- Airbags reduce the impact of collisions during accidents and the contact between in-vehicle equipment and the human body. Airbags need to be airtight because they are deployed quickly and receive the human body without tearing and need a cushioning effect. Specifically, the airtightness of the boundary between the inflatable part and the non-inflatable part affects the airtightness of the entire bag, but the airtightness of the aforementioned part is particularly important especially in an environment where high-temperature gas is present when the inflator is activated. is there. Improvement of the airtightness of the base fabric is disclosed in Patent Document 1 and Patent Document 2 below. Patent document 1 is a method of suppressing the movement of the yarn by improving the mutual restraining force between the fibers.

(10)製織後1N/cm以上の張力下で湿潤処理されていることを特徴とする上記1~9項のいずれか一項に記載のノンコートエアバッグ基布。
(11)上記1~10項のいずれか一項に記載の基布にて製造されたノンコートエアバッグ。
本発明の基布の織密度は、カバーファクターが2250以上2500以下を満足する範囲であることが必要である。カバーファクターが2300以上2500未満であればより好ましく、2350以上2450未満が最も好ましい。2250以上であれば、エアバッグとしたときの膨張部と非膨張部の境界部分の目開きが大きくなって、通常圧の気密性が損なわれることがない。2500以下ならば、柔軟性が損なわれることがない。基布の嵩密度は700kg/m3以上900kg/m3以下が必要である。750kg/m3以上900kg/m3未満であればより好ましく、750kg/m3以上850kg/m3未満であればさらに好ましく、780kg/m3以上830kg/m3が最も好ましい。700kg/m3以上であれば、バッグとしたときの膨張部と非膨張部の境界部分の目開きが大きくならず、高圧の気密性が損なわれることがない。また、900kg/m3以下の場合は柔軟性が損なわれず、収納性も小さく維持される。カバーファクターと嵩密度を上記の範囲にするには、例えば、経糸の密度を50本/inch以上に設定し、また緯糸も同じ密度の設定を行ない、製織時の経糸の張力を0.3cN/dtex以上の張力で製織し、その後にセット工程を行なうことによって可能である。セット時には基布を弛めずに処理することが重要で、その時の張力は1N/cm以上である。すなわち、カバーファクターを大きくし、かつ、嵩密度を大きくし、3次元的に目の詰まった織物構造とするための加工条件を採用することが重要である。
本発明の基布の100℃における縫目目開きは、12mm以下である。好ましくは10mm以下であり。8mm以下であれば最も好ましい。12mm以下であればバッグとしたときの気密性を大きく損なうことなく、展開が可能である。なお、縫目目開きの測定方法は後述する。
本発明の基布は、引裂き強力が150N以上300N未満であることが好ましい。より好ましくは180N以上で200N以上であれば最も好ましい。150N以上では目ずれ抑制に有利に働く。また300N未満の基布であれば繊維の自由度が大きく柔軟な基布となり、収納性に有利になる。ここでの引裂き強力はISO13937-2に規定されているシングルタング法である。
アルキルリン酸エステル塩とアルキル硫酸塩は、いずれかが上述の適量存在することが好ましい。しかし、両者がともに存在することが好ましく、より少量の存在量でより効果的である。
アルキルリン酸塩のアルキル部は炭素数が8以上18以下であることが好ましく、側鎖を有していてもよく、またエチレンオキサイド鎖を含んでも良い。塩としては、ナトリウム塩、カルシウム塩、3級アミン塩が好ましい。アルキル硫酸塩のアルキル部は炭素数が8~18であることが好ましく、側鎖を有していてもよく、またエチレンオキサイド鎖を含んでも良い。塩としてはナトリウム塩、カルシウム塩が好ましい。
また、塗布する液体の形態としては、炭化水素等の有機溶媒や水への分散液もしくは溶液の形態が可能であるが、好ましくは溶媒に水を利用したものが経済的、安全性にも有効である。なお、繊維表面とは、基布を構成する繊維の単糸表面を指す。
本発明の基布に使用する繊維は、その構成する単糸断面は丸断面が好ましい。丸断面であれば、基布に応力がかかる場合において、均等に応力がかかる為に、引裂き、引張強力の高い基布を得ることができる。ここでの丸断面とはアスペクト比が1.0以上1.1未満の事を言い、アスペクト比の長軸の定義はその断面の最大径、短軸の定義は最小径を示す。
本発明の基布に使用する繊維素材は、熱可塑性繊維が好ましく、特にポリエステル、ポリアミド66繊維が繊維物性、取扱い性にて最も好適に使用できる。
(1)製織性は、豊田自動織機社製LWT710を用い、2.3m幅、織機回転数600rpmまたは500rpmで試織を行い、下記基準で評価した。
停台が5回/日以上:×
停台が3~4回/日:△
停台が2回/日未満:○
(3)基布の引裂き強力はISO13937-2に従って測定した。
(4)基布の動的通気量はASTM-D6476に従ってTEXTEST社製FX3350通気量試験機を用いて測定し、テストヘッドが400cc、ピーク圧力が95~105kPaになるようにして、50kPa時の通気量を求めた。
(5)基布の嵩密度は10cm2の基布重量及び厚み(ISO-5084 試験圧1kPa)を測定し、その重さと体積によって算出した。
(7)100℃における縫目開き量は、室温の縫目開き量測定と同じ試料を作成し、100℃に設定した専用恒温槽の中1分間保持後、上記(5)と同様に1500Nの荷重をかけた時の縫目目開き長さを定規にて測定した。
(9)繊維表面のアルキルリン酸エステル塩の付着量はICPによってリン濃度より求めた。
(10)繊維表面のアルキル硫酸塩の付着量はイオンクロマトグラフによって硫酸根の量より求めた。
(11)外観は、仕上がった基布を目視判定し、特に問題ない場合を○、外観で異常を発見した場合はその現象を記した。
(12)総合判定は縫目目開き量を主体にして、柔軟性(硬さ)および気密性(動的通気量)も考慮して判定し、極めて良好を○、良好を△、不良を×とした。
