Definitions
- the invention relates to a method for melt spinning a plurality of multifilament threads made of a thermoplastic material according to the preamble of claim 1 and a device for carrying out the method according to the preamble of claim 9 Extruder or a pump, melted into a polymer melt.
- the polymer melt is fed to a spinneret, which has a nozzle plate with a plurality of nozzle bores on its underside.
- the spinneret which is preferably referred to in the art as a nozzle package
- the polymer melt is through the nozzle bores of the nozzle plate. pressed so that a large number of fine filament strands are formed.
- the extruded filament strands are cooled and then combined into one or more threads. After treatment, the thread or threads are wound into bobbins.
- the invention now relates to the known methods and devices in which the filament strands extruded through a spinneret are divided into a plurality of filament bundles and the filament bundles are each combined into a thread.
- a spinneret with an area-wide arrangement of nozzle bores in the nozzle plate is used in order to extrude a large number of filament strands.
- the filament strand After the filament strand has cooled, it is divided into two bundles of filaments by means of a dividing device designed as a preparation thread guide, and each of the filament bundles is combined into a thread. After treatment, the threads are wound up separately into bobbins.
- Another object of the invention is to produce a large number of threads spun in parallel in the most compact possible arrangement.
- the invention was also not suggested by the methods and devices for producing multicomponent threads known in the prior art, as are known, for example, from DE 101 43 070 AI.
- Such methods and devices are fundamentally based on the fact that two different types of polymer are melted by two separate melt sources, which are then brought together within a spinneret in order to form a multi-component thread.
- the filament strands extruded from at least two different types of polymer are combined into a thread after the extrusion.
- the invention has the particular advantage that essentially no preferred or less preferred zones of the melt distribution form on the nozzle plate.
- the polymer melt is fed into several separate partial melt streams of the spinneret and guided separately within the spinneret, so that each of the partial melt streams is extruded into one of the filament bundles. This achieves a uniform extrusion and a uniform formation of the spin titer when extruding the filament strand. It has proven to be particularly advantageous that the number of partial melt streams should be equal to the number of threads melt-spun through the spinneret. Each filament bundle formed after dividing the filament strand is assigned a separately supplied partial melt flow.
- the device according to the invention has a spinneret which is connected to the melt source via a plurality of feed lines, each of the feed lines carrying a partial melt flow.
- the improved uniformity of the thread production could already be achieved with a process variant according to the invention, in which the partial melt flows are brought together in a distribution chamber before the nozzle plate penetrates.
- the spinneret preferably has a plurality of melt channels designed as guide means, which are connected on the one hand to the feed lines and on the other hand to the central distributor chamber.
- Nozzle plates inside the spinneret are guided separately.
- a separate distributor chamber is assigned to each melt channel within the spinneret.
- the technical advantage achieved by the invention could be further improved by filtering the partial melt streams within the spinneret immediately before extrusion.
- a plurality of filter elements are advantageously assigned to the melt channels, so that each partial melt stream can be filtered separately.
- the development of the invention is used according to the invention, in which a multiple pump is arranged between the melt source and the spinneret. Each of the partial melt streams is generated by the multiple pump and fed to the spinnerets via the incoming lines.
- the method according to the invention and the device according to the invention are preferably used in the further development of the invention, in which the spin-r-nozzle is designed as a round-spinneret with a flat arrangement of nozzle bores in the nozzle plate.
- the cooling device is preferably provided by a cross-flow blowing or a radial blowing with a cooling air flow directed inwards from the outside.
- the further development of the invention is preferably used, in which the filament strands are extruded on the nozzle plate by means of an annular spinneret with an annularly distributed arrangement of the nozzle bores.
- the ring-shaped arrangement of the guided filament strands can preferably be sealed by radial blowing with cooling air flow directed from the inside out.
- each of the threads can be treated individually and wound into a spool. The treatment takes place depending on the further processing, so that the threads can be produced as a so-called POY or FDY yarn.
- the threads could then be prepared, swirled, warmed, cooled or crimped for treatment.
