The melt-blown fabric is produced by the melt-blown process. Its equipment mainly includes screw extruder, melt pump, screen changer, melt-blown device, winding device machine, air system (heat fan and heater), etc. The function of the screw extruder is to melt the sliced material; the function of the melt pump is to accurately measure, control the output and the fineness of the fiber, and continuously and uniformly transport the melt to the spinneret. The role of the screen changer is to filter out impurities in the melt to avoid clogging the spinneret holes. The function of the winding device is to pack the melt-blown cloth into rolls. The function of the air system (heat fan and heater) is to provide the temperature and pressure of the hot air used in the spinning air flow stretching.
