Definitions
- the new invention relates to a method for texturing continuous yarn by means of a texturing nozzle, with a continuous yarn channel into which compressed air with more than 4 bar is blown in the yarn transport direction, the yarn channel at the outlet end being widened with a widening angle greater than 10 °, preferably conically Generation of a supersonic flow.
- the invention further relates to a texturing nozzle for texturing continuous yarn with a continuous yarn channel with an inlet end, a central, preferably cylindrical section with an air injection hole and an outlet end with an expansion angle greater than 10 °.
- texturing is sometimes understood to mean the refinement of spun filament bundles or the corresponding continuous yarns with the aim of giving the yarn a textile character.
- texturing is understood to mean the production of a large number of loops on individual filaments or the production of loop yarn.
- An older solution for texturing is described in EP 0 088 254.
- the continuous filament yarn is fed to the yarn guide channel at the inlet end of a texturing nozzle and textured at a trumpet-shaped outlet end by the forces of a supersonic flow.
- the middle section of the yarn guide channel is cylindrical over the entire length with a constant cross section. The entry is slightly rounded for easy insertion of the untreated yarn.
- EP 0 088 254 was based on a device for texturing at least one continuous yarn consisting of a plurality of filaments with a nozzle loaded with a pressure medium, containing a yarn guide channel and at least one feed for the pressure medium opening into the channel in the radial direction.
- the generic nozzle had an outwardly widening outlet opening of the channel and a spherical or hemispherical guide body projecting into the latter and forming an annular gap with the latter. It was recognized that in the case of textured yarns, maintaining the yarn properties both during the processing process and after it on the finished product is an important criterion for the use of such yarns. Furthermore, the level of the degree of mixing of two or more yarns and the individual filaments of the textured yarns is of essential importance for achieving a uniform product appearance. Stability is used as a concept of quality.
- EP 0 088 254 was based on the task of creating an improved device of the type described, with which an optimal texturing effect can be achieved, which ensures high stability of the yarn and a high degree of mixing of the individual filaments.
- the outer diameter of the convexly curved outlet opening of the channel be at least 4 times the diameter of the channel and at least 0.5 times the diameter of the spherical or hemispherical guide body (5). Production speeds in a range from 100 to over 600 m / min were the optimal results. found. It is interesting to note that the applicant was able to successfully market such nozzles over a period of over 15 years.
- the object of the new invention was now to develop a method and a texturing nozzle which increased performance, in particular up to well over 1000 m / min. allows, but results in the highest yarn quality in as many applications as possible.
- the method according to the invention is characterized in that the compressed air for intensifying the yarn opening is blown into the yarn channel with an injection angle of more than 48 °, in particular more than 50 °.
- the yarn channel has a central, preferably cylindrical section which is transferred into the conical widening in the direction of transport without a jump, the compressed air being blown into the cylindrical section at a sufficient distance from the conically expanded supersonic channel.
- the injection angle as a function of the yarn quality, in particular the yarn titer, in the range from 48 ° to 80 °, preferably 50 ° to 70 °.
- the advantages of the new invention could be used with texturing nozzles with only a single bore through which the compressed air is blown in at an angle greater than 48 ° or 50 °.
- the compressed air is preferably blown into the yarn channel via three bores offset by 120 °. It is crucial in any case that the yarn opening is intensified by blowing the compressed air into the yarn channel, but that knots are avoided in the yarn.
- the texturing nozzle according to the invention is characterized in that the compressed air for intensifying the yarn opening is blown into the yarn channel with an injection angle of more than 48 °, preferably more than 50 °.
- the air injection point is preferably arranged in the cylindrical section at a distance from the conical extension, the distance corresponding at least approximately to the diameter of the yarn channel.
- the new invention brought various insights:
- At least the central, cylindrical section and the conically enlarged outlet section of a texturing nozzle are designed as part of a nozzle core.
- the nozzle core is preferably designed as an insert in a texturing nozzle head and is produced from a material made of wear-resistant material, in particular ceramic.
- the nozzle core is particularly advantageously designed as an exchangeable core, in such a way that a nozzle core with optimal internal dimensions and entry angles can be used. This makes it possible, e.g. to replace an existing nozzle core of the prior art with few manipulations and to use all advantages of the new invention.
- a guide body is arranged at the outlet end of the conically widened section, which can be advanced at least up to close to the conically widened outlet section. This can make a further contribution to the consistency of the quality of the yarn.
