Abstract: A process for the production of spunbonded nonwoven (1) and a device for this purpose are shown, wherein a spinning mass (2) containing solvent is extruded through a plurality of nozzle holes of at least one spinneret (3) to form filaments (4) and the filaments (4) are drawn, in each case, in the extrusion direction, wherein the filaments (4) are deposited on a perforated conveying device (9) to form a spunbonded nonwoven (1) and, subsequently, are subjected to washing (10) for washing out the solvent from the filaments (4) and to hydroentanglement (11). So as to allow an inexpensive and efficient production of hydroentangled spunbonded nonwoven by means of the process, it is suggested that fresh water (12) is supplied to the hydroentanglement (11) and the waste water (13) from the hydroentanglement (11) is supplied to the washing (10) as wash water (14).

Abstract: 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).

Abstract: A micro-mechanical component including a support element and a cantilever with integrated electrical functional element to which at least two electrical supply lines implemented as printed conductors on the cantilever are routed. The invention proposes to arrange at least one each of the supply lines on the two opposite flat surfaces of the cantilever and/or the support element. The functional element is supplied by the first supply line on a first flat surface, with the second supply line on the opposite flat surface serving as return line.
