1. If the cloth is still not soft at the recommended relatively high temperature, there may be a problem with temperature sensing or temperature control, so directly continue to increase the temperature until the cloth is in a soft state;

2. If the wind pressure is below 0.2Mpa and the die temperature is near or below 210°C, there will be a phenomenon of flying. The melt finger of the meltblown PP material may be abnormal, or the temperature induction may be abnormal, the wind pressure display is abnormal, or the air duct tuyere size If the angle is abnormal, you need to contact the equipment manufacturer or raw material manufacturer to eliminate the abnormality;

3. It is recommended to use low temperature materials for large equipment and medium and high temperature materials for small equipment;

4. Generally, when the temperature is very high, the cloth is still not soft, or it starts to become brittle, and then the temperature is further increased, and the cloth starts to become soft. Generally speaking, there is a problem with the equipment itself. It is recommended to contact the equipment manufacturer, or the material is of serious quality problem;

5. The addition of electret masterbatch generally needs to be matched by adjusting appropriate process parameters. Different electret masterbatches have different corresponding process parameters, and can be adjusted to the best state according to this rapid adjustment process. Compare performance again;

6. The greater the amount of electret masterbatch added, the better the electrostatic effect, but the greater the impact on the fabric, it needs to be balanced, and the premise is to make the fabric well.
