摘　　要：以特性黏数(0.655±0.005)dL/g的半消光聚酯熔体为原料,分别采用先上油后拉伸、先拉伸后上油工艺路线生产50 dtex/24 f半消光涤纶全拉伸丝(FDY),对比了2种工艺路线下纤维的断裂伸长率、沸水收缩率、含油率及丝束张力对纤维染色性能的影响。结果表明:在断裂伸长率一致的情况下,采用先拉伸后上油工艺路线生产的FDY染色灰卡等级偏差小,最大偏差为偏深1.5级,比采用先上油后拉伸工艺路线的小;随着沸水收缩率增大,2种工艺路线生产的FDY染色均出现偏深;采用先拉伸后上油工艺路线时FDY含油率的变化对其染色性能没有影响,而采用先上油后拉伸工艺路线时,随着含油率上升,FDY染色灰卡等级偏差逐渐变大,最大偏差为偏深1.5级;采用先拉伸后上油工艺路线时,随着张力的增加,FDY染色偏浅,而采用先上油后拉伸工艺路线时张力对FDY染色性能几乎无影响。Using semi-dull polyester melt with an intrinsic viscosity of(0.655±0.005)dL/g as raw material,50 dtex/24 f semi-dull polyester fully drawn yarn(FDY)was produced through first oiling and then drawing process and first drawing and then oiling process.The effects of the elongation at break,boiling water shrinkage,oil content and bundle tension on the dyeing properties of the fiber were compared between two processing routes.The results showed that FDY produced by first drawing and then oiling process had a low dyeing gray card grade deviation with a maximum value of 1.5 degree darker,which was lower than that produced by first oiling and then drawing process at the same elongation at break;FDYs produced by these two process routes were both dyed darker as the boiling water shrinkage increased;the change in oil content of FDY had no effect on its dyeing properties while using first drawing and then oiling process,however,the dyeing gray card grade deviation of FDY gradually increased to a maximum of 1.5 degree darker with the increase of the oil content;and FDY produced by first drawing and then oiling process was dyed slightly lighter with the increase of tension,while the tension had almost no effect on the dyeing properties of FDY produced by first oiling and then drawing process.
