Method and device for producing continuous filaments and / or staple fibers from thermoplastic material.

The invention relates to a method for producing continuous filaments and / or of staple fibers made of spinnable thermoplastic

Material in which the spun threads are withdrawn from the spinnerets at a high speed. The invention i relates to an apparatus for performing the method.

For the production of filaments and staple fibers from spinnable thermoplastics, such as. B. polyesters, polyamides and polyolefins, a melt of the thermoplastic material is pressed through spinnerets, the threads, which solidify when blown with air, are pulled off and wound up. The wound threads are then unwound again, combined to form a cable, stretched and, if staple fibers are to be produced, crimped and cut to the desired length, the so-called stack. Because of the different working speeds during spinning, drawing and cutting, the spinning process is separated from the subsequent processing. Instead of first winding the spun threads onto bobbins, it is also known in staple fiber production to first deposit the spun material in cans. Spinning cans are open-topped containers that can hold splinting quantities of 200 kg and more. The depositing of the spun material in cans only allows thread speeds of around 1,000 m / min.

When the threads are wound onto bobbins, higher thread speeds of, for example, 1,500 m / min and above can be achieved. In order to be able to properly unwind the wound threads in the creel from the bobbins again, it is necessary, however, to apply a so-called preparation agent to the threads before winding. The preparation agent is generally a liquid mixture of lubricants, emulators, wetting agents, antistatic agents, oils, etc. The preparation agent applied to the thread can be up to 2 <fo the thread weight.

In all of the previously known methods, there is a safe thread deposit not at high thread speeds of over 1,500 m / min possible.

It has now been found that it is possible in a simple '/' way to use to safely deposit threads made of thermoplastic material spun at high speed without the use of spin finish agents, that they are further processed without difficulty at a low speed, for example wound, or crimped and into staple fibers can be cut.

The method according to the invention allows withdrawal speeds of the spun threads of up to 7,000 m / min and higher. The thread withdrawal speed can be increased until the threads tear when pulled. According to the present invention, the

009885/1804

With a high thread speed, ie at speeds over 1,500 m / min, drawn threads are deposited on a continuous finite tape with a back and forth movement transversely to the direction of travel of the finite tape and wound up with the finite tape to form a roll. The deposited fiber material can then be removed from the wound roll when the roll is unwound at low speed and fed to further processing. The depositing operation on the normally continuous with uniform velocity finite band is for example shown schematically in Figure 1 (in a perspective view. The flat, i finite band is numbered 1. It is handled in the illustrated operation of the left roller 2 and moves at constant speed in the direction of the arrow to the right and is rolled up to the roll 3. Designated with 4 is an endless thread made of thermoplastic material, which is drawn off from a device (not shown) at high speed, ie at a speed of over 1,500 m / min and which accordingly strikes the moving belt 1 at the same speed.

i according to the endless thread 4 on the belt 1 with a back and forth

i moving component transverse to the running direction of the belt 1 filed. In order to achieve this back and forth movement component transversely to the running direction of the belt, either the endless thread 4 can be set in a reciprocating motion or the running belt 1 can be made to perform lateral / tus pivoting motions. Both options can also be used at the same time. In the figure 1 is indicated by the dashed lines 5 and 6, that the endless thread 4 is set in a reciprocating motion below the point 7 and is between the two

009885/1804

extreme swings 5 and 6 back and forth. The device device that generates the reciprocating movement is not shown in the schematic Figure 1. When hitting the running belt, the endless thread is deposited in a path of overlapping thread curves, as shown schematically and for example at 8 and 9 is indicated. When moving the onto the belt with high G-es speed on the hitting thread is first transverse to the direction of travel of the tape a strip of tangled, d. H. irregular-) moderately overlapping thread curves of the endless thread fin to which fc tape filed. The formation of confused, d. H. irregularly intersecting thread curves is a consequence of the high take-off and Deposition speed of the continuous thread 4. During the backward movement following the outward movement, transverse to the running direction of the belt 1 Another strip of tangled thread curves of the continuous thread is placed on the belt. Because the tape is under the thread deposit point moved through, the consecutively deposited strips of the thread curves of the continuous thread do not come to lie completely on top of one another. gen, but are somewhat shifted against each other according to the running speed of the belt. Because of the running speed of the Tape 1, the strips are not deposited exactly at an angle of 90 ° to the direction of travel of the tape, even if the back and moving the thread between the extreme positions 5 and 6 in one Plane takes place which forms an angle of 90 ° to the direction of movement of the tape. However, it is not necessary that the plane fixed by the extreme positions 5 and 6 forms an exact angle of 90 with the direction of travel of the belt. Important is rather, that the thread impinging on the running belt is a reciprocating motion with a component of motion transverse to

009885/1804

the direction of travel of the belt. To a high weight of filed To achieve thread material per unit area of the depositing belt 1, the speed of the belt is chosen so low that that the discarded adjacent strips of the thread curves partially overlap. The thread material deposited in this way on the belt can be the in the back and forth movements of the The stripes of the thread curves deposited one after the other can generally no longer be recognized without a detailed examination. With thread take-off and thread laying speeds above 1,500 m / min, the speed of the belt 1 only needs about 1 to 10 m / min be. The thread course 8 or 9 deposited on the tape 1 is rolled into the tape to form the roll 3.

