Definitions
- the invention relates to a method for producing a crimped multifilament thread (BCF) according to the preamble of claim 1 and to an apparatus for producing a crimped multifilament thread (BCF) according to the preamble of claim 8.
- BCF bulk continuous filament
- pile yarn which is previously produced in a melt spinning process.
- the thread closing of the filaments of the thread is ensured in the manufacturing process essentially by a plurality of intertwining knots, which are generated before winding the thread on the thread.
- interlacing nodes are generated by a compressed air treatment of the thread.
- knotting nodes are usually generated by a turbulence of the filaments of the thread.
- a turbulence of the filaments of the thread Such a method and such a device are described, for example, in EP 0 784 109 Bl.
- the thread is passed through a treatment channel of a swirling nozzle, in which a continuous stream of compressed air is directed across the thread.
- the geometric design of the treatment channel and the overpressure of the compressed air are intense turbulence up to interlacing knots on the thread.
- the number of entanglement knots per unit of length produced on the thread and the knot formation of the filaments in the thread can not be produced reproducibly due to the thread vibrations even with constant overpressure of the compressed air, so that the knot stability and the distances between the entwining nodes depend more or less on the vibration behavior of the thread and in larger tolerances.
- Such variations in node stability of the interlace nodes as well as the variation in the number of interlace nodes per unit length of thread result in coloration of undyed threads being very different depending on node stability and node count.
- a further object of the invention is to provide a method and an apparatus of the generic type for producing a crimped multifilament yarn, in which a predetermined pattern of intertwining knots can be produced on the thread and used for visual patterning in a carpet product.
- This object is achieved according to the method for the fact that a pulse train of compressed air pulses with a predetermined frequency is directed to the thread to generate the entanglement.
- the inventive device solves the problem in that the treatment device has a controllable blowing means for generating a periodically on the thread-directed compressed air pulse.
- the invention is based on the recognition that the interlacing nodes in the thread can significantly influence the visual appearance of a carpet product. For example, when processing a multi-colored thread in a single-ply tufting machine, it was possible to create a carpet that displays superimposed regular patterns, so-called repeat strips. It has been found that this effect can be influenced by varying the stability of the accounts and by varying the intersections of the interlacing nodes in the thread. In that regard, the invention has the particular advantage that, depending on the desired pattern in the carpet this effect can be harnessed. Thus, it is well known that a compressed air pulse directed at the thread leads to a spontaneous and pronounced formation of intertwining nodes.
- the sequence of a multiplicity of compressed-air pulses having a predetermined frequency makes it possible to produce a pattern of the interlacing nodes on the thread.
- the pulse train of recurring pulses of compressed air ensures a reproducible pattern of knotting nodes on the current thread. In this case, uniform or even uneven sequences of intertwining nodes can be generated on the thread.
- the method variant is preferably used, in which the frequency of the pulse train of compressed air pulses is set in response to a thread speed such that at least one number of 5 to 35 interlacing nodes on the thread per meter length be generated.
- the desired number of intertwining nodes can be preset on the thread.
- the method according to the invention can be used particularly advantageously at relatively high yarn speeds.
- the guide properties of the thread required for the formation of the intertwining nodes can be adjusted individually by the driven godets.
- the variant of the method in which the compressed air pulses are generated by a rotationally driven nozzle ring with a thread running track with at least one nozzle bore in the thread running track is particularly advantageous in order to reproducibly generate the compressed air pulses at a relatively high frequency.
- the nozzle bore is periodically connected by rotation of the nozzle ring with a pressure source, so that a compressed air flow is passed through the nozzle bore in the thread running track for a short period of time.
- Another particular advantage of the generation of compressed air pulses by a driven nozzle ring is given by the fact that the presetting of the frequency of the pulse train is possible by a drive of the nozzle ring.
- the variant of the method is particularly kart, wherein the nozzle ring for adjusting the frequency of the pulse train is driven at a predetermined peripheral speed.
- the method variant is particularly advantageous, in which the peripheral speed of the nozzle ring per unit time is changed periodically. In this way, it is advantageous to produce irregular patterns at interlacing nodes in the thread.
- Such irregularities of the patterns can also be achieved by employing a nozzle ring with circumferentially unevenly distributed nozzle bores which are driven at a constant or varying peripheral speed.
- the device according to the invention has the particular advantage that in the treatment of the thread, the consumption of compressed air is reduced to a minimum.
- a compressed air stream for the treatment of the thread is discharged.
- no compressed air consumption takes place, so that the consumption compared to conventional permanently operating turbulators is significantly reduced.
- the blowing agent by a rotationally driven Nozzle ring formed with a circumferential thread running track and at least one opening into the thread running track nozzle bore.
- the nozzle ring is coupled to a compressed air source such that upon rotation of the nozzle ring, the nozzle bore is periodically connectable to the compressed air source.
- a compressed air source such that upon rotation of the nozzle ring, the nozzle bore is periodically connectable to the compressed air source.
- the peripheral speed of the nozzle ring which is proportional to the frequency of the pulse sequence of the compressed air pulses, can be changed in particular by the fact that the nozzle ring is coupled to an electric motor and a control unit associated with the electric motor. By specifying a set frequency, the pulse sequence of the compressed air pulses can be generated at a constant frequency.
- the development of the invention is particularly advantageous, in which the electric motor is designed as an unregulated asynchronous motor.
- the random deviations of the uncontrolled asynchronous motor can be used in order to be able to generate an irregular pattern of the interlacing nodes in the thread.
- the device according to the invention is preferably designed such that the control device is connected to a central machine control unit.
- all parameters and machine settings that are essential for the production of the thread can be entered directly. Desired ratios between the yarn speeds of the godets and the peripheral speed of the nozzle ring can be evaluated directly in the machine control unit and corrected accordingly.
- the nozzle ring is disposed within an enclosure with a thread inlet and a thread outlet. The encapsulation is formed with the thread inlet and the thread outlet such that the thread contacts the nozzle ring at least with a minimum wrap angle and is guided in the thread running track.
- the encapsulation is preferably formed multi-walled, wherein an inner wall is preferably formed from a Schallisoliermaterial.
- the nozzle ring is arranged with the encapsulation on a front side of a support wall, wherein the support wall carries on a rear side of the electric motor of the nozzle ring.

- the thread inlet thread guide 31 and the outlet thread guide 32 can be formed by deflecting pins or pulleys. In a thread guide arranged outside the encapsulation, it is also possible to form the yarn guides 31 and 32 directly by driven godets, so that the nozzle ring 18 could be arranged directly in the yarn path between the godets.

- the nozzle ring 18 In order to perform the compressed air pulses as a pulse train with a predetermined frequency, the nozzle ring 18 is driven via the electric motor 34 at a predetermined peripheral speed. Depending on the desired frequency, the peripheral speed of the nozzle ring 18 can be adjusted in relation to the yarn speed of the yarn 16 such that the yarn 16 is guided with slip or with a conveying effect. It has been found that the setting range of the circumferential speed is selected such that the circumferential speed of the nozzle ring 18 is set to a value which is smaller or larger by a maximum of 50% in relation to the yarn speed of the yarn 16.
- the electric motor by an unregulated asynchronous motor.
- the motor slip can advantageously be used to produce an irregular pattern of entanglement nodes on the thread 16.
- the embodiment of the blowing means shown in Figs. 4 and 5 is thus particularly suitable for producing both uniform or non-uniform patterns of entangling knots in the thread. Such patterns of interlacing knots in the thread can thus be used to advantage to obtain visual effects in the final product of a carpet product.
