Process for processing polymer mixtures to filaments
Process for the production of preorientated filaments from polyester-based polymer mixtures by spinning the polymer mixtures with a draw-off speed v of at least 2500 m/min, a second amorphous, thermoplastically processable copolymer having a glass transition temperature of more than 100 DEG C being...

Summary: | Process for the production of preorientated filaments from polyester-based polymer mixtures by spinning the polymer mixtures with a draw-off speed v of at least 2500 m/min, a second amorphous, thermoplastically processable copolymer having a glass transition temperature of more than 100 DEG C being added to the polyester, which is characterized in that the radio of the melt viscosity of the copolymer to the melt viscosity of the polyester is 1:1 to 10:1 (measurement parameters as described), in that the amount of copolymer added to the polyester is at least 0.05 wt.%, in that the maximum amount M of the copolymer added to the polyester depends on the draw-off speed v, and in that . |
