a strength/deformation curve of the polyethylene terephthalate multifilament.
- a textile for air bags requires a variety of characteristics such as low poromericity to smoothly deploy an air bag upon collision, high energy absorption capability to prevent damage/breakage of an air bag itself, and foldability for a textile itself to improve storage.
- a Nylon 66 material has been widely used as a fiber that is suitable for the requirements of such an air bag textile. In recent years, increasing attention has been paid to fiber materials rather than Nylon 66 due to their economic efficiency, for example, cost savings, etc.
- the present invention is directed to providing a textile for air bags made from a polyethylene terephthalate fiber having an improved rupture property at a sewn welt portion so that a polyethylene terephthalate multifilament can be prevented from rupturing in an air bag cushion deployment test by adjusting a strength/deformation curve of the polyethylene terephthalate multifilament.
- One aspect of the present invention provides a polyethylene terephthalate multifilament for air bags made by spinning polyethylene terephthalate chips having an intrinsic viscosity of 0.8 to 1.3.
- the polyethylene terephthalate multifilament for air bags is characterized in that it has a strength/deformation curve in which the polyethylene terephthalate multifilament extends by less than 4% when subjected to an initial stress of 1.0 g/d at room temperature, extends by less than 12% when subjected to a medium stress of 4.5 g/d and extends by 3% or more until fibers are cut at a tensile strength of at least 7.0 g/d, and has an elongation at break of 15% or more and a single fiber thickness of 5 deniers or less.
- the polyethylene terephthalate multifilament has a value of 1.5 or more, in case which is calculated by dividing an F/F coefficient of kinetic friction of a yarn by an F/M coefficient of kinetic friction of the yarn.
- the polyethylene terephthalate multifilament has a carboxyl end group (CEG) content of 35 mmol/kg or less.
- the polyethylene terephthalate multifilament has a maximum thermal stress of 0.2 to 0.5 g/d.
- the polyethylene terephthalate multifilament has a total fiber thickness of 150 to 1,000 deniers.
- the textile for air bags is prepared by coating the textile for air bags with one coating agent selected from the group consisting of a silicon-based coating agent, a polyurethane-based coating agent, an acrylic coating agent, a neoprene-based coating agent and a chloroprene-based coating agent at a content of 15 to 60 g/m 2 .
- one coating agent selected from the group consisting of a silicon-based coating agent, a polyurethane-based coating agent, an acrylic coating agent, a neoprene-based coating agent and a chloroprene-based coating agent at a content of 15 to 60 g/m 2 .
- a textile for air bags having an improved rupture property at a welt portion in an air bag cushion deployment test can be prepared using a polyethylene terephthalate fiber that can be prepared from the polyethylene terephthalate multifilament.
- the polyethylene terephthalate multifilament has a strength/deformation curve in which the polyethylene terephthalate fiber extends by less than 4% when subjected to an initial stress of 1.0 g/d at room temperature, extends by less than 12% subjected to a medium stress of 4.5 g/d and extends by 3% or more until fibers are cut at a tensile strength of at least 7.0 g/d, and has an elongation at break of 15% or more, a value of 1.5 or more, in case which is obtained by dividing an F/F coefficient of kinetic friction of a yarn by an F/M coefficient of kinetic friction of the yarn, a carboxyl end group (CEG) content of 35 mmol/kg or less, and
- CEG carboxy
- first, second, etc. may be used to describe various elements, these elements are not limited by these terms. These terms are only used to distinguish one element from another. For example, a first element could be termed a second element, and, similarly, a second element could be termed a first element, without departing from the scope of exemplary embodiments.
- the term “and/or” includes any and all combinations of one or more of the associated listed items.
- the present invention is directed to providing a textile for air bags having an improved rupture property at a sewn welt portion so that a polyethylene terephthalate multifilament made by spinning polyethylene terephthalate chips having an intrinsic viscosity of 0.8 to 1.3 can be prevented from rupturing in an air bag cushion deployment test when the polyethylene terephthalate multifilament is applied to the textile for air bags by adjusting a strength/deformation curve of the polyethylene terephthalate multifilament.
- a polyethylene terephthalate multifilament obtained by spinning polyethylene terephthalate chips having an intrinsic viscosity (IV) of 0.8 to 1.3 is used in the present invention.
