Example Embodiment
[0035] Example 1
[0036] Produce 222.2dtex / 24F PET DTY filament.
[0037] Raw material: PET, intrinsic viscosity (0.675±0.015)dL / g, melting point 240~255℃
[0038] Spinneret hole design such as figure 1 As shown in (a-1), the orifice parameters are d = 0.05mm, s = 0.10mm, h = 0.15mm, g = 0.05, L = 1.05mm, p = 0.02mm, W = 0.10mm, 2×6 (6 grooves on each side, the same below) groove.
[0039] Use Foume110L vacuum drum dryer to dry the PET slices (process conditions: temperature 145℃, time 48h; moisture content after drying 50ppm) to obtain dry slices with better uniformity, and send them to the screw extrusion model of ABEΦ25×2 The spinning machine melts and extrudes, enters the spinning assembly through the melt pipe, and is ejected from the spinneret, and then is cooled by side blowing, oiled, wound, and doffed to obtain POY yarn. Finally, it passes through the first heat box to deform and false The twister, the second heat box are shaped, and the oil is wound. The specific spinnin...

[0040] Example 2
[0041] Produce 111.1dtex / 24F polyester PET DTY filament.
[0042] Raw material: PET, intrinsic viscosity 0.496±0.015)dL / g, melting point 240~251℃.
[0043] Spinning hole such as figure 1 As shown in (b-1), the spinneret hole parameters are d=0.05mm, s=0.10m, h=0.15mm, g=0.05, r=0.05, L=0.60mm, W=0.10mm, 2×3 grooves groove.
[0044] Use Foume110L vacuum drum dryer to dry the PET slices (process conditions: temperature 145℃, time 48h; slice moisture content after drying 50ppm) to obtain dry slices with good uniformity, and send them to the screw extrusion model ABEΦ25×2 It is melted and extruded from the spinning machine, enters the spinning assembly through the melt pipe, and is ejected from the spinneret, and then is cooled by side blowing, oiling, winding, and doffing to obtain POY yarn. Finally, it is deformed by the first heat box. The false twister, the second heat box are shaped, and the winding is oiled. The winding speed is 800m / min. Other spinning process...

[0045] Example 3
[0046] The polyester PTT DTY filament of 111.1 dtex / 36F was produced.
[0047] Raw material: PTT, intrinsic viscosity (1498±0.015) dL / g, melting point 228~233℃.
[0048] Spinning hole such as figure 2 As shown in (a-1), the spinneret hole parameters were d=0.08mm, s=0.10mm, h=0.12mm, g=0.05m, L=0.64mm, p=0.02mm, W=0.10mm, 2× 3 Groove.
[0049] Use Foume110L vacuum drum dryer to dry the PET slices (process conditions: temperature 120℃, time 48h; slice moisture content after drying 30ppm) to obtain uniformly dried slices, and send them to the screw extrusion model ABEΦ25×2 It is melted and extruded from the spinning machine, enters the spinning assembly through the melt pipe and is ejected from the spinneret, and then is cooled by side blowing, oiling, winding, and doffing to obtain POY yarn. Finally, it is deformed by the first heat box. False twister, second heat box shaping, oiling and winding, the specific spinning process parameters are shown in Table 2.
