Description

[Detailed description of the invention] Air texturing method and apparatus for carrying out this method The present invention supplies yarn to a first feeding device, and from the first feeding device, texture treatment is performed. a glass fiber fed to a gun nozzle and then fed to a second feeding device. A method of air texturing a yarn comprising: a first and a second feeding device; , a texturing nozzle disposed between both supply devices. The present invention relates to an apparatus for implementing the method.

A thread, for example a thread made of glass fibers, is passed through the first feeding device without twisting. It is already known that it is fed to the texture song nozzle and from there to the second feeding device. It is being In this case, the individual filaments of the fed yarn are textured The filament may break when inserted into the filament nozzle. This may cause cracking and eventually breakage of the thread. Guide separately like this The untwisted threads are controlled in the texturing nozzle. It expands unevenly. The textured yarn thus obtained (G atn) is not satisfactory for a wide range of applications.

Furthermore, it is known to bring the yarn together with a spinning reel and impart rotation to it.

The yarn thus obtained is fed to a texturing nozzle. The thread is twisted The broken filaments as described above are bundled together. filamen Avoid damaged filaments at the inlet of the texturing nozzle by bundling them together. This prevents misalignment. These yarns also create a textured texture that expands evenly. Yarn is obtained.

However, a disadvantage of this known method is that the filament bundling process is It requires a separate step before being fed to the charging nozzle, which requires considerable cost. This would require a strike. Also, if the thread is made of a relatively brittle material, Another disadvantage is that auxiliary means are required to bundle the filaments. For this reason, the example If the yarn is made of glass fiber, it can be used for so-called texturing. A known method is to coat the threads with glue, but this method Not only does it require additional costs, but it also requires e.g. Disadvantages arise when the application is made in a way that makes it difficult.

The object of the present invention is to reliably texture the yarn to be textured at low cost. It can be fed into a ring nozzle where it can be uniformly textured and its removal By reducing the load applied to the light, even difficult materials can be processed. Providing methods and devices of the type mentioned at the outset, which do not require the use of auxiliary means; It is to be.

In the case of the method of the type mentioned at the outset, the above problem can be solved according to the invention by feeding at least the texture of the yarn separately, i.e. separately feeding the first feeding device; applying a temporary twist to the area between the intake and outlet of the carrying nozzle; The solution is to combine the entirety of the supplied yarn into one unit.

A pre-treatment, such as a twisting step, must be carried out before feeding to the first feeding device. There's no need. Adding a temporary twist and thereby combining the two into a single unit The yarn pieces are bundled together. Therefore, it got stuck at the inlet of the texturing nozzle. It will not move or shift. When you insert it into the texturing nozzle like this By combining the yarns into one unit, the yarn can be expanded evenly. can.

According to an advantageous embodiment of the invention, the yarn is transferred between the texturing nozzle and the second feeding device. between the first supply device and the temporary twister, and the temporary twister connects the first supply device with the temporary twister. Rotation can be imparted to the thread between machines.

After the yarn passes through the texturing nozzle, it is guided through a false twister, so that Rotation is applied to the yarn between the first feeding device and the twister. This rotation allows the supply The entire strand of thread forms a single unit that traps filament fragments. tied together. Therefore, it is necessary to texture yarns that have been twisted in this way. can be accurately loaded into the gun nozzle. The unit thus formed is completely exposed to the blown air, even within the texturing nozzle.

Therefore, rather than individual threads being air treated, the entire unit is air treated. . As a result, the yarn can be expanded uniformly.

These advantages cannot be obtained by performing the twisting and winding processes separately. By installing a temporary twisting machine of arbitrary structure in the yarn processing process, That's what you get.

Furthermore, according to an advantageous embodiment of the method according to the invention, the area of the texturing nozzle It is possible to apply a rotation of 150 T/m or less to the yarn. Usually the texture It is advantageous to subject the yarn to a rotation of less than 100 T/m in the region of the carrying nozzle. . Such rotation is applied when loading the yarn into the texturing nozzle and Air blowing in the texturing nozzle guarantees the desired advantages of the process. It is something that On the other hand, since there is less rotation of the thread, the load acting on each filament is can be reduced, thus reducing the risk of damage.

Furthermore, according to an advantageous embodiment of the method according to the invention, fj of the texturing nozzle A Z-rotation or an S-rotation can be imparted to the yarn in the l region. This allows the Special effects can be added to Cuschard thread.

