Definitions
- the invention relates to a method for producing BCF threads according to the preamble of claim 1 and a device for producing BCF threads according to the preamble of claim 10.
- So-called BCF (bulked continous filament) threads are produced in a one-stage spinning process, the melt-spun and crimped BCF threads being used essentially for carpet yarns.
- BCF powder continous filament
- a large number of strand-like filaments are extruded, cooled, bundled together in a thread, stretched, crimped and wound up into a bobbin.
- the filament strands brought together into a thread are extruded in bundles by means of a spinneret, which has a nozzle bore on the underside of each of the filaments.
- a spinneret which has a nozzle bore on the underside of each of the filaments.
- EP 0 363 317 A2 discloses a method and a device in which the filament bundles forming a thread are extruded through a respective spinneret.
- the spinnerets are arranged next to one another in an annular arrangement, so that the individual filament bundles are guided in an annular arrangement for cooling.
- the cooling takes place through a cooling air flow generated from the inside to the outside. After cooling, the filament bundles are brought together to form the threads, then drawn, textured and wound into bobbins.
- the methods and devices known in the prior art generally have the disadvantage that the filament strands are extruded in bundles, so that a high filament density is achieved during extrusion to form threads with relatively large total titers, which does not ensure uniform cooling of all filament strands.
- the bundle-shaped arrangement of the filaments during extrusion also has the disadvantage that a cooling air flow directed from the outside onto the bundle of filament strands means that filament strands have a lower cooling effect inside the bundle than filament strands which are guided at the edge of the bundle.
- the requirement for uniformity is particularly high since a further processing process is not provided. Cooling is of particular importance because it directly influences the physical characteristics of the filaments.
- the invention is based on the object of providing a method and a device for producing BCF threads, in which the filaments brought together to form threads have a high degree of uniformity in quality.
- Another object of the invention is to provide a method and a device of the type mentioned at the outset with which BCF threads can be produced with a high melt throughput and high filament density.
- the solution is provided by a method with the features of claim 1 and by an apparatus with the features of claim 10.
- the invention completely turns away from the known plant concepts in which the filaments are divided to form the threads already during the extrusion.
- the invention is based on the fact that a division of the filament strands to form the threads is only necessary after the extrusion.
- the extrusion and cooling of the plurality of filaments that form several threads is standardized.
- the multiplicity of filaments are extruded through a nozzle means as an annular filament sheet.
- the annular filament sheet is then cooled by a cooling air flow directed from the inside out.
- individual segments of the ring-shaped filament family are brought together to form a thread.
- the particular advantage of the invention is given in that each of the filaments guided within the filament sheet can be cooled uniformly.
- the conditions for extruding and cooling the filaments remain unaffected by the total titer of the individual threads subsequently formed.
- the number of filaments per thread can be increased by combining a larger segment of the annular filament family.
- the invention was also not suggested by the fact that spinning devices for the production of staple fibers are known in the prior art, for example from EP 1 247 883 A2, in which a filament array arranged in a ring is extruded and brought together to form a spinning cable.
- Such methods and devices are designed to extrude, cool and combine a large number of filaments. In doing so preferably several ring-shaped filament shares connected to a total tow.
- Such methods and devices are, however, completely unsuitable for producing a plurality of separately guided and treated threads.
- the so-called ring spinneret is particularly advantageously suitable for extruding the annular filament sheet forming the BCF threads.
- Such ring spinning nozzles have a plurality of nozzle bores on their underside, which are formed in an annular arrangement.
- the nozzle bores are preferably symmetrical in a plurality of rows of bores formed concentrically with one another. In this way, relatively large filter areas can be realized, which enables a high throughput per ring spinneret of more than 150 kg h.
- the development of the invention is particularly advantageous in which the annular filament family is extruded through a plurality of ring-hole segments forming the annular arrangement of nozzle bores in the annular spinneret, and in which the one through one of the Ring-hole segments extruded part of the filament sheet is brought together to form one of the threads. This advantageously ensures that each of the threads has the same number of filaments.
- the ring hole segments of the ring spinneret are supplied with a polymer melt by a common distribution chamber. Additional distribution or filter elements can be arranged upstream of a nozzle plate containing the nozzle bore.
- the development of the invention in which a plurality of separate distributor chambers are formed within the ring spinneret, each of which is connected to a ring hole segment or a group of ring hole segments and through which a plurality of polymer melts onto the associated ring hole segments distributed, is particularly advantageous to produce multicolor BCF threads.
- a plurality of polymer melts for extruding the filament sheet are fed to the assigned ring hole segments of the ring spinneret via the distribution chamber and extruded.
- the cooling air generated by a blow candle has proven particularly useful.
- the gas-permeable jacket of the blow candle generates a uniform cooling air flow in every radial direction. Zones of different gas permeability can be formed on the jacket of the blow candle in order to produce different cooling zones for cooling or certain blowing profiles of the cooling air.
- a further particularly advantageous development of the invention is given in that the filament sheet is prepared before being divided into the threads. Due to the ring-shaped arrangement of the filament coulter, uniform application to all filaments can be produced by external or internal preparation rings.
- the dividing device can be formed below the cooling device by a plurality of thread guides which are arranged at a distance on a distributor ring in accordance with the segment-shaped division of the filament sheet.
- the distributor ring can be arranged inside the filament sheet or outside the filament sheet.
- a particularly advantageous development of the invention is given by the division of the thread guides of the dividing device in one plane.
- the further treatment of the threads in the thread running plane by stretching, crimping and winding up can thus be connected directly.
- BCF threads of various types and from different thread materials such as polyamide, polypropylene or polyester can be produced.

- the winding device 5 is also only shown as a diagram in which a projecting winding spindle 11 is kept driven on a spindle carrier 12. Three coils 10.1, 10.2 and 10.3 are wound side by side on the winding spindle.
- Such winding machines for winding BCF threads are preferably formed by machines which have two winding spindles which are held on a movable support in such a way that a continuous winding of the threads by changing the winding spindle is possible.
- the additional means such as a traversing device and a pressure roller are not shown here.
- Such a winding machine is known for example from WO 96/001222, so that reference is made to this document at this point.
- a polymer melt for example made of polyamide or polypropylene, is first fed in the spinning device 1 through the spinning pump 15 to the annular spinneret 17.
