Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to the production and processing of man-made fiber yarns, such as post-processing using looms, twisting machines, spindle winding machines, orthogonal non-woven fabric machines, etc. It is possible to manufacture and manufacture dozens or even hundreds of rolls in parallel without winding them around a core.
This is an invention related to an innovative technology that does not use a core at all, which shortens the process compared to conventional methods, saves labor and energy, and significantly reduces the cost of making cloth. be.

Relationship with prior art 1 In the earlier application, Japanese Patent Publication No. Sho 59-5693, the present inventors did not handle yarns individually, but lined them up in large numbers and applied them to a push-crimping machine, and then placed them in a push-in box. By making it into a crimped string, the moving speed of the V1 yarn is reduced by an order of magnitude, and the crimped string discharged from the outlet of the push box is continuously wrapped in a covering material, and is taken up under the tension of the covering material. The application was filed for a method in which the yarn is cut into predetermined unit lengths, brought to another processing step, the coated crimped cord is pulled out and uncoated, and the yarn is divided into individual threads directly in post-processing.

One feature of the method of this application is that the discharge crimping cord is transferred to another post-processing step in the form of a package that is wound onto a winding core while being covered with a covering material. However, when using this method, the present inventors are unable to avoid the fact that the packaging is bulky because of the covering material, and the packaging costs also tend to be high. After repeated experiments, we found that even without using a covering material, if the crimped yarn bundle is shaken in a zigzag pattern into a packing box, such as a cardboard box, and folded and stored, it can be transported in the same way as packing and transporting filament tow. This is what the present invention has achieved. 2. In addition, the novelty of the present application is listed as compared to Japanese Patent Publication No. 47-47549 (Patent No. 697100), which is an earlier invention of the present applicant.

This application is directly connected to the yarn manufacturing process, and is characterized in that when the yarn manufacturing process is particularly high-speed, the yarn length is folded and the speed is reduced by an order of magnitude to be taken out. It is characterized by the fact that a large number of yarns produced in parallel are bundled into crimped yarns, the speed is reduced by an order of magnitude, the speed is lowered by orders of magnitude, the speed is reduced, and the process is packaged and shipped in large quantities (for example, 100 kg or more). Pressure steam fixation is not necessarily a necessary condition, steam heating is merely for temporary stabilization of crimping strain, and this invention differs from the prior invention in that this purpose can be achieved by atmospheric pressure steam treatment up to 100°C.

The two applications are directly connected to yarn production and are applied to high-speed spinning of several hundred meters per minute or more, and bring about particularly remarkable effects, but Patent No. 69
When No. 7100 is applied to yarn, it is difficult to increase the speed because it is directly connected to winding the divided yarn after crimping and fixing.

In this application, the split threads are directly connected to the post-processing process, so
This goal can be achieved with easy-to-work, low-speed separation. 3 In the present application, the bundle of crimped yarn is often boxed and shipped as is, and it is only necessary to wrap it with an air-permeable covering material during the process of pressure vapor fixing the crimping.

4. The application is to short-circuit the entire process of yarn manufacturing and processing;
This is an invention related to rationalization of labor saving and energy saving.
No. 97100 is an invention related to a partial processing technique called crimping and fixing.

3. Conventionally, multifilament yarns have been used for clothing.

Multifilament yarn is made up of many parallel filaments (long fibers) discharged from a porous spinneret, so if the yarn is charged during handling, it can cause yarn cracking, fluffing, and yarn breakage. Nylon, polyester, etc. are heated and bonded using a stretching machine and wound up using a single pot motor, so yarns are sold individually wound around cores, and in textile factories, even for woven fabrics that do not require heating. The fabric is woven by warping a large number of yarns that are let out one by one from a creel. Handling each thread individually due to heating requires a lot of labor and is a cause of high cost on the thread manufacturer's side as well as on the weaving fabric side.

In addition to heating, multifilament fibers can be conjugated using glue, similar to raw silk, but this method is not generally used at present.

Summary of the invention 1 Regarding the thread.

