METHOD AND DEVICE FOR PRODUCING SPUNBONDED FABRIC
A process for the production of spunbonded nonwoven (1) and a device for this purpose are shown, wherein a spinning mass (2) is extruded through a plurality of nozzle holes of at least one spinneret (3) to form filaments (4) and the filaments (4) are charged with a drawing air stream to be drawn in...

| description | A process for the production of spunbonded nonwoven (1) and a device for this purpose are shown, wherein a spinning mass (2) is extruded through a plurality of nozzle holes of at least one spinneret (3) to form filaments (4) and the filaments (4) are charged with a drawing air stream to be drawn in an extrusion direction, wherein the filaments (4) are deposited on a perforated conveying device (9) to form a spunbonded nonwoven (1) and wherein the spunbonded nonwoven (1) is subsequently subjected to at least one washing (10) and one drying (12) by means of hot air (15), with, in each case, one exhaust air stream (18, 19) being discharged during the drawing and washing (10). So as to be able to reduce the energy consumption in the process during the drying of the spunbonded nonwoven without decreasing the product quality, it is suggested that the hot air (15) for drying (12) is generated at least partially by preheating an air stream (16) by means of one of the exhaust air streams (18, 19) from the drawing and washing (10). |
