Description
Technical field:
The present invention relates to a kind of fabric for safety air bag, this fabric has good folding property, and the air bag of making can keep the key property of air bag upon deployment, has the low slip characteristic of the part of making simultaneously.
Background technology:
In recent years, along with the exploitation and the construction of rapid development of automobile industry and highway, the travel speed of automobile is more and more faster, and the generation of traffic accident is also more frequent, so that the security of automobile just becomes is particularly important.Air bag as one of automotive safety spare part improves the installation rate rapidly along with the raising of people's awareness of safety.The groundwork process of air bag: after bumping, between occupant and Che inner part, open a gassiness sack rapidly; allow the occupant pounce on air bag; absorb passenger's kinetic energy by the discharging throttling damping of air bag; make to collide in the fierce car and cushioned, to reach protection passenger's purpose.
Four-stage has been experienced in the development of air bag: first generation product is to make type coated fabric air bag, and its fabric face is coated with chlorobutylene, to reach the choke effect.Second generation product still for making type coated fabric air bag, just changes silicone coating into.Third generation product is to make type non-coated fabric air bag, and the structure of fabric self has gas barrier property.The 4th generation product be the full moulding of non-coating, this air bag is processed into packed on loom, belongs to the non-type of making.
At present, a lot of researchs have been carried out from the heat resistance of air bag, low air permeability aspect.Be coated with the base cloth of rubber because the increase of its weight, just softness reduction, be difficult for the increase of folding and manufacturing cost, can not satisfy the growth requirement in market.Therefore, not having the coating air bag becomes main development trend with base cloth, and little, the firm softness of slippage on sewed part and low air penetrability put forward various plans when launching for it.
In Chinese publication CN1603174A, propose a kind of lightweight, had the foundation fabric for gas bag of low air permeability, contain the odd-shaped cross section silk in the synthetic fiber filament of formation foundation fabric for gas bag, the monofilament cross section flatness of odd-shaped cross section silk is 1.5-5.0, and the boiling water shrinkage of shrinking the preceding synthetic fiber of processing is 6-15%; Among the publication CN 1381366A, use thermoplastic fiber materials, making a kind of air penetrability under 50kPa pressure reduction is 2.5L/cm
2/ min, this high-density textile for air bag is a kind of air bag fabric of the low air penetrability that the air penetrability characteristic is high when keeping necessary mechanical property and having high pressure; Among the publication CN1259177A, be the 550-650 dtex with the line density scope, the monofilament radical is the airbag of the polyamide filaments manufacturing of 100-125 root in the yarn, and the scope of this fabric rate of loading dynamic venting quality (SWDP) value is 0.1-0.3 (lmm/dm
2MinkPa), more preferably 0.2-0.25 (lmm/dm
2MinkPa); The industrial fabric that is used for airbag that publication CN1242807A tells about, by thick filament number from 5 to 14dtex and thin filament number form from 1.5 to 5dtex mixed yarn, total fiber number 30 and 1000dtex between.The crin of yarn and filament are evenly to mix with 1: 1 to 1: 5 ratio, make to such an extent that fabric has high ultimate strength and tearing brute force in low weight, good folding property and low-permeable; The uncoated fabric of putting down in writing among the patent WO96/05985 adopts hot-air contraction＜6% and minimum of contraction power＞0.2 * 10
-2The polyamide filaments of N/tex is as raw material, and its air permeability is less than 3 liters/decimeter
2/ minute, residue boiling water shrink＜2% and through the tearing brute force of weft yarn greater than 110N; Publication CN1637178 puts down in writing a kind of polyamide fiber polyamide fiber for uncoated airbags, it is characterized in that, this high strength polyamide fiber for uncoated airbags is made up of smaller or equal to the polyamide monofilament of 4 Denier fineness, the load-deformation curve of this polyamide monofilament of Ce Dinging is at normal temperatures: when placing the pre-stress of 1.0g/d, and stretching less than 5%; The mid-term that places 4.5g/d is during stress, stretching less than 12%; Till broken, stretch more than 3% or 3% from the tensile break strength that applies minimum 9.0g/d.But do not solve the anti-slipping property that gas cell fabric is made the place in the above-mentioned patent.
