Definitions
- the invention is in the field of textile technology and relates to a method and a device for the gentle removal of excess liquid from high-speed threads according to the preamble of independent claims 1 and 14.
- Manufacturing processes especially of synthetic threads consisting of a plurality of fibrils, often comprise one or more process steps which are associated with a treatment of the thread with a liquid.
- Such process steps are, for example, quenching, stretching, dyeing, impregnating or texturing such threads.
- Such liquid treatment processes are preferably carried out in closed chambers which have narrow inlet and outlet openings for the continuous thread or threads.
- the chambers for liquid treatment and in particular their thread outlet openings are designed in such a way that the liquid remains in the chamber and only small quantities can escape through the openings, it cannot be prevented that the thread or threads emerging from the chamber itself carry liquid with them, then on the liquid treatment chamber following thread guide elements is thrown off with spray formation.
- Such spray mists contaminate neighboring machine parts and represent a loss of treatment liquid, which should advantageously be avoided.
- the threads are still contaminated with too much liquid even after the thread guide elements and may then have to be dried according to the method, using considerable amounts of energy.
- DE-A-2 158 932 discloses treating yarn with liquid treatment agents, the yarn being passed through a horizontally arranged bath and where deflecting rollers are subsequently provided on the bath, on which the Due to the centrifugal force, yarn releases liquid, which is collected on the walls and returned to the bath.
- the liquid content in the thread after going through the process should be adjustable.
- the liquid removed from the thread should be collected so that it can be returned to the liquid treatment.
- the method for removing excess liquid from the thread should be able to be operated with a minimum of energy and it should treat the thread so gently that it is also suitable for very sensitive threads and is applicable at every stage of a thread manufacturing process.
- the process should have as little braking effect on the thread so that it can also be used immediately after a stretching chamber.
- the method is said to be particularly applicable for high thread speeds, ie above 2000 m / min.
- the method according to the invention represents a combination of various sub-methods suitable for the removal of liquid from high-speed threads.
- the thread is deflected, with liquid being thrown out of the thread by the centrifugal force in a known manner
- the thrown-away liquid is directed away from the thread running zone and thirdly, the whole process takes place in a closed chamber in which a negative pressure is generated by the thread passing through , which contributes to the easier evaporation of the liquid.
- the negative pressure generated by the continuous thread can also be increased by additional means.
- the air directly surrounding the thread which is entrained by it, is peeled off from the thread and replaced. Obviously, in this fourth sub-process, the acceleration of the air in the direction of the thread and the resulting shear forces between the thread and the ambient air act on the thread in a drying manner.
- the process step combined from the four partial processes described is repeated immediately in succession, possibly with slightly varying process parameters, preferably three to four times. This makes it possible to achieve a high drying effect with only very small deflection angles, which is significantly gentler on the thread than a single deflection step by a correspondingly larger deflection angle.
- the process has only a very slight braking effect on the thread, so that it can also be used after a stretching bath without part of the stretching process only taking place during the drying process.
- Figure 1 shows in a very schematic way a process step of the inventive method.
- a wet thread F.1 is deflected by a deflection element U and liquid is thrown out of it (broken arrow A).
- the ejected liquid is deflected away from the thread by a chicane B inclined away from the thread in the direction of gravity.
- the thread runs over the deflection element U, it simultaneously passes through a narrow gap S.
- the air that directly surrounds the thread is peeled off from the thread, which is indicated in the figure by the drawn arrows L.1.
- the thread F will entrain new ambient air (solid arrows L.2), which must be accelerated accordingly.
- the process step takes place in a space surrounding the thread, except for narrow openings for thread inlet and outlet, in which the thread running creates a negative pressure.
- the thread leaves the process step described as drier thread F.2 and is advantageously passed into one or more directly following process steps of the same design in order to be gradually dried to a desired degree of drying.
- the drying effect of a method step according to the invention is greater with a larger deflection angle ⁇ , with a smaller deflection radius r, with a narrower gap S and at a lower pressure.
- a method variant of that illustrated by FIG. 1 consists in that the deflection of the thread and its passage through the narrow gap are locally separated from one another.
- FIG. 2a shows how the method according to the invention used to remove liquids from high-speed threads, which, for example, consists of 4 process steps as described in connection with FIG. 1, takes place in a corresponding device which is shown very schematically.
- the wet thread F.1 loaded with liquid is passed through, for example, three chambers K.1-3 and leaves the chamber K.3 as a dry thread F.2, from which most of the liquid has been separated.
- the thread is deflected by a small deflection angle ⁇ , preferably 0.5 to 10 °, for which purpose deflection elements U.1-4 with a radius of curvature r of 0.5 to 5 mm are preferably used .
- the deflection angle is advantageously not chosen to be larger, since a small deflection angle is gentler on the thread and since the repeated deflection can achieve the same liquid-separating effect as with a single deflection by a larger deflection angle.
