Definitions

  • the invention relates to a method for producing air-textured Threads from at least one upright thread and at least an effect thread in which at least the upright thread is drawn before using a Texturing unit is supplied and in which the textured, yarn consisting of stand and effect thread is heated.
  • Such methods take advantage of the effect that during the heating of the after the texturing unit textured yarn of the upright thread stretched before texturing shrinks less than the effect thread. This has the consequence that in the texturing formed by the effect thread Loops contracted during said heating be, which ultimately makes the thread more desirable Way gets a relatively smooth surface.
  • An object of the invention is the method of continue to develop in such a way that also thin, very fine threads with sufficient strength are producible.
  • this object is achieved in that a Upright thread with a fineness between 80 and 200 dtex and an effect thread with a fineness between 60 and 165 dtex is used, the effect thread is finer than the upright thread.
  • Threads is, for example, between 11 and 12%, i.e. the length of the textured thread can be stretched by 11 to 12% be without tearing.
  • the method according to the invention therefore makes them very fine Threads producible that are both high strength as well a high level of uniformity with a high degree of freedom from errors exhibit.
  • a stand thread with a fineness between 140 and 160 dtex and / or an effect thread with a Fineness between 70 and 90 dtex is used.
  • Rise Around / or Effect threads can have between 36 and 144 filaments each exhibit.
  • the upright thread is in front of the Texturing unit by 1.8 to 2.6 times, in particular by stretched 2 to 2.4 times. Furthermore, it is from Advantage if, in addition to the upright thread, the effect thread is stretched in front of the texturing unit, the stretching of the effect thread is preferably smaller than the stretching of the thread.
  • the effect thread can, for example 1.5 to 1.9 times, in particular 1.6 to Be stretched 1.8 times.
  • the upright thread can be heated more than the effect thread, with temperatures regarding the heating of the standing thread between 150 ° and 240 °, in particular between 160 ° and offer 220 °.
  • Temperatures between 100 ° C and 200 ° C, in particular between 140 ° C and 180 ° C makes sense.
  • the upright and / or the effect thread in front of the texturing unit each over two successive godets be performed.
  • the drawing of upright and / or effect thread can then, for example, by different drive speeds two successive godets are effected, the rear godet in the direction of the conveyor runs faster than the front godet.
  • a stretching can also be carried out by means of the godets Heating of upright and / or effect threads are effected, by at least one of the upright and / or effect threads assigned godets is heated.
  • the Godets to the temperatures already mentioned above be heated.
  • the threads can each between 5 and 20 times, in particular between 6 and 10 times helically around a godet, so that the frictional forces between godets and threads are sufficient are high.
  • this stretching can, for example, by a factor between 0.95 and 1.1, in particular between 1.01 and 1.05.
  • the stretching is preferably carried out in such a way that the distance of the textured yarn that is currently heating is also post-stretched at the same time. This can prevent that the textured yarn during overall heating contracts too much.
  • Concrete is achieved by a post-stretching factor greater than 1, that the main thread component of the textured yarn during of the heating process is stretched. With a post-stretch factor less than 1 ensures that the upright component maximum by the post-stretching factor can shrink.
  • the shrinkage of the upright component of the textured Yarn is thus limited by the post-stretching mentioned, and the loops formed by the effect thread can decrease in size in the desired manner due to the heating or contract.
  • the heating of the textured yarn after the texturing unit is preferably carried out such that the temperature of the textured yarn in the range between 200 ° C and 300 ° C, in particular between 210 ° C and 260 ° C.
  • this can textured yarn the texturing unit at a speed between 300 m / min and 500 m / min, especially at 400 leave m / min.
  • both effect thread and upright thread are delivered at a speed which is about the speed at which the textured yarn Texturing unit leaves.
  • the delivery speed of the standing thread is preferred between 4% and 8%, especially about 6% above speed, with which the textured yarn the texturing unit leaves.
  • the speed of delivery of the effect thread is preferred between 14% and 20%, in particular between 16% and 18% over the speed at which the textured yarn Texturing unit leaves.
  • the texturing unit which is preferably designed as a texturing nozzle with a pressure between 6 and operated at 14 bar.
  • the water throughput for example between 0.1 l / h and 1 l / h, in particular can be approximately 0.25 l / h.
  • the thread can be normal, for example Drinking water can be used, which previously had an activated carbon filter happens.
  • Standard and / or effect thread can be made of polyester, polyamide, Polyamide 6, polyamide 6.6, polyamide 4.6, polyethylene and / or Made of viscose.
  • the texturing unit instead of using only one standing and one It is alternatively possible to effect threads, the texturing unit one stand and two effect threads or two stand and one Feed effect thread or two upright and effect threads.
  • the textured yarn can in particular produce sewing thread be twisted after being heated.
  • the twist is, for example, between 150 and 600, in particular between 300 and 500 turns per meter.
  • the standing thread 1 is used during the operation of the device subtracted from a supply spool 2. In an analogous way the effect thread 3 is drawn off from a second supply spool 4.
  • the upright thread arrives at a first one Galette 5, from the upright thread 1 several times helically is entwined.
  • the upright thread 1 is a second Galette 6 excited, which he also wraps around several times.
  • the effect thread 3 is in an analogous manner via a third godet 7 and a fourth godet 8 performed.
  • the upright thread 1 arrives to a wetting station 9 where he wets with water becomes.
  • the textured yarn 11 leaving the texturing nozzle becomes fed to a heating device 13 via a fifth godet 12, from where the heated textured yarn 11 to one sixth godet 14 arrives.
  • the godets 12 and 14 are of the textured yarn 11 in turn entwined several times.
  • the textured yarn becomes one Rewinder 15 fed.
  • the described device can, for example, in the following Mode operated, the sizes mentioned, of course can be varied in the above-mentioned areas:
  • the upright thread 1 is removed from the supply bobbin 2 at one speed deducted from about 240 m / min and the first Galette 5 fed. In a corresponding way, the effect thread 3 at a speed of approximately 310 m / min from deducted the supply spool 4 and fed to the third godet 7.
  • the upright thread has a fineness of approximately 160 dtex, while the effect thread has a fineness of approximately 90 dtex owns.
  • the second godet 6 runs faster by a factor of 1.8 than the first godet 5, which results in a corresponding stretching of the thread 1 results.
  • the fourth godet 8 runs faster by a factor of 1.5 than the third godet 7, with a corresponding one also here Stretching of the effect thread 2 results.
  • the second godet 6 is heated to a temperature of 240 ° C. so that a corresponding heating of the standing thread 1 is effected.
  • the fourth godet is similar 8 for heating the effect thread to a temperature of 200 ° C designed.
  • the first godet 5 and the third godet 7 both are not heated.
  • the stretched and heated is in the wetting station 9 Standard thread wetted with water, with a water throughput here of 0.7 l / h comes into play.
  • the texturing nozzle 10 is at an air pressure of approximately 7 operated bar.
  • the intermingled and textured yarn 11 is between the fifth godet 12 and sixth godet 14 by a factor of 1.01, which is caused by the fact that the sixth godet 14 faster by a corresponding factor runs as the fifth godet 12.
  • the textured yarn 11 leaves the texturing nozzle 10 with a Speed of about 400 m / min and is dependent on that Rewinder 15 added at approximately the same speed.
