Description
[1]架橋構造を有し、かつカルボキシル基を有する基材繊維に金属被膜を形成すべき金属の金属イオン及び/又は金属錯イオンを導入した後、該イオンを還元糖類により還元し金属被膜を形成せしめた繊維であり、かつ該繊維の引張伸度と結節強度の積が12以上であることを特徴とする導電性繊維。
[2]10回洗濯後の単糸の体積抵抗率が100Ω・cm以下であることを特徴とする[1]に記載の導電性繊維。
[3]20℃65%RHにおける飽和吸湿率が5重量%以上であることを特徴とする[1]又は[2]に記載の導電性繊維。
[4]金属被膜を形成せしめた後、防錆剤による防錆加工処理を施したことを特徴とする[1]〜[3]のいずれかに記載の導電性繊維。
[5][1]〜[4]のいずれかに記載の導電性繊維を含有することを特徴とする繊維構造体。
JIS L 1015 8.7引張強さ及び伸び率 8.7.1標準時試験に従い、伸び率として算出された値を、引張伸度(%)とした。
(2)結節強度(cN/dtex)
JIS L 1015 8.8結節強さ 8.8.1標準時試験に従い、結節強さとして算出された値を、結節強度(cN/dtex)とした。
(3)体積抵抗率(Ω・cm)
20℃、40%RHの雰囲気中で、導電性繊維の単糸1本を伸長せずにまっすぐに伸ばし、両端に電極を接続し、デジタルマルチメーターで端子間抵抗値(Ω)を測定した。次いで、単糸の繊維長(cm)と断面積(cm2)から、体積抵抗率(Ω・cm)を算出した。単糸の繊維長は、単糸1本を伸長せずにまっすぐに伸ばし、置尺上で繊維長を測定した。断面積は、導電性繊維断面の電子顕微鏡写真より測定した。
(4)飽和吸湿率(%)
試料繊維約5.0gを熱風乾燥機で105℃、16時間乾燥して重量を測定する(W1g)。次に試料を温度20℃で65%RHの恒湿槽に24時間入れておく。このようにして飽和吸湿した試料の重量を測定する(W2g)。以上の測定結果から、次式によって算出した。
飽和吸湿率(%)={(W2−W1)/W1}×100
(5)カルボキシル基量(mmol/g)
十分乾燥した試料繊維約1gを精秤し(Xg)、これに200mlの水を加えた後、50℃に加温しながら1mol/l塩酸水溶液を添加してpH2にし、次いで0.1mol/l水酸化ナトリウム水溶液で常法に従って滴定曲線を求めた。該滴定曲線からカルボキシル基に消費された水酸化ナトリウム水溶液消費量(Yml)を求め、次式によってカルボキシル基量(mmol/g)を算出した。
カルボキシル基量(mmol/g)=0.1Y/X
(6)洗濯耐久性(Ω・cm)
試料繊維をJIS L0217 番号103(洗剤は花王株式会社製アタック(登録商標)使用)に記載の方法で10回繰り返し洗濯処理した後、(3)の方法で単糸の体積抵抗率を測定した。
AN90%、アクリル酸メチル10%からなるAN系重合体(30℃ジメチルホルムアミド中での極限粘度[η]:1.2)10部を48%のチオシアン酸ナトリウム水溶液90部に溶解した紡糸原液を、定法に従って紡糸、延伸した後、乾燥して、短繊維繊度3.3dTexの原料繊維を得た。該原料繊維をヒドラジンヒドラート15%水溶液に浴比1:10で浸漬し、110℃で1時間架橋導入処理を行った。架橋導入処理後の窒素増加量は、1.0%であった。なお、窒素増加量は、原料繊維と架橋導入処理後の繊維について元素分析で窒素含有量を求め、その差から算出した。次いで架橋導入処理後の繊維を水酸化ナトリウムの1%水溶液中で、95℃で1時間加水分解処理を行い、水洗、乾燥した。得られた繊維はカルボキシル基を1.7mmol/g含有していた。
非鉄金属用水溶性防錆添加剤に変えて銀変色防止剤(ニューダインシルバー:大和化成製)を使用する以外は実施例1と同様にして実施例2の導電性繊維を作製した。得られた繊維の評価結果を表1に併記した。
防錆処理加工を行わないこと以外は実施例1と同様にして実施例3の導電性繊維を作製した。得られた繊維の評価結果を表1に併記した。
グルコースの10%水溶液に45℃で1時間浸漬する代わりにヒドラジンヒドラート2%水溶液に25℃で1時間浸漬すること以外は実施例1と同様にして実施例4の導電性繊維を作製した。得られた繊維の評価結果を表1に併記した。
グルコースの10%水溶液に45℃で1時間浸漬する代わりにヒドラジンヒドラート2%水溶液に25℃で1時間浸漬すること及び防錆加工処理を行わないこと以外は実施例1と同様にして実施例5の導電性繊維を作製した。得られた繊維の評価結果を表1に併記した。
実施例1で作製した原料繊維を、ヒドラジンヒドラート30%水溶液に浴比1:10で浸漬し、100℃で3時間架橋処理を行った。架橋導入処理後の窒素増加率は、1.6%であった。次いで、架橋導入処理後の繊維を水酸化ナトリウムの1%水溶液中で、95℃で3時間加水分解処理を行い、水洗、乾燥した。得られた繊維はカルボキシル基を3.0mmol/g含有していた。次に、得られた繊維を5%塩化亜鉛水溶液で、20℃、30分間処理し、基材繊維を作製した。
