    • A method is described of drawing a pre-oriented multifilament yarn (POY yarn). Hereby the multifilament yarn is fed from a delivery godet, around which it is wrapped, at a first velocity into a main drawing zone and removed from the main drawing zone at a second velocity by a drawing-off godet around which it is wrapped. The drawing in the main drawing zone takes place between the delivery godet and the drawing-off godet whereby the drawing-off godet is heated to a temperature of between 160.degree. C. and 240.degree. C. The first and the second velocities are so adjusted with respect to each other that the second velocity is 70% to 180% greater than the first velocity.
    • 描述了一种绘制预定向复丝纱线(POY纱线)的方法。 因此,复丝纱线以其第一速度被从包裹的输送导丝辊供给到主拉伸区域中,并通过被包裹的牵引导丝辊以第二速度从主拉伸区域移除。 在主要拉伸区域中的拉伸是在输送导丝辊和牵引导丝辊之间进行的,由此将导丝辊加热到160℃和240℃之间的温度。第一和第二速度被如此调节 相对于彼此,第二速度比第一速度大70%至180%。