- the texturing nozzle is advantageously designed as part of a texturing head, the air distribution being arranged on three air injection bores in the texturing head.
- EP 0 880 61 1 is the basis and starting point for the new invention insofar as it relates to the texturing process step.
- the texturing process is at air speeds in the impact front of Mach 2, e.g. with Mach 2.5 to Mach 5, so intensely that even at the highest yarn throughput speeds, almost all loops are grasped and well integrated into the yarn.
- the generation of an air speed in the high Mach range within the acceleration channel means that the texturing no longer breaks down up to the highest speeds.
- the entire filament composite is routed evenly and directly into the butt front zone within clear outer channel boundaries.
- the actual central criterion for the positive effect of the new invention is that the stability of the yarn is generally improved. If a yarn textured with the new solution is subjected to a great deal of tensile force and released again, it can be determined that the texture, that is to say fixed connection points and loops, remains or remain almost unchanged. This is a crucial factor for the subsequent processing.
- the yarn is drawn in by the accelerating air jet over the corresponding distance, opened further and handed over to the immediately following texturing zone. The blown air jet is then guided to the acceleration channel without being deflected through a discontinuous and strongly widening section.
- One or more yarn threads with the same or different delivery can be introduced and with a production speed of 400 to over 1200 m / min. be textured.
- the compressed air jet in the supersonic duct is accelerated to 2.0 to 6 Mach, preferably to 2.5 to 4 Mach.
- the best results are achieved if the exit-side end of the yarn channel is delimited by an impact body, in such a way that the textured yarn is discharged through a gap approximately at right angles to the yarn channel axis.
- the blowing air is particularly preferably guided from the feed point into a cylindrical section of the yarn channel directly in an axial direction at an approximately constant speed up to the acceleration channel.
- the new solution can also be used to texturize one or more yarn threads with a wide variety of traditions.
- the entire theoretically effective expansion angle of the supersonic duct should be from the smallest to the largest diameter above 10 °, but below 40 °, preferably within 15 ° to 30 °. According to the current roughness values, an upper limit angle (total angle) of 35 ° to 36 ° has resulted in series production. In a conical acceleration duct, the compressed air is accelerated essentially continuously.
- the nozzle channel section immediately upstream of the supersonic channel is preferably approximately cylindrical, with the delivery component being blown into the cylindrical section in the direction of the acceleration channel.
- the pulling force on the yarn is increased with the length of the acceleration channel.
- the expansion of the nozzle or the increase in the Mach number results in the intensity of the texturing.
- the acceleration channel should have at least a cross-sectional expansion range of 1: 2.0, preferably 1: 2.5 or greater. It is further proposed that the length of the acceleration channel is 3 to 15 times, preferably 4 to 12 times larger than the diameter of the yarn channel at the beginning of the acceleration channel.
- the acceleration channel can be completely or partially continuously expanded, have conical sections and / or have a slightly spherical shape.
- the acceleration channel can also be of finely graded design and have different acceleration zones, with at least one zone with high acceleration and at least one zone with low acceleration of the compressed air jet.
- the exit area of the Acceleration channel can also be cylindrical or approximately cylindrical and the entry area can be greatly expanded, but expanded less than 36 °. If the boundary conditions for the acceleration channel were met according to the invention, the variations of the acceleration channel mentioned proved to be almost equivalent or at least equivalent.
- the yarn channel then has a strongly convex, preferably a trumpet-shaped yarn channel mouth that extends by more than 40 ° to the supersonic channel, the transition from the supersonic channel to the yarn channel mouth preferably being discontinuous.
- a decisive factor was found in the fact that the impact conditions in the texturing space can also be positively influenced and kept stable with an impact body.
- a preferred embodiment of the texturing nozzle is characterized in that it has a continuous yarn channel with a central cylindrical section into which the air supply opens, and in the thread running direction a conical acceleration channel directly adjoining the cylindrical section with an opening angle ( ⁇ 2 ) greater than 15 °, and has a subsequent extension section with an opening angle (5) greater than 40 °.