- the walls 20.1-4 which close the chambers in the direction of the thread and separate them from each other carry the deflection elements U.1-4, form the columns S.1-4 and at the same time function as baffles B.1-4 which act in the form of spray mist A.1 -3 Deflect the flung liquid away from the thread by tilting it in the direction of gravity.
- the walls 20.1-4 are shaped such that their two parts (for example. 20.1 and 20.1 ') have the same height on both sides of the gap in the thread direction. It is also conceivable to shift these heights in the thread direction so that one wall part follows the other in the thread direction.
- there is apparently no chicane B.4 for the fourth and last process step for the fourth and last process step. If the wall parts 20.4 and 20.4 ', on the other hand, are displaced relative to one another in the thread running direction, as is indicated in FIG. 2b, the wall part 20.4' can still partially take on the function of a chicane B.4.
- the chambers K.1-3 are closed to the outside except for the thread inlet opening, which represents the first gap S.1 traversed by the thread, the thread outlet opening, which represents the last gap S.4, and the suction openings 21 and 21 ', through which the liquid collected in the chambers is aspirated. Since the high-speed thread creates a negative pressure in the chambers, the liquid must be actively sucked out of the device.
- the individual chambers are interconnected through the openings 22.1 and 22.2 (22.1 'and 22.2'). These openings and the suction openings 21.1 and 21.1 'are each arranged at the lowest point in the direction of gravity of the chambers, so that in the Chamber liquid is driven by gravity from one chamber to the next and from the last against the suction.
- a completely soaked thread of 110dtex f34 made of PA66 can be redirected four times by 3, 6, 6 and 3 °, i.e. a total of 18 °, to a moisture level at a throughput speed of 3000m / min of about 11%, so that subsequent rolls, thread guides and the entire exit zone remain practically dry.
- the energy consumption for the process (suction) is low because the flow cross-section over the inlet and outlet opening is very small.
- the design of the schematic device which is illustrated by FIG. 2a, is strongly characterized by the fact that the general thread running direction corresponds to the direction of gravity. This is an advantageous arrangement because it allows the device to be designed in a simple manner. From the principle of the method, however, it is not imperative that the general direction of the thread is chosen in the direction of gravity. Devices for other thread running directions will differ from the device shown schematically primarily by a different design of the walls 20.1-4.
- the variant of the method according to the invention shown in FIG. 2a is suitable for points in the higher-level process at which the thread itself does not have to be deflected. For this reason, the thread is deflected alternately in different directions in such a way that the sum of the deflection angles of the individual process steps is zero, that is, the thread is not deflected over the entire process.
- the method according to the invention for removing superfluous liquid from a thread begins If a point of the higher-level process is used at which the thread has to be deflected, deflections can always be provided in the same direction for the partial steps of the method according to the invention, such that the sum of the deflection angles in the method steps is equal to the desired deflection angle.
- a corresponding scheme for a method with four substeps is shown in FIG. 2c.
- FIG. 2d An example of a corresponding device variant is shown in FIG. 2d. As in FIG. 2c, it is a device with which the method is carried out in the form of four sub-method steps and which is suitable for a deflection point in the higher-level process.
- FIG. 2 Further variants of the method described in connection with FIG. 2 can consist in that there is no deflection of the thread at the entrance to the first chamber in the direction of the thread and at the exit from the last chamber. Furthermore, all chambers can be connected to a central suction device by a separate suction device.
- FIGS. 3 and 4 now show in detail as an example an embodiment of a device with which the described method according to the invention can be carried out. It is a device with which four threads running parallel in the direction of gravity can be freed of liquid.
- the device comprises three chambers K.1-3 and three deflection elements U.1-3. No thread deflection takes place at the entrance to the first chamber K.1 in the thread running direction.
- the device consists of two parts 30.1 and 30.2, of which the block part 30.1 is preferably fastened to a device frame, while the cover part 30.2 can be opened by means of, for example, a closure and hinges relative to the block part 30.1, so that the threads can be carried out.
- the functions of the two parts 30.1 and 30.2 with respect to the method according to the invention are the same.
- the plane that separates the two parts 30.1 and 30.2 of the device is the one in which all the threads entering and leaving the device lie.
- FIG. 3 shows this embodiment of the device according to the invention as a section through both device parts 30.1 and 30.2 perpendicular to the plane that separates the two parts and parallel to the thread running direction.
- the threads run into the first chamber K.1 through an inlet slot 31.1 which is perpendicular to the cutting plane and out of the third chamber K.3 through a corresponding outlet slot 31.2.
- One of the threads is shown in FIG. 3, entering the device as a wetted thread F.1 and exiting the device as a dry thread F.2.
- the three chambers K.1-3 which consist of two identically shaped chamber halves falling in the direction of gravity away from the thread path, one of which is located in the block section 30.1 and one in the cover section 30.2, are closed off from the outside by the outer walls of the two device parts and through the chamber partitions 32.1-4 separated from each other.