The inventors of the present invention have discovered that another method for improving the binding properties of multifilament yarns is the winding binding property of the yarn. For untwisted or nearly untwisted multifilament yarn,
When the fibers are crimped in an appropriate manner, the crimped single fibers are entangled and bound together, and the yarn does not break even when charged. When a large number of untwisted multifilament yarns are lined up closely and run through a push-crimping machine, the filaments of one yarn seem to get entangled with the filaments of other yarns, but try separating them. It was discovered that the threads could be separated from other threads without any problems, probably because of the strong intertwining between filaments of the same type. In particular, it has been found that when heated with live steam, static electricity is prevented in the presence of moisture, and when heated above the secondary transition point, the thread becomes flexible, so it can be divided into threads without any problems. This was one of the reasons for the launch. 2 Parallel order of threads.

If the push box attached to the push crimper has a constant height in the width direction, it will be guided. If the threads are passed evenly between the diagonal combs (with a certain number of threads stacked between the combs of a certain pitch), the order of the threads bitten by the pushing roller will be completely constant, and the length direction will be folded and crimped. The experimental results also confirmed that there was no disturbance in the parallel order of the yarns in the pusher box, and that the division of the curled yarn bundle was very smooth. 3.1 Relationship between yarn feeding speed and yarn discharge speed.

The advantage of using a push-crimping machine to fold the yarn bundle in the length direction to create a crimped yarn bundle is that the yarn feeding speed is orders of magnitude slower than the yarn feeding speed, and the crimped yarn bundle can be produced from the outlet of the push-in box. Exhaust 1. To be discharged. The crimped yarn bundle is discharged to the exit side when the total cross-sectional area of the fibers is in the range of 25 to 40% of the inside cross-sectional area of the push box, so if the number of yarns is constant, for example, 100 to 150 d
The finer the denier yarn, the smaller the overall denier, and the discharge speed of the 2 yarn bundles is 1/50 to 1/1 of the yarn feeding speed.
Even if the same push box is used and the overall denier is large, with a thick count of about 1000 d, the bundle of crimped yarn is discharged at a slow speed of about 1/15 to 1/20. This order of magnitude reduction in speed is even slower as the height of the pusher box increases, but it is an advantage that makes it extremely easy to take out high-speed parallel yarn as a bundle of curled yarn. That is, the drawing and post-processing speed of parallel yarns is 150
→As the speed increases to 300 m/kg, the cost of the three spindle winding machines will be high if each thread is handled individually. If the yarn is bundled, the speed will be reduced by an order of magnitude, and it will be easy to pack the thickened bundle of curled yarn into boxes and to store and pack large quantities of 100 kg or more even if the yarn is wound up. 33.2 Number of threads.

In the present application, "multiple yarn bundles" refers to the fact that the bundle of curled yarn taken by the method of the present invention is directly connected to a twisting machine, spindle winding machine, warping machine, loom, orthogonal nonwoven fabric machine, etc., and divided into yarns in post-processing. The number of yarns matched to the number of spindles, that is, in many cases, 150 to 200 yarns are arranged in four rows in parallel, or twice the number of yarns in parallel are connected directly to two twisting machines. When directly connected to a loom or an orthogonal non-woven fabric machine to split the yarn, in order to adjust the number of yarns, a large number of curled yarn bundles are divided in parallel and warped to a predetermined width and yarn density to produce fabric.

3.3 Thread separation speed.

Splitting the threads directly in post-processing is easy because the splitting speed can be slow. For example, when directly connected to a multi-spindle twisting machine, even if the spindle rotates 10,000 revolutions per hour, if the twist is 250 T/m, the yarn should be divided at 40 m/Wm), and if it is 500 T/m, the yarn may be divided at 20 m/Wm. If the twist v is 1000 T/m or more with fine count yarn, the speed will be even lower. In the case of a non-twisted woven fabric, if it is directly connected to a loom, the threads can be divided at 0.5 to 5 m/Wt. Even with an orthogonal non-woven fabric machine, the threads can be split at a rate of 40 to 50 m/Wt in both the warp and weft. In such low-speed work, even if there is a broken or missing thread, the dropper can detect it and replenish the replacement thread, allowing the work to continue without stopping. 3.4 Yarn packaging unit and floor area.

In any case, even if the packaging unit is 100 kg, there is no need for a large floor area to store the creel, and the unwound bundle of crimped yarn is blown with live steam in a vertical position, or the yarn absorbs moisture. If the crimped material is in contact with the heated wall, the crimped material is stretched out while being subjected to friction on the zigzag-arranged heating guide rod, and is separated through a comb while being protected from static electricity by moisture.
If it is warped to a fixed pitch and width and then guided through a pinch roller to a twisting machine, a spindle winder, a loom, or an orthogonal non-woven fabric machine, it is far more effective than warping that requires a conventional creel. Warping can be done in a narrow floor space. In other words, there is a great advantage in that a bundle of curled yarn can be worked on by occupying an order of magnitude smaller space than when handling a single yarn. 3.5 Stability of crimping.

