Beschreibung
Zusammenfassung:	A method for producing a polypropylene thread (10) using a drawing system (1) is described, the drawing system (1) comprising at least two drawing towers (2, 7) associated with at least one heating element (4), wherein the method for producing a polypropylene thread comprises the steps of: heating the polypropylene thread (10) prior to introducing it into the heating element (4), introducing the polypropylene thread (10) into the heating element (4), and cooling the polypropylene thread (10). 描述了一种使用拉伸系统(1)生产聚丙烯纱线(10)的方法，所述拉伸系统(1)包括与至少一个加热元件(4)相关的至少两个拉伸塔(2、7)，其中所述生产聚丙烯纱线的方法包括以下步骤：在将聚丙烯纱线(10)引入加热元件(4)中之前加热所述聚丙烯纱线(10)，将所述聚丙烯纱线(10)引入加热元件(4)中，和冷却所述聚丙烯纱线(10)。
