Description

200422451 发明 Description of the invention: [Technical field to which the invention belongs] / The present invention relates to a method of using a winding nozzle to roll up the endless yarn I. 'The Haihai winding nozzle has a through yarn channel.' Compressed air is blown into the yarn channel with a pressure of more than 4 bar in the yarn conveying direction, where the exit π end of the yarn channel is greater than 1G. The expansion angle (and should be tapered) of Yikuan is also about a kind of winding nozzle for winding endless yarn, which has a through yarn channel, which has an inlet end, a middle section ( It should be cylindrical 'and have -air blowing holes), and-the exit section, the Dhai outlet σρ slave is conical, and its expansion angle is greater than i 〇. , But less than 40. . [Prior art] The term "TextUreren" still refers to the spinning of filaments or related endless yarns (Veredeiung), the purpose of which is to give the yarn a textile characteristic. In the following description, the term "association" refers to the generation of a plurality of loops (ScMingen, English: 100p) on individual filament yarns or the formation of loop yarns (Schlingengarn). An older solution is found in European patent Ep 0088 254. The endless filament yarn is fed to the yarn guide channel at the population end of a winding nozzle, and is wound at the K-shaped exit end by the force of a supersonic flow. The middle section of the yarn guide channel is cylindrical in its entire length and has a constant cross section. The entrance is slightly rounded, so that the unprocessed yarn is introduced i + l? Ill X -b λί, / ^ Π ^. At the horn-shaped exit end, there is a lead conductor ', in which a loop (loop) is formed between the horn-shaped portion and the guide body. The yarn is fed to the winding nozzle in a large overfeed amount. On each individual long yarn 200422451

In the ring, this super-feed system, must, two I

Titer). And ... the fineness transmitted at the exit end (^ European patent EP0⑽254 is an endless yarn composed of a kind of winding device ^ ^ is wound with a nozzle for exhausting medium, which contains a " supply pipe for pressure medium, Along the 彳, t 丨 common phase and at least one,, ，, mouth opening into the channel. The exit opening of such noise-spraying channel widens outward, ^, bad or spherical guide 髀, dog Extend into the opening of the exit, the toilet body and the dagger form an annular gap. It is known that in the case of winding a yarn, after the processing process time, 'the nature of the yarn must be obtained' This is important for the availability of the final product yarn In addition, the degree of mixing of two or more yarns, and the degree of mixing of the individual filaments of the winding yarn are important to achieve the fabric texture (Uarenbild). Here, the set Keji ^ 疋 & is used for the quality index of the work. To determine the instability of the yarn, the yarn strip (with four windings, each with a perimeter of one meter) is on a hinge plate. On the formation, as shown-a kind of fineness 8dtex poly cool multifilament yarn. This gauze band is subjected to a load for a period of minutes, and then the length X is measured. Then, "the same load of 125 cN is applied for one minute, and after the load is released", the load is re-applied to the load after-minutes, and the length Y is measured in a minute / minute. In this way, the value of the instability J: 100% is obtained. This instability indicates how much% of the residual stretching will be caused by the amount of green $ #., ≫ added. The purpose of Ε 0 0 088 254 is M, and the purpose of the purpose is to provide one of the above-mentioned types of reform 200422451 J. The best and the best effect is to ensure the yarn has a high stability and make individual long-lasting ancient times. Degree of directional cooperation. The solution is to make the outer diameter of the convex raised exit opening of the channel at least equal to 4 times the diameter of the channel: and at least equal to 0.5 times the diameter of the spherical or hemispherical guide (5). The best results were found at production speeds in the range of 100 to more than _m / min. It is worth noting the fact that the applicant successfully marketed the related Harbin + / / t over a period of more than 15 years. The quality of the yarn produced in this way has been proven to be very good over the years, but the quality of the products that hope to improve efficiency is increasing; Zhang, Tai, J. The application of the solution in EP 0880 61 1 ' Increase efficiency to more than 100. M / min. The central idea of efficiency improvement is to make the airflow properties denser in this widened supersonic channel, in other words, = ί ΐ Γ Γ ::: 中 作 ”r The special measurement standard is based on the ϋ 088 254 scheme 'Yarn tension About _ minutes. Yarn conveying speed: greatly reduced. This finally explains the limit of the power of this nozzle type. It has a way to dense the air flow in the supersonic channel to 254 to make the yarn sheet 880 to ^, making the material The speed is increased by 42%. The quality of the yarn processed in this way is still the same, even better. However, the practical weight is unexpected because of the demand in many applications. The objective of Beikou p without paying is to provide a method and a scrolling ... can improve the efficiency, the surnames such as H, Tai, and D are over 1,000 m / min, but they are still as good as possible The purpose of the dagger is the highest yarn quality. 200422451 [Explanation of the invention] The method according to the present invention is characterized in that the compressed air for intensifying the yarn opening effect is greater than 48 ° (especially greater than 50). ) Into the yarn channel • For the best air blowing angle, the data obtained by EP 088 254's winding nozzle is at 48. . More than 48. Only makes the volume worse. Regarding this black, you can also refer to A · Demir in February 1990 (Vol · 112/97) ^