If we want to obtain a crimped yarn that has permanence in its crimping, that is, even if the crimped yarn is stretched during the processing process, it will return to its original shape when heated in a non-tensioned state. Patent No. 6
Using the continuous pressure steam fixing method of crimped fibers of No. 97100,
The crimped yarn bundle discharged from the push box is wrapped in a breathable covering material and subjected to an additional continuous pressure steam treatment process, and after removing the covering, it is cut into predetermined lengths and packed and shipped. 3.6 Regarding industrial materials.

The above description has been about multifilament yarns for clothing, but let us consider the case where the present invention is applied to polyolefin flat yarns, split yarns, monofilaments, etc., which are mainly used as industrial materials. Since none of these are multifilament yarns, there is no need for heat binding. Therefore, it is a yarn that does not need to be handled as a single yarn, and even though it is produced by drawing several yarns in parallel, it follows the custom of conventional spun yarns and multifilament yarns, and only one yarn is used on the winding core. It is shipped in this volume, and then woven at a weaving factory through manual warping using a creel. Low cost is a necessary condition for expanding the use of industrial fabrics, and the field that should be streamlined by applying the present application is first of all the field of polyolefin yarns. Currently, the production speed of polyolefin flat yarn, monofilament, etc. is 150 to 160 m/'11i.
! It's about 65-90m7! A small extruder with a diameter of L is used, and the production volume of one line is 1 to 2 tons/day, making it suitable for a small business. This is because changing the winding core at too high a speed would make it impossible to do it manually. Even for clothing fibers today, the spinning speed of nylon and polyester is over 1000 m/Wt, and if post-stretching is included, it is 4000-5000 m/W.
t is the capacity of one spindle. If the water-cooling method is used to form a polyolefin tubular membrane, the width will be 2 m and the thickness will be 0.0611 mm!
50-60m/7 with membrane! Possible to form S film, width 2m
If you stack two membranes, slit them to 20 thread widths, and stretch them 9 times, 200 1000 d flat yarns will become 400~500 strands.
Produced by m/Rllt.

In this case, if the present application is applied, the take-up speed of the curled yarn bundle can be increased to 10
It is easy to achieve ~20m/WL, and the production capacity of the Vll series is about 15 tons per day, which is the production technology of a large company.
If 4 sets of curled yarn bundles consisting of 00 yarns are arranged in parallel and divided, 10
It is possible to warp cloth with a width of book/inch x 2m. This shortens the process of making woven fabrics and orthogonal nonwoven fabrics, and saves labor, resulting in a significant reduction in costs. In addition, for orthogonal nonwoven fabrics, if a stretched membrane with the same width as the roller width of a force crimping machine is made and many sheets are stacked and crimped to form a crimped string, the number of warps can be reduced by an order of magnitude. This can be done directly in conjunction with post-processing. 3.7 Advantages of the present method.

If the textile industry no longer had to deal with the number of kilograms of yarn per unit, that is, the work of handling one yarn in units of 100 kg or hundreds of yarns, the textile industry would change from a light industry that required labor to an equipment industry that did not require labor. The cost of D1 fabric is significantly reduced. I am not aware of any examples of conventional crimping on flat yarns.

However, although the purpose of the crimping according to the present application is to reduce the speed of high-speed spinning by an order of magnitude, the fact that some crimping remains even in flat yarns may affect the fabric's bulkiness and drape. It has improved properties and an anti-slip effect when making bags, so even though it has advantages that were not available before, it does not have any disadvantages. This point also applies to clothing fibers.
In many cases, woven fabrics made of straight-stretched yarns are desired, as well as fabrics made of yarns with some degree of D crimp. The feature of the present application is that the push-crimping method, which has been mainly used for filament tow, which is a raw material for spinning, has been found to be advantageous in relation to all processes of yarn production and processing.

