摘　　要：用热管纺丝拉伸一步法 ( TCS)生产 5 7dtex/36f涤纶超有光三角形 F DY ,探讨切片干燥、纺丝温度、速度、冷却条件、热管温度等对产品质量的影响。结果表明 :提高切片干燥程度 ,提高纺丝温度 3～ 8℃ ,上油率提高至 0 .92 % ,减缓冷却条件 ,降低热管温度至 176℃左右 ,纺丝速度为 460 0 m/m in时 ,所得产品的强度 3.9c N/dtex,伸度 30 .5 % ,沸水收缩率 5 .7% ,网络度 14个 /m,染色 M率大于等于85 %。TCS one\|step process was employed to produce 57 dtex/36f super bright triangle PET FDY. The effects of drying step, spinning temperature and velocity, quenching conditions, and thermal channel temperature on fiber quality were discussed. The experimental results showed that while enhancing chip drying, increasing spinning temperature by 3~8℃, and oil pick\|up up to 0.92%, mitigating quenching conditions, decreasing thermal channel temperature to about 176℃ and selecting spinning velocity of 4 600 m/min, the resulted fiber exhibited strength 3.9 cN/dtex, elongation 30.5%, boiling water shrinkage 57, network density of 14 per meter and M rate in order of 85% and above.
