Abstract

A yarn (12) consisting of several component yarns(11,11.1,11.2) which are crimped together is collected at a wind-up (10). Each component yarn (11,11.1,11.2) has its own forwarding element (21,21.1) but the component yarns are crimped or texturised together into a yarn plug in a crimping element (22).

Description

The invention relates to a method and a device according to the preamble of the independent Expectations.

From a European patent publication No. 0485871 B1 (Barmag) is a Process already known in which differently colored, each from a spinning shaft Coming partial threads each via a preparation and by precompacting to be subsequently stretched by means of a pair of godets, in textured in a texturing nozzle, cooled on a cooling drum, together in a swirling nozzle compacted and then wound up.

This is the compacting between the preparation and the stretching godets around interlacing nozzles per thread, which are the known per se Cause turbulence. Such a disadvantage for texturing In this process, bottlenecks are created by stretching using the stretching godets dissolved again before the partial threads get into the texturing nozzle.

Differenz" zwischen den beiden Filamentbündeln betrifft ihre Farbe, indem ein Mehrfarbengarn hergestellt wird. Es ist deshalb vorteilhaft diese Art Verfahren mit bezug auf zwei verschiedenfarbige Filamentbündel zu erklären, wobei die Farbdifferenz nicht das wesentliche Merkmal der Erfindung ist. Wünschbare Effekte" in bezug auf Garnstrukturen und Erscheinungsbild des Garnes können durch Kombinieren von Filamentbündel erhalten werden, welche andere Unterschiede" aufweisen, beispielsweise solche welche in der US-4,025,595 erwähnt sind.The present invention relates to the improvement of a method for producing yarn as published in US Pat. No. 4,025,595. Such a yarn contains at least two different filament bundles, each bundle being swirled separately and later the bundles being swirled together to form the yarn. The obvious one

Difference "between the two filament bundles concerns their color by producing a multicolor yarn. It is therefore advantageous to explain this type of process with reference to two filament bundles of different colors, the color difference not being the essential feature of the invention. Desirable Effects "on yarn structure and appearance of the yarn can be obtained by combining filament bundles, which others Differences ", for example those mentioned in US Pat. No. 4,025,595.

The process explained in US Pat. No. 4,025,595 was intended for relatively low spinning speeds in comparison with the modern spinning processes today. Furthermore, textured products could only be obtained by means of successive processes with intermediate products, the so-called Spin-Draw-Spuhlverfahren "as mentioned in the aforementioned US patent.

The production of similar yarns using modern on-line processes has proven difficult, in that a texturing step is included in the continuous process line. The swirling step published in U.S. Patent 4,025,595 tends to interfere with a texturing step. An attempt to solve this problem can be found in EP-B-485 871 and in EP-A-434 601. In these cases, the bundle of filaments is treated above the texturing step to ensure that the two steps can be separated from each other with the aim of To maintain induvidiality "of the two filament bundles in the end yarn. These processes have achieved a degree of success, but they do not give the yarn manufacturers the reliability and flexibility required in view of the fact that Yarn manufacturers "form a different group of organizations with different marketing and product strategies.

The new invention includes a method of making a yarn with a Plurality of different filament bundles, the method comprising the step of Unification of the filament bundles involves, for example, by swirling to thereby to form a yarn. The process is characterized by the process step in which at least one bundle of filaments individually above the connecting step and below all the previous stretching, texturing and combining steps is treated. Individual treatment can be provided to measure the induvidiality of the treated filament bundle after the bundles have been joined obtained yarn product to increase. Individual treatment can (for example) include a treatment that reflects the compactness of the fibril bundle increased (for example by swirling) at the entrance of the connection step. In the preferred embodiment, each bundle of fibrils becomes individual and immediate treated before entering the connection step.

Insofar as previous treatment steps which brought the filament bundles together (for example texturing in a common texturing chamber) were used, it is necessary to separate the filament bundles again, if this is required in order to enable an individual treatment according to the present invention. In the preferred embodiment, the filament bundles are kept separate until the uniting step. On the other hand, it is not always possible for economic reasons to achieve this separate treatment until union ", which is why various measures can be adopted to improve the keeping of the filament bundles separately, even if they are brought together before the union. Such measures include swirling and twisting the individual bundles, for example before texturing together.