- Figures 10a to 10d the thermal use of a godet heater. Ways and implementation of the invention
- the texturing nozzle 1 has a yarn channel 4 with a cylindrical section 2, which at the same time also corresponds to the narrowest cross section 3 with a diameter d. From the narrowest cross-section 3, the yarn channel 4 merges into an acceleration channel 11 without a cross-sectional jump and is then expanded in a trumpet shape, the trumpet shape being able to be defined with a radius R. Due to the emerging supersonic flow, a corresponding impact front diameter DAE can be determined. Due to the joint front diameter DAE, the detachment or tear-off point Ai, A2, A3 or A4 can be determined relatively precisely. For the effect of the impact front, reference is made to EP 0 880 61 1. The acceleration range of the air can also vary by length. 2 are defined by the location of the narrowest cross section 3 and the tear-off point A. Since it is a real supersonic flow, the air speed can be roughly calculated from this.
- Figure 1 shows a conical configuration of the acceleration channel 1 1, which corresponds to the length l 2 .
- the opening angle ⁇ 2 is specified at 20 °.
- the drainage point A 2 is shown at the end of the supersonic duct, where the yarn duct merges into a discontinuous, strongly conical or trumpet-shaped extension 12 with an opening angle d> 40 °. Due to the geometry, there is a butt front diameter DAE.
- the following relationships result as an example:
- FIG. 2 shows an entire texturing head or nozzle head 20 with a built-in nozzle core 5.
- the unprocessed yarn 21 is fed to the texturing nozzle 1 via a delivery mechanism 22 and transported further as textured yarn 21 ′.
- a baffle 23 is located in the outlet area 13 of the texturing nozzle.
- a compressed air connection P ′ is arranged on the side of the nozzle head 20.
- the textured yarn 21 ' runs at a transport speed VT over a second delivery unit 25.
- the textured yarn 21' is guided over a quality sensor 26, e.g.
- ATQ HemaQuality
- the measurement signals are fed to a computer unit 27.
- the appropriate quality measurement is a prerequisite for optimal production monitoring.
- the values are also an indicator of the yarn quality. In the air blasting texturing process, the quality determination is difficult because there is no defined loop size. It is much easier to determine the deviation from the quality that the customer has found good. This is possible with the ATQ system, since the yarn structure and its deviation can be determined, evaluated and displayed by means of a thread tension sensor 26 and indicated by a single characteristic number, the AT value.
- a thread tension sensor 26 detects in particular the thread tension after the texturing nozzle as an analog electrical signal.
- the AT value is continuously calculated from the mean and variance of the thread tension measured values.
- the size of the AT value depends on the structure of the yarn and is determined by the user according to his own quality requirements. If the thread tension or the variance (uniformity) of the thread tension changes during production, the AT value also changes. Where the upper and lower limit values lie can be determined with yarn mirrors, knitting or fabric samples. They differ depending on the quality requirements.
- the advantage of ATQ measurement is that different types of disruptions from the process are recorded simultaneously, e.g. Equality in texturing, thread wetting, filament breaks, nozzle contamination, impact ball spacing, hotpin temperature, air pressure differences, POY plug-in zone, thread guide, etc.
- FIG. 3 shows a preferred embodiment of an entire nozzle core 5 in cross section in thicker Magnification shows.
- the outer fitting shape is preferably adapted exactly to the nozzle cores of the prior art. This applies above all to the critical installation dimensions, the bore diameter BD, the total length L, the nozzle head height KH and the distance LA for the compressed air connections PP '. The tests have shown that the optimal injection angle ß must be greater than 48 °.
- the distance X of the corresponding compressed air holes 15 is critical with respect to the acceleration channel.
- the yarn channel 4 has in the inlet area of the yarn, arrow 1 6, a yarn insertion cone 6. The backward exhaust air flow is reduced by the compressed air directed in the yarn transport direction via the oblique compressed air bores 15.
- the dimension “X” indicates that the air hole is preferably set back from the narrowest cross section 3 at least approximately by the size of the diameter d.
- the texturing nozzle 1 or the nozzle core 5 has a yarn insertion cone 6, a cylindrical central section 7, a cone 8, which at the same time corresponds to the acceleration channel 11, and an expanded texturing space 9.
- the texturing space becomes transverse to Flow limited by a trumpet shape 1 2, which can also be designed as an open conical funnel.
- FIG. 3 shows a texturing nozzle with three compressed air bores 1, which are offset by 120 ° and open into the yarn channel 4 at the same point Sm.
- the new nozzle core 5 can be designed as an exchange core for the previous state of the art.
- the dimensions B d , E L as the installation length, L A + K H and K H are therefore preferably not only produced in the same way, but also with the same tolerances.
- the trumpet shape in the outer exit area is also preferably produced in the same way as in the prior art, with a corresponding radius R.