"Journal of Engineerin for for industry" research masterpiece. The author of this topic is expected to study a series of important parameters. Here use the nozzle test with 30., 45. and 60. Blow-in angle. See in all aspects. ^ 60 The nozzle with an under-entry angle is worse, because at 60. The amount of time is therefore t: The development of the nozzle of the winding nozzle is the empirical conclusion. ST is right: :: doubt, in the newer nozzle category of "61" Second, that is, blowing two: Γ follows this kind of experience that has been confirmed over many years. The scope is the best, and this specificity is still adopted on the angle of E " But just blow. Complete: Two T yarn feeders, A ... Dou also, we found that ‘Using EP 〇 880 611: Increasing the angle of entry, the second congratulation in the first series: The quality has been unexpectedly improved. As a result, the two rolls of yarn in the hair 圪 two program areas know 73 people know a little bit, the opening operation of the banknote winding operation 200422451 must be optimally coordinated with each other. A &. ° Repeated tests have shown that ... In the solution of EP 0 088 254, the restriction is located in this winding area, so increasing the yarn opening effect will only lead to unfavorable results. Cut entanglement

In the field of Verwirbelung, entangling), it is known that when the blowing angle is 90 °, the yarn opening effect is competitive. The purpose of entanglement is to form regular knots in the yarn. An example of entanglement can be found in DE i95 8019. On the other hand, in the case of winding the yarn, no knot is formed. For these two fundamentally different methods of forming a knot and forming a loop, the blow-in angle must be set-the limit range. However: "May determine this boundary. So far, the blowing angle has been in the range of 0. , And especially 50. ~ About 7. The upper limit still cannot be calculated accurately. The yarn passage has a central section, which should be cylindrical. It has “the tapered widening part, without any sudden enlargement during it: ground ^ Xuanxuan pressure air is far enough away from the tapered widened supersonic channel #ground, blow In terms of cutting edge research, three new cognitions were mainly provided: § 0 880 661's densely interspersed, and occasional, if the blowing angle is increased beyond the quality of the winding nozzle can make the quality When the fineness of various yarns is increased by more than 48. m, the quality starts to improve significantly. 65.) ": At 52. B temple (―partially reached 60., or even 65), the yarn quality remained surprisingly constant. . But even yarn fineness is the most related. The angle of entry of native people is also related to it. Therefore, I propose that the blowing angle be determined to be especially (and especially * 50. 200422451 degree function. The advantages of the present invention can be used in a winding nozzle with only a single hole (compressed air is blown in through the hole at an angle greater than 48 ° or 50 °), but the compressed air is taken through three The holes separated by 120 ° are blown into the yarn L ^-in any case, heavy The reason is that the yarn opening effect is intensified by the compressed air blowing into the yarn channel, but the formation of knots in the yarn can be avoided. The winding nozzle of the present invention is characterized in that the compressed air used to intensify the yarn opening effect is larger than 48. (and preferably greater than 50.) The blowing angle is blown into the y, y channels. It is best that the air blowing position is set in this cylindrical section at a distance from the tapered widened section, The distance is at least approximately equal to the diameter of the yarn channel. Based on the current knowledge, this: the length of the one program stage—the yarn opening and winding stage, which is too short in the nozzle of the previous Ep 0088 254. This is also one of the reasons for using these old solutions to limit their speed of transportation. &Amp; The present invention opens up different cognitions: self-optimization; then their ground 1. Opening operations and winding operations of yarns Must be separately 2. The two completely different functions should be optimized separately. The implementation should be implemented so that the yarn operation process of the yarn opening operation is completed immediately at the end of the yarn operation. 3. However, it is necessary to follow each other closely. Do the scrolling, or At least one central nozzle section of the coiling nozzle is designed as a nozzle core and is inserted into a coiling nozzle head (ceramic)). The cylindrical section and cone Deformed wide out part. This nozzle core should be designed to be medium, and wear-resistant material (particularly 200422451 is particularly advantageous. Replace the nozzle core ^ V, I ":, so that one has the best Internal dimensions and inlet angle of the nozzle core: annual income. Therefore, for example and t, one can use an existing nozzle core in the conventional technology with very few working lines 'and take advantage of all the advantages of the present invention: as in the conventional technology' A V-limb is provided at the exit end of the tapered widened section, which can reach at least the exit section attachment at least. Such as daggers further promote constant yarn quality.搽 葩 From then on, the scroll-enrolling mouth should be designed as a part of the scroll-enrolling member. The air distribution π 70 仵 5 is in the three empty holes of the scroll-enrolling master. For details, please refer to Ερ 〇88〇 月 月The basis of the hand (if the program phase is about winding). In ep 〇880 611 to 1 丨, the key of Chu ηααν Mody ^ One of the key is that after the winding nozzle nozzle θ, ° only increase the yarn tension Only in this way can the quality be improved. This breakthrough can be achieved only when the blown air f to the Mach 2 range. Many research series not only improve the quality, but also increase the quality of the production process: "Singularly few. The Mach number has only slightly increased. Super㉟2 has obvious knots and squares. The best phenomenon of the intensification of the phase of the contracting process can be seen: in the "Heng Xin ^ Wu 枰 j by the impact front" (st. SSf〇ront) The speed difference σ y directly before and after directly affects the relevant clips that air clamps to the filament directly. In the area of the impact front, the strength is increased, which makes the noise and the force increase. n If the Mach number is increased, the situation