• Titer
• Anzahl der Fibrillen im Filamentbündel

Of the Difference "between two filament bundles which are processed according to the invention contain differences in

• colour
• Titer
• Number of fibrils in the filament bundle
• Polymer type
• Dyeability
• Cross section of the fibrils
• Additives in the bundles of fibrils

The invention provides a highly controllable method for influencing the structure and / or the appearance of the yarn product, that is, it is a highly efficient method for producing Effects ". This is thanks to the fact that the union step follows immediately after the individual treatment step, because there are no intermediate process steps which tend to reduce the effect or which have to be taken into account in order to determine the extent of the individual treatment. For example, one type of individual treatment includes the step of bringing the fibrils of a bundle of fibrils together locally (by forming Bottlenecks "), the local "connections along the length of the filament bundle are provided at intervals. In a method according to the invention, the number of local connections per unit length of the filament can determine the tightness of the connection in location and the uniformity of the connection steps along the length of the filament bundle, with respect to the desired one The effect can be controlled without restrictions, given by other procedural steps besides the connection, as already proposed in US Pat Effects " Balancing "the individual treatment with the collective treatment in the connecting step.

With reference to the method described in WO 96/09425 (Obj. 2509), is an example described an embodiment of the invention, wherein the main elements in the A are shown. For the sake of simplicity, only two filament bundles I and II are shown. After the filament bundles have been spun separately (spinning beam and nozzle arrangement not shown), they are by means of a first roller G1 and a second Roll G2 stretched before being wound in a winder W. (the A is only schematic). In the modification according to the invention the filament bundles are treated individually at T1 and T2 and the treated ones Filament bundles are combined into a yarn in J.

B shows schematically an untreated filament bundle - fibrils from untreated filament bundles are free from those from another untreated filament bundle to unite "when the two filament bundles are brought together. A method to ensure the freedom of such fibrils with respect to the Union "to imitate is that compact spots "S is provided in each bundle, as shown in Fig. C. Such compact spots can be formed, for example, by swirling. Such compact spots arise during swirling when an air jet is blown across the running fibril bundle, which divides the bundle of fibrils into two parts and then causes an oppositely directed twist in both parts, which is released again after leaving the air jet, the fibrils of the two bundles of fibrils intermingling during this untwisting and thereby causing the bottlenecks rear constriction, seen in the direction of travel, the same thing again, another method the freedom of the aforementioned Limiting union "consists in incorrect twisting of the filament bundle, as shown, for example, in Fig. D. It is generally known that it is not possible to use one real twist "in a running yarn (filament bundle) by means of false twist between two ends of the yarn. On the other hand, it is possible to sort Reverse twist ", as shown in Fig. D, in which the filament bundle shows a first twist direction in the region R1 and a second twist direction in the region R2 - it is also possible to apply this twist pattern fix "in which twist stops are brought into the yarn structure. The introduction of Twist stops "can be achieved by combining a treated bundle with another bundle to form a yarn, as shown by J in FIG. A.

Fig. E shows schematically a device by means of which on a filament bundle compact places "S can be introduced. The device comprises a common inlet (shown with the arrow P) and three exits (shown with small arrows within the figure.). The filament bundle is successively guided past the three exits and is thereby swirled. Similar Swirling processes can be carried out in Unification step "can be used for bringing fibril bundles together to form a yarn, the air pressure which is used in the merging phase probably being much higher than in the individual swirling, for example 0-3 bar in the individual swirling (e.g. T ₁ and T ₂ ) and approximately 6 bar in the union vortex (J) The distance between units T ₁ and T ₂ from unit J should be large enough to avoid mutual interference unless such interference is acceptable in relation to the effect to be achieved (random influences).

The arrangement shown in Fig. A is simple ", insofar as the filament bundles can be kept clearly separate from one another (with a spacing between the filament bundles) up to the unification step J. However, this is not always possible, as is shown, for example, in the arrangement of EP-A-434 601 In such cases, it is desirable to provide additional funds to a Avoid fusing "the fibrils of the filament bundles before (controlled) swirling in stage J. With the term Merging "is to be pointed out to the tendency which exists when two originally separately guided filament bundles mix in an uncontrolled manner by the two filament bundles coming into contact with one another if no measures are taken to avoid this mixing. Suitable measures are however known from the aforementioned prior art.