United States Patent (USP) 09/326368 has proposed to improve the slippage resistance of making position and base cloth with the solder joint mode, but because the fabric bead is not exclusively firm, has damaged the closed structure that the polymer bead produces.Patent WO2001/023219 uses a kind of method of new welding, reinforce with sewn seams, can improve antiskid and move resistance, but because the film that this method is usually directed to make the fabric downside contacts with fabric that second tunic was handled and is under the high-frequency energy, thereby the attachment point place between two-layer fabrics forms the polymer bead, increase later process, cause cost to improve.
Summary of the invention:
When the object of the present invention is to provide a kind of maintenance air bag key property and having airbag deployment, the fabric for safety air bag that slippage on sewed part is little.
There is the long filament of two or more different initial moduluss in fabric for safety air bag of the present invention in warp-wise and/or the broadwise, and the initial modulus variance rate of high initial modulus long filament and low initial modulus long filament is 10～70%, and variance rate meets following formula 1:
C (%)=(A-B) * 100/A (formula 1)
C: initial modulus variance rate
A: high (or maximum) introductory die value (cN/dtex)
B: low (or minimum) introductory die value (cN/dtex).
The fabric that the present invention relates to has been taken all factors into consideration the requirement of gas cell fabric characteristic, selects the long filament of two or more different initial moduluss for use, the long filament of the different initial moduluss of wherein preferred 2-3 kind, and the initial modulus variance rate is controlled at 10～70%.The long filament initial modulus claims also " elastic modelling quantity " that it is meant the ess-strain ratio of one section straight line portion of beginning on the long filament stress strain curve.The size of long filament elastic modelling quantity is represented the complexity of long filament under the certain load effect, and it has reflected the rigidity of long filament, and the long filament initial modulus is big, and its rigidity is strong, just is difficult for deformation in weaving process; Initial modulus is low, and a little less than the rigidity, deformation easily takes place in weaving process long filament.The long filament of different deformation (being the long filament of different initial moduluss) makes fabric form between long filament the not structure that checks and balance of easy glide, makes fabric show high anti-slipping property, promptly high slippage resistance.Simultaneously, the long filament of different initial moduluss makes the fabric of weaving generation have the just soft of appropriateness, the shape that the air bag that fabric is made can be certain, the performance that have softness again, easily folds.
Certainly, if the variance rate of long filament initial modulus is low excessively, promptly be lower than 10%; then in weaving process, can't guarantee checking and balance between different initial modulus long filaments; cause the anti-slipping property of fabric and reduce, the air bag that fabric is made exists gas leakage, effect weakens to personal protection hidden danger upon deployment.Simultaneously owing to pin down reduction between long filament, cause the firm softness of fabric may be too high or or low excessively, can't satisfy the performance requirement of gas cell fabric to firm softness.Long filament initial modulus difference surpasses 70%, and the long filament of different initial moduluss pind down strong, made that the firm softness of fabric is too high, and folding property is affected, and the absorbability of impact energy reduces during airbag deployment, reduces the protective effect of air bag to human body.So we require the initial modulus variance rate to be controlled at 10～70%, preferred 15～60%, such fabric can keep high slippage resistance, has simultaneously the firm softness of appropriateness again, the absorption of impact ability and sew up antiskid and move requirement when guaranteeing the expansion of air bag.
Fabric for safety air bag of the present invention for folding property and the anti-slipping property of guaranteeing fabric, for the long filament of selecting for use, requires high initial modulus long filament, and its introductory die value is: 21.1～51.0cN/dtex; Low initial modulus long filament, its introductory die value is: 4.4～21.1cN/dtex, wherein, the preferred high introductory die value of long filament is: 25.0～42.5cN/dtex; Preferred low introductory die value is: 6.0～15.5cN/dtex.When other conditions were identical, the elastic modelling quantity of long filament was big, then fabric stiffening (being the firm softness height of fabric); Otherwise elastic modelling quantity is little, then fabric sofetening (being that the firm softness of fabric is low).
Fabric for safety air bag of the present invention is because the long filament of different initial moduluss has been selected in combination for use, so the cling property of fabric is good, its indicator reaction fabric slippage resistance, according to standard A STMD6479-02 test, warp-wise slippage resistance is 400-1000N, and broadwise slippage resistance is 300-900N.The high pressure-temperature air-flow was to the impact and the stretching action of air bag when high slippage resistance can make air bag bear inflation.If warp, the broadwise slippage of fabric are had a low resistance in 300N, then fabric is made place's easy glide upon deployment, causes gas leakage.Slippage resistance as fabric is higher than 1000N, and then the cohesive force between fabric silk and the silk is very big, and fabric face is harder, and air bag is difficult for folding, and impact power absorbability weakens upon deployment, instead easily the protected personnel is produced injury.The concrete method of testing of slippage resistance will describe in detail in aftermentioned.
