| titleOfInvention | Melt spinneret for ultrafine fibers and melt spinning method |
| abstract | (57) [Summary] [PROBLEMS] A spinning speed of 2 without passing through a conjugate fiber. At 000 m / min or more, the single fiber fineness is 0.2 to 0.6. a melt-spinning method capable of obtaining a low-oriented undrawn yarn having dtex and having a number of filaments of 100 or more without causing filament breakage and maintaining a stable spinning condition; and the melt-spinning method. The present invention provides a melt spinneret that has been made possible. SOLUTION: The single fiber fineness is 0.2 to 0.6 dtex, and A melt spinning die (1) in which a group of discharge holes (11) for melt spinning thermoplastic ultrafine fibers having a number of filaments of 100 or more at 2000 m / min or more is provided; 1) a polymer discharge surface (12) of the die (1) in which the group is opened, Melting of ultrafine fibers having an intersection (13) formed between each side wall surface of the group of opened discharge holes (11) and having an edge processed to have a chamfer and / or radius of 1.0 to 5.0 μm. Spinneret Using the melt spinning die (1) and the melt spinneret (1), a method for melt spinning ultrafine fibers to obtain an ultrafine polyester fiber having a birefringence (ΔN) of 0.04 to 0.08 after winding. It is. |
