(4)吸水性
JIS L1018A法(滴下法)による吸水性を測定した。60秒以下を合格とする。
(5)汚れの洗濯除去性
ダイヤペースト法(日本化学繊維協会規格 JCFA TM-104)に従って汚れの洗濯除去性(防汚SR性)を評価した。すなわち、水平に敷いたろ紙の上に試験片(前記L-0布または前記L-20布)を広げ、これに下記の汚れ成分を0.1mL付着させて、室温で一時間放置した。
(汚れ成分)
カーボンブラック 0.167質量部
流動パラフィン 0.625質量部
牛脂硬化油 0.208質量部
モーターオイル(Shell製) 100質量部
次に、この試験片を、2槽式電気洗濯機を用いて15分間洗濯(浴比1:30、液温40℃、温水30Lに対する洗剤アタック(商品名、花王(株)製)の量25g)を入れ、濯ぎ、脱水を行なった後、風乾した。乾燥した試験片に残存するシミの状態を汚染用グレースケール(JIS L 0805:2005)により判定した。
還流冷却管、窒素導入管、温度計および撹拌装置を備えた100ml四つ口フラスコに含フッ素モノマー CH2=CHC(=O)O-CH2CH2C6F13を18.6g、ポリエチレングリコールアクリレート CH2=CHC(=O)O-(CH2CH2O)n-H(BLEMMER AE90、日油株式会社製、nの平均値は2、以下、AE90(b)と記す)を11.4g、2-メルカプトエタノールを0.3gとメチルエチルケトン(以下、MEKと記す)を45g仕込んで、30分間窒素バブリングした。窒素気流下で内温を50-65℃に昇温後、パーブチルPV(以下、PVと記す)を0.4g添加し、60から65℃で6時間反応させた。得られた溶液を減圧条件下にて約70℃でMEKを留去し、淡黄色ポリマー残渣を得た後、水を122.4g添加し、内温を約80℃で1hr以上保った後、冷却してフッ素系化合物の固形分濃度が約20重量%の水分散液を調整した。
実施例1において、処理液に下記の4級アンモニウム塩0.1%併用すること以外は実施例1と同様にした。
実施例1において、処理液に下記の4級アンモニウム塩0.1%併用すること以外は実施例1と同様にした。
実施例1において、処理液に含まれるフッ素含有化合物としてフッ素系撥水加工剤(日華化学NDN-7E、固形分濃度 20重量%)を用いる以外は実施例1と同様に行った。該布帛に対するフッ素含有高分子の割合は1重量%であった。
