摘要： A first stream of a polyester melt is divided into a second and a third polyester stream, the flow rate of the first stream being 100 to 2000 kg/h and the flow rate of the second polyester stream being 5 to 300 kg/h. 0.2 to 100 kg/h of a molten additive polymer is metered to the second polyester stream, and the additive polymer together with the second polyester stream is passed through a first mixing line. There is obtained a first polymer mixture whose content of additive polymer is 3 to 50 wt-%. The first polymer mixture is introduced into the third polyester stream, the first mixture together with the third polyester stream being passed through a second mixing line and forming a second polymer mixture. The second polymer mixture is extruded to obtain filaments, the filaments are cooled and combined to threads, the threads are unwound with a speed of at least 1000 m/min. The threads are processed to obtain either continuous threads or staple fibers.
