（繊維処理剤の分散性の評価）
実施例及び比較例で用いられる繊維処理剤と同様の組成の繊維処理剤について分散性を評価した。まず、ノニオン系界面活性剤を５０℃の水に添加した後、５０℃、３００ｒｐｍの条件で約３時間撹拌した。その後、カチオン系界面活性剤を添加した後、５０℃、３００ｒｐｍの条件でおよそ６時間撹拌し、繊維処理剤の状態を目視で観察した。２相に分離することなく、水への添加前に固体であった成分が全体的にコロイド状に分散している場合を「Ａ」と評価し、水への添加前に固体であった成分が全体的にコロイド状に分散しない場合（２相に分離する場合を含む）を「Ｂ」と評価した。結果を各表に示す。カチオン系界面活性剤を用いていない比較例１については、分散性に問題がないことから「Ａ」と評価した。比較例４については、ノニオン系界面活性剤を用いることなくカチオン系界面活性剤の分散性を確認したところ、「Ｂ」と評価される結果であった。 (Evaluation of dispersibility of fiber treatment agent)
Dispersibility was evaluated for fiber treatment agents having the same composition as the fiber treatment agents used in Examples and Comparative Examples. First, after adding a nonionic surfactant to water at 50°C, the mixture was stirred at 50°C and 300 rpm for about 3 hours. Then, after adding the cationic surfactant, the mixture was stirred at 50° C. and 300 rpm for about 6 hours, and the state of the fiber treatment agent was visually observed. An ingredient that was solid prior to addition to water was rated "A" if the ingredient that was solid prior to addition to water was generally colloidally dispersed without separating into two phases. was evaluated as "B" when it did not disperse colloidally throughout (including cases where it separated into two phases). Results are shown in each table. Comparative Example 1, in which no cationic surfactant was used, was evaluated as "A" because there was no problem with dispersibility. Regarding Comparative Example 4, when the dispersibility of the cationic surfactant was confirmed without using a nonionic surfactant, the result was evaluated as "B".