The invention is not restricted to the treatment of the filament bundles by means of air nozzles. The treatment of the individual filament bundles and the joining of the bundles can also be done, for example, by using adhesive material or by forming Depending on the effect that is to be achieved in the yarn, it may also be desirable to leave a filament bundle untreated before forming the yarn by combining the filament bundles - the untreated bundle gives the yarn one fluffy "effect.

The advantage of the invention is that by compacting the individual threads (T1 and T2 in Fig. A) after texturing (Fig. 1-8) and before than later than Collective compacting refers to compacting the combined partial threads (J in Fig. A) the quality i.e. safety in color separation and thus color recognition of the individual partial threads in the yarn repeatable compared to the prior art is improved.

Before the description of the figures, let's look at some more detailed solutions for implementation the compacting, or the texturing, to which in the course of Description of the other figures, reference is made.

Doing so under Compacting "means the compression of the fibril bundle either over the entire length of the fibril bundle by means of a false twist or selectively by means of a swirling nozzle.

For example, swirling nozzles are used as compacting agents can be known from US-4,025,595, US-3,364,537 or US-3,426,406 and from EP-0434601 A1 false twist nozzles are known, which are also in the type described therein can be used as compacting agents.

Furthermore, each of EP-0039763, EP-0110359 A1, EP-0123072 A1, EP-0123829 a texturing nozzle is known, which is advantageously hinged to enable 16 Insert one or more threads for texturing, whereby the Texturing takes place after the texturing nozzle is closed again. Because such texturing nozzles work in the conveyor section according to the injector principle, they are not only able to to continue feeding the threads after the nozzles have closed, but also if necessary to be sucked in so that non-opening texturing nozzles can also be used to bring the threads into the texturing nozzle. Another option is there in bringing the threads into and through the texturing nozzles using a suction gun.

Likewise, a texturing nozzle is known from CH-680140 A5, which at the entrance Injection nozzles, which, to generate a protective twist in the thread, eccentric open into the yarn guide channel.

In the texturing nozzles known from EP-0039763 A1, EP-0123072 A1, EP-0123829 A1 the partial thread is heated and conveyed in one channel or Chamber trained heating and conveying element, and the grafting or curling, or texturing in a second chamber in which the blown heated Gas can escape again, so that a plug can be removed from the chamber can. To cool the plug, it is placed on a transporting cooling element, for example, a rotating cooling drum.

Another test device is known from EP-310890 A1 (Rolltex), which a heating and conveying channel for heating and conveying the thread, or the yarn and a needle roller connected to it to form the yarn plug composed, the plug after the needle roller on a cooling drum, to cool the graft.

Likewise, texturing agents are known from US Pat. No. 3,255,508 (Mitsubishi) assemble from a heating and delivery nozzle and a subsequent cooling drum, the plug formation due to the impact of the heated and conveyed thread arises on the cooling drum.

Fig. 1 shows a device for producing a multi-colored yarn with here, for example three spinning shafts, each with differently colored partial threads 11 or Generate 11.1 or 11.2. These partial threads 11, 11.1, 11.2 are each via a preparation agent 2 performed, which is usually an oiling agent.

Such yarns can also consist of two or more threads.

After the preparation agent 2, the partial threads 11-11.2 each arrive separately in an associated one referred to as precompacting means 3, which either a known swirling agent or preferably a known swirling agent False twist means, both means already at the beginning as state of the art were mentioned.

After the precompacting means, the partial threads 11-11.2 are stretched on godets 4 stretched to a predetermined dimension heated or heated, i.e. in the area the glass transition point, or brought into the thermoplastic area. At Swirling is used as a precompacting agent provided such that when stretching the interlaced threads 11-11.2 the Swirl constrictions at least partially again, depending on the type of swirl be saved in order not to lose any of the texturing quality of the yarn.

