| Abstract: | Triangle and trilobal polyester fully drawn yarns(FDY) of 55 dtex/36 f were prepared by direct melt-spinning process.The production process was discussed.The results showed that the spinning process was smooth and the fiber had high quality with clear cross section shape as the process conditions were as followed: triangle and trilobal spinneret,nipple oiling,spinning temperature 291 ℃,cross air blow speed 0.40-0.45 m/s,spinning speed 3 200-4 200 m/min,the first roll temperature 69-90 ℃,the second roll temperature 126 ℃.The triangle and trilobal polyester FDY had the breaking strength of 4.21 and 4.08 cN/dtex,elongation at break of 31.74% and 30.44%,yarn irregularity of 0.92% and 0.86%,and boiling water shrinkage of 7.59% and 7.35%,respectively. |
