性を向上させる改良が行われてきた。2. Description of the Related Art The mounting of airbags as an occupant protection and safety device for automobiles is increasing. An airbag is usually mounted as a module including an inflator case in a narrow place such as a steering wheel or an instrument panel. Under such circumstances, it is desired that the storage volume of the airbag be small. Conventionally, in order to make the storage volume compact, it is necessary to use a woven fabric of fineness yarn or cover the base fabric. Improvements have been made to improve the compactness and lightness of the airbag by selecting and changing the elastomer.

のソフト化に応え得る基布が強く求められている。[0003] For example, the fiber used for the woven fabric is 940 dt.
from ex to the base fabric of 470 dtex, and coated elastomers changed from 90~120g / m 2 coating of chloroprene rubber to 40 to 60 g / m 2 coating of silicone resin, in the current type of group to silicone co proboscis the fabric of 470 dtex Cloths are increasingly being used for non-coated airbags without the coating. Recently, airbags have been made more compact, and airbags have been made more compact, in order to make instruments such as speed panels easier to see by increasing the space of the steering wheel, and to minimize the storage volume of airbags in order to increase the space inside the vehicle. There is a strong need for a base fabric that can respond.

織物の耳端部の近傍が波打ち状態になるいわゆる耳弛み
（以下、耳タルミという）が発生する。[0004] In order to respond to the downsizing of the airbag and the softness of the hand, it is necessary to further reduce the total fineness and the single-filament fineness of the yarn used in the woven fabric. Airbag fabrics are required to have the function of instantaneously inflating the airbag in the event of a car collision and protecting the occupant's face and forehead in the event of a collision. Sex is required. Therefore, there is a need for a high-density woven fabric that uses relatively high-strength yarns as compared to ordinary clothing base fabrics. However, the more woven the fabric is woven at a high weaving density,
A so-called ear slack (hereinafter referred to as ear bulge) occurs in which the vicinity of the ear end of the woven fabric is wavy.

ことも重大である。[0005] In the manufacture of an airbag, a bag body is made by cutting the base fabric and then sewing it. In order to make the best use of the base fabric, the cutting pattern is designed to reach the vicinity of the ears of the base fabric. It is required to be used. Thus,
If ear lumps are generated near the edge of the ear, especially when cutting with a laser cutter, it will not be cut according to the design shape, which will not only make subsequent sewing difficult, but also accurately obtain the shape required by design. Therefore, an airbag having a predetermined normal function cannot be obtained. It is also important that ear pallets in a greige machine of a high-density woven fabric cause a roll wrinkling of the woven fabric, further scouring, fold creases in the set in a set, and a resin coating defect in non-breathable processing.

Japanese Patent No. 22637 discloses a method of inserting three or more entangled yarns between the outermost warp yarn and the entangled yarn.
Japanese Patent Application Laid-Open No. 9-302550 discloses a method in which the weaving density of the ears is greater than the ground body weaving density.
No. 53 discloses a method in which the woolen warp multifilament fineness of the woven fabric is smaller than the warp multifilament fineness of the ground part. These known methods are devised for the case where the ground yarn is 470 to 350 dtex, but in order to respond to the recent demand for compactness and softness of the airbag, if the ground yarn is thinned to 250 dtex or less, the ears of the woven fabric are reduced. If the weaving tension of the additional yarn or the entangled yarn is increased in order to reduce the fineness in the vicinity of the part and increase the tightening of the weft in the ear part, the loom stops due to yarn breakage during weaving. In order to avoid this stop, a method has been adopted in which the single yarn fineness of the ground yarn used is increased to increase the high tension, thereby reducing apparent ear pallets. The greige fabric of the airbag fabric woven in this way has no ears in appearance, but in order to prevent the occurrence of coating unevenness due to loosening of the base fabric during resin coating, the greige fabric is scoured or set or set on the greige fabric At present, it is necessary to reduce the slack of the base fabric by performing processing. However, in recent years, it has been required to reduce the processing cost by reducing the labor of the set processing and performing the resin coating processing directly on the greige machine.

