摘　　要：对涤纶FDY生产线进行双头纺改造,由六头纺改为十二头纺；将喷丝孔由圆形均匀分布改为中间留有缝隙的对称两部分,丝路上导丝器、网络喷嘴相应增加1倍,每个卷绕头卷绕12个丝筒。改造后调整丝路,控制侧吹风速度0．6m/s,全部使用60目海砂,第一、二热辊温度较改造前提高5℃,拉伸倍数为2．8,纺丝顺利,生产稳定。生产68dtex/24f涤纶FDY产品的一等品率为90%,吨丝生产加工成本降低了43%。The technological innovation in double-spinning process for polyester FDY was conducted. The original 6-end spinning was transformed into 12-end spinning. The arrangement of spinneret holes was transformed from the uniform circular distribution into two symmetric parts separated with a gap. The number of yarn guides and interlacing jets was doubled along with the yarn path. Each winding end was capable of winding 12 bobbins. After the technological innovation, the first-rate percentage of 68 dtex/24 f PET FDY was 90% and the production cost was decreased by 43% with smooth spinning and steady production under the conditions of cross air speed 0.6 m/s, 60 mesh sea sand,the temperatures of the first and second heat rolls 5℃ higher than those before innovation, draw ratio 2.8.