Fabric for safety air bag of the present invention makes up the long filament of different initial moduluss, because initial modulus is relevant with the long filament rigidity, i.e. the long filament of different rigidity combination has overcome high stiffness fabric and the generation of super soft fabric.According to standard A STM D4032 test, the firm softness of this fabric, warp-wise: 4.0～35.0N, broadwise: 4.0～30.0N.Wherein, preferred warp-wise: 5.0～30.0N, broadwise: 5.0～25.0N.
Fabric for safety air bag of the present invention, the fabric of selecting for use the long filament of different initial moduluss to be woven into except that the firm softness with high anti-slipping property, appropriateness, has kept the requirement of gas cell fabric basic property simultaneously.According to standard JIS L-1096 test, the warp direction stretching fracture strength of fabric is: 400-1000N/cm, the broadwise tensile break strength is: 400-1000N/cm.Tensile break strength is lower than 400N/cm, and the high-voltage high-speed high temperature gas flow can't be guaranteed impact and stretching action that air bag produces when holding impact that the occupant produces air bag, inflation when being impacted; Intensity is too high, then aspects such as precursor, fabric tissue, thickness, manufacturing has all been proposed requirements at the higher level, and this certainly will cause the rising of cost, can not satisfy the requirement of gas cell fabric development trend.For gas cell fabric, the preferred 500-800N/cm of tensile break strength of fabric warp, broadwise.This can the guaranteed performance requirement, can guarantee the market competitiveness again.
Fabric for safety air bag of the present invention, the long filament of different initial moduluss contains 60-144 root monofilament in the long filament, and the fiber number of long filament is: 300-700dtex.The fiber number of long filament is too high, and the fabric thickness that then is made into is excessive, and firm softness height, is difficult for folding and the protection personnel being existed the potential possibility of injury; If fiber number is low excessively, the mechanical performance of the fabric that then is made into can not be guaranteed, and production efficiency is low, increases manufacturing cost.The present invention considers that from aspects such as the firm softness of fabric, slippage resistance, tearing strengths about 350-500dtex, filament number be the best with total fiber number about 2-8dtex.Monofilament radical in the long filament has certain influence to the permeability of fabric.Under the prerequisite of equal densities, fiber number, if the monofilament radical the more, then the contact-making surface of monofilament merchandiser silk increases, and the space between long filament diminishes, and fabric air-permeability shape is reduced.Certainly, the monofilament radical the more, making efficient and cost also can correspondingly increase.Take all factors into consideration, the monofilament radical is preferred at 72-136.
Because air bag and protected personnel's life security are closely related; so to the requirement that the material of selecting for use also is necessary, requiring this material must be the material with favorable mechanical performance (high-strength, light specific gravity, good frictional behaviour and ABRASION RESISTANCE, good springiness, initial modulus is low, elongation is big), gas permeability (airtight or little ventilative), thermal property (high-melting-point, heat-resisting, ageing-resistant) and highly shrinkable (air-tightness) and chemical stability (ageing-resistant).Polyamide fiber has characteristics such as initial modulus is low, good springiness, heat content height.Its fabric has stress distribution under the dynamic load effect even.Advantages such as absorbability reaches greatly that shock resistance is good, heat resistance and anti-flammability are better, in addition, the firm softness of polyamide fabric is good, long-term foldingly to be difficult for becoming fragile.Particularly polyamide 66 has good heat resistance, intensity height, has suitable ductility, and just softness can be good, thereby obtains immense success in this market of gas cell fabric.Fabric preferred polyamide 66 long filaments of the present invention.
Fabric for safety air bag of the present invention, its main production is: long filament is woven into the fabric grey cloth again through warping, and this grey cloth can be checked after super-dry and make textile article; This grey cloth also can be made textile article again through post processing processing.Post processing can be a coating, also can be that textile article is made in concise processing again.
Fabric for safety air bag of the present invention because the preferred long filament of different initial moduluss makes fabric have high anti-slipping property, has good firm softness simultaneously, and the air bag of making has the good folding property and the slipping property of anti-suture site.
