Spunbond is one of the most popular methods to produce polymer nonwovens. The process is based on melt spinning technology. The melt is forced through a spinneret with a large number of holes by a spinning pump. A quench air duct located below the spinneret continuously supplies regulated air to cool the filament. There is also a continuous supply of auxiliary room temperature air. In the whole working width of the production line, the negative pressure fan sucks filament and mixed air from the spinneret and cooling chamber.
