溶媒(S)は、大気圧における沸点が105℃以下である溶媒である。溶媒(S)としては、水、有機溶媒が挙げられる。有機溶媒の具体例としては、エタノール、プロパノール等の低級アルコール等、ヘキサン等の低極性溶媒が挙げられる。これらの溶媒(S)は、一種類の溶媒を単独で使用してもよいし、又は二種以上の溶媒を適宜組み合わせて使用してもよい。これらの中で、第1処理剤と合成繊維用第2処理剤(以下、「第2処理剤」という)とが混合された混合物をエマルション形態とする観点から水、低級アルコール等の極性溶媒が好ましく、取り扱い性に優れる観点から水がより好ましい。
非イオン界面活性剤(C)は、分子中に(ポリ)オキシアルキレン構造を有する非イオン界面活性剤である。非イオン界面活性剤(C)としては、例えば、アルコール類又はカルボン酸類にアルキレンオキサイドを付加させたもの、カルボン酸類と多価アルコールとのエステル化合物にアルキレンオキサイドを付加させたエーテル・エステル化合物、アミン化合物としてアルキルアミン類にアルキレンオキサイドを付加させたもの等が挙げられる。これらの非イオン界面活性剤(C)は、一種類の非イオン界面活性剤を単独で使用してもよいし、又は二種以上の非イオン界面活性剤を適宜組み合わせて使用してもよい。
第1処理剤は、更に炭素数8~20の一価脂肪族アルコール(B)を含有してもよい。一価脂肪族アルコール(B)を配合することにより第1処理剤の安定性をより向上させる。一価脂肪族アルコール(B)は、不飽和結合の有無について特に制限はなく、直鎖状又は分岐鎖状の炭化水素基を有するアルコールであってもよい。
第1処理剤は、適用目的又は必要性に応じて、本発明の効果を阻害しない範囲内において、前述した成分以外のその他成分(F)、例えば多価アルコール、平滑剤として鉱物油、エステル、シリコーン化合物等、アニオン界面活性剤、キレート化剤等をさらに含有してもよい。多価アルコールの具体例としては、例えばプロピレングリコール、ジエチレングリコール、エチレングリコール、グリセリン等が挙げられる。なお、3価以上のアルコールを含有すると、高温での第1処理剤の安定性が悪くなるため、第1処理剤中に含まれる3価以上のアルコールの量は5質量%以下であることが好ましく、第1処理剤が3価以上のアルコールを含有しないことがより好ましい。高温での第1処理剤の安定性の悪化は、経時で増粘が生ずることによるものである。これは、3価以上のアルコールはそのものの粘度が高いことに加え、3つ以上の極性基が多次元的水素結合の形成に寄与するためと考えられる。
第1処理剤は、非イオン界面活性剤(E)を含有する第2処理剤と併用される。第1処理剤は、第2処理剤と別剤として構成され、使用時に第2処理剤と混合される。以下、第2処理剤について説明する。
(非イオン界面活性剤(E))
非イオン界面活性剤(E)は、第1処理剤と第2処理剤の混合物の安定性を向上させ、混合物の合成繊維への均一付着性を向上させる。非イオン界面活性剤(E)は、混合物のエマルションの安定性及び混合物の合成繊維への均一付着性に優れる。
溶媒(T)の具体例は、第1処理剤に配合される溶媒(S)において例示したものが挙げられる。これらの中で、混合物をエマルション形態とする観点から水、低級アルコール等の極性溶媒が好ましく、取り扱い性に優れる観点から水がより好ましい。
有機リン酸エステル化合物(D)は、第1処理剤に配合されるリン酸化合物(A)において挙げた有機リン酸エステル化合物の例を適用できる。
第2処理剤は、適用目的又は必要性に応じて、本発明の効果を阻害しない範囲内において、前述した成分以外のその他成分(G)、例えば上述した一価脂肪族アルコール(B)、多価アルコール、平滑剤として鉱物油、エステル、シリコーン化合物等、キレート化剤等をさらに含有してもよい。
次に、本発明の合成繊維用処理剤を具体化した第2実施形態を説明する。

(1-1)上記実施形態の第1処理剤は、所定のリン酸化合物(A)及び溶媒(S)を含有し、所定の量の所定の非イオン界面活性剤(C)を任意選択でさらに含有する。また、合成繊維用処理剤は、第1処理剤と、非イオン界面活性剤(E)を含有する第2処理剤とが、別剤として保存され、使用時に混合される。したがって、合成繊維用処理剤を構成する第1処理剤及び第2処理剤の安定性、特に保存安定性を向上できる。第1処理剤中において、非イオン界面活性剤と有機リン酸化合物との含有比率が所定の範囲に規定されるため、第1処理剤の安定性が向上される。さらに、第1処理剤は、使用時に第2処理剤と混合されるため、界面活性剤によりエマルジョン形態の混合物の安定性も向上できる。したがって、リン酸化合物(A)等の成分の繊維への均一な付着性を低下させることがない。よって、合成繊維用処理剤中に含まれるリン酸化合物(A)等の成分により制電性等の効能を有効に発揮できる。
次に、本発明の合成繊維用処理剤の水性液の調製方法(以下、「水性液の調製方法」という)を具体化した第3実施形態を説明する。