Alas. In accordance with the present invention, the following laws are known: higher Mach number = stronger = more intensive association work I ^ ^ 棬. Ritualized supersonic flow creates a wider front and makes the yarn open.

,, ′, And 糸 are more divergent, so there will be no loops that deviate sideways beyond the area of impact # I 0. Since the production of the supersonic 12-speed current in the acceleration channel hurts its m ”soil and take length, we use a higher Mach number range 'for example, without Mach 1 5 and Tian κ. Using Mach 2.5 can also make The effective exit cross-section is similar or nearly g times. There are a variety of unexpected observations in the Shizuli area, and it is consistent with the present invention. Viewpoint: ._ Θ When using supersonic channels designed for the Mach range, the quality of the wood is improved at the same production speed compared with the previous sales technology. The test research has been carried out until the production speed is reduced to ~ 1500 meters / knife 'without disintegrating the winding effect (~ sa bile and zipper). It is immediately measured on the measurement technology. The average yarn tension has risen to nearly 50%. In addition, in a large speed range, such as 400 ~ 700 m / min, this increase remains almost constant. It is also true that even when the k of the compressed air supply pressure is selected There is also a major influencing factor. In order to ensure a high Mach number, In many cases, a higher supply pressure is required. This pressure is approximately between 6 and 14 bar, but can be raised to 20 bar or higher. Comparison of the prior art according to the European Patent EP 0 088 254 Research and novel solutions in the category of EP 0 080 66 1 yield the following laws in another significant range ... At higher production speeds, the quality of the winding volume is lower than when using one at lower production speeds The supersonic channel designed by the Mach range has a contracting quality of at least the same or better. The contracting process is dense when the air velocity in the impact front exceeds Mach 2 (for example, at Mach 2.5 to Mach 5), so that even Even at the highest yarn passing speed, 13 200422451 holds all the loops almost without exception and is perfectly integrated in the yarn. The high Mach range air speed in the acceleration channel can be used-until the highest It will not disintegrate up to the speed. Secondly, the entire filament composite yarn is guided in within a clear outer feed limit and directly hits the original center base of the impact front area b on the positive effect of the present invention. The reason is that the stability of the yarn is generally improved. If a yarn wound with this novel solution is subjected to a strong tensile stress and then relaxed, it can be confirmed whether the structure i (TeXtur), that is, the combination position and the loop Can still remain almost unchanged. This is a decisive factor for the following processing. In the acceleration channel, the yarn is accelerated by the accelerated air jet in the relevant path ^ 方 拉 人 ， # 开 纱 'and sent Into the winding area immediately following. The blowing air flow is not diverted after the acceleration channel, and is guided through a discontinuously widening and rapidly widening section. One or more yarns can be used in the same way Or feed it in different overfeed amounts, and use the production speed of 400 ~ 12000m / min to do the winding. 5〜4 马赫。 Compressed air jet accelerated in the supersonic channel to 2〇 ~ 6 = Hz 'and preferably to 2. 