    • The present invention pertains to a process for the production of a polyester multifilament yarn having at least 90 mol % ethylene terephthalate with a single filament titer of 1 to 20 dtex, using a central quenching system, characterized in that the method has the following steps: Extrusion of a polyethylene terephthalate polymer melt through a spinneret that has a number of capillaries between 150 and 1500, adjusting a spacer length between 5 and 150 mm, cooling of the obtained threads by means of a constant blown-air speed profile defined in the thread transit direction in that it initially rises very quickly in the region facing the spinneret, then reaches a maximum and subsequently drops off initially very quickly, then more slowly, with the average blown air speed in the vicinity of the threads being between 0.15 and 1.5 m/sec, in such a manner that the undrawn yarn produced from the process has a birefringence of between 0.050 and 0.130, and the coefficient of variation in tenacity at break between the undrawn, single filaments of a yarn amounting to a maximum of 6% with the coefficient of variation in the elongation at break amounting to a maximum of 8%, whereby finally the undrawn yarn is further processed into a finished yarn.
    • 本发明涉及使用中心淬火系统制造具有单丝滴度为1〜20分特的至少90摩尔%的对苯二甲酸乙二醇酯的聚酯复丝纱线的方法,其特征在于,该方法具有以下步骤: 将聚对苯二甲酸乙二醇酯聚合物熔体挤出通过喷丝头,其喷丝头具有150至1500之间的毛细管,调整间距长度在5至150mm之间,通过在螺纹中限定的恒定的吹气速度轮廓来冷却所获得的螺纹 因为它最初在面对喷丝头的区域上迅速上升,然后达到最大值,随后最初非常快地下降,然后更慢,螺纹附近的平均吹风速度在0.15和1.5米之间 /秒,使得由该方法生产的未拉伸纱线的双折射率在0.050和0.130之间,并且榫钉的变异系数 在未拉伸的纱线之间断裂,断丝伸长率的变化系数最大为6%,最后将未拉伸丝进一步加工成成纱。