・本実施形態の水性液の調製方法において、水性液を調製する前記第1の工程及び第2の工程から選ばれる任意の工程において、さらにシリコーン組成物を加えることが、繊維製造時の消泡性、繊維の紡績性能向上等の観点から好ましい。シリコーン組成物の具体例としては、特に限定されないが、例えばポリジメチルシロキサン、ポリオキシエチレン変性シリコーン等が好ましい。シリコーン組成物の添加は、水性液の安定性の観点から、第2の工程において行われるのがより好ましい。
次に、本発明の合成繊維の処理方法を具体化した第4実施形態を説明する。
本実施形態の合成繊維の処理方法は、水に、第1処理剤及び第2処理剤を添加して得られた合成繊維用処理剤の水性液を、例えば紡糸又は延伸工程、仕上げ工程等において合成繊維に付与する方法である。水性液の調製方法は、第3実施形態の水性液の調製方法を採用できる。合成繊維に付着した水性液は、乾燥工程により水分を蒸発させてもよい。
(3-1)本実施形態の合成繊維の処理方法は、合成繊維用処理剤の水性液を、例えば紡糸又は延伸工程、仕上げ工程等において合成繊維に付与する方法である。したがって、合成繊維用処理剤中の各成分の合成繊維への均一な付着性を低下させることがなく、各成分による短繊維、紡績糸、不織布等に対する効能を有効に発揮できる。
・上記実施形態の各処理剤には、本発明の効果を阻害しない範囲内において、処理剤の品質保持のための安定化剤、制電剤、つなぎ剤、酸化防止剤、紫外線吸収剤等の通常処理剤に用いられる成分をさらに配合してもよい。

また、不揮発分から検出されるイオン濃度、第1処理剤の酸価、30℃における粘度は、表2の「不揮発分から検出されるイオン濃度」欄、「酸価」欄、「30℃における粘度」欄にそれぞれ示す。第1処理剤の酸価と粘度は、下記に示される方法により測定した。また、不揮発分から検出されるイオン濃度は、下記に示されるICP発光分析法により測定した。
JIS K 0070-1992「3.2電位差滴定法」により測定した。なお、試料のサンプリング量は、10gとし、溶媒はエタノール/キシレン=1/2の混合溶媒を使用した。
容量300mLのトールビーカー(高さ13.5cm)に、250gの試料を加える。試料はあらかじめ30℃に温調しておき、30℃のウォーターバスを使用して温度を保持したまま測定する。東京計器社製デジタルB型粘度計DVL-B型を使用し、操作マニュアルに従いながら、粘度に応じて最適なローター及び回転数を選択しながら測定を行った。
まず、第1処理剤を不揮発分濃度が0.1%となるように蒸留水を用いて希釈する。Ca,K,Mg,Na,P,Siの標準溶液として、それぞれ濃度既知の0.5ppm、1ppm、5ppm、10ppmの溶液を用意する。上記を用いた測定で、10ppm以上の値が出る場合、再度10ppm、50ppm、100ppm、500ppmの溶液を標準溶液として測定する。また、0ppmの標準溶液として、サンプル希釈に使用した蒸留水を使用する。上記を用いた測定で、検量線の上限を外れる場合は、サンプルを蒸留水で更に10倍希釈して測定を実施する。ICP発光分析装置(島津製作所社製ICPE-9000)にて測定した。

○(可):沈殿量が0.3mL超0.5mL以下
×(不可):沈殿量が0.5mL超

試験区分6で得た処理済みポリエステルステープル繊維20gを、20℃で65%RHの恒温室内で24時間調湿した後、ミニチュアカード機に供した。投入量に対して排出された量の割合を算出し、下記の評価基準で評価した。結果を表4,5の「カード通過性」欄に示す。
◎(良好):排出量が90%以上

◎(良好):スカムが全く堆積していない場合
○(可):スカム堆積量がシリンダー表面積の2%未満
×(不良):スカム堆積量がシリンダー表面積の2%以上
試験区分9(制電性の評価)
試験区分6で得た処理済みポリエステルステープル繊維20gを用い、25℃×40%RHの雰囲気下でミニチュアカードに供した。紡出されたカードウェブの静電気をデジタル静電電位測定器を用いてカードウェブから1cm離れた位置から測定し、制電性を下記の基準で判定した。結果を表4,5の「制電性」欄に示す。
◎(良好):静電気発生量が0.3kV未満
○(可):静電気発生量が0.3kV以上0.6kV未満
×(不良):静電気発生量が0.6kV以上
比較例7~44の合成繊維用処理剤は、いずれもリン酸化合物(A)及び非イオン界面活性剤(E)が本発明の範囲から外れる配合比率で、予め混合して調製されている。比較例7~44の合成繊維用処理剤は、いずれも保存安定性に劣ることが確認された。一方、本発明の第1処理剤によると、表2の保存安定性の評価結果からも明らかなように、保存安定性を向上できる。また、かかる第1処理剤を含んで構成される合成繊維用処理剤が付与された繊維は、カード通過性が向上され、スカム抑制効果、制電性が向上され、各種機能を十分に発揮できる。なお、各例の合成繊維用処理剤をポリオレフィン樹脂としてポリエチレン樹脂に適用した場合も同様の効果、つまりカード通過性、制電性等を向上させる効果が得られることを確認している。