5 ~ 4 Mach. The best result is achieved if the exit of the yarn channel σ end uses an anti-elastic body to limit the J 使得 to make the winding yarn approximately perpendicular to the yarn channel from the warp-gap. A particularly preferred method is to send the blowing air in the novel invention in accordance with the principle of radiation (Radialprinzip) from the i to the position of a cylindrical section of the yarn channel, and send it directly along an axis at a constant speed. Until the acceleration channel. As in the prior art 0 880 61 1, this novel solution can also be used to wind one or several yarns at different overfeeds. The theoretically effective widening angle of the σ-speed channel is from the smallest to the largest 14 200422451 with a diameter of more than 10. , But less than 40. , And should be at 15. ~ 3〇. Between. According to the current general roughness value, the maximum angle (total angle) for series manufacturing is 35. ~ 36. In a conical acceleration channel, the compressed air accelerates approximately constant. The nozzle passage section directly in front of the supersonic passage should preferably be designed in a substantially cylindrical shape, wherein the cylindrical section is blown into the acceleration passage by a conveying element. The pull-in force acting on the yarn increases with the length of the acceleration channel. The variable nozzle width or increased Mach number makes the winding effect dense. The widening range of the cross section of the acceleration channel should be at least le20, and preferably ^, 2.5 or more. In addition, the length of the acceleration channel is 3 to 15 # larger than the diameter of the yarn channel at the beginning of the acceleration channel, and preferably 4 to 12 times. The acceleration channel may be designed to be continuously widened, in whole or in part, with tapered sections, and / or slightly spherical. However, the acceleration channel can also be designed as a subdivision mode, which has different acceleration regions with at least one larger acceleration of the compressed air flow: the region and at least one region with less acceleration. In this way, the exit area of the acceleration channel can be designed to be cylindrical or nearly cylindrically raised [while the entrance area is rapidly widening, but with a small force36. The angle becomes wider. If the edge and image conditions of the acceleration channel are maintained in accordance with the present invention, the changes in the above-mentioned acceleration channel show almost equal or at least phase. The yarn channel behind the supersonic channel has an apparent & widened yarn channel opening, and should be shaped like 4q.胄 Wide, Lizhong, the transition area from the supersonic Ϊ channel to the yarn channel opening should extend non-continuously: Decisive: The factor is: the use-rebound body can also positively affect the Pressure properties, — and keep% 疋. A preferred design of the winding nozzle is characterized by: a through yarn passage of the section, 1 for the warehouse, and the central cylindrical part of the lice supply f is opened into the section, and has a different running direction along the line 15 Opening Angle and Opening Angle The present invention-tapered acceleration channel is directly connected to the cylindrical section, (α 2) is greater than 15 °, and there is a subsequent widening section, (3) is greater than 40 °. Paper with some examples to explain further details. [Performance method] Please refer to Figure 1 of the painting, the winding nozzle (1) has a yarn pass with a cylindrical portion (2) ^ "

Face (3) is U) 'This section is also the narrowest cross section with diameter d, and the narrowest cross section (3) of this section gradually transitions to the one plus channel (11), 苴In ancient times, there was no sudden change after the eighth summer, and then it widened in a trumpet shape. However, the Lakou octagon can be defined by the field radius R. According to the adjusted supersonic flow moon, take out the relevant "species ^ I green _, run engine front diameter" DAE. According to the diameter of the impact front, the vehicle can accurately determine the release position or tear-off position A. The effect of the impact front can be referred to EP 0 880 61 1. The acceleration area of the air ^ uses the position of the cross section ⑺ ... 2 and the tear-off position Α | | Fang, k 疋 a true supersonic flow, so it can be approximately calculated from this

