Definitions

  • the invention relates to a method according to the preamble of claim 1 and an arrangement according to the preamble of claim 4.
  • Colored yarns made from endless synthetic fibers are produced by mixing several bundles of threads of different colors or dyeability. They are used for the manufacture of textile piece goods, in particular carpets and upholstery fabrics.
  • the individual components In order to achieve a pleasing, lively colorful effect on the end product, the individual components should be evenly mottled. The average distance between the crossings of the differently colored components is of great importance for the overall impression of the finished piece goods. In general, the interlacing must not be so intense that the individual components no longer stand out separately; such complete mixing leads to a low-contrast, dull appearance of the piece goods. On the other hand, the average distance between the interconnections should not be too large, because this easily creates a garish, unbalanced impression.
  • the value of the yarn is reduced if, due to accidental interference or systematic influences, individual colors or structures alternate over longer distances. This leads to undesired stripes, streaks or moire-like structures on the finished piece.
  • the interdependency is not very controllable - and depends on random factors, e.g. of fluctuations in pressure, temperature or thread tension. If the process parameters change, e.g. Thread titer or throughput speed, the effect on the color structure of the finished yarn is not readily predictable. Therefore, it is difficult to reproducibly set and keep a desired effect constant.
  • a disadvantage of pneumatic swirling is also the high air consumption and the high noise level caused by the escaping air.
  • the present invention has for its object to provide a method of the type specified in the preamble of claim 1, with which a desired color structure can be selected from a wider range of possibilities and produced in a reproducible manner.
  • the second task is to provide an arrangement with which the method can be carried out easily and with little effort.
  • the first-mentioned object is achieved according to the invention by the measures specified in the characterizing part of claim 1.
  • the invention is based on the knowledge that the color structure of the crimped yarn can be influenced by changing the relative arrangement of the individual threads entering the crimp in short time intervals.
  • the measure specified in claim 2 leads to an improvement in the cohesion of the crimped yarn.
  • the method can be carried out according to claim 3 in the course of a multi-stage overall process, so that a special operation for the production of the colored yarn is not required.
  • the second object is achieved by the characterizing features of claim 4.
  • Claim 6 specifies another, also very simple version of a traversing thread guide.
  • the embodiment according to claim 7 is characterized by a particular variety of possible variations.
  • the feature of claim 9 opens up a possibility of variation without increased effort.
  • the feature of claim 10 enables simplification in most cases, one or more threads remaining unchanged.
  • the cohesion of the yarn can be improved behind the crimping device.
  • Suitable crimping devices belong to the prior art. This includes e.g. a pneumatic crimping chamber according to US Pat. No. 3,849,844, a compression crimping chamber according to GB-PS 1,057,417 or a gear crimping device according to DE-AS 1 292 302.
  • a second thread b is guided over a slit drum 4, which on its outer surface in a known manner is provided in a returning thread guide groove and rotates in an axis parallel to the axis of the thread guide roller 1.
  • the thread b lying in the thread guide groove is moved in a known manner in the direction of the drum axis, i.e. transversely to its direction of movement and the direction of movement of the thread a, back and forth.
  • the slot drum 4 and the thread guide roller 1 are arranged parallel to the axis and relative to one another such that the central plane of the thread guide roller 1 lies approximately in the middle of the traversing area of the slot drum 4. Therefore, the thread b is guided alternately on one side and on the other side of the thread a onto the godet 2, as illustrated in FIG. 2. In the mutual position that the threads a and b occupy on the godet 2, they are drawn into the crimping device 3.
  • the thread produced in this way shows a color change which is caused by changing the traversing speed, i.e. by changing the speed of the slit drum 4, in a predictable and reproducible manner.
  • the traversing speed is limited by the speed of the thread and the distance between slotted drum 4 and godet 2 upwards.
  • the duration of a single stroke of the traversing should be at least as long as the time it takes for a certain point on the thread to get from the slit drum 4 to the godet 2 or, generally speaking, to a point behind which the relative position of the individual threads is can not change until it enters the crimping device.
  • the maximum traversing speed is greater for a given thread speed, the shorter the distance between slot drum 4 and godet 2 is kept.
  • the threads a and b On the godet 9, to which the threads a and b as well as the thread c arrive, the threads a and b therefore run alternately on one and on the other side of the thread c, which is in the middle, as in FIG. 4 indicated.
  • the threads reach the drafting device 11 from the godet 9, their mutual position remaining unchanged.
  • the threads are drawn into the crimping device 12.
  • a mixed thread emerges from the crimping device 12, the color structure of which is determined by the speed of the slit drum 10.
  • the thread For the purpose of cooling, the thread is deposited on a sieve drum 13 and from there in the usual way to a winding unit 14.
  • the machine partially shown in FIG. 3a differs from the machine according to FIG. 3 in that instead of the slot drums 10 there are two slot drums 10a and 10b arranged one above the other, the axes of which are slightly offset from one another in the horizontal direction. Each of the threads a, b is therefore guided on its own slit drum without touching the other.
  • the slot drums 10a and 10b can be driven at different speeds.
  • the points of interweaving of thread a with thread c have the same distances as the points of interweaving of thread b with thread c.
  • the spacing of the interweaving points for thread a can be greater or smaller than that of thread b as desired. Accordingly, the device according to FIG. 3a offers even more possibilities for arbitrarily changing the play of colors.
  • FIG. 5 shows a spin draw texturing system Machine in which three differently colored or differently dyeable threads a, b, c are drawn off from the nozzles 17, 18, 19 of the spinning beam 20 by means of a take-off godet 15 with a feed roller 16. Between the withdrawal godet 15 and drafting device 21, the threads a and b are guided, for example, by stationary thread guides, not shown, so that they maintain their position constantly.
  • a traversing thread guide 22 is provided for guiding the thread c, the traversing region of which lies symmetrically to the center line between the two threads a and b and is approximately twice as large as the distance between the threads a and b.
  • the thread b runs alternately on one side, in the intermediate space and on the other side of the threads a and b in the drafting device 21, as illustrated in FIG. 6.
  • the crimped mixed yarn is cooled on the sieve drum 24 and then intertwined in the interlacing nozzle 25 in order to improve the thread retention.
  • Such interlacing nozzles belong to the prior art; a suitable interlacing nozzle is described for example in GB-PS 924 089.
  • the centerpiece of the traversing thread guide 22 in the exemplary embodiment according to FIGS. 5 and 6 is a piston-cylinder unit, a thread guide eyelet 27 being connected to the piston.
  • the piston-cylinder unit is actuated by a time switch, not shown. Depending on the desired effect, the time intervals between the individual movements can be constant, changed periodically or fluctuate statistically around an average.
