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 P1 and is heated and drawn using an infrared light beam directly under the orifice under pressure P2 (P1>P2).
Claims24
A method for manufacturing microfilament, comprising the steps of supplying an original filament to an orifice under P1 pressure using a filament transfer means, then heating the filament P2 pressure (P1>P2) using an infrared light beam and drawing the filament, wherein the pressure difference between P1 and P2 before and after said orifice is P1≧2P2.
(canceled)
A manufacturing apparatus for microfilament comprising;
- an original filament supply chamber under pressure P1 containing a means to transfer the original filament,
- an orifice positioned in said original filament supply chamber through which said original filament passes,
- a drawing chamber, connected to said original filament supply chamber through said orifice, which said original filament that passed through said orifice is heated using an infrared light beam and drawn, and drawing chamber being under pressure P2 wherein the pressure difference between P1 and P2 is P1≧2P2,
- and an infrared ray irradiation device that radiates said infrared light beam.
