Screw Barrel For Melt Blown Non-Woven Fabric extrusion

 The melt blown process is a non-woven  manufacturing system involving direct conversion of a polymer into  continuous filaments, integrated with the conversion of the filaments  into a random laid non-woven fabric.

The melt  blown process involves the attenuation of the filaments using  high-velocity hot air streams that impinge on the extruded filaments as  they are emerged from the extrusion nozzles to obtain much finer  filaments.

Melt  blown Non-woven as the filter of the face masks, in recently because of  the COVID-19 outbreak, the demand is increased so much. And the melt  blown non-woven extruder becomes the hot sale machine besides the face  mask making machine.
