Embodiment 1
[0012] figure 1 and figure 2 , adjust the distance between the nozzle (11) and the collection cylinder (3) to be 17 cm, and put 30 grams of polypropylene into the feeding chamber (9). Turn on the power supply of the heating rod (6) and the electric heating plate (4), when the temperature of the feeding chamber (9) and the spray chamber (5) both reach 230°C, keep the heat for 10 minutes, then open the valve (10), and the polypropylene The melt flows into the spray chamber (5), and a voltage of 20KV is applied between the nozzle (11) and the collecting cylinder (3), and the speed of the motor (13) is gradually adjusted from 0 to 13000 rpm, and the high-speed rotating The spinning nozzle (5) spins the melt and falls on the collecting cylinder (3). After the spinning is finished, the power is turned off, and the spun filaments are collected. After measurement, the fiber diameter is 200-600 nanometers.
