Description
厚さは、マイクロメーターにより測定した。
JIS L 1018 カットスリップ法に準拠して測定した。なお、測定条件としては、引張速度20cm/分、つかみ間隔20cm、試料幅5cm、試験機:定速伸張形とした。
JIS L1018 A法(45°カンチレバー法)に準拠して、カンチレバーソフトネステスター(型式:CAN-45)により測定した。
得られた試験片を、四探針式低抵抗率計(ロレスタGP、三菱化学製)を用いて表面9箇所の抵抗(Ω)を測定し、同抵抗計により体積抵抗率(Ω・cm)に換算し、平均値を算出した。
堀場ジョバンイボン製LabRam800を用い、アルゴンレーザーの514nmの波長を用いて測定した。
マックサイエンス製TG−DTAを用い、空気を0.1リットル/分の流速で流通させながら、10℃/分の速度で昇温し、燃焼挙動を測定した。燃焼時にTGは減量を示し、DTAは発熱ピークを示すので、発熱ピークのトップ位置を燃焼開始温度と定義した。
アンモニア、ホルムアルデヒド、トリメチルアミン、および硫化水素に対する吸収性能を調べた。まず、得られた炭素化繊維から秤量6gのサンプル片を作製した。このサンプル片を、ガス容量13Lのデシケーター中に入れ、これに各ガスを後述する表1に示す初期濃度となるように入れ、ガス濃度の経時的変化を検知菅にて測定した。なお、比較のために、竹炭6g、備長炭6gを用い、同様のガス吸着試験を行った。
財団法人繊維評価協議会に定められる統一試験方法に従い、メチシリン耐性黄色ブドウ球菌(MRSA IID 1677)に対する抗菌性を調べた。
(静菌活性値)= Mb−Mc≧ 2.2、 但し、Mc≠0 であること
Mb:標準布(ナイロン標準白布)の18時間培養後の3検体の生菌数の常用対数値の平均値
Mc:抗菌加工布(本実施例においては炭素化繊維布帛)の18 時間培養後の3検体の生菌数の常用対数値の平均値
(殺菌活性値)= Ma−Mc >0
Ma:標準布(ナイロン標準白布)の試験菌接種直後の3検体の生菌数の常用対数値の平均値
(製造条件)
以下の条件により炭素化繊維布帛を調製した。
加熱条件:室温(15℃±20℃)〜600℃ 昇温速度 100℃/時間
総合加熱保持時間 15時間
冷却: 自然冷却
得られた炭素化繊維布帛の表面性状を電子顕微鏡を用いて観察した。得られた結果を図1A(倍率50倍)、図1B(倍率3000倍)、図1C(倍率10000倍)に示す。
体積固有抵抗: ∞Ωcm
引張強度: ウェール方向3.63N、コース方向2.27N
カンチレバーソフトネステスターにより測定される剛軟度: ウェール方向18mm、コース方向17mm
厚さ:4mm
単位面積当りの質量:55.2g/m2
空気中での燃焼開始温度:439℃
D/G比:0.8
なお、図2に、空気中での燃焼開始温度を求めたTG−DTAチャート、図3に、D/G比を求めたラマンスペクトルチャートを示す。
