Embodiment Construction

[0025] exist figure 1 A first embodiment of an apparatus for producing synthetic fibers according to the invention is shown schematically in cross section. This exemplary embodiment shows a melt-spinning device 1 and a treatment device 8 which is arranged as a cooling device 9 directly below the spinning device 1 .

[0026] In this exemplary embodiment, the spinning device 1 shows a spinning station with spinning nozzles 5 on the underside of the spinning beam 4 . The spinning nozzle 5 is connected to the spinning pump 3 via a melt pipe 6.1. The spinning pump 3 is connected to a melt distribution system 6 which is coupled to the extruder 2 . Such a melt distribution system 6 extends over a plurality of spinning positions, wherein a plurality of spinning nozzles can be held on the heated spin beam 4 .

[0027] The spinning nozzles 5 held on the underside of the spinning beam 4 can be designed as circular nozzles for producing filaments or as rectangular nozzles for producing...

Abstract

The invention relates to a method and a device for producing synthetic fibers, in which a plurality of extruded fiber strands is guided through a temperature-regulated treatment medium for cooling, heating, shaping and / or drying. In order to allow particularly energy-efficient fiber production, according to the invention, the treatment medium is at least partially generated from the exhaust gas flow of the central thermal power plant. For this purpose, the treatment unit is connected to the central thermal power station via an exhaust gas pipe.

Description

technical field [0001] The invention relates to a method for the production of synthetic fibers, in which a plurality of extruded fiber strands are guided through a temperature-regulated treatment medium for cooling, heating, shaping and / or drying . The invention also relates to a plant for the production of synthetic fibers with a melt-spinning device for producing a plurality of fiber slivers and for cooling, for heating, for shaping and / or for drying the fiber slivers Processing device. Background technique [0002] It is customary in the production of synthetic fibers to extrude fibers from a polymer melt. Depending on whether the fibers are used for the production of filaments, nonwovens or for the production of staple / staple fibers, different treatments must be carried out on the fiber slivers. It is therefore known to carry out a heat treatment in the form of cooling directly after extrusion of the fiber strand. In order to obtain the physical properties which are...
