Description
本発明が解決しようとする課題は、耐炎化処理工程における耐炎化繊維の集束性を向上させることにある。
前記オニウム塩は、分子中のリン原子に結合している置換基の全てが炭素数3以上のアルキル基である有機硫酸ホスホニウム塩、及び分子中のリン原子に結合している置換基の全てが炭素数3以上のアルキル基である有機スルホン酸ホスホニウム塩から選ばれる少なくとも一つを含むことが好ましい。
前記非イオン界面活性剤は、炭素数4〜20の脂肪族飽和アルコール1モルに対し、エチレンオキサイドを1〜20モルの割合で付加させたものを含むことが好ましい。
以下、本発明の炭素繊維前駆体用処理剤(以下、単に処理剤という)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に含有される平滑剤としては、例えば、シリコーン、エステル等が挙げられる。
なお、平滑剤は、アミノ変性シリコーンを含む。アミノ変性シリコーンのアミノ当量は、例えば、500〜10000g/molであることが好ましい。平滑剤がアミノ変性シリコーンを含む場合には、処理剤が付与された炭素繊維前駆体から得られた炭素繊維の強度が向上する。また、平滑剤は、アミノ変性シリコーン及びポリエーテル変性シリコーンを含むことがより好ましい。この場合には、後述する紡糸工程における集束性が向上するとともに、後述する耐炎化処理工程における集束性が更に向上する。
(B)特定のオニウム塩
本実施形態の処理剤に含有される特定のオニウム塩は、有機硫酸ホスホニウム塩、有機スルホン酸ホスホニウム塩、分子中に炭素数が3以上のアルキル基を有する有機硫酸の4級アンモニウム塩、分子中に炭素数が3以上のアルキル基を有する有機スルホン酸の4級アンモニウム塩から選ばれる少なくとも一つである。
なお、特定のオニウム塩は、有機硫酸ホスホニウム塩及び有機スルホン酸ホスホニウム塩から選ばれる少なくとも一つを含むことが好ましい。また、特定のオニウム塩は、分子中のリン原子に結合している置換基の全てが炭素数3以上のアルキル基である硫酸ホスホニウム塩、及び分子中のリン原子に結合している置換基の全てが炭素数3以上のアルキル基である有機スルホン酸ホスホニウム塩から選ばれる少なくとも一つを含むことがより好ましい。この場合には、処理剤を付着させた炭素繊維前駆体に制電性を付与できる。
本実施形態の処理剤に含有される非イオン界面活性剤としては、特に制限はなく、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が挙げられる。
非イオン界面活性剤は、1種を単独で使用してもよく、2種以上を組み合わせて使用してもよい。
本実施形態の処理剤は、本発明の効果を阻害しない範囲内において、通常処理剤に用いられるその他成分をさらに含有してもよい。その他成分としては、例えば、つなぎ剤、酸化防止剤、紫外線吸収剤等の処理剤の品質保持のための安定化剤や制電剤が挙げられる。その他成分は、1種を単独で使用してもよく、2種以上を組み合わせて使用してもよい。
また、本実施形態の処理剤における不揮発成分の含有割合を100質量部とすると、(A)平滑剤、(B)特定のオニウム塩、及び(C)非イオン界面活性剤の含有割合の合計は、50質量部以上であることが好ましく、75質量部以上であることがより好ましい。
次に、本発明の炭素繊維前駆体(以下、前駆体という)を具体化した第2実施形態について説明する。
付着処理工程における第1実施形態の処理剤の付着方法は公知の方法を適用できる。公知の付着方法としては、例えば、スプレー給油法、浸漬給油法、ローラー給油法、計量ポンプを用いたガイド給油法等が挙げられる。第1実施形態の処理剤を繊維に付着させる際の形態としては、例えば、有機溶媒溶液、水性液等が挙げられる。
製糸工程において、第1実施形態の処理剤を付着させるタイミング及び第1実施形態の処理剤を付着させる回数は特に制限されるものではない。例えば、紡糸工程前の原料繊維に付着させてもよいし、延伸工程後に付着させてもよい。延伸工程後に付着させるタイミングとしては、例えば、延伸工程の直後、延伸工程後の巻取り段階、耐炎化処理工程の直前が挙げられる。なお、第1実施形態の処理剤は、延伸工程前に一度付着させておくことが好ましく、延伸工程前に一度付着させておき、延伸工程直後に再度付着させることがより好ましい。
(1)第1実施形態の処理剤は、(A)平滑剤と、(B)特定のオニウム塩と、(C)非イオン界面活性剤とを含有する。第2実施形態の炭素繊維前駆体は、第1実施形態の処理剤が付着されている。
上記構成によれば、上記(1)の効果がより顕著に得られる。
上記構成によれば、処理剤を付着させた炭素繊維前駆体から得られた炭素繊維の強度が向上する。
上記構成によれば、上記(4)の効果に加えて、炭素繊維前駆体を製造する際の紡糸工程における集束性が向上するとともに、耐炎化処理工程における耐炎化繊維の集束性が更に向上する。
上記構成によれば、上記(3)の効果及び上記(4)の効果が得られやすい。
上記構成によれば、処理剤の安定性が向上する。
