METHOD FOR PRODUCING THERMOPLASTIC SYNTHETIC FIBER

摘要

PROBLEM TO BE SOLVED: To solve problems in a conventional art and to provide a uniform and efficient process for hot-drawing with a saved space in an accelerated one-step process. SOLUTION: This method for producing thermoplastic synthetic fibers is characterized by melt extruding a thermoplastic resin, subsequently irradiating the extruded fibers with laser beams and taking off the resultant fibers while drawing the fibers.
