Abstract (en)

[origin: US5664307A] PCT No. PCT/EP94/01315 Sec. 371 Date Jul. 31, 1995 Sec. 102(e) Date Jul. 31, 1995 PCT Filed Apr. 26, 1994 PCT Pub. No. WO94/25653 PCT Pub. Date Nov. 10, 1994A draw process is described, in which yarns in particular of thermoplastic plastics are drawn by influencing their temperature, so as to improve the yarn properties. The process can be employed in a spin process or in a subsequent improvement step. In accordance with the invention, the temperature of the temperature modulating device is controlled as a function of a yarn tension signal, which is obtained within or downstream of the draw zone.