Gas speed. Figure 1 shows the tapered design of the acceleration channel (11), which has a length of ". The opening angle is again 20". The release position A2 is shown at the end of the supersonic channel, where the yarn channel is at an opening angle δ > 4 〇. Transition to a steeply enlarged conical or trumpet widened portion (12) with a non-constant taper. Due to this geometry-a kind of impact front diameter '. For example, there is about the following relationship: L2 / d = 4. 2 16 200422451 330m / s (Mach i) ΆΕ '2 · 5— Mde = Mach 3 · Extending the velocity channel at the relevant opening angle can increase the diameter of the impact front. It is in the area where the impact front is formed Generates the "compressive shock front" (13) as large as possible, which has a region of sudden pressure increase (〗 4). The original winding effect occurred in the area of the "repetitive shrinkage front" (〗 3). The air moving speed was about 50 times faster than the yarn. It can be known from many experiments that the loosening positions A3 and A4 can also be migrated into the acceleration channel (11), especially when the supply pressure drops. It is practical and can be obtained for various yarns. The most suitable supply pressure, in which the length of the acceleration channel is designed by the designer in consideration of the most unfavorable conditions, that is, it is selected to be longer. ^ Indicates the centerline of the "blowing hole" (15), 'indicates the centerline of the yarn channel ⑷ :: The intersection of the center and SM indicates' the dagger is in the acceleration channel ⑴), the position of the narrowest cross section at the beginning, otherwise The distance from Pd, "is the constant distance of the dagger: the distance of the acceleration channel squat. Large Leff indicates the length of the yarn opening area, and _ large indicates the length of the yarn winding area. If the angle is not larger, the yarn opening area is enlarged backwards. The more you get. Figure 2 shows an entire winding head or nozzle head (20) with a built-in nozzle core ⑸. Untreated yarn 的) via a yarn feeder

In the exit area 缔 of the winding nozzle, there are 23:;, one by one Compressed air connector (at the nozzle _ 21 at the transport speed VT warp _ second yarn feeder ((-) warp-quality sensor ⑽ (for example, those with the mark name II 17 are not ATQ)) pass, measure in it The associated yarn tension, > pull force / year of CN) and the partial i (^%) of the instantaneous pull force, the measurement signal is sent to 1 brain single print 7). The relevant quality measurement is the most appropriate prerequisite for the product Condition. This value is also an indicator of yarn quality. In the air winding process, ^^ |, V7 ±. ^ If there is a ring size value, the quality measurement is again difficult: compared with The customer thinks it can be called good quality, and the deviation degree of the present invention is even better. Using & then the system is possible. 为, 仏, and its deviation degree can use a line tension sensor. (2 6) AT value-for display. Line confirmation, analysis, and several single characteristics are used. The force sensor will specifically wire tension after the nozzle is rolled. The detection is analogous to the electric bluff = formula. Here, the average value and variation of the measured value of the thread tension are continuously different from AT i. The size of the AT value is related to the structure of the yarn and is determined by the user according to it. It can be calculated based on individual quality requirements. If the variation of the wire tension or the tension of the wire (uniformity) changes during production, the value of Δτ also changes. The lower limit value and the place where the lower limit value is located can be used with a glass mirror ). Knitted fabric f woven fabrics are obtained. They are different according to quality requirements. The 4 points in this atq test are that different types of interference can be detected at the same time in the program, for example: the position of the scrolling effect is the same Properties, long yarn breakage, nozzle contamination, rebound ball distance, hot pin temperature, compressed air difference, insertion area (POY-SteckZone), yarn front (lage lage), etc. 0 Please refer to the following Figure 3, which is a preferred embodiment of the entire nozzle core ，, whose cross section is enlarged at a high magnification. The external fit shape (EinPaSSf0rn) should fully match the nozzle core of the prior art. This point is mainly about 18 200422451 Built-in material, the hole diameter B , The total length L, the nozzle head height KH, and the distance LA of the compressed air joint (pp,). Studies have shown that the optimal blowing angle point must be greater than 48. The distance of the relevant compressed air hole (15) relative to the acceleration channel It is very important. The yarn passage (4) has a "yarn introduction cone" (6) in the wonderful entrance area (indicated by the arrow (16)). The backward-oriented waste air flow is subjected to the oblique compressed air hole (1 5) The compressed air directed along the yarn conveying direction decelerates. The amount "X" (Figure 6) indicates that the air hole should deviate from the diameter d by at least a section of the narrowest cross section (3). [Arrow (16)] The winding nozzle (1) or nozzle core (5) has a "yarn introduction cone" (6), a cylindrical central section (7), a cone (8) [the tapered portion is equivalent to the acceleration channel (^) at the same time], and a widened chamber (9). The scrolling chamber is perpendicular to the air-defining A-shape (12), which can also be designed as an open funnel. Figure 3 shows a winding nozzle with three compressed air holes (1), which holes are offset from each other by 120. , And open into the yarn channel (4) at its own point \.

