Definitions

  • the invention relates to a method for producing plain yarn according to the preamble of claim 1.
  • US Pat. No. 3,002,804 discloses a method of the type mentioned in the introduction in which a freshly spun thread is drawn through a water bath, then deflected for spraying off the water and stretched as a result of the braking force exerted by the water bath and the deflection.
  • the US-PS also indicates the possibility that part of the yield stress can be applied by a subsequent deflection pin, the deflection pin being used to spray the water. It should be noted that this proportion of the yield stress does not exceed 1/3 may be otherwise the uniformity of the thread will suffer.
  • this object is achieved in a method of the type mentioned at the outset by the characterizing features of claim 1.
  • the filaments coming from the spinning zone are combined as a bundle of threads and passed through a liquid band which is applied to a surface d .
  • the liquid is metered into an overflow surface in such a quantity that the internal absorption capacity of the thread bundle for this liquid is exceeded and the thread also receives a liquid coating on its outer surface.
  • the impregnation lies above the natural internal absorption capacity.
  • the internal absorption capacity is determined in particular by the molecular absorption capacity of the polymer for the liquid and by the absorption capacity based on capillary action between the individual filaments of the thread. With the densest arrangement of the filaments, the absorption capacity between the individual filaments of the thread bundle is already approximately 15% of the filament volume.
  • the amount of liquid supplied is at least 20%, preferably 25 to 35% of the thread weight.
  • the liquid supplied to the liquid band can be heated to a temperature above 501, in particular to a temperature between 701 and 901.
  • the supply of the liquid flow to the thread surface takes place, for. B. through nozzles that open on the surface of an overflow body in an upwardly open channel (see. For example. DE-GM 7605571).
  • the overflow bodies of such nozzles have a length of 30 to 40 mm.
  • the nozzle opens onto the overflow body fairly close to the thread inlet, the liquid on the overflow body is drawn out into a band extending in the thread running direction, which is narrowly limited in the transverse direction to the thread. This narrow limitation is further promoted if the overflow bodies have a thread groove in which the nozzle mouth lies
  • rollers partially wrapped around the thread can also be used for the metered supply of a liquid stream if precautions are taken that the liquid does not pull out into a broad film on such a roller, but rather laterally limited, in a metered amount fed liquid band through which the thread passes.
  • a roller is e.g. B. known from DE-OS 2908404
  • rollers that have thread grooves over their circumference, into which a metered amount of liquid is supplied, are sufficient for the application.
  • the liquid forms a narrow band of liquid through which the thread runs. For this reason, the liquid is not - as in the prior art - provided in a narrow tube, but is applied as a tape to a surface.
  • the thread should not be immersed in a static liquid bath as this does not allow a defined, uniform application of liquid.
  • the application of the liquid as a liquid band on a surface serves on the one hand the purpose of exerting sufficient adhesive forces on the liquid to prevent the liquid from dropping, i.e. H. is torn away by the thread in an uneven form.
  • this adhesion only acts on the liquid band on one side and does not prevent the liquid being "pulled out” from the thread and being pulled off the surface as a continuous band enveloping the thread due to the cohesive forces.
  • All low-viscosity, textile-technically compatible liquids can be used to carry out the invention.
  • a large number of these liquids have water as their main constituent. Pure water can also be used because of its good wetting ability.
  • the water should preferably not with the additions, e.g. B. oils that are usually used for the preparation or finishing of a thread.
  • these additives have a proportion of less than 5%, preferably less than 1% by weight.
  • a wetting agent can be added to promote the wettability of the water.
  • the proportion of the wetting agent in the water is less than 1%, preferably less than 0.5% by weight.
  • the wetting agent contributes in particular to the fact that the thread is soaked uniformly over its entire cross-section.
  • the use of pure water or of water which is provided with a small amount of wetting agents has the particular advantage over other oils, sizes, emulsions and the like which are used in texturing technology the process is reproducible without deviations.
  • Water also has the advantage of low viscosity, especially when heated. For this reason, liquids are preferably used whose viscosity is less than or equal to the viscosity of water or which have water as their main constituents, so that their dynamic properties are decisively determined by the water content.
  • the thread is drawn over a plurality of curved braking surfaces arranged one behind the other in the thread path with a changing direction of curvature.
  • the curvature of the braking surfaces means that the thread can be pulled over the braking surface while exerting a normal force.