In FIG. 1, the course 10 of a deposited thread is also indicated, for the sake of better understanding would be obtained if the tape 1 were moved at a speed which is approximately as great as the withdrawal speed of the thread. This thread course 10 would be one Correspond to the sine curve. In practice, this form of deposit could only be used at low, and therefore uneconomical, take-off speeds of the thermoplastic thread. In addition, the weight of the filament material deposited per unit area would be much too high low, so that the filing of continuous threads in sinusoidal curves according to number 10 is of no interest in practice.

The method according to the invention not only allows the filing and storage of a single endless thread on the tape. Ea is erfindungBgemäß AUOH possible to deposit on the finite band two or more filaments in the beüuhriebenen manner in adjacent tracks, as shown for example in Figure 2 sohematiach

009885/1804

is shown. FIG. 2 shows a plan view of a band section 11, on which three webs 12 of tangled thread curves placed next to one another are shown. According to the method according to the invention, however, one or more thread bundles lying next to one another can also be deposited on the running finite tape in the manner described and then rolled into the finite tape for storage. A thread bundle is understood to mean several combined individual threads. It is possible, for example, about 10 to summarize ψ 600 individual filaments into a filament bundle. The thread bundle withdrawn at high speed is deposited on the finite belt, which continues at a uniform speed, with a component of movement transverse to the running direction of the belt. The laying process of a thread bundle corresponds to the laying process shown schematically in FIG. 1 when 4 is not a single thread but a thread bundle made up of several individual threads. Of course, it is also possible to place several thread bundles next to one another on a moving belt. If, for example, three thread bundles are deposited next to one another on a moving belt, the result is a picture similar to that in FIG. 2, only then 12 no longer denote the curved paths of a thread, but the curved paths of a thread bundle. The thread curves of the individual continuous threads lie confusedly together in the laid tracks.

Due to the low running speed of the tape of a few meters per minute (approx. 1 to 10 m / min), it is possible without difficulty to wind the tape together with the thread material stored in thread curves into a roll. The finite belt, which does not move at a constant speed, can have a length of up to 200 m, for example. In praxia they don't have bandwidths from about 1 to

009885/1804

3 m iJEKtte and lengths from 50 "to 200 m proven. On the tape you can depending on the titer of the filaments, the take-off speed and the belt speed Approx. 600 to 1,200 g of thread material per square meter of tape surface are deposited and then rolled up. In the In most cases, 800 to 1,000 g of thread material can be deposited and rolled up per square meter of tape surface. A y / achsel's Because of the low running speed, there is no tape either Difficulties and with practically no loss of filament material possible.

It is extremely surprising that the filament material deposited and stored in a tangled form from the wound rolls of tape -when unwinding the tape rolls again perfectly and without thread breaks or knots and loops in the form of continuous threads can be removed at a speed that can be technically mastered without difficulty and that of the subsequent processing the thread material (z. B. winding or crimping and cutting) is adapted.

When carrying out the method according to the invention, it has proven advantageous to use blow nozzles to the threads or thread bundles that work on the ejector principle. The threads will passed through the nozzle, in which it is captured by a relaxing gaseous or vaporous blowing medium and at high speed pulled off, stretched and deposited on the running belt. Air is generally used as the blowing medium. To high Thread withdrawal speeds of over 1,500 m / min, preferably from 2,500 to 5,000 m / min, can be achieved within a blow nozzle Flow velocities of the blowing medium from about 200 to 800 m / s

necessary. According to the method according to the invention upon impact of the thread material on the continuous belt required speed component transverse to the direction of the moving belt can be produced when using blow nozzles as a draw-off and stretching device, for example, that the blow nozzles are lateral Perform swivel movements. It is also possible not to move the blower nozzles themselves and at the lower end of a blower nozzle to arrange or mount a movable set of ports, the lateral Swiveling or reciprocating movements.