If the crimped yarn bundle of the present application is taken and manufactured in the same factory, the storage container for the crimped yarn bundle and the length of the yarn bundle can be selected arbitrarily, but the crimped yarn made by the yarn manufacturer If the bundle is sent to another processing factory for processing, it is desirable to ship it from the yarn manufacturer in fixed quantity or fixed length packaging.

This dot-wound bundle of shrunken yarn is stored in a storage box after being folded in a zigzag fashion from front to back, left to right, and then compressed in the height direction and packaged like cotton packaging, or compressed and packaged in a cardboard box and shipped. Alternatively, the bundle of crimped yarn is wrapped in a covering material such as breathable fabric, and the crimped yarn is fixed with continuous pressure steam, then uncoated, cut into predetermined lengths, and shipped. Conventionally, there has been no product type in which a bundle of curled yarn of multi-filament parallel yarn is shipped as a packaged product weighing, for example, 100 kg or more.

The feature of the present application is that this is made practically possible.
When the bundle of curled yarn discharged at a constant speed from the push box is taken forward and stored in the packing box, the shape of the bundle of curled yarn is maintained and stored in accordance with the discharge speed. However, this is not an absolute requirement, and as long as no tension is applied to the outlet of the push box, it is possible to quickly pull it back and store it in a way that the crimping is slightly stretched.

Detailed description of the application with illustrations.

FIG. 1 shows a cross section of an example of a push-in crimping machine.

In order to sufficiently strengthen the pushing force for multi-filament parallel yarns, and to flatten the parallel yarns that have been spread out over a wide width and then post-processed to the width of the pushing roller in an orderly manner and have an even thickness, in many cases, upper and lower two groups 1 and 1 are used.
In many cases, a fixed number of combs are passed between the combs 2 and 2', which are divided into combs 2 and 2', and are supplied to the push rollers 4 and 4' via guide rollers 3 and 3' in a form with a large contact area. The fibers are softened by steam injection and the frictional force is increased due to moisture absorption, and the fibers are pressed and pushed into the pushing box 5 having a rectangular cross section. As another method of blowing steam, as shown in the figure, pressure steam chambers 6, 6' are provided on the upper and lower walls of the push box, and tubes T, . The pressurized steam sent through T' is injected from the tip of the pushing box in the opposite direction to the rotation of the pushing roller, and its peeling effect prevents the fibers from being bitten between the roller and the tip of the pushing box. To prevent. At this time, the steam leaking from the tip of the box along the rollers in the direction of roller rotation increases the contact area of the walls 8, 8' with the rollers to minimize leakage. Although not shown inside the side plate 9 of the pushing roller, pressurized steam is injected inward at the contact point 10 of the upper and lower pushing rollers to prevent friction with the side surface of the fiber. The pressurized steam injected into the push box is
It passes through the curled yarn bundle and leaks into the outside air through the push box outlet 11.

The bundle of curled yarn discharged from the outlet 11 is then circulated by guide rollers 12, 12', 13, 13' between the upper and lower 2
Sandwiched between two sandwich belts 14 and 15,
The flat bundle of crimped yarn substantially maintains its shape immediately after being discharged from the pusher box, is transferred diagonally upward, and is shaken off by traversing a fixed width back and forth from the tip of the transfer funnel 16 from above the roller 12'. If the receiving box IT is traversed in the left-right direction (perpendicular to the plane of the paper), the receiving box IT will be housed in the box with an even thickness. After storing a fixed length (fixed amount), the bundle of curled yarn is cut. If the bundle is to be transferred to post-processing within the same factory, it can be moved as is, but if it is to be sent to a remote location, the bundle of curled yarn in the box may be compressed in the height direction and shipped as a compact package. In Figure 1, the push box part is compared to other parts,
In particular, it is shown in an enlarged view. In some cases, the bottom plate of the push box is pushed up with constant pressure air to adjust the height of the push box.
If the type of thread to be threaded, the overall denier and thickness of the feeding system are constant, a fixed-walled push box may be sufficient.

