ラストマーの種別を変更すること等が行われている。2. Description of the Related Art As a safety device for protecting an occupant of an automobile, an air bag has been increasingly mounted. Among the airbags, particularly, the airbag for the driver's seat is usually mounted as a module including an inflator case in a narrow place such as a steering wheel or an instrument panel, so that the storage volume of the airbag is desirably small. Conventionally, in order to make the storage volume of the airbag compact, the use of fine fibers in the fabric of the base fabric and the type of elastomer coated on the base fabric to maintain the confidentiality of the bag have been changed. And so on.

ことが必要である。[0004] Recently, in order to make instruments such as speed panels easier to see by further increasing the void space of the steering wheel, and to increase the space inside the vehicle, the folding storage volume is made as small as possible to reduce the compactness and softness of the texture. There is a strong need for a textile base fabric to obtain an improved airbag. In order to meet the demand for compactness and softness of the texture, it is necessary to further reduce the fineness of the multifilament yarn used for the woven fabric and the fineness of the single yarn constituting the same.

脂の均一なコーティングを損なう原因となる。[0005] The airbag fabric is highly powerful and has low air permeability in order to satisfy the function of instantly inflating the airbag in the event of an automobile collision and protecting the occupant's face and frontal head in the event of a collision. Therefore, it is necessary to use a high-density woven fabric using high-strength yarns as compared with a normal clothing base fabric. The higher the weaving density of a woven fabric, the more the ear ends become wavy.
Occurs. That is, in bag making of an airbag, a bag body is made by sewing a cut piece of the base cloth, but in order to make the most effective use of the base cloth for the airbag, the base cloth is usually brought to the vicinity of the ears. A design of cutting as a bag-making pattern piece is adopted. When ear ears are generated near the ear end of the base cloth,
In particular, the laser cutter cutting does not cut into the shape as designed, which makes subsequent sewing difficult, and also fails to achieve the designed airbag shape, which impairs the bag making of a normal functioning airbag. Further, the ear tarmi of the greige machine causes winding on a take-up roll on a loom, subsequent scouring, generation of creases in ears in setting, and damage to uniform resin coating.

Has been described. In these methods, the ground yarn is 470 to 350 dte.
It is concerned with the formation of ears of a woven fabric composed of x threads.

問題がある。[0007] In order to respond to the compactness and softness of the airbag, when weaving a woven fabric using a fine yarn of 250 dtex or less as ground yarn, the fineness near the ear portion is also reduced along with the fineness. If the weaving tension of the additional yarn or the entangled yarn is increased to increase the tightening of the weft, the single yarn breaks during weaving and stops, resulting in a decrease in weaving performance. There is a problem that occurs.

に織られた織物が代表的なものとして挙げられる。[0014] Since the woven fabric is constituted by using the polyamide multifilament yarn having a relatively small fineness as described above, the thickness of the base fabric is small and the base fabric is flexible. An airbag that is small and can be folded and has excellent storage properties can be manufactured. Although the structure of the woven fabric is not particularly limited, for example, a woven fabric woven in a plain weave, a weft weave, or a lattice weave is a typical example.

The mechanical properties of the fabric must be of a level that can satisfy the pressure-resistant mechanical properties required during the inflation operation of the airbag. In the present invention, the multifilament yarn having a relatively small fineness is composed of a high-strength polyamide fiber, and the cover factor (K) is 2000 to 2500.
By woven into a woven fabric having a high woven density specified in the above, a woven fabric satisfying predetermined pressure-resistant mechanical properties is obtained.

More preferably, the tensile strength is 6.2 cN / dtex.
As described above, the polyamide fiber having a breaking elongation of 15 to 30% does not impair the weavability as a high-density woven fabric satisfying a predetermined cover factor. The upper limit of the tensile strength at which a polyamide multifilament yarn having the above-mentioned fineness can be produced without breaking in the yarn length direction is approximately 9.7 cN / dtex.

Here, the cover factor (K) is the square root of the total fineness of the yarns constituting the woven fabric and 1 inch (2.54 cm).
It means the sum of the product of the number of threads per unit (woven density) and the weft. That is, it is calculated by the following equation (1).

54 cm). In addition, the total fineness of the warp (or weft) refers to the total fineness of the yarns constituting the woven structure unit in the warp direction (or the weft direction) of the woven fabric, and when the minimum unit of the woven structure is a single yarn, When the fineness of a single yarn is composed of a plurality of twisted yarns, composite yarns, and aligned yarns, it refers to the sum of the finenesses of the constituent yarns.

く、製織における停台の原因となる。The fineness of a single yarn constituting the total fineness of the yarn is 0.5
It is preferably set to 4.5 dtex. When the single-fiber fineness is in this range, the base fabric is flexible and excellent in storability, and the multifilament yarn does not fluff, and the weaving operation rate does not decrease due to a stop during high-density weaving. In the present invention, the ground portion of the woven fabric has a total fineness of 50 to
It is woven into a high-density woven fabric having a cover factor of 2000 to 2500 using a multifilament yarn of 250 dtex. However, when weaving with a high weaving density using multifilament yarns with such a small fineness, if the ears are simply made of yarn of the same fineness as the ground or less, the gap between the ground and the ears of the woven fabric can be reduced. Due to the difference in warp tension generated in the above, fluff is likely to be generated on the warp, and in particular, ear hanging and fluff near the ears are likely to occur, which causes a stop in weaving.

れがある。The higher the density of a woven fabric, the higher the tension of the weft during weaving at the center of the woven fabric and the lower it is near the edge of the weave. Concentrated in the vicinity of the end, the woven tissue in the vicinity of the end of the ear collapses and ear ears occur. In order to prevent tissue collapse near the ear, it is necessary to tighten the weft at the end of the ear, but if the tension at the end of the ear is increased to increase the tightening, single yarn breakage may occur. Stopping may occur.

拘束力が十分であるため、耳タルミの発生がない。In the present invention, weaving is carried out by inserting two or more monofilament yarns at the ear end and inserting a twine at the most ear end to cut the single ear yarn and the ear. Fixed the problem of stopping. The additional yarn (also referred to as a force yarn) is supplied to the loom as a warp separately from the ground portion of the main body. Monofilament yarn is preferable for increasing the weft at the end of the ear, in order to prevent breakage of the weft yarn by using the rigidity of the warp to prevent breakage of the yarn under high tension, and to further increase the weft yarn binding. It is preferable to use a finer yarn than the ground portion. The fineness of the monofilament yarn is preferably 10 to 100 d.
tex, more preferably 22 to 55 dtex.
When the fineness of the monofilament yarn is within this range, the yarn has sufficient strength and can withstand tension, and has an appropriate rigidity and a sufficient weft restraining force, so that ear ears do not occur.

When the cover factor of the ground portion is 2,000 or more, the number is two or more, preferably two to four. Further, it is desirable that the interval between the monofilament yarns is made as small as possible so that the monofilaments come into contact with each other. When the cover factor is around 2500, 4 to 10 are preferable.

When the total fineness and the number of fine fineness yarns are in the above range,
The tension dispersion from the monofilament yarn is performed properly,
The tension applied to the yarn is moderate, there is no breakage of the yarn, there is no stop in weaving, and there is no deterioration in the quality of the woven fabric due to the unevenness of the resin coat at the yarn joint.
