| abstract | PROBLEM TO BE SOLVED: To prevent oxidative deterioration of deposits deposited around a discharge hole group of a spinneret and to quickly remove a stagnant air flow containing low-boiling substances from a polymer discharge surface of the spinneret. hand, These suppress the accumulation around the ejection hole group. And by providing such a means, not only the production efficiency is improved, but also a spinneret capable of improving the quality of the nonwoven fabric directly or indirectly manufactured from the spun synthetic fiber group, and using the spinneret. An object of the present invention is to provide a nonwoven fabric manufacturing apparatus. SOLUTION: In order to flow an inert gas through a group of thermoplastic polymer discharge holes (15, 15 ') drilled at high density in a rectangular area in order to spin a thermoplastic synthetic fiber group (Y). A gas flow path group including an inert gas introduction flow path (12, 12 ') and a distribution flow path (13, 13') provided between the discharge holes (15, 15 ') group, A melt spinneret (1a, 1) which includes a gas blowout hole (14, 14 ') for blowing out the inert gas from the gas flow path group to the polymer discharge surface. 1b). |
