Embodiment
[0023] Embodiment: take polyethylene as raw material to illustrate
[0024] (1) Raw material: polyethylene;
[0025] (2) Screening and conveying of raw materials: Vibration is used to screen materials, and the vibration frequency of the vibrating screen is controlled at 400 times / min;
[0026] (3) Drying: 80°C rotary dryer to remove moisture;
[0027] (4) Melting and spinning: melted and extruded by a new extruder, the temperature of the screw zone is controlled at: 158°C in the first zone, 165°C in the second zone, 172°C in the third zone, 180°C in the fourth zone, 179°C in the fifth zone, and 179°C in the sixth zone 178°C, the material is continuously melted, homogenized, and plasticized in the extruder, and the melt is filtered and then enters the spinning machine to form melt filaments under the action of the metering pump and spinning components;
[0028] (5) Ring blowing cooling: cooling the filaments, the wind temperature is 18°C, the relative humidity is 70%, the win...