^ When using air nozzles as a take-off and stretching device the blowing medium hits the continuous, finite belt together with the threads. So that the thread material deposited on the running belt is not blown away or confused by the blowing medium, the finite band must be permeable to the blowing medium. It is beneficial if a suction device for sucking off the blowing medium is attached under the belt below the thread deposit. Farther it has proven to be useful to remove the Do not inflate continuous filaments directly on the running belt, but on a concave curved surface that is transverse to the running direction

' of the tape is almost or completely seated on the tape. The easiest way to use the surface of a cylinder as the concave curved surface is the surface of a cylinder. For this purpose, a V-fold approx. 15 to 100 cm in diameter is allowed to sit on the belt so that the roller rotates according to the belt speed. When the filaments and the

As the blowing agent stream hits the concave surface area, both the blowing agent and the continuous filaments bounce off the concave surface. The filaments are then in front of and below the concave surface

009885/1804 _ _g _

stored on the running belt in thread curves. The concave face or the roller prevents the threads that have been laid down from being whirled up again by the stream of blowing agent.

A device for carrying out the method according to the invention using a blower nozzle as an extraction device is for example and schematic]! shown in Figure 3.

The device consists essentially of the two parallel rollers 20 and 21, over which an endless air-permeable belt 22 rotates. The roller 20 is driven in the direction of the arrow by the drive device 23, for example a motor. The direction of movement of the endless belt ⁴ 2 is also indicated by arrows. The endless belt 22 can for example consist of a coarse-meshed wire mesh. The distance between the two rollers 20 and 21 is 2 to 5 m, for example. The finite belt 24 is unwound from the right roll 25 and transported to the left by the conveyor belt 22 and wound up there to the j roll 26. The rollers 25 and 26 and the finite deposit belt 24 lie directly on the conveyor belt 22. The deposit belt 24 must also be permeable to air. A glass filter fabric with mesh openings of 6x6 mm, for example, has proven itself as a storage belt. The threads of the glass filter fabric can be coated with a suitable plastic, for example with polyvinyl chloride. Instead of a glass filter fabric, however, other suitable coarse-meshed and air-permeable fabrics, for example polyester, can also be used

monfil, can be used as a storage belt 24. Below the thread rest the suction box 27 is arranged just below the conveyor belt 22. It is open at the top to allow air to pass through the thread holder sucked through the deposit belt 24 and the conveyor belt 22. The suction box 27 is connected to the suction line 28, which leads to a fan, an induced draft fan or another suction device, not shown. Between the suction box 27 and of the driven roller 20, the counter-pressure roller 29 is located just behind the suction box. The counter-pressure roller 29 presses against the roller 30, which rests on the upper side of the depositing belt 24 and which has a diameter of 15 to 100 cm. The surface of the roller 30 forms the concavely curved surface onto which the filaments to be deposited are inflated.

The device shown serves to generate the continuous filaments the spinning extruder 31, designed in a known manner, into which the thermoplastic material to be spun is fed through 32 is added. In the spinning extruder, the melted thermoplastic material is conveyed to the spinning nozzle 33 and through the openings of the spinneret 33 are pressed. The spinning nozzle 33 can have up to 600 or more spinning orifices. That the spinneret The exiting thread bundle is numbered 34 and is guided through the blow nozzle 35. The blower nozzle 35 works on the ejector principle. The blowing medium, generally air, is introduced through the feed 36 into the blowing nozzle 35 and expanded in the blowing nozzle. As a result, the blowing medium in the blowing nozzle 35 reaches high flow speeds of approx. 200 to 800 m / 3. By the high The flow velocity of the blowing medium is the thread bundle,. · Ί 34

withdrawn at a high speed of over 1,500 m / min, preferably 2,500 "to 5,000 m / min, and at the same time stretched. The extension pipe 37 is attached to the lower end of the blow nozzle 35 by means of the movable connection 38 (e.g. rubber hose). That Extension pipe 37 is from the horizontally reciprocating Rod 39 set in an oscillating motion. The rod 39 can, for. B. be a connecting rod. The reciprocating movement of the Rod 39 takes place at an angle of 90 to the direction of movement both bands 22 and 24 · The one from port set 37 together with the j The yarn bundle exiting relaxed blowing agent flow moves back and forth between the extreme swings 40 and 41 hits the roller 30 as it moves back and forth approximately along the line 42. The blowing agent stream hitting the roller and the filaments bounce off the roller surface and meet the moving deposit belt 24 in front of and below the roller 30 on. The deposit zone on the belt 24 is numbered 43. The filaments have a speed component when they are deposited on the deposit belt 24 Qoier to the running direction of the deposit belt 24, which is due to the reciprocating movement of the rod 39. The blowing agent flow impinging on the depositing zone 43 is through the deposit belt 24 and through the conveyor belt 22, which carries and moves the deposit belt 24, into the suction box 27 below the storage zone 43 and from there via the suction line 28 to the

