摘　　要：从侧吹风速、上油率、热辊温度、拉伸倍率等纺丝工艺条件对166.6dtex/35f涤纶FDY染色均匀性进行探讨,并对其生产工艺进行理论分析和实践检验.结果表明：166.6dtex/35f品种的侧吹风速宜选择在0.6～0.85m/s,上油率控制在0.65％～0.8％,第一热辊温度控制在93℃左右,第二热辊温度选择137℃、拉伸倍率在3.5左右时,能够保证产品的染色均匀性和生产稳定性.This paper discusses FDY dyeing uniformity of 166.6dtex/35f polyester FDY from technological conditions of the side blowing speed, the oil content, the hot roller temperature, the drawing rate etc. The results show that the dyeing uniformity and the production stability of the product can be ensured through choosing the best technological conditions as follows： the side blowing speed： 0. 6-0. 85m/s, the oil content： 0. 65%-0. 8%, temperature of the first hot roller： about 93℃, temperature of the second hot roller： about 137℃, the drawing rate： 3. 5 etc.
