Problems solved by technology

Therefore said known method and known device are completely unsuitable to be able to carry out as quantitative as possible wetting to filament
In addition, high losses occur when wetting the filaments, since the fluid under pressure flows out automatically via the filament inlet and the filament outlet

Embodiment Construction

[0023] figure 1 An exemplary embodiment of the device according to the invention for carrying out the method according to the invention for producing synthetic filaments, in particular to form IDY filaments, is shown in a view. This exemplary embodiment shows a spinning device 1 , a processing device 2 and a winding device 3 , which are arranged one behind the other in the yarn flow. These devices are typically used to melt spin, process and wind multiple parallel-guided filaments. but figure 1 The filament flow for only one filament is shown in .

[0024] For the melt spinning of multi-filament filaments, the spinning device 1 has a heatable spinning head 4 which has a spinneret 5 with a large number of nozzle holes on its underside and a melting nozzle on its upper side. body entrance 6. The melt inlet 6 is connected to a melt source (not shown here), for example an extruder. Further components for guiding and conveying the melt, such as spinning pumps, are usually arra...

Abstract

The present invention relates to a method and a device for melt spinning, treating and coiling synthetic filament, wherein a plurality of spun single filaments are combined to a filament. The filament is treated and coiled. Furthermore the filament is wetted before winding with chemical fluid. For quantitatively wetting the filament with a high long-filament speed in a range of 5000m / min to 8000m / min, the filament is introduced to pass through a vertical liquid column of the fluid according to the invention, wherein, the height of the liquid column is variablefor facilitating quantitative dispensing. Therefore, a liquid column chamber which is used for accommodating the liquid column and is vertically oriented is formed in a wetting device. The liquid column chamber extends between an upper filament inlet and a lower filament outlet.

Description

technical field [0001] The invention relates to a method for melt spinning, processing and winding synthetic filaments according to the preamble of claim 1 and a method for carrying out the method according to the preamble of claim 8 installation. Background technique [0002] During the production of synthetic filaments in the melt-spinning process, the properties of the filaments to be produced are adapted as far as possible to the subsequent further processing of the filaments or to the subsequent further processing of the filaments. Therefore, in the production of filaments for technical applications, which are also known in the art as so-called IDY yarns, wetting is usually carried out with chemical fluids in preparation for the application of tackifiers. For example, for the production of fiber-reinforced rubber products, a high degree of bonding of the synthetic fibers to the rubber material is necessary. This connection is produced by a corresponding tackifier, whi...
