Embodiment Construction

[0029] FIG. 1 shows an exemplary embodiment of an apparatus according to the invention for melt spinning a plurality of strand-like monofilaments. The device has a spinning device 1 and a cooling device 2 located directly below the spinning device 1 . The spinning device 1 comprises a melt inlet 3 which is connected, for example, to a melt source (not shown here), such as an extruder or a pump. The melt inlet 3 leads to a spinning head 4 . On the underside of the spinneret 4 are provided one or more nozzle assemblies 5 containing a plurality of spinneret holes to extrude a plurality of strand-like monofilaments 6 .

[0030] A cooling channel 7 of the cooling device 2 surrounding the emerging filaments 6 is arranged below the nozzle assembly 5 . The cooling channel 7 is connected via an air inlet channel 8 to an outlet of a cooling fluid source 9 . Fresh air is supplied to the cooling fluid source 9 via an air inlet 10 arranged on the opposite side of the air supply channel ...

Abstract

The invention relates to a method for cooling down melt-spun filaments and to a device for melt-spinning a plurality of continuous filaments. According to the inventive method, the filaments melt-spun by means of a spinning device are cooled down in a cooling device by means of conditioned cool air. In order to condition the cool air, the wet steam required is generated by a plurality of steam generators that are linked in parallel with the coolant source. The number of steam generators can thus be adapted to the required amount of steam in such a manner that at least one of the steam generators can be switched off for maintenance.

Description

technical field [0001] The invention relates to a method for cooling melt-spun monofilaments, in which conditioned or humidified cooling air is fed into cooling channels surrounding the monofilaments by means of a cooling medium source, wherein the cooling is previously conditioned by moist steam air; and a device for melt spinning a plurality of strands (rope) of monofilaments, said device having a spinning device for extruding the monofilaments and a cooling device for cooling the monofilaments, wherein the cooling device has a Cooling channels passed through by the filaments and a source of cooling fluid connected to the cooling channels. Background technique [0002] During melt spinning, a plurality of strand-shaped monofilaments composed of a polymer melt are extruded through a plurality of spinneret holes of a spinning nozzle by means of a spinning device. The freshly spun monofilament strands are cooled after exiting the spinning unit to be combined into filaments o...
