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. Various screw barrel sets with customized design for melt blown non-woven fabric extrusion machines are available from Ningbo Jinyi Precision. Parameters Material:38CrMoAl…