- the impact body 14 can have any shape: spherical, spherically flat or even in the form of a spherical cap. The exact position of the impact body 14 in the exit area is maintained by maintaining the outer mass, corresponding to an equal withdrawal gap S pl .
- the texturing space 18 remains unchanged on the outside, but is directed backwards and is defined by the acceleration channel 11.
- the texturing space can also be enlarged into the acceleration channel depending on the level of the selected air pressure.
- the nozzle core 5 is produced from a high-quality material, such as ceramic, hard metal or special steel, and is actually the expensive part of a texturing nozzle. It is important with the new nozzle that the cylindrical wall surface 21 and the wall surface 22 are the highest in the area of the acceleration channel Goodness has. The nature of the trumpet extension is determined with regard to the yarn friction.
- FIG. 5 shows an entire nozzle head 20 with a nozzle core 5 and an impact body 14, which is anchored in a known housing 28 in an adjustable manner via an arm 27.
- the impact body 14 with the arm 27 is pulled or pivoted away in a known manner according to arrow 29 from the working area 30 of the texturing nozzle.
- the compressed air is supplied from a housing chamber 31 via the compressed air bores.
- the nozzle core 5 is clamped to the housing 33 via a clamping bracket 32.
- the impact body can also have a spherical shape.
- FIG. 6 shows the texturing of the prior art according to EP 0 088 254 in a purely schematic manner at the bottom left. Two main parameters are emphasized. An opening zone Oe-Zi and a butt front diameter DAs, starting from a diameter d, corresponding to a nozzle, as described in EP 0 088 254. In contrast, the texturing according to EP 0 880 61 1 is shown at the top right. It is clearly recognizable that the values Oe-Z2 and DAE are larger. The yarn opening zone Oe-Z2 begins shortly before the acceleration channel in the area of the compressed air supply P and is already significantly larger in relation to the relatively short yarn opening zone Oe-Zi of the solution according to EP 0 088 254.
- the essential statement in FIG. 6 lies in the diagrammatic comparison of the yarn tension according to the prior art (curve T 31 1) with Mach ⁇ 2 and a texturing nozzle according to the invention (curve S 31 5) with Mach> 2 and the new nozzle.
- the thread tension is in CN.
- the production speed is Pgeschw. in m / min. shown.
- Curve T 31 1 allows the yarn tension to collapse significantly over a production speed of 500 m / min. detect. Above about 650 m / min. the texturing broke down with the nozzle according to EP 0 088 254.
- curve S 315 with the corresponding nozzle from EP 0 880 61 1 shows that the yarn tension is not only much higher, but in the range from 400 to 700 m / min. is almost constant and only drops slowly in higher production areas.
- Increasing the Mach number is one of the most important parameters for intensifying the texturing.
- the increase in the injection angle is one of the most important parameters for the quality of the texturing, as shown with the new nozzle as the third example at the top left.
- the injection angle with the range from 50 ° to 60 ° is given as an example.
- the yarn opening zone Oe-Z3 is larger than in the solution on the top right (according to EP 0 880 61 1) and significantly larger than in the solution on the bottom left (according to EP 0 088 254).
- the surprisingly positive effect lies in the first section of the yarn opening zone, such as OZi and OZ2 or as marked in the corresponding circle.
- the outer difference lies only in the change in the injection angle.
- the striking increase in thread tension begins at an angle of over 48 ° and can only be understood with a combinatorial effect.
- 48 ° injection angle means a threshold, but this only applies to texturing nozzles according to EP 0 880 61 1. This type of texture nozzle has a sufficient performance reserve so that even a slight intensification of the yarn opening is converted into an increase in the yarn quality.
- FIGS. 7a to 7c and 8a to 8c show diagrammatically the relationships of various parameters with respect to the prior art (T341 K1 and S345) and the texturing nozzles according to the invention with blowing angles from 50 ° to 58 °.
- the thread tension increases remarkably from left to right from about 20 CN to 56 cN.
- the thread tension is more than doubled on average with the new invention.
- FIG. 7a initially shows a somewhat less steep increase in the thread tension. So far, all tests have given variations in the context of the two diagrams 7a and 8a and thus the new finding that the thread tension is markedly higher above an injection angle of 48 °.
- FIG. 7c and FIG. 8c each represent three different textured yarn patterns.
