上記課題を解決するために、本発明の別の態様の合成繊維用処理剤の水性液は、前記繊維用第1処理剤と、前記繊維用第2処理剤とを含んでもよい。
以下、本発明の合成繊維用処理剤(以下、処理剤ともいう)を具体化した第1実施形態を説明する。本実施形態の処理剤は、下記に示される含窒素ノニオン界面活性剤(A)を含有する。
含窒素ノニオン界面活性剤(A)は、分子中に炭素数8以上22以下の炭化水素基を有する有機アミン1モルに対し炭素数2以上3以下のアルキレンオキサイドを合計で2モル以上100モル以下付加させたものである。含窒素ノニオン界面活性剤(A)中の(ポリ)オキシアルキレン基(X)は、エチレンオキサイド及びプロピレンオキサイドを付加して形成されたものであり、且つエチレンオキサイド及びプロピレンオキサイドの総付加モル数に対するエチレンオキサイドの付加モル数の割合が50%以上である。かかる化合物により、処理剤の低泡性、乳化安定性、及び防腐性を向上させることができる。
前記(ポリ)オキシアルキレン基(X)は、製造容易性の観点より、ランダム付加であるか、又は最終付加工程がプロピレンオキサイドのブロック付加であることが好ましい。更には、最終付加工程がプロピレンオキサイドのブロック付加であることがより好ましい。
処理剤は、更に下記の非含窒素ノニオン界面活性剤(B)を含有してもよい。非含窒素ノニオン界面活性剤(B)により、処理剤が付与された繊維の濡れ性を向上させることができる。
処理剤は、更に下記のアニオン界面活性剤(C)を含有してもよい。アニオン界面活性剤(C)により、処理剤が付与された繊維がカードを通過する際のカード通過性を向上させることができる。
有機リン酸エステルの塩が適用される場合、塩としては、例えばリン酸エステルアミン塩、リン酸エステル金属塩等が挙げられる。
処理剤は、前記含窒素ノニオン界面活性剤(A)に加えて前記非含窒素ノニオン界面活性剤(B)及び前記アニオン界面活性剤(C)を含有する場合、繊維用第1処理剤及び繊維用第2処理剤の組み合わせとして構成されることが好ましい。繊維用第1処理剤は、前記含窒素ノニオン界面活性剤(A)及び前記非含窒素ノニオン界面活性剤(B)を含有する。繊維用第2処理剤は、前記アニオン界面活性剤(C)を含有する。かかる構成により、保存時の製剤安定性を向上させることができる。
(1-1)上記第1実施形態の処理剤は、所定の含窒素ノニオン界面活性剤(A)を含有する。したがって、処理剤の低泡性、乳化安定性、及び防腐性を向上できる。それにより、特に乳化液の泡由来のスカムの発生、処理剤の乳化不良によって生じた析出物由来のスカムの発生、さらには処理剤中の腐敗物由来のスカムの発生を抑制できる。よって、処理剤を用いて製造される合成繊維の生産性、品質性を向上できる。また、新たな処理剤又は再利用される処理剤をフィルタでろ過して使用する場合にフィルタの目詰まりを抑制し、生産効率を向上させることができる。
(1-3)含窒素ノニオン界面活性剤(A)及び非含窒素ノニオン界面活性剤(B)を含有する繊維用第1処理剤とアニオン界面活性剤(C)を含有する繊維用第2処理剤とから処理剤が構成される場合、保存時の製剤安定性を向上させることができる。
次に、本発明の繊維用第1処理剤(以下、第1処理剤という)を具体化した第2実施形態を説明する。以下、第1実施形態との相違点を中心に説明する。
(2-1)本実施形態の第1処理剤は、非含窒素ノニオン界面活性剤(F)及び含窒素ノニオン界面活性剤(E)を含有し、アニオン界面活性剤(G)を含有する第2処理剤と併用される。したがって、第1処理剤の製剤安定性、特に保存安定性を向上できる。また、第2処理剤との混合比率を調整することにより、得られる処理剤の成分を調整できる。
次に、本発明の第2処理剤を具体化した第3実施形態を説明する。以下、第1,2実施形態との相違点を中心に説明する。
(3-1)本実施形態の第2処理剤は、アニオン界面活性剤(G)を含有する。そして、非含窒素ノニオン界面活性剤(F)及び含窒素ノニオン界面活性剤(E)を含有する第1処理剤と併用される。したがって、第2処理剤の製剤安定性、特に保存安定性を向上できる。また、第1処理剤との混合比率を調整することにより、得られる処理剤の成分を調整できる。
次に、本発明の繊維の処理方法を具体化した第4実施形態を説明する。
本実施形態の繊維の処理方法は、第1実施形態の処理剤及び水を含有する処理剤の水性液(以下、水性液ともいう)を繊維に付与することを特徴とする。
水に、第1処理剤及び第2処理剤を添加する方法は、公知の方法を適宜採用できるが、下記の工程1及び下記の工程2を経ることが好ましい。かかる方法により、第1処理剤及び第2処理剤の混合物がエマルション形態の場合、エマルションの安定性をより向上できる。
水性液が付与される繊維の種類は、特に限定されない。繊維に付与された水性液により、最終的に処理剤が繊維表面を覆い、摩擦特性を向上させるからである。水性液が付与される繊維としては、合成繊維が挙げられる。合成繊維の具体例としては、特に制限はなく、例えば(1)ポリエチレンテレフタラート(PET)、ポリトリメチレンテレフタラート、ポリブチレンテレフタラート、ポリエチレンナフタラート、ポリ乳酸、これらのポリエステル系樹脂を含有して成る複合繊維等のポリエステル系繊維、(2)ナイロン6、ナイロン66等のポリアミド系繊維、(3)ポリアクリル、モダアクリル等のポリアクリル系繊維、(4)ポリエチレン、ポリプロピレン等のポリオレフィン系繊維等が挙げられる。これらの中で製造工程において、特に繊維間の摩擦特性の付与が必要なポリエステル繊維又はポリオレフィン繊維に適用されることが好ましい。
(4-1)本実施形態の繊維の処理方法は、処理剤の水性液を、例えば紡糸又は延伸工程等の紡績糸製造工程、仕上げ工程等において繊維に付与する方法である。特に、第2実施形態の第1処理剤と第3実施形態の第2処理剤とを水に添加して調製した水性液の場合、乳化安定性に優れる水性液が得られる。したがって、処理剤中の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又は水性液には、本発明の効果を阻害しない範囲内において、処理剤又は水性液の品質保持のため、その他の溶媒、安定化剤、制電剤、つなぎ剤、酸化防止剤、紫外線吸収剤、有機酸、上記以外の界面活性剤等の通常処理剤等に用いられる成分をさらに配合してもよい。
