有益なエアバッグに関するものである。BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an airbag which is one of safety devices for automobiles, and more particularly to an airbag which is particularly useful for protecting a passenger in a transport vehicle from a front or a side.

る。2. Description of the Related Art In recent years, as one of safety components for automobiles, the mounting rate of airbags has been rapidly increasing along with an increase in occupant safety awareness. In the event of a car crash, airbags
The impact is detected by a sensor, and a high-temperature and / or high-pressure gas is generated from the inflator, and the gas rapidly deploys the airbag to help protect the occupant.

出来る袋織り技術が注目されてきた。[0004] Conventionally, airbags for a driver's seat and a passenger's seat are conventionally used.
It is made by sewing two airbag base fabrics. However, a bag weaving technique capable of forming a bag at the weaving stage has recently attracted attention because of the improvement in performance of an airbag and a reduction in manufacturing cost.

が通常である。[0005] In addition, side protection airbags are often designed for rollover of automobiles,
Unlike airbags for passenger seats, it is said that it is necessary to secure internal pressure retention time of several seconds to 10 seconds after deployment. It is designed so that the occupant's head can be protected even during a rollover of the vehicle. Therefore, gas leakage from the woven fabric body must be prevented, and it is not practical for sewn products due to air leakage from the seams. At present, it is usual to coat the surface of a woven airbag base fabric.

バッグ部分と一体接合されている綴じ部分の厚みや経糸
のテンションが異なってくる。The base fabric for a woven airbag is a bag in which a plurality of fabrics are partially joined together to form a bag. The thickness of the stitched portion and the tension of the warp that are integrally joined are different.

くなる。In the case of a base cloth having different thicknesses and warp tensions in the width direction, wrinkles and changes occur in the base cloth during winding after weaving, and the quality of the base cloth deteriorates. In addition, after weaving, after weaving, inspection, scouring, drying, heat setting, and various post-processing steps, it becomes the final product, so if the quality of the base cloth deteriorates at the stage after weaving, The likelihood of worsening increases.

とが出来ない。Further, at the present stage, in the case of a side-impact woven airbag base fabric, it is often assumed that the vehicle rolls over. In order to improve the internal pressure holding performance of the bag, the woven airbag base fabric is used. A surface-coated airbag is used. If wrinkles are present in the base fabric, uniform coating becomes impossible, and the airbag cannot function as an airbag.

It is an object of the present invention to provide a woven airbag base fabric and a woven airbag which solve the above problem.

れたバッグの品位も高いものである。As is evident from Table 1, in the case of Example 1, the flatness of the base fabric was obtained because there was little unevenness in the thickness of the base fabric and there was almost no unevenness in the crimp rate of the warp.
The number of defects at the stage of greige is also reduced, and the post-processability is good. Further, since the crimp ratio of the warp is almost equal to that of the bag portion, there is no looseness of the warp and the weaving property is very good. In addition, the coatability is good and the quality of the obtained bag is high.

性は良好で、得られたバッグの品位も高いものである。In the case of Example 2, since the rate of change of the crimp ratio between the warps of the A and B portions is slightly larger than that of the Example 1, the weaving property is inferior. Since the thickness unevenness is small, the flatness of the base fabric is good, there are few defects such as winding wrinkles, and the post-workability is also good. In addition, since the base fabric has flatness, coatability is good, and the quality of the obtained bag is high.

Example of uneven thickness in the width direction of the base cloth
Although it is larger than 1, winding wrinkles in the weaving stage can be suppressed to some extent. In addition, the coating processability is
Compared with 1 and 2, there is a difference in thickness between the base fabrics, so it is somewhat inferior, but not so much as to deteriorate the coat processability.

いものとなる。In the case of Comparative Examples 1 and 2, as is clear from Table 1, since the thickness fluctuation rate in the width direction of the base fabric is large,
Wrinkling occurs at the stage of winding around the winding core after weaving, and the quality deteriorates. In the post-processing, the ears of the base fabric flap, the workability deteriorates, and the quality further deteriorates. In addition, the rate of change in the crimp ratio between the warps is large, and the warps are loosened, and the weaving property is significantly deteriorated. In addition, since the quality of the finished processing is poor, there is a high possibility that badness will occur during the coating process, and the quality of the bag will also be poor.

が出来る。The woven airbag base fabric and the woven airbag of the present invention have a small rate of change in the crimp rate between the warps in different portions of the weaving structure, so that the occurrence of warp loosening during weaving can be suppressed, and the weaving performance can be improved. Is improved and the thickness variation in the width direction of the base fabric is small, so that the flatness of the base fabric is obtained, and defects due to winding wrinkles are reduced. In addition, since the flatness of the base fabric is obtained, the post-processability is improved, and even when coating is required in post-processing, the coat processability is good. In addition, the quality of the woven airbag can be improved.
