After the melt is extruded through the spinneret, the temperature is relatively high, and the temperature of the filament is about 250℃-280℃. At this time, the side wind will cause the filament to cool rapidly, and the surface of the filament will cool and solidify, while the temperature inside the filament is still relatively high. The inside and outside of the filament are heated unevenly, which will affect the unevenness of the filament and the decline of mechanical properties such as strength.