れていることで、所定の機械的特性が付与されている。The airbag fabric of the present invention has a fineness of 2%.
If the woven fabric is formed of a multifilament yarn having a relatively small fineness of 50 dtex or less, the airbag can be manufactured to have a small thickness and softness, and can be folded lightly and compactly. In order for a woven fabric formed of multifilament yarns having a relatively small fineness of 250 dtex or less to function as a base fabric for an airbag, the mechanical properties of the woven fabric satisfy the pressure-resistant mechanical properties required when operating the airbag. It must be at the level of gain. In the present invention, the base fabric is a multifilament yarn of a high-strength polyamide fiber used as the multifilament yarn, and the cover factor (K) described later is woven to a high weave density specified by 2000 to 2500. Thus, predetermined mechanical properties are provided.

ある。The multifilament yarn used in the present invention has a tensile strength of at least 5.7 cN / dtex, preferably a tensile strength of at least 6.2 cN / dtex, and an elongation of 15 to 30%.
This is a multifilament yarn made of a polyamide fiber having the following, and which does not impair the weavability of a high-density woven fabric satisfying the above-mentioned predetermined cover factor. The maximum strength at which the physical properties of the polyamide fiber in the yarn length direction of the fiber are kept uniform is approximately 9.7 cN / dtex within a range in which yarn breakage is allowed during fiber production. Meanwhile, the cover factor of the fabric of the present invention must be 2000 or more. In the case of a woven fabric having a size of less than 2,000, the mechanical properties required during the operation of the bag cannot be satisfied because the tensile mechanical properties are small.

支障がでてくるおそれがある。In the present invention, the cover factor is
The sum of the product of the square root of the total fineness of the yarn constituting the woven fabric and the number of yarns per one inch (woven density) and the weft. That is, the cover factor is calculated by the following equation (1). K = (D1) 1/2 × N1 + (D2) 1/2 × N2. . . . (1) wherein, K: cover factor, D 1: the warp total fineness (dt
ex), N 2 : warp weave density (book / 2.54 cm),
D 2 : Weft total fineness (dtex), N 2 : Weft weave density (book / 2.54 cm). In addition, the total yarn fineness refers to the fineness of the yarn constituting the unit of the weaving structure in the warp direction (or the weft direction) of the woven fabric, and when it is one yarn, it refers to the fineness of the yarn. In the case of a twisted yarn, a plying yarn, and a drawn yarn, the total fineness of the yarns constituting the twisted yarn and the plying yarn is referred to. In the present invention, the total fineness is 500 dtex or less, preferably 67 to 250 dtex. When the total fineness exceeds 500 dtex, the lightness and compactness of the airbag deteriorate. On the other hand, when the total fineness is reduced, lightness and compactness are improved. When it is less than 67 dtex, there is a possibility that weaving of a woven fabric having necessary tensile and tearing mechanical properties may be hindered.

生して停台が起こり易くなる。The single filament fineness of the multifilament is 0.5 to
4.5 dtex is preferred. If it exceeds 4.5 dtex, the base fabric becomes hard and the storability becomes inferior. If the single yarn fineness is less than 0.5 dtex, fluff is likely to occur on the yarn in both the production of the yarn and the weaving of the high-density woven fabric. Therefore, it is unsuitable in terms of the performance of the base fabric and the processability of the yarn. The fabric base fabric for an airbag of the present invention, which is made of a multifilament high-density fabric having a relatively small fineness, does not prevent the occurrence of ear lumps due to weaving. The occurrence is likely to cause the loom to stop, which reduces the efficiency of production. This problem occurs more remarkably as the weaving density of the fabric increases. The weft tension during weaving is large at the center of the woven fabric and low near the edge of the ear. The nearby woven tissue collapses and ear pallets occur. It is desirable to increase the tightening of the weft at the ear end of the ear tail near the ear end. However, if this is done, the weaving tension at the ear end is increased, so that a single yarn break occurs and a stop is likely to occur.

