摘要(Abstract)：
在阳离子染料可染聚酯熔体直纺预取向丝(POY)生产线上,探讨了生产紧厚绒织物专用纤维的生产工艺。结果表明:在阳离子染料可染聚酯熔体直纺POY生产线上进行技术和设备创新,可以生产出染色性能优异,布面绒毛厚密均匀,手感光滑细腻的紧厚绒织物专用纤维。经过系列的工艺摸索与优化,最终选择纺丝速度2700 m/min,风压50～60 Pa,箱体温度288℃,冷却风温度23℃,卷绕张力74～84 cN,生产出的780 dtex/144 f紧厚绒织物专用纤维的各项指标优良。
The manufacturing technology of cationic dyeable polyester pre-oriented yarn(POY) for tight-heavy fleece goods on melt-direct spinning line is discussed.The result indicates that the innovation of technology and equipment on the line is enabled to produce the tight-heavy fleece fiber which has outstanding dyeing behavior,even coverage of villus as well as soft and smooth touching on the cloth surface.After rounds of exploration and optimization to the manufacturing process,the parameters are selected with spinning speed at 2 700 m/min,wind pressure at 50～60 Pa,box temperature at 288 ℃,cool wind temperature at 23 ℃,winding tension at 74 ～84 cN,thus the line could make 780 dtex/144 f exclusive fiber with great performance in each index,for tight-heavy fleece goods.
