PROCESS FOR SHAPING POLYMER MIXTURES INTO FILAMENTS |
摘要 |
A process is disclosed for producing pre-oriented filaments from polyester-based polymer mixtures by spinning polymer mixtures at a drawing-off speed v of at least 2500 m/min, a second amorphous, thermoplastically deformable copolymer with a glass transition temperature of more than 100 DEG C being added to the polyester. The process is characterised in that the ratio between the viscosity of the molten copolymer and the viscosity of the molten polyester equals 1:1 to 10:1 (measurement parameters as described), that the amount of copolymer added to the polyesters equals at least 0.05 wt %, that the maximum amount M of copolymer added to the polyester is dependent on the drawing-off speed v and that the value of M is M = [1/1600 . v(m/min) - 0,8]. |
