Embodiment Construction
[0037] The invention is further illustrated by means of the following examples without being limited thereto.
[0038] Under the conditions listed in Table 1, use a relative viscosity of 2.04 (at 25°C with an Erbold viscometer (DIN51562) for 1 gram of polymer in 125 grams of 2,4,6-trichlorophenol and phenol mixture solution (TCF / F; 7:10 m / m)) of polyethylene terephthalate pellets were spun and cooled under the conditions listed in Table 1. The stretching speed was 6000 m / min. An additional slack of 0.5% was set and the winding speed was 5970 m / min.