After the stretching godets 4, the partial threads 11-11.2 are together in a texturing nozzle 5 textured, primarily due to the partial threads in a heating and conveying element 6 of a conveyor system acting on the injector principle is sucked in, warmed up and in a curling element 7 to be promoted there due to the escape of the heating and Conveying gases between fins 32 or other equivalent air permeable Elements and the resulting reduction in conveying speed and further resulting friction of the individual fibrils of the threads on the wall of the cooling and crimping element 7 are compressed into a plug, which then is placed on a cooling drum 16. From the operator the plug before or after the cooling drum 16 in crimped threads 11.3 - 11.5 divided, which also applies to the figures to be described 2 to 6 and 8, and via a take-off roller 33 and, if necessary, via deflecting thread guide 31 into an associated, as post-compacting means 8 - in connection with FIG. A as T1 or T2 - designated compacting agent, with the post-compacting agent 8 either one known per se or one in connection with FIG. D False twist mentioned or preferably a swirling agent known per se is. The above-mentioned detection by the operator takes place with the help of a known suction pistol, the separation into the partial threads manually and with Help from thread guides, not shown here, happens for each thread.

After the post-compacting means 8, the partial threads 11.3-11.5 are, if necessary, over Deflection thread guide 31 combined on a godet 34, then in one referred to as collective compacting means 9 or in connection with FIG. A as J. Compacting means compacted together, that is, either preferably swirled together with means known per se or rotated wrongly together, around the yarn 12 again over a godet 35 and then in the winder 10 to be wound up. Since these godets are conveyor rollers, can optionally on one or both godets 33 or 34 in front of or on the godet 35 after the compacting means 9 or without all three godets 33, 34 and 35, which has to be determined by tests depending on the material.

In the latter case, the threads are directly from the winder 10 from the cooling drum 16 and pulled by the post-compacting means 8 and collective compacting means 9.

FIG. 2 shows a variant compared to FIG. 1 for texturing the partial threads 11-11.2 after the stretch godets 4 a heating and conveying element 15 with the same functions as the element 6 and then one known per se from US-3255508 Cooling drum 16 with the additional function of element 7, i.e. of the Grafting is formed on the cooling drum 16 and cooled. The other elements correspond the elements already described for FIG. 1 and are therefore not mentioned again.

Fig. 3 shows a variant of Fig. 1 instead of the spinning shafts 1 individual coils with dyed partial threads, also called dyed bobbins 13, and as a further variant for the purpose of texturing the partial threads marked here with 14-14.2, according to the Stretching godets 4 a heating and conveying element 17, which functionally the aforementioned Corresponds to elements 6 and 15, with subsequent needle roller 18 and subsequent Cooling drum 16 and plug deflection element 30 provided between them, the combination of elements 17, 18, 16 and 30 described in EP-0310890 A1 is why reference is made to this EP document for further details. The remaining Elements correspond to the elements of the aforementioned figures and are therefore not mentioned again.

On the other hand, it should be mentioned that the use of supply spools 13 (e.g. colored ones Spools) instead of spinning chutes 1, possible for all variants of the other figures is.

4 shows a combination of stretch godets 4.1 with a known one Surface heating element 19 which is provided between the two stretch godets and in addition to the heating by means of the godets 4 or only the heating of the sliding threads 11-11.2 or 14-14.2.

FIG. 5 shows a variant of a part of FIG. 1, insofar as a texturing nozzle 20, which has a suction part 21 for each thread 11-11.2 or 14-14.2 issued a protective twist to the corresponding thread, followed by the partial threads in the heating and conveying element 21.1 by means of the conveying medium heated and conveyed and in the subsequent crimping element 22 into one Plugs are curled. The individual heating and delivery channels of the Partial threads combined in the crimping element, i.e. that imaginary levels of symmetry of the individual heating and delivery channels intersect in front of the crimping element. The other elements correspond to the elements already described and will therefore not mentioned again.

6 shows, compared to FIG. 5, a further variant of a texturing nozzle in the a texturing nozzle 23 for the filaments, a heating and conveying element 24 and also has a common crimping element 25 in order to separate the individual partial threads for heating and conveying, and texturing together. This leads to the individual Heating and delivery channels of the partial threads side by side into the crimping element, i.e. that imaginary levels of symmetry of the individual heating and delivery channels outside the Cut heating and conveying element 24, the intersection not being shown.

The other elements correspond to the elements already described and are therefore not mentioned again.

FIG. 7 shows a variant of FIG. 6 insofar as there are three individual texturing nozzles 28, each with a heating and conveying element 26 and one attached crimping element 27 per thread, the three plugs from the corresponding crimping element either via conveyor rollers 29 or directly, depending on the arrangement, placed side by side on a common cooling drum 16 so that the division into partial threads mentioned for FIGS. 1-6 and 8 here is no longer necessary. The other elements correspond to those described so far and are therefore not mentioned again.

