Description
用語「電気ブローイング」および「電気ブロー紡糸」は本明細書では同義的に、推進ガス流れがコレクターの方へ一般に向けられ、そのガス流れ中へポリマー流れが紡糸ノズルから注入され、それによってコレクター上に集められる繊維ウェブを形成する繊維ウェブの形成方法であって、電圧差が紡糸ノズルと電極との間に維持され、そして該電圧差が紡糸ノズルからポリマーが出るときにそれに電荷を与えるのに十分な強度のものである方法を意味する。
シグマ−アルドリッチ、ミズーリ州セントルイス(Sigma−Aldrich,St Louis,MO)から入手可能な、ポリ(エチレンオキシド)(PEO)、粘度平均分子量(Mv)約300,000を脱イオン水に溶解させて10重量%PEO溶液を調製する。溶液電気伝導率は、VWRサイエンティフィック・プロダクツ(VWRインターナショナル社、ペンシルバニア州ウェスト・チェスター)(VWR Scientific Products(VWR International,Inc.,West Chester,PA))から入手可能なVWRデジタル導電率計を用いて47マイクロジーメンス/cmであると測定される。溶液を、同心の推進空気ジェット中、26ゲージの尖っていない注射針を含んでなる単一オリフィス電気ブローイング装置で紡糸する。針先端は、紡糸パック本体の導電性面の下方に2.5mm突き出ている。高電圧を紡糸パック本体および紡糸オリフィスにかける。PEO溶液を、電流計を通して電気的に接地されているリング形状電極を通して導く。好適なプロセス条件は下の表にある。
より小さい内径の電極で、電極をダイ先端のより近くに置き、そしてより低い電圧を紡糸口金にかけたことを除いて実施例1の手順に従う。好適なプロセス条件を下の表にリストする。約100〜約700ナノメートルの範囲の繊維径を有するナノファイバーを集める。
紡糸口金に関してわずかにより高い電圧を使った以外は実施例2の手順を繰り返す。好適なプロセス条件を下の表にリストする。約100〜約700ナノメートルの範囲の繊維径を有するナノファイバーを集める。
PCT公開国際公開第03/080905A号パンフレットに従った手順に従った。本手順は、電極が全く存在しない0.1メートル紡糸パックを含んだ。−60kVの高電圧を紡糸口金にかけ、コレクターを接地した。
本発明の好適な実施態様は次のとおりである。
1. 電気的に帯電したポリマー流れを、紡糸口金の電気的に帯電した紡糸ノズルから、前記紡糸ノズルに隣接して配置されたガスノズルから放出されるガス流れ中へ出す工程と、帯電したポリマー流れから形成されたナノファイバーを繊維ウェブとしてコレクター上に集める工程とを含んでなる繊維ウェブを形成するための電気ブローイング方法であって、
電気的に帯電したポリマー流れを実質的に接地されている電極の側に通すこと、前記電極が前記紡糸口金と前記コレクターとの間に配置されていることを特徴とする方法。
2. ポリマー流れがポリマー溶液の流れである上記1に記載の方法。
3. ポリマー流れが溶融ポリマーの流れである上記1に記載の方法。
4. ポリマー流れが導電性である上記1に記載の方法。
5. コレクターが実質的に接地されている上記1に記載の方法。
6. 紡糸口金と電極との間の電圧差が約1〜約100kVの範囲にある上記1に記載の方法。
7. 紡糸口金と電極との間の電圧差が約2〜約50kVの範囲にある上記6に記載の方法。
8. ポリマー流れが負に帯電している上記1に記載の方法。
9. ポリマー流れが正に帯電している上記1に記載の方法。
10. ポリマー流れが約0.1cc/分〜約15cc/分の範囲の穴当たり処理量で紡糸ノズルを出る上記1に記載の方法。
11. 電極が紡糸ノズルの出口から約0.01cm〜約100cmの距離に配置される上記1に記載の方法。