In any case, the crimped yarn bundle is discharged at a constant speed in a form in which 25 to 35% of the cross-sectional area of the push box is the total cross-sectional area of the fibers. If the purpose is to permanently fix the crimping, the method of Patent No. 697100 is used, although not shown, by guiding the breathable fabric below the roller 12 and at least half the circumference of the crimped yarn bundle. with a shape that wraps around v, rollers 12 and 13
is used as a pinch roller, the coated crimped yarn bundle is continuously passed through a pressure steam chamber, the crimped yarn bundle pulled out by the pinch roller is decoated, the fabric is circulated to the inlet side, and the crimped yarn bundle is passed through a predetermined position. The method is to cut it into lengths and store them at the back. A yarn manufacturer uses a twisted yarn bundle in the same factory to create a twisting machine,
When performing post-processing on a copper winding machine, loom, orthogonal non-woven fabric machine, etc., the container and method for storing the curled yarn bundle may be arbitrary; however, when performing the above-mentioned post-processing at another remote factory, The material is then transported in quantitative packaging, unpacked at a processing factory, unwound and warped by the method illustrated in FIG. Second
In the figure, the curled yarn bundle 22 that has been unwrapped and pulled upward from the storage box 21 is placed in one or several sets in parallel on a high guide rod 2.
3, the loop is unraveled and the yarn bundle becomes a single band.The width of the crimped yarn bundle is widened through the guide rods 24, 25, and 26, which are a combination of straight rods and curved rods, and are sent to the vertical steam chamber 2T. Inside, straight and curved guide rods 28 and 29 in a zigzag arrangement are installed inside.
, 30, 31, and 32 and softening due to steam heating, the crimping is sequentially extended, the width of the yarn bundle is expanded, and each part of the yarn bundle is steamed uniformly. and then moved forward.

Live steam is supplied to the bottom of the chamber through a pipe 34, and condensate accumulated at the bottom of the chamber is removed through a pipe 35. The position of the guide rod within the steam chamber is moved in the horizontal direction to change the contact angle with the crimped yarn bundle so that the guide rod is positioned so that most of the crimped yarn is stretched within the chamber. Immediately after being exposed to the outside air, the yarn bundle absorbs moisture and prevents static electricity.
Comb 40, 41, 4 while passing over 6, 3T38, 39
2, 43, etc., and then passed between take-up pinch rollers 44, 44, warped to a constant pitch and constant width, and directly introduced into a post-processing machine 45. Although the drawing shows a vertically moving type of thread splitting process, the thread may also be split in a horizontal path. If the yarn is to be modified into a yarn with less shrinkage by additional heat stretching or relaxation heat treatment, several hot drums, pinch rollers, etc. are installed after the pinch rollers 44 and 44' (not shown). They can be placed and heated using the difference in circumferential speed. The same applies when the yarn is subjected to special sizing or other post-processing processing. The method of determining the arrangement order of the yarns for dividing yarn is as follows: When the parallel yarn bundles have been fed for a packing unit length, the middle of the two layers of parallel yarn bundles that are fed along the upper and lower roller surfaces at the inlet side of the push roller. Insert separately prepared thin colored threads with hot melt glue into two places at intervals so that they protrude from the sides more than the full width of the width, and insert the crimped thread bundle between the above two marks on the exit side of the push box. If it is cut, there are marks that fix the arrangement order of the threads near the front and rear ends of the bundle of curled threads for each packing unit, so the threads can be divided using these marks as a guide.

Since the curled yarn bundle is crimped into a flat plate-like shape, the arrangement order can be easily determined even without the above marks in the case of thick denier yarns. If care is taken to avoid false twisting during the process of unwinding the flat-wound bundle of yarn, the dividing operation will proceed smoothly. The present method is a yarn manufacturing process, and the spinning speed is 100 m/W, such as the wet spinning method of recycled cellulose, acrylic, etc.
After melt-spinning at a spinning speed of 200 to 300 m/111 t, such as dry spinning for acetate and acrylic, and at a speed of 1000 m/m or more, as in the case of polyester and nylon, many yarns are paralleled to produce 200 yarns. ~300m/
150 to 500 m/71i as in the case of parallel stretching post-treatment with Wt, and in the case of polyolefin flat yarns, split yarns, and monofilaments! This applies to the manufacturing and processing of all man-made fibers, including cases of l.

Example 1 A water-cooled high-density polyethylene film with a thickness of 0.0611 was slit to a width of 20U, and stretched and heat-treated to form a 1000d×
At the end where 75 flat yarns run at 160 m/Wt, the yarns are heated with steam before being fed to the push crimping machine, and a push 20 roller rotating at the same speed has a width of 501 m and a diameter of 1.
2011, the push-in crimping machine shown in Fig. 1 has a simple height of 10 WII. It has a cross section of × width 5011, and is passed through a push-in box with a fixed wall that does not inject pressurized steam into the box.
A 400,000 denier crimped yarn bundle 5, which was discharged at a rate of 8.6 m/frame, was moved between conveyor belts as shown in FIG. 1 and packed into cardboard boxes in units of 100 kg.

