ABSTRACT:
The objective of the present invention is to enable a microfilament that is a nanofilament to be manufactured continuously and consistently from all thermoplastic polymers without requiring a specialized high precision•high performance apparatus and also to present the nanofilament manufactured as described. The present invention comprises a microfilament in a nanofilament region and the manufacturing means thereof wherein a original filament transferred using a filament transfer means is supplied to an orifice under pressure P1and is heated and drawn using an infrared light beam directly under the orifice under pressure P2(P1>P2).