Furthermore, according to an advantageous embodiment of the method according to the invention, twisted threads and/or twisted Unused yarn can be fed to the first feeding device. Synchronization of thread material and rotation This gives textured yarns special properties, especially with regard to their strength, elongation and volume. Ru.

According to the invention, the apparatus for carrying out the method according to the invention comprises A temporary twister is arranged between the nozzle and the second supply device, and a turning body of the temporary twister is configured to A twisting bin rotatably supported around its own axis, the axis of the twisting bin being The line is inclined with respect to the thread conveyance direction, and the diameter of the twisting bin is 4 mm or more. It is characterized by

By rotatably supporting the twisting bin, the yarn is Friction is reduced and therefore loads are reduced. The thread guide allows the thread to pass through the twist bin. Sometimes this can be done in such a way that contact between the twisted parts is avoided. in the direction of thread transport Because the twist bin is tilted, when the thread passes through the twist bin, This prevents contact between the twists of the yarns, thus preventing damage to the material.

Since the diameter of the twist bottle is 4 mm or more, it is possible to process relatively brittle materials. Ru.

Finally, according to an advantageous configuration of the device according to the invention, the temporary twister can be used for texturing The distance to the nozzle can be adjusted.

The individual dimensions, e.g. diameter of the twist bin, provisional values for the texturing nozzle, etc. The adjustment and selection of the position of the pulverizer, as well as the turning performed within the feeding device, It goes without saying that it should be adapted to the conditions and yarn count of each case.

Next, one embodiment of the present invention will be described using the accompanying drawings.

FIG. 1 is a diagram showing a texturing device according to the present invention; FIG. 2 is a plan view of the temporary twister as seen in the direction of arrow A in FIG.

In the embodiment illustrated in FIG. 1, three untwisted threads 1, 2.3 are As a filament, it is fed to a first supply device 4 of conventional configuration. Threads 1, 2.3 are , after leaving the supply device 4 it reaches the texturing nozzle 6 via the intake 5. and is discharged from the output lower. The yarn 1.2.3 is then passed through a twister 9 to a second supply It is guided into the device 10 and withdrawn from there in the direction of the arrow 11.

The structure of the texturing nozzle 6 is the same as a known one. This texture The thread passing through the nozzle 6 is 1°2? 3 is a pressure inside the texturing nozzle 6. It is inflated in a known manner by being sprayed with compressed air.

The temporary twister 9 is equipped with a drive device (not shown).

This drive device causes the temporary twister 9 to rotate around an axis extending in the conveying direction. It will be done. The drive device has a ring 12. Inside the ring 12 is a twisting bottle 13. Retained. The torsion pin 13 is arranged around an axis extending in the diagonal direction of the ring 12. It is supported so that it can rotate according to arrow 14. Axis of twist bottle 13 is not transverse to the yarn transport direction, but is inclined.

The thread forms a loop in the twist bin 13. The beginning and end of this ring are torsion bins. 13 is slanted, so they do not come into contact. The twisting bin 13 is Rotate. The relative velocity between the outer surface of the twist bottle 13 and the thread is zero.

The space between the texturing nozzle 6 and the texturing nozzle 6 can be adjusted. The device can be adapted to the requirements regarding the material and yarn count.

The withdrawal speeds of the feeding devices 4, 10 are synchronized with each other, as is known, so that the expansion of the material The shortening caused by is taken into account.

In the embodiment thus illustrated, the thread 1.2.3 is connected to the first feeding device 4 and textured. It is supplied to the temporary twister 9 via the ring nozzle 6. Temporary twister 9 rotates This causes the threads 1, 2.3 to rotate. The rotation speed at this time is less than 100T/m. It's advantageous. In this way, the yarns 1, 2, . 3 are combined into one closed unit and the texturing nozzle is supplied from the intake 5. It is drawn into Zuru 6. The number of revolutions given to the thread per unit length is determined by Determined according to the properties of the thread. In this case, the quality of the material is also taken into account and the selected material It is not adjusted appropriately depending on the rotation speed.

The textured yarn is given rotation even after leaving the output loa. It's a known assumption Due to the twisting effect, the yarn does not rotate after passing through the twister 9 and therefore expands further. do.

By means of the method according to the invention and the device for carrying out this method, a yarn capable of expansion is obtained. is processed. The method and device according to the invention ensure that the yarn is not damaged, so that e.g. It is also possible to process relatively brittle threads such as glass fibers.
