Abstract
Description
1.合成繊維製織物の一方の面にシリコーン系樹脂がコートされたシリコーンコート布であって、シリコーン系樹脂がコートされた面に熱可塑性樹脂が付着しており、シリコーン系樹脂がコートされた面同士の接着強度が0.01~10N/cmであるシリコーンコート布。
2.熱可塑性樹脂の融点が50~200℃である上記1記載のシリコーンコート布。
3.シリコーンコート布のシリコーン系樹脂の塗布量が10~200g/m2である上記1または2に記載のシリコーンコート布。
4.上記1~3のいずれかに記載のシリコーンコート布を用いたエアバッグ。
シリコーンコート布のシリコーン系樹脂がコートされた面に付着している熱可塑性樹脂を約5mgサンプリングパンに投入した。DSC-Q100(TAInstruments製)にて空気流100ml/分の雰囲気下で5℃/分の昇温速度で溶融させ吸熱曲線を得て、最大の吸熱ピークを融点とした。
JIS L1096(2010) 8.26.1 A法 フラジール形法により測定した。
サンプルがシリコーンコート布の場合は、熱可塑性樹脂が付着したシリコーンコート布から、幅5cm、長さ5cm以上の同じ大きさの測定試料を2枚切出した。切り出した2枚の試料の熱可塑性樹脂が付着したシリコーン系樹脂がコートされた面同士を重ね合わせ、引張試験機のチャックで掴めるように両端2cmを残して金属製のプレートで挟み、1kgの錘を乗せて、熱可塑性樹脂の融点±10℃のオーブン内に30分間静置し、その後オーブンから取り出した後、錘を乗せたままで20℃で60分間冷却して剥離用試料を作製した。作製した剥離用試料をRTM-500で速度500mm/minで接着部分を剥離し、得られたチャートから最大値を読み取り、その値を試料幅5cmで割り返した値を接着強度とした。
熱可塑性樹脂が付着したシリコーンコート布を経15cm×緯30cmに切出し、蛇腹状に熱可塑性樹脂が付着したシリコーンコート面同士が重なるように、経糸と平行に6回折り返したサンプル(図4参照)を、直径45mmの金属製容器に詰め込み、上から直径45mmの1kgの金属製錘を乗せて、150℃のオーブン内に30分静置し、その後オーブンから取出した後、錘を乗せたままで20℃で30分間冷却したのち、サンプルを金属製容器から取出し、引き続き20℃で30分間静置した。静置後のサンプルの最も幅が広い部分を測長し、コンパクト性を評価した。
トータル繊度470dtex、72フィラメントのナイロン6.6マルチフィラメント繊維を平織にてウォータジェットルームにて製織後、沸水にて収縮加工し、110℃で乾燥仕上げを行った。得られた織物は、経糸および緯糸方向の織密度が46本/2.54cmであった。
