| Abstract: | The ultraviolet resistant masterbatch with water content lower than 80 μg/g was proportionally (7%) fed into screw extruder by CAD dosing feeder and was melt\|spun with PET chip. Coordinated with other processing conditions, the spinning velocity should be selected as 2 200 m/min and manifold temperature 278 5℃. The resulting ultraviolet resistant fiber exhibits tenacity in the range of 1 7~1 8 cN/dtex, elongation 170%~190%, ultraviolet screen degree of 98% and far\|infrared emissivity of 82%. |
