Embodiment 1
[0025] A processing technology for producing special-shaped fibers for oil-absorbing felts, using modified polypropylene as a base material for processing, including the following steps:
[0026] (1) Wash, dry, crush, and sieve the loofah scoop to obtain loofah scoop powder with a particle size of 50 meshes, then completely immerse the loofah scoop powder in the treatment solution for ultrasonic treatment, and the ultrasonic temperature is 40 o C. Ultrasonic time is 40 minutes. Use clear water to clean the loofah scoop powder after ultrasonic treatment, and finally place it in a ventilated place to dry until the moisture content reaches 5%. The processed loofah scoop powder is ready for use;
[0027] (2) Add certain parts by mass of polypropylene resin, loofah powder, filler, compatibilizer, light stabilizer, flame retardant, and surfactant into a high-speed mixer and mix evenly to obtain a mixture;
[0028] (3) Add the mixture obtained in step (2) into a twin-screw extruder f...
Embodiment 2
[0038] A processing technology for producing special-shaped fibers for oil-absorbing felts, using modified polypropylene as a base material for processing, including the following steps:
[0039](1) Wash, dry, crush, and sieve the loofah scoop to obtain loofah scoop powder with a particle size of 80 mesh, and then completely immerse the loofah scoop powder in the treatment solution for ultrasonic treatment. The ultrasonic temperature is 35 o C. Ultrasonic time is 50 minutes. Use clear water to clean the loofah scoop powder after ultrasonic treatment, and finally place it in a ventilated place to dry until the moisture content reaches 5.5%. The processed loofah scoop powder is ready for use;
[0040] (2) Add certain parts by mass of polypropylene resin, loofah powder, filler, compatibilizer, light stabilizer, flame retardant, and surfactant into a high-speed mixer and mix evenly to obtain a mixture;
[0041] (3) Add the mixture obtained in step (2) into a twin-screw extruder fo...
Embodiment 3
[0051] A processing technology for producing special-shaped fibers for oil-absorbing felts, using modified polypropylene as a base material for processing, including the following steps:
[0052] (1) Clean, dry, crush, and sieve the loofah scoop to obtain loofah scoop powder with a particle size of 100 mesh, and then completely immerse the loofah scoop powder in the treatment solution for ultrasonic treatment. The ultrasonic temperature is 38 o C. Ultrasonic time is 55 minutes. Use clear water to clean the loofah scoop powder after ultrasonic treatment, and finally place it in a ventilated place to dry until the moisture content reaches 4%. The processed loofah scoop powder is ready for use;
[0053] (2) Add certain parts by mass of polypropylene resin, loofah powder, filler, compatibilizer, light stabilizer, flame retardant, and surfactant into a high-speed mixer and mix evenly to obtain a mixture;
[0054] (3) Add the mixture obtained in step (2) into a twin-screw extruder f...