The dimensions Bd, EL, and the built-in length should not only be equal, but can be made with a tolerance of ㈣. In addition, the λ-shaped and region are also made the same as the previous technology, with a corresponding semi-D projectile (14) can be any shape: spherical, oblate or even :: anti-rebound thick () here The exact position in the exit region can always be maintained by maintaining the external metric 19 200422451 (corresponding to an identical 柘 μμ, 隹 gap sn).

In Lai's winding coil nozzle, the important point is that the round-shaped wall surface (2)) η θ +, + has the highest quality in the acceleration channel area (22). And ok. . Figure 5 shows an entire nozzle head (20), which has a nozzle core (5) and a rebound body (14), which can be adjusted via an arm (27) and locked in Baizhi Wei The body (⑻ 中. To thread the yarn, the rebound body (14) is pulled or turned away from the working area (30) of the winding nozzle with the arm (27) in a conventional manner corresponding to the arrow (29). Compression Air is supplied from a shell chamber (31) through the compressed air hole to the core of a mouth—the clamping strip (K1_bride) (32) is sandwiched on the carcass (33). If no ball is used, the rebound body can also be The shape of the ball cap is shown in the left side of Fig. 6 in a schematic manner.

Yarn opening area 0e-Z £ starts in the area of the compressed air supply source p not far in front of the acceleration channel, and compared to the solution of EP 0 088 254 The shorter yarn opening area 〇e — Z is much larger. 20 200422451 The important illustration of Figure 6 is that the yarn tension of the prior art (curve T3U) with Mach number < 2 and the yarn tension with Mach number greater than 2 Comparison of the coil winding nozzle of the present invention and this Xinlai nozzle coordinate chart. In the figure, the yarn tension of the vertical axis (unit CN). It can be seen in the curve T311 that the yarn tension exceeds 500 m / min when the production speed is exceeded. Significantly lowered. At about 650 meters, the point above is the coiling operation of the nozzle using e 2 088 254 '.

The 'value B3' is significantly smaller in the two lower yarn patterns. However, especially in short intervals, tight positions and still dense positions with many loops can be seen. The decisive point is that the yarn pattern will behave very differently under load. If the yarn pattern (upper and middle) according to the prior art is pulled, the loop will loosen too much and the tension will be released. After the tension is released, the loop is still almost completely on the yarn pattern. This means that the quality of the winding can be significantly improved from two aspects, which can be seen so far. The measured yarn fineness was confirmed. In addition, there is a fact worthy of Note: According to the thermal effect of international patent WO 99/451 82, its quality and: The rate can also be improved correspondingly with the present invention, EP! 058 745 = 2 22 200422451 is a part of the whole of the additional combined effects ^ In the following, please refer to Figure 帛 9, which shows the schematic-view diagram of the novel winding process. The respective program stages are continuously displayed from top to bottom. Smooth yarn. 〇 经由 from top via a first yarn feeder (LW1 ) At a given conveying speed to a winding nozzle (101) and pass through the yarn channel (104). Via the compressed air channel (103) (they are connected to a compressed air source (PL) to highly compress (And preferably unheated) air is blown into the yarn channel (ι 04) along the yarn conveying direction at an angle α. The yarn channel (104) is then tapered opened so that in this tapered section (1 02) produces a greatly accelerated supersonic air flow, preferably larger than Mach 2. As described in the above-mentioned WO 97/30200 embodiment, the shock wave causes the original contraction effect. The air blowing position (105) enter the first section of the yarn channel (104) until the cone becomes wider The first section of (102) is used to make Auflockerung and open the smooth yarn. Therefore, the individual long-run text to the supersonic flow effect. The enrollment effect depends on the existing air pressure (9 Bar ... 12 bar up to 14 bar and more) still occurs in the conical section (102) or in the exit area. There is a proportional relationship between the Mach number and the winding effect, the larger the Mach number The stronger the impact, the denser the coiling effect '. For the production speed, there are two important parameters: • the required quality standard • the shaking action (Schlackern), which further raises the day when the transport speed may cause the coiling effect to collapse (Zusammenbruch). The meaning of the abbreviations in Figure 10 is:

