example 1

[0106] Thermoplastic polyurethane resin is melt-spun at a melting temperature of 220°C from a spinning machine having 24 holes (hole diameter φ1.0) formed in a line in a line (SUS630: W360×T80×H20mm) The head was spun and cooled by rectified unidirectional cooling air blown from perpendicular to the direction of the row at a velocity of 0.3 m / min. Then, the filament was oiled by roller oiling, and the formed molten spandex filament (22 dtex, one filament) was wound up. The vibration of the filaments during winding in the cooling zone, the properties of the obtained filaments, the unevenness of the filaments and the grade of the bare knitted fabric were evaluated.

example 2

[0108] Thermoplastic polyurethane resin is melt-spun at a melting temperature of 220°C, from a spinning machine having 24 holes (hole diameter φ1.0) formed in a line in a line (SUS630: W360×T80×H20mm) The head was spun and cooled by rectified unidirectional cooling air blown from perpendicular to the direction of the row at a velocity of 0.3 m / min. Then, the filament was oiled by roller oiling, and the formed fused spandex filament (44 dtex, 2 filaments) was wound up. Perform an evaluation similar to Example 1.

example 3

[0110] Thermoplastic polyurethane resin is melt-spun at a melting temperature of 220°C from a spinning machine having 24 holes (hole diameter φ1.0) formed in a line in a line (SUS630: W360×T80×H20mm) The head was spun and cooled by rectified unidirectional cooling air blown from perpendicular to the direction of the row at a velocity of 0.3 m / min. Then, the filament was oiled by roller oiling, and the formed fused spandex filament (66 dtex, 3 filaments) was wound. Perform an evaluation similar to Example 1.

Abstract

The present invention relates to a spinning head for synthetic fibers, an oiling device, a spinning device and a manufacturing method thereof. The spinning head (1) comprises a single row of spinning holes (2). The filaments discharged from the spinning hole (2) of the spinneret (1) avoid twisting and are wound up to the take-up roll (12) by means of an oiling device (8) and guide devices (9, 10). In the spinning head (20), a groove (24) may be formed to extend in a radial direction and have its center located in the spinning hole (23). A molten polymer filtered by the filter medium (22) can enter the spinning hole (23) through the slot (24). The oiling device (31) may include an oiling device (8) and a guide element (9), and the cooperation of the two elements prevents incomplete oiling.

Description

technical field [0001] The present invention relates to a spinneret / spinneret, an oiling device, a manufacturing device and a manufacturing method for synthetic fibers. The present invention will be described in detail below. [0002] First, the present invention relates to a spinneret for spinning a plurality of filaments / single fibers and then winding them while dividing and solidifying the filaments, and to a synthetic fiber using the spinneret Fiber manufacturing method. More specifically, the present invention relates to a spinneret that reduces variations in physical properties among a plurality of filaments. [0003] Secondly, the present invention relates to a spinning head suitable for producing polyurethane fibers, polyester fibers, polyamide fibers, polyolefin fibers, etc., and more particularly, to a spinning head capable of prolonging the service life of filter media and stably discharging polymerized spinning head. [0004] Third, the present invention relate...