FIG. 8 shows a variant of FIG. 3 in that the cooling drum 16 is omitted here is and in its place a cooling air application element 36 and a cooling air suction element 37 is provided around a predetermined area of the needle roller 18, by means of which the plug located on the needle roller is cooled and then via a deflecting thread guide 31 onto the godet 33 and further as before described is performed. The variations described for FIG. 1 can the use of the godets 33, 34 and 35 also for the arrangement of the described Elements of this figure, as well as for the arrangement of the described elements of all other figures can be used.

FIG. 9 shows a texturing nozzle which can be used in the devices of FIGS. 1 to 8 38, which is provided with a heating and conveying element 39, which for each thread its own heating and delivery channel as well as its own crimping channel in the Contains crimping element 40.

The advantage of this design compared to the three individual texturing nozzles of FIG. 7, exists in terms of heat technology and production in the compact embodiment, which can lead to cheaper manufacturing and operating costs.

In Fig. 10 the cross section of the crimping element 40 is shown, which is Ripple element from the two outer walls 41 and the intermediate walls 42 and the slats 43 located between them. There is a space here provided for the plug formation, which is shown with the thread tangle 45 shown is. Furthermore, there are the outer walls 41, the intermediate walls 42 and the slats 43 fastened to the heating and conveying element 39 by means of an upper ring flange 46, during the cohesion of the outer walls 41, the intermediate walls 42 and the Slats at the exit of the crimping element 40 by means of a lower ring flange 47 takes place.

With 44 it is shown how the air from the individual channels (only in shown a channel) can escape the crimping element.

The thread-surrounding parts of the texturing nozzles are advantageously around the part threads easy to insert, according to the aforementioned EP-0039763 etc., can be opened, which is why the texturing nozzle 38, as mentioned earlier, can be separated into two halves is what is indicated by the imaginary plane of symmetry 48.

FIG. 11 shows a variant of the cross section of FIG. 10 in the slats 49 are arranged radially, in comparison to the parallel arrangement of the slats 43 in Fig. 10. The other elements correspond to the elements of Fig. 10 and not repeated.

It should also be mentioned that in the figures, the partial threads to be crimped up to and with the texturing agent with 11-11.2 or 14-14.2 and that after the texturing agents crimped partial threads up to the collective compacting agent 9 with 11.3-11.5 or 14.3-14.5 and subsequently marked as yarn 12.

Likewise, in all variants of Figures 1-11 either partial threads from the spinning chutes 1 or processed by the coils 13.

Likewise, where necessary, deflecting thread guides 31 are provided in the figures is shown schematically in the figures.

It is understood that advantageously for all elements provided with an injector principle a swirl distribution principle shown with CH-680140 A5 can be used can, in order to impart a protective twist to the threads passed through the texturing nozzle, which, in addition to the otherwise mentioned compacting of the partial threads, ensures that in the case of multiple threading through a texturing nozzle, the individual partial threads themselves not getting caught up in each other, but essentially remaining side by side, the upper twist stop of the corresponding part of the thread in the thread running direction preceding godet of pair of godets 4 is.

A protective twist is particularly useful if the threads as shown in FIGS. 1-5 be textured in a common texturing nozzle.

It should also be mentioned that when the false twist principle is used to compact the partial threads after the preparation means 2, these preparation means 2 can be used as a twist stop if no deflection thread guides 31 are used for any reason, and that the term differently coloring partial thread "is to be understood in such a way that such threads in the color process, when using, for example, the same color, contain subtly different but desirable color effects.

It should also be mentioned that with the post-compaction mentioned using swirling nozzles, the compacting effect by means of pressure (bar) and / or quantity (kg / h) and / or the temperature of the gas, e.g. Air or steam is changed by changing the Number of intermingling per unit length of thread more or less selectable different fails. This is used according to the invention in order to achieve the color effect of the manufacture yarns in addition to varying the color effect by selecting the colors to vary.

In addition, these parameters (pressure, quantity, temperature of the gas) per thread be chosen differently, so that from thread to thread a difference in the swirling and thus in the intensity of the color separation or color recognition in the yarn.