  • This normal force counteracts the hydrodynamic buoyancy forces and causes the liquid gap between the braking surface and the thread to remain small.
  • This gap width depends on the shear rate and therefore also the braking force exerted by the liquid on the thread.
  • the radius of curvature is z. B. 10 mm. Radii of less than 10 mm and up to 50 mm have also proven to be satisfactory. Due to the curvature, the normal force of the thread directed onto the braking surface can be limited in such a way that the hydrodynamic forces arising at the respective thread speed ensure the "floating" of the thread, but on the other hand a small gap width of this liquid gap is retained.
  • the normal forces must therefore be so great that the hydrodynamic fluid gap remains so small that a large shear rate arises between the thread running at high speed and the stationary braking surface. It should also be noted that the thread is subjected to centrifugal acceleration when running over the curved braking surface, which tends to be counter to the normal force. On the other hand, the curvature must not be so great that the normal forces created by the tensile forces overcome the hydrodynamic lift of the thread and lead to sliding friction. Even mixed areas between fluid friction and sliding friction are undesirable since the frictional forces are undefined and consequently undefined tensile forces will also exert on the thread.
  • the proposal to arrange several and preferably more than two braking surfaces one behind the other, each of which the thread wraps with less than 1401 and alternating wrap direction, means that the one that emerges from the contact gap between the thread and the braking surface when running over the first braking surface and on the outside liquid in the thread gets into the gap between the thread and this braking surface when running over the next braking surface.
  • an oppositely curved braking surface which projects into the thread course and has a smaller radius of curvature and a shorter running surface between two braking surfaces of equal curvature. This braking surface then serves exclusively to redistribute the applied liquid, while the braking surfaces with a larger radius of curvature and a greater length serve to generate the desired braking force.
  • the braking surfaces are preferably arranged one below the other in the thread run, the deviation of the thread run from the vertical between two braking surfaces being no more than 701 and preferably also no more than 601. It is thereby achieved that liquid that sprays from the thread during the wrapping around the braking surface, splashes in the direction of the next braking surface and therefore gets back to a large extent on the thread path.
  • a series of braking surfaces in a row shows that fluid friction between the thread and braking surfaces can be maintained until the end. This is due to the fact that the wraps are relatively small, so that only relatively small amounts of water spray and the amount of water remaining on the thread is sufficient to cover the surface of the thread and to fill the spaces between the filaments.
  • the previously common dry friction is replaced by hydrodynamic friction in a narrow gap.
  • the thread To achieve fluid friction, the thread must run towards the braking surfaces at a certain minimum speed. This minimum speed is approximately 100 m / min. However, higher speeds are preferred, preferably at least 1800 m / min. If the speed of the thread when it hits the first braking surface is at least 2500 m / min, the thread already gets a higher degree of pre-orientation before it hits the braking surface. This makes the process less sensitive to setting the process parameters.
  • the total length of the braking surface required to exert the stretching force must be determined by experiment. Brake surface lengths of more than 200 mm have proven to be superfluous.
  • the length of the braking surfaces is mainly based on the specified thread speeds in front of and behind the braking surfaces, i. H. adapted to the desired thread tension and stretching
  • the length of the entire braking surface overrun by the thread can be largely adjusted with the loop.
  • the immersion depth is set with which the oppositely curved braking surfaces are immersed in the thread course.
  • the wrap is small according to the invention and is preferably not more than 701, in particular less than 601 on the first and last braking surface and preferably not more than 1401, in particular less than 1201 on the braking surfaces lying between them.
  • the total length of the braking surfaces can also be adjusted in series by a corresponding number of such braking surfaces, which the thread traverses with a changing wrap direction, without any significant space requirement
  • the adjustment of the thread tension between the braking surfaces and the godet unit is essential for the production of a high quality smooth chamois.
  • Quality parameters which correspond to the yarn quality of yarns produced on draw twisting machines can be achieved according to claim 4, by setting the thread tension by adjusting the braking force and the speed of the godet unit between 0.5 and 2 cN / dtex, preferably between 0.7 and 1.5 cN / dtex is set.
  • the braking surfaces can have a running groove to fix the thread running.
