| titleOfInvention | Process for the production of spunbonded nonwoven |
| abstract | The invention relates to a process (100) for the production of spunbonded nonwoven (1) wherein a spinning mass (2) is extruded through the nozzle holes (4) of at least one spinneret (3, 30) to form filaments (5, 50), the filaments (5, 50) are drawn in the extrusion direction and deposited on a first conveying device (9) to form the spunbonded nonwoven (1), and wherein the spunbonded nonwoven (1) is subjected to at least one washing (10). For increasing the throughput of the process without losses of quality, it is suggested that the spunbonded nonwoven (1) is subjected to the washing (10) at least partially on a perforated second conveying device (13) with a lower conveying speed with respect to that of the first conveying device (9), wherein the spunbonded nonwoven (1) is sprayed with washing liquid during the washing (10) and the washing liquid is discharged at least partially through the perforated second conveying device (13). |