Th. Vor · · Thermal pretreatment, if necessary, only yarn heating or hot steam 23 200422451 G. niech ·: Yarn processing (supersonic flow) by mechanical action of compressed air flow.

Th · Nach ·· Heat treatment with hot steam (if necessary, only heat or hot air D: Steam: Compressed air production speed can be increased to 15,000 m / min with additional heat treatment without affecting The coil effect does not need to be shaken (Schlacken), the limit of which is determined by the existing test equipment. The best coiling quality can be achieved at a production speed much higher than 800 meters per minute. Surprisingly, the inventors found that One or two completely new quality parameters, of which even the more stated law (higher Mach number = larger impact = dense coiling) can only be confirmed in all experiments. The parameters found on the one hand are Heat treatment before and after a winding operation 'Another aspect is to increase the Mach number by increasing the air pressure and designing the acceleration channel. A) Heat treatment or retraction (Relaxieren) An important quality criterion for judging the winding effect The tension of the yarn coming out of the winding nozzle is used, and this value is also used as the amount of denseness of the winding effect. The tension of the yarn on the winding yarn (106) is adjusted between the winding nozzle (τ J)) and an early spinning machine (LW2). Here, the winding nozzle (TD) and the yarn feeder (LW2) are adjusted. In the area between them, heat treatment is performed on the tensioned yarn. The yarn is heated to approximately 180 ° C. The first test was successfully completed using a hot pin (Hotpin) or a heated coarse silk spinning machine (Galette) and a hot plate (j) 〇tplate (non-contact method), the results were unexpected In terms of delivery speed, 24 200422451, the quality limit can be greatly increased. The reason is that the above heat treatment is believed to have a fixed effect on the winding yarn and a shrinking effect at the same time, so it contributes to the winding effect. b) Thermal pre-treatment More unexpectedly, thermal pre-treatment also has a positive effect on the winding process. Here, in the supersonic range, the combined effect between the contraction and the yarn opening effect in the section between the blowing position in the air blowing yarn channel and the first part of the tapered widened part should be this The cause of the result.

2. The yarn is heated to reduce the tenacity, so it is beneficial to form a yarn loop in the winding process p. For this reason, the hot plate and hot selling t can also be used as a heat source to successfully complete the j-test. In addition, the reason for this effect is as follows: the yarn is also treated with rain, and the negative caused by the air expansion and heat absorption in the winding nozzle: the internal effect can be avoided, so in the heated yarn, the winding effect can be improve. At your high conveying speed, 1 quantity-part-stays in the yarn itself until the area where the loops are formed.

Figure 9 shows the use of the treatment agent, the treatment agent can be hot air, hot air, or other hot gas' these treatment agents on the running yarn are not far apart from each other or immediately after the treatment, In this way, this means (Verfahrenseingriff) 廿 α 田 丨 g 1ί is not isolated from each other, but is a combination of common points of action between the two V spinning machines. #Just express it, the yarn is only held at the front and the end, while bamboo slugs are used as a means of air treatment and heat treatment. This heat treatment operation is the tension in the long edge, ', or in the yarn (this tension is generated mechanically by compressed air)', the mechanical action of _dry A, ', α in Figure 10 a to d With heat effect 25 200422451. This thermal effect is in front of or behind the original winding operation in space. Here, even if a smaller value is used, the yarn heating effect has a positive effect on the winding effect. Figure 1GGd shows some so-called heated and driven roving spinning machines (Galette) for heat treatment-some important important possible uses. Each temperature value in the roving spinning machine indicates whether it is a heating position. In this sense 'it is also possible to use a hot plate or the continuous steam chamber of the invention in all drawings.