In FIG. 4, the cross section through the thread deposit of the device shown in FIG. 3 is shown. The individual parts are numbered as in Figure 3. That coming from the air nozzle and moving back and forth in the direction of the viewer The moving thread bundle 34 meets the Y / alze at the point 42 30 on. The course of the threads between the point of impact 42 and the deposit belt 24 is shown schematically in FIG. The point of impact 42 is generally chosen so that the connecting line between the point of impact 42 and the roller center M with the perpendicular roll diameter H-H 'an angle ^ from approx. 25 to 30 forms. However, it is also possible to direct the thread bundles coming from one or more blower nozzles in front of the roller 30 or a concavely curved jacket surface 30a to impinge on the belt 24, as shown schematically in FIG Cross-section is shown in FIG. In general, however, this does not achieve as good a thread deposit as when you use the Threads can impinge on a concave curved surface that is arranged transversely to the direction of movement of the depositing belt 24. It has been found that it can achieve a particularly good Thread deposit is advantageous if the axis of the roller 30 or that of the concavely curved lateral surface coincides with the running direction of the belts 24 and 22 do not form an exact right angle, but an angle of approx. 95 to 105 °. Such an arrangement is for example and shown schematically in FIG. The representation corresponds to that in FIG. 3. Parts with the same functions are denoted by the same numbers. In contrast to the device shown in Figure 3, the roller 30 is arranged so that

In contrast to the device 3, three blow nozzles 35 are arranged above the roller 30 in the device of FIG lateral pivoting movements of the reciprocating rod 39V be moved. Move the thread bundle emerging from each nozzle 35 or from each extension tube 37 and the flow of blowing agent to and fro between the extreme positions 40 and 41 and meet the rotating roller 30 approximately along the lines 42 on. At the deposit zone, the blowing agent flows are passed through the deposit and conveyor belt sucked into the suction box 27. The three bundles of continuous filaments are in three side by side Tracks 44 in overlapping thread curves on the deposit belt filed and rolled up together with the filing tape to form the roll 26. (The actual spinning devices are not in Figure 6 shown.)

If the continuous threads impinging on the running belt are to receive the reciprocating movement component transversely to the running direction of the depositing belt alone or additionally by the depositing belt executing lateral pivoting movements, then the rollers 21 and 22 are expediently in the devices shown in Figures 3 and 6 Arranged on a common base, which can move back and forth horizontally with the said storage device.

In a reciprocate reciprocating storage device has the suction box, if such is present in the use of blowing nozzles as a deduction device, to be connected to a mobile \ ^r Getting Connected line 28 to the suction device. A hose line can be used as a movable connection line.

When in the devices of Figures 3 and 6, the roll 25 of the deposit tape is unwound, a new roll 25 is directly behind the unrolled deposit belt is placed on the running conveyor belt 22. There is no interruption of the filing process necessary.

As soon as the entire length of the storage tape 24 is wound into the roll 26 is, the still outstanding webs of the continuous threads are cut and the finished wound roll 26 from Conveyor belt 22 removed. The beginning of the new filing belt closes immediately together with the thread material that has already been placed the beginning of a new roll 26 wound.

The cable 52 is fed via the pulley 53 to the mechanical pull-off device 54, which pulls the cable 52 off, for example at speeds of approximately 20 to 100 m / min. The cable 52 is fed to the cutting device 56, in which it is desired on the overall {stack is cut. The cut fibers fall i onto the conveyor belt 57 and are fed by it for further use.

In the case of polyolefins in particular, it is because of the risk of sintering or melting the thermoplastic material when cutting, wet cutting to the desired stack length, the means to be carried out with the addition of water. Suitable for this Commercial devices. For example, a commercially available cutting machine can be used in which the cable from I sucked in a Viasserstrom and fed to the rotating cutting knives i. The cut staple fibers fall into a Alluvial trough and are fed from there for further use. Wet cutting into staple fibers is also special then advantageous if the staple fiber-water mixture is added to a paper pulp to increase the tear strength of the finished paper or a fleece is to be produced from the staple fiber / water mixture on a paper machine or a similar device.

The mixture of water and Staple fibers can then be used directly in paper processing or for the manufacture of nonwovens.

If desired, crimping can also be carried out in a manner known per se prior to cutting.

The thread material deposited in the coiled rolls of the filing belts can also be drawn off at low speed when unwinding the rolls in the form of endless threads and as endless threads or combined into cables wound onto spools or processed in some other way.

The inventive method allows a simple and cheap Intermediate storage of the spun at high take-off speed Continuous filaments made of thermoplastic material and thereby also an economical spinning and an economical production of Staple fibers. It is not necessary to use preparation agents or lubricants in the method according to the invention. at t the spinning of polypropylene, polyamides and polyesters generally a titer of the individual threads or fibers of 1 to 30 den and a tensile strength of 2 to 7 g / den achieved.