- a polyester yarn in which a resin has an intrinsic viscosity of less than 0.8 dl/g is not desirable since the polyester yarn does not have sufficient toughness.
- a resin used to form a multifilament for air bags according to the present invention may include polybutylene terephthalate, polyethylene terephthalate, polybutylene naphthalate, polyethylene-1,2-bis(phenoxy)ethane-4,4′-dicarboxylate, poly(1,4-cyclohexylene-dimethylene terephthalate) and a copolymer including the polymer as one or more repeating unit.
- the resin may be selected from the group consisting of polyethylene terephthalate/isophthalate copolyester, polybutylene terephthalate/naphthalate copolyester, polybutylene terephthalate/decanedicarboxylate copolyester, and a mixture of at least two of the polymers and copolymers.
- a polyethylene terephthalate resin is particularly preferably used in the present invention due to its mechanical properties and fiber formation characteristics.
- the polyethylene terephthalate fiber according to the present invention may have a carboxyl end group (CEG) content of 35 mmol/kg or less.
- CEG carboxyl end group
- a fiber suitable for use as the polyethylene terephthalate multifilament for air bags according to the present invention may extend by less than 4% when the fiber is subjected to an initial stress of 1.0 g/d in a strength/deformation curve.
- the polyethylene terephthalate multifilament extends by 4% or more at an initial stress of 1.0 g/d, a textile may be suddenly deformed and damaged at the beginning.
- the filament when a filament is subjected to a medium stress of 4.5 g/d, the filament may extend by less than 12%. When the filament extends by 12% or more at a medium stress of 4.5 g/d, a human body may get burned by an exhaust gas due to a sudden increase in poromeric degree of the textile.
- the textile made from the polyethylene terephthalate multifilament may extend by 3% or more until fibers are cut at a tensile strength of at least 7.0 g/d, so as to allow the textile to have a tensile strength and a tear strength which are suitable for use as an air bag.
- This is problematic because, when the textile extends by less than 3% until the fibers are cut at a tensile strength of at least 7.0 g/d, a maximum capability of the fibers to absorb a tensile load is insufficient.
- the tensile strength and tear strength of the fibers may not be sufficient.
- the polyethylene terephthalate multifilament for air bags may have an elongation at break of 15% or more.
- the elongation at break of the multifilament is less than 15%, an energy absorption capability when an air bag cushion suddenly expands may be degraded, and thus the cushion may burst.
- the polyethylene terephthalate multifilament for air bags may have a maximum thermal stress of 0.2 to 0.6 g/d.
- a yarn may have an insufficient strength under conditions for production of yarn having a maximum thermal stress of less than 0.2 g/d, whereas the yarn may have a low elongation under conditions for production of yarn having a maximum thermal stress greater than 0.6 g/d.
- the air bag cushion may easily burst in the air bag cushion deployment test.
- the polyethylene terephthalate multifilament for air bags may preferably have a total fiber thickness of 150 to 1,000 deniers, more preferably 200 to 700 deniers.
- the textile for air bags may be insufficient in storage, but an air bag may be broken as a passenger collides against the air bag during or after deployment of the air bag.
- the total fiber thickness exceeds 1,000 deniers, the safety of the air bag may be satisfied due to sufficient strength thereof, but the storage of the air bag may be reduced due to an increase in thickness of the textile.
- the multifilament constituting the textile for air bags may preferably have a single fiber thickness of 5 deniers or less, more preferably 4.5 deniers or less.
- a single fiber thickness of 5 deniers or less, more preferably 4.5 deniers or less.
- the resulting textile is flexible, and thus has excellent foldability and good storage.
- a covering property may be improved as the single fiber thickness decreases.
- the single fiber thickness exceeds 5 deniers, the foldability and storage of the textile may be reduced, and the low poromericity may also be degraded. Therefore, the textile may not sufficiently function as the textile for air bags.
- a ratio of an F/F friction coefficient means a value obtained by dividing a coefficient of kinetic friction (F/F ⁇ s) between fibers of a polyethylene terephthalate yarn by a coefficient of kinetic friction (F/M ⁇ s) between fibers and metal.
- the ratio of the F/F friction coefficient is preferably 1.5 or more. More preferably, a yarn whose ratio of the F/F friction coefficient is 2.0 or more may be suitably used for the textile for air bags.
