Embodiment Construction

[0026] 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 .

[0027] 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 .

[0028] 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 device for producing synthetic fibers. In said method, a plurality of extruded fiber strands are guided through a temperature- and humidity-controlled treatment medium in order to be cooled, heated, fixed and / or dried. In order to produce the fibers in a particularly energy-efficient manner, according to the invention the treatment medium is at least partiallygenerated from a waste gas stream of a small-scale CHP unit. To this end, the treatment device is connected to the small-scale CHP unit via a waste gas line.

Description

technical field [0001] The invention relates to a method for producing synthetic fibers according to the preamble of claim 1 and a plant for producing synthetic fibers according to the preamble of claim 8 . 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 important for the end product, heat treatments in the form of heat are also known which are used in particular when drawing fiber slivers. This heat treatment on the fiber sliver thus forms a major production step in the process of manufacturing synthetic fibers. [0003] Thus, for examp...
