Description
Technical field
The present invention relates to a kind of lightweight, have the also excellent airbag (airbag) of low aeration and economy and use base fabric.
Background technology
In recent years; as one of automotive safety spare part; on most of automobile airbag is housed all; when automobile generation collision accident, after the sensor senses impact, produce high temperature and high pressure gas from force lift; and launch airbag hastily by this gas; when thereby the health of driver or co-driver flies out to the direction of colliding, can prevent that head from bumping against control wheel, Windshield, automobile door glass etc., therefore can utilize this airbag to protect.
What used on airbag is to be coated with elastomeric application base fabrics such as chloroprene, chlorosulfonylation alkene, polysiloxane in the past, and its reason is resistance to effect of heat, the air property cut off (low venting quality) and the flame resistance height of these materials.
Yet in these coating materials, its weight of base fabric that is coated with chloroprene or chlorosulfonylation alkene increases to some extent, and flexibility can not meet the demands, and cost is also higher, therefore if use as foundation fabric for gas bag, will have a lot of problems.In addition, though the polysiloxane application base fabric that still uses in part has improved above-mentioned shortcoming to a great extent so far, still can not meet the demands.
Therefore, adopted the airbag that is not coated with that is not coated with foundation fabric for gas bag of not implementing application just becoming main flow recently, and proposed following scheme for lightweight, the good property deposited and low venting quality.
For example, (1) is put down in writing as speciallyying permit No. 2538934 communique, the raw yarn above with 8.5g/d, that 3dpf is following, the method for the base fabric of the acquisition property deposited excellence; (2) open flat 1-122752 communique as the spy and put down in writing, weave after the high-density fabric,, obtain the method for lightweight, low venting quality base fabric by implementing to shrink processing or calendering processing; (3) open flat 4-2835 communique as the spy and put down in writing,, obtain lightweight and under the 124Pa differential pressure, have 0.5cc/cm by carrying out two sides calendering processing
2The method of the base fabric of/second following low venting quality; (4) open flat 6-41844 communique as the spy and put down in writing, handle, make the strand swelling that constitutes cloth and obtain the method for low venting quality base fabric by implement chemical shrinkage to fabric; (5) open flat 8-325888 communique as the spy and put down in writing, mix monofilament fineness and be the thermoplastic synthetic fiber's of the thermoplastic synthetic fiber of 1.5d～7.0d and 0.2d～1.5d method.
But above-mentioned in the past not being coated with in the airbag all has problems.That is, in the past in the example (1), though the property deposited excellence remains further to be improved aspect aeration.In addition, owing to dwindled monofilament fineness, therefore cause the disconnection of the long filament when weaving easily, at base fabric qualitatively or weave and have problems in the running, the rotating speed of loom also is difficult to improve, and it is higher to weave cost.With regard to example (2) in the past, owing to roll processing, many one procedure have so not only improved cost in Fabrication procedure, also impair flexibility.In example (3) in the past, though can obtain lightweight and low venting quality, also because of implementing calendering processing, increased one procedure this moment in Fabrication procedure, so not only improved cost, also impairs flexibility.In the example (4), because of implementing chemical treatment, manufacturing cost increased in the past, and chemical reagent can cause that the decline of former yarn intensity is the decline of base fabric intensity, if use as airbag, had problems on its reliability.With regard to example (5) in the past,, increased one procedure, therefore the problem that exists manufacturing cost to rise because of 2 kinds of strands of the different monofilament finenesses that will make respectively combine.
Summary of the invention

The specific embodiment
Foundation fabric for gas bag of the present invention is weaved the long filament of syntheticfibres after shrink processing and make, comprise odd-shaped cross section silk in the long filament of the syntheticfibres after it is characterized in that processing, and the syntheticfibres before the processing has specific boiling water shrinkage with specific flatness.
Be used for the syntheticfibres of foundation fabric for gas bag of the present invention, be not particularly limited, especially can use fatty polyamide fibers such as nylon 66, nylon 6, nylon 46, nylon 12 as raw MAT'L; Aromatic polyamide fibres such as polyamide-based fiber; Poly-ester fibres such as mekralon or polyethylene terephthalate, polybutylene terephthalate.As other raw MAT'L, also can use Wholly aromatic polyester fiber, superhigh molecular weight polyethylene fibers, PPS fiber, polyether ketone fiber etc.Wherein, from economic considerations, special preferred polyester fiber or polyamide fibre.In addition, part or all of these fibers obtained also can by reclaimed materials.In addition, in order to improve the processability in raw yarn Fabrication procedure or back manufacturing procedure, also can contain various additives in these syntheticfibress.For example can contain antioxidant, heat stabilizer, flatting agent, antistatic agent, thickening agent, fire retardant etc.Also have, these syntheticfibress also can be colored silk.