- the chamber partitions are shifted against each other in such a way that they follow one another in the thread running direction in the following sequence: 32.1, 32.2, 32.4, 32.3, 34.1, 34.2.
- the latter two are not actually chamber partitions, but the thread outer side chamber walls.
- the partitions 32.1-4 are designed in such a way that, when the two device parts 30.1 and 30.2 are adjacent to one another, they leave a gap S.1 and S.2 open for the threads running through, the width of which corresponds to 2 to 10 times the fibril diameter.
- three thread deflection elements U.1-3 are attached to corresponding ledges in such a way that they protrude a little beyond the plane that separates the two device parts 30.1 and 30.2, and thus the threads from their rectilinear movement in this plane between the entry slot 31.1 and deflect the outlet slot 31.2.
- the deflection elements U.1-3 are preferably ceramic rods with a sliding-friendly surface. In a device such as that shown in FIG.
- the chamber K.1 is connected to the chamber K.2 with, for example, four passages (35.1 and 35.2 in FIG. 3, 35.1 and 35.3 in FIG. 4), which advantageously start from the lowest points in the chamber in the direction of gravity.
- the same passages 35.5-8 connect the chamber K.2 with the chamber K.3.
- the chamber K.3 is connected, for example with two passages 36.1 and 36.2 through the chamber outer wall, which advantageously open into the chamber K.3 at the lowest chamber locations and which have the same angle of inclination as the chamber itself, with a suction device.
- Figure 4 shows a detail of a top view of the inside of the block part 30.1 in the area of the chamber K.1. The course of the thread between the separating bars 37.1-5 and over the deflecting element U.1 can be seen from this.
- FIG. 5 shows a detail of another exemplary device variant with adjustable chamber wall parts.
- the chamber wall parts can be moved relative to the plane of separation of the two chamber parts. Not only the deflection angle ⁇ of each process sub-step, but also the width of each individual gap S can thus be varied with an arrangement with all chamber wall parts of the same design and the same deflection elements.
- An exemplary application for this device is the dosing of spin finish.
- the thread is first impregnated with an excess of spinning finish and then subjected to the process according to the invention with process parameters set in such a way (deflection angle ⁇ , gap width S, negative pressure) that it contains the desired amount of spinning finish when it leaves the device according to the invention.
- FIG. 5 shows an exemplary embodiment variant for the adjustable chamber wall parts.
- Both chamber wall parts 51.1 and 51.2 are not firmly connected to the chamber outer walls 50 of the device, but are guided in them and adjustable with the aid of, for example, adjusting screws 52.1 and 52.2.
- a spring 53 is attached between the chamber wall part and the chamber outer wall, which presses the chamber wall part in its possible position that is furthest away from the chamber outer wall.
- An adjustment of the chamber wall part 51.1 which carries the deflection element U, primarily causes an adjustment of the deflection angle ⁇ .
- An adjustment of the chamber wall part 51.2 relative to the position of the chamber wall part 51.1 given by the deflection angle causes an adjustment of the width of the gap S, which is adjustable, for example, between 0.05 and 0.1 mm.
- FIG. 6 shows a further exemplary embodiment variant for the device for removing liquid from high-speed threads. It corresponds to the devices of Figures 2 and 3 in terms of their function and also in terms of their basic structure. It differs from the previously described design variants by the design of the chamber partition walls 60.1 / 2/3/4, which are designed in such a way that the chambers enclosing the thread are smaller and, above all, the angle ⁇ between gravity and the part of the liquid leading away Chamber walls 61.1 / 2/3/4 (discharge elements) is smaller.
- the angle ⁇ is advantageously chosen between 10 ° and 60 °.
- the width of the channel 62.1 and 62.2 leading away from the chambers such that the free fall height for the drops is small. It has been shown that the width of the channel at its entrance into the chamber is advantageously chosen between 0.5 and 5 mm.
- the chamber walls according to FIG. 6 can be equipped with separate deflection elements, or else they can be formed from a suitable material such as sintered oxides, for example aluminum oxide, in such a way that they can be used in one piece as a chamber partition, discharge element and deflection element. They can be adjustable transversely to the thread running direction in the manner shown in FIG. So that the effect of the device can be adjusted for a specific application.
- a suitable material such as sintered oxides, for example aluminum oxide
- the local flow formed by the separation of air in the chambers forms a vortex, which impacts finer liquid particles (droplets) on the chamber walls and can thus be excreted so that the portion of the current flowing back onto the thread contains less liquid than the part leading away from the thread. This creates a dynamic balance that is aligned with the process.
- the contact surfaces of the two main parts can be designed in such a way that they are not flat in the open state (without any force acting on them) and only deform in the closed state (under the action of the forces of the closing means) in such a way that they form a metallic sealing connection.
- Corresponding sealing surfaces are in CH registration no. 4496/89 by the same registrant.