  • the braking surfaces may only touch the thread or the liquid layer surrounding it on one side, i. H. not include. Otherwise undefined system conditions arise, with the result that undefined changing braking forces are also exerted on the thread. Therefore, narrow pipes, the z. B. are shown in US-PS 3,002,804, unsuitable as contact surfaces, even if they were curved in the thread running direction, quite apart from the operational disadvantages of such tubes.
  • the temperature of the liquid fed to the thread also makes an important contribution to the production of high-quality threads.
  • the deformation work performed during stretching is converted into heat. Depending on the speed of stretching, this heat leads to a more or less strong temperature increase.
  • the amounts of heat released lead to temperatures that are no longer technologically acceptable.
  • the liquid supplied to the thread before the overflow via the braking surface is heated.
  • the temperature corresponds approximately to the temperature of the glass transition and is above 50 1 C.
  • the heating is particularly effective when the temperature is above 70 1 C, while at 100 1C a limit is set by the evaporation then occurring.
  • the excellent uniformity of the thread quality must be attributed to the fact that the temperature fluctuations of the thread over its cross section and over its length can also be limited in time to a narrow, physically optimal range by the temperature of the liquid. This fluctuation range lies between the current liquid temperature and the evaporation temperature of the liquid.
  • the safety of the method, particularly in the production of threads with textile titanium, is increased if - as is further proposed - the thread coming from the spinneret is still guided through the liquid band while it is hot.
  • the cooling conditions are specified so that the thread temperature is in the range of the glass transition point.
  • the intensity of the air blowing, the length of the air blowing, the distance of the liquid band from the spinneret, and the spin titer of the filaments are particularly important for these cooling conditions. It has been shown that a measure can also be seen here by which the thread break numbers can be drastically reduced and the thread uniformity can be significantly improved.
  • the amount of heat transported by the thread is large enough to heat the amount of liquid applied to the thread very quickly up to the specified temperature range.
  • This temperature range essentially corresponds to the first order glass transition point of the polyesters or polyamides.
  • a further drastic improvement in the thread quality, in particular with regard to its strength and shrinkage properties, is obtained by heating the thread behind the contact surfaces once again, namely in a proven embodiment the conveyor is designed as a heated godet.
  • the godet temperature is regulated to 80 to 160 1C, depending on the polymer.
  • a temperature of approx. 140 1C ⁇ 20 1C has been found to be advantageous for polyesters and approx. 100 1C ⁇ 20 1C for polyamide.
  • the bundle of threads is further provided with a conventional spinning preparation, which in particular consists of water-oil emulsions. This also increases the safety of the process.
  • the liquid is applied as an axially extending, relatively thin film to the individual filaments running side by side.
  • this type of liquid application it is not possible to provide the individual filaments and the bundle of threads with a liquid coating, which lead to hydrodynamic friction on the subsequent brake pins.
  • the invention is based on the new knowledge, which is not predetermined by the state of the art, that by building up a hydrodynamic gap friction in the drawing zone, smooth yarns can be produced which are far superior in quality to the smooth yarns usually produced on drawing machines, even in continuous operation for which the occurrence of fluff is 10: 1 lower than for comparable yarns with the same titer and the same number of filaments, for which the so-called gam uniformity is significantly improved and which are also cheaper because of the lower investment costs and the higher productivity . It is also noteworthy that, on the other hand, there is no wear on the braking surfaces and even grinding marks are not visible.
  • the water application nozzle 6 has a thread channel which is curved both in the direction of the thread running and transversely thereto, in the bottom of which a water supply channel opens.
  • the mouth of the water supply channel is as close as possible to the thread inlet.
  • the radius of curvature of animal curvature in the thread running direction is 40 mm.
  • the radius of curvature across the thread is 10 mm. This curvature ensures that the filaments are combined into a bundle of threads when they reach the area of the confluent water supply channel.
  • the thread is guided behind the water application nozzle 6 over the three parallel, cylindrical braking surfaces 9, 10, 11.
  • the thread between the braking surfaces 9, 10 is guided in a zigzag by the braking surface 11 serving as the deflecting surface.
  • the braking surface 11 can be moved perpendicularly to the yarn path, it can plunge to different depths in the common tagential plane of the braking surfaces 9. As a result, the wrap angle and thus the contact lengths on each braking surface 9 to 11 can be set as desired.
  • the braking surfaces have a radius of curvature of 10 mm.
  • the wrap angle should not be so great for reasons of water balance of the running thread that the thread is deflected by more than 601 from its vertical running direction.
