摘　　要：在熔体直纺环吹线上,通过优化预取向丝(POY)伸度指标、上油率指标、假捻牵伸比、假捻器组合、D/Y、第一热箱温度等工艺条件,同时对染色M率进行管控,研究了133 dtex/144 f涤纶低弹丝的生产工艺。试验表明:当POY伸度指标控制在129%~136%,POY含油率控制在0.4%~0.55%,假捻牵伸比控制在1.67~1.69,假捻器使用1-5-1盘片组合,D/Y控制在1.55~1.65时,适当降低第一热箱温度,并对染色指标进行管控,可加工得到较优质的低弹丝产品。On the melt direct spinning ring blowing line, the production processes of 133 dtex/144 f polyester yarn low-elastic were studied by optimizing the pre-oriented yarn(POY) elongation index and oiling rate, as well as the drafting ratio of false twist, combination of false twister, D/Y and the temperature of Hhot box, and controlling the dyeing M rate. The tests show that when POY elongation index is 129%~136%,POY oil rate is controlled 0.40%~0.55%, false twist drafting ratio is 1.67~1.69, false twister uses 1-5-1 disc combination, D/Y is controlled 1.55%~1.65%, the temperature of Hhot box is appropriately reduced,and the dyeing index is controlled, high quality low-elastic yarn products are obtained.