- the upper yarn patterns were produced with nozzles of the prior art, at the top according to EP 0 088 254 (T-nozzle) and in the middle according to EP 0 880 61 1 ( S nozzle).
- the lowest patterns were created with texturing nozzles according to the new invention.
- the dimensions B1 and B2 indicate the distance size for the most protruding slings.
- the dimension B3 is significantly smaller. In particular, very compact places and still relatively dense places with many loops can be seen at short intervals. The crucial point now is that the yarn patterns behave very differently under load.
- FIG. 9 shows a schematic overview in relation to the new texturing process.
- the separate process stages are progressively shown from top to bottom.
- Smooth yarn 100 is fed from above via a first delivery unit LW1 at a given transport speed V1 to a texturing nozzle 101 and through the yarn channel 104.
- Highly compressed, preferably not heated, air is blown into the yarn channel 104 at an angle ⁇ in the transport direction of the yarn via compressed air channels 103, which are connected to a compressed air source oil.
- the yarn channel 104 is opened conically in such a way that a strongly accelerated air flow with supersonic, preferably with more than Mach 2, occurs in the conical section 102.
- the shock waves generate the actual texturing, as is described in detail in WO97 / 30200 mentioned at the beginning.
- the first section from the air injection point 105 into the yarn channel 104 to the first section of the conical extension 102 serves to loosen and open the plain yarn so that the individual filaments are exposed to the sonic flow.
- the texturing takes place either within the conical part 102 or in the outlet area.
- Mach number There is a direct proportionality between Mach number and texturing. The higher the Mach number, the stronger the impact and the more intense the texturing.
- G.mech . Yarn treatment with the mechanical effect of a compressed air flow (supersonic flow). Th. After .: thermal aftertreatment with hot steam (possibly only heat or hot air). D: steam. PL: compressed air.
- the production speed could reach up to 1,500 m / min. can be increased without breakdown of the texturing and without slagging, the limit being given by the existing test facility.
- the best texturing qualities were possible at production speeds of well over 800 m / min. be achieved.
- the discovered parameters lie on the one hand in a heat treatment upstream and / or downstream of the texturing, and on the other hand in an increase in the Mach number by increasing the air pressure and correspondingly designing the acceleration channel.
- An expert assesses an important quality criterion in texturing on the basis of the thread tension of the yarn emerging from the texturing nozzle, which is also recognized as a measure of the intensity of the texturing.
- the yarn tension is established on the textured yarn 106 between the texturing nozzle (TD) and a delivery unit LW2.
- thermal treatment has now been carried out on the yarn under tension.
- the yarn was heated to approx. 180 ° C.
- Initial attempts have already been successfully completed with a hot pin or with heated godets as well as with a hot plate (contactless), with the surprising result that the quality limit in terms of transport speed could be massively increased. It is currently assumed that the thermal post-treatment described has a fixing and at the same time a shrinking effect on the textured yarn and thus supports the texturing.
- thermal pretreatment also has a positive effect on the texturing process.
- a combinatorial effect between shrinkage and yarn opening in the section between the air injection point in the yarn channel and the first section of the conical widening in the area of the supersonic speed should be the cause of the success here.
- the stiffness is reduced by warming up the yarn, so that the prerequisite for loop formation in the texturing process is improved.
- tests with both hotplate and hotpin as heat sources were successfully completed. It may also help that the thermal pretreatment of the yarn avoids a negative cooling effect due to the air expansion in the texturing nozzle and therefore the texturing of the heated yarn can be improved. With the very high transport speed, part of the heat in the yarn itself is retained up to the area of the loop formation.
- FIG. 9 shows the action by a processing medium, whether it is carried out by hot air, superheated steam or another hot gas on the running yarn shortly or immediately one after the other.
- the procedural interventions are not isolated in this way, but are combined in a joint venture between two suppliers. This means that the yarn is only held at the beginning and at the end, both mechanical air intervention and thermal intervention take place in between.
- the thermal treatment is carried out on the tension in the filaments or in the yarn, which is still mechanically generated by the compressed air.
- FIGS. 10a to 10d show examples of a locally separated mechanical and thermal action.
- the thermal effect is spatially before or after the actual texturing.
- the yarn heating can be used positively for texturing, albeit to a lesser extent.
- FIGS. 10a to 10d show the use of the so-called heated and driven godets for the thermal treatment with some important possible uses.
- the temperature in the godet shows whether it is a heated position.
- a hotplate or a continuous steam chamber according to the invention can also be used in all representations.
