Nowadays, #Covid19 virus spreading all over the world and has became a pandemic, lots of countries didn't control the situation in the beginning which makes thousands of lives died so far. More and more goverements decreed an order to public before that required their citizens need to wear face mask when they participate in social activities and stay home as much as possible . Even if the situation is much better than before, people will not relax their vigilance.  People have got into a habit of wearing face mask when they go out from home.  It leads the demand for face mask significantly increased these days,  the demands and prices of raw materials for producing face mask going up as well.

Melt-blown nonwovens, one of important materials for producing face mask, has became very hot lately.  Producing a melt-blown nonwovens, polymer material is gonna be melted and fused in a smelter. When material is completely fused, it will be extruded and blown through plenty of ultra-fine holes in a spinneret plate under high tempreture and high pressure. When hot polymer material is blown out and contact with cold air, it will be freezed immediately and perfectly attach to nonwovens.  The most important part during this procedure is polymer material blown from plenty of ultra-fine holes in spinneret plate. Whether the polymer attaching on nonwovens is even or not, it depends on the ultra-holes in spinneret plate.
