Abstract

　エマルジョン紡糸法のようにマトリックス材を用いることなくポリテトラフルオロエチレン（ＰＴＦＥ）繊維、特にＰＴＦＥ長繊維を製造できるとともに、スリットヤーン法を含む従来の製造方法よりも生産性に優れ、得られる繊維の機械的特性ならびに径の自由度を向上できるＰＴＦＥ繊維の製造方法を提供する。紐状のＰＴＦＥ含有固形物（第１の固形物）を、ＰＴＦＥの融点以上の温度において引き抜き加工することにより、上記第１の固形物を細径化する方法とする。第１の固形物は、例えば、水および界面活性剤を内包する紐状のＰＴＦＥ含有固形物（第２の固形物）から、当該固形物に含まれる水の量を低減させて得ることができる。
