| titleOfInvention | Method for producing a spunbond nonwoven |
| abstract | The invention relates to a method (100) for producing a spunbond nonwoven (1). A spinning material (2) is extruded through the nozzle holes (4) of at least one spinneret (3, 30) in order to form filaments (5, 50), and the filaments (5, 50) are stretched in an extrusion direction and laid on a first conveyor device (9) in order to form the spunbond nonwoven (1), said spunbond nonwoven (1) undergoing at least one washing process (10). The aim of the invention is to increase the throughput of the method without any loss in quality. This is achieved in that the spunbond nonwoven (1) undergoes the washing process (10) at least partly on a perforated second conveyor device (13) with a slower conveyor speed than the first conveyor device (9), wherein the spunbond nonwoven (1) is sprayed with washing fluid in the washing process (10), and the washing fluid is at least partly discharged through the perforated second conveyor device (13). |