  • the fact that the braking surfaces are arranged vertically one below the other and the deflecting surfaces are only offset from the vertical thread path at a predetermined angle means that water which splashes and drips off is fed back to the thread or the braking or deflecting surfaces.
  • one or more further braking surfaces can be added to extend the braking surfaces.
  • the box 5 has an outlet 18 through which the draining liquid can be collected and possibly returned to the process.
  • the thread coming from the contact surfaces receives its spin finish from the application roller 16 as a preparation before it is drawn off from the heated godet 7.
  • the application of the spin finish can also be done inside the box 5 and z. B. done by an application nozzle which corresponds essentially to the water application nozzle 6.
  • the spin finish can also be applied behind the godet 7. This has the advantage that the thread runs more smoothly on the godet and the surface - especially at temperatures above 1 00 1C - is less contaminated by residues. This makes the process "safer” and improves the uniformity of the thread.
  • the thread is then wound up.
  • the winding spindle is denoted by 13, the bobbin by 14, the traversing device by 12 and the input thread guide from which the thread runs to the traversing device by 15. 17 indicates a so-called tangle nozzle through which the individual filaments are intertwined in individual knots. This has proven to be useful for achieving good bobbins and for improving the further processing of the muftifilament thread, which should not have any twist when carrying out this invention.
  • the winding can be replaced by another type of thread storage, in particular by storing it in cans. Between the godet and the storage further devices for modifying the thread can be arranged such. B. a spun fiber cutter.
  • a polyester thread 90f30 is thus spun, the godet 19 having a take-off speed of 4000 m / min.
  • the thread is first cooled in the cooling shaft and drop shaft 4 to approx. 90 1C.
  • the water application nozzle 6 is supplied with water which is heated to 80 1C. The amount of water is adjusted so that the natural water absorption capacity of the thread is exceeded. The flowing amount of water is 30% of the thread weight.
  • the braking surfaces 9, 10 are run over by adjusting the immersion depth of the deflection surface 11 with a wrap angle of 351, the deflection surface 11 with a wrap angle of 701. As a result, the total overflow length between the thread and braking surfaces is set to approx. 25 mm.
  • This length can be influenced by adjusting the immersion depth.
  • the subsequent godet 19 was heated to 120 1 C.
  • a conventional spin finish was previously applied by roller 16.
  • the winding device was operated in such a way that a coil with a gradual precision winding was created. With precision winding, the traversing speed is reduced proportionally with the spindle speed. The spindle speed decreases because the coil is driven at a constant surface speed. In the case of a step precision winding, however, the traversing speed is again increased from time to time essentially to its initial value. It has been shown to be particularly advantageous that this increase in the traversing speed had a hardly measurable influence on the thread tension in the traversing triangle. In contrast, if the heating of the godet 19 was shadowed, very strong thread tension fluctuations occurred when the traversing speed was increased. The heating of the godet thus proves to be an excellent means of building up bobbins with uniform thread tension and hardness and of maintaining the outstanding properties of the thread obtained by the method according to the invention even when winding up and on the bobbin.
  • the 6 threads then ran over the braking and deflecting surfaces with angles of change on the braking surfaces 9 and 10 of 351 and on the deflecting surface 11 of 701.
  • a stretching tension of 90 cN per thread was set and the threads by godet 7 withdrawn at a speed of 4507 m / min.
  • the godet 7 had a temperature of 145 1C; each thread wrapped around godet and idler 8 times.
  • the roll 1 6 was arranged after the godet 7, through which a customary spin finish was applied to the threads; thereafter the filaments of each thread were swirled in the tangled nozzle 17 and intertwined.
  • the 6 threads were finally wound up separately at a winding speed of 4463 m / min.
  • the polyester threads 76f24 obtained had a strength of 40 cN / tex, an elongation of 22.5%, cooking shrinkage 5.6% and uster (normal) 0.9%. They had 21 swirl points per meter and a fat coverage of 0.72%.
  • the godet 7 had a temperature of 100 1C and pulled the threads at a speed of 3917 m / min, each thread wrapping the godet and the Ilmal idler. The winding took place at a speed of 3799 m / min.
  • the threads 44f10 obtained had a strength of 45 cN / tex, an elongation of 4 0%, boiling water shrinkage of 14.0% and Uster (normal) 0.8%. They had 19 swirl points per meter and 0.78% fat coverage.
