| titleOfInvention | Manufacturing method of spunbonded nonwoven fabric |
| abstract | A spinning mass (2) is extruded through the nozzle holes (4) of one or more spinnerets (3, 30) to form filaments (5, 50), said filaments (5, 50) being pulled in the extrusion direction and first It is deposited on the conveying device 9 to form a spunbonded nonwoven fabric 1 , and the spunbonded nonwoven fabric 1 is washed 10 or more times. In order to increase the throughput of the process without loss of quality, the spunbonded nonwoven fabric 1 is at least partially washed on the perforated second conveyer 13 at a lower feed rate compared to that of the first conveyer 9 . It is proposed to be (10), wherein during washing (10) a washing solution is sprayed onto the spunbonded nonwoven fabric (1) and the washing solution is discharged at least partially through the perforated second conveying device (13). |
