| Abstract: | A flat polyester FDY of 130 dtex/36 f was prepared from polyester melt with the intrinsic viscosity of(0.645±0.010)dL/g via direct spinning process.The results showed that the polyester FDY with the full-package rate of 80.9%,breaking strength 3.31 cN/dtex,elongation at break 30.O1%can be produced using a 36 f flat spinneret by appropriately increasingthe initial pressure of the spinning pack and controlling the spinning temperature 287 ℃,quench air speed 0.5 m/s,rotating rate of oiling roller 40 r/rain and the first and second hot roller temperature 92 ℃ and 132 ℃,respectively. |
