Description
このような二つの技術でナノ繊維よりなるナノ繊維ウェブを製造できることが分かる。
本発明は前述した問題点を解決するために案出されたもので、その目的は熱可塑性樹脂及び熱硬化性樹脂の両方を使用でき、溶液加熱が必須的ではなく、絶縁方法の具現が容易なナノ繊維の製造方法を提供するところにある。
本発明の他の目的は前述した製造方法を具現するためのナノ繊維の製造装置を提供するところにある。
前述した他の目的を達成するための本発明に係るナノ繊維の製造装置は、ポリマー溶液を製造するための貯蔵槽と、該貯蔵槽から搬送されたポリマー溶液が吐出される出糸ノズルと、該出糸ノズルの下部に圧縮空気が噴射されるエアノズルと、前記出糸ノズルに高電圧を印加する電圧付与手段と、前記出糸ノズルから吐出された出糸繊維をウェブ状に捕集するための接地されたコレクターとよりなる。
貯蔵槽100はポリマー溶液製造のためのもので、ポリマーと溶媒の配合を通してポリマー溶液を製造する。本発明において使用可能なポリマーは熱可塑性樹脂だけに制限されず、熱硬化性樹脂などのほとんどの合成樹脂が使用できる。
前記出糸口金102に印加される電圧は1kV〜300kVの範囲が望ましく、10〜100kVが特に望ましい。前記ポリマー溶液の吐出圧力は0.01〜200kg/cm2範囲で使用でき、特に0.1〜20kg/cm2の範囲が望ましいが、これより高吐出量を実現できて大量生産に適している。静電出糸法と比較して0.1〜5cc/min・holeの高吐出量でポリマー溶液を吐き出せる。
さらに、エレクトロ−ブローン出糸工程に使用される装置構成において、出糸口金の絶縁が容易であり、吸気を通して溶剤回収が可能である。
Claims (4)