The discharge speed of the curled yarn bundle was 1/18.6 of the yarn feeding speed, and the yarn bundle length was 12,000 m. If the yarn was heated with steam before the pushing roller without introducing steam into the pushing box, the crimped yarn bundle discharged from the pushing box would maintain its shape stably. 4 of these rolled and crinkled yarn bundle storage boxes were
2-124976, and the bundle of crimped yarn drawn out from 24 boxes in both warp and warp directions was stretched out under steam heating using the method shown in Fig. 2. 75 x 2 = 150 pieces were warped to 3 pieces/inch and laminated in the warp and warp to obtain two 6000 m rolls of 50 inch wide 3 pieces/inch orthogonal nonwoven fabric.

This orthogonal nonwoven fabric was suitable for light reinforcement of paper and films. When using a flat yarn as in this example, it is usually 100%
0d yarn has a width of 6.5 to 7m1, so when guiding it to a narrow pushing roller, the width direction of the yarn is set vertically and the parallel width of the parallel yarns is narrowed and the number of parallel yarns is narrowed between the u and v combs. Guide the books one by one and pass them through the push crimping machine in a shogi-like manner overlapping the surface of the push roller.

In addition, when warping is performed at a high density such as 10 yarns/inch, the yarns are warped thinly by L/1 after the pinch rollers 44 and 44' in Figure 2.
The yarn, folded into narrow widths, is passed through a 1-tooth comb and then placed on a heated drum with grooves of 2 to 311 widths on its surface.
After being heat-set to a narrow width, the yarn is warped so that all the yarns are lined up on the same plane, and then fed as the warp and weft of an orthogonal nonwoven fabric machine. This folding and heat setting is convenient for woven fabrics as it also acts as a fluff presser. Nylon, polyester carpet yarn, like tire cord, 8
The filament yarn with a thickness of 00 to 1200 d is approximately Example 1.
is processed in the same way.

Example 2 A 600 d undrawn yarn drawn from 200 melt-spun polyester threads was drawn in parallel to four times its original length while being rolled between 300,111 m wide cantilever heated rollers, and then Heat treated at 220'C through 200℃
150d x 200 parallel yarns running at m/m are
As shown in the figure, 100 pieces are divided into 2 groups, upper and lower, and 1.511
Five combs are passed in sequence from bottom to top between each diagonal comb of the pitcher and guided onto a pushing roller measuring 30111 mm in width x 120 mm in diameter. The method was used to push the yarn into a box with a height of 9m1 x width of 30mm, and the fiber filling rate was 0.3, resulting in a bundle of 1,070,000 d in thickness and 5.6 m/Wt (1/36). The yarn bundle discharged at a speed of 1 minute (lower speed) is wrapped in cotton cloth using the method described in Patent No. 697100, passed through a pressure steam chamber at 135°C, subjected to a wet heat setting of crimping for 1 minute, and then released from the pressure steam chamber. The discharged fabric-covered crimped yarn bundle was uncoated and then traversed back and forth to be shipped in 100 kg units in cardboard boxes.

This bundle of curled yarn is sent to a weaving factory) Before the twisting machine, in the process of vertically pulling it out using the method shown in Figure 2, only the bundle of curled yarn passes through a steam heating chamber, passes through a splitting process, and is transferred to a 200-spin twisting machine. It was directly connected and wound on a spindle rotating at 10,000 revolutions per minute at a twisting rate of 300 T/m at a speed of 33 m/min, and used as a woven yarn.

Transferring to a necessary or advantageous post-processing step, parallel yarns are pulled out from one or multiple sets of the above-mentioned crimped yarn bundles, and the multiple yarns separated into individual yarns are directly connected as they are while stretching the crimped yarns. , the method of supplying the yarn to the post-processing step is characterized in that parallel yarns are pulled out from the bundle of crimped yarns transferred to the post-processing step, and the crimps are stretched under heating in the presence of moisture and divided into individual yarns. A method for winding, crinkling, bundling, and taking over a large number of parallel yarns.
