の顔面、前頭部を保護しようとするものである。2. Description of the Related Art In recent years, the practical use of airbags for ensuring the safety of occupants in automobiles has been rapidly increasing. In the event of an automobile collision, the airbag activates a sensor in response to a collision and generates high-temperature, high-pressure gas, which causes the airbag to inflate instantaneously. To protect the department.

作られていた。Conventionally, a plain woven fabric using 100 to 1000 denier nylon 6 or nylon 6.6 filament yarn has been used as an airbag, and chloroprene rubber or the like has been used for the purpose of improving heat resistance, flame retardancy, air barrier properties and the like. The base cloth coated with the elastomer resin was cut and sewn into a bag.

ても、折りたたみ難いという問題があった。[0004] However, the base fabric for an airbag obtained by applying and laminating these elastomer resins to a base fabric is usually such that the elastomer resin is applied on the surface of the base fabric at 40 to 100 g / m 2 , which is quite heavy. In addition, when the airbag is inflated, the face may come in contact with the abrasion when it is inflated, which is not preferable, and there is a problem that it is difficult to fold in terms of storage.

つある。[0005] In addition, such a base cloth also has
Since the coating process is performed, the processing itself is complicated, and the cost is increased. For this reason, recently, a so-called non-coated base fabric for an airbag, in which such an elastomer resin is not applied to the base fabric and is not applied, is emerging.

問題点を有するった。However, airbag fabrics are required to have high strength and low air permeability due to the feature that the airbag is instantaneously inflated in the event of an automobile collision and the occupant's face and frontal head are protected in the event of a collision. Is done. For this reason, a high-density woven fabric using high-strength yarn is required for a woven fabric for an airbag, compared to a normal woven fabric. In particular, in the case of a non-coated base fabric for an airbag, an elastomer resin is applied to the base fabric,
In order to obtain low air permeability with a single woven fabric without stacking, a higher density woven fabric is required. This high-density woven fabric has an essential problem that ear pallets occur in a wavy state near the ears.

In the case of a non-coated base cloth, the edge of the cut product is easily frayed by such cutting with a knife or punching with a dumbbell, and therefore, the cut product is usually cut one by one using a laser cutter.

In addition, it is difficult to obtain an accurate shape as an airbag, and it becomes difficult to provide an airbag having a normal function.
In addition, ear pricking on the greige machine not only impairs the processability in the roll winding and subsequent scouring and setting processes, but also causes wrinkles, and it is extremely difficult to uniformly apply. In this case, workability and workability are significantly reduced.

However, it has been found that by changing the warp denier of the ear portion, such a problem is unexpectedly solved at once.

For example, heat stability, antioxidants, light stabilizers, leveling agents,

The fineness and total fineness of the single fibers constituting the woven fabric are not particularly limited as long as they satisfy the mechanical properties required for an airbag, but the fineness of a single yarn is preferably 1 to 7 denier, and furthermore, the total fineness Is preferably 100 to 500 denier. Depending on the strength of the single fiber, if it is less than 100 denier, the strength required as an airbag is insufficient, and if it exceeds 500 denier, the ground becomes thick and bulky, It becomes inferior to the compact storage property which is a necessary characteristic.

A thin plain weave is particularly preferred. The weaving density varies depending on the fineness of the base cloth for coating and the base cloth for non-coating, and the fineness of the woven yarn, but those having a cover factor of 1700 to 2500 are preferable. Further, in the case of the base fabric for coating, the cover factor is preferably 1700 to 2,000, and in the case of the non-coating base fabric, the cover factor is more preferably 1700 to 2500. The cover factor of such a woven fabric refers to the sum of the product and the weft of the square root of the yarn fineness and the number of yarns per inch. That is, it is calculated by the following equation.
【００１６】 Ｋ＝（Ｄ１）1/2 ×Ｎ１＋（Ｄ２）1/2 ×Ｎ２ 式中、Ｋ：カバーファクター、Ｄ１：経糸総繊度、Ｎ

しく、８０％から５０％細いことがさらに好ましい。The occurrence of ear pallets in the airbag fabric is as follows.
The weft tension during weaving is high in the center of the woven fabric and low in the vicinity of the ears. However, this is considered to be a phenomenon in which the woven structure near the ears is broken, and this is a problem that occurs peculiar to the high-density fabric regardless of the loom model. As a result of intensive studies on the improvement of the ear cling, it is considered that the binding force of the weft to the ear can be increased during weaving by making the ear thinner than the warp denier. The wider the width of the narrow warp denier ears, the greater the effect of improving ear clasps.However, the thin ears of the warp denier are not used as an airbag base fabric. Become. On the other hand, when the width of the narrow ear portion of the warp denier is small, the loss is reduced, but the effect of improving the ear lash is reduced. For this reason, the width of the narrow ear portion of the warp denier is preferably in the range of 0.1 to 3% of the ground main body portion. Further, the warp denier of the ear portion is preferably 80% to 20% thinner than the warp denier of the ground main body portion, and more preferably 80% to 50% thinner.

The cutting of the coat base cloth is usually performed by laminating a plurality of coat base cloths and punching with a knife. In the case of a non-coated base cloth, the edge of the cut product is easily frayed by punching and cutting with the knife,
Usually, it is cut one by one by a laser cutter,
Since there is no ear cling in the vicinity of the ear, it can be cut into a shape as designed and sewing is easy.
