［従来の技術］
近年、各種交通機関の乗員の保護用として、シートベル

バッグシステムが実用化され始めている。[Prior Art] In recent years, seat belts have been commonly used to protect occupants of various types of transportation, and even safer airbag systems have begun to be put into practical use.
通常エアバッグは原糸を製織後、ゴムを積層し、折りた
たまれて格納されており、事故などのショックを受ける
と、高圧カスにより瞬時に膨張し、乗ｎの安全を図るよ
う設置されている。Normally, airbags are made by weaving yarn and then layering rubber, which is then folded and stored. When the bag receives a shock such as an accident, it instantly inflates due to high-pressure waste, ensuring maximum safety. .
しかるにエアバッグとして重要な特性は、瞬間的な膨張
に耐え得る耐衝撃性、長期保管中の耐久性、高圧カスの
通気性の阻止性か高いことおよび、コンパクトに格納で
きることなど挙げることかできる。However, important properties for airbags include impact resistance that can withstand instantaneous inflation, durability during long-term storage, high resistance to air permeability of high-pressure debris, and the ability to be stored compactly.

６４−４１４３９号公報の公知例で見られるように、現
在エアバッグに用いられている繊維は、ナイロン−６６
であり、ポリエステル繊維は使用されていないのが実情
である。For example, as seen in the publicly known examples of JP-A-64-41438 and JP-A-64-41439, the fibers currently used in airbags are nylon-66
The reality is that polyester fibers are not used.
即ちポリエステル繊維では耐衝撃性に問題があり使用出
来なかったのである。That is, polyester fibers could not be used because of their impact resistance problems.

A method of laminating rubber elastomers and urethane resins has been proposed in Japanese Unexamined Patent Publication No. 47692 and Japanese Utility Model Application Publication No. 4924108.
さ゛らに接着性を確保するために、現在はゴム糊を人手
で塗布する方法がとられており、ゴム糊中の溶媒が飛散
し大きな環境問題となっているのである。In order to further ensure adhesion, rubber glue is currently applied manually, which causes the solvent in the rubber glue to scatter, creating a major environmental problem.

Nylon 66 fibers had poor impact resistance and were not used as fibers for airbags.On the other hand, nylon 66 fibers were inferior in heat and humidity resistance and light resistance, resulting in poor durability for airbags.

The lamination method described in the publication does not satisfy the adhesion between the base fabric used in the airbag and the laminate. Due to the poor adhesion between the base fabric and the laminate, when it is folded and stored in a small size such as an airbag, it not only has poor foldability and is too bulky to be stored in a small size, but also the base fabric is partially folded when stored. A phenomenon of separation between the cloth and the rubber or resin is observed, making it impossible to completely block high-pressure debris during a collision, and making it impossible to absorb energy during a collision.

テル繊維は通常編織物として使用されるため、結節強度
を４．１ｇ／ｄ以上、乾熱収縮率を１０％以下とするこ
とにより、編織物の引裂き強力、平坦性、均一性を向上
することかできる。Since the polyester fiber used in the impact-absorbing airbag according to the present invention is usually used as a knitted fabric, the knot strength is set to 4.1 g/d or more and the dry heat shrinkage rate is 10% or less to prevent tearing of the knitted fabric.

るため格納容積が増大するのである。The dry heat shrinkage rate is preferably 7.0% or less, more preferably 5.0% or less. If the dry heat shrinkage rate is high, especially if it exceeds 10%, the flatness and uniformity of the knitted fabric cannot be maintained, which not only reduces shock absorption, but also causes poor adhesion when laminating rubber etc. in post-processing. Therefore, when stored for a long period of time, the knitted fabric and the rubber layer may peel off, resulting in a problem of reduced impact resistance. Furthermore, if the flatness and uniformity are poor, the foldability will be poor and the bulk of the airbag will increase, resulting in an increase in storage volume.
