Abstract

The invention relates to a process (100, 101) for the production of spunbonded nonwovens (1.1, 1.2, 1.3) and a device (200, 201) for the production of spunbonded nonwovens (1.1, 1.2, 1.3), wherein, in the process (100, 101), a spinning mass (2) is extruded through a plurality of nozzle holes (4.1, 4.2, 4.3) of at least a first spinneret (3.1) and a second spinneret (3.2) to form filaments (5.1, 5.2, 5.3) and the filaments (5.1, 5.2, 5.3) are drawn, in each case, in the extrusion direction, with the filaments (5.1) of the first spinneret (3.1) being deposited on the conveyor belt (9) to form a first spunbonded nonwoven (1.1) and the filaments (5.2) of the second spinneret (3.2) being deposited on the conveyor belt (9) to form a second spunbonded nonwoven (1.2) over the first spunbonded nonwoven (1.1) in order to obtain a multi-layered spunbonded nonwoven (10). For increasing the throughput of the process, it is suggested that the multi-layered spunbonded nonwoven (10) is separated into at least the first spunbonded nonwoven (1.1) and the second spunbonded nonwoven (1.2) in a subsequent step and the first and second spunbonded nonwovens (1.1, 1.2) after separation each undergo a hydroentanglement (15.1, 15.2) and optionally a drying (12) individually and/or are each wound up individually.
