精練温度:110℃
浴比:1/20
処理水:3°DH
木綿生機を上記の条件で精練処理し、処理後の布から幅3cm、長さ15cmのサンプル布を切り取り、染料を溶解した水溶液を満たしたバット上にサンプル布の一端が浸るように、たるみがない状態で鉛直に吊るし、15分後の染料水溶液の吸い上げ高さ(mm)を測定することで調べた。吸い上げ高さが高いほど、湿潤性に優れ、精錬剤の精練性が優れることを示す。
精練処理生地から、5cm×5cmの試験試料を切り出し、水平に置き、試料生地の上約1cmから、吸い上げの高さの評価で使用した染料水溶液をスポイトで0.1mL落下させる。自然乾燥後、染料水溶液の拡がり形で、吸水性を判定する。評価基準は次の通りである。
○:染料が大きい円状に拡がり、染色された範囲に直径1cmの円が納まる。
△:染料の拡がりが不十分、あるいは染料の拡がりの形が歪であり、染色された範囲に直径7mmの円は納まるが、1cmの円は納まらない。
×:染色された範囲に直径7mmの円が納まらない。
1Lのメスシリンダーに試験液(非イオン性界面活性剤濃度;2.00×10-3モル/L、残部は水)を200mL入れ、ボールフィルタを付けたエアポンプによりメスシリンダーの底部より1.5L/分のエアーを曝気し、2分後の泡立ちの高さ(mm)を測定した。
花王(株)社製 エマール 270Jを用いた。
2000mLの反応容器に、協和発酵ケミカル(株)製デカノール(化学名:イソデカノール)1モルにエチレンオキサイド3モル付加して得られた有機ヒドロキシ化合物(平均分子量=158.3)633.2g(4.00モル)及び85%のオルトリン酸93.7g(P2O5・nH2Oとして表すとP2O5;0.41モル、H2O;2.00モル)を入れ、攪拌・混合し、温度を50~70℃に保ちながら五酸化リン(有効分98.5%)229.6g(1.59モル)を徐々に添加した後、80℃に昇温し12時間反応を行った。その後、この反応生成物を強制薄膜による水蒸気蒸留装置(伝熱面積;0.03m3、ガラス製)を用いる脱臭処理に供した。水蒸気蒸留は、ジャケットの温度150℃、2.7kPa(絶対圧)で、反応生成物とスチームを、それぞれ100g/hr、75g/hrの速度で連続的に供給して行い、残さとして有機ヒドロキシ化合物含量0.8%及び水分0.3%を含むリン酸エステルを得た。その後このリン酸エステルを所定量の水酸化ナトリウム水溶液に添加・攪拌しながら中和を行い、ポリオキシエチレン(平均付加モル数3.0)イソデシルセスキホスフェート・Na塩を得た。
表2の処方に従い各種精練剤組成物を調製し、下記の方法に従って各組成物の流動性の評価を行った。なお、表では(A)成分に該当しない非イオン性界面活性剤も便宜的に(A)成分として示した。
内径24.3mm、高さ46.5mmのサンプル管(マルエム社製サンプルバイアルNo.3)中に、組成物3mLを入れ、3℃で30分間静置した。その後、組成物の入ったサンプル管を倒置して、気泡の上昇にかかる時間(秒)を測定した。評価基準は次の通りである。
○:1秒未満
△:1秒以上20秒未満
×:20秒以上