The maximum feature of foundation fabric for gas bag of the present invention is to constitute to contain in the long filament of syntheticfibres of foundation fabric for gas bag to be not common circular section silk but to have the odd-shaped cross section silk of specific flatness.Have the odd-shaped cross section silk (being designated hereinafter simply as flat filament) of specific flatness by employing, when being made into fabric, can make the major diameter in monofilament cross section mutually stacked, thereby reduce the space in the unit area on the fabric cross section.Therefore, be woven into the circular section silk that uses equal fineness and compare when knitting density on an equal basis, the throughput in the time of can suppressing airbag and launch.In addition, when being designed to equal throughput, total fineness can be reduced, thereby the thin and light flexible base fabric that has can be made.
The flatness in the monofilament cross section among the present invention is that the major diameter when being approximate ellipsoidal with the monofilament cross sectional shape is represented with the ratio of minor axis.This cross section is not required it must is strict ellipse, and in the scope that does not influence the flat property of single-piece, part exists projection or recess also without any influence, does not also need left-right symmetric.In this case, myopia is the ellipse of harmless its monnolithic case, and the longest length is made as major diameter, and the shortest length is made as minor axis, obtains flatness at last and gets final product.
Put down in writing the typical example of odd-shaped cross section among the present invention among Fig. 1.Certainly, this is a typical example, is not limited in this.The a of Fig. 1 is a major diameter, and b is a minor axis, and flatness is calculated by a/b.
In order to obtain effect of the present invention, described flatness is advisable in 1.5～5.0 scopes, is preferably 1.5～4.0.Preferred especially oval as the cross section.If flatness is less than 1.5, then flat effect can die down, and if greater than 5.0, the fracture of wire in the time of then can becoming throwing, the reason of fluffing, not ideal.In addition, there is no need all monofilament and all have the interior flatness of above-mentioned scope, as long as a part wherein is 1.5～5.0.But if will strengthen flat effect, the monofilament number that then has a flatness of above-mentioned scope accounts for being advisable more than 50% of total monofilament number of long filament, more preferably more than 70%.
Being used for flat filament of the present invention can adopt known in the past the whole bag of tricks to obtain.For example can obtain flat filament, perhaps also can adopt composite spinning method to spray simultaneously after the poly-mer more than 2 kinds, remove a kind of composition at least and obtain flat filament by the direct throwing method of the hole ejection poly-mer that reels off raw silk from cocoons from abnormity.Consider common preferably the former direct throwing method from the easy degree of throwing, the simple degree of operation.
When making the thin especially long filament of monofilament fineness, use the latter's composite spinning method to be advisable.At this moment, removing a kind of composition at least can carry out after stretching or after making cloth and silk.
Therefore, foundation fabric for gas bag of the present invention not only comprises from the raw yarn stage and begins just to carry out woven base fabric with flat filament, is also included within that the raw yarn stage weaves with common circular section silk and removes a part of composition and make the base fabric of flat filament after making cloth and silk.
Another feature of foundation fabric for gas bag of the present invention is that the boiling water shrinkage of syntheticfibres before shrinking processing that is used for foundation fabric for gas bag is 6～15%.If boiling water shrinkage is less than 6%, even then use flat filament, after shrinking processing, can not get low venting quality, and if surpass 15%, the thickness that shrinks the fabric after processing can increase, and impairs densification, and is not ideal.The preferred value of boiling water shrinkage is 7～13%.Cloth and silk of the present invention shrinks the furnace run temperature in the processing, is not particularly limited, usually 90～200 ℃ of enforcements.Consider from obtaining low aeration angle, preferably handling below 160 ℃.Can adopt heat setter, boiling water passage (pass) etc. to carry out during processing, be not particularly limited, also can use rising of fabric warp thread direction to feed the processing machine that (over feed) can reach 2～15% scopes.
In addition, the total fineness of filament of synthetic fibre that constitutes foundation fabric for gas bag of the present invention is at 100dtex～700dtex, and monofilament fineness is advisable at 0.1dtex～7.0dtex.Preferred total fineness is 120dtex～500dtex, and monofilament fineness is 0.1dtex～5.0dtex.That is, when total fineness less than 100 dtex, pulling strengrth and peel strength are abundant inadequately, if and surpass 700dtex, though then do not have problems on the intensity, impair the flexible and property deposited of fabric, and the hardening of cloth and silk surface might injure the skin of human body when therefore colliding, not too favourable.If the not enough 0.1dtex of monofilament fineness is difficult to carry out spinning, and the effect of flat filament of the present invention dies down, and is therefore not ideal.On the contrary,, impair the flexibility of fabric if surpass 7dtex, not too favourable, therefore undesirable during from the property deposited or to the influencing angle and consider of human body.
In addition, the venting quality of foundation fabric for gas bag of the present invention under 20kPa pressure is at 0.71/cm
2Be advisable below/the min, more preferably at 0.51/cm
2Below/the min.The base fabric venting quality here is to adopt high pressure venting quality experimental engine (OEM system (strain) system), and the throughput when being set at 20kPa pressure is obtained.If above-mentioned throughput surpasses 0.71/cm
2/ min, the moment during then as airbag launches performance and can descend, and is therefore not ideal.
