본　발명은　폭보다　큰　두께를　갖는　수직　단면을　갖는,　80　중량%　이상의　플루오로중합체를　함유하는　신장된　필라멘트의　제조　방법에　관한　것이다. 미가공　필라멘트는　70 ℃　내지　비캣　온도의　온도에서　3　이상의　신장　인자에　의해　신장되며,　여기서 필라멘트를　전체　인장　하중　하에　신장시킨　후에　50 ℃　이하로　냉각시키고,　퍼플루오린화　중합체를　함유하지　않는다. The present invention is directed to stretched filaments based on fluoropolymers, where the filaments were stretched at a temperature between 70° C. and the Vicat temperature and where the filaments are cooled under full tensile load to room temperature.
