Example Embodiment
[0040] Example 1
[0041] 1) Add 0.24kg of activated graphene, 0.12kg of carboxylated carbon nanotubes, 10kg of polypropylene chips, and 2kg of high-density polyethylene chips into a high-speed mixer with a rotation speed of 600rpm for 30 minutes. Mixed and extruded in the screw extruder, the extruded material is quenched in a water bath at room temperature, and then pulled into the pelletizer for slices;
[0042] 2) Spread the composite pellets prepared in step 1 on a stainless steel tray, place them in an oven at 85°C for 10 hours, and spin the pellets in a vertical melt spinning machine to obtain spun silk;
[0043] 3) The nascent silk is dried, oiled, drafted by a draft roller, and wound and winded to obtain a composite fiber. During spinning, the spinning machine parameters are set as follows: the main engine speed is 25rpm, the temperature of the feeding section, the melting section and the head section are respectively controlled to 220℃, 240℃, 230℃, and the rotation speed ...

[0048] Example 3
[0049] 1) After manually mixing 0.8kg of activated graphene, 0.4kg of carboxylated carbon nanotubes, 9kg of polypropylene chips, and 3kg of high-density polyethylene chips, add them to a high-speed mixer at 1000rpm and mix for 15 minutes. Add to the twin-screw extruder at a uniform speed for mixing and extruding. The extruded material is quenched in a water bath at room temperature and pulled into the pelletizer for slices;
[0050] 2) Spread the composite pellets prepared in step 1 on a stainless steel tray and place them in an oven at 105°C for drying for 8 hours, and spin the pellets in a vertical melt spinning machine to obtain spun silk;
[0051] 3) The nascent silk is dried, oiled, drafted by a draft roller, and wound and winded to obtain a composite fiber. During spinning, the spinning machine parameters are set as follows: the main engine speed is 20rpm, the temperature of the feeding section, the melting section and the head section are respectively con...