製織される。The base fabric of the present invention can be woven by inserting a high-tension durable yarn or entangled yarn into a predetermined ear end independently of the warp specification of the ground portion to suppress a stop caused by fluff. Then, before winding the woven greige on the loom, the additional yarn insertion portion near the ear is melt-cut, and the warp and weft of the woven fabric are fixed with the molten fiber to relax the tension in the greige. Is wound up, and the end face of the wound woven fabric due to the additional yarn is prepared as a base woven fabric having no ear height or having a bent ear due to ear pallets or the like. That is, the woven fabric fabric for an airbag of the present invention has a high tensile strength different from the warp specification of the ground portion at a portion corresponding to the ear end of the filament warp group of the ground portion woven fabric for weaving the high weaving density described above. After inserting and weaving the additional yarn and / or twine yarn, prior to weaving and winding up the greige on the loom, the portion of the additional yarn and / or twine insertion near the ear portion is melted and removed to remove the woven fabric. It is prepared by melting and fixing the warp and the weft at the cut end face and then winding the woven fabric. Here, the predetermined ear end has a single thread breakage of 4 to 1 which does not occur even under a tension not less than twice the warp tension at the time of weaving applied to the ground portion of the monofilament or woven fabric of 10 to 100 dtex.
A total fineness of 50 to 250 dtex consisting of a single yarn of 0 dtex
Of multi-filament yarns of the same degree, and the total fineness of the entangled yarn with a large tightening force is 7
It is woven by inserting one or two multifilament yarns each composed of a false twisted yarn having a fineness of 0% or less or a single yarn having a modified cross section in units of two.

上でも好ましい。The base portion of the base fabric of the present invention is preferably woven with non-adhesive multifilament yarn in order to save labor in the scouring step. From the viewpoint of weaving properties, it is preferable to use a warp to which an entanglement, twisting, and warping oil agent is applied. Melt cutting method of the ear end, laser cutting, ultrasonic cutting, heat knife cutting, etc. can be used, but the cut surface is a single yarn is melted to form a resin,
Any method can be used to melt-bond the warp and weft on the end face of the cut molten base fabric and prevent collapse of the woven fabric structure at the cut end face with a simple external force at the contact level before processing such as heat setting or resin coating in post-processing. It may be a method. In the fusing method using a heat knife, the knife edge is sharp and the temperature of the knife is 4
It is desirable to have a mechanism in which the molten resin ball does not adhere to the molten portion at 00 to 700 ° C and is separated from the base fabric when the loom is stopped. In order to reduce the loss, it is preferable that the width of the piece removed by cutting is as small as possible at a position of 0.2 to 2.5 cm from the edge of the weaving base fabric between the temple during the weaving and winding-up.

リアミド繊維であることが好ましい。The base fabric woven as described above is a base fabric in which the ends of the ears are fixed by welding warps and wefts at the end faces thereof. An even coated base fabric is obtained. Alternatively, the base fabric in the greige state can be subjected to scouring / setting processing or greige setting processing and subjected to resin coating processing. The base fabric for an airbag of the present invention is made of a woven fabric of synthetic fibers such as polyester fibers and polyamide fibers. The synthetic fibers that make up the base fabric are
From the viewpoint of specific heat, polyamide fibers are preferred. Representative examples of polyamide fibers include polyhexamethylene adipamide fibers (nylon 66 fibers) and polycabramid fibers (nylon 6 fibers). The type of polyamide is not particularly limited, but since a high-temperature gas is ejected from the inflator into the airbag when the airbag is deployed, from the viewpoint of heat resistance, the polyamide fiber may be a polyamide fiber having a melting point of 215 ° C or higher. preferable.

If ηr is less than 2.5, it is difficult to stably obtain high strength, and polyamide having ηr 3.3 or more, particularly polyhexamethylene adipamide, is difficult to fibrillate due to poor spinnability due to gelation progress. The relative viscosity of sulfuric acid was measured by dissolving 1 g of fiber having no oil agent in 95.5% sulfuric acid (100 cc) and measuring it with an Ostwald viscometer in a thermostat at 25 ° C.