- the ratio of the F/F friction coefficient is less than 1.5, a friction coefficient between the fibers is insufficient, and thus a sewn welt portion may increasingly rupture in the air bag cushion deployment test.
- a polyethylene terephthalate yarn for air bags may be prepared by spinning a spinning emulsion, which is selected from the emulsion types of spinning emulsions, at an OPU attachment content of 0.6%.
- the polyethylene terephthalate fiber prepared by the preparation method according to the present invention may be obtained using an air jet or water jet loom weaving machine. However, since a residual oil in the textile has to be present at a content of 0.1% by weight or less, the polyethylene terephthalate fiber may be prepared using the water jet loom weaving machine in consideration of the detachability of an emulsion attached to fibers. Also, the woven fiber may be subjected to a refining process and thermal setting at 160 to 190° C.
- a textile When a textile is woven from the polyethylene terephthalate fiber prepared by the preparation method according to the present invention, it is desirable to weave a plain fabric having a symmetrical structure.
- a filament having a lower linear density may be woven from a 2/2 Panama woven fabric having a symmetrical structure.
- the woven textile may be coated with a coating agent selected from the group consisting of a silicon-based coating agent, a polyurethane-based coating agent, an acrylic coating agent, a neoprene-based coating agent and a chloroprene-based coating agent at a content of 15 to 60 g/m 2 , and used to secure the low poromericity that is suitable for use in the textile for air bags.
- a coating agent selected from the group consisting of a silicon-based coating agent, a polyurethane-based coating agent, an acrylic coating agent, a neoprene-based coating agent and a chloroprene-based coating agent at a content of 15 to 60 g/m 2 , and used to secure the low poromericity that is suitable for use in the textile for air bags.
- 0.1 g of a test sample is dissolved for 90 minutes in a reagent (90° C.) obtained by mixing phenol with 1,1,2,2-tetrachloroethanol at a weight ratio of 6:4. Thereafter, the resulting sample solution is transferred to an Ubbelohde viscometer, and kept at 30° C. for 10 minutes in a thermostat. Then, a dipping time (second) of the sample solution is calculated using a viscometer and an aspirator. Also, a dipping time (second) of the solvent is obtained in the same manner as described above. Then, an R.V. value and an I.V. value are calculated using the following equations.
- R.V. dipping time (second) of test sample/dipping time (second) of solvent
- I.V. 1/4 ⁇ [(R.V. ⁇ 1)/ C ]+3/4 ⁇ (In R.V./ C )
- C represents a concentration (g/100 ml) of the test sample in the sample solution.
- a yarn is prepared into a loop having a diameter of 10 cm using a thermal stress tester (Model name: KE-3LS commercially available from KANEBO), and hung on upper/lower end hooks. Then, an initial load of 0.05 g/den is applied to the test sample, and the test sample is heated at a rate of 2.2° C./second. In this case, stress caused in the test sample is measured and plotted as a graph.
- a thermal stress tester Model name: KE-3LS commercially available from KANEBO
- a CEG content is analyzed using a test method “GG7” ((Geosynthetic Research Institute (GRI)), and indicated by units of mmol/kg.
- GG7 (Geosynthetic Research Institute (GRI))
- a yarn is kept for 24 hours in a constant temperature/humidity chamber which is maintained under standard conditions, that is, a temperature of 25° C. and 65% relative humidity, and the test samples is then measured according to ASTM 2256 method using a tensile tester.
- a coefficient of kinetic friction (F/F ⁇ s) between fibers is measured while rubbing yarns at a rate of 3 cm/min using a friction tester (Model name: YF-850 commercially available from TORAY). Also, a coefficient of kinetic friction (F/M ⁇ s) between fibers and a metal is measured while rubbing a Ni-coated metal with a yarn at a rate of 200 m/min. Then, a ratio of an F/F friction coefficient is calculated by dividing an F/F ⁇ s value by an F/M ⁇ s value.
- Instron 4465 (commercially available from Instron, US) is kept for 24 hours under standard conditions (20° C. and 65% relative humidity) according to the ASTM D 5034 standard method. Then, a tensile strength of a textile having a width of 10 cm and a length of 15 cm is measured.
- Instron 4465 (commercially available from Instron, US) is kept for 24 hours under standard conditions (20° C. and 65% relative humidity) according to the ASTM D 2261 standard method. Then, a tear strength of a textile is measured.
