摘　　要：对聚酯二甘醇含量波动对直纺长丝生产及产品质量的影响进行了分析讨论。初步认为就FDY而言,当聚酯 二甘醇波动范围控制在0.14％左右时,绝大部份直纺FDY产品的染色性能不受影响;当聚酯二甘醇波动范围控制在0. 25％左右时,直纺FDY常规品种的染色性能不受影响,但差别化品种(如多孔细旦的FDY 88 dtex71 f等品种)会存在色差。The influence of the fluctuation of DEG on direct spinning continuous filament has been concluded by date collection, analyzing and discussion when event once took place in big polyester unit, and some quantitative conclusion has been drawn out. To FDY, if the variation of DEG in polyester is controlled within 0.14%, the dying quality of FDY will not be affected . if the variation of DEG in polyester is controlled within 0.25% . the dying quality of normal FDY will not be affected, but the multi and fine denier filament (such as FDY 88 dtex/71 f) will be affected.
